Farmers rely on water to sustain their agriculture crops, e.g., wheat, paddy, etc. It is an absolute requirement for all living organisms. Typical sources of agricultural water include: Surface water. According to the United States Geological Survey (USGS), water used for irrigation accounts for nearly 65 percent of the world’s freshwater withdrawals excluding thermoelectric power (1). Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. 1. Up to 70 % of the water we take from rivers and groundwater goes into irrigation, about 10% is used in domestic applications and 20% in industry. Until recently, the type of water source has been indicative of the potential risks of contamination. Its availability, or scarcity, can mean a successful harvest, or diminution in yield, or total failure. 4th ed. Water is a substance with the unique property of being able to exist in three states: liquid, solid, and gas. Domestic water use, industry, and irrigated agriculture can each have a blue water footprint. Benefits include: In addition, robotic technologies enable more reliable monitoring and management of natural resources, such as air and water quality. On the other hand, the injury caused by acid rain  indicates that purity and quality relate to the importance of water. Irrigation has increased agricultural productivity but there are issues. For example, if a chronic test in fish showed no effects at 10μg/L, an assessment factor of 10 is still added, meaning that the acceptable concentration in water would be only 1μg/L. Use of water in food and agriculture Food and agriculture are the largest consumers of water, requiring one hundred times more than we use for personal needs.
