- Protection against water pollution
If the total amount of water present on Earth remains contamination free, it is adequate to meet the drinking water needs of the current populace of the world, sadly a huge segment of fresh water doesn’t stay fit for utilization of the living scene because of expanding financial exercises, urbanization and so on.
Main source of fresh water – rivers and lakes and underground water is found under land at different depths are getting extensively polluted.
Enormous urban communities situated on banks of waterways are straightforwardly arranging off various squander without treatment in streams. Additionally, the travel industry has spread contamination at warp speed on well-known lakes and ocean coasts. Man is extraordinarily reliant on groundwater for his water-related necessities, yet some uncommon mechanical units have likewise dirtied this measure of water put away in the security front of the ground.
- Equal distribution of surface water
Water found on the surface of the earth isn’t equally conveyed. The current type of distribution additionally turns into an explanation behind the water emergency. In the African mainland, however, there is most extreme hydroelectric creation due to abundance accessibility of water in Mediterranean locales, the Sahara desert arranged in the north of Africa and the best desert of the world experiences a water emergency for the entire year.
Hence, by arranging supply of water from areas having lesser demand to the areas having greater demand, water crisis can be minimized. By construction of surface water reservoirs and storage of excess water in them, supply can be made to scarcity affected areas. This work can be accomplished by development of water reservoirs and canal network.
Excess rainfall water which flows away from rivers without being used, can be stored by construction of water reservoirs, from where it can be supplied for agriculture, industries, urban areas etc. Facilities of fisheries and transport also exist in stored water. These reservoirs are also constructed for protection from floods, and apart from flood protection, such water can also be used for different purposes. Redistribution of water is also possible through canal system. Canal system transfers water from excess rain water areas to scarce rain water areas and conserves water for different uses.
- Objective Use of Groundwater
Groundwater meets 25 percent of the absolute stock of water on the planet; the leftover 75 percent supply is met by surface water wellsprings of waterways, lakes, and so on. Interest for groundwater continues expanding in relation to its accessible amount because of which amount of groundwater continues diminishing. After the misuse of groundwater, its re-invasion sets aside a long effort to finish.
Thus, groundwater abuse should be just with respect to its energizing limit. In India, the most extreme groundwater is used for farming. Rather than developing yields requiring water as per farming climatic conditions, harvests of business significance requiring more water are developed, because of which over-exploitation of groundwater is finished.
- Renovating Conventional Water Source
Due to increasing area of agriculture, drainage area of water has been destroyed resulting in reduction of water flow therein. This has caused crisis for the existence of traditional water sources. Water crisis can be prevented by renovating traditional water conservation sources. Unless complete conservation of rain water is done in any region, the dream of water conservation cannot be fulfilled. Hence, supervision has to be done regarding renovation of dying traditional water conservation places.
- Implementation of modern Irrigation methodologies
At the world level, 69 percent of water is utilized for the farming area. The essential prerequisite of water in horticulture is met by surface water sources and groundwater. Surface water utilized for agribusiness is acquired through channels and tanks and underground water from wells and cylinder wells. Tragically, much water is squandered through conventional techniques for the water system. The waterway water system doesn’t convey water in a decent manner and it makes issues of water logging.
Because of expanding deforestation during the only remaining century, the majority of the water streamed away to the saline oceans without penetrating into the ground. Water emergency likewise created during the most recent decade in several places, which gets the most noteworthy precipitation on the planet. Because of it, rain water streams away quickly to the waterways.
The conventional way of planting tree ranch on the banks of waterways should be adopted. Forest cover should be created on uncultivable badlands and uneven inclines for a huge scope. Since trees bear dry season conditions for a long span when contrasted with crops, consequently trees are useful in lessening the interest for water alongside energizing water sources.
- Flood management
Increase in afforestation can likewise give security from floods. It will be useful in the retention of water in the soil. Seepage regions of Ganges, Yamuna, Mahanadi, Damodar, Kosi, and different waterways have been taken up in flood the board, and security as far as possible has been given to the 1.44 crore hectare land.
