Biodiversity has received much attention in environmental research and public policy in recent years. There is a world-wide interest in its relevance for the carrying capacity of rich but fragile ecosystems. There is also a need to address the ecological and economic issues for developing a wide array of policy options. There is further need to study various economic evaluation approaches for furthering biodiversity conservation along with sustainable development. Towards this end, CERA plans to use ecological and value indicators in integrated economic-ecological modeling and analysis. Further, to assess the status of threatened species and habitats, including sensitive ecosystems, CERA plans to undertake field evaluation studies using technology options such as GIS for interpreting field data.
