Even the World Bank admits that mining in Keonjhar haven't been a boon for the local inhabitants. Based on detailed study of a large sample of villages in Keonjhar, using quantitative as well as spatial analysis, the study finds that "In terms of indicators of overall welfare, villages closer to mines have poorer health, education and production assets. These impacts are likely partly due to the impact of mines on forest quality. Proximity to mines is associated with reduced forest quality, as measured by the diversity of forest products available to village residents."
It also goes on to say "The villages closest to mines appear to bear a greater environmental cost".
