Historical Context
Early Precedents
The concept of a protective buffer around urban centers has historical roots. Queen Elizabeth I, in 1580, enacted a temporary ban on new construction within a three-mile radius of the City of London, primarily to curb the spread of plague. However, this measure was not consistently enforced and could be circumvented through dispensations.[4]
Continental Inspiration
The idea was also influenced by European urban planning, such as the extensive ramparts and parks forming the ''Ringstraรe'' in Vienna, which served as buffer zones. These precedents demonstrated the potential for designated open spaces to shape urban development and provide public amenities.
Modern Proposals
Significant proposals for a modern green belt emerged from the early 20th century. The London Society, in its 1919 ''Development Plan of Greater London'', advocated for a belt to prevent urban sprawl. Alongside the Campaign to Protect Rural England (CPRE), they lobbied for a defined zone beyond which development would be restricted.
Post-War Planning
The interwar housing boom and the rise of private motor transport intensified concerns about London's congestion and pollution. Influenced by French models like the ''couronne pรฉriurbaine'' around Paris and the concept of satellite towns, British policy, particularly under the Attlee ministry, enacted the New Towns Act 1946 and issued circulars encouraging local authorities to designate the Metropolitan Green Belt.
Formalization and Expansion
Herbert Morrison's leadership at the London County Council in 1934 laid policy groundwork. The Greater London Regional Planning Committee formally proposed the belt in 1935. Patrick Abercrombie's 1944 Greater London Plan envisioned a wider belt. The Green Belt Act 1938 and subsequent planning acts, notably the Town and Country Planning Act 1947, enabled local authorities to formally map and implement these designations. Minister Duncan Sandys' Circular 42/55 in 1955 further encouraged nationwide green belt designations, emphasizing their role in preventing urban merging and preserving town character.[7]
Extension and Reduction
Geographical Scope
Following the initial designations, London's green belt was significantly extended after 1955, reaching up to 35 miles from the city center. It now encompasses substantial portions of surrounding counties, including parts of Greater London, Berkshire, Buckinghamshire, Essex, Hertfordshire, Kent, Surrey, Bedfordshire, and a small area in Sussex. The belt's total area is approximately three times the size of London itself.[3]
Integration with Protected Areas
Extensions often incorporated existing protected landscapes, such as the Surrey Hills, Chiltern Hills, and areas like Epping Forest. These designations frequently predate or overlap with other protective measures, including Areas of Outstanding Natural Beauty (AONBs), reinforcing the conservation objectives.
Policy Adjustments
While the policy aims to preserve open land, provisions exist for limited release under "exceptional circumstances" as outlined in planning policies.[9] Areas designated as Metropolitan Open Land within Greater London also receive similar protections, though they are not formally part of the Green Belt designation.[14]
Debate and Controversy
Development Pressures
The Metropolitan Green Belt is a subject of ongoing debate, particularly concerning development pressures and housing needs. Reports, such as the London Society's "Green Sprawl," question the extent to which the belt is overprotected, suggesting potential land release for housing, especially near existing transport hubs.[15]
Commuting Patterns
Research, including studies commissioned by the Royal Town Planning Institute, has analyzed commuting patterns within the green belt. These studies often challenge claims that extensive development would primarily serve London commuters, indicating that many residents utilize private vehicles for local employment, potentially exacerbating road congestion if development occurs without adequate infrastructure planning.[26]
Economic and Housing Factors
Think tanks like the Adam Smith Institute have argued for building on designated green belt land to address the housing crisis, highlighting the availability of land near train stations.[24] Conversely, organizations like CPRE argue that green belts do not inherently inflate house prices, attributing price increases to broader market factors and investment.
Urban Form and Density
Public opinion surveys have also indicated concerns about the proliferation of high-rise developments in London, with significant support for limits on building heights. This suggests a public desire to balance urban growth with the preservation of existing urban character and open spaces.[27]
Designated Area
Geographical Distribution
The Metropolitan Green Belt is a statutory designation covering significant areas across multiple ceremonial counties surrounding London. As of 2017/18, government statistics indicate the designation covered approximately 513,860 hectares (1,269,800 acres).[3]
Local Authority Coverage
The belt extends across numerous local authority districts. For instance, every borough in Surrey and Hertfordshire, most districts in Bedfordshire, and significant portions of Berkshire, Buckinghamshire, Essex, Kent, and London boroughs are included. The specific distribution and percentage of green belt land within each district vary considerably.
