The integrated management of water resources (IMWR) has captured the imagination of researchers, professionals, governmental departments and research institutions since the beginning of the 20th Century. However, it was not until the last few decades that IMWR began dominating the discussion about the management and politics of the water resources. Currently, IMWR holds an important place among academic publications, reports and initiatives of important international organisations, such as the Agenda 21 of PNUMA, the World Congress about Sustainable Development of the UN in 2002 and other global events and publications.
Despite the fact that there are over thirty definitions of IMWR that compete among themselves, the concept is generally promoted as a way to deliver approached that allow to reach a development of the limited water resources, in an efficient, equitable and sustainable way. More specifically, more than a group of substantial contents, IMWR is considered as “a process that promoted in a coordinated wat the development and management of water, the earth and related resources, with the objective of maximizing the economic and social wellbeing in a equitable way without compromising the vital systems.” Recently, IMWR has been understood as a process that seeks water security, which can be conceived as the availability of sustainable and adequate quantities and qualities for society and resilient ecosystems, facing uncertain global changes.
