Document Summary
Fluid intake has the biggest effect on immediate survival. Our bodies tend to have several weeks worth of reserve energy from food stores, but lack of fluid causes problems with kidney function within a few days. 70% of global fresh water is used for agricultural purposes (allouche 2010: 3). Strong link between population growth and water use: One billion people suffer hunger; two billion people exist on inadequate diets while the global population is still rapidly increasing. To meet the nutritional needs of all food production will have to double in the next 25 years. Consequently agricultural water use will increase, unless potentially offset by improvements in water and land use efficiency (bogardi et al. There is much scope for such improvement: globally, at least half of the water withdrawn for irrigation does not reach the crops for which it is intended.
