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.
This Data Acquisition and Generation Action Plan (DAGAP) has been developed to provide a clearer direction to the Member Countries and the MRC Secretariat on the data requirements necessary to implement the Mekong River Basin Indicator Framework (MRB-IF). It details the mechanisms that need to be put in place and systematically implemented to acquire and/or generate data to ensure the next State of the Basin Report will not have the same data gaps of previous reports.
This reports on the results of the monitoring of water quality across 48 stations in the LMB. The report shows the water quality in the Mekong and Bassac Rivers was still of good quality with the slight improvement compared with 2016. There was only a small number of measurements of chemical oxygen demand (COD) and dissolved oxygen (DO) that violated the MRC Water Quality Guidelines for the Protection of Human Health (WQGH) and the MRC Water Quality Guidelines for the Protection of Aquatic Life (WQGA). Most exceedances were recorded in the Delta. Of a slight concern was the DO level at Chau Doc, which violated the WQGH for all sampling occasions causing water quality for the protection of human health to be downgraded from ‘good’ in 2017 to ‘moderate’ in 2018.
The MRC Writing, Publication and Style Guide contains guidance on common problems of English grammar, spelling, hyphenation, capitalization, document referencing, in-text citations, and bibliography organization. First published in 2007, this second edition of the Guide is intended for creators of MRC’s documents and publications, including MRC Secretariat’s staff members and consultants as well as external users who need a style guide.
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.
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.
This handbook provides guidance on the principles and practice of stakeholder engagement within the MRC’s cooperation context. It spells out the different types of stakeholders, the engagement mechanisms and channels, and the related access and dissemination of information. It aims to contribute to increasing the understanding of the MRC’s principles and approaches in working with diverse stakeholders who have interests and concerns over the development and management of the Mekong River System.
Achievements the Completion Report 2016–2020 presents the MRC’s key
Achievements in terms of the completion of outputs, the achievements of outcomes and financial performance during the five-year implementation of the MRC Strategic Plan 2016–2020 and its Annual Work Plans. It also includes the lessons learned from that period, and how they formed the basis of the next planning cycle – the Basin Development Strategy 2021–2030 and the MRC Strategic Plan 2021–2025.
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.
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.
