Overview

The course “Biodiversity and Ecological resources” would serve a 04 credit Core Course in B.Sc. Environmental Science, under the Choice Based Credit System (CBCS) of UGC. The course would also be useful as one of the compulsory subject for all students of the undergraduate streams, e.g. arts, science, commerce and other biomedical sciences. The environmental studies course gives an overview towards understanding of basic environment and ecological services. The conservation and management of natural resources besides use and over exploitation is also detailed in the course. The decline in Earth's biological diversity has far more deep implications than other environmental dilemmas, sometimes more commonly acknowledged that will be documented her. The ex- situ and in-situ approaches for protection of earth’s biodiversity are the main conservative tools for protection of earth’s biodiversity and will be established in the course. The enormous variety of natural resources on this planet provides everything for survival of all forms of life including man. Forests and wildlife are essential for ecological balance of an area. The energy is critical directly or indirectly in the entire process of evolution growth and survival of all forms of life. Energy security is therefore important for economic growth and alleviation of poverty and unemployment. The programme will give us detailed information about the concept and strategies of sustainable development for the management of all biological resources including the ecological footprint and carbon sequestration for sustainable development.
