The On-Farm Development (OFD) activities undertaken under Command Area Development include: (A) Construction of field channels and drains (B) Reclamation of waterlogged areas (C) Renovation and rehabilitation of minor irrigation tanks

Correct option is D

The correct answer is (D) All A, B and C

Explanation:
• The Command Area Development (CAD) program was launched in 1974-75 to bridge the gap between irrigation potential created and utilized.
• On-Farm Development (OFD) refers to activities carried out within the farmer's field to improve water management. This includes Construction of field channels and drains to ensure water reaches every plot and excess water is removed.
• Reclamation of waterlogged areas is a critical component, as poor drainage in irrigation commands often leads to salinity and waterlogging, ruining crop yields.
• Renovation and rehabilitation of minor irrigation tanks helps in the integrated use of surface and groundwater and ensures a reliable water supply for the tail-end of the command area.

Information Booster:
• The program was renamed 'Command Area Development and Water Management' (CADWM) in 2004.
• Warabandi (a rotational system of water distribution) is a key management strategy under CAD.
• Participatory Irrigation Management (PIM) through Water Users' Associations (WUAs) is encouraged under this scheme.

Additional Knowledge:
• Field Channels: These are the small conduits that take water from the government outlets to the individual fields.
• Land Leveling: Another vital OFD activity that ensures uniform distribution of water across the field surface.
