PLANNING FOR WATER AND LAND: SUSTAIN ABILITY OF EXPANDING CITIES

摘要

Peri-urban areas are zones of transition from rural to urban land uses located between the outer limits of urban and regional centres and the rural environment. The boundaries of peri-urban areas are porous and transitory as urban development extends into rural and industrial land. Irrespective of how the boundaries move, however, there will always be peri-urban zones. There are growing concerns about water and food security to meet increases in population in urban areas. For cities to be liveable and sustainable into the future there is a need to maintain the natural resource base, food production and the ecosystem services in the peri-urban areas surrounding cities.
