Integrated Water Resources Management: What is it and why is it used? Chris White URS, London Discussion Paper 1324 June 2013 This article looks at the use of the Integrated Water Resource Management (IWRM) framework in water management. The author looks at the successes and challenges of implementing IWRM in practice, arguing that its flexibility is both an advantage and a disadvantage. these issues are interconnected; subsidised water prices, for example, can lead to rising water demand which may reduce the quantity of water in the environment thereby leading to an increase in the concentration of pollutants and a decline in water quality. The Global Water Forum publishes discussion papers to share the insights and knowledge contained within our online articles. The articles are contributed by experts in the field and provide: original academic research; unique, informed insights and arguments; evaluations of water policies and projects; as well as concise overviews and explanations of complex topics. We encourage our readers to engage in discussion with our contributing authors through the GWF website. Keywords: Integrated Water Resource Management, successes, challenges, flexibility Due to the interrelated nature of water issues, the use of particular economic or policy instruments can create trade-offs. Purchasing water access rights to secure environmental flows, for example, may be a cost-effective method of increasing the amount of water in the but reduced water extractions may also negatively impact small towns In order to deal with the complexity of water environment, and communities dependent on irrigated agriculture. management issues, discussion over water resources is typically separated into distinct In order for water security to be managed topics such as Economics, Water Quality, and effectively, the use of economic and policy the Environment. In reality, however, each of instruments cannot be considered in isolation, Suggested Citation: White, C.

In order to environmental characteristics, there is no deal with this complexity and coordinate single blueprint for IWRM and it can be policy effectively, it is often argued that adapted to resolve the problems faced in each economic and policy instruments should be local context.3 Effective water and political context, and used as part of a wider integrated water resource management (IWRM) framework. As a result, the goals of IWRM vary across countries and different weights are placed on IWRM is a framework designed to improve the importance of economic, environmental, the management of water resources based on and social impacts: Chile, for instance, four key principles adopted at the 1992 Dublin typically Conference on Water and the Rio de Janeiro economic efficiency, whereas South Africa and Summit on Sustainable Development. These the Netherlands tend to place more emphasis principles hold that: (1) fresh water is a finite on social and environmental goals respectively. and vulnerable resource essential to sustain It should not, however, be thought that there life, development, and the environment; (2) are always trade-offs between these goals, and water development and management should a more integrated approach to water security be approach, management can help in achieving win-win involving users, planners, and policy makers outcomes which promote more than one goal. at all levels; (3) women play a central part in Implementing a well-designed scheme for the provision, management, and safeguarding pricing water resources, for example, can of water; and (4) water has an economic value promote in all its competing uses and should be environmental benefits due to decreases in recognized as an economic good.1 water demand, and generate social benefits if based on a participatory emphasises economic the importance efficiency, of create the funds are used to expand service provision IWRM is not, therefore, a prescriptive description of how water should be managed, or are combined with subsidy schemes for low-income households. but rather it is a broad framework in which Integrated Water Resources Management: What is it and why is it used?

Some of the across countries can make IWRM difficult to benefits define, it can be broadly characterised by a incorporating number of key trends.

As such, while people may want a of such schemes is crucial to set of prescriptive solutions to resolving water Such case studies highlight the fact that IWRM can lead to more economically, socially, and environmentally sustainable solutions to complex water issues, however, it is important to note that this will not always be the case. IWRM based schemes can be issues, in reality, complex issues require complex solutions and one of the main reasons for adopting IWRM may be that its flexibility embraces and accounts for the challenges of complexity. unsuccessful5 References 1. 1.

About the Global Water Forum The Global Water Forum (GWF) is an initiative of the UNESCO Chair in Water Economics and Transboundary Governance at the Australian National University. The GWF presents knowledge and insights from leading water researchers and practitioners. The contributions generate accessible and evidence-based insights towards understanding and addressing local, regional, and global water challenges. The principal objectives of the site are to: support capacity building through knowledge sharing; provide a means for informed, unbiased discussion of potentially contentious issues; and, Integrated Water Resources Management: What is it and why is it used? provide a means for discussion of important issues that receive less attention than they deserve. To reach these goals, the GWF seeks to: present fact and evidence-based insights; make the results of academic research freely available to those outside of academia; investigate a broad range of issues within water management; and, provide a more in-depth analysis than is commonly found in public media.
