Climate change exacerbates drought risk by causing rising temperatures, altering precipitation patterns, and increasing evaporation, leading to drier conditions and more frequent/severe droughts in south Bihar regions.
It is, therefore necessity to tap and utilise Ganga water in the monsoon season to meet the shortfall of irrigation need in the Kiul-Harohar basin.
It seems that Ganga water may have to be planned to be transferred to the Kiul-Harohar basin by diversion through lifting water through pumps, making it possible to raise the average irrigation intensity of the region to at least 167%.
