The Info List - Green Belt

--- Advertisement ---

A green belt or greenbelt is a policy and land use designation used in land use planning to retain areas of largely undeveloped, wild, or agricultural land surrounding or neighbouring urban areas. Similar concepts are greenways or green wedges which have a linear character and may run through an urban area instead of around it. In essence, a green belt is an invisible line designating a border around a certain area, preventing development of the area and allowing wildlife to return and be established.

In those countries which have them, the stated objectives of green belt policy are to:

Protect natural or semi-natural environments; Improve air quality within urban areas; Ensure that urban dwellers have access to countryside, with consequent educational and recreational opportunities; and Protect the unique character of rural communities that might otherwise be absorbed by expanding suburbs.

The green belt has many benefits for people:

Walking, camping, and biking areas close to the cities and towns. Contiguous habitat network for wild plants, animals and wildlife. Cleaner air and water Better land use of areas within the bordering cities.

The effectiveness of green belts differs depending on location and country. They can often be eroded by urban rural fringe uses and sometimes, development 'jumps' over the green belt area, resulting in the creation of "satellite towns" which, although separated from the city by green belt, function more like suburbs than independent communities. History[edit] The Old Testament
Old Testament
outlines a proposal for a green belt around the Levite towns in the Land of Israel.[1] Moses Maimonides
expounded that the greenbelt plan from the Old Testament
Old Testament
referred to all towns in ancient Israel.[2] In the 7th century, Muhammad
established a green belt around Medina. He did this by prohibiting any further removal of trees in a 12-mile long strip around the city.[3] In 1580 Elizabeth I of England banned new building in a 3-mile wide belt around the City of London in an attempt to stop the spread of plague. However, this was not widely enforced and it was possible to buy dispensations which reduced the effectiveness of the proclamation.[4] In modern times, the term emerged from continental Europe where broad boulevards were increasingly used to separate new development from the centre of historic towns; most notably the Ringstraße
in Vienna. Green belt
Green belt
policy was then pioneered in the United Kingdom. Various proposals were put forward from 1890 onwards but the first to garner widespread support was put forward by the London Society
London Society
in its "Development Plan of Greater London" 1919. Alongside the CPRE they lobbied for a continuous belt (of up to two miles wide) to prevent urban sprawl, beyond which new development could occur. There are fourteen green belt areas, in the UK covering 16,716 km², or 13% of England, and 164 km² of Scotland; for a detailed discussion of these, see Green belt
Green belt
(UK). Other notable examples are the Ottawa
Greenbelt and Golden Horseshoe Greenbelt[5] in Ontario, Canada. Ottawa's 20,350 hectare greenbelt is managed by the National Capital Commission
National Capital Commission
(NCC).[6] The more general term in the United States
United States
is green space or greenspace, which may be a very small area such as a park. The dynamic Adelaide
Lands, measuring approximately 7.6 km², completely surround the city centre of Adelaide. On the fringe of the eastern suburbs, an expansive natural greenbelt in the Adelaide
Hills acts as a growth boundary for Adelaide, cooling the region in the hottest months. The concept of "green belt" has evolved in recent years to encompass not only "Greenspace" but also "Greenstructure", taking into account all urban greenspaces, an important aspect of sustainable development in the 21st century. The European Commission's COST
Action C11 (COST – European Cooperation in Science and Technology) is undertaking "Case studies in Greenstructure Planning" involving 15 European countries. An act of the Swedish parliament from 1994 has declared a series of parks in Stockholm
and the adjacent municipality of Solna to its north a "national city park" called Royal National City Park. Criticism[edit] House prices[edit] The difference/contrarian interpretation of the green belt's effects/motivation (for example, suggested by economist Tim Harford[7]) is that a green belt is created by residents to preserve the bourgeois status quo of those already living within the zone, and especially the advantage of landlords who profit from a scarcity of housing (see above, "preserving the character of rural communities"). The stated motivation and benefits of the green belt might be well-intentioned (public health, environment), but these benefits do not accrue as intentioned or claimed (for example, critics such as Mark Pennington[8] claim that only a small fraction of the population ever sets foot on the green belt for leisure purposes, and they claim that a green belt is not strongly causally linked to clean air and water). Rather, the ultimate result of the decision to green-belt a city is to prevent housing demand within the zone to be met with supply,[8] thus exacerbating high housing prices and stifling competitive forces in general. Increasing urban sprawl[edit] Another area of criticism comes from the fact that, since a greenbelt does not extend indefinitely outside a city, it spurs the growth of areas much further away from the city core than if it had not existed, thereby actually increasing urban sprawl.[9] Examples commonly cited are the Ottawa
suburbs of Kanata and Orleans, both of which are outside the city's greenbelt, and are currently undergoing explosive growth (see Greenbelt (Ottawa)). This leads to other problems, as residents of these areas have a longer commute to work places in the city and worse access to public transport. It also means people have to commute through the green belt, an area not designed to cope with high levels of transportation. Not only is the merit of a green beltted, but the green belt may heighten the problem and make the city unsustainable. There are many examples whereby the actual effect of green belts is to act as a land reserve for future freeways and other highways. Examples include sections of the 407 highway north of Toronto and the Hunt Club Rd./Richmond Rd. south of Ottawa. Whether they are originally planned as such, or the result of a newer administration taking advantage of land that was left available by its predecessors is debatable.

(United Kingdom) In the UK, greenbelt barriers to urban expansion have been criticized as one of several protectionist political-economic barriers to housebuilding with negative effects on the supply, cost/prices, and quality of new homes. Critics argue that the greenbelts defeat their own stated objective of saving the countryside and open spaces. By preventing existing towns and cities from extending normally and organically, they result in more land-extensive housing developments further out – i.e., the establishment beyond the greenbelts of new communities with lower building densities, their own built infrastructure and other facilities, and greater dependence on cars and commuting, etc. Meanwhile, valuable urban green space and brownfield sites best suited to industry and commerce are lost in existing conurbations as more and more new housing is crammed into them.[10] Notable examples[edit] Australia[edit]

Adelaide's Central Business District is completely encircled by the Adelaide
Parklands, as was initially planned in 1837. The Nillumbik Shire Council which is located approximately 30 km (19 miles) north-east of Melbourne
is considered as "The Green Wedge Shire" because of the agreement with the Victorian Government
Victorian Government
which prevents high-density infrastructure to be built.


The São Paulo
São Paulo
City Green Belt Biosphere Reserve – GBBR, an integral part of the Atlantic Forest Biosphere Reserve, was created in 1994 stemming from a people's movement that collected 150 thousand signatures. It extends throughout 73 municipalities including São Paulo metro and the Santos area. With approximately 17,000 km², it is inhabited by about 23 million people, corresponding to more than 10% of the country's total population in an area equivalent to 2 thousandth of the Brazilian territory. There are over 6,000 km² of forests and other Atlantic Forest ecosystems at the Reserve, one of the planet's most threatened biomes. In addition to a spectacular biological diversity, the GBBR's ecosystems render valuable ecosystem services.


Greenbelt – Surrounds the Capital city of Ottawa Greenbelt (Golden Horseshoe), is a 7300 km² band of land that encompasses the rural and agricultural land surrounding the Greater Toronto Area and Niagara Peninsula, and parts of the Bruce Peninsula. It is larger than Canada's smallest province of Prince Edward Island. Most of the land consists of the Oak Ridges Moraine, an environmentally sensitive land that is a major aquifer for the region, and the Niagara Escarpment, a UNESCO
Biosphere Reserve. In an effort to restrain urban sprawl that has encroched on these lands, the Ontario
government created the Greenbelt Act in February 2005 to protect this greenspace from all future development, with the exception of limited agricultural use. British Columbia
British Columbia
– the Agricultural Land Reserve protects agricultural land throughout this mountainous province from urban development, including around Vancouver. This protection is strict and urban development of agricultural land is only allowed if no reasonable alternative exists. However, it does not protect non-agricultural land, particularly hillsides, leading to substantial, and highly visible, leapfrog-type hillside sprawl. Quebec
– The Commission de protection du territoire agricole du Québec asserts its mission, namely to keep a territory (the agricultural zones) that is favorable for the practice and the development of agricultural activities. In so doing, the commission safeguards the agricultural territory and helps make its protection a local priority. The agricultural zones cover an area of 63 000 square kilometres in 952 local municipalities.

Dominican Republic[edit]

The Greater Santo Domingo has a Greenbelt (Santo Domingo Greenbelt) project surrounding the whole Distrito Nacional. It is composed of the National botanical Garden, Mirador Del Norte, Mirador del Este, and other parks surrounding the area from its outer municipios. It has largely been affected by uncontrolled urbanization, but other parts remain unaffected.[11][12]


afforestation beyond an expressway in Tehran, Iran

Green Belt in Tehran
has always been a consequential matter due to the rapid increase of the city size, population, cars, factories, pollution and other expansions which hardened breathing. By a big project, the green belt of Tehran
increased from 29 square kilometres in 1979 to 530 square kilometres in 2017 and the number of parks also increased from 75 in 1979 to 2,211 in 2017 in total urban and suburb areas. Such actions and afforestation increased the humidity level and precipitation chance in the city which cools the summer's temperatures down by up to 4°C. Tehran
municipality announced to increase the green belt by 10 square kilometres each year.[13][14]
