"at a global average, 1,000-4,000 liters of water is consumed by the biomass needed to produce one liter of biofuel"
Global Warming right now is causing drought in many parts of the world. The extensive use of water needed for biofuel processing would only aggravate the situation. Higher temperatures mean more rapid evaporation of water used for agriculture lands and in reservoirs or lakes.
Extensive evaporation of water means that large amounts of energy become available from moist warm air in the atmosphere and may suddenly be released during storms and result in flooding. The evaporation-storm-flood cycle becomes more intensive and is not conducive to growing of crops. Although the same amount of water is evaporated as is returned to the earth, the intensity and length of the evaporation which is drying up the land and causing drought, as well as the brief fall of torrential rains does not help the farmer.
The result of the acceleration and intensification of the evaporation-condensation-precipitation cycle is that although increased amounts of water are participating in the cycle itself, more water will be required to sustain crops during the extended drought condition time presently being sustained by Global Warming higher temperatures.
Basically, the vapor phase of the water is emphasized at the expense of ground surface water.
The additional requirements of water for biofuel in countries already suffering from water depletion serve only to strain an already existing over-burdened water demand condition.
