Keoladeo National Park (KNP) is an important wintering ground for thousands of birds that undertake a perilous journey over the Himalaya to make a seasonal home in a wetland ecosystem. However, this wetland is now getting polluted by various types of contaminants such as pesticides because of the agricultural practices in the catchment area from where the park receives water. Keeping this in mind, the present study has been undertaken to assess the organochlorine pesticide (OCP) residues in the sediments inside and around KNP. Samples were collected from the different blocks of the park.

This assessment of cumulative impacts of hydroelectric projects in Alaknanda and Bhagirathi river basins in Uttarakhand. It takes into account impact of 70 Hydro Electric Projects of which 17 are existing, 14 are under-construction and 39 are proposed.
