This ex-post impact assessment will document the durable environmental and household livelihood benefits of research on the institutional management of forests under the LAMIL project in Guinea eight years after the cessation of project activities. Specifically, the durability, spread, and impact of innovations generated between 2005 and 2008 in project treated forest reserves and adjacent villages will be estimated through a unique two-level analysis of environmental and household livelihood benefit. Environmental benefits are established through the estimation of differential changes in major land use categories in the four project treated forest reserves and four control forest reserves with no project interventions using remote sensing data on land use cover before, during, and after project implementation. A household survey also will be conducted in 8 villages adjacent to the project forest reserves and 8 villages adjacent to control forest reserves to document the durability of project innovations within treated forest reserves and adjacent villages, as well as the spread of project innovations to control forest reserves and their adjacent villages. Household livelihood impacts will be inferred through the estimation of differences in forest, agroforestry, and agricultural benefit flows associated with specific project innovations in adopting households and otherwise similar non-adopting households.
