  • Urban ecosystems are the cities, towns, and urban strips constructed by humans. This is the growth in the urban population and the supporting built infrastructure has affected both urban environments and also on areas which surround urban areas. These include semi or 'peri-urban' environments that fringe cities as well as agricultural and natural landscapes. Scientists are now developing ways to measure and understand the effects of urbanisation on human and environmental health. By considering urban areas as part of a broader ecological system, scientists can investigate how urban landscapes function and how they affect other landscapes with which they interact. In this context, urban environments are affected by their surrounding environment but also affect that environment. Knowing this may provide clues as to which alternative development options will lead to the best overall environmental outcome. CSE's urban ecosystem research is focused on: Understanding how cities work as ecological system Developing sustainable approaches to development of city fringe areas that reduce negative impact on surrounding environments
