Grey belt
In urban planning, the term "grey belt" refers to areas within a city that are characterised by a high degree of impervious surfaces such as concrete, asphalt, and buildings, which are often associated with industrial, commercial, or densely built residential zones. These areas typically have little to no green space or vegetation, leading to various environmental and social challenges. The term "grey belt" is often used in contrast to "green belt," which refers to areas of protected open space or countryside around urban areas designed to limit urban sprawl and provide recreational areas, agricultural land, and wildlife habitats.
Key features include:
- The predominance of surfaces that do not absorb water, contributing to increased runoff and potential flooding.
- The concentration of buildings and paved surfaces can lead to higher temperatures in grey belt areas compared to surrounding rural areas.
- Limited parks, gardens, and natural areas, which can negatively impact residents' quality of life, mental health, and physical well-being.
- Potential for higher levels of pollution (air, water, noise) due to industrial activities and dense traffic.
- Possible socio-economic issues, such as higher population density, limited recreational facilities, and reduced aesthetic appeal.
Urban planners often seek to address the challenges of grey belts through strategies including:
- Introducing parks, green roofs, street trees, and community gardens to increase green space and improve environmental quality.
- Encouraging the use of permeable materials, green building techniques, and energy-efficient infrastructure.
- Promoting developments that combine residential, commercial, and recreational spaces to create more balanced and vibrant communities.
- Enhancing public transportation and pedestrian-friendly infrastructure to reduce reliance on cars and decrease pollution.
NB: "Proposed reforms to the National Planning Policy Framework and other changes to the planning system" Published by the Ministry of Housing Communities and Local Government on 30 July 2024, states:
For the purposes of Plan-making and decision-making, grey belt is defined as land in the Green Belt comprising Previously Developed Land and any other parcels and/or areas of Green Belt land that make a limited contribution to the five Green Belt purposes (as defined in para 140 of this Framework) but excluding those areas or assets of particular importance listed in footnote 7 of this Framework (other than land designated as Green Belt). |
