A greenbelt is a ring of undeveloped, natural, or agricultural land surrounding a city or urban area, protected by zoning laws to limit urban sprawl. It acts as a buffer between the built environment and rural landscapes, preserving ecosystems, air quality, and open space. Greenbelts support biodiversity, enable recreational use, and often house critical infrastructure like water catchments or farmland. Their strategic placement in city planning helps direct growth inward and encourages more efficient land use. The concept is rooted in sustainable development and is commonly implemented through land-use policies and conservation easements.
