Step 1: Understanding the Concept:
To arrange these Indian government watershed and rural development programs chronologically, we must identify the launch year of each initiative.
Detailed Explanation:
Let us establish the historical timeline of each program:
- (A) Drought Prone Area Programme (DPAP): Launched in ______1973-74______ during the Fourth Five-Year Plan.
Its goal was to minimize the adverse effects of drought on crop production, livestock, and land/water resources in drought-prone areas.
- (B) Desert Development Programme (DDP): Launched in ______1977-78______ based on the recommendations of the National Commission on Agriculture.
It aimed at controlling desertification and restoring ecological balance in hot and cold desert regions.
- (C) Operational Research Projects (ORP) on integrated watershed management: Initiated by ICAR in ______1983-84______ across different agro-ecological regions.
These projects demonstrated the impact of soil and water conservation technologies on a watershed scale (such as the Sukhomajri model).
- (D) National Watershed Development Programme for Rainfed Areas (NWDPRA): Launched during the Seventh Five-Year Plan in ______1990-91______.
It focused on agricultural productivity and natural resource conservation in rainfed regions.
Arranging these chronologically based on their launch years:
DPAP (1973-74) $\rightarrow$ DDP (1977-78) $\rightarrow$ ORP (1983-84) $\rightarrow$ NWDPRA (1990-91).
This matches the sequence (A), (B), (C), (D).
Step 2: Final Answer:
The correct chronological order corresponds to option (A).
