“…Ce résultat était prévisible puisque la pluviométrie est le facteur climatique le plus important qui influence les activités agricoles (Nhemachena et al, 2014). L'importance de la pluviométrie a été déjà évoquée dans d'autres cultures telles que l'igname , le riz (Nwalieji et Uzuegbunam, 2012) et même le niébé (Hall, 2011).…”

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 adaptatives localement utilisées, 40 villages sélectionnés dans différentes zones agroécologiques du Bénin ont été prospectés. Des méthodes d'analyses qualitatives et quantitatives ont permis de comprendre que les attaques des insectes aux champs et au cours de stockage restent les contraintes prioritaires. L'analyse du choix des méthodes d'adaptation face aux changements climatiques a montré que l'âge du producteur de niébé affecte de façon positive l'adoption des pratiques culturales (p<0,05) et des stratégies multiples (p<0,1) ; le sexe influence de façon significative (p<0,001) mais négative le choix des producteurs de voandzou à utiliser des variétés résistantes et de multiples stratégies. Le nombre de manoeuvres utilisé par ces producteurs influence de façon significative le choix de multiples stratégies (p<0,001). Des programmes nationaux de lutte contre les effets liés aux changements climatiques sont à mettre en place afin de préserver les ressources génétiques de niébé et du voandzou au Bénin. © 2015 International Formulae Group.

Walp.) and Bambara groundnut (Vigna subterranea (L.) Verdc.) in Benin ABSTRACTThe existence of harmful impacts of climate change on the agricultural production in sub-Saharan Africa is now firmly established. To document endogenous knowledge relating to the climate change, to identify the constraints which are associated to it and which jeopardize the production and the diversity of cowpea and Bambara groundnut in Benin and to examine the adaptive strategies locally used, 40 villages selected in various agro ecologic areas from Benin were surveyed. Methods of qualitative and quantitative analyses made it possible to understand that the attacks of insects to the fields and during storage remain the priority constraints. The analysis of the choice of the methods of adaptation as regards to the climate changes showed that the age of the producer of cowpea affects in a positive way the adoption of the cultivation methods (p<0.05) and multiple strategies (p<0.1); the sex influences to a significant degree (p<0,001) but negative the choice of the producers of Bambara groundnut to use resistant varieties and multiple strategies. The number of opera...

“…Those identified in this SLR consist of the local community or the farm level as outlined earlier. With the aim of improving adaptive capacity at the household and farm level, Nhemachena, Hassan and Chakwizira [34] point to the need for government policies to support research and development that supply farmers with the appropriate technology, the enhancement of crop development, provision of climate information as well as financially supporting specific adaptation measures such as irrigation.…”

“…Human development, health and education are the remaining indicators used in identifying Morocco with the lowest adaptive capacity [48]. In identifying specific indicators of adaptive capacity, the authors refer to institutional performance, of which the level of corruption is a key indicator, as well as the availability of knowledge and new technologies [34,48]. A combination of high exposure to climate change, high sensitivity and low adaptive capacity is argued to constitute a highly vulnerable community to the effects of climate change [48].…”

“…A combination of high exposure to climate change, high sensitivity and low adaptive capacity is argued to constitute a highly vulnerable community to the effects of climate change [48]. Nhemachena, Hassan and Chakwizira [34] refer to evidence from their analysis of farmers from South Africa, Zambia and Zimbabwe as to their perceptions of adaptation determinants, lending credence to the importance of 'specific' adaptive capacity. Their research looks at responses of farmers, highlighting the need for increased credit, access to information (both climate and agronomic) and increased market access, to increase their adaptive capacity [28,34].…”

Climate security and a vulnerability model for conflict prevention: a systematic literature review focusing on African agriculture

Background: Climate change poses credible threats to the livelihoods of many. This paper addresses how climate change adaptation can help counter the increased risk of violent conflict that is associated with these climatic changes. Extant climate-conflict links however, involve a complex interaction of many factors that mediate the impact of climate change. Thus, adaptation methods should not focus simply on the direct impacts of these changes. Methods: This paper, using the Systematic Literature Review method, conducts an analysis of the climateconflict and climate adaptation literature covering 46 papers, with a geographical restriction of Africa and focusing on the quantitative comparative literature. Results: This SLR had two key aims, first to understand how links and common areas of understanding between the climate-conflict and climate adaptation fields of research could inform future empirical quantitative research into the notion of climate adaptation as conflict prevention. And secondly, how future quantitative comparative climate conflict research could be informed. It suggests a Vulnerability Model that assists in understanding how vulnerability, understood through the lens of exposure, sensitivity and adaptive capacity, can provide researchers and policy makers with the various factors, both direct and indirect, which can identify where violent conflict might occur. Simultaneously, it illustrates what factors influence the adaptation needs of an agricultural community and hence how adaptation could reduce the risk of future violent conflict. Future quantitative comparative climate-conflict research could also benefit by using disaggregated sub-national data, focusing on agricultural communities using variables that draw on the Vulnerability Model.

“…Recent research efforts on climate change impacts and adaptations have focused on regional and national assessments of the potential effects of climate change on agriculture [12,13]. The present study focused on specific locations using a bottom-up approach which seeks to gain insight from the farmers themselves based on a farm housed hold survey.…”

Citation: Mutunga EJ, Ndungu CK and Muendo, P (2017) AbstractThe effects of climate change have highly challenged the productivity of the agricultural sector. The increasing temperatures and erratic rains, as well as diseases and pests have significantly reduced crop yields in the arid and semi-arid regions of Kenya. Though climate change has been the talk of the day, many farmers in the grassroots have hardly adopted any response options and have continued to suffer losses from the inherent effects of climate change. The present study sought to assess the perceptions of small scale farmers on climate change in selected villages in Kitui County and identify adaptation measures adopted by the farmers in response to climate change. Descriptive survey design was used. A total of 177 households were randomly selected to constitute the study sample. Data was coded and analyzed using SPSS version 20. The results showed that most farmers had perceived a changing climate with 74% and 100% of the respondents in Kaveta and Mikuyuni villages respectively, reporting an increase in temperature over the years. Regarding precipitation, 100% and 97% of the respondents in Mikuyuni and Kaveta villages respectively, had noticed a decrease in the average annual rainfall over the last two decades. Further, the results indicated that 76% and 88% of the respondents in Kaveta and Mikuyuni villages respectively had adopted various adaptation options in response to the decreasing rainfall and the unpredictable onset of rains. The study established that farmers in drier areas perceived climate change more and had adapted more to climate change and variability as compared to those in wetter areas. More resources in terms of credit facilities, access to climate change information and extension services should be availed to farmers in areas affected more by climate change and variability to increase their resilience.
