Global demand for animal products is extremely increasing in the future period, which mainly because of improvement in the global standard of living. In the meantime, global climate change is a pressure to animal production due to the impact on quality of forages, water availability, animal and milk production, animal health, animal reproduction and biodiversity. This paper reviews the impacts of climate change on animal production and converse contributions of animal production sector to global climate variation and specific climate change adaptation and mitigation strategies in animal production sector. Global climate change will affect animal production and consequently food security mainly in tropical regions. This paper also reviewed that, converse contribution of animal production sector in emission of GHGs to the atmosphere for global climate change. Therefore, global climate change adaptation, mitigation practices and policy frameworks are critical to protect animal production. [ABSTRACT FROM AUTHOR]

Background: An effort was made by the Ethiopian government to increase the level of technical efficiency of farmers across the country. However, due to climate change, smallholder farmers were facing challenges to increase technical efficiency in crop production. Adaptation to climate change is crucial to uphold and increase food crop productivity. This study analysis the impact of climate change adaptation and policy issues on food crop production efficiency in Kellem Wollega, Ethiopia. Methods: The data was gathered from 400 randomly selected food crop smallholder farmers. The Cobb-Douglas production function was used by including the climate change adaptation measures as explanatory variables in technical inefficiency. Simulation was made to adaption measures that can be influenced by the policy variables to see their impact on the level of technical efficiency. Result: The finding show that the use of adaptive practices (multiple crop type, improved crop varieties, adjusting planting dates and irrigation) had a significant and positive effect on technical efficiency whereas land fragmentation reduces efficiency level. Regarding simulation of policy variables the result show that the mean technical efficiency would increase with rising level of improved crop varieties, adjusting planting dates and irrigation practices. The results of the simulation of land fragmentation climate change adaptation variables show that the mean technical efficiency declines as a result of land fragmentation. Empirical results reveal that with appropriate policy intervention (climate change adaptation measures) the technical efficiency level of food crop farmers can be enhanced. [ABSTRACT FROM AUTHOR]

Background: In contemporary world food crop production is under pressure due to change in climate. In developing nation climate change is a treat both in food crop production and food security. Analysing farmers' climate change adaptation measures and understanding the barriers provides clear guidance to address constraints that impede food crop producers' adaptation. Methods: A stratified random sampling technique was used to sample 200 food crop producers for primary data gathering. The multinomial logit model was used to determine the factors that affect the selection of adaptation measures to climate change and factor analysis was used to identify factors that impede food crop producers' ability to adapt to climate change. Result: The result of the multinomial logit model shows that various socio-economic factors (family size, education, climate change awareness, farming experience, nonfarm income, farm size, distance to farmland, extension services and access to credit) influence farmers' choices regarding climate change adaptation strategies in the study area. The result of the varimax rotate principal component analysis found four factors that are detrimental to food crop producers in adapting to climate change. These principal constraints are institution and government, technology and inputs, information and knowledge and belief, culture and participation as factors that hinder farmers from adapting to climate change. Thus, there is room for government and development partners to strengthen the adaptive capacities of farmers by resolving problems related to institutions, government policy, technology, inputs availability and information regarding climate change to minimize the potential impact and loss in the future.
