"Water Availability and Global Land Use Change"
by Liu, Jing, Farzad Taheripour and Thomas Hertel

The dual stressors of surging water demand and climate change induced variable water supply signal that we are entering an era of water scarcity. Under an average economic growth scenario with no efficiency gains, global water requirements by 2030 would grow from 4,500 billion m3 today to 6,900 billion m3, which is a full 40 percent above current accessible, reliable supply (Addams, et al. 2009). In addition, water’s two fundamental functions, the role as an essential requirement for life and its use as an economic input, are increasingly in conflict. If assume that water for agriculture is low-priority use and the entire water demand-supply gap is closed by cutting down irrigation, the impact of water deficit on agriculture can be sizable given the fact that agriculture accounts for up to 70 percent of global water withdraw (FAO, Agriculture, food and water 2003).
