In many drier countries, agricultural water use accounts for more than 90 per cent of total withdrawals. Efficient irrigation systems and water management practices can help maintain farm profitability in an era of increasingly limited and more costly water supplies. Here are 16 interesting facts about water use by America’s farms. With beef requiring some 400 million gallons of water per ton of meat produced, experts are starting to question such heavy water expenditures. While much of this produce is consumed in America, some of it, like almonds, are mostly exported (1.1 gallon of water to grow one almond, or 6.6 gallons to grow a handful of six almonds). As per the Food and Agriculture Organization (FAO) and its AQUASTAT division, Somalia, Afghanistan, and Nepal are the top three countries to divert the highest percentage of … Gerbens-Leenes, P.W.

On average, 44% of total water abstraction in Europe is used for agriculture, 40 % for industry and energy production (cooling in power plants), and 15 % for public water supply. Aquaponics, a system of farming that uses no soil, also uses far less water than traditional agriculture. RICE AS grown in India is a water-guzzler, because farmers use on an average 15,000 litres to produce one kg of paddy, though water technologists at the Indian Agricultural Research Institute in New Delhi say no more than 600 litres is needed if proper water management techniques are followed. As we get older, our bodies tell us to eat less meat anyway. Irrigation water is essential for keeping fruits, vegetables, and grains growing to feed the world's population, and this has been a constant for thousands of years. As we said, alfalfa, grown on over a million acres in California, uses more water than any other crop.

There are 330 million acres of land used for agricultural purposes in the United States that produce an abundance of food and other products (2). Here’s a rainwater collection system that’s no-fuss — with a touch of magic. However, only 48% of it is used in Indias surface and groundwater bodies. The researchers also used past land-use data to create maps showing how agriculture has spread over the centuries. 30 to 40 percent. Also, is Australia part of East Asia & Pacific? However, freshwater—the stuff we drink, bathe in, irrigate our farm fields with—is incredibly rare. On top of the water needs for growing feed, water is needed to mix the animal feed, for maintaining the farm, and for drinking of the animals. The Netherlands might be a small country, but it's the second-largest exporter of agriculture in the world, after the United States. This means that crop and livestock production absorbed the bulk of the uses of water… Globally, agriculture accounts for 92% of the global freshwater footprint; 29% of the water in agriculture is directly or indirectly used for animal production . In agriculture, water must be of suitable quality to irrigate crops or provide drinking water for livestock. In most regions of the world, over 70 percent of freshwater is used for agriculture. Farm water may include water used in the irrigation of crops or the watering of livestock. India receives an average of 4,000 billion cubic meters of precipitation every year. A dearth of storage procedure, lack of adequate Some columnists have suggested that the real resource that’s been squandered in California is the soil.

Higher yields come from aerated microbial rich soils and by incorporating a gardening system that incorporates water filtration and evaporation to control heat would also work. Livestock directly use only 1.3 percent of that water. Belgium, for instance, consumes 80% of the water … About 56 percent of this amount is evapotranspired by forests and natural landscapes and 5 percent by rainfed agriculture. Increasing yield per unit of water used will be critical for agricultural adaptation. And much of the alfalfa grown in California isn’t fed to cattle in the U.S. but shipped to China. Of the water used in agriculture, only about half of it can be reused, because much of it evaporates or is lost during transit. About 69% of the fresh water is in form of ice cap and glacier in places like the Antarctic and Greenland ice sheet, further reducing the quantity of the available drinking water. U.S. agriculture accounts for 87 percent of all the fresh water consumed each year. Municipalities use 7%, and industry uses 3%.
