Section II – Issues and Challenges for Urban Environmental Management in Asia Section II – Issues and Challenges for Urban Environmental Management in Asia

Asia has been experiencing very high population growth and urbanization as well as migration as discussed in previous section. Asian cities will witness a large population increase, which will have important implications for a variety of urban environmental issues, such as water supply and sanitation, waste and wastewater generation, urban infrastructures as well as mobility. This section presents an overview of major urban environmental problems faced by Asian cities, focusing on challenges and trends on water supply and sanitation, urban transportation, and waste management. These three sectors represent the main urban environmental problems, especially in the developing cities in Asia. The diversity of economic and social condition in Asian cities leads to different realities in these sectors, which are also discussed here.
