OVERVIEW

Summary of CPWF Research in the Mekong River Basin



Women and DamsThe Mekong River is one of the most bio-diverse rivers in the world, second only to the Amazon. The river rises in the Tibetan Plateau of the Himalayas and flows through three provinces of China, then Myanmar, Lao PDR, Thailand, Cambodia, and Vietnam all the way to the South China Sea.

About 70 million people live in the basin, and many of them depend on the river for food and income. However, during the past couple of decades, the region has experienced an unprecedented surge in hydropower development. In 2010, more than 3,200 MW of hydropower capacity, about a tenth of the region’s total potential, had been installed on the Mekong River’s tributaries. Many more dams are either planned or currently under construction.

The debate on hydropower development in the region is contentious and highly political. Major tensions revolve around the shift from sustenance agriculture to an economy based heavily on natural resources-based sectors, most notably hydropower. Particularly the question of how to distribute the costs and benefits of hydropower is a point of discussion. The main players in the debate are Learning by Seeinggovernments, hydropower developers, finance institutions, non-government organizations, and, to a lesser extent, civil society groups.

CPWF has worked in the Mekong River basin since 2004. From 2004 to 2008, the program implemented thirteen projects across the region. With the launch of its second phase (2009-2013), CPWF narrowed in the scope of its research to focus primarily on how to optimize the use of reservoirs and foster sustainable hydropower in support of poverty reduction and sustainable development.

One of CPWF’s major achievements in the region was to establishes spaces for dialogue between stakeholders, who in the past did not engage in fruitful exchanges, and to input new knowledge into this dialogue. CPWF contributed to creating conditions under which sustainable hydropower in the Mekong region is a possibility.

PUBLICATIONS

State of Knowledge Series (Briefs)



The State of Knowledge Series papers are easy-to-read reviews of the state of knowledge about a subject relevant to Mekong hydropower development. They are meant to be an unbiased appraisal of what we know (and don’t know) about a subject. The four State of Knowledge papers cover the following topics: Mekong fisheries, Mekong sediment basics, corporate social responsibility in Mekong hydropower development, and China’s influence on hydropower development in the Lancang River and lower Mekong River basin.

Fishery productivity and its contribution to overall agricultural production in the Lower Mekong River Basin (Working paper)



In the Mekong, fishery production and value have been the subject of many studies and some data are available from national and international statistical databases. None of these, however, offer a reliable, consistent set of data on the spatial and temporal trends at a similar level of resolution across the basin. This study combined official statistics with several consumption-based estimates to examine the spatial and temporal trends in production and value of capture fish and aquaculture.

Rebutting extremism: a comment on the debate surrounding the Xayaburi Dam in Laos



You can’t go pouring 400,000 tonnes of concrete across a river and imagine that things won’t change. But extreme perspectives on hydropower only serve to harden people’s positions. CPWF’s research in the Mekong identified a multiplicity of ways in which dams can reinforce livelihoods, for example by enabling the development of rice-fish production systems; how cascades can be better managed; how trans-boundary institutions are needed to cope with the cumulative impacts of dams; and how hydropower decision-making processes can be opened up to accommodate many different perspectives thereby improving dam design and operation.

Women and Dams



The impacts from the construction of a dam on women are numerous and will vary according to the different relocation sites. What is certain is that, while the construction of a dam is often a catastrophe for anyone in the community, the effect on women is more severe than the one suffered by men.

Water, Food and Energy: A Back-of-Envelope Analysis



Against a backdrop of changing climates, dams have considerable potential for storing water, and for contributing to agriculture. Yet, over 71% of the world’s dams are for single purpose only (50% for irrigation, 18% for hydropower). What matters about dams is where they’re placed (it’s always the lowest one in a reach that matters for the system as a whole), and their cumulative impact.
