Resumen:

This chapter reviews three approaches to water management i) supply-side, ii) demand-side and, iii) integrated. Tools and applications for each approach are reviewed in order to understand their reach in the solution of water-related problems. The paper focuses on management tools which are also applicable on the scale of urban areas. Recent formulations take into account a holistic understanding of water resources that provides environmentally and socially acceptable solutions. The solutions proposed explore a combination of technologies and strategies, depending on the aims of projects, their local and national context, and the available data. The involvement of decisionmakers, stakeholders and other end-users is essential for the specification of relevant issues and the development of useful tools to support decisions. The challenges that face central and northern Mexico are reviewed. The limitations of conventional practices of water management in Mexico point to the need for a paradigm change, from increasing supply to reducing demand. The change toward more integrated management is a complex and difficult task, given the traditional dominance of centralized and technocratic management. The benefits of holistic management approaches are discussed, as are the obstacles that have limited their adoption so far. © 2009 Nova Science Publishers, Inc. All rights reserved.
