What do you mean by optimum utilization of water resources? What is your approach for sustainable utilization of water resources?
In the case of the sustainable use of water aquifer recharge rate would be balanced by aquifer usage giving the ability to maintain a withdraw regime which would not deplete the aquifer resource.
Sustainability of water resources can be promoted by using plansfor soil conservation resulting in greater ability to capture soil water and not have it lost through run off.
Better water utlization can be prompted by capturing roof falls storing it and utlizing the runoff by efficient systems such as drip irrigation.
Calculating the capacity for water usage and using water efficiently is the heart developing a sustainable water use system.
A recognized positive use made of the water in a river, lake or other water body. Beneficial uses include: industrial,domestic, and agricultural water supplies,power plants, aesthetic enjoyment,fish and wildlife resources, contact recreation, and others. Water quality standards are set to support the recognized beneficial uses of a water body.
The term optimum utilization of water is directly indicated that the farmers have to utilize the water optimum level neither minimum level nor maximum level because there are some areas the water scarcity pushed them to supply the adequate quantity of the water to the plants.
It is encouraged or recommended that the farmers should have sufficient quantity which indicates the optimum level of utilization of water for agriculture.
The term Sustainable utilization of water emphasize the continuity of water supply or utilization matters for agriculture.
The approach can be supported the physical watershed management structures like Check-dams, soil and water conservation technologies, community ponds, farm ponds, etc.
Mostly, watershed management structures could support the farmers in many developing countries.
There may be the probability of getting water will be a question mark, so the farmers have to find out the substitute resources other than normal sources.
Watershed management approach is the welcome support to the farmers who are facing the water challenges could be encouraged to adopt any one of the Water conservation technologies in the farm lands.
The optimal use of water resources means the exploitation of water resources without compromising the quality and quantity of these sources, and this means maintaining the sustainability of it.
The balance between the needs and the productive capacity of the resources will maintain the sustainability of these resources
