Résumé
Mountain drylands face alarming desertification risks. Restoring and diversifying the woodlands in agro-ecosystems (agroforestry) is crucial for enhancing these regions’ socio-ecological resilience. By using a biocultural theoretical perspective, this doctoral thesis analyzes the potential of native woody species from the Bolivian Andes for use in agroforestry by calculating their socio-ecological values and by experimentally testing different methods that could facilitate their propagation under drought conditions. Timber trees are shown to be highly valued by local people. The results also indicate a potential decline of the values attributed to native woody plants. This is likely to be brought about by their decreasing availability due to woodland destructions, to their substitution by commercially profitable exotic trees, and to the loss of traditional plant uses and knowledge, which is accelerated by rural out-migration. This thesis argues that understanding local human-plant relationships and their dynamics is a crucial prerequisite to any practical initiative for the restoration of woodlands in agro-ecosystems.
