Abstract:
Global climate change is largely the result of human activities such as burning fuel, agricultural practice, deforestation, industries and etc. It has been resulting significant impact on agriculture, water sources, food security and human health especially in African countries. So, the objective of the review was to explore the cause of climate change, its impact on farming components and food security, management strategies and present updated information. The sectors like crop, livestock, fisheries, aquatic culture, forestry ecosystem and food systems are sensitive to weather and directly affected by climate change. Since the 1980s, 10% of yield declines globally for cereal crops in every 1oC warming specifically for wheat, rice and maize in 6, 3.2 and 7.4% percent respectively. Regarding livestock, the climate change affect animal growth, reproduction, metabolic activity, milk production and reduce feed resources for animals. The challenge of climate change in all sectors exacerbates food insecurity, and need mitigation as well as adaptation practice to reduce or alleviate its impact. In summary, as the earth will continue to warm considerably more over the next few decades to centuries there should be technological or policy changes to reduce emission and alleviate further globally averaged warming.
