Degraded Peri-urban biophysical environments in South Asia
Urbanization leads to the deterioration of peri-urban biophysical environments. Urban sprawl encroaches and degrades peri-urban ecosystems,and alters the natural equilibrium. This in turn, depletes the resource base of peri-urban areas.
Urban development policies,plans,and programs treat the peri-urban as an opportunity for urban expansion, and rarely factor issues of environmental sustainability. Thus, peri-urban areas are often selected as suitable places for discharge of urban wastewater and disposal of solid wastes. As a consequence, and because of the haphazard construction of urban infrastructure, the drainage systems of peri-urban areas are severely compromised.
This research brief is based on comparative field research in four South Asian peri urban areas with different biophysical settings. The paper underscores the adverse consequences ofurbanization and climate change and offers policy recommendations.
