How does water affect agriculture?
Water is one of the most important inputs essential for the production of crops. Plants need it continuously during their life and in huge quantities. It profoundly influences photosynthesis, respiration, absorption, translocation and utilization of mineral nutrients, and cell division besides some other processes. Both its shortage and excess affect the growth and development of a plant directly and, consequently, its yield and quality. In India, however, rainfall is notoriously capricious, causing floods and droughts alternately. Its frequency distribution and amount are not in accordance with the needs of the crops. Artificial water supply through irrigation on one occasion, and the removal of excess water

What effect does water scarcity have on food production?
Water scarcity has a huge impact on food production. Without water people do not have a means of watering their crops and, therefore, to provide food for the fast growing population. According to theInternational Water Management Institute , agriculture, which accounts for about 70% of global water withdrawals, is constantly competing with domestic, industrial and environmental uses for a scarce water supply. In attempts to fix this ever growing problem, many have tried to form more effective methods of water management.
1. One such method is irrigation management. Many of the irrigation systems in place do not use the water in the most efficient way. This causes more water than necessary to be used or for there not to be enough water to ensure healthy crops. Irrigation management works to upgrade and maintain irrigation systems, such as groundwater irrigation, that are already in place and expands the areas of irrigation to increase the amount of crops being

Another method is water management for rainfed agriculture. Rainfed agriculture is the most common method of agriculture in developing nations. According to the book,Rainfed Agriculture: Unlocking the Potential, 80% of the land farmed around the world is rainfed and it "contributes about 58% to the global food basket" (xiii). Some techniques in water management for rainfed agriculture include the use ofsupplemental irrigation and water harvesting techniques, such as rain catchment systems and weirs or sand dams. These techniques help provide much needed water to areas where rainfall is inconsistent. Having this water helps to increase the number and quality of the crops
