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.

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.
