The Global Food and Water Crisis: (Uploaded 22 October 2008)
In a paper published in the Philosophical Transactions of the Royal Society, four British scientists report that "agriculture accounts for 80-90% of all freshwater used by humans," that "most of that is in crop production," and that "in many areas, this water use is unsustainable." As a result, they say that "farmers in many countries are now faced with legislative restrictions on use of water," noting that the Chinese government "has set a target of a reduction of 20% in water use in agriculture by the year 2020," such that "if food security for the region is not to be threatened, this must be achieved without a loss in production." So how is this global food and water crisis to be met and overcome?
