Purpose The purpose of this systematic review was to assess the determinant factors of climate change adaptation (CCA) in sub-Saharan Africa (SSA). Design/methodology/approach Studies that focused on determinant factors of CCA by crop–livestock farmers and pastoralists in SSA and written in English were reviewed from five major databases using the applications of Endnote and NVivo. The review process followed a sequence of steps to reach into the final selection. Findings A total of 3,028 papers were recovered from the databases and screened for duplicates (777) and publications before 2000 (218). The titles and abstracts of 2,033 papers were reviewed, and 1,903 of them were excluded owing to preliminary exclusion criteria. Finally, 130 papers were selected for full-text review and more detailed assessment, where 36 papers qualified for the final review. The most important determinant factors of CCA by pastoralists were household income, access to information, access to extension services, government support and access to market. In the case of agro-pastoralists, access to information, household income, age and land/livestock ownership were found as the major determinant factors. Household income, land ownership, access to information, farm size, household size and access to extension services were the determinant factors found for CCA by smallholder farmers. Research limitations/implications This systematic review identified the major determinant factors according to production systems and highlights the importance of considering specific factors in designing CCA strategies. Originality/value After clearly stating the research question, a literature search was conducted from the major databases for climate-related research, and a comprehensive search was performed by two independent researchers.

The study was conducted from November 2016 to July 2017 in Mekelle, Adigrat and Southern zone (Alamata and Maychew), Tigray region, Ethiopia with the objective of assessing chicken feed, feeding management and chicken productivity. A cross sectional study using semi structured questionnaire survey and direct observation on feed (quality, formulation), feeding management (amount of feed given per chicken per day, frequency of daily feeding and type of feed transport used) and chicken productivity performance (eggs/chicken/day) was employed in a total of 31 intensive chicken farms. The collected data were analyzed using descriptive statistics, two sided t-test and oneway analysis of variance. Knowledge on raw material selection, feed formulation, quantity of feed given/ chicken/ day, frequency of feeding and cost of feed transportation are the main encountered factors by intensive chicken farmers and all revealed statistically significant effect (P<0.05) on productivity of chicken in terms of egg production. Therefore, for successful chicken production, increase their productivity and assure food security as whole; there is a need to establish chicken feed processing plants, improve feed related constraints and train farmers on feed and feeding management of the chicken.

Purpose This paper aims to understand the perception of smallholder farmers on climate change, identify major livestock related climate change adaptation (CCA) strategies and their determinants in selected neighboring districts of Tigray and Amhara regions of Ethiopia. Design/methodology/approach A total of 416 household heads were involved in a questionnaire survey using a multistage sampling approach. To understand the socio-economic factors that influence farmers’ perception on climate change (CC) and/or variability, a binary logit model was used. Multinomial logit model was used to identify the determinants of smallholder farmers’ choices of adaptation strategies. Findings Milk reduction, weight loss, feed shortage and frequent animal disease outbreak were indicated as major impacts of CC on livestock production. About 86.2% of the farmers’ exercise CCA measures where livestock health care and management (25%), followed by livelihood diversification (21.5%) and shifting and diversification of livestock species (20.9%) were the top three adaptation measures implemented. Education, knowledge on CCA strategies, access to veterinary service and extension, market access, annual income, non-farm income, total livestock unit, sex of household head and household size were the major determinant factors to farmers’ choice of CCA. Research limitations/implications Concerned authorities working in CC related sectors should give due attention to improve smallholder farmers’ access to extension and veterinary services, market access and climate information to enhance their adaptive capacity to CC impacts. In addition, incorporating climate change awareness trainings into the existing extension packages is crucial to enhance the awareness of farmers on climate change and implement appropriate adaptation strategies. Moreover, it is very essential to provide appropriate herd management and marketing strategy based on the production system to avoid the significant price reduction during drought periods. Practical implications Concerned authorities working in CC related sectors should give due attention to improve smallholder farmers’ access to extension and veterinary services, market access and climate information to enhance their adaptive capacity to CC impacts. In addition, incorporating climate change awareness trainings into the existing extension packages is crucial to implement appropriate adaptation strategies. Moreover, it is very essential to provide appropriate herd management and marketing strategy based on the production system to avoid the significant price reduction during drought periods. Originality/value This research is focused on smallholder crop-livestock farmers, livestock-based CCASs and presents the determinant factors to their choice of adaptation.
