The correct answer is C. both (a) and (b).
The Command Area Development Programme (CADP) is a centrally sponsored scheme launched in 1974 with the objective of improving the utilisation of irrigation potential and optimizing agricultural productivity and production from the irrigated area. The CADP is implemented through a number of components, including:
- Irrigation infrastructure development: This includes the construction and maintenance of canals, distributaries, and other irrigation structures.
- On-farm development: This includes the provision of water management infrastructure, such as field channels and water pumps, as well as training and extension services to farmers.
- Agricultural development: This includes the promotion of high-value crops, the provision of credit and marketing support, and the development of rural infrastructure.
The CADP has been successful in improving the utilisation of irrigation potential and optimizing agricultural productivity and production from the irrigated area. The programme has also helped to reduce poverty and improve the quality of life in rural areas.
Option A is incorrect because the CADP also aims to optimize agricultural productivity and production from the irrigated area.
Option B is incorrect because the CADP also aims to improve the utilisation of irrigation potential.
Option D is incorrect because the CADP is a centrally sponsored scheme.
