Abstract
The Likouala-aux-Herbes river and surrounding swamp forests of the northern Republic of Congo are described in scientific literature as a wetland forest system characterized by a bimodal flood pulse and widespread seasonal flooding. Recent climatic and hydrological modelling of the Congo Basin and Cuvette Centrale peatlands, moreover, positions the Likouala region as a rain-fed or ombrotrophic peatland. However, human populations experience and adapt to flooding at a more localized scale. This study presents ethnographic data on flooding and seasonality from six villages within the Lac Télé Community Reserve (LTCR), a protected area in the Likouala swamp forest biome and the country’s only Community Reserve. Our findings reveal how spatio-temporally variable flooding produces village-specific cultures, livelihood cycles, adaptations and vulnerabilities—an interconnected gradient of biocultural relationships. Across villages, flood dynamics have changed drastically over the last decades. Climate change, economic transitions and erosion of local knowledge systems are straining long-standing adaptive frameworks within and between LTCR communities. We emphasize the importance of ethnographic data in understanding fine-scale human–environment interactions and suggest that biocultural analysis at this scale—what we term the ‘hydrocultural patch’—is essential for effective landscape governance and policy development in the context of accelerating climate change.
