The document discusses several strategies for managing development pressures at the rural-urban fringe: 1) New towns can be built to relieve overcrowding in cities and encourage industries, with the goal of making them self-contained communities. 2) Green belts of farmland and green space can be established around cities to contain urban sprawl, although development sometimes still occurs beyond green belts. 3) Special habitats can be protected through designation as Sites of Special Scientific Interest to prevent development. 4) Redeveloping city centers and brownfield sites can encourage growth in urban areas and reduce pressures at the fringe.
