-- Solutions available to cities and industry won't work for agriculture. Desalination and recycling may present viable alternatives to municipalities and industry where water can be piped between sources and demand centers. But it's generally impossible to recapture sufficient amounts of evaporation in agricultural regions, and farms are too large, cost sensitive, and distant from oceans for desalination to work. -- The only option left is for agriculture to increase water efficiency. Existing technologies can bring agricultural water demand within sustainable levels in many scenarios. Efficiency improvements from drip and smart irrigation, for example, can reduce consumption; while genetically modified crops can improve yields, require less water and resist drought. Optimal use of fertilizer and pesticides, plastic mulches, and more efficient food distribution can also help minimize water use. -- Water needs will limit large-scale adoption of some biofuels. If long- term projections for biofuels from organizations like the U.S. Energy Information Administration hold true, crops grown for biofuels would account for 15% of agricultural water withdrawals in 2050 -- even accounting for a major shift to lower-water feedstocks like cellulosic and algae biomass. This figure could be enough to tip the scales to unsustainability, even with adoption of water-saving agricultural technologies. As a result, for biofuels to boom, the shift away from current feedstocks -- such as corn, sugar, and soy -- will have to be even more thorough than now projected."Traditionally, agriculture has been reluctant to try new technologies. But improved crop yields present financial incentives for farmers," said LoCascio. "And water costs could become another driver promoting adoption of water conservation technologies."
