Mekong River

The Mekong River Basin


The Mekong River is approximately 4,350 km long, and is the 12th longest river in the world and the 7th longest river in Asia. The Mekong River Basin drains 795,000 km2. Originating in the Tibetan Plateau, the Mekong River crosses southern China before passing Myanmar, Laos, Thailand, Cambodia and Vietnam, where the Mekong flows into the South China Sea.


The Mekong River Basin is home to a large variety of ethnic groups. Millions of people are heavily dependent on Mekong Basin fisheries for food and income. No wonder the Mekong River Basin supports the most important fresh-water fisheries in the world, with an estimated annual fish production in the basin of between 2.3 and 3 million tonnes annually. The freshwater environments of the Mekong River Basin support well over 500 species of fish, making the Mekong one of the most biodiverse rivers in the world.

Tracking Changes… in the Mekong River Basin


The Tracking Changes Project funded by SSHRC is working primarily with ethnic Lao people living in northeastern Thailand (particularly Ubon Ratchathani Province), southern Laos (particularly Champasak Province) and northeastern Cambodia (particularly Stung Treng Province) to investigate wild fish, fish migrations, and associated capture fisheries.


The work in the Mekong River Basin is being primarily coordinated by Dr. Ian Baird from the Department of Geography, University of Wisconsin-Madison, Madison, Wisconsin, USA ( and Dr. Kanokwan Manorom from the Faculty of Liberal Arts, Ubon Ratchathani University, Ubon Ratchathani, Thailand. A number of graduate students are expected to work on the project.


The research in the Mekong River Basin is initially focusing on collaborative research involving local people and local researchers in order to investigation how intimate knowledge about fish and fish migrations is disseminated through social networks that extend over space, including crossing national borders. We are also studying the dissemination of fish related knowledge between people, and across generations.

Knowing the River: Utilizing Traditional Knowledge to Shape New Discourses in the Age of Dams

The Mekong River and its tributaries has long been a source of vitality for those living along banks.  It has also served as a conduit for material and intellectual exchange throughout history.  Today, the river draws interest from both ecologists and developers due to its biodiversity and energy potential.  As the Mekong Subregion undergoes greater transformation, there is a need to understand how such transformations impact local stakeholders.  My research explores the pedagogical history of Lao communities in northeastern Thailand, southern Laos, and northeastern Cambodia in light of environmental change and major development projects.  I am interested in how technology, international borders, and ideas of indigeneity, identity, and landscape have complicated or facilitated discourses of acceptance, acquiescence, and resistance in and among these communities.

Gender and Indigenous Knowledge on Fisheries in the Mun River and Si Phan Don in Southern Laos

The study focuses on gender and fishery knowledge along the Mun River, wetland areas, and Si Phan Don (Four Thousand Islands) in southern Laos. Many scholars have addressed that fishing activities in the areas are very crucial for local livelihoods. Males and females have different knowledge on fishing, depending on their roles ecological systems, development activities and policies of water resource management.

Fishery Resources and Knowledge Management Through Empowerment of Local Wisdom in the Mun and Mekong Rivers

From the Mekong source to its delta, the river travels 4,909km. Along the Mekong, local communities utilize the river in different ways; it is a source of life, providing food, transportation, and security of life. There are over 60 million people who directly depend on its rich natural resources. The lower basin is the most productive fresh-water fishery in the world. Along the Thai-Lao-Cambodia border, complex ecosystems, including those centered on rapids, whirlpools, beaches, and tributaries, are the important fishing grounds for local communities. This research focuses on fishery resources and knowledge management, and how to empower local wisdom. Research sites cover the Pak Mun Dam in Thailand, Donsahong Dam in Southern Laos, and Tonlesap areas in Cambodia.

Local Fishers Knowledge in Governance in the Lower Mekong and Fraser Basins

The goal of this proposed project to learn more about the role of Traditional Ecological Knowledge (TEK) and management practices in decision-making about the sustainability of fish and fishing livelihoods in the Lower Mekong and Fraser Basins. The two specific objectives are to determine: a) what and how TEK is being systematically generated about culturally valued fish species that are currently ‘endangered’ (e.g., Giant Catfish Panasianodon gigas ‘pla buek’), and b) how this knowledge is influencing governance of fish and fishing livelihoods at different scales. Oloriz hopes to learn from local fishers, leaders and government representatives about different aspects of Traditional Knowledge and its potential role in governance. Most importantly, she would like to contribute to the sustainability of local ecosystems, fishing practices and livelihoods.

Diversification of Livelihoods in a Region Impacted by Hydroelectric Development: A Case Study in the Lower Mekong (Mun River/Sebok River)

Local people living along The Mun River and its tributaries, such as the Sebok River, hold a deep connection to the fresh water ecosystem and have longstanding traditional practices that are critical to their fishing livelihoods. These traditions and practices have been passed down over many generations and are based on well-developed local knowledge of their environment and communities. However due to the rapid development of hydropower in the Mekong Basin, fishing livelihoods are becoming increasingly complicated by environmental impacts to aquatic ecosystems. Many households and communities are thus diversifying their livelihoods to survive. This thesis explores how local villagers in fishing communities on the Mun River and its tributary, the Sebok River, in Thailand, diversify their livelihoods and show resilience to the effects of hydroelectric development. Semi-structured interviews were conducted in nine villages to collect themes and opinions on the operation of the Pak Mun Dam, a controversial dam located near the confluence of the Mekong and Mun Rivers, and its effects on communities over the past twenty-five years. Emerging themes from the interviews showcase the importance of fish and fishing livelihood, culture, diversifications, community and connection to land. These themes relate to existing theory and demonstrate the importance of Traditional Knowledge, resilience and well-being. The information presented in this thesis also showcases how Traditional Ecological Knowledge (TEK) can be utilized towards community-based resource management and community involvement in decision-making regarding hydroelectric development.
