In 1993 the Board of the World Bankendorsed a Water Resources Management Policy Paper (WRMPP).In that paper, and in this Strategy, water resourcesmanagement comprises the institutional framework (legal,regulatory and organizational roles), management instruments(regulatory and financial), and the development, maintenanceand operation of infrastructure (including water storagestructures and conveyance, wastewater treatment, andwatershed protection). The 1993 Policy Paper reflected thebroad global consensus that was forged during the Rio EarthSummit of 1992. This consensus stated that modern waterresources management should be based on three fundamentalprinciples (known as the Dublin Principles). First is theecological principle which argues that independentmanagement of water by different water-using sectors is notappropriate, that the river basin should be the unit ofanalysis, that land and water need to be managed togetherand that much greater attention needs to be paid to theenvironment. Second is the institutional principle, whichargues that water resources management is best done when allstakeholders participate, including the state, the privatesector and civil society; that women need to be included;and that resource management should respect the principle ofsubsidiarity, with actions taken at the lowest appropriatelevel. Third is the instrument principle, which argues thatwater is a scarce resource and that greater use needs to bemade of incentives and economic principles in improvingallocation and enhancing quality.
