Impact des feux de brousse sur la biodiversité et la sécurité alimentaire : évaluation des effets écologiques, agronomiques et socio-économiques

Bushfires constitute a recurrent phenomenon in many sahelian and savannah regions, profoundly influencing ecosystems and human livelihoods. This study examines the ecological impacts of bushfires on biodiversity (flora and fauna) and their implications for the food security of local populations. By integrating ecological, agronomic, and socio-economic approaches, we assess how burning practices affect species composition, soil productivity, agricultural yields, and community adaptation strategies. The results indicate a significant biodiversity loss of 28%, a reduction in ecosystem resilience of up to 35% one year after seasonal fires, and adverse effects on agricultural production, with an average yield decline of 22% in plots located near burned areas, thereby directly threatening food security. The findings further suggest that integrated fire management practices and ecological restoration programs can mitigate these impacts.
