The Global Water System Project, which was launched in 2003 as a joint initiative of the Earth System Science Partnership (ESSP) and Global Environmental Change (GEC) programme, epitomises global concern about the human-induced transformation of fresh water and its impact on the earth system and society. The fact is that freshwater resources are under stress, the principal driver being human activities in their various forms.

In its fourth assessment report in 2007, the Intergovernmental Panel on Climate Change (IPCC) highlighted the link between societal vulnerability and modifications of water systems. It is globally estimated that the gap between demand for and supply of fresh water may reach up to 40% by 2030 if present practices continue.
