“…An MSRPS results from the slashing of the mangrove trees and the construction of dikes for the creation of paddies [5]. Thus, MSRPSs have been pointed out as the main cause of mangrove deforestation in Guinea Bissau [6,7]. Among the West African countries practicing mangrove swamp rice cultivation, Guinea Bissau has the largest area occupied by this farming system [7][8][9] and the highest total production.…”

The mangrove swamp rice production system (MSRPS) in West Africa faces significant challenges in soil, water, and salinity management, making rice production highly vulnerable to variations in the spatio-temporal distribution patterns of rainfall, which are exacerbated by climate change. This study’s results can provide the initial basis for co-developing strategies with farmers aiming to contribute to the biophysical characterization of the MSRPS, in particular: (i) estimate the water-harvesting efficiency (WLef) of the plots in the north and south of Guinea Bissau (GB); (ii) characterize the unevenness of the bottom of the plots, which leads to salinization spots; and (iii) create soil consistency maps to provide farmers with a tool to prioritize sites with optimal conditions for tillage. The research was conducted between 2021 and 2023 in the study site of Cafine-Cafal in the south and Elalab in the north of GB. Systematic soil sampling in a grid was designed to quantify the soil consistency and plot/ridge areas were determined. Linear models were developed to predict biophysical parameters (e.g., effective planting areas and water-logging depths) and geostatistics were used to create soil consistency maps for each study site. The results show precipitation water-harvesting efficiencies of 15% and 16% for the southern and northern regions, respectively. Furthermore, the plasticity limits of 18.6% for Elalab and 35.5% for Cafine-Cafal show the most appropriate times to start tillage in specific areas of the paddies. This study provides information on the efficient management of tillage and freshwater conservation, providing MSRPS farmers with useful tools to counteract the effects caused by salinity and rainfall variability.

Biodiversity loss, habitat degradation, globalization, and societal transformations are challenging rural, and especially coastal communities in Guinea-Bissau where mangrove-dependent livelihoods are exposed to increased vulnerability. The Diola, traditional farmer-fishermen of the northern island-villages, have witnessed swift societal changes following the country’s economic liberalization, climate change, and youth migration from rural areas. Despite historically being a secondary subsistence activity with more predefined gender roles rooted in tradition, mangrove fishing has become a major source of cash income. Yet, women’s mangrove fishing contributions are still overlooked, resulting in general assumptions of static female fishing identities with limited control over their income. We present three case studies of Diola women’s involvement in mangrove fishing through a mixed method approach that combines qualitative techniques and household surveys conducted between 2017 and 2023. Specifically, we explore: (1) diverging societal coping strategies and livelihood developments in three Diola villages; (2) the primary drivers behind village-specific societal transformations; (3) social dynamics and female roles in mangrove fishing-related activities and village decision-making; and (4) the political ecology of interventions. Our findings underscore the complexity of gender-fluid small-scale fishing strategies as female roles beyond fish trade defy cultural generalizations. Contemporary Diola women make autonomous personal and work choices that meet their current needs and add to their household budget to face new welfare demands. Inclusive resource governance needs more gender-specific data for meaningfully implemented interventions adapted to local circumstances, enabling an active participation of all genders in conservation practices and development.
