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.

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]}

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]

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]

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]

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]

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]

A backyard, or back yard (known in the United Kingdom as a back garden or just garden), is a yard at the back of a house, common in suburban developments in the Western world.^[1]

It is typically residential garden located at the rear of a property, on the other side of the house from the front yard. While Western gardens are almost universally based on plants, the "garden" (which etymologically may imply a shorthand of botanical garden) may use plants sparsely or not at all. Hence, the terms yard and garden are for the context of this article interchangeable in most cases.

In English suburban and gardening culture, back gardens have a special place.^[2] In Britain there are over 10 million back gardens.^[3] British planning require minimum distances between the rear faces of adjacent dwellings and so there is usually space for a back garden of some sort. In other countries, such as Australia, this does not apply and preference for buildings with a large footprint has tended to squeeze out the space at the rear.^[4]

In Australia, until the mid-20th century, the back yard of a property would traditionally contain a fowl run, outhouse ("dunny"), vegetable patch, and woodheap. More recently, these have been replaced by outdoor entertainments such as a barbecue and swimming pool.^[5] But, since the 1990s, the trend in Australian suburban development has been for back yards to disappear as the dwellings now occupy almost all of the building plot.^[1]

In higher latitudes, it is economical in low land value regions to use open land surrounding a house for vegetable gardening during summers and allow sunlight to enter house windows from a low horizon angle during winters. As land value increases, houses are built nearer to each other. In order to preserve some of the open land, house owners may choose to allow construction on the side land of their houses, but not build in front of or behind their house in order to preserve some remnants of open surrounding land. The back area is known as the backyard or back garden.

A back garden arises when the main building divides the surrounding gardens into two. This happens especially in the high density housing of British cities and towns. A semi-detached house typical of the British suburbs of the 20th century will have front gardens which face the road and provide access. The back gardens in such cases will be more secluded and access will typically be via the dwelling or by a path around the side. A front garden is a formal and semi-public space and so subject to the constraints of convention and law. However, the back garden is more private and casual,^[6] and so can be put to more purposes.

If the housing is terraced, then no side path is possible and access may be provided by an alley which runs behind the rear of the terrace. While buildings opening directly onto a street may not have a front garden, most will have some space at the back, however small; the exception being back-to-back houses found in northern industrial towns in England such as Leeds, but now mostly demolished. A private back yard with a "privy" (toilet) was a defining feature of the byelaw terraced house, a type of dwelling built to comply with the Public Health Act 1875.

Because of weather constraints, it is usual to use a garden more in the summer than in the winter, although some usages are traditional, such as for a bonfire on Bonfire Night, 5 November. Similarly, daytime usage is more common than nighttime.

Functionally, it may be used for:

• Growing food^[3]
• Playing games
• Relaxing and sunbathing
• Raising plants
• Housing pets
• Drying clothes
• Making a compost heap
• Hobbies
• Locating a greenhouse, conservatory, shed, workshop, outhouse, or garage (if access to a road is possible)
• Partying
• Wildlife refuge
• Safe area for children
• Location of an air raid shelter such as the Anderson shelter of World War II^[7]

In fact, its functional and recreational use is so varied, that it cannot be easily categorised. Many of the freedoms of the use of the back garden come from the restrictions, social or legal of what are not done in the front.

Usually, clothes are not dried, vegetables are not grown, and sunbathing is not carried out in a front garden. All these can happen in the privacy of the back garden.

Traditionally, people treat a back garden as private to themselves, and not those they are neighbours to. The social etiquette of how one can greet and interact one's neighbours may be complex and defined by many informal social rules.

In some areas, talking to one's neighbours over the back wall (the side wall following the property boundary line) is usual, and is a welcome form of neighbourliness, while in other places it is not.

Depending on the size of the backyard, it may have any number of items (or none), such as:

• 
  Back yard of a house in Harvey, Louisiana, United States
• 
  A playground being built for a homeowner's backyard as part of a handyman project
• 
  People posing at a backyard party in Canada
•

Landscaping refers to any activity that modifies the visible features of an area of land, including the following:

1. Living elements, such as flora or fauna; or what is commonly called gardening, the art and craft of growing plants with a goal of creating a beauty within the landscape.
2. Natural abiotic elements, such as landforms, terrain shape and elevation, or bodies of water.
3. Abstract elements, such as the weather and lighting conditions.

Landscaping requires a certain understanding of horticulture and artistic design, but is not limited to plants and horticulture. Sculpting land to enhance usability (patio, walkways, ponds, water features) are also examples of landscaping being used. When intended as purely an aesthetic change, the term Ornamental Landscaping is used.^[1]

Often, designers refer to landscaping as an extension of rooms in your house (each one has a function). Outdoor spaces have a vast amount of flexibility as far as materials and function. It is often said the only limitation to outdoor space is one's imagination.

Construction requires both study and observation, and the process varies in different parts of the world. Landscaping varies according to different regions.^[2] Therefore, normally local natural experts are recommended if it is done for the first time. Understanding of the site is one of the chief essentials for successful landscaping.^[3] Different natural features and phenomena, like the position of the sun, terrain, topography, soil qualities, prevailing winds, depth of the frost line, and the system of native flora and fauna must be taken into account.^[4] Sometimes the land is not fit for landscaping. In order to landscape it, the land must be reshaped to direct water for appropriate drainage. This reshaping of land is called grading.^[4] Sometimes in large landscaping projects like, parks, sports fields and reserves soil may need to be improved by adding nutrients for growth of plants or turf, this process is called soil amelioration.^[5]

Removal of earth from the land is called cutting while when earth is added to the slope, it is called filling. Sometimes the grading process may involve removal of excessive waste (landfills), soil and rocks, so designers should take into account while in the planning stage.^[6][7]

At the start, the landscaping contractor issues a statement which is a rough design and layout of what could be done with the land in order to achieve the desired outcome.^[4] Different pencils are required to make graphics of the picture. Landscaping has become more technological than natural, as few projects begin without bulldozers, lawnmowers, or chainsaws.^[2] Different areas have different qualities of plants. When growing new grass, it should ideally be done in the spring and the fall seasons to maximize growth and to minimize the spread of weeds. It is generally agreed that organic or chemical fertilizers are required for good plant growth. Some landscapers prefer to use mix gravel with rocks of varying sizes to add interest in large areas.^[8]
