Step 1: Understanding the Concept:
Watershed management involves the scientific conservation of water and soil.
It focuses on harvesting rainwater through structures like check dams, percolation tanks, and afforestation.
Several state and central initiatives have been successful in India by involving local communities.
Step 2: Detailed Explanation:
Let's match each program with its correct implementation detail:
1. Hariyali (a): This is a watershed development project sponsored by the Central Government (3).
It is executed by Gram Panchayats with the aim of conserving water for drinking, irrigation, and afforestation in rural areas.
2. Neeru-Meeru (b): This translates to "Water and You" in Telugu. It is a flagship water conservation program of Andhra Pradesh (1).
It involves local people in constructing water-harvesting structures to recharge the groundwater table.
3. Arvari Pani Sansad (c): This is a community-based "Water Parliament" formed in the Alwar district of Rajasthan (2).
It was organized to manage and restore the Arvari river, transforming a once drought-stricken area into a water-sufficient one through traditional harvesting methods.
Mapping these matches: a $\rightarrow$ 3, b $\rightarrow$ 1, c $\rightarrow$ 2.
Step 3: Final Answer:
The correct combination is a-3, b-1, and c-2.
This matches option (C).
