A Floating Village. A Floodplain. A Semester.
A fishing family's house floats on the Tonle Sap, rising with the monsoon, sinking with the dry season, and moving when the lake does. Over 300 fish species swim beneath them. Irrawaddy dolphins move through the same water. Across the Mekong basin, nearly one in five fish species is threatened, and the communities who depend on every catch are watching the river change. This semester traces those connections: freshwater ecology, forest conservation, and environmental justice across the Lower Mekong.
Students measure fish morphology at Prek Toal, survey macroinvertebrates as the water rises, and spend nights in floating villages interviewing fishing families about livelihood change. Excursions to the Elephant Valley Project in Mondulkiri bring students alongside Bunong mahouts and Asian elephants in evergreen forest, deep in Cambodia's eastern highlands, a world away from the temples of Angkor that frame their home base in Siem Reap.
What You'll Do
Tonle Sap Fisheries Research
Measure fish morphology at Prek Toal, collect water quality samples, and survey aquatic macroinvertebrates as bioindicators across the flood-pulse lake.
Village Homestay
Spend one night camping on Kulen Mountain and another at the Prek Toal floating village, interviewing ecotourism workers and fishing families about changing livelihoods and surveying birdlife across the Tonle Sap.
Elephant Ecology at EVP
Observe foraging behavior and assess elephant welfare, social behavior, and their role as ecosystem engineers at the Elephant Valley Project in Mondulkiri.
Bunong Indigenous Communities
Visit Bousra, Loav Ka, and Putrom to study indigenous land tenure, communal title, and natural resource access in Mondulkiri's Bunong communities.
Khmer Language & Culture
Study conversational Khmer, tour the Angkor Archaeological Park with a professional guide, attend the Phare Cambodian Circus, and share traditional food during a theater performance. Interview elders in Kratie and Stung Treng, and visit Tuol Sleng for genocide remembrance.
GIS & Drone Mapping
Learn QGIS, collect GPS waypoints, and fly drones over indigenous farmland in Kratie to produce aerial land-use maps for environmental governance research.
Field Sites
From flood-pulse lake to Mondulkiri evergreen forest: fieldwork spanning the Mekong Basin's most threatened ecosystems.
Tonle Sap Lake
Overnight homestays, fish surveys, and bird monitoring at Prek Toal, on Southeast Asia's largest lake.
Elephant Valley Project
Extended fieldwork in Mondulkiri on elephant ecology and welfare, alongside the Bunong community.
Angkor & Siem Reap
Your home base for the semester: Angkor Wat, bat censuses in the botanical garden, and GIS drone mapping.
Where Water, Food, and Justice Are the Same Question
Proposed hydroelectric dams could reshape the Mekong's flood pulse, the seasonal engine that drives fisheries productivity for sixty million people. Across the basin, 19% of fish species are globally threatened. Students trace those connections from floodplain research sites: water quality testing, fish niche and morphology exercises, macroinvertebrate bioindicator surveys, and dam development debates grounded in the hydrology they've measured firsthand.
Interdisciplinary & Field-Based
Five courses weave freshwater ecology, conservation science, and environmental ethics into a field-driven curriculum. Students count bats at the Siem Reap Botanical Gardens, measure fish morphology at Prek Toal, fly drones for GIS land-use mapping, and study Bunong land tenure in Mondulkiri, all building toward Directed Research that addresses real stakeholder questions in biodiversity, governance, or livelihood transformation.
Courses
Five integrated courses totaling 18 credits
Studies the Tonle Sap flood-pulse ecosystem through water quality testing, fish morphology analysis at Prek Toal, macroinvertebrate bioindicator surveys, and aquaculture field visits.
