Using the lens of the baobab tree, this paper explores the ecological outcomes of different tenurial arrangements and implications for resource sustainability. With the emergence of markets for baobab products, a central concern is to confirm whether use patterns differ across different tenure regimes and, if so, their ecological outcomes. The study is based on an ecological survey in Zimbabwe of 244 baobab trees located across three tenure regimes – communal, private and state – and also draws on interviews with key informants. The results suggest that tenure has a strong influence on the sustainability of baobab harvesting. Based on identified parameters of ecological sustainability, trees under state tenure were shown to be harvested unsustainably, and showed excessive bark harvesting, while those under private and communal tenure had fewer signs of debarking and produced more fruits, suggesting their use was more sustainable. Excessive bark harvesting was found to negatively affect fruit and bark production and, to a lesser extent, the overall health of the tree. The research illustrates that in order to understand ecologically sustainable use, an understanding of resource use patterns across different tenure regimes is crucial, suggesting the design of bespoke interventions to manage the use of natural resources in different tenure systems.

Environmental research is often conducted independently of the community in which the environment is situated, with transfer of results into policy and on-ground action occurring independently of the community's interests or aspirations. Increasingly the need for greater community involvement in the research process has been recognized. For community members, however, such engagement usually involves trade-offs. While it is often assumed that community members should participate voluntarily because they will gain from the research, any benefits from knowledge, understanding and a capacity to influence the research have to be offset against time and potential loss of unremunerated intellectual property. We argue, using case studies from tropical Australia and Africa, that a more effective means of engagement and knowledge transfer is training and remuneration of community members as coresearchers. This engagement is much more than payment for labor—it is investment in local intellectual property and requires researcher humility, power-sharing and recognition that access to research funding provides no moral or intellectual authority. Further, we argue that, for effective adoption of research results, community members need to be part of negotiated agreements on the initial nature of the research to ensure it answers questions of genuine local relevance and that local researchers have the capacity to place locally conducted research into a wider context. We argue that immediate rewards for involvement not only secure engagement but, where appropriate, are likely to lead to effective implementation of research results, enhanced local capacity and greater equity in intellectual power-sharing.
