11.3.4.2.3. Watershed management practices

In the fifth year plan, watershed management approach was included with a number of programs for it and a national policy was developed. In watershed management, the aspects of development are considered with regard to availability of the resources.

Watershed management is a systematic approach to managing water resources in a specific area, called a watershed, to enhance development while using resources sustainably. The fifth year plan in India recognized the need for managing watersheds and included programs aimed at this goal. The idea is to utilize available natural resources wisely to promote development and prevent degradation.

Think of a watershed like a family budget. Just as you need to balance your income and expenses to maintain a healthy financial state, watershed management balances resource availability and development needs to ensure sustainability.

Various measures taken up for management include the following: 1. Water harvesting: Proper storage of water is done with provision for use in dry seasons in low rainfall areas. It also helps in moderation of floods.

Water harvesting involves capturing and storing rainwater for use during dry periods. This practice is especially useful in regions with low rainfall, as it ensures a reliable water supply, mitigates the impact of floods, and enhances the overall water availability in the watershed.

Imagine storing rainwater in barrels or tanks during the rainy season, which you can then use to water your garden or drink during the dry months. This not only ensures you have access to water when needed but also prevents water from overflowing and causing flooding.

2. Afforestation and agro-forestry: In watershed development, afforestation and crop plantation play a very important role. They help to prevent soil erosion and retention of moisture.

Afforestation refers to planting trees in an area where there were none previously, while agroforestry integrates trees and shrubs into crop and livestock farming systems. These practices enhance soil stability, prevent erosion, and help retain moisture in the ground, which is crucial for sustainable agriculture.

Think of planting trees around a garden as giving it an umbrella. Just as an umbrella protects you from rain and keeps your surroundings drier, trees shield the soil and crops from the direct impact of heavy rain and wind, preventing erosion and keeping the soil healthy.

3. Mechanical measures for reducing soil erosion and runoff losses: Several mechanical measures like terracing, bunding, bench terracing, no-till farming, contour cropping, strip cropping etc. are used to minimize runoff and soil erosion particularly on the slopes of watersheds.

Mechanical soil erosion control strategies help manage both soil erosion and surface runoff. Techniques like terracing reduce the speed of water flow on slopes, while bunding creates barriers to hold soil and water in place. These methods are vital in hilly areas to preserve arable land.

Imagine you are hiking on a steep trail. If the trail is clear, you can slide down easily, causing more erosion. However, if there are steps (terraces) along the way, they slow you down and help keep the trail intact. Similarly, these mechanical techniques slow down water flow, helping to reduce erosion.

5. Public participation: People’s involvement including the farmers and tribals is the key to the success of any watershed management program, particularly the soil and water conservation.

Successful watershed management relies on the active participation of local communities, including farmers and tribal populations. Their involvement ensures that management strategies are practical and meet the needs of those who directly depend on the watershed for their livelihood.

Consider a community garden where everyone has a role—some plant, some water, and some harvest. The garden thrives because everyone contributes. Similarly, in watershed management, when local communities participate, the solutions are more effective and sustainable.
