Climate Change Effect and Crops Adaptations in Ethiopia: A Comprehensive Review

Kadir Erbo, Fikirte Assefa

Climate change is one of the serious problems in crop production. The increase in carbon dioxide level from 280µg/g to 387µg/g is associated with the global temperature. Human activities release greenhouses gases into the atmosphere. Projected increases temperature, changes in precipitation pattern, changes in extreme weather events, and reduction in water availability may all result in decline crop productivity. The IPCC estimated that a global temperature increases by 1.1 to 6.4°C and also, precipitation, wind shift and other measure of climate change will be occurred in the future. These changes are direct, indirect and socio-economic impacts on crop production. Different study showed that climate change impacts on fruit growth, crude initiations, bulb development, grain yield, biomass formation are direct effect on physiological, morphological, phenotypic changes which may results on crop productivity. Adaptations strategies involve in climate change such as shifting planting time, using improved varieties such as drought resistance, new in Janation, precious management, integrated weed management, pit planting of sugarcane, in addition to these other strategies like improving existing cultivars and new crops and devising new systems and method of managing crops. The main review this paper to summarize that understanding the physiology, morphology and molecular level of plant in climate change, using new knowledge translate, working in collaboration between research and development and using genetic engineering approach will improve further to adopt climate change.
