Preliminary Design Guidance for Proposed Mainstream Dams in the Lower Mekong River Basin (PDG)

The new Preliminary Design Guidance is an updated version of the original PDG introduced in 2009. It incorporates not only what the MRC Member Countries have learnt from their own experience with hydropower, but also from examples and best practices around the world. It also includes the most current knowledge regarding design criteria, science and technology. While the older PDG spanned this range of construction and operation elements (hydraulics; sediment transport; geomorphology; water quality; aquatic ecology; fish and fisheries; dam safety; and navigation), the new PDG now includes hydrology and socio-economic impact to reflect the greater attention paid today to riparian communities and riverine livelihoods.

Guidelines for Transboundary Environmental Impact Assessment in the Lower Mekong River Basin (TbEIA)

The Guidelines for Transboundary Environmental Impact Assessment in the Lower Mekong River Basin (TbEIA) is designed as a flexible document with perspective of its further elaboration based on gradually accumulated experience of Member Countries with a TbEIA application. It is also designed as a supporting tool applicable with respect to the different national EIA legislation systems in Member Countries. It builds on and supplements five MRC procedures, including the Procedures for Notification, Prior Consultation and Agreement; Procedures for Data and Information Exchange and Sharing; Procedures for Water Use Monitoring; Procedures for Maintenance of Flows on the Mainstream, and Procedures for Water Quality in addressing potential transboundary environmental impacts of development projects.

Handbook on Mainstreaming Gender into the Mekong River Commission’s Core Functions and Activities: A Guidebook for a Gender-Responsive and Resilient Lower Mekong River Basin

The Handbook for Gender Mainstreaming into the MRC Core Functions and Activities offers a supporting tool – or a guiding note – to assist the MRC to effectively integrate a gender perspective into all aspects of its work, from the development, update and application of strategic tools, procedures, normative guidelines, studies, and organizational strengthening to designing and advocating for joint actions. It also provides a working aid to integrate gender perspectives during the course of the BDS 2021–2030 and SP 2021-2025 implementation, and beyond

The status and trends of riverine plastic pollution in the Lower Mekong River Basin

This report explains the status and trends of plastic waste pollution in the Lower Mekong River Basin from the perspectives of plastic pollution itself as well as the frameworks and capacity of each Member Country to address the issues of plastic pollution. The report estimates that in 2020, its four countries had produced about 8 million tons of plastic waste – of which, some 70% to 90% were plastic bottles, plastic bags and Styrofoam. Yet this debris does more than adversely affect the Mekong and its tributaries.

Joint Environmental Monitoring Programme at Two Mekong Mainstream Dams: The Don Sahong and Xayaburi Hydropower Projects

The report provides an overview of activities conducted and resulting recommendations from monitoring two mainstream dams: Don Sahong and Xayaburi hydropower projects. It summarizes the pilot monitoring results from the first pilot site report for each hydropower project and the Combined Annual Report in a way that illustrates how findings in hydrology, sediment, water quality, aquatic ecology, and fisheries can be interpreted together. Based on the findings, it provides some initial suggestions for mitigation and adaptive management of construction and operation of hydropower projects. It also concludes with recommendations for revisions to the guidelines and monitoring protocols that can then be incorporated into the JEM Programme document.

Social Impact Monitoring and Vulnerability Assessment (SIMVA) 2018

SIMVA 2018 is the third survey of its type and was conducted in the same sites and used the same methods of collecting primary household and village data, as the SIMVA 2014 and 2011 exercises. Covering 2,800 households in 200 villages the 2018 survey shows that communities in the Mekong mainstream corridor were still dependent on the river resources for their livelihoods, income, and well-being. As such, they are still vulnerable to changes in the Mekong water resources. However, their overall dependency has decreased with other, non-water resources-related livelihood activities playing increasingly important roles. From 2014 to 2018 the percentage of households engaging in fishing decreased across the region from 50% to approximately 37%. The study also indicates growing incidence of flooding, possibly as a result of climate change and other factors, including water infrastructure development. Government support in livelihood diversification and disaster coping strategies is essential and there is much room for improvement in this regard.

Status and Trends of Fish Abundance and Diversity in the Lower Mekong Basin during 2007–2018

The report is the first ever large-scale study to consider both spatial and temporal variations of fish abundance and diversity in the LMB, using the MRC’s long-term fisheries monitoring data. The monitoring was conducted daily between 2007 and 2018 by professional fishers at 38 stations along the Mekong mainstream and its major tributaries. But only 25 sites were selected for the study due to incomplete data. Eleven of the 25 monitoring stations were in Cambodia, four in Lao PDR, and five each in Thailand and Viet Nam. The study found 617 fish species, belonging to 21 order and 80 families in the LMB from 2007 to 2018. Some 37,530,460 individuals, corresponding to 1,095,848 Kg of fishes were collected. Temporally, both fish diversity and catch have increased during the survey period in the Tonle Sap and the Mekong upstream in southern Laos and Thailand, informing the high diversity of these areas and that sampling effort is still growing.

Mekong Strategy for Basin-wide Environmental Management for Environmental Assets of Regional Importance 2021–2025

The Mekong Strategy for Basin-wide Environmental Management for Environmental Assets of Regional Importance (SBEM) is a cooperative regional strategy to protect environmental and ecological assets, including those providing ecosystem services in the basin. It provides an opportunity to implement a cooperative strategy where capacity can be built, and best management practices and information can be shared. Ultimately, the SBEM will establish a permanent regional network of environmental assets of regional importance within the LMB, which will be protected and managed for generations to come.
