Redefining Urban ecosystems

The chapter tries to trace the development of concept of urban ecosystem as a problem-solving approach for urban problems, including the unwarranted problems caused by climate change. Urban management has increasingly shifted from infrastructure-based to a more regional-based approach. There has been a shift in the domain of urban ecosystem as well, from the established urbanized area to the aggregation of urban and surrounding rural area. Also, urban-rural linkages are given more attention in resource management in urban areas, thereby reducing the overall risk due to climate change. The chapter provides examples and challenges of urban ecosystem management from across the world.
