The Mekong
Shapes Everything

In the lower Mekong Basin, students investigate how freshwater ecosystems, forests, and communities are connected, and how they're changing.

Where the River Runs Backward

The Tonle Sap is a lake that breathes. Each monsoon it reverses flow, swelling to five times its dry-season size and flooding forests that sustain one of the most productive inland fisheries on Earth. The SFS Center for Environmental Justice and Mekong Ecologies sits on the outskirts of Siem Reap, minutes from the Angkor ruins, in a river basin that holds over 1,200 fish species, Irrawaddy dolphins, and giant freshwater stingrays, 19% of them threatened.

Semester excursions reach the Elephant Valley Project in Mondulkiri, where Keo Seima Wildlife Sanctuary protects over 60 globally threatened species, and floating villages on the Tonle Sap where students overnight in homes that rise and fall with the water. They observe elephant foraging behavior in evergreen forest, survey bat populations at Siem Reap's Botanical Gardens, and conduct fish morphology exercises alongside Cambodian university students in communities where livelihoods depend on every catch.

Freshwater Ecology & Environmental Justice

Research spans watersnake bycatch and trade on the Tonle Sap, elephant welfare and cognition at the Elephant Valley Project, camera trap surveys of wildlife reintroduction impacts, and land cover change in Bunong indigenous communities, contributing data to conservation partners protecting one of the world's most threatened freshwater systems.

Hands-On Field Methods

  • Primate Behavior Observation

    Observe wild, habituated primates at Jahoo and study the social dynamics between troops
  • Freshwater Ecology Sampling

    Measure water quality, fish diversity, and flow dynamics across Tonle Sap floodplain sites
  • Camera Trapping

    Deploy and manage camera trap arrays in evergreen forest to monitor large mammals
  • Community Livelihood Surveys

    Interview fishing and farming households on climate adaptation and resource governance
  • GPS Habitat Mapping

    Record land-cover boundaries and habitat features for spatial analysis in GIS
  • Forest Structure Assessment

    Quantify canopy height, stem density, and regeneration in community and protected forests
  • Fish Catch Monitoring

    Record species, size, and abundance from local fishing catches to assess stock health
  • Macroinvertebrate Surveys

    Sample and identify aquatic macroinvertebrates as bioindicators across Tonle Sap floodplain sites

Watersnake Bycatch and Trade, Kampong Khleang

Counted catch and interviewed the fishers and traders of Kampong Khleang, extending a multi-year record that can separate a natural dip in the endemic Tonle Sap watersnake from a true decline.

Participatory Land Use Research with Indigenous Researchers

Worked with Indigenous researchers from across Cambodia on land use research designed so the communities whose land is at stake set the questions rather than answer someone else's.

Food for Thought: The Household-Level Decision-Making for the Adoption of the Participatory Guarantee System. A Case Study at ECOFARM and FUDAC in Siem Reap, Cambodia

The Participatory Guarantee System lets farmers certify each other rather than pay an outside inspector. A serious game, a first for the center, drew out how households decide to join.

Romp or Restless: A Behavioral Comparison Between Otter Pairs and Families in Captivity

Compared otters kept in pairs against those in family groups, testing whether social grouping changes activity and welfare. The answer shapes how rescue centers house their animals.

Community & Culture

The center sits on the outskirts of Siem Reap, with five rooms of two to four students, air conditioning, en-suite bathrooms, and a pool on campus. Students travel extensively: from Prek Toal and Kampong Khleang on the Tonle Sap to the Bunong communities of Mondulkiri, a world apart from the temples of Angkor.

Students spend a night in a floating village at Prek Toal on the Tonle Sap, speaking with families about livelihood change. They travel to the Elephant Valley Project in Mondulkiri to work alongside Bunong mahouts, tour Angkor Wat with a professional guide, attend the Phare Cambodian Circus, interview elders in Kratie and Stung Treng, and visit Tuol Sleng for genocide remembrance. A Khmer language course roots all fieldwork in local context.
