Here are seven important agricultural uses for water: 1. Produce at the Supermarket. Put simply, one of the most common agricultural uses of water is to produce crops, fruits, and vegetable. Almost every type of food plant needs water, and without agriculture water, there would be a marked reduction in food production. All together water is the most important input in agriculture; the agricultural productivity and its sustainability depend on the timely and sufficient availability of water. In Pakistan, the space between water demand and supply has increased manifolds, due to more agriculture activities and reduced river flow. Agriculture production is highly dependent on water and increasingly subject to water risks. It is also the largest using sector and a major polluter of water. Improving agriculture's water management is therefore essential to a sustainable and productive agro-food sector. Agriculture is expected to face increasing water risks in the future water available. Equally important is the use of engineering and agro- nomic practices which, conjointly, will control and conserve water and counteract the erosive action of both water and wind on the soil. In conjunction with these two basic principles, there must be put back into the soil what is taken out—organic matter, nitrogen, the mineral Water resources for agriculture and food production are classified as either surface or underground water. In humid climates surface water is the main source for irrigation systems. Under sub-humid and arid conditions, underground water is the major water resource for agriculture and food production. The inland navigable waterways are essential to moving farm products to grain export elevators along the Gulf. U.S. corn and soybean farmers are the most efficient in the world. Our country's waterways and multimodal transportation network provides a competitive edge in global markets. Status Quo 160.8 Total Cumulative Volume Impact to 2045 availability in India; its usage in agriculture; water smart technologies developed in agriculture and how India is attempting to move towards sustainability. 2. Rice, which is an important export crop, consumes as much as 3,500 liters of water for a kilogram of grain produced. 3.2. Water availability in different regions of India A variety of methods to explore agricultural water conservation was employed to maximize the Workgroup's input and obtain differing points of view. The following steps were included in the process: 1. Collect and analyze data. 2. Select and develop case studies. 3. Explore focused conservation topics. 4. Identify opportu nities and challenges. Improving water use efficiency or enhancing agricultural water productivity is a critical response to growing water scarcity, including the need to leave enough water in rivers and lakes to sustain ecosystems and to meet the growing demands of cities and industries. Originally, crop physiologists defined water use efficiency as the amount of The present study, Agricultural Water Use and River Basin Conservation, is an important contribution to our policy and field actions. It provides an assessment of the crops that use most water in nine large river basins that are globally important for biodiversity conservation. The study also recommends a series of measures for the four Agriculture is the major user of water in most countries. It also faces the enormous chall
