This document summarizes research on changing access to shea trees in Burkina Faso. Migration and population growth have increased competition for land and shea nuts. The globalization of the shea trade has also commoditized shea and increased exports. As a result, there is now uncertainty around the social rules of access to shea trees and contested claims over ownership between original inhabitants and later migrants. Access to shea trees on cultivated land or in shorter fallows is becoming increasingly restricted to individual farm households rather than available to all community members. Conflicts over shea tree access are also tied to underlying disputes over land tenure and struggles for control of resources.
