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) is designed for the holistic development and management of land and water resources within a specific watershed area. Its primary benefits and objectives include: Prevention of soil runoff: Watershed development emphasizes soil conservation measures like contour bunding, terracing, afforestation, and vegetative barriers, all of which significantly reduce soil erosion and runoff. This is a core benefit. Linking the country's perennial rivers with seasonal rivers: This refers to the National River Inter-linking Project, which is a large-scale, separate infrastructure initiative aimed at transferring water from water-surplus basins to water-deficit basins. It is not a direct component or benefit of a typical watershed development program, which focuses on localized, in-situ water and soil conservation. Rainwater harvesting and recharge of groundwater table: A fundamental aim of IWDP is to capture rainwater through various structures (e.g., check dams, farm ponds, percolation tanks) and promote infiltration, thereby replenishing groundwater aquifers. This is a major benefit. Regeneration of natural vegetation: The program encourages afforestation, agroforestry, and the adoption of sustainable land-use practices within the watershed, leading to improved vegetation cover. This regeneration helps in soil moisture retention, reduces erosion, and enhances biodiversity. This is a significant benefit. Thus, statements 1, 3, and 4 correctly describe the benefits of the Integrated Watershed Development Programme.
