Question

Give three reasons for conservation of water resources.

Answer 1

Hint: Underground water overexploitation also contributes to the depletion of the water table. Population growth has given rise to water shortages. Our water supplies are contaminated, such as subterranean water, ponds, reservoirs, etc.

Complete Answer:
Water management is the method of effectively using water to reduce excessive water consumption. Water is depleting at the rapid rate because of the over population and with its rising demand. So, there are few reasons that arise the need to conserve the water resources. These are:-
1. Uncertainty of Rainfall- in India, rainfall is highly irregular and uncertain. Monsoon is not very predictable. In such a situation, we cannot completely rely on water and there arises a need to conserve the water.
2. Population- Overpopulation is the major cause. It is increasing at a tremendous rate which may lead to the depletion of water resources at a fast pace. Thus, it needs to be conserved.
3. Natural Reservoirs getting polluted- Most of the water in the rivers and other natural resources are getting polluted. It not only needs to be conserved but also needs to be treated to meet the demands of people and farmers.
4. Agricultural applications- Water is an integral part of irrigation. Plants often suck up a lot of ground water, so it is important to replenish groundwater. However, drip irrigation, especially for the home gardener and in light of rising water prices, is increasingly affordable. When replacing irrigation systems that spray in all directions, up to 30,000 gallons of water a year can be avoided by using drip irrigation techniques. Conservation initiatives also focus on optimizing the productivity of the current scheme, since changing irrigation schemes can be an expensive undertaking. This may include the chiseling of compacted soils, the production of furrow dikes to avoid runoff and the use of soil moisture and rainfall sensors to refine irrigation schedules.

Note: In India, many villages now have indigenous rainwater harvesting systems, thereby establishing a grassroots model for environmental sustainability. It is also invested in restoring indigenous water supply systems by harnessing village wetlands, etc. in rural India.
Now farmers are sowing multiple crops because of improved water availability throughout the year by depending only once on rains, leading to increased agricultural incomes. Recharge systems for groundwater have been restored, contributing to water supply even in high summers.
