Tetra Tech Inc. has been awarded a $22 million contract from the U.S. Agency For International Development to support biodiversity protection and community development efforts in Madagascar.

Under the five-year contract, the Pasadena engineering and consulting firm will support biodiversity conservation efforts in forested and coastal areas of the island nation off the east coast of southern Africa. The contract also calls for the company to help communities on the island manage their natural resources, especially water infrastructure.

“Tetra Tech is pleased to support USAID’s work in Madagascar to conserve the island’s world-renowned biodiversity, while improving the lives of its citizens,” Dan Batrack, Tetra Tech chairman and chief executive, said in a statement.
