Water Shortages Threaten Food Supplies and Regional Peace

Water shortage reduced global food supply by more than 10%. A new book from the Worldwatch Institute reports that if these shortages are left unresolved, it may lead to hunger, civil war, even water warfare. Irrigation accounts for two-thirds of the world's water usage, but less than half of it reaches the root of the plant. "If we do not increase the productivity of irrigation water, there is not enough water to maintain crop production in major food production areas," says Sandra Postel, author of Sand of Pillar of Sand.

This evaluation noted that in South America and the Caribbean, water scarcity and competition will be faced as the runoff and groundwater recharge are reduced. In addition, reducing the amount of snow will threaten the supply of similar climate to the southwestern United States if you reduce the amount of snow. Hope of light: Individuals, cities and countries will conserve water in various ways and take an important step for water safety. Earlier this year, Cape Town in South Africa could shut down the municipal water supply system, but due to the main protection work, it delayed "zero day" (at least so far). It may also be helpful to transfer water intensive crops from areas with strong water pressure

People in many parts of the world are short of water. These are caused by depletion of groundwater sources known as aquifers, insufficient rainfall due to drought, or water supply contamination. The World Health Organization (WHO) estimates that 6 billion people do not have adequate sanitation facilities. More than 5 million people die each year using contaminated water to drink, cook, and wash. People can protect and protect water supply in various ways. Individuals can limit the amount of water used by fixing the leak tap, shortening the shower, planting a plant resistant to drought, and purchasing low water utensils. Governments, businesses, nonprofit organizations can help developing countries build medical facilities

Optimize water efficiency. In some parts of the world, water supply is expected to be threatened by climate change, but water management strategies such as drip irrigation can conserve water and protect vulnerable crops from water shortages. In order to evaluate the effectiveness of these practices agriculturalists often calculate crop yield or water productivity per unit of water. Water, also known as achieving 'crop increase per drop', is an improved varieties, plant nutrition, irrigation methods based on real-time crop requirements, better drought and heat resistance of crops grown in the rainwater system It can be improved through sex. productivity
