What are the benefits of implementing the 'Integrated Watershed Development Programme'? 1. Prevention of soil runoff 2. Linking the country's perennial rivers with seasonal rivers 3. Rainwater harvesting and recharge of groundwater table 4. Regeneration of natural vegetation Select the correct answer using the code given below.

The Integrated Watershed Development Programme (IWDP) focuses on local-level ecological restoration, making statements 1, 3, and 4 correct as they address soil conservation, groundwater recharge, and biomass regeneration. Statement 2 is incorrect because the interlinking of rivers is a separate, large-scale national infrastructure project that falls outside the decentralized, micro-level scope of watershed management. The core concept being tested is the distinction between community-based resource management and macro-level engineering projects for water distribution.
