- Green belt
A green belt or greenbelt is a policy or land use designation used in
land use planningto 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 those countries which have them, development in green belt areas is heavily restricted. The stated objectives of green belt policy are to:
* Protect natural or semi
air qualitywithin urban areas;
* Ensure that urban dwellers have access to countryside, with consequent educational and recreational opportunities; and
* Protect the unique character of
ruralcommunities which 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.
Habitatfor 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 fringeuses 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.
The Old Testament outlines a proposal for a green belt around the Levite towns in the Land of Israel [Numbers 35:1-5] Moses Maimonides expounded that the greenbelt plan from the Old Testament referred to all towns in ancient Israel. [Mishna Torah, Zeraim, Shmittah & Yovel 13:4-5] In the 7th century,
Muhammadestablished a primitive form of a green belt around Medina. He did this by prohibiting any further removal of trees in a 12-mile long strip around the city. [Iqbal, Munawwar (2005). "Islamic Perspectives on Sustainable Development". p. 27. Published jointly by Palgrave Macmillan, University of Bahrain, and Islamic Research and Training Institute.] In 1580 Elizabeth I of Englandbanned new building in a 3 mile wide belt around the City of Londonin an attempt to stop the spread of plague. It was however possible to buy dispensations which reduced the effectiveness of the proclamation.

Green belt policy was pioneered in the
United Kingdomin the 1930s after pressure from the CPREand various other organizations. 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 (UK). Other notable examples are the Ottawa Greenbelt and Golden Horseshoe Greenbelt [http://www.ourgreenbelt.ca] , green belts in Ontario, Canada. Ottawa's 20,350 hectaregreenbelt is managed by the National Capital Commission(NCC). [National Capital Commission.

Accessed 28 June 2008.] The more general term in the U.S. is green space or greenspace, which may be a very small area such as a park.
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 [http://www.map21ltd.com/COSTC11-book/index.htm COST Action C11] (European Cooperation in the field of Scientific and Technical Research) is undertaking [http://www.map21ltd.com/COSTC11-book/pdfs/b-Cases.pdf "Case studies in Greenstructure Planning"] involving 15 European countries.
An act of the Swedish parliament from 1994 has declared a series of parks in
Stockholmand the adjacent municipality of Solna to its north a "national city park" called Ekoparken(the "Eco park"; it stretches from the parks surrounding the royal palaces of Ulriksdal and Haga in Solna, through the Brunnsvikenarea, down to the former royal hunting grounds of North and South Djurgården).
A different/contrarian interpretation of the green belt's effects/motivation (for example, suggested by economist
Tim Harford[http://www.randomhouse.com/rhpg/catalog/display.pperl?isbn=9780345494016&view=excerpt] ) is that a green belt is created by residents to preserve the bourgeois status quoof those already living within the zone, and especially the advantage of landlordswho profit from a scarcity of housing (see above, "preserving the character of rural communities"). In this interpretation, the stated motivation and benefits of the green belt are well-intentioned (public health, environment), but these benefits accrue as intentioned or claimed (for example, critics claim that only a small fraction of the population ever sets foot on the green belt for leisure purposes,Fact|date=October 2007 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 maintain the middle class status quo,Fact|date=October 2007 thus exacerbating high housing prices by concentrating demand within the zone and stifling competitive forces in general.
Another area of criticism comes from the fact that, since a greenbelt does not extend indefinitely outside a city, it might spur the growth of areas much further away from the city core than if it had not existed, thereby actually "increasing" urban sprawl. [How Much Open Space is Enough?" St. Paul Pioneer Press (MN) - April 22, 2007 - A1 MAIN] Examples commonly cited are the
Ottawasuburbs of Kanata and Orleans, both of which are outside the city's greenbelt, and are currently undergoing explosive growth (see Greenbelt (Ottawa)). This can lead to other problems, as residents of these areas have further to commute to work (if they seek employment in city) and little access to public transport. It also means people will commute through the green belt, an area not designed to cope with high levels of transportation. Not only is the merit of a green belt apparently subverted, but the green belt may heighten the problem and make the city unsustainableFact|date=July 2008.
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.
In Britain, greenbelt barriers to urban expansion have been strongly criticised as one of several major protectionist political-economic barriers to housebuilding with negative effects on the supply, cost/prices, and quality of new homes. (The other barriers include new housing development taxes and quasi-taxes; political discrimination against particular classes of new housing supplier, household consumer, and housing product; and controls on housing technical-product development – in particular, the blocking of innovative low-cost housebuilding using new materials and production technologies). Critics argue that the greenbelts actually 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
infrastructureand 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.

Adelaide's Central Business District is completely encircled by the Adelaide Parklands, as was initially planned in 1837.
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 Paulometro 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.
* Ottawa 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 Areaand Niagara Peninsula, and parts of the Bruce Peninsula. Most of the land consists of the Oak Ridges Moraine, an environmentally sensitive land that is a major aquiferfor the region, and the Niagara Escarpment, a UNESCOBiosphere 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- the Agricultural Land Reserveprotects 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.

Ann Arbor, Michiganis acquiring conservation easements on agricultural land around the city without the establishment of an urban growth boundary. While the city's initial plan did not include the participation of surrounding townships, at least four townships have participated directly or have initiated their own efforts to protect agricultural land surrounding the city.
