Bowal (plural bowé) is a particular form of degraded land on hardened ferruginous soils (ferricrete) found in tropical regions with unimodal precipitation. It is characterized by ferricrete exposure due to soil surface erosion. The drivers of bowé establishment in Benin are mainly deforestation. Bowalization leads to loss of biodiversity and changes in vegetation structure. The vegetation on bowé is characterized by annual herbaceous plants and trees with impeded roots growth and structural adaptions. Bowalization is predicted to persist and increase in extent in the future.
The present project aims to promote best practice for combating bowalization and adoption of conservation strategies of biodiversity using the native species adapted on bowé and resistant to climate change for ecological restoration of bowé. These species are Asparagus africanus, Andropogon pseudapricus and Combretum nigricans in the semiarid climate zone in Benin, and Asparagus africanus, Detarium microcarpum and Lannea microcarpa in the sub-humid climate zone in Benin.
The results of the observation and farmers’ field school will be presented during training workshops and meetings towards farmers and local institution. Exchange experiences with the farmers and local institution will allow building the framework of observed restoration strategies of bowé. This will help participants to jointly develop priorities for management, conservation and future research. Outputs of the workshop will allow us to develop and implement several sensitizations on best practices for restoration strategies of bowé. Moreover we will do a lobbying based on our results to facilitate the inclusion of certain indigenous soil restoration practices in laws, decision making on soil conservation strategies and policies in Benin.
