The agricultural sector in Rwanda is the engine of economic growth and modernization. This study examines the role of community based organizations (CBOs) in transferring climate change information to farmers’ communities in Rwanda. Materials and Methods: Three districts (Kirehe, Rwamagana and Ngoma) were studied and two active CBOs (RWIRRI and RADO) were selected for data collection. A total of 100 farmer households were interviewed. A focus group discussion of fifteen participants was conducted in the community. Results: The results showed that the CBOs played a good role in increasing farmers’ awareness related to climate change and adaptation strategies. CBOs had built a capacity in the local communities regarding improved agricultural methods, climate variability and climate change effects. The adaptation strategies could improve the livelihood conditions of the communities. Conclusion: CBOs had played a role in increasing farmers’ awareness and had built their capacity regarding to climate change and crops productivity.

There is broad interest in the impacts of some climate parameters on agriculture in Sub-Saharan Africa and on the most effective efforts to assist adaptation to these changes, yet the scientific basis for evaluating production risks and prioritizing some specific climate variables have been quite limited. This study assessed the impacts of temperature and rainfall on the yield of two major crops (cassava and maize) in Port Harcourt for the period of 2005-2009 spanning 5 years. Materials and Methods: Temperature and rainfall used for the study were sourced from the archive of the Nigerian Meteorological Agency, Lagos and crop yield data of cassava and maize sourced from the agricultural development programme Port Harcourt using statistical correlation analysis. Results: The study revealed that the temperature has a negative relationship with the yield of both cassava and maize, therefore, indicating that as temperature decreases, the yield of both cassava and maize increases, which means that the minimum temperature plays a significant role in the growth of cassava and maize in Port Harcourt. While rainfall has a moderate influence on the yield of both crops, indicating that high rainfall amount may have a negative impact on the crop yields. Conclusion: The response of crop yields to maximum high temperature might have an adverse effect on agricultural production in the study area, which is not good as it may lead to the shortage of food, hunger and food insecurity in the study area. The study provides insight into the significant impacts of the temperature and rainfall on cassava and maize yield in the study area.","PeriodicalId":92133,"journal":{"name":"Research journal of chemical and environmental sciences","volume":"27 1","pages":"137-142"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78501814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
