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.

Proceedings of the 1st ASEAN-MRC Water Security Dialogue: Solutions for a Changing Region

This is the proceedings of the 1st ASEAN–MRC Water Security Dialogue, organized on 19–20 August 2021. It captures key messages from the Dialogue, which serves as a platform to exchange novel ideas and identify possible areas for collaboration to further strengthen regional and local capacities in addressing water scarcity, water pollution, and water-related disaster risks, such as flood and drought. The inaugural ASEAN–MRC Water Security Dialogue tables three thematic solutions related to policy, technology, and partnership that can help countries in the Mekong and broader ASEAN address existential water security challenges that confront the region.

Mekong Low Flow and Drought Conditions in 2019–2021
Conditions in 2019–2021: Hydrological Conditions in the Lower Mekong River Basin (Technical Report)

This technical report unravels the underlying drivers of the extremely low flows and drought based on an analysis of the available data the MRC has collected. Based on the findings, it suggests potential measures to address and mitigate the impacts of the hydrological droughts and storage on the Basin’s people.

Annual Mekong Hydrology, Flood and Drought Report 2019: Drought in the Lower Mekong Basin

This paper reports on the condition of the Basin in 2019, including its hydrology/water flow, flood and drought. The year saw recorded unprecedented flow conditions in the Mekong mainstream and from tributaries. Erratic climatic fluctuations were also found, ranging from extreme dry to extreme wet within short periods of time. The report ends with key recommendations, looking forward.

Social Impact Monitoring and Vulnerability Assessment (SIMVA) 2018
Report on 2018 baseline survey of the Lower Mekong mainstream and floodplain areas

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.

Situation Report on Dry Season Hydrological Conditions in the Lower Mekong River Basin: November 2020–May 2021

This Situation Report presents a preliminary analysis of the Lower Mekong River Basin hydro-meteorological conditions over the 2020–2021 dry season. It shows fluctuations in water levels in the upper reaches of the Mekong mainstream in Lao PDR and Thailand, as well as low water volume stored in the Tonle Sap Lake. Rainfall in April–May was the highest on record for these months for the last 18 years in places. Overall, flows in the Mekong in the first five months of 2021 were also higher than the long-term average, except for December 2020 where flows in the Mekong mainstream were closer to normal. But river flows did not increase significantly.

Technical Guidelines on the Implementation of the Procedures for Water Quality

The Technical Guidelines facilitates the implementation of the Procedures for Water Quality (PWQ) – one of the five Mekong Agreement’s Procedural Rules. The objective of the PWQ is to “establish a cooperative framework for the maintenance of acceptable/good water quality to promote the sustainable development of the Mekong River Basin.”

Situation Report on Hydrological Conditions in the Lower Mekong River Basin in July–December 2020

The report presents a preliminary analysis of the hydro-meteorological conditions in the Lower Mekong River Basin (LMB) in July–December 2020. The report suggests that the LMB experience a second year of low flows at the beginning and a delayed onset of the wet season in 2020, with some parts experiencing low flows and appearing to be worse than that in 2019.
