Design of outdoor public areas, landmarks, and structures

 

Landscape architecture is the design of outdoor areas, landmarks, and structures to achieve environmental, social-behavioural, or aesthetic outcomes.^[2] It involves the systematic design and general engineering of various structures for construction and human use, investigation of existing social, ecological, and soil conditions and processes in the landscape, and the design of other interventions that will produce desired outcomes.

The scope of the profession is broad and can be subdivided into several sub-categories including professional or licensed landscape architects who are regulated by governmental agencies and possess the expertise to design a wide range of structures and landforms for human use; landscape design which is not a licensed profession; site planning; stormwater management; erosion control; environmental restoration; public realm, parks, recreation and urban planning; visual resource management; green infrastructure planning and provision; and private estate and residence landscape master planning and design; all at varying scales of design, planning and management. A practitioner in the profession of landscape architecture may be called a landscape architect; however, in jurisdictions where professional licenses are required it is often only those who possess a landscape architect license who can be called a landscape architect.

Definition of landscape architecture

[edit]

A canal design focused on esthetical landscape architecture in Stockholm, Sweden.

A river with concrete walls like those of a flood control channel, a historic flood-control measure using landscape engineering in Houston, Texas. Such channelling, intended to be strictly functional, may make flooding worse, by speeding the flow instead of spreading the pulse of floodwater.^[3][4][5]

Modern landscape architecture is a multi-disciplinary field, incorporating aspects of urban design, architecture, geography, ecology, civil engineering, structural engineering, horticulture, environmental psychology, industrial design, soil sciences, botany, and fine arts. The activities of a landscape architect can range from the creation of public parks and parkways to site planning for campuses and corporate office parks; from the design of residential estates to the design of civil infrastructure; and from the management of large wilderness areas to reclamation of degraded landscapes such as mines or landfills. Landscape architects work on structures and external spaces in the landscape aspect of the design – large or small, urban, suburban and rural, and with "hard" (built) and "soft" (planted) materials, while integrating ecological sustainability.

The most valuable contribution can be made at the first stage of a project to generate ideas with technical understanding and creative flair for the design, organization, and use of spaces. The landscape architect can conceive the overall concept and prepare the master plan, from which detailed design drawings and technical specifications are prepared. They can also review proposals to authorize and supervise contracts for the construction work. Other skills include preparing design impact assessments, conducting environmental assessments and audits, and serving as an expert witness at inquiries on land use issues. The majority of their time will most likely be spent inside an office building designing and preparing models for clients.^{[citation needed]}

History

[edit]

Main article: History of landscape architecture

For the period before 1800, the history of landscape gardening (later called landscape architecture) is largely that of master planning and garden design for manor houses, palaces and royal properties. An example is the extensive work by André Le Nôtre for King Louis XIV of France on the Gardens of Versailles. The first person to write of making a landscape was Joseph Addison in 1712. The term landscape architecture was invented by Gilbert Laing Meason in 1828, and John Claudius Loudon (1783–1843) was instrumental in the adoption of the term landscape architecture by the modern profession. He took up the term from Meason and gave it publicity in his Encyclopedias and in his 1840 book on the Landscape Gardening and Landscape Architecture of the Late Humphry Repton.^[6]

John Claudius Loudon was an established and influential horticultural journalist and Scottish landscape architect whose writings were instrumental in shaping Victorian taste in gardens, public parks, and architecture.^[7] In the Landscape Gardening and Landscape Architecture of the Late Humphry Repton, Loudon describes two distinct styles of landscape gardening existing at the beginning of the 19th century: geometric and natural.^[6] Loudon wrote that each style reflected a different stage of society. The geometric style was “most striking and pleasing,” displaying wealth and taste in an “early state of society” and in “countries where the general scenery was wild, irregular, and natural, and man, comparatively, uncultivated and unrefined.”^[6] The natural style was used in “modern times” and in countries where “society is in a higher state of cultivation," displaying wealth and taste through the sacrifice of profitable lands to make room for such designs. ^[6]

The prominent English landscape designer Humphry Repton (1752-1818) echoed similar ideas in his work and design ideas. In his writings on the use of delineated spaces (e.g. courtyards, terrace walls, fences), Repton states that while the motive for defense no longer exists, the features are still useful in separating "the gardens, which belong to man, and the forest, or desert, which belongs to the wild denizens."^[6] Repton refers to Indigenous peoples as "uncivilized human beings, against whom some decided line of defense was absolutely necessary.”^[6]

The practice of landscape architecture spread from the Old to the New World. The term "landscape architect" was used as a professional title by Frederick Law Olmsted in the United States in 1863^{[citation needed]} and Andrew Jackson Downing, another early American landscape designer, was editor of The Horticulturist magazine (1846–52). In 1841 his first book, A Treatise on the Theory and Practice of Landscape Gardening, Adapted to North America, was published to a great success; it was the first book of its kind published in the United States.^[8] During the latter 19th century, the term landscape architect began to be used by professional landscapes designers, and was firmly established after Frederick Law Olmsted Jr. and Beatrix Jones (later Farrand) with others founded the American Society of Landscape Architects (ASLA) in 1899. IFLA was founded at Cambridge, England, in 1948 with Sir Geoffrey Jellicoe as its first president, representing 15 countries from Europe and North America. Later, in 1978, IFLA's Headquarters were established in Versailles.^[9][10][11]

Fields of activity

[edit]

The variety of the professional tasks that landscape architects collaborate on is very broad, but some examples of project types include:^[12]

• Parks of general design and public infrastructure
• Sustainable development
• Stormwater management including rain gardens, green roofs, groundwater recharge, green infrastructure, and constructed wetlands.
• Landscape design for educational function and site design for public institutions and government facilities
• Parks, botanical gardens, arboretums, greenways, and nature preserves
• Recreation facilities, such as playgrounds, golf courses, theme parks and sports facilities
• Housing areas, industrial parks and commercial developments
• Estate and residence landscape planning and design
• Landscaping and accents on highways, transportation structures, bridges, and transit corridors
• Contributions to urban design, town and city squares, waterfronts, pedestrian schemes
• Natural park, tourist destination, and recreating historical landscapes, and historic garden appraisal and conservation studies
• Reservoirs, dams, power stations, reclamation of extractive industry applications or major industrial projects and mitigation
• Environmental assessment and landscape assessment, planning advice and land management proposals.
• Coastal and offshore developments and mitigation
• Ecological design (any aspect of design that minimizes environmentally destructive impacts by integrating itself with natural processes and sustainability)

Landscape managers use their knowledge of landscape processes to advise on the long-term care and development of the landscape. They often work in forestry, nature conservation and agriculture.^{[citation needed]}

Landscape scientists have specialist skills such as soil science, hydrology, geomorphology or botany that they relate to the practical problems of landscape work. Their projects can range from site surveys to the ecological assessment of broad areas for planning or management purposes. They may also report on the impact of development or the importance of particular species in a given area.^{[citation needed]}

Landscape planners are concerned with landscape planning for the location, scenic, ecological and recreational aspects of urban, rural, and coastal land use. Their work is embodied in written statements of policy and strategy, and their remit includes master planning for new developments, landscape evaluations and assessments, and preparing countryside management or policy plans. Some may also apply an additional specialism such as landscape archaeology or law to the process of landscape planning.^{[citation needed]}

Green roof (or more specifically, vegetative roof) designers design extensive and intensive roof gardens for stormwater management, evapo-transpirative cooling, sustainable architecture, aesthetics, and habitat creation.^[13]

Relation to urban planning

[edit]

Through the 19th century, urban planning became a focal point and central issue in cities. The combination of the tradition of landscape gardening and the emerging field of urban planning offered landscape architecture an opportunity to serve these needs.^[14] In the second half of the century, Frederick Law Olmsted completed a series of parks that continue to have a significant influence on the practices of landscape architecture today. Among these were Central Park in New York City, Prospect Park in Brooklyn, New York and Boston's Emerald Necklace park system. Jens Jensen designed sophisticated and naturalistic urban and regional parks for Chicago, Illinois, and private estates for the Ford family including Fair Lane and Gaukler Point. One of the original eleven founding members of the American Society of Landscape Architects (ASLA), and the only woman, was Beatrix Farrand. She was design consultant for over a dozen universities including: Princeton in Princeton, New Jersey; Yale in New Haven, Connecticut; and the Arnold Arboretum for Harvard in Boston, Massachusetts. Her numerous private estate projects include the landmark Dumbarton Oaks in the Georgetown neighborhood of Washington, D.C.^[15] Since that time, other architects – most notably Ruth Havey and Alden Hopkins – changed certain elements of the Farrand design.^{[citation needed]}

Since this period urban planning has developed into a separate independent profession that has incorporated important contributions from other fields such as civil engineering, architecture and public administration. Urban Planners are qualified to perform tasks independent of landscape architects, and in general, the curriculum of landscape architecture programs do not prepare students to become urban planners.^[16]

Landscape architecture continues to develop as a design discipline and to respond to the various movements in architecture and design throughout the 20th and 21st centuries. Thomas Church was a mid-century landscape architect significant in the profession. Roberto Burle Marx in Brazil combined the International style and native Brazilian plants and culture for a new aesthetic. Innovation continues today solving challenging problems with contemporary design solutions for master planning, landscapes, and gardens.^{[citation needed]}

Ian McHarg was known for introducing environmental concerns in landscape architecture.^[17][18] He popularized a system of analyzing the layers of a site in order to compile a complete understanding of the qualitative attributes of a place. This system became the foundation of today's Geographic Information Systems (GIS). McHarg would give every qualitative aspect of the site a layer, such as the history, hydrology, topography, vegetation, etc. GIS software is ubiquitously used in the landscape architecture profession today to analyze materials in and on the Earth's surface and is similarly used by urban planners, geographers, forestry and natural resources professionals, etc.^{[citation needed]}

European nations enabled the widespread circulation of urban planning strategies by transferring landscaping ideas and practices to overseas colonies. The green belt was a popular landscape practice exported by Britain onto colonial territories such as Haifa (1918-1948).^[19] Spatial mechanisms like the green belt, implemented through the Haifa Bay Plan and the British "Grand Model," were used to enforce political control and civic order and extend western ideas of progress and development.^[19] The Greater London Regional Planning Committee accepted the green belt concept which formed the basis of the 1938 Green Belt Act. The planning prototype demarcated open spaces, distinguished between city and countryside, limited urban growth, and created zoning divisions.^[19] It was used extensively in the British colonies to facilitate British rule through the organized division of landscape and populations. ^[19]

Relation to Indigenous practices

[edit]

Indigenous land management practices create constantly changing landscapes through the use of vegetation and natural systems, contrasting with western epistemologies of the discipline that separate ornament from function.^[20] The discipline of landscape architecture favors western designs made from structured materials and geometric forms.^[20] Landscape architecture history books tend to include projects that contain constructed architectural elements that persist over time, excluding many Indigenous landscape-based designs.^[20]

Landscape architecture textbooks often place Indigenous peoples as a prefix to the official start of the discipline. The widely read landscape history text The Landscape of Man (1964) offers a global history of the designed landscape from past to present, featuring African and other Indigenous peoples in its discussions of Paleolithic man between 500,000 and 8,000 BCE in relation to human migration.^[20] Indigenous land-management practices are described as archaeological rather than a part of contemporary practice. Gardens in Time (1980) also places Indigenous practice as prehistory at the beginning of the landscape architecture timeline. Authors John and Ray Oldham describe Aborigines of Australia as “survivors of an ancient way of life” who provide an opportunity to examine western Australia as a “meeting place of a prehistoric man.”^[20]

In the late 18th century, the landscapes created by aboriginal land and fire management practices appealed to English settlers in Australia.^[20] Journals from the period of early white settlement note the landscape resembling parks and popular designs in English landscape gardens of the same period.^[20] In England, these designs were considered sophisticated and celebrated for the intentional sacrifice of usable land. In Australia, the park-like condition was used to justify British control, citing its emptiness and lack of productive use as a basis for the dispossession of Aboriginal people. ^[20]

Education

[edit]

Landscape Architects are generally required to have university or graduate education from an accredited landscape architecture degree program, which can vary in length and degree title. They learn how to create projects from scratch, such as residential or commercial planting and designing outdoor living spaces^[21] they are willing to work with others to get a better outcome for the customers when doing a project; they will have to learn the basics of how to create a project on a manner of time and will require to get your license in a certain state to be allowed to work; students of Landscape Architects will learn how to interact with clients and will learn how to explain a design from scratch when giving the final project.^[22]

Landscape architecture has been taught in the University of Manchester since the 1950s. The course in the Manchester School of Architecture enables students to gain various bachelor's and master's degrees, including MLPM(Hons) which is accredited by the Landscape Institute and by the Royal Town Planning Institute.^[23]

Profession

[edit]

In many countries, a professional institute, comprising members of the professional community, exists in order to protect the standing of the profession and promote its interests, and sometimes also regulate the practice of landscape architecture. The standard and strength of legal regulations governing landscape architecture practice varies from nation to nation, with some requiring licensure in order to practice; and some having little or no regulation. In Europe, North America, parts of South America, Australia, India, and New Zealand, landscape architecture is a regulated profession.^[24]

Since 1889, with the arrival of the French architect and urbanist landscaper Carlos Thays, recommended to recreate the National Capital's parks and public gardens, it was consolidated an apprentice and training program in landscaping that eventually became a regulated profession, currently the leading academic institution is the UBA University of Buenos Aires"UBA Facultad de Arquitectura, Diseño y Urbanismo" (Faculty of Architecture, Design and Urbanism) offering a Bacherlor's degree in Urban Landscaping Design and Planning, the profession itself is regulated by the National Ministry of Urban Planning of Argentina and the Institute of the Buenos Aires Botanical Garden.^{[citation needed]}

The Australian Institute of Landscape Architects (AILA) provides accreditation of university degrees and non-statutory professional registration for landscape architects. Once recognized by AILA, landscape architects use the title 'Registered Landscape Architect' across the six states and territories within Australia.^{[citation needed]}

AILA's system of professional recognition is a national system overseen by the AILA National Office in Canberra. To apply for AILA Registration, an applicant usually needs to satisfy a number of pre-requisites, including university qualification, a minimum number years of practice and a record of professional experience.^[25]

Landscape Architecture within Australia covers a broad spectrum of planning, design, management, and research. From specialist design services for government and private sector developments through to specialist professional advice as an expert witness.^{[citation needed]}

In Canada, landscape architecture, like law and medicine, is a self-regulating profession pursuant to provincial statute. For example, Ontario's profession is governed by the Ontario Association of Landscape Architects pursuant to the Ontario Association of Landscape Architects Act. Landscape architects in Ontario, British Columbia, and Alberta must complete the specified components of L.A.R.E (Landscape Architecture Registration Examination) as a prerequisite to full professional standing.

Provincial regulatory bodies are members of a national organization, the Canadian Society of Landscape Architects / L'Association des Architectes Paysagistes du Canada (CSLA-AAPC), and individual membership in the CSLA-AAPC is obtained through joining one of the provincial or territorial components.^[26]

ISLA (Indonesia Society of Landscape Architects) is the Indonesian society for professional landscape architects formed on 4 February 1978 and is a member of IFLA APR and IFLA World. The main aim is to increase the dignity of the professional members of landscape architects by increasing their activity role in community service, national and international development. The management of IALI consists of National Administrators who are supported by 20 Regional Administrators (Provincial level) and 3 Branch Managers at city level throughout Indonesia.^{[citation needed]}

Landscape architecture education in Indonesia was held in 18 universities, which graduated D3, Bachelor and Magister graduates. The landscape architecture education incorporate in Association of Indonesian Landscape Architecture Education.^{[citation needed]}

AIAPP (Associazione Italiana Architettura del Paesaggio) is the Italian association of professional landscape architects formed in 1950 and is a member of IFLA and IFLA Europe (formerly known as EFLA). AIAPP is in the process of contesting this new law which has given the Architects' Association the new title of Architects, Landscape Architects, Planners and Conservationists whether or not they have had any training or experience in any of these fields other than Architecture. In Italy, there are several different professions involved in landscape architecture:

• Architects
• Landscape designers
• Doctor landscape agronomists and Doctor landscape foresters, often called Landscape agronomists.
• Agrarian Experts and Graduated Agrarian experts.

The New Zealand Institute of Landscape Architects (NZILA) is the professional body for Landscape Architects in NZ.^[27]

In April 2013, NZILA jointly with AILA, hosted the 50th International Federation of Landscape Architects (IFLA) World Congress in Auckland, New Zealand. The World Congress is an international conference where Landscape Architects from all around the globe meet to share ideas around a particular topic.^{[citation needed]}

Within NZ, Members of NZILA when they achieve their professional standing, can use the title Registered Landscape Architect NZILA.^{[citation needed]}

NZILA provides an education policy and an accreditation process to review education programme providers; currently there are three accredited undergraduate Landscape Architecture programmes in New Zealand. Lincoln University also has an accredited masters programme in landscape architecture.^{[citation needed]}

Landscape architecture in Norway was established in 1919 at the Norwegian University of Life Sciences (NMBU) at Ås. The Norwegian School of Landscape Architecture at the Faculty of Landscape and Society is responsible for Europe's oldest landscape architecture education on an academic level. The departments areas include design and design of cities and places, garden art history, landscape engineering, greenery, zone planning, site development, place making and place keeping.^{[citation needed]}

In May 1962, Joane Pim, Ann Sutton, Peter Leutscher and Roelf Botha (considered the forefathers of the profession in South Africa) established the Institute for Landscape Architects, now known as the Institute for Landscape Architecture in South Africa (ILASA).^[28] ILASA is a voluntary organisation registered with the South African Council for the Landscape Architectural Profession (SACLAP).^[29] It consists of three regional bodies, namely, Gauteng, KwaZula-Natal and the Western Cape. ILASA's mission is to advance the profession of landscape architecture and uphold high standards of professional service to its members, and to represent the profession of landscape architecture in any matter which may affect the interests of the members of the institute. ILASA holds the country's membership with The International Federation of Landscape Architects (IFLA).^[30]

In South Africa, the profession is regulated by SACLAP, established as a statutory council in terms of Section 2 of the South African Council for the Landscape Architectural Profession Act – Act 45 of 2000. The Council evolved out of the Board of Control for Landscape Architects (BOCLASA), which functioned under the Council of Architects in terms of The Architectural Act, Act 73 of 1970. SACLAP's mission is to establish, direct, sustain and ensure a high level of professional responsibilities and ethical conduct within the art and science of landscape architecture with honesty, dignity and integrity in the broad interest of public health, safety and welfare of the community.^{[citation needed]}

After completion of an accredited under-graduate and/or post-graduate qualification in landscape architecture at either the University of Cape Town or the University of Pretoria, or landscape technology at the Cape Peninsula University of Technology, professional registration is attained via a mandatory mentored candidacy period (minimum of two years) and sitting of the professional registration exam. After successfully completing the exam, the individual is entitled to the status of Professional Landscape Architect or Professional Landscape Technologist.^{[citation needed]}

Architects Sweden, Sveriges Arkitekter, is the collective trade union and professional organisation for all architects, including landscape architects, in Sweden. The professional body is a member of IFLA (International Federation of Landscape Architects) as well as IFLA Europe.

As a landscape architect, anyone can become a member of Architects Sweden if they have a national or international university degree that is approved by the association. If the degree is from within the European Union, Architects Sweden approves Landscape architect educations listed by IFLA Europe. For educations outside the EU, the association makes an assessment on a statement from the Swedish Council for Higher Education (UHR).

The UK's professional body is the Landscape Institute (LI). It is a chartered body that accredits landscape professionals and university courses. At present there are fifteen accredited programmes in the UK. Membership of the LI is available to students, academics and professionals, and there are over 3,000 professionally qualified members.^{[citation needed]}

The Institute provides services to assist members including support and promotion of the work of landscape architects; information and guidance to the public and industry about the specific expertise offered by those in the profession; and training and educational advice to students and professionals looking to build upon their experience.^{[citation needed]}

In 2008, the LI launched a major recruitment drive entitled "I want to be a Landscape Architect" to encourage the study of Landscape Architecture. The campaign aimed to raise the profile of landscape architecture and highlight its valuable role in building sustainable communities and fighting climate change.^[31]

As of July 2018, the "I want to be a Landscape Architect" initiative was replaced by a brand new careers campaign entitled #ChooseLandscape, which aims to raise awareness of landscape as a profession; improve and increase access to landscape education; and inspire young people to choose landscape as a career.^[32] This new campaign includes other landscape-related professions such as landscape management, landscape planning, landscape science and urban design.^[33]

In the United States, landscape architecture is regulated by individual state governments. For a landscape architect, obtaining licensure requires advanced education and work experience, plus passage of the national examination called the Landscape Architect Registration Examination (L.A.R.E.). Licensing is overseen at the national level by the Council of Landscape Architectural Registration Boards (CLARB). Several states require passage of a state exam as well.

Landscape architecture has been identified as an above-average growth profession by the US Bureau of Labor Statistics and was listed in U.S. News & World Report's list of Best Jobs to Have in 2006, 2007, 2008, 2009 and 2010.^[34] The national trade association for United States landscape architects is the American Society of Landscape Architects. Frederick Law Olmsted, who designed Central Park in New York City, is known as the "father of American landscape architecture".^[35]

Las Vegas,^[a] colloquially referred to as Vegas, is the most populous city in the U.S. state of Nevada and the seat of Clark County. The Las Vegas Valley metropolitan area is the largest within the greater Mojave Desert, and second-largest in the Southwestern United States. According to the United States Census Bureau, the city had 641,903 residents in 2020,^[9] with a metropolitan population of 2,227,053,^[10] making it the 24th-most populous city in the United States. Las Vegas is an internationally renowned major resort city, known primarily for its gambling, shopping, fine dining, entertainment, and nightlife, with most venues centered on downtown Las Vegas and more to the Las Vegas Strip just outside city limits in the unincorporated towns of Paradise and Winchester. The Las Vegas Valley serves as the leading financial, commercial, and cultural center in Nevada.

Las Vegas was settled in 1905 and officially incorporated in 1911.^[11] At the close of the 20th century, it was the most populated North American city founded within that century (a similar distinction was earned by Chicago in the 19th century). Population growth has accelerated since the 1960s and into the 21st century, and between 1990 and 2000 the population increased by 85.2%.

The city bills itself as the Entertainment Capital of the World, and is famous for its luxurious and large casino-hotels. With over 40.8 million visitors annually as of 2023,^[12] Las Vegas is one of the most visited cities in the United States, annually ranking as one of the world's most visited tourist destinations.^[13][14] It is the third most popular U.S. destination for business conventions^[15] and a global leader in the hospitality industry.^[16] The city's tolerance for numerous forms of adult entertainment has earned it the nickname "Sin City",^[17] and has made it a popular setting for literature, films, television programs, commercials and music videos.

In 1829, Mexican trader and explorer Antonio Armijo led a group consisting of 60 men and 100 mules along the Old Spanish Trail from modern day New Mexico to California. Along the way, the group stopped in what would become Las Vegas and noted its natural water sources, now referred to as the Las Vegas Springs, which supported extensive vegetation such as grasses and mesquite trees. The springs were a significant natural feature in the valley, with streams that supported a meadow ecosystem. This region served as the winter residence for the Southern Paiute people, who utilized the area's resources before moving to higher elevations during the summer months. The Spanish "las vegas" or "the meadows" (more precisely, lower land near a river) in English, was applied to describe the fertile lowlands near the springs. Over time, the name began to refer to the populated settlement.^[18][19][20]

Nomadic Paleo-Indians traveled to the Las Vegas area 10,000 years ago, leaving behind petroglyphs. Ancient Puebloan and Paiute tribes followed at least 2,000 years ago.^[21]

A young Mexican scout named Rafael Rivera is credited as the first non-Native American to encounter the valley, in 1829.^[22] Trader Antonio Armijo led a 60-man party along the Spanish Trail to Los Angeles, California, in 1829.^[23][24] In 1844, John C. Frémont arrived, and his writings helped lure pioneers to the area. Downtown Las Vegas's Fremont Street is named after him.

Eleven years later, members of the Church of Jesus Christ of Latter-day Saints chose Las Vegas as the site to build a fort halfway between Salt Lake City and Los Angeles, where they would travel to gather supplies. The fort was abandoned several years afterward. The remainder of this Old Mormon Fort can still be seen at the intersection of Las Vegas Boulevard and Washington Avenue.

Las Vegas was founded as a city in 1905, when 110 acres (45 ha) of land adjacent to the Union Pacific Railroad tracks were auctioned in what would become the downtown area. In 1911, Las Vegas was incorporated as a city.^[25]

The year 1931 was pivotal for Las Vegas. At that time, Nevada legalized casino gambling^[26] and reduced residency requirements for divorce to six weeks.^[27] This year also witnessed the beginning of construction of the tunnels of nearby Hoover Dam. The influx of construction workers and their families helped Las Vegas avoid economic calamity during the Great Depression. The construction work was completed in 1935.

In late 1941, Las Vegas Army Airfield was established. Renamed Nellis Air Force Base in 1950, it is now home to the United States Air Force Thunderbirds aerobatic team.^[28]

Following World War II, lavishly decorated hotels, gambling casinos, and big-name entertainment became synonymous with Las Vegas.

In 1951, nuclear weapons testing began at the Nevada Test Site, 65 miles (105 km) northwest of Las Vegas. During this time, the city was nicknamed the "Atomic City." Residents and visitors were able to witness the mushroom clouds (and were exposed to the fallout) until 1963 when the Partial Nuclear Test Ban Treaty required that nuclear tests be moved underground.^[29]

In 1955, the Moulin Rouge Hotel opened and became the first racially integrated casino-hotel in Las Vegas.

During the 1960s, corporations and business tycoons such as Howard Hughes were building and buying hotel-casino properties. Gambling was referred to as "gaming," which transitioned it into a legitimate business. Learning from Las Vegas, published during this era, asked architects to take inspiration from the city's highly decorated buildings, helping to start the postmodern architecture movement.

In 1995, the Fremont Street Experience opened in Las Vegas's downtown area. This canopied five-block area features 12.5 million LED lights and 550,000 watts of sound from dusk until midnight during shows held at the top of each hour.

Due to the realization of many revitalization efforts, 2012 was dubbed "The Year of Downtown." Projects worth hundreds of millions of dollars made their debut at this time, including the Smith Center for the Performing Arts, the Discovery Children's Museum, the Mob Museum, the Neon Museum, a new City Hall complex, and renovations for a new Zappos.com corporate headquarters in the old City Hall building.^[30][31]

Las Vegas is the county seat of Clark County, in a basin on the floor of the Mojave Desert,^[32] and is surrounded by mountain ranges. Much of the landscape is rocky and arid, with desert vegetation and wildlife. It can be subjected to torrential flash floods, although much has been done to mitigate the effects of flash floods through improved drainage systems.^[33]

The city's elevation is approximately 2,030 ft (620 m) above sea level, though the surrounding peaks reach elevations of over 10,000 feet (3,000 m) and act as barriers to the strong flow of moisture from the surrounding area. According to the United States Census Bureau, the city has an area of 135.86 sq mi (351.9 km²), of which 135.81 sq mi (351.7 km²) is land and 0.05 sq mi (0.13 km²) (0.03%) is water.

After Alaska and California, Nevada is the third most seismically active state in the U.S. It has been estimated by the United States Geological Survey (USGS) that over the next 50 years, there is a 10–20% chance of an M6.0 or greater earthquake occurring within 50 km (31 mi) of Las Vegas.^[34]

Within the city are many lawns, trees, and other greenery. Due to water resource issues, there has been a movement to encourage xeriscapes. Another part of conservation efforts is scheduled watering days for residential landscaping. A U.S. Environmental Protection Agency grant in 2008 funded a program that analyzed and forecast growth and environmental effects through 2019.^[35]

Las Vegas has a subtropical hot desert climate (Köppen climate classification: BWh, Trewartha climate classification BWhk), typical of the Mojave Desert in which it lies. This climate is typified by long, extremely hot summers; warm transitional seasons; and short winters with mild days and cool nights. There is abundant sunshine throughout the year, with an average of 310 sunny days and bright sunshine during 86% of all daylight hours.^[36][37] Rainfall is scarce, with an average of 4.2 in (110 mm) dispersed between roughly 26 total rainy days per year.^[38] Las Vegas is among the sunniest, driest, and least humid locations in North America, with exceptionally low dew points and humidity that sometimes remains below 10%.^[39]

The summer months of June through September are extremely hot, though moderated by the low humidity levels. July is the hottest month, with an average daytime high of 104.5 °F (40.3 °C). On average, 137 days per year reach or exceed 90 °F (32 °C), of which 78 days reach 100 °F (38 °C) and 10 days reach 110 °F (43 °C). During the peak intensity of summer, overnight lows frequently remain above 80 °F (27 °C), and occasionally above 85 °F (29 °C).^[36]

While most summer days are consistently hot, dry, and cloudless, the North American Monsoon sporadically interrupts this pattern and brings more cloud cover, thunderstorms, lightning, increased humidity, and brief spells of heavy rain. Potential monsoons affect Las Vegas between July and August. Summer in Las Vegas is marked by significant diurnal temperature variation. While less extreme than other parts of the state, nighttime lows in Las Vegas are often 30 °F (16.7 °C) or more lower than daytime highs.^[40] The average hottest night of the year is 90 °F (32 °C). The all-time record is at 95 °F (35 °C).^[36]

Las Vegas winters are relatively short, with typically mild daytime temperatures and chilly nights. Sunshine is abundant in all seasons. December is both the year's coolest and cloudiest month, with an average daytime high of 56.9 °F (13.8 °C) and sunshine occurring during 78% of its daylight hours. Winter evenings are defined by clear skies and swift drops in temperature after sunset, with overnight minima averaging around 40 °F (4.4 °C) in December and January. Owing to its elevation that ranges from 2,000 to 3,000 feet (610 to 910 m), Las Vegas experiences markedly cooler winters than other areas of the Mojave Desert and the adjacent Sonoran Desert that are closer to sea level. The city records freezing temperatures an average of 10 nights per winter. It is exceptionally rare for temperatures to reach or fall below 25 °F (−4 °C).^[36]

Most of the annual precipitation falls during the winter. February, the wettest month, averages only four days of measurable rain. The mountains immediately surrounding the Las Vegas Valley accumulate snow every winter, but significant accumulation within the city is rare, although moderate accumulations occur every few years. The most recent accumulations occurred on February 18, 2019, when parts of the city received about 1 to 2 inches (2.5 to 5.1 cm) of snow^[41] and on February 20 when the city received almost 0.5 inches (1.3 cm).^[42] Other recent significant snow accumulations occurred on December 25, 2015, and December 17, 2008.^[43] Unofficially, Las Vegas's largest snowfall on record was the 12 inches (30 cm) that fell in 1909.^[44] In recent times, ice days have not occurred, although 29 °F (−2 °C) was measured in 1963.^[36] On average the coldest day is 44 °F (7 °C).^[36]

The highest temperature officially observed for Las Vegas is 120 °F (48.9 °C), as measured at Harry Reid International Airport on July 7, 2024.^[36][45] The lowest temperature was 8 °F (−13 °C), recorded on two days: January 25, 1937, and January 13, 1963.^[36] The official record hot daily minimum is 95 °F (35 °C) on July 19, 2005, and July 1, 2013. The official record cold daily maximum is 28 °F (−2 °C) on January 8 and 21, 1937.^[36] July 2024 was the hottest month ever recorded in Las Vegas, with its highest recorded mean daily average temperature over the month of 99.9 °F (38 °C), its highest recorded mean daily maximum temperature of 111.5 °F (44 °C), and its highest recorded mean nightly minimum temperature of 88.3 °F (31 °C).^[46]

Due to concerns about climate change in the wake of a 2002 drought, daily water consumption has been reduced from 314 US gallons (1,190 L) per resident in 2003 to around 205 US gallons (780 L) in 2015.^[47]

According to a 2004 study, Las Vegas has one of the highest divorce rates.^[57][58] The city's high divorce rate is not wholly due to Las Vegans themselves getting divorced. Compared to other states, Nevada's nonrestrictive requirements for divorce result in many couples temporarily moving to Las Vegas in order to get divorced.^[59] Similarly, Nevada marriage requirements are equally lax resulting in one of the highest marriage rates of U.S. cities, with many licenses issued to people from outside the area (see Las Vegas weddings).^[59]

The primary drivers of the Las Vegas economy are tourism, gaming, and conventions, which in turn feed the retail and restaurant industries.

The major attractions in Las Vegas are the casinos and the hotels, although in recent years other new attractions have begun to emerge.

Most casinos in the downtown area are on Fremont Street, with The STRAT Hotel, Casino & Skypod as one of the few exceptions. Fremont East, adjacent to the Fremont Street Experience, was granted variances to allow bars to be closer together, similar to the Gaslamp Quarter of San Diego, the goal being to attract a different demographic than the Strip attracts.

The Golden Gate Hotel and Casino, downtown along the Fremont Street Experience, is the oldest continuously operating hotel and casino in Las Vegas; it opened in 1906 as the Hotel Nevada.

In 1931, the Northern Club (now the La Bayou) opened.^[64][65] The most notable of the early casinos may have been Binion's Horseshoe (now Binion's Gambling Hall and Hotel) while it was run by Benny Binion.

Boyd Gaming has a major presence downtown operating the California Hotel & Casino, the Fremont Hotel & Casino, and the Main Street Casino. The Four Queens also operates downtown along the Fremont Street Experience.

Downtown casinos that have undergone major renovations and revitalization in recent years include the Golden Nugget Las Vegas, The D Las Vegas (formerly Fitzgerald's), the Downtown Grand Las Vegas (formerly Lady Luck), the El Cortez Hotel & Casino, and the Plaza Hotel & Casino.^[66]

In 2020, Circa Resort & Casino opened, becoming the first all-new hotel-casino to be built on Fremont Street since 1980.^[67]

The center of the gambling and entertainment industry is the Las Vegas Strip, outside the city limits in the surrounding unincorporated communities of Paradise and Winchester in Clark County. Some of the largest casinos and buildings are there.^[68]

The original Welcome to Fabulous Las Vegas sign

Gateway Arches

In 1929, the city installed a welcome arch over Fremont Street, at the corner of Main Street.^[69][70][71] It remained in place until 1931.^[72][73]

In 1959, the 25-foot-tall (7.6 m) Welcome to Fabulous Las Vegas sign was installed at the south end of the Las Vegas Strip. A replica welcome sign, standing nearly 16 feet (4.9 m) tall, was installed within city limits in 2002, at Las Vegas Boulevard and Fourth Street.^[74][75][76] The replica was destroyed in 2016, when a pickup truck crashed into it.^[77]

In 2018, the city approved plans for a new gateway landmark in the form of neon arches. It was built within city limits, in front of the Strat resort and north of Sahara Avenue.^[78] The project, built by YESCO, cost $6.5 million and stands 80 feet (24 m) high.^[79] Officially known as the Gateway Arches, the project was completed in 2020. The steel arches are blue during the day, and light up in a variety of colors at night.^[80]

Also located just north of the Strat are a pair of giant neon showgirls, initially added in 2018 as part of a $400,000 welcome display. The original showgirls were 25 feet (7.6 m) tall, but were replaced by new ones in 2022, rising 50 feet (15 m).^[81][82] The originals were refurbished following weather damage and installed at the Las Vegas Arts District.^[82][83]

When The Mirage opened in 1989, it started a trend of major resort development on the Las Vegas Strip outside of the city. This resulted in a drop in tourism in the downtown area, but many recent projects have increased the number of visitors to downtown.

An effort has been made by city officials to diversify the economy by attracting health-related, high-tech and other commercial interests. No state tax for individuals or corporations, as well as a lack of other forms of business-related taxes, have aided the success of these efforts.^[84]

The Fremont Street Experience was built in an effort to draw tourists back to the area and has been popular since its startup in 1995.

The city conducted a land-swap deal in 2000 with Lehman Brothers, acquiring 61 acres (25 ha) of property near downtown Las Vegas in exchange for 91 acres (37 ha) of the Las Vegas Technology Center.^[85] In 2004, Las Vegas Mayor Oscar Goodman announced that the area would become home to Symphony Park (originally called "Union Park"^[86]), a mixed-use development. The development is home to the Cleveland Clinic Lou Ruvo Center for Brain Health, The Smith Center for the Performing Arts, the Discovery Children's Museum, the Las Vegas Chamber of Commerce, and four residential projects totaling 600 residential units as of 2024.^[87]

In 2005, the World Market Center opened, consisting of three large buildings taking up 5,400,000 square feet (500,000 m²). Trade shows for the furniture and furnishing industries are held there semiannually.^[88]

Also nearby is the Las Vegas North Premium Outlets. With a second expansion, completed in May 2015, the mall currently offers 175 stores.^[89]

City offices moved to a new Las Vegas City Hall in February 2013 on downtown's Main Street. The former city hall building is now occupied by the corporate headquarters for the online retailer Zappos.com, which opened downtown in 2013. Zappos CEO Tony Hsieh took an interest in the urban area and contributed $350 million toward a revitalization effort called the Downtown Project.^[90][91] Projects funded include Las Vegas's first independent bookstore, The Writer's Block.^[92]

A number of new industries have moved to Las Vegas in recent decades. Zappos.com (now an Amazon subsidiary) was founded in San Francisco but by 2013 had moved its headquarters to downtown Las Vegas. Allegiant Air, a low-cost air carrier, launched in 1997 with its first hub at Harry Reid International Airport and headquarters in nearby Summerlin.

Planet 13 Holdings, a cannabis company, opened the world's largest cannabis dispensary in Las Vegas at 112,000 sq ft (10,400 m²).^[93][94]

A growing population means the Las Vegas Valley used 1.2 billion US gal (4.5 billion L) more water in 2014 than in 2011. Although water conservation efforts implemented in the wake of a 2002 drought have had some success, local water consumption remains 30 percent greater than in Los Angeles, and over three times that of San Francisco metropolitan area residents. The Southern Nevada Water Authority is building a $1.4 billion tunnel and pumping station to bring water from Lake Mead, has purchased water rights throughout Nevada, and has planned a controversial $3.2 billion pipeline across half the state. By law, the Las Vegas Water Service District "may deny any request for a water commitment or request for a water connection if the District has an inadequate supply of water." But limiting growth on the basis of an inadequate water supply has been unpopular with the casino and building industries.^[47]

The city is home to several museums, including the Neon Museum (the location for many of the historical signs from Las Vegas's mid-20th century heyday), The Mob Museum, the Las Vegas Natural History Museum, the Discovery Children's Museum, the Nevada State Museum and the Old Las Vegas Mormon Fort State Historic Park.

With some exceptions, including Las Vegas Boulevard, Boulder Highway (SR 582) and Rancho Drive (SR 599), the majority of surface streets in Las Vegas are laid out in a grid along Public Land Survey System section lines. Many are maintained by the Nevada Department of Transportation as state highways. The street numbering system is divided by the following streets:

• Westcliff Drive, US 95 Expressway, Fremont Street and Charleston Boulevard divide the north–south block numbers from west to east.
• Las Vegas Boulevard divides the east–west streets from the Las Vegas Strip to near the Stratosphere, then Main Street becomes the dividing line from the Stratosphere to the North Las Vegas border, after which the Goldfield Street alignment divides east and west.
• On the east side of Las Vegas, block numbers between Charleston Boulevard and Washington Avenue are different along Nellis Boulevard, which is the eastern border of the city limits.

Interstates 15, 11, and US 95 lead out of the city in four directions. Two major freeways – Interstate 15 and Interstate 11/U.S. Route 95 – cross in downtown Las Vegas.

Artificial turf is a surface of synthetic fibers made to look like natural grass, used in sports arenas, residential lawns and commercial applications that traditionally use grass. It is much more durable than grass and easily maintained without irrigation or trimming, although periodic cleaning is required. Stadiums that are substantially covered and/or at high latitudes often use artificial turf, as they typically lack enough sunlight for photosynthesis and substitutes for solar radiation are prohibitively expensive and energy-intensive. Disadvantages include increased risk of injury especially when used in athletic competition, as well as health and environmental concerns about the petroleum and toxic chemicals used in its manufacture.

Artificial turf first gained substantial attention in 1966, when ChemGrass was installed in the year-old Astrodome, developed by Monsanto and rebranded as AstroTurf, now a generic trademark (registered to a new owner) for any artificial turf.

The first-generation system of shortpile fibers without infill of the 1960s has largely been replaced by two more. The second features longer fibers and sand infill and the third adds recycled crumb rubber to the sand. Compared to earlier systems, modern artificial turf more closely resembles grass in appearance and is also considered safer for athletic competition. However, it is still not widely considered to be equal to grass. Sports clubs, leagues, unions and individual athletes have frequently spoken out and campaigned against it, while local governments have enacted and enforced laws restricting and/or banning its use.

History

[edit]

David Chaney, who moved to Raleigh, North Carolina, in 1960 and later served as Dean of the North Carolina State University College of Textiles, headed the team of Research Triangle Park researchers who created the first notable artificial turf. That accomplishment led Sports Illustrated to declare Chaney as the man "responsible for indoor major league baseball and millions of welcome mats."

Artificial turf was first installed in 1964 on a recreation area at the Moses Brown School in Providence, Rhode Island.^[1] The material came to public prominence in 1966, when AstroTurf was installed in the Astrodome in Houston, Texas.^[1] The state-of-the-art indoor stadium had attempted to use natural grass during its initial season in 1965, but this failed miserably and the field conditions were grossly inadequate during the second half of the season, with the dead grass painted green. Due to a limited supply of the new artificial grass, only the infield was installed before the Houston Astros' home opener in April 1966; the outfield was installed in early summer during an extended Astros road trip and first used after the All-Star Break in July.

The use of AstroTurf and similar surfaces became widespread in the U.S. and Canada in the early 1970s, installed in both indoor and outdoor stadiums used for baseball and football. More than 11,000 artificial turf playing fields have been installed nationally.^[2] More than 1,200 were installed in the U.S. in 2013 alone, according to the industry group the Synthetic Turf Council.^[2]

Sports applications

[edit]

Baseball

[edit]

Artificial turf was first used in Major League Baseball in the Houston Astrodome in 1966, replacing the grass field used when the stadium opened a year earlier. Even though the grass was specifically bred for indoor use, the dome's semi-transparent Lucite ceiling panels, which had been painted white to cut down on glare that bothered the players, did not pass enough sunlight to support the grass. For most of the 1965 season, the Astros played on green-painted dirt and dead grass.

The solution was to install a new type of artificial grass on the field, ChemGrass, which became known as AstroTurf. Given its early use, the term astroturf has since been genericized as a term for any artificial turf.^[3] Because the supply of AstroTurf was still low, only a limited amount was available for the first home game. There was not enough for the entire outfield, but there was enough to cover the traditional grass portion of the infield. The outfield remained painted dirt until after the All-Star Break. The team was sent on an extended road trip before the break, and on 19 July 1966, the installation of the outfield portion of AstroTurf was completed.

The Chicago White Sox became the first team to install artificial turf in an outdoor stadium, as they used it only in the infield and adjacent foul territory at Comiskey Park from 1969 through 1975.^[4] Artificial turf was later installed in other new multi-purpose stadiums such as Pittsburgh's Three Rivers Stadium, Philadelphia's Veterans Stadium, and Cincinnati's Riverfront Stadium. Early AstroTurf baseball fields used the traditional all-dirt path, but starting in 1970 with Cincinnati's Riverfront Stadium,^[5] teams began using the "base cutout" layout on the diamond, with the only dirt being on the pitcher's mound, batter's circle, and in a five-sided diamond-shaped "sliding box" around each base. With this layout, a painted arc would indicate where the edge of the outfield grass would normally be, to assist fielders in positioning themselves properly. The last stadium in MLB to use this configuration was Rogers Centre in Toronto, when they switched to an all-dirt infield (but keeping the artificial turf) for the 2016 season.^[6][7]

The biggest difference in play on artificial turf was that the ball bounced higher than on real grass and also traveled faster, causing infielders to play farther back than they would normally so that they would have sufficient time to react. The ball also had a truer bounce than on grass so that on long throws fielders could deliberately bounce the ball in front of the player they were throwing to, with the certainty that it would travel in a straight line and not be deflected to the right or left. The biggest impact on the game of "turf", as it came to be called, was on the bodies of the players. The artificial surface, which was generally placed over a concrete base, had much less give to it than a traditional dirt and grass field did, which caused more wear-and-tear on knees, ankles, feet, and the lower back, possibly even shortening the careers of those players who played a significant portion of their games on artificial surfaces. Players also complained that the turf was much hotter than grass, sometimes causing the metal spikes to burn their feet or plastic ones to melt. These factors eventually provoked a number of stadiums, such as the Kansas City Royals' Kauffman Stadium, to switch from artificial turf back to natural grass.

In 2000, St. Petersburg's Tropicana Field became the first MLB field to use a third-generation artificial surface, FieldTurf. All other remaining artificial turf stadiums were either converted to third-generation surfaces or were replaced entirely by new natural grass stadiums. In a span of 13 years, between 1992 and 2005, the National League went from having half of its teams using artificial turf to all of them playing on natural grass. With the replacement of Minneapolis's Hubert H. Humphrey Metrodome by Target Field in 2010, only two MLB stadiums used artificial turf from 2010 through 2018: Tropicana Field and Toronto's Rogers Centre. This number grew to three when the Arizona Diamondbacks switched Chase Field to artificial turf for the 2019 season; the stadium had grass from its opening in 1998 until 2018, but the difficulty of maintaining the grass in the stadium, which has a retractable roof and is located in a desert city, was cited as the reason for the switch.^[8] In 2020, Miami's Marlins Park (now loanDepot Park) also switched to artificial turf for similar reasons, while the Texas Rangers' new Globe Life Field was opened with an artificial surface, as it is also a retractable roof ballpark in a hot weather city; this puts the number of teams using synthetic turf in MLB at five as of 2023.

American football

[edit]

The first professional American football team to play on artificial turf was the Houston Oilers, then part of the American Football League, who moved into the Astrodome in 1968, which had installed AstroTurf two years prior. In 1969, the University of Pennsylvania's Franklin Field in Philadelphia, at the time also home field of the Philadelphia Eagles, switched from grass to AstroTurf, making it the first National Football League stadium to use artificial turf.

In 2002, CenturyLink Field, originally planned to have a natural grass field, was instead surfaced with FieldTurf upon positive reaction from the Seattle Seahawks when they played on the surface at their temporary home of Husky Stadium during the 2000 and 2001 seasons. This would be the first of a leaguewide trend taking place over the next several seasons that would not only result in teams already using artificial surfaces for their fields switching to the new FieldTurf or other similar surfaces but would also see several teams playing on grass adopt a new surface. (The Indianapolis Colts' RCA Dome and the St. Louis Rams' Edward Jones Dome were the last two stadiums in the NFL to replace their first-generation AstroTurf surfaces for next-generation ones after the 2004 season). For example, after a three-year experiment with a natural surface, Giants Stadium went to FieldTurf for 2003, while M&T Bank Stadium added its own artificial surface the same year (it has since been removed and replaced with a natural surface, which the stadium had before installing the turf). Later examples include Paul Brown Stadium (now Paycor Stadium), which went from grass to turf in 2004; Gillette Stadium, which made the switch in 2006;^[9] and NRG Stadium, which did so in 2015. As of 2021, 14 NFL fields out of 30 are artificial. NFL players overwhelmingly prefer natural grass over synthetic surfaces, according to a league survey conducted in 2010. When asked, "Which surface do you think is more likely to shorten your career?", 90% responded artificial turf.^[10] When players were asked "Is the Turf versus Grass debate overblown or a real concern"^[11] in an anonymous player survey, 83% believe it is a real concern while 12.3% believe it is overblown.

Following receiver Odell Beckham Jr.'s injury during Super Bowl LVI, other NFL players started calling for turf to be banned since the site of the game, SoFi Stadium, was a turf field.^[12]

Arena football is played indoors on the older short-pile artificial turf.

Canadian football

[edit]

The first professional Canadian football stadium to use artificial turf was Empire Stadium in Vancouver, British Columbia, then home of the Canadian Football League's BC Lions, which installed 3M TartanTurf in 1970. Today, eight of the nine stadiums in the CFL currently use artificial turf, largely because of the harsh weather conditions in the latter-half of the season. The only one that does not is BMO Field in Toronto, which initially had an artificial pitch and has been shared by the CFL's Toronto Argonauts since 2016 (part of the endzones at that stadium are covered with artificial turf).^[13] The first stadium to use the next-generation surface was Ottawa's Frank Clair Stadium (now TD Place Stadium), which the Ottawa Renegades used when they began play in 2002. The Saskatchewan Roughriders' Taylor Field was the only major professional sports venue in North America to use a second-generation artificial playing surface, Omniturf, which was used from 1988 to 2000, followed by AstroTurf from 2000 to 2007 and FieldTurf from 2007 to its 2016 closure.^[14]

Cricket

[edit]

Some cricket pitches are made of synthetic grass^[15] or of a hybrid of mostly natural and some artificial grass, with these "hybrid pitches" having been implemented across several parts of the United Kingdom^[16] and Australia.^[17] The first synthetic turf cricket field in the USA was opened in Fremont, California in 2016.^[18]

Field hockey

[edit]

Further information: Field hockey history § The synthetic revolution

The introduction of synthetic surfaces has significantly changed the sport of field hockey. Since being introduced in the 1970s, competitions in western countries are now mostly played on artificial surfaces. This has increased the speed of the game considerably and changed the shape of hockey sticks to allow for different techniques, such as reverse stick trapping and hitting.

Field hockey artificial turf differs from artificial turf for other sports, in that it does not try to reproduce a grass feel, being made of shorter fibers. This allows the improvement in speed brought by earlier artificial turfs to be retained. This development is problematic for areas which cannot afford to build an extra artificial field for hockey alone. The International Hockey Federation and manufacturers are driving research in order to produce new fields that will be suitable for a variety of sports.

The use of artificial turf in conjunction with changes in the game's rules (e.g., the removal of offside, introduction of rolling substitutes and the self-pass, and to the interpretation of obstruction) have contributed significantly to change the nature of the game, greatly increasing the speed and intensity of play as well as placing far greater demands on the conditioning of the players.

Association football

[edit]

Some association football clubs in Europe installed synthetic surfaces in the 1980s, which were called "plastic pitches" (often derisively) in countries such as England. There, four professional club venues had adopted them; Queens Park Rangers's Loftus Road (1981–1988), Luton Town's Kenilworth Road (1985–1991), Oldham Athletic's Boundary Park (1986–1991) and Preston North End's Deepdale (1986–1994). QPR had been the first team to install an artificial pitch at their stadium in 1981, but were the first to remove it when they did so in 1988. Artificial pitches were banned from top-flight (then First Division) football in 1991, forcing Oldham Athletic to remove their artificial pitch after their promotion to the First Division in 1991, while then top-flight Luton Town also removed their artificial pitch at the same time. The last Football League team to have an artificial pitch in England was Preston North End, who removed their pitch in 1994 after eight years in use. Artificial pitches were banned from the top four divisions from 1995.

Artificial turf gained a bad reputation^{[neutrality is disputed]} globally, with fans and especially with players. The first-generation artificial turf surfaces were carpet-like in their look and feel, and thus, a far harder surface than grass and soon became known^{[by whom?]} as an unforgiving playing surface that was prone to cause more injuries, and in particular, more serious joint injuries, than would comparatively be suffered on a grass surface. This turf was also regarded as aesthetically unappealing to many fans^{[weasel words]}.

In 1981, London football club Queens Park Rangers dug up its grass pitch and installed an artificial one. Others followed, and by the mid-1980s there were four artificial surfaces in operation in the English league. They soon became a national joke: the ball pinged round like it was made of rubber, the players kept losing their footing, and anyone who fell over risked carpet burns. Unsurprisingly, fans complained that the football was awful to watch and, one by one, the clubs returned to natural grass.^[19]

In the 1990s, many North American soccer clubs also removed their artificial surfaces and re-installed grass, while others moved to new stadiums with state-of-the-art grass surfaces that were designed to withstand cold temperatures where the climate demanded it. The use of artificial turf was later banned by FIFA, UEFA and by many domestic football associations, though, in recent years,^[when?] both governing bodies have expressed resurrected interest in the use of artificial surfaces in competition, provided that they are FIFA Recommended. UEFA has now been heavily involved in programs to test artificial turf, with tests made in several grounds meeting with FIFA approval. A team of UEFA, FIFA and German company Polytan conducted tests in the Stadion Salzburg Wals-Siezenheim in Salzburg, Austria which had matches played on it in UEFA Euro 2008. It is the second FIFA 2 Star approved artificial turf in a European domestic top flight, after Dutch club Heracles Almelo received the FIFA certificate in August 2005.^[20] The tests were approved.^[21]

FIFA originally launched its FIFA Quality Concept in February 2001. UEFA announced that starting from the 2005–06 season, approved artificial surfaces were to be permitted in their competitions.

A full international fixture for the 2008 European Championships was played on 17 October 2007 between England and Russia on an artificial surface, which was installed to counteract adverse weather conditions, at the Luzhniki Stadium in Moscow.^[22][23] It was one of the first full international games to be played on such a surface approved by FIFA and UEFA. The latter ordered the 2008 European Champions League final hosted in the same stadium in May 2008 to place on grass, so a temporary natural grass field was installed just for the final.

UEFA stressed that artificial turf should only be considered an option where climatic conditions necessitate.^[24] One Desso "hybrid grass" product incorporates both natural grass and artificial elements.^[25]

In June 2009, following a match played at Estadio Ricardo Saprissa in Costa Rica, American national team manager Bob Bradley called on FIFA to "have some courage" and ban artificial surfaces.

FIFA designated a star system for artificial turf fields that have undergone a series of tests that examine quality and performance based on a two star system.^[26] Recommended two-star fields may be used for FIFA Final Round Competitions as well as for UEFA Europa League and Champions League matches.^[27] There are currently 130 FIFA Recommended 2-Star installations in the world.^[28]

In 2009, FIFA launched the Preferred Producer Initiative to improve the quality of artificial football turf at each stage of the life cycle (manufacturing, installation and maintenance).^[29] Currently, there are five manufacturers that were selected by FIFA: Act Global, Limonta, Desso, GreenFields, and Edel Grass. These firms have made quality guarantees directly to FIFA and have agreed to increased research and development.

In 2010, Estadio Omnilife with an artificial turf opened in Guadalajara to be the new home of Chivas, one of the most popular teams in Mexico. The owner of Chivas, Jorge Vergara, defended the reasoning behind using artificial turf because the stadium was designed to be "environment friendly and as such, having grass would result [in] using too much water."^[30] Some players criticized the field, saying its harder surface caused many injuries. When Johan Cruyff became the adviser of the team, he recommended the switch to natural grass, which the team did in 2012.^[31]

In November 2011, it was reported that a number of English football clubs were interested in using artificial pitches again on economic grounds.^[32] As of January 2020, artificial pitches are not permitted in the Premier League or Football League but are permitted in the National League and lower divisions. Bromley are an example of an English football club who currently use a third-generation artificial pitch.^[33] In 2018, Sutton United were close to achieving promotion to the Football League and the debate in England about artificial pitches resurfaced again. It was reported that, if Sutton won promotion, they would subsequently be demoted two leagues if they refused to replace their pitch with natural grass.^[34] After Harrogate Town's promotion to the Football League in 2020, the club was obliged to install a natural grass pitch at Wetherby Road;^[35] and after winning promotion in 2021 Sutton Utd were also obliged to tear up their artificial pitch and replace it with grass, at a cost of more than £500,000.^[36] Artificial pitches are permitted in all rounds of the FA Cup competition.

The 2015 FIFA Women's World Cup took place entirely on artificial surfaces, as the event was played in Canada, where almost all of the country's stadiums use artificial turf due to climate issues. This plan garnered criticism from players and fans, some believing the artificial surfaces make players more susceptible to injuries. Over fifty of the female athletes protested against the use of artificial turf on the basis of gender discrimination.^[37][38] Australia winger Caitlin Foord said that after playing 90 minutes there was no difference to her post-match recovery – a view shared by the rest of the squad. The squad spent much time preparing on the surface and had no problems with its use in Winnipeg. "We've been training on [artificial] turf pretty much all year so I think we're kind of used to it in that way ... I think grass or turf you can still pull up sore after a game so it's definitely about getting the recovery in and getting it right", Foord said.^[39] A lawsuit was filed on 1 October 2014 in an Ontario tribunal court by a group of women's international soccer players against FIFA and the Canadian Soccer Association and specifically points out that in 1994 FIFA spent $2 million to plant natural grass over artificial turf in New Jersey and Detroit.^[40] Various celebrities showed their support for the women soccer players in defense of their lawsuit, including actor Tom Hanks, NBA player Kobe Bryant and U.S. men's soccer team keeper Tim Howard. Even with the possibility of boycotts, FIFA's head of women's competitions, Tatjana Haenni, made it clear that "we play on artificial turf and there's no Plan B."^[41][42]

The first stadium to use artificial turf in Brazil was Atlético Paranaense's Arena da Baixada in 2016. In 2020, the administration of Allianz Parque, home of Sociedade Esportiva Palmeiras, started the implementation of the second artificial pitch in the country.^[43]

Rugby union

[edit]

Rugby union also uses artificial surfaces at a professional level. Infill fields are used by English Premiership Rugby teams Gloucester, Newcastle Falcons, Saracens F.C. and the now defunct Worcester Warriors, as well as United Rugby Championship teams Cardiff, Edinburgh and Glasgow Warriors. Some fields, including Twickenham Stadium, have incorporated a hybrid field, with grass and synthetic fibers used on the surface. This allows for the field to be much more hard wearing, making it less susceptible to weather conditions and frequent use.

Tennis

[edit]

Carpet has been used as a surface for indoor tennis courts for decades, though the first carpets used were more similar to home carpets than a synthetic grass. After the introduction of AstroTurf, it came to be used for tennis courts, both indoor and outdoor, though only a small minority of courts use the surface.^[44][45] Both infill and non-infill versions are used, and are typically considered medium-fast to fast surfaces under the International Tennis Federation's classification scheme.^[44] A distinct form found in tennis is an "artificial clay" surface,^[44] which seeks to simulate a clay court by using a very short pile carpet with an infill of the same loose aggregate used for clay courts that rises above the carpet fibers.^[44]

Tennis courts such as Wimbledon are considering using an artificial hybrid grass to replace their natural lawn courts. Such systems incorporate synthetic fibers into natural grass to create a more durable surface on which to play.^[46] Such hybrid surfaces are currently used for some association football stadiums, including Wembley Stadium.

Synthetic turf can also be used in the golf industry, such as on driving ranges, putting greens and even in some circumstances tee boxes. For low budget courses, particularly those catering to casual golfers, synthetic putting greens offer the advantage of being a relatively cheap alternative to installing and maintaining grass greens, but are much more similar to real grass in appearance and feel compared to sand greens which are the traditional alternative surface. Because of the vast areas of golf courses and the damage from clubs during shots, it is not feasible to surface fairways with artificial turf.

Artificial grass is used to line the perimeter of some sections of some motor circuits, and offers less grip than some other surfaces.^[47] It can pose an obstacle to drivers if it gets caught on their car.^[48]

Since the early 1990s, the use of synthetic grass in the more arid western states of the United States has moved beyond athletic fields to residential and commercial landscaping.^[49] New water saving programs, as of 2019, which grant rebates for turf removal, do not accept artificial turf as replacement and require a minimum of plants.^[50][51]

The use of artificial grass for convenience sometimes faces opposition: Legislation frequently seeks to preserve natural gardens and fully water permeable surfaces, therefore restricting the use of hardscape and plantless areas, including artificial turf. In several locations in different countries, homeowners have been fined, ordered to remove artificial turf and/or had to defend themselves in courts. Many of these restrictions can be found in local bylaws and ordinances. These not always applied in a consistent manner,^[52][53][54] especially in municipalities that utilize a complaint-based model for enforcing local laws.

Sunlight reflections from nearby windows can cause artificial turf to melt. This can be avoided by adding perforated vinyl privacy window film adhesive to the outside of the window causing the reflection.

Artificial turf has been used at airports.^[55] Here it provides several advantages over natural turf – it does not support wildlife, it has high visual contrast with runways in all seasons, it reduces foreign object damage (FOD) since the surface has no rocks or clumps, and it drains well.^[56]

Some artificial turf systems allow for the integration of fiber-optic fibers into the turf. This would allow for runway lighting to be embedded in artificial landing surfaces for aircraft (or lighting or advertisements to be directly embedded in a playing surface).^[57]

Artificial turf is commonly used for tanks containing octopusses, in particular the Giant Pacific octopus since it is a reliable way to prevent the octopusses from escaping their tank, as they prevent the suction cups on the tentacles from getting a tight seal.^[58]

The first major academic review of the environmental and health risks and benefits of artificial turf was published in 2014;^[59] it was followed by extensive research on possible risks to human health, but holistic analyses of the environmental footprint of artificial turf compared with natural turf only began to emerge in the 2020s,^[60][61] and frameworks to support informed policymaking were still lacking.^[62][63] Evaluating the relative environmental footprints of natural and artificial turf is complex, with outcomes depending on a wide range of factors, including (to give the example of a sports field):^[59]

• what ecosystem services are lost by converting a site to a sports pitch
• how resource-intensive is the landscaping work and transport of materials to create a pitch
• whether input materials are recycled and whether these are recycled again at the end of the pitch's life
• how resource-intensive and damaging maintenance is (whether through water, fertiliser, weed-killer, reapplication of rubber crumb, snow-clearing, etc.)
• how intensively the facility is used, for how long, and whether surface type can reduce the overall number of pitches required

Artificial turf has been shown to contribute to global warming by absorbing significantly more radiation than living turf and, to a lesser extent, by displacing living plants that could sequester carbon dioxide through photosynthesis;^[64] a study at New Mexico State University found that in that environment, water-cooling of artificial turf can demand as much water as natural turf.^[65] However, a 2022 study that used real-world data to model a ten-year-life-cycle environmental footprint for a new natural-turf soccer field compared with an artificial-turf field found that the natural-turf field contributed twice as much to global warming as the artificial one (largely due to a more resource-intensive construction phase), while finding that the artificial turf would likely cause more pollution of other kinds. It promoted improvements to usual practice such as the substitution of cork for rubber in artificial pitches and more drought-resistant grasses and electric mowing in natural ones.^[60] In 2021, a Zurich University of Applied Sciences study for the city of Zurich, using local data on extant pitches, found that, per hour of use, natural turf had the lowest environmental footprint, followed by artificial turf with no infill, and then artificial turf using an infill (e.g. granulated rubber). However, because it could tolerate more hours of use, unfilled artificial turf often had the lowest environmental footprint in practice, by reducing the total number of pitches required. The study recommended optimising the use of existing pitches before building new ones, and choosing the best surface for the likely intensity of use.^[61] Another suggestion is the introduction of green roofs to offset the conversion of grassland to artificial turf.^[66]

Contrary to popular belief, artificial turf is not maintenance free. It requires regular maintenance, such as raking and patching, to keep it functional and safe.^[67]

Some artificial turf uses infill such as silicon sand, but most uses granulated rubber, referred to as "crumb rubber". Granulated rubber can be made from recycled car tires and may carry heavy metals, PFAS chemicals, and other chemicals of environmental concern. The synthetic fibers of artificial turf are also subject to degradation. Thus chemicals from artificial turfs leach into the environment, and artificial turf is a source of microplastics pollution and rubber pollution in air, fresh-water, sea and soil environments.^{[68][69][70][71][72][73][59][excessive citations]} In Norway, Sweden, and at least some other places, the rubber granulate from artificial turf infill constitutes the second largest source of microplastics in the environment after the tire and road wear particles that make up a large portion of the fine road debris.^[74][75][76] As early as 2007, Environment and Human Health, Inc., a lobby-group, proposed a moratorium on the use of ground-up rubber tires in fields and playgrounds based on health concerns;^[77] in September 2022, the European Commission made a draft proposal to restrict the use of microplastic granules as infill in sports fields.^[78]

What is less clear is how likely this pollution is in practice to harm humans or other organisms and whether these environmental costs outweigh the benefits of artificial turf, with many scientific papers and government agencies (such as the United States Environmental Protection Agency) calling for more research.^[2] A 2018 study published in Water, Air, & Soil Pollution analyzed the chemicals found in samples of tire crumbs, some used to install school athletic fields, and identified 92 chemicals only about half of which had ever been studied for their health effects and some of which are known to be carcinogenic or irritants. It stated "caution would argue against use of these materials where human exposure is likely, and this is especially true for playgrounds and athletic playing fields where young people may be affected".^[79] Conversely, a 2017 study in Sports Medicine argued that "regular physical activity during adolescence and early adulthood helps prevent cancer later in life. Restricting the use or availability of all-weather year-round synthetic fields and thereby potentially reducing exercise could, in the long run, actually increase cancer incidence, as well as cardiovascular disease and other chronic illnesses."^[80]

The possibility that carcinogenic substances in artificial turf could increase risks of human cancer (the artificial turf–cancer hypothesis) gained a particularly high profile in the first decades of the twenty-first century and attracted extensive study, with scientific reports around 2020 finding cancer-risks in modern artificial turf negligible.^{[81][82][83][84]} But concerns have extended to other human-health risks, such as endocrine disruption that might affect early puberty, obesity, and children's attention spans.^{[85][86][87][88]} Potential harm to fish^[70] and earthworm^[89] populations has also been shown.

A study for the New Jersey Department of Environmental Protection analyzed lead and other metals in dust kicked into the air by physical activity on five artificial turf fields. The results suggest that even low levels of activity on the field can cause particulate matter containing these chemicals to get into the air where it can be inhaled and be harmful. The authors state that since no level of lead exposure is considered safe for children, "only a comprehensive mandated testing of fields can provide assurance that no health hazard on these fields exists from lead or other metals used in their construction and maintenance."^[90]

A number of health and safety concerns have been raised about artificial turf.^[2] Friction between skin and older generations of artificial turf can cause abrasions and/or burns to a much greater extent than natural grass.^[91] Artificial turf tends to retain heat from the sun and can be much hotter than natural grass with prolonged exposure to the sun.^[92]

There is some evidence that periodic disinfection of artificial turf is required as pathogens are not broken down by natural processes in the same manner as natural grass. Despite this, a 2006 study suggests certain microbial life is less active in artificial turf.^[91]

There is evidence showing higher rates of player injury on artificial turf. By November 1971, the injury toll on first-generation artificial turf had reached a threshold that resulted in congressional hearings by the House subcommittee on commerce and finance.^[93][94][95] In a study performed by the National Football League Injury and Safety Panel, published in the October 2012 issue of the American Journal of Sports Medicine, Elliott B. Hershman et al. reviewed injury data from NFL games played between 2000 and 2009, finding that "the injury rate of knee sprains as a whole was 22% higher on FieldTurf than on natural grass. While MCL sprains did not occur at a rate significantly higher than on grass, rates of ACL sprains were 67% higher on FieldTurf."^[96] Metatarsophalangeal joint sprain, known as "turf toe" when the big toe is involved, is named from the injury being associated with playing sports on rigid surfaces such as artificial turf and is a fairly common injury among professional American football players. Artificial turf is a harder surface than grass and does not have much "give" when forces are placed on it.^[97]
