New research shows how measurements of soil moisture from space could be used to understand how much water is used for agriculture and potentially help farmers manage consumption. Efficient irrigation systems and water management practices can help maintain farm profitability in an era of increasingly limited and more costly water supplies. It accounts for an estimated 70 per cent of total freshwater withdrawals. By growing a variety of less thirsty crops, including perennial crops with deep roots, this should reduce the demand for water in agriculture. About 56 percent of this amount is evapotranspired by forests and natural landscapes and 5 percent by rainfed agriculture.
