For years Vijendra Tadvi, a 39-year-old farmer in the western state of Gujarat, has been struggling to find water to irrigate his three acres (1.2 hectares) of farmland.
He grows chilli, corn and groundnuts. Like millions of farmers across India, he relies on monsoon rains to water his crops. or he pumps out groundwater, which supports 80% of the rural water supply and farm irrigation. But long dry summers followed by erratic rains have led to frequent drought and shrunk the incomes of farmers like Mr Tadvi.
