Sustainable gardening includes the more specific sustainable landscapes, sustainable landscape design, sustainable landscaping, sustainable landscape architecture, resulting in sustainable sites. It comprises a disparate group of horticultural interests that can share the aims and objectives associated with the international post-1980s sustainable development and sustainability programs developed to address that humans are now using natural biophysical resources faster than they can be replenished by nature.

Included within this are those home gardeners, and members of the landscape and nursery industries, and municipal authorities, that integrate environmental, social, and economic factors to create a more sustainable future. Benefits of sustainable gardening also include improved access to fresh foods and biodiversity in cities. [1]

Sustainable Sites Initiative

The Sustainable Sites Initiative is a commercial accreditation body in USA which certifies landscapers and sites using guidelines and performance benchmarks for sustainable land design, for which their registered trademark can be earned after a fee. [2] It was founded in 2005. Using the United Nations Brundtland Report’s definition of sustainable development as a model, it defines sustainability as: [2]

...design, construction, operations and maintenance practices that meet the needs of the present without compromising the ability of future generations to meet their own needs

by attempting to:

...protect, restore and enhance the ability of landscapes to provide ecosystem services that benefit humans and other organisms.

There is no uniform national standard for a sustainable landscaping project in the USA. [2] Sites are rated according to their impact on ecosystem services: [2] The following ecosystem services have been identified:


Principles

Enhancement of ecosystem services is encouraged throughout the life of any site by providing clear design, construction and management criteria. [2] Sustainability requires that environmental, social and economic demands are integrated. Guidelines supplement existing green building guidelines and include metrics (benchmarks, audits, criteria, indexes etc.) that give some measure of sustainability (a rating system) by clarifying what is sustainable or not sustainable or, more likely, what is more or less sustainable. [2]

Impacts of a site can be assessed and measured over any spatio-temporal scale. Impacts of a site may be direct by having direct measurable impacts on biodiversity and ecology at the site itself, or indirect when impacts occur away from the site.

One major feature distinguishing sustainable gardens, landscapes and sites from other similar enterprises is the quantification of site sustainability by establishing performance benchmarks. Because sustainability is such a broad concept the environmental impacts of sites can be categorised in numerous ways depending on the purpose for which the figures are required. The process can include minimising negative environmental impacts and maximising positive impacts. As currently applied the environment is usually given priority over social and economic factors which may be added in or regarded as an inevitable and integral part of the management process. A home gardener is likely to use simpler metrics than a professional landscaper.

Three methods for measuring site sustainability include BREEAM developed by the BRE organisation in the UK, Leed, developed in America and the Oxford 360 degree sustainability Index used in Oxford Park and developed by the Oxford Sustainable Group in Scandinavia.[ citation needed ]

Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. Land use by humans has a long history, first emerging more than 10,000 years ago. It has been defined as "the purposes and activities through which people interact with land and terrestrial ecosystems" and as "the total of arrangements, activities, and inputs that people undertake in a certain land type." Land use is one of the most important drivers of global environmental change.

Energy-efficient landscaping is a type of landscaping designed for the purpose of conserving energy. There is a distinction between the embedded energy of materials and constructing the landscape, and the energy consumed by the maintenance and operations of a landscape.

<span class="mw-page-title-main">Landscape architecture</span> 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. 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.

<span class="mw-page-title-main">Green roof</span> Roof that is covered with vegetation and a growing substrate

A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. It may also include additional layers such as a root barrier and drainage and irrigation systems. Container gardens on roofs, where plants are maintained in pots, are not generally considered to be true green roofs, although this is debated. Rooftop ponds are another form of green roofs which are used to treat greywater. Vegetation, soil, drainage layer, roof barrier and irrigation system constitute green roof.

Land development is the alteration of landscape in any number of ways such as:

<span class="mw-page-title-main">Environmental planning</span> Considering environment in developing land

Environmental planning is the process of facilitating decision making to carry out land development with the consideration given to the natural environment, social, political, economic and governance factors and provides a holistic framework to achieve sustainable outcomes. A major goal of environmental planning is to create sustainable communities, which aim to conserve and protect undeveloped land.

<span class="mw-page-title-main">Sustainable city</span> City designed with consideration for social, economic, environmental impact

A sustainable city, eco-city, or green city is a city designed with consideration for social, economic, environmental impact, and resilient habitat for existing populations, without compromising the ability of future generations to experience the same. The UN Sustainable Development Goal 11 defines sustainable cities as those that are dedicated to achieving green sustainability, social sustainability and economic sustainability. They are committed to doing so by enabling opportunities for all through a design focused on inclusivity as well as maintaining a sustainable economic growth. The focus will also includes minimizing required inputs of energy, water, and food, and drastically reducing waste, output of heat, air pollution – CO2, methane, and water pollution. Richard Register, a visual artist, first coined the term ecocity in his 1987 book Ecocity Berkeley: Building Cities for a Healthy Future, where he offers innovative city planning solutions that would work anywhere. Other leading figures who envisioned sustainable cities are architect Paul F Downton, who later founded the company Ecopolis Pty Ltd, as well as authors Timothy Beatley and Steffen Lehmann, who have written extensively on the subject. The field of industrial ecology is sometimes used in planning these cities.

<span class="mw-page-title-main">Sustainable drainage system</span>

Sustainable drainage systems are a collection of water management practices that aim to align modern drainage systems with natural water processes and are part of a larger green infrastructure strategy. SuDS efforts make urban drainage systems more compatible with components of the natural water cycle such as storm surge overflows, soil percolation, and bio-filtration. These efforts hope to mitigate the effect human development has had or may have on the natural water cycle, particularly surface runoff and water pollution trends.

<span class="mw-page-title-main">Conservation development</span> Controlled-growth land use development

Conservation development, also known as conservation design, is a controlled-growth land use development that adopts the principle for allowing limited sustainable development while protecting the area's natural environmental features in perpetuity, including preserving open space landscape and vista, protecting farmland or natural habitats for wildlife, and maintaining the character of rural communities. A conservation development is usually defined as a project that dedicates a minimum of 50 percent of the total development parcel as open space. The management and ownership of the land are often formed by the partnership between private land owners, land-use conservation organizations and local government. It is a growing trend in many parts of the country, particularly in the Western United States. In the Eastern United States, conservation design has been promoted by some state and local governments as a technique to help preserve water quality.

<span class="mw-page-title-main">Green infrastructure</span> Sustainable and resilient infrastructure

Green infrastructure or blue-green infrastructure refers to a network that provides the “ingredients” for solving urban and climatic challenges by building with nature. The main components of this approach include stormwater management, climate adaptation, the reduction of heat stress, increasing biodiversity, food production, better air quality, sustainable energy production, clean water, and healthy soils, as well as more anthropocentric functions, such as increased quality of life through recreation and the provision of shade and shelter in and around towns and cities. Green infrastructure also serves to provide an ecological framework for social, economic, and environmental health of the surroundings. More recently scholars and activists have also called for green infrastructure that promotes social inclusion and equity rather than reinforcing pre-existing structures of unequal access to nature-based services.

<span class="mw-page-title-main">Ecological design</span> Design approach sensitive to environmental impacts

Ecological design or ecodesign is an approach to designing products and services that gives special consideration to the environmental impacts of a product over its entire lifecycle. Sim Van der Ryn and Stuart Cowan define it as "any form of design that minimizes environmentally destructive impacts by integrating itself with living processes." Ecological design can also be defined as the process of integrating environmental considerations into design and development with the aim of reducing environmental impacts of products through their life cycle.

<span class="mw-page-title-main">Xeriscaping</span> Water conserving landscaping method

Xeriscaping is the process of landscaping, or gardening, that reduces or eliminates the need for irrigation. It is promoted in regions that do not have accessible, plentiful, or reliable supplies of fresh water and has gained acceptance in other regions as access to irrigation water has become limited, though it is not limited to such climates. Xeriscaping may be an alternative to various types of traditional gardening.

Sustainable landscaping is a modern type of gardening or landscaping that takes the environmental issue of sustainability into account. According to Loehrlein in 2009 this includes design, construction and management of residential and commercial gardens and incorporates organic lawn management and organic gardening techniques.

Environmentally sustainable design is the philosophy of designing physical objects, the built environment, and services to comply with the principles of ecological sustainability and also aimed at improving the health and comfort of occupants in a building. Sustainable design seeks to reduce negative impacts on the environment, the health and well-being of building occupants, thereby improving building performance. The basic objectives of sustainability are to reduce the consumption of non-renewable resources, minimize waste, and create healthy, productive environments.

<span class="mw-page-title-main">Foodscaping</span> Ornamental landscaping with edible plants

Foodscaping is a modern term for the practice of integrating edible plants into ornamental landscapes. It is also referred to as edible landscaping and has been described as a crossbreed between landscaping and farming. As an ideology, foodscaping aims to show that edible plants are not only consumable but can also be appreciated for their aesthetic qualities. Foodscaping spaces are seen as multi-functional landscapes which are visually attractive and also provide edible returns. Foodscaping is a great way to provide fresh food in an affordable way.
