Why are the methods of conserving water resources?

Explanation

### Step-by-Step Solution:

1. **Reducing Agricultural Water Wastage**:
- One of the primary methods to conserve water resources is to reduce the wastage of water in agriculture. This can be achieved by improving the efficiency of irrigation systems. Techniques such as drip irrigation or sprinkler systems can minimize water loss and ensure that water reaches the plants directly.

2. **Afforestation and Protection of Watersheds**:
- Planting trees (afforestation) and protecting existing watersheds are crucial for conserving water. Trees help in maintaining the water cycle, improving soil quality, and preventing soil erosion, which in turn helps in retaining water in the ecosystem.
