Hastinapur Wildlife Sanctuary is a protected area in the Gangetic plains of Uttar Pradesh, India.

This will give lot of employment opportunities to the local population at the same time develop the area for wildlife tourism.

Hastinapur Wildlife Sanctuary occupies an extremely large area spreading on both sides of river Ganga. Wildlife Institute of India (WII) officials say that the sanctuary should be reduced to half of its present area (1094 km). They are saying so because the sanctuary comprises many agricultural fields that need to be excluded are the earliest, however many Wildlife activists feel that this is not good for the sanctuary and say that the agricultural part should be added in the buffer zone of the sanctuary and not be cut out of the sanctuary because if that is done, farmers will sell their lands to builders and then a town will be made outside the forest. Vijay Pal Baghel, who is popularly known as the green man of India said" For the past decade, the government has been trying to erase the sanctuary and when they couldn't do it, they will drastically reduce its size."
