Tube-Well Construction and Groundwater Depth over Time

Source: Data on tube-well construction were obtained from the Minor Irrigation Censuses conducted every seven years since 1986. Groundwater depth was compiled from the Central Ground Water Board which has monitored wells across the country since 1996.

Note: The percentage share of villages with tube-wells is represented by the bar graph with its axis on the left. Annual maximum groundwater depth is represented by the line graph with its axis on the right. The sample consists of villages with tube-wells in 2013 and groundwater depth within the bandwidth (7 m) of the kink point.
