Development Challenge:

Artisanal and small-scale mining produces one out of every four diamonds in the world. As the industry rapidly expands, there is increasing global attention on the societal and environmental impacts of mining, the difficult working conditions miners face, and the linkage between diamond mining and armed conflict.



Since 2007, Tetra Tech has worked in four countries—Central African Republic (CAR), Liberia, Guinea, and Cote d’Ivoire—to implement the Property Rights and Artisanal Diamond Development Project (PRADD and PRADD II), the world’s largest development project in support of artisanal diamond miners. Funded by the U.S. Agency for International Development (USAID) and the European Union, the project works to formalize miners’ rights to land and property in order to improve artisanal miners’ livelihoods and increase the volume of diamonds that are legally exported.  

By documenting and securing miners’ land and property rights, it enables miners to work more effectively with investors, allow governments to track production, and reduce diamond-related conflicts. The project uses an innovative approach—the establishment of village-based equipment rental pools—to increase production, and profit, for artisanal miners. Training in diamond valuation and improved prospection and extraction techniques helps to increase profits for hundreds of miners in target communities.

The project successfully formalized and documented the property rights of 3,000 miners in CAR and 500 miners in Liberia over a 2-year period, improving the economic security of this often marginalized group.
•    In CAR’s provinces, the volume of legally-sold diamonds increased by 800% in three years.
•    In Liberia, the percentage of legal sales in project areas increased by 20%.
•    Worked with miners to convert 654 exhausted pits into fish ponds.
•    In CAR, the number of legally registered miners doubled in two years.
•    The project produced an assessment tool that is now used by the Kimberley Process to measure good policy.
Through its combination of property rights, governance, value chain enhancement, and environmental rehabilitation, PRADD became a flagship program to curb the flow of conflict diamonds into the marketplace, and boost national economies in target countries.
