Tetra Tech, Inc. (NASDAQ: TTEK) announced today that the U.S. Agency for International Development (USAID) has awarded the Company a $49 million single-award contract to promote climate-resilient communities and protect biodiversity in West Africa.

West African countries are particularly vulnerable to the effects of urbanization, overfishing, and increased risk of floods in coastal areas. The region’s inland forests are also threatened by conversion to agricultural use and unsustainable land-use practices.

Under the five-year West Africa Biodiversity and Climate Change project, Tetra Tech will collect and disseminate critical data sets, increase the capacity of resource agencies to interpret data for more informed decision making, and develop sustainable best practices that can be shared across the region.

Tetra Tech will work with partners at the regional, national, and community levels to strengthen policies that will improve natural resource management and the health of marine ecosystems in West Africa. “Tetra Tech is pleased to continue supporting USAID in providing innovative solutions to address the impacts of climate change around the world,” said Dan Batrack, Tetra Tech’s Chairman and CEO.
