Strategies to promote sustainable development: The gendered importance of addressing diminishing African Locust Bean (Parkia biglobosa) resources in northern Ghana’s agro-ecological landscape

Abstract

As the topic of gender and forests gains international attention through programs related to addressing the Sustainable Development Goals, we focus on a case study of the African Locust Bean (Parkia biglobosa) in the savannah landscape of northern Ghana. Although this tree holds high cultural significance for Dagomba women, it is unfortunately becoming scarcer in our study area near Tamale. We investigate the reasons for this decline in relation to the agricultural, ecological, and cultural landscape and discuss the gendered impacts of these changes. Research in these communities was conducted between 2018 and 2021 as part of a transdisciplinary action research approach to process underutilized species with women’s groups. The research started with a survey that included 27 women’s groups in 13 communities with 524 women participants. Out of a selected number of groups, our research team has worked more intensively with three women’s groups near Nyankpala, which selected for their processing focus the African Locust Bean, locally known as dawadawa. More than 45 group sessions were organized with seven groups in a collaborative learning process in 2019. Additionally, the three groups in Kpachi who chose to process the African Locust Bean sustained facilitation of group activities until the end of 2021. Specifically, on the topic of the decline of this tree, 19 semistructured interviews were conducted in August 2020 with 8 female farmers, 7 male farmers and 4 chiefs in the local governance system. Our results show the cultural significance of the African Locust Bean for women in the Dagomba culture as well as practical uses of all parts of the tree. Specifically, the seeds are used for making a fermented condiment and tea. Although seeds of the African Locust Bean are considered a women’s crop, their access to this tree is mediated by the local chiefs and often male land-users. Most farmers interviewed reported a reduction in trees in their fields. The reasons for the decrease can be summarized in six different categories, (1) aging tree populations, (2) challenge caring for saplings until maturity, (3) agricultural changes with increased mechanization and pesticide use, (4) over-use as a firewood resource, (5) usufruct rights between traditional chiefs, male land-owners, and women who should be granted access to the trees according to Dagomba cultural values, and (6) reduced water availability inhibits seed yield. In conclusion, there is an urgent need for action to protect and restore the African Locust Bean within northern Ghana’s savannah landscape to ensure continued access and benefits of the tree to women in the region.
