Answer: Build wind-powered pumps to use groundwater.
Step-by-step explanation:
The process of irrigation of a large farm land requires use of technology. The ground water is the water reservoir which is accumulated in the undersurface regions of the below the earth crust. The water in the underground level get seeps from the pores of the soils and rocks coming from the source of river, lakes, melting glaciers, irrigation, and rain. The use of the wind pump is the relevant option to circulate the groundwater from the natural reservoir to the entire irrigation land when the artificial reservoir depletes water.
