Investment Options and Associated Measures to Optimize Fisheries Production Under Changed River Conditions

This report assesses the status and trends in capture fisheries in the Lower Mekong Basin and needs for investment in their sustainability in the face of a changing river environment. It consolidates national reviews from Cambodia, Lao PDR, Thailand and Viet Nam into a regional overview highlighting key issues, proposed solutions, and investment needs aligned with existing national and regional fisheries management policies. Three potential small regional projects are identified with the aim to contribute to upcoming projects. These projects focus on improved national assessments of fisheries and incorporation of fisheries information into policy and planning; co-management of fisheries and fish habitats; and integrating the values of fisheries into climate change mitigation and adaptation strategies.

Analysis of extreme weather events and climate variability in the Lower Mekong Basin

The Government of Japan, through its ODA, supported the MRC from 2021 to 2024 to strengthen the MRC RFDMC institutional and technical capacity under the project entitled “Flood and Drought Management in the Mekong” that focuses on enhancing flood and drought monitoring, forecasting systems, and improving the dissemination of warnings and alerts. This report, one of the products of the project, addresses extreme weather events like heatwaves, cyclones, heavy rainfall, and droughts, which frequently result in economic losses, fatalities, and environmental damage in the LMB. It highlights the need to understand short-term weather conditions and long-term climate changes for more accurate forecasting. In-depth studies of historical weather and climate data could contribute to better planning, adaptation, and the improvement of forecasting models, which are essential for managing future weather risks at both national and regional levels.

Guidance for Improving Irrigation Systems to Address Climate Change and Food Security

This guidance gives a preliminary guidance for applicable irrigation techniques and technologies in the Lower Mekong Basin (LMB). This guidance was developed for the MRC Member Countries to use for mitigating impacts of climate change and natural disasters, addressing problems in irrigation sector, and improving irrigation systems in the LMB. This guidance also indicates the defects of irrigation techniques and technologies being utilized in the LMB and suggests where improvements could be made for better utilization.

Development and update of water level and discharge rating curves for the Mekong mainstream

This technical note is an update of analysis of the rating curves for mainstream and tributaries of the Mekong River for 2009-2012, published in 2013, discussing the approach and methodology of rating curve establishment. The current publication underscores the Mekong River Commission Secretariat’s (MRCS) commitment to advancing integrated data management. The MRCS adopts the Time Series Management Software, AQUARIUS, to migrate rating curve development. This shift aims to establish a centralised, easily maintainable system, ensuring a reliable source of accurate water data. The transition of rating curve development to AQUARIUS is anticipated to enhance the efficiency, accuracy, and defensibility of water data management processes.

Standardization of a vessel and waterway classification in the MRC

The “Standardize vessel and waterway classifications” is to update and harmonize different standards, rules, and regulations to uniform common standards for the development and liberalization of waterway transport on the Mekong River System. It involves analyzing technical and operational criteria for vessel classification and proposing standardized either one waterway classifications for the whole Mekong River Basin or two classifications for the upper and lower parts. It develops a proposal for waterway classification for each stretch of the Mekong River, its tributaries, and canals. In addition, a comprehensive set of regulations for vessel and waterway classification in the Mekong River Basin is prepared for implementation in the four MRC Member Countries.

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.
