CORRESPONDANCES ENTRE SAVOIRS LOCAUX ET SCIENTIFIQUES : PERCEPTIONS DES CHANGEMENTS CLIMATIQUES ET ADAPTATIONS ETUDE EN REGION COTONNIERE DU NORD DU BENIN

Résumé

A survey carried out in four regions of Benin with different climatic profiles have shown producers' perceptions on climatic changes, their consequences and the different adapted measures taken by producers in order to deal with such consequences. Methodologies used comprise group discussions as well as individual interviews with open-ended, semi open and open questionnaires. The present paper is based on research results from 110 family farms of two villages in the northern region. Climate is Sudanese and the production system is cotton based. Recent climate trends perceived by producers are: irregular rainfalls, shortening of cultivation season, occurrence of violent winds and a increase of temperatures. Conventional analyses of climate series highlight significant increases of maxima and minima temperatures, although fail to show significant increases in violent winds as well as significant differences in rainfall distributions. Adaptive measures put to use by producers are many, but scarcely compensate negative effects of climate changes. Farms with little production means remain vulnerable. The study of producers' perceptions of climate changes traduces the need for a new approach in the analysis of climatic variables based on micro spatial and temporal scales.
