During the last two decades, 200 million have been lifted out of hunger and the prevalence of chronic malnutrition in children has decreased from 40 to 26 percent. In spite of this progress, according to the World Bank, 102 million people still live in extreme poverty and according to this year’s report, on the safety of food insecurity in the world. 793 million people are undernourished.
Climate change exacerbates the risk of hunger and under nutrition through. Climatic change increases the frequency and intensity of some disasters such as droughts, floods and storms. This has an adverse impact on livelihood and food security. Climate related disasters have the potential to destroy the crops, critical infrastructures, and key community assets, therefore deteriorating livelihoods and exacerbating poverty.
Long term and gradual climate risks sea level will rise as a result of climate change, affecting livelihood in coastal areas and river deltas. Accelerated glacial melt will also affect the quantity and reliability of water available and change patterns of flooding and drought.
Climate change affects the all dimensions of food security and nutrition. Changes in climatic conditions have already affected the production of some staple crops, and future climatic change threatens to exacerbate this. High temperatures will have an impact on yields while changes in rainfall could affect both crop quality and quantity. Climate change could increase the prices of major crops in some regions. For the most vulnerable people, lower agriculture output means lower incomes. Under these conditions, the poorest people, who already use most of their income on food, sacrifice additional income and other assets to meet the nutritional requirements or resort to poor coping strategies.
Climate related risks affect calorie intake, particularly in areas where chronic food insecurity is already a significant problem. Changing climatic conditions could also create a vicious cycle of disease and hunger. Nutrition is likely to be affected by climatic change through related impacts on food security, dietary diversity, care practices and health.
The climatic variability produced by more frequent and intense whether events can upset the stability of individuals and government food security strategies, creating fluctuations in food availability, access and utilization
