Abstract

AbstractIntegrated Water Resources Management (IWRM) is increasingly important due to water scarcity, population growth, climate change, and deterioration of resource quality. IWRM requires analyti...

Highlights

Integrated water resources management (IWRM), as defined by the Global Water Partnership (GWP 2004), recognizes the interconnection between people, ecosystems, and hydrology, and seeks to promote a coordinated management of natural resources that maximizes economic and social welfare in an equitable manner without compromising the sustainability of ecosystems
Using the models and automated systems described in the papers analyzed, a quantitative analysis was conducted regarding the consideration of the IWRM concepts by the tools provided
AQUATOOL was one of the main instruments used in Spain to analyze water quantity and quality aspects of water resources systems for the compliance with European Water Framework Directive SWAT can be used to build models to evaluate the effects of alternative management decisions on water resources and non-point source pollution in large river basins Using a multi-objective evolutionary algorithm, the results showed that a Pareto front was formed, providing different satisfactory solutions for users to choose according to their specific objectives

Summary

Introduction

Integrated water resources management (IWRM), as defined by the Global Water Partnership (GWP 2004), recognizes the interconnection between people, ecosystems, and hydrology, and seeks to promote a coordinated management of natural resources (water, land, and others) that maximizes economic and social welfare in an equitable manner without compromising the sustainability of ecosystems. Adopted as a guideline by most governments in developed countries, IWRM policies have been reported to be difficult to implement. This is true in countries under development (Merrey 2008). In these countries, there is an increasing pressure on often scarce water supplies, exacerbated by the combined effects of climate change, population growth, and increasing urbanization. There is already evidence of the effects of climate change on the availability and demand for food, energy, and water, especially in fast-growing countries (Perrone and Hornberger 2014; Schornagel et al 2012; Shah et al 2009; Voinov and Cardwell 2009; WWAP 2012)
