Assessments on the Impacts of Climate Change on Food Production, Nutrition, Quality, and Resource Use Efficiency: A Review

Abstract

Nowadays, climate change is a hot issue all over the world which mainly affects crop production and productivity. Thus, it causes food insecurity all over the globe mainly in Sub-Saharan African countries like Ethiopia. This paper provides a comprehensive overview bonded to the appraisal of climate change impacts on nutrition, quality, and resource use, effectiveness using climate, water, and crop yield models. The studies present that climate change models with advanced spatial resolution can be a way forward for coming climate protrusions. The variability of downfall and the adding temperature was a cause of frequent failure and shortage and had a disastrous impact on the livelihood of the people. Climate change exacerbates the enormous being burden of undernutrition. It affects food and nutrition security and undermines current sweats to reduce hunger and promote nutrition. Undernutrition in turn undermines climate adaptability and the managing strategies of vulnerable populations. Climate change is now a global miracle with growth, poverty, food security, and stability counteraccusations. Because of significant dependence on the agrarian sector for product, employment, and import earnings, Ethiopia is seriously hovered by climate change, which contributes to frequent failure, flooding, and rising average temperatures. The most vulnerable sectors to climate variability and change in the country are husbandry, water, and mortal health. Agricultural sectors are severely affected by Climate change; thus, it causes the production and productivity of animals and plants. To enhance productivity, biotechnology in breeding is therefore essential; nonetheless, optimization is needed for every crop and circumstance. While some newly released crop varieties can increase yield and improve resource use efficiency, others can produce crops on marginal land that are sufficient.
