Greening

Last updated

Greening is the process of transforming living environments, and also artifacts such as a space, a lifestyle or a brand image, into a more environmentally friendly version (i.e. 'greening your home' or 'greening your office'). The act of greening generally involves incorporating more environmentally friendly systems into one's environment, such as the home, work place, and general lifestyle. [1]

Greening is also a general term for the appropriate selection and planting of plants on, in, or next to buildings and in public parks. The goal of greening is usually a combination of environmental benefits and improving the visual design of surfaces, for example, a green wall or green roof, as well as the creation of green spaces. This usually requires technical measures such as earthworks or supporting climbing plants. Furthermore, permanent care and irrigation is usually necessary to maintain the greened environment. In some areas there are normative requirements for the planning and execution of the greening, for example roadsides greening. In soil bioengineering, plants with technical functions may be needed.

Measures such as the recultivation of heaps, plantations as part of a compensatory measure or, in tiller forestry, the planting of vegetation are distinguished from greening. In professional parlance, the sowing or planting of agricultural crops is also referred to as crop growing or occasionally as field cultivation. The term sowing is used for lawns.

The greening of deserts is a particularly difficult task. If it is sustainable, it is the most effective measure for the economic development of arid areas, decreases global warming, and also improves the local climate. The state of Israel in Negev has long been a pioneer in this field. A project between 1991 and 2011 and supported by, among others, the forests of German states provided 450,000 trees for the desert city of Beersheba. Another major reforestation (greening) project is China's Green Wall, which aims to reduce the increasing devastation of entire regions in the north and west of the People's Republic of China.

Green qualities

These "green" qualities include, but are not limited to:

Assessment

Environmentally friendly companies such as Green Home have developed a rigorous approval policy that allows consumers to qualify each product based upon these criteria as they apply to specific product categories. [2]

Health benefits of greening

Exposure to greening initiatives has proven to achieve great health benefits for people of all ages. [3] Greening can alleviate stressors of an urban environment, providing more opportunities to experience tranquility, reduce noise, and induce cooling effects. [4] Exposure to greening initiatives can benefit both physical and mental health and can lead to more environmental awareness. Greening includes habitat restoration, planting trees, food gardening and naturalization. [5]

Health benefits of greening in schools

Children have been a particular focus in this area of research due to the increasingly limited access to green spaces and nature. [5] In urban areas, parents or guardians may favor playing indoors versus outdoors based on the perception of safety and concerns. [6] For example, families who live farther away from green spaces are more likely to push for indoor activities because of close proximity to busy roads or construction sites. On average, children in the United States spend about 1,000 hours a year in school. [7] Therefore, schools are an excellent tool for greening initiatives that involve children in urban spaces.

Habitat restoration, gardening, naturalization and rewilding efforts in schools provide children with the opportunity to connect with nature. In a study conducted in Finland, researchers found that adding green to the school yard increased passion for outdoor activity as well as creativity and spontaneity in 3 to 5 year old children. [5] In Barcelona, Spain, school greening initiatives provided more opportunities for children to spend time outside and reduced inequities in residential access. [6] In current efforts to limit exposure to COVID-19 and contact between individuals, school yards have become an even more important tool to promote social learning and education. [8] Benefits of greening initiatives include electricity cost savings due to cooling technology of greening, improving the environment, providing healthy educational space, and more learning opportunities. It can help alleviate the stressors associated with urban climates and benefit both mental and physical health of children.

Greening schoolyards

Schools increase the total green space by adding green oases in yards and replacing pavement with vegetation. In Paris, schools have adopted this intervention as a cooling program for schools. Chicago’s Department of Water Management and the Metropolitan Water Reclamation District of Greater Chicago implemented a greening initiative called The Space to Grow. [9] Though the purpose of this initiative was to control flooding and stormwater, schools successfully replaced asphalt with green space because of generous program funding by the city.

Green roofs

Installing green roofs on schools is an alternative way of increasing green space access for children, especially in urban areas. The United States is currently seeing efforts by political figures to increase awareness and funding in greening. For example, U.S Rep. Nydia M, Velazquez (D-NY) introduced a bill that would allocate $500 million federal funds to plan, install and maintain green roofs at public schools in New York City. [10] It would be overseen by the U.S. Department of Energy through a grant program.

Gardens

Gardens are a unique greening initiative, whether the goal is to grow vegetables, fruit or flowers. For example, in Brookline, Massachusetts (United States), the Florida Riffin Ridley School has a vegetable garden that is maintained by teachers, students and parents. A garden intervention may positively influence children’s food preference, increase intake of fruits and vegetables, and increase physical activity. [11]

Greenery Office

Plants can be added to offices and workspaces to aid in focus, reduce stress levels, increase creativity, improve air quality, and provide aesthetic appeal.

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.

Urban forestry advocates the role of trees as a critical part of the urban infrastructure. Urban foresters plant and maintain trees, support appropriate tree and forest preservation, conduct research and promote the many benefits trees provide. Urban forestry is practiced by municipal and commercial arborists, municipal and utility foresters, environmental policymakers, city planners, consultants, educators, researchers and community activists.

<span class="mw-page-title-main">Community gardening</span> Type of horticulture and food production

A community garden is a piece of land gardened or cultivated by a group of people individually or collectively. Normally in community gardens, the land is divided into individual plots. Each individual gardener is responsible for their own plot and the yielding or the production of which belongs to the individual. In collective gardens the piece of land is not divided. A group of people cultivate it together and the harvest belongs to all participants. Around the world, community gardens exist in various forms, it can be located in the proximity of neighborhoods or on balconies and rooftops. Its size can vary greatly from one to another.

Over the centuries the roles of rivers as part of the city has altered many times from the original use for the irrigating crops in nearby fields, as well as being an essential resource in establishing a permanent settlement. However, when the industrial revolution took place in the 19th century the role of the rivers in cities altered and it became a far more valuable resource as it allowed not only for the transportation of goods from town to town but also became the basis for the expansion and improvement of the trading prowess of the city. This transportation of goods was done through the construction of a canal network spreading across the country which tamed the rivers sufficiently and so therefore allowed for the movement of goods such as coal to move from place to place. Furthermore, after the advancement of the railway network which now took over most of the movement of goods throughout the country, this left the rivers and canals of Britain without a role in Britain’s transport network. This allowed areas of the canal and river networks to become polluted through chemical waste and public misuse, which caused difficulties for the animals for which the river and its surrounding wetlands and marshes were their natural habitats. Yet since the 1950s there has been a dramatic increase in the number of riverside developments which have not only brought increased money into the area but have also redeveloped and enhanced the natural environment and increased the aesthetic qualities of these areas on the whole.

<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 equality rather than reinforcing pre-existing structures of unequal access to nature-based services.

<span class="mw-page-title-main">Urban green space</span> Green area planned in an urban location

In land-use planning, urban green space is open-space areas reserved for parks and other "green spaces", including plant life, water features - also referred to as blue spaces - and other kinds of natural environment. Most urban open spaces are green spaces, but occasionally include other kinds of open areas. The landscape of urban open spaces can range from playing fields to highly maintained environments to relatively natural landscapes.

The compact city or city of short distances is an urban planning and urban design concept, which promotes relatively high residential density with mixed land uses. It is based on an efficient public transport system and has an urban layout which – according to its advocates – encourages walking and cycling, low energy consumption and reduced pollution. A large resident population provides opportunities for social interaction as well as a feeling of safety in numbers and "eyes on the street". It is also arguably a more sustainable urban settlement type than urban sprawl because it is less dependent on the car, requiring less infrastructure provision.

<span class="mw-page-title-main">Community gardening in the United States</span>

Community gardens in the United States benefit both gardeners and society at large. Community gardens provide fresh produce to gardeners and their friends and neighbors. They provide a place of connection to nature and to other people. In a wider sense, community gardens provide green space, a habitat for insects and animals, sites for gardening education, and beautification of the local area. Community gardens provide access to land to those who otherwise could not have a garden, such as apartment-dwellers, the elderly, and the homeless. Many gardens resemble European allotment gardens, with plots or boxes where individuals and families can grow vegetables and flowers, including a number which began as victory gardens during World War II. Other gardens are worked as community farms with no individual plots at all, similar to urban farms.

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.

<span class="mw-page-title-main">Open space accessibility in California</span>

Open spaces in urban environments, such as parks, playgrounds, and natural areas, can provide many health, cultural, recreational, and economic benefits to the communities nearby. However, access to open spaces can be unequal for people of different incomes. In California's two largest metropolitan regions, Los Angeles County in Southern California and the Bay Area in Northern California, access to green space and natural areas varies with the predominant races and classes of the communities. This also holds true in San Diego County in Southern California. Both expanding urbanization and diminishing funding for open space tend to widen these gaps in accessibility. Because open space is associated with various mental and physical benefits, a lack of access to it can pose health consequences. However, more research is needed to determine whether such environmental inequalities translate into long-term health inequalities, and, if so, how.

<span class="mw-page-title-main">Biophilic design</span> Building industry concept

Biophilic design is a concept used within the building industry to increase occupant connectivity to the natural environment through the use of direct nature, indirect nature, and space and place conditions. Used at both the building and city-scale, it is argued that this idea has health, environmental, and economic benefits for building occupants and urban environments, with few drawbacks. Although its name was coined in recent history, indicators of biophilic design have been seen in architecture from as far back as the Hanging Gardens of Babylon.

Urban agriculture is the practice of cultivating, processing, and distributing food in or around urban areas. It is the growing of fresh produce within the city for individual, communal, or commercial purposes in cities in both developed and developing countries.
