How and to what extent would micro-irrigation help in solving India’s water crisis? (GS 3 , UPSC 2021)
Water is a scarce natural resource but the major requirement in the agricultural sector. The efficient use of available water for irrigation is a major challenge. A nation with annual water availability of below 1,700 kilolitres per head is considered water deficient. India’s per capita water availability is estimated at 1,428 kilolitres per year.
Micro-irrigation is a modern method of irrigation by which water is irrigated through drippers, sprinklers, foggers and by other emitters on the surface or subsurface of the land. Sprinkler irrigation and drip irrigation are the commonly used micro-irrigation methods.
