Integrated Water Resources Management in the 21st Century: by Pedro Martinez-Santos, Maite M. Aldaya, M. Ramón Llamas

By Pedro Martinez-Santos, Maite M. Aldaya, M. Ramón Llamas

Built-in water assets administration advocates a coordinated procedure for handling water assets in a fashion that balances social and fiscal wishes with quandary for the surroundings. whereas in all probability necessary, built-in water administration can be debatable. Supporters think that the multi-dimensional nature of water can basically be understood and controlled from a holistic standpoint, whereas critics frequently argue that built-in water administration lacks suffi ciently well-defi ned ideas for its functional implementation. This e-book, written by means of teachers, clients and practitioners, presents a down-to-earth method of the correct of built-in water assets administration, drawing from conceptual frameworks and real-life perform to spot the major points which are but to be resolved. As such, it examines the function of water accounting, meals alternate, environmental externalities and intangible values as key points whose attention can help the water administration group circulate ahead. total, built-in water assets administration is appeared to be an invaluable utopia, whose price lies extra within the steps that have to be taken to make it a truth than in attaining its ever-elusive finish aim.

This promise plus the backing of important international organizations has allowed IWRM ideals to acquire a near monopoly on water management discourse.

The virtual water trade can efficiently redistribute global water and partially help to address the impacts of production. At present, however, this option is far from being fully exploited due to the absence of a more water friendly international trade regime with equal access to global markets. , 2010b). , 2006). Countries with low-income levels are minor participants. As Allan (2006) points out, socio-economic development is a prerequisite to access virtual water in the global system. Besides, other factors are also interrelated with global green water trade such as availability of land, labor, technology, the costs of engaging in trade, the potential for further increases in the productivity of soil water and irrigation water, national food policies and international trade agreements.

It then provides a set of case studies examining solutions to water problems whose methods run counter to IWRM. The case studies include a non-basin scale approach to reduce transboundary conflict in Central Asia, a non-price solution to groundwater overdraft in western India, and non-participatory methods in China to move low-value agricultural water to higher value urban uses without decreasing agricultural production. The overall point of the chapter is not to criticize IWRM. Rather it is to highlight that IWRM principles are simply one option among many for improving the way we use scarce water resources.
