This study focuses on the impact of the security crisis and flooding on bell pepper production in the Commune Urbaine de Diffa. The effects of the security crisis are a real tragedy for the population in general and producers in particular. The damage caused to the region's economy is considerable. The overall aim of the study is to show the impact of the security crisis and flooding on bell pepper production in the Commune Urbaine de Diffa. The results obtained show that the security crisis and recurrent flooding have had a negative impact on the bell pepper industry in the urban commune of Diffa. Firstly, 45% of producers surveyed had stopped bell pepper production because of Boko Haram insecurity, and 32% had abandoned their production land because of recurrent flooding. The reduction in the area under cultivation and the fall in production were the most significant impacts, resulting respectively in a reduction of almost 78.4 hectares, or 73.17% of the area under production, and a fall in production of around 85.11%.
