Fertilizer chemicals and manure in the water reduces oxygen levels in the water resulting to loss of aquatic life and destruction of marine ecosystems like freshwater lakes, rivers and coral reefs. Blackwell, Oxford, pp 113–141 Google Scholar These ‘sustainable agricultural practices’ help improve soil health, water quality, and protect watersheds. The World Wild Fund (WWF) statistical estimates show that out of the 2,500 trillion liters of water used in agriculture each year, about 1,500 trillion liters go to waste. Commercial, Industrial, Agricultural & Electricity Water Use. Current agricultural practices are typically inefficient in water use. United Nations Development Programme, 2013 Agriculture is a significant water user in Europe, accounting for around 33% of total water use. The rest is frozen in glaciers or hidden too deep underground. Plants require water for photosynthesis, growth, and reproduction. In the United States, for example, agriculture accounts for over 80% of water consumption (USDA, 2010). While agriculture accounts for only 2 percent of California's economy, as much as 80 percent of California's water for human use goes to agriculture. Agriculture 4.0 will no longer depend on applying water, fertilizers, and pesticides uniformly across entire fields. In agriculture, water is used to grow fruits, vegetables, and raise livestock. Sustainable agriculture must nurture healthy ecosystems and support the sustainable management of land, water and natural resources, while ensuring world food security. As much as organic farming is more costly, it produces healthier foods that are free from chemicals. Water sustainability is, therefore, at the core of GEF strategy until 2020. Industrial agriculture’s use of water is a cycle of overuse, waste and pollution. Aquifers are increasingly losing their ability to hold water due to over-exploitation and reduction of forested land to facilitate recharging of ground water. It’s easy to forget that we also use water in ways we don't see every day. Lima, according to the World Bank data, is the second biggest city in the world built in a desert.

This is of great concern considering the fact that the source of water is limited. Such increase in global freshwater consumption has led to the depletion of over half of the world’s largest aquifers, and is a problem that will likely deteriorate as demand grows. He spent a large portion of his adolescence and early twenties doing wrestling for his high school and college. Unit 1.3 focuses on case studies of unsustainable water use in agriculture. According to Liebig’s law of the minimum, productivity and growth of crops are increased by the scarcest and rarest trace mineral and not by the mineral whose amounts are huge. Greenhouse gas emissions Various aspects of soy production generate greenhouse gases that contribute to climate change. Learn More about Irrigation PROTECTION OF WATER FOR AGRICULTURAL USE. In some nations lacking freshwater, desalination has provided an adequate water supply for many years. Water is used to grow our food, manufacture our favorite goods, and keep our businesses running smoothly. Governments should consider encouraging people to harvest rain water and include rainwater harvesting infrastructure during construction, as a way of reducing water wastage. Close to 100% of our vegetable suppliers, including tomato suppliers, now comply with our Code. Per capita water availability by region, 1950-2000, (Source: N.B. As populations and economies expand in growth, competition for limited water resources tends to intensify leading to conflicts among water users. Despite its limited supply, there is a widespread tendency to misuse water. Failure to address unsustainable use of water now will mean greater struggles in the future to achieve goals in a myriad of other areas. As children grow up, they need to be taught how to take care of the environment. “We have a basis for making policy and investment decisions now,” said Knut Roland Sundstrom, Climate Change Specialist for the GEF. 4. A Agriculture claims 80-90% of water use in the U.S., and has depleted groundwater in parts of the Great Plains by up to 30%. This dissertation assesses both current use of groundwater for country- to global-scale agriculture, and looks at the future of groundwater. Over the past 20 years, the expansion of agriculture has funded infrastructure development that now supports 3 million people. International disputes associated with unsustainable water use. Unsustainable groundwater use results in water-level decline, reduced streamflow, and low water quality, jeopardizing the livelihood of effected communities. Though some of these losses are basically inevitable, often the excess water tends to seep back in to the ground resulting to salinity and clogging. Reduce water use in agriculture. The World Wild Fund (WWF) statistical estimates show that out of the 2,500 trillion liters of water used in agriculture each year, about 1,500 trillion liters go to waste. Additionally, unsustainable water use in irrigated systems can strain aquifers, such as the Ogallala Aquifer in North America and the Guarani Aquifer in South America. Consumers also should consider buying from small local farms as opposed to larger farms whose pesticide usage is extremely high, Farmers should be encouraged to adopt sustainable agricultural practices that are friendly to the environment. We will develop comprehensive plans with our suppliers and partners to reduce the water used to grow our crops in water-scarce countries. To be sustainable, agriculture must meet the needs of present and future generations for its products and services, while ensuring profitability, environmental health and social and economic equity. For Bogota, the Colombian capital, future water supply for its 7 million residents depends on the sustainable management of high-mountain wetlands and ecosystems in the Chingaza-Sumapaz-Guerrero corridor. Because water pricing is often viewed as a mechanism to promote a more efficient use of water resources, an international agreement on water valuation is sometime considered to be crucial to the achievement of an efficient and sustainable global water use, a point that has been discussed at the World Water Forum in the last two decades (3, 22).
