The charts show the global average water footprint/requirement for the production of one tonne of product (in cubic metres); per kilocalorie (per litre); and per gram of … The amount of precipitation falling on land is almost 110 000 km3 per year. By 2050, feeding a planet of 9 billion people will require an estimated 50 percent increase in agricultural production and a 15 percent increase in water withdrawals. The researchers also used past land-use data to create maps showing how agriculture has spread over the centuries. About 56 percent of this amount is evapotranspired by forests and natural landscapes and 5 percent by rainfed agriculture. Only 20% of the land area is naturally arable. Globally, the largest water use happens in agriculture sector, primarily for irrigation. Growing of plants with nutrients and water without the use of soil.

We have had incredible success using them in a filtration application that grow high yield bush varieties of vegetables vertically using sustainable medium using less water. A new WRI analysis shows just how much tension exists between those two essential resources.. A new interactive map from WRI’s Aqueduct project reveals that more than 25 percent of the world’s agriculture is grown in areas of high water stress. Aquaponics, a system of farming that uses no soil, also uses far less water than traditional agriculture. Agriculture accounts for over two-thirds of the world's water withdrawal, yet in the future this share is likely to come under increasing pressure from other sectors with greater purchasing power. Vegetables taste good when we are truly hungry. In many drier countries, agricultural water use accounts for more than 90 per cent of total withdrawals.

Belgium, for instance, consumes 80% of the water … This means that what we eat is more important than how much we eat in determining the amount of land required to produce our food. That fact suggests that the biggest consumer of water is meat and dairy production. Boiled rice hulls ( sink in water) soaked in a manure tea could be used to provide nitrates, aeration and moisture in a commercial application as a soil amendment and will help to utilize water. 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. Throughout the world, irrigation (water for agriculture, or growing crops) is probably the most important use of water (except for drinking and washing a smelly dog, perhaps). The remaining 39 percent or 43 000 km3 per year is converted to surface runoff (feeding rivers and lakes) and groundwater (feeding aquifers).
