The Concept of a Green Belt
Defining the Boundary
A green belt, or greenbelt, is a land-use planning policy designating areas of largely undeveloped, wild, or agricultural land surrounding urban centers. These policy zones serve as a buffer, preventing the unchecked expansion of urban development and preserving natural landscapes.
Purpose and Function
Similar to greenways or green wedges, green belts aim to maintain distinct urban boundaries, protect natural environments, improve urban air quality, and provide residents with access to the countryside for educational and recreational purposes. They also help preserve the unique character of rural communities adjacent to urban areas.
Beyond Urban Limits
While the term "green belt" is specific, the broader concept of "green space" or "greenspace" is used in the United States to encompass any undeveloped area, from large tracts to small urban parks. Green belts, however, specifically refer to these encircling zones designed to manage urban growth.
Stated Objectives of Green Belt Policy
Environmental Preservation
A primary objective is to protect natural or semi-natural environments. This includes maintaining biodiversity by providing contiguous habitat networks for plants, animals, and wildlife, crucial for ecological balance.
Urban Environmental Quality
Green belts are intended to improve air quality within urban areas. The presence of vegetation helps filter pollutants and regulate temperature, potentially mitigating the urban heat island effect.
Recreational Access
They ensure that urban dwellers have access to the countryside, offering opportunities for walking, camping, biking, and other recreational activities. This connection to nature is vital for public health and well-being.
Preventing Urban Absorption
Green belts protect the unique character of rural communities that might otherwise be absorbed by expanding suburbs. This helps maintain distinct identities and prevents the homogenization of landscapes.
Historical Evolution of Green Belts
Ancient Precedents
The concept of demarcating undeveloped land around settlements has historical roots. In the 7th century, Muhammad established a green belt around Medina by prohibiting tree removal. Later, in 1580, Elizabeth I of England banned new buildings within a three-mile radius of the City of London to curb plague spread, though enforcement was inconsistent.
Modern Origins
The modern concept emerged from European practices, notably Vienna's Ringstrasse. In the UK, the term gained traction in the late 19th century, with proposals for London's green belt gaining support in the early 20th century. The policy was formally established in England in 1955 to prevent urban sprawl and merging of towns.
Critiques and Challenges
Housing Affordability and Prices
A significant criticism is that green belts, particularly around prosperous cities, can artificially inflate housing prices. By restricting supply within the designated zone, they increase demand and cost for properties both inside and adjacent to the belt, potentially exacerbating housing shortages.
Urban Sprawl and Commuting
Paradoxically, green belts can sometimes encourage urban sprawl beyond their boundaries. Development may "jump" over the green belt, leading to the creation of satellite towns that function as suburbs, increasing commute distances, traffic congestion, and reliance on private transportation.
Effectiveness and Alternatives
Critics question the actual effectiveness of green belts in preserving the countryside, noting that they can sometimes act as land reserves for future infrastructure like highways. Concerns are also raised about the limited use of green belts for recreation by the general population and the potential for other planning restrictions to be more impactful.
Global Green Belt Initiatives
Australia
Adelaide's Central Business District is encircled by the extensive Adelaide Parklands. Melbourne's Shire of Nillumbik is designated as "The Green Wedge Shire," preventing high-density development. Sydney is bordered by national parks and the Western Sydney Parklands.
Canada
The Ottawa Greenbelt, established in 1956, surrounds the capital. The Golden Horseshoe Greenbelt in Ontario protects a vast area around the Greater Toronto Area, including environmentally sensitive lands like the Oak Ridges Moraine and Niagara Escarpment.
United Kingdom
Green belts were formalized in England in 1955. They cover significant areas around major conurbations, aiming to prevent urban merging. Criticisms include their role in restricting housing supply and potentially contributing to sprawl beyond their boundaries.
United States
Several US states mandate Urban Growth Boundaries (UGBs). Notable cities include Portland (Oregon), Lexington (Kentucky - first US greenbelt in 1958), and Virginia Beach. The New Deal created three specific greenbelt communities: Greenbelt, Maryland; Greenhills, Ohio; and Greendale, Wisconsin.
Iran
Tehran has a significant green belt project, expanding its area considerably over decades. Afforestation efforts have reportedly improved humidity and reduced summer temperatures, with a goal to add 10 sq km annually.
South Korea
Green belts were introduced in 1971 to control urban sprawl around Seoul and other metropolitan areas. Objectives include national security, preventing land speculation, protecting agriculture, and environmental conservation, though initial boundary drawing lacked public input.
