The farmers in Tamil Nadu are a community who pray for rains in their neighbouring state as well. It’s an annual plea to god—and not exactly inspired by altruism. For, only a bountiful southwest monsoon can fill up Karnataka’s reservoirs along the Cauvery that feeds the sprawling rice fields eastward, across the border downstream. Today, Tamil Nadu faces its worst agriculture scenario in recent times: the rains were scantiest in 120 years when Karnataka, too, is facing a dry year. With very little Cauvery water from its riparian neighbour and even less from the skies, 2016-17 is proving to be Tamil Nadu’s most barren year in over a century.
