这项研究是在2011年进行的调查the impacts of Kol-dam construction on people and their overall economy. There was a loss of total land holding per family in the range of 33.07 to 64.46 per cent in 5 affected villages selected for the study. However in case of cultivated land there was a loss in the range of 36.15 to 67.36 per cent in 5 sampled villages. Submergence of land resulted in the loss of different trees (fodder, timber, fuel wood and fruit) from villages’ farmland in the range of 37.45 to 80.60 per cent in 5 affected village. There was a substantial decrease in the livestock population which ranged from 52.50 to 59.60 per cent. Construction of dam resulted in loss of assets to the extent of 33.33 to 45.45 percent in different villages. Overall there was a decrease in on-farm sectors (crop & livestock) ranged from 42.86 to 81.17 per cent whereas an increase in off- farm income (jobs and private business) ranges from 13.33 - 48.33 per cent has been observed from the affected villages. Hence it can be concluded that there was a loss of on-farm income resources like agriculture land and its associated resources i.e. important tree species and livestock. This might have serious impact on local biodiversity as well as on the life style of project affected families.
