Tetra Tech works with societies to sustainably strengthen weakened social, economic, and governance systems.

Our approach is based on the fundamental premises that security and stability are a public good and service. We believe that security is necessary to combat poverty, promote effective development, and help install a sense of resiliency toward crime, violence, conflict, and extremism.

Partner countries are typically emerging from violent conflict; are otherwise at risk of becoming fragile or unstable states; or are considered high-priority countries in respect to countering terrorism, extremism, trafficking, and other forms of transnational crime. Our teams work in ungoverned, under-governed, and poorly governed environments to help promote policy development and implementation; assist with effective institutional strengthening, reform, and capacity building; and support development of partnerships among public institutions, private sector organizations, and community stakeholders.

Counterterrorism and Counter Violent Extremism

Development and foreign assistance are increasingly integrated into government responses to complex national security challenges, including those associated with promoting sustainable development in the face of conflict, instability, and state failure. Consequently, government and interagency orientations expand to include partnerships with a range of U.S. and international non-governmental actors. Tetra Tech has worked closely with the U.S. Agency for International Development (USAID) and the U.S. Departments of State and Defense to help prevent, mitigate, and transform violent conflict and instability. We are helping to close the socio-economic and political gaps that permit or facilitate the growth of terrorist and violent extremist ideology and behavior, while promoting community and state resiliency.

Counter Narcotics, Trafficking, and Gangs

Tetra Tech supports specialized efforts that are vital to sustainable development, security, and stability—combating transnational crime and corruption, and counter narcoterrorism. Trafficking drugs, persons, weapons, and illegitimate finances cause significant consequences for families, communities, businesses, and governments. These issues cause economic “de-value” chains, psychological and physical effects of violence and violent conflict, and weakened governance systems. Tetra Tech has long supported numerous U.S. Department of State and USAID bureaus and offices, and other U.S. government agencies, to prevent, counter, and arrest such illegality.
