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:
The green belt has many benefits for people:
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.
The Old Testament outlines a proposal for a green belt around the Levite towns in the Land of Israel Moses Maimonides expounded that the greenbelt plan from the Old Testament referred to all towns in ancient Israel. 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. 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, it was possible to buy dispensations which reduced the effectiveness of the proclamation.
In modern times, green belt policy was pioneered in the United Kingdom in the 1930s after pressure from the CPRE and 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 in Ontario, Canada. Ottawa's 20,350 hectare greenbelt is managed by the National Capital Commission (NCC). 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 COST Action C11 (COST - European Cooperation in Science and Technology) is undertaking "Case studies in Greenstructure Planning" involving 15 European countries.

The difference/contrarian interpretation of the green belt's effects/motivation (for example, suggested by economist  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. 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 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 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.
In Britain, greenbelt barriers to urban expansion have been criticised 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 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 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.
