Effect of water shortage on crop production in Afgoi distrct lower shabelle region.

The lack of appropriate access to water for human and environmental needs, which can be roughly defined as a severe and developing challenge, is becoming more widely acknowledged in many countries. As a result, the phrase "water scarcity" is frequently used in academic literature, government reports, NGOs, and international organizations like the UN and OECD to identify regions where water supplies are under stress. (White, 2012) Around 40% of people on earth reside in regions with moderate to severe water stress. According to the united nation (UN) assessment of fresh water resources, moderate stress is defined as human consumption of more than 20% of all available renewable freshwater resources, while severe stress is defined as consumption of more than 40% (Tietenberg & Lewis et al, 2012). Two-thirds of the world's population, more than 5.5 billion people, are predicted to live in regions with moderate to severe water stress by 2025 (Sharmarke, 2018) Groundwater is being used up faster than it is being supplied in China, the United States, Mexico, and India, and aquifer levels are constantly dropping. Some rivers, like the Yellow river in China and the Colorado in western America, frequently dry up before they reach the ocean. Huge lakes like the Aral Sea and Lake Chad, which were once immense, are now a small portion of their historic sizes. The number of Asian rivers' glaciers is declining (Sharmarke, 2018)
