Across northeastern Cambodia, Tetra Tech is conserving biodiversity, combatting deforestation, improving governance, and promoting sustainable economic growth.

The Prey Lang Extended Landscape covers more than 3.3 million hectares of forest, watersheds, and agricultural land in northeastern Cambodia. It is home to more than 1 million people, numerous protected areas; United Nations Educational, Scientific and Cultural Organization (UNESCO) world heritage sites; and dozens of endangered animal and plant species. The vast diversity and beauty of this landscape is under severe threat from deforestation, illegal logging, wildlife trafficking, and the impacts of climate change.

To address these challenges, Tetra Tech is leading the implementation of the U.S. Government’s flagship Cambodian environmental project, United States Agency for International Development Greening Prey Lang (USAID GPL). Through three offices and with the support of more than 120 staff, Tetra Tech and its partners, Wildlife Conservation Society and Conservation International, are leading an integrated approach to promote conservation-friendly, resilient, and low-emission sustainable economic development.

This approach addresses the direct and indirect links between ecosystem health, economic opportunity, and inclusive access to opportunities, decision-making, and sustainable development. Through USAID GPL, Tetra Tech is improving participation and evidence-based decision making in Cambodia’s management of its forests and biodiversity to lower greenhouse gas emissions, create economic opportunities for rural people, and mobilize investment in forest carbon, ecotourism, and sustainable agriculture.

Since late 2018 USAID GPL has:

  • Developed and disseminated a climate change vulnerability and biodiversity threats assessment
  • Supported the establishment of 45 community protected areas and strengthened their functionality
  • Developed a joint patrol to promote participation in law enforcement planning and patrols
  • Trained more than 300 rangers, community members, and local communities to use new technologies
  • Improved economic and livelihood co-benefits for close to 60,000 people
  • Avoided the emission of 2 million tons of carbon dioxide
  • Improved biophysical conditions on more than 1 million hectares of protected areas
