Connaissances endogènes et perceptions paysannes de l’impact des changements climatiques sur la production et la diversité du niébé (<i>Vigna unguiculata</i> (L.)Walp.) et du voandzou (<i>Vigna subterranea</i> (L) Verdc.) au Bénin

Abstract: REMERCIEMENTSNous exprimons notre profonde reconnaissance à l'Etat béninois pour la bourse de thèse qui nous a été accordée. RESUME L'existence d'impacts néfastes du changement climatique sur la production agricole en Afrique subsaharienne est maintenant solidement établie. Pour documenter les connaissances endogènes relatives au changement climatique, identifier les contraintes qui y sont associées et qui affectent la production et la diversité du niébé et du voandzou au Bénin et examiner les stratégies adapt… Show more

“…Our results show that insect attack remains the most important constraint related to the storage of Kersting's groundnut seeds in central and southern Benin, which corroborates previous observations by Assogba et al (2015). Generally, insect attack remains the main constraint of many stored seed legumes in the tropics (Gbaguidi et al, 2015;Worou et al, 2016), with losses up to 70% (Guèye, Seck, Wathelet, & Lognay, 2011;Ngamo & Hance, 2007). Among the control approaches proposed by farmers, the promotion of Kersting's groundnut varieties resistant to insect pests was the most important.…”

“…Nous signalerons quand même que Guo and Qin, 2010, au cours d'études effectuées en Chine, n'ont obtenu aucune corrélation entre la température et l'importance des populations de P. xylostella. Ces résultats témoignent de l'importance de la fluctuation de la température due aux changements climatiques au niveau mondial ces dernières années (Loko et al, 2013 ;Gbaguidi et al, 2015).…”

“…In recent years there has been a renewed interest in the cultivation of bambara groundnut (Ouoba et al, 2016). This is partly due to many potentialities available into the plant such as soil improvement through atmospheric nitrogen fixation (Musa et al, 2016), its importance in the food balance for populations, especially in rural areas (Bamshaiye et al, 2011), its wellbalanced chemical composition of carbohydrate 63%, protein 19% and fat 6.5% (Mkandawire, 2007;Mbaiogaou et al, 2013), its economic and social importance (Gbaguidi et al, 2015;Nadembèga, 2016).…”
