Four methods for providing water in times of low rainfall are:
1. Rain water harvesting through which rain water is collected for domestic use and recharging groundwater.
2. Construction of dams for providing water to dry regions.
3. Linking of rivers so that water is transferred from surplus river to deficient areas.
4. Construction of bunds and dig pits or ponds for collection of surplus water during rainy season.
Explanation:
- Water conservation is significant as two-third of the world is facing the problem of dryness.
- The methods described above is significant along with change in agricultural practices such as promoting drought-resistant crops in dry regions.
- Water demanding crops must be irrigated well and where possible sprinkler and drip irrigation facilities must be used.
- Minimal wastage of water and reuse must be promoted.
- Unpolluting the rivers and minimising the discharge effluent wastes from industries is necessary.
