Can we copy the experience of the mitigation strategy from Europe or North America? My opinion:The situation differs from the former problems of western countries in many aspects

Background First,the population in urban areas in the developing countries now are much denser than that in the past in the West; Second,there are some special remaining issues in the booming cities within only two or three decades in the developing countries,such as short-sighted urban planning, lack of municipal infrastructure,unreasonable or outdated locations of urban drainage systems and wastewater treatment plants; Third,the environmental debts during the rapid industrialization and urbanization period cause the subsequent environmental problems to be more complicated and interdependent. Environmental infrastructure investment lag behind the present speed of increasing productivity

Catchment a structure in which water is collected (especially a natural or artificial drainage area) watershed: a region or area bounded peripherally by a divide and draining ultimately to a particular watercourse or body of water
