Green belt (United Kingdom)
In United Kingdom town planning, the green belt is a policy for controlling urban growth. The idea is for a ring of countryside where urbanisation will be resisted for the foreseeable future, maintaining an area where agriculture, forestry and outdoor leisure can be expected to prevail. The fundamental aim of green belt policy is to prevent urban sprawl by keeping land permanently open, and consequently the most important attribute of green belts is their openness.
The Metropolitan Green Belt around London was first proposed by the Greater London Regional Planning Committee in 1935. The Town and Country Planning Act 1947 then allowed local authorities to include green belt proposals in their development plans. In 1955, Minister of Housing Duncan Sandys encouraged local authorities around the country to consider protecting land around their towns and cities by the formal designation of clearly defined green belts.
England and Wales
The Government formerly set out its policies and principles towards green belts in England and Wales in Planning Policy Guidance Note 2: Green Belts , but this planning guidance was superseded by the National Planning Policy Framework (NPPF) in March 2012. Planning Authorities are strongly urged to follow the NPPF's detailed advice when considering whether to permit additional development in the green belt. In the green belt there is a general presumption against inappropriate development, unless very special circumstances can be demonstrated to show that the benefits of the development will outweigh the harm caused to the green belt. The NPPF sets out what would constitute appropriate development in the green belt.
According to the NPPF, there are five stated purposes of including land within the green belt:
- To check the unrestricted sprawl of large built-up areas
- To prevent neighbouring towns from merging into one another
- To assist in safeguarding the countryside from encroachment
- To preserve the setting and special character of historic towns
- To assist in urban regeneration, by encouraging the recycling of derelict and other urban land.
Once an area of land has been defined as green belt, the stated opportunities and benefits include:
- Providing opportunities for access to the open countryside for the urban population
- Providing opportunities for outdoor sport and outdoor recreation near urban areas
- The retention of attractive landscapes and the enhancement of landscapes, near to where people live
- Improvement of damaged and derelict land around towns
- The securing of nature conservation interests
- The retention of land in agricultural, forestry and related uses.
The area designated as green belt land in England as at 31 March 2010 was estimated at 1,639,560 hectares, about 13 per cent of the land area.
|Region||2009 area (hectares)||2010 area (hectares)|
|Yorkshire and the Humber||264,580||264,640|
The total area of green belt land in England since 2003 was as follows:
Changes in green belt area are explained in part by alterations in land designation by local authorities, but also by improvements with measurement associated with digital mapping.

Green belt policy in Scotland is set out in Scottish Planning Policy (SPP) 21, published by the Scottish Government in February 2010. On 29 November, the Government published "Green Belt Policy in Scotland 10/85"
As of 2010 Scotland had 10 green belt areas: Aberdeen, Ayr, Clackmannanshire, East Lothian, Edinburgh, Falkirk and Grangemouth, Greater Glasgow, Midlothian and Stirling. There are also plans for green belts around Dunfermline, Perth and St Andrews.
The Scottish Government is clear that:
The purpose of green belt designation in the development plan as part of the settlement strategy for an area is to:
direct planned growth to the most appropriate locations and support regeneration, protect and enhance the quality, character, landscape setting and identity of towns and cities, andprotect and give access to open space within and around towns and cities
However, the Scottish Government recognises that certain types of development might actually promote and support appropriate rural diversification:
- Development associated with agriculture, including the re-use of historic agricultural buildings,
- Woodland and forestry, including community woodlands,
- Horticulture, including market gardening and directly connected retailing,
- Recreational uses that are compatible with an agricultural or natural setting, and
- essential infrastructure such as electronic communications infrastructure and electricity grid connections
The Government requires that locally established green belt plans: maintain the identity of a city by the clearly establishing physical boundaries and preventing coalescence; provide countryside for recreation of denizens; and maintain the landscape setting of the city in question. In its Planning Policy (129), the Scottish Government states that
“All public bodies, including planning authorities, have a duty to further the conservation of biodiversity under the Nature Conservation (Scotland) Act 2004, and this should be reflected in development plans and development management decisions. Biodiversity is important because it provides natural services and products that we rely on, is an important element of sustainable development and makes an essential contribution to Scotland's economy and cultural heritage.”
The introduction of green belts was the culmination of over 50 years of environmentalist pressure with roots in the garden city movement and widespread academic interest in combating urban sprawl and ribbon development, as well as pressure from campaign groups such as the Campaign to Protect Rural England (CPRE).
Implementation of the notion dated from Herbert Morrison's 1934 leadership of the London County Council. It was first formally proposed by the Greater London Regional Planning Committee in 1935, "to provide a reserve supply of public open spaces and of recreational areas and to establish a green belt or girdle of open space". It was again included in an advisory Greater London Plan prepared by Patrick Abercrombie in 1944. However, it was some 14 years before the elected local authorities responsible for the area around London had all defined the area on scaled maps with some precision.
New provisions for compensation in the 1947 Town and Country Planning Act allowed local authorities around the country to incorporate green belt proposals in their first development plans. The codification of Green Belt policy and its extension to areas other than London came with the historic Circular 42/55 inviting local planning authorities to consider the establishment of Green Belts.
As the outward growth of London was seen to be firmly repressed, residents owning properties further from the built-up area also campaigned for this policy of urban restraint, partly to safeguard their own investments but often invoking an idealised scenic/rustic argument which laid the blame for most social ills upon urban influences. In mid-1971, for example, the government decided to extend the Metropolitan Green Belt northwards to include almost all of Hertfordshire. The Metropolitan Green Belt now covers parts of 68 different Districts or Boroughs.
Several academics, policy groups and town planning organisations in recent years have criticised the idea and implementation of green belts in the UK. Greenbelt policy has been attacked as too rigid in the face of new urban and environmental challenges. Amongst other things, it has been claimed that areas of green belt can be of unremarkable environmental quality, and may not be well managed or provide the recreational opportunities originally envisaged.
The Town and Country Planning Association, an organisation heavily involved in initiating the concept several decades previously, published a policy statement in 2002 which proposed a more flexible policy which would allow the introduction of green wedge and strategic gap policies rather than green belts, and so permit the expansion of some urban areas. Similarly, in October 2007, Sir Martin Doughty, then Chair of Natural England, argued for a review of green belts, saying: "The time has come for a greener green belt. We need a 21st century solution to England's housing needs which puts in place a network of green wedges, gaps and corridors, linking the natural environment and people.".
Lewis Abbott has identified greenbelt barriers to urban expansion 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 others 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). Abbott argues 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.
Commentators such as James Heartfield and Alan Evans have called for outright abolition of green belts, principally on the grounds that by inhibiting the free use of land they restrict home ownership.
However, in England, where 70% of people are property-owners who benefit from scarcity of building land, the concept of "green belt" has become entrenched as a fundamental part of government policy, and the possibility of reviewing boundaries is often viewed with considerable hostility by neighboring communities and their elected representatives.
The general concept of "green belt" has evolved in recent years to encompass "Greenspace" and "Greenstructure", taking into account urban greenspace, an important aspect of sustainable development in the 21st century. However, while in general these concepts are quite distinct in the UK from the green belt as a statutory development plan designation, an exception occurs in London where land may be designated as "Metropolitan Open Land" (MOL). Areas of MOL are subject to the same planning restrictions as the Green Belt while lying within the urban area. In 2005, the European Commission's COST Action C11 (COST European Cooperation in Science and Technology) undertook in-depth city case studies into cities across 15 European countries. Sheffield was one such case study city for the UK. Conclusions were published in "Case studies in Greenstructure Planning".
