Q.19. Case Study Based -3: Over the years, there has been a decrease in surface water use and a continous increase in
groundwater utilization for irrigation Figure illustrates the pattern of use of the main sources of irrigation. As can
be seen, the share of tubewells has increased exponentially, indicating the Increased usage of groundwater for
imigation by farmers. The dependence of irrigation on groundwater increased with the onset of the Green
Revolution, which depended on intensive use of inputs such as water and fertilizers to boost farm production
Incentives such as credit for Irrigation equipment and subsidies for electricity supply have further worsened the
situation Low power tariffs has led to exdessive water usage, leading to a sharp fall in water tables.
