The Mekong River Basin, site of the biggest inland fishery in the world, is undergoing massive hydropower development. Planned dams will block critical fish migration routes between the river's downstream floodplains and upstream tributaries. Here we estimate fish biomass and biodiversity losses in numerous damming scenarios using a simple ecological model of fish migration. Our framework allows detailing trade-offs between dam locations, power production, and impacts on fish resources. We find…

Hydropower Development and the Loss of Fisheries in the Mekong River Basin

Development of large scale hydropower is proceeding rapidly in the Mekong basin without adequate consideration of the severe and cumulative impacts the dams and reservoirs will, and are already

The Mekong River: trading off hydropower, fish, and food

Hydropower dam construction is currently focused in Africa, Asia, and Latin America to increase electricity supplies, yet the negative environmental and social impacts are extensive. The planned

Impacts of Mainstream Hydropower Dams on Fisheries and Agriculture in Lower Mekong Basin

The riverine ecosystems of the Mekong River Basin possess the world’s most productive inland fishery and provide highly productive food crops for millions of people annually. The development of

Designing river flows to improve food security futures in the Lower Mekong Basin

It is hypothesized that high fisheries yields are driven by measurable attributes of hydrologic variability, and that these relationships can be used to design and implement future flow regimes that improve fisheries yield through control of impending hydropower operations.

Transboundary threats in the Mekong basin: protecting a crucial fishery

The Mekong River is a source of fresh water, food, energy, biodiversity, and cultural heritage to more than 70 million people living throughout its basin. Flowing from its headwaters in southern

Addressing fish-passage issues at hydropower and irrigation infrastructure projects in Indonesia

Development activities threaten the long-term sustainability of tropical floodplain systems. The construction of dams, weirs, irrigation infrastructure and regulators affect connectivity among

Linking freshwater fishery management to global food security and biodiversity conservation

A map of the world’s riverine fisheries is developed and it is found that freshwater fisheries provide the equivalent of all dietary animal protein for 158 million people, revealing that fishing pressure is most intense in rivers where potential impacts on biodiversity are highest.



Fish Migration, Dams, and Loss of Ecosystem Services in the Mekong Basin

It is determined that dams on the Mekong mainstem and major tributaries will have a major impact on the basin’s fisheries and the people who depend upon them for food and income, and major investment is required in innovative technology to reduce the loss of ecosystem services.

Dams and fisheries in the Mekong Basin

This paper draws on approaches in ecology, biology and policy analysis to examine the tensions between dams and fisheries in the Lower Mekong Basin. We review the exceptional importance of Mekong

How much of the Mekong fish catch is at risk from mainstream dam development

There are currently 11 proposals for dams to be built on the mainstream of the Mekong River in countries downstream from China (see map on page 3 and table on pages 6-7). Planning agencies need to be

Mekong Hydropower Development

Decisions on this initial proposal expected over the coming months by the MRC countries may contribute to promoting high-impact hydropower development or to a movement toward integrated, transboundary river-basin management that could serve as a model for other rivers.

Potential Effects of Dams on Migratory Fish in the Mekong River: Lessons from Salmon in the Fraser and Columbia Rivers

Significant effects of development on salmon in the Columbia River are found and prompt action is needed by governments and fisheries managers to plan Mekong water resource development wisely to prevent impacts to the world’s most productive inland fisheries, and food security and employment opportunities.

Blue harvest: inland fisheries as an ecosystem service

Global food production has increased greatly in recent years and rural livelihoods are much improved in many regions. Yet, despite this clear progress rural poverty and food insecurity remain deeply

Fish environmental guilds as a tool for assessment of ecological condition of rivers

The form, hydrology and functioning of rivers worldwide have been increasingly modified by a range of human activities. The impacts of these changes on the fish faunas of rivers need to be assessed

The report provides a basis for understanding the consequences of human intervention to the natural flow regime of the river system on fish migration and thereby on the fisheries of the Lower Mekong

Fragmentation and Flow Regulation of the World's Large River Systems

A global overview of dam-based impacts on large river systems shows that over half (172 out of 292) are affected by dams, including the eight most biogeographically diverse catchments, which can be used to identify ecological risks associated with further impacts onLarge river systems.

Fish Migrations of the Lower Mekong River Basin: Implications for Development, Planning and Environmental Management

The report identifies some key features of the Mekong River ecosystem that are important for the maintenance of migratory fishes and their habitats. The report further discusses ways in which
