The maximum irrigation potential of India is created through:
Correct Answer:
(C) Minor Projects
Irrigation Projects in India are classified into three categories:
Minor Irrigation Projects: All groundwater and surface water schemes that have a Culturable Command Area (CCA) up to 2,000 hectares individually are classified as Minor Irrigation Schemes. The minor irrigation projects comprise all groundwater development schemes such as dug wells, private shallow tubewells, deep public tubewells, and boring and deepening of dugwells, and small surface water development works such as storage tanks, lift irrigation projects, etc. 62 percent irrigation potential of India is created through minor irrigation projects.
Medium Irrigation Projects: Those having a CCA between 2,000 hectares and 10,000 hectares fall under the category of medium irrigation projects.
Major Irrigation Projects: Irrigation projects having Culturable Command Area (CCA) of more than 10,000 hectares each are classified as major projects. 38 percent of the irrigation potential of India is created through major and medium irrigation projects.
