In August of 2008, the Mekong School held its first reunion, bringing together twenty-seven participants from three generations of students at Si Phan Don, Southern Lao PDR. ERI Asia Director Chana Maung, Jessica Rosien of Oxfam Australia , and Mekong school staff and volunteers also joined the group. The Si Phan Don area is the site of the controversial Don Sahong Dam, where Lao and Cambodian alumni are working to mitigate adverse impacts on riverside communities.

During the five-night, four-day reunion, three generations of Mekong School students shared their challenges and accomplishments following graduation and renewed their motivation for working for human rights and environmental justice. Alumni met in country groups to prioritize earth rights challenges currently facing their communities, and reported back to the larger group. Based on these reports, the facilitator developed a list of critical issues shared by communities throughout the region, and alumni then broke into topic groups to strategize and plan joint campaigns.
