Long-term and Cost-effective Monitoring of Riverine Plastic Debris Pollution in the Lower Mekong River
With a recent study identified the Mekong River as one of ten rivers to contribute over 90% of plastic debris to the world’s marine environment, there is an urgent need for a reliable data and information on riverine plastic debris pollution and their impacts to the aquatic environment of Mekong River. This Riverine Macroplastic Monitoring Protocol has been developed and finalized as one of three protocols of the MRC’s Detailed Methodology for the Long-term and Cost-effective Monitoring of Riverine Plastic Debris Pollution in the Lower Mekong River Basin (LMB). The finalization of the detailed methodology was made possible through the concerted efforts and commitment of the MRC Member Countries and support of experts at national, regional and global levels, and included rigorous processes of consultations, capacity building, and piloting to ensure that the methodology is adapted to the situation of the LMB. The methodology aims to provide the much-needed data and information for an improved knowledge and understanding on the pathway and behaviors of plastic debris pollution in the LMB, from land-based sources to riverine environment, and ultimately to the marine environment. Information derived from the long-term implementation of methodology can be used to assess the effectiveness of plastic waste management the LMB.
Technical Report – Phase 1 of the Joint study on the Changing Patterns of Hydrological Conditions of the Lancang-Mekong River Basin and Adaptation Strategies
This is the 1st phase report of the Joint Study on the Changing Pattern of Hydrological Conditions of the Lancang-Mekong River Basin and Adaptation Strategies, conducted by the MRC and LMC Water Center. The report identifies two key factors that contribute to hydrological changes in the LMB. First are natural factors, including precipitation patterns, evaporation rates, soil properties and topography. Second are human activities, such as infrastructure development, water management, land cover and land-use changes. These two factors interact and influence the amount, timing and water distribution within the Basin.
Key Achievements and Impact Stories
The Annual Report 2022 opens a window onto the Mekong River Commission’s most significant achievements of 2022 and sheds light upon the progress that the MRC aims for in 2023. 2022 was the second year of implementation of the MRC Strategic Plan 2021–2025, which contributes directly to the Basin Development Strategy 2021–2030. After two difficult years slowed by the global COVID pandemic, MRC work with its four Member Countries largely returned to normal. The five Strategic Priority areas of the BDS: Environment, Social, Economic, Climate Change, and Cooperation aim to achieve 11 BDS Outcomes and 30 Outputs by 2030. More specifically, a total of 95 routine and non-routine activities are deemed necessary to achieve these Outputs. Each section of the content contained in this report then illuminates these five prioritized dimensions: the challenges being addressed, the objectives achieved and the advances yet to come.
Fish-Friendly Irrigation: Guideline on Fishway Design, Construction, Operation, Maintenance and Adjustment (Laotian)
The ‘Guidelines on Fishway Design, Construction, Operation, Maintenance and Adjustment’ describes design principles and key design criteria when installing fishways on irrigation facilities as well as common mistakes in design. In addition, the Guideline describes the processes and key considerations on construction, operation, maintenance, and adjustment of fishway.
The Fishway Monitoring Manual focuses on assessing fish migration with method of fishway monitoring as a complementary document of the Fishway Guidelines for Irrigation Facilities. The Manual is intended to be used for practitioners on-site with the Fishway Guidelines.
