Introduced in 2015 by the Government of India with an investment of ₹ 50,000 crores (US$ 7.7 billion), PMKSY is a national mission aiming to develop irrigation sources to offer a permanent solution to drought. It carries with it the motto of "Har Khet Ko Paani".
The aim of this mission's implementation is to expand cultivated areas along with assured irrigation, improve water use efficiency, and lower water wastage. PM Krishi Sinchai Yojana focuses on generating sources for assured irrigation and creating protective irrigation by harnessing rainwater at the micro-level through "Jal Sinchan" and "Jal Sanchay". Besides these, micro-irrigation is incentivised through subsidies for ensuring "Per drop-More crop".
PMKSY Yojana has been formulated by the amalgamation of some ongoing schemes. This includes the following:
- Accelerated Irrigation Benefit Programme (AIBP) of the Ministry of Water Resources
- River Development & Ganga Rejuvenation (MoWR, RD&GR)
- Integrated Watershed Management Programme (IWMP) of Department of Land Resources (DoLR)
- On Farm Water Management (OFWM) of Department of Agriculture and Cooperation (DAC)
