Adverse Impacts of Climate Change on Food Production, Security and Food Chains

Abstract

In spite of the considerable progress in reducing hunger during last several decades about a billion people in the world are chronically undernourished. Millions of children in the world under five years hindered attaining their proper growth because of malnutrition. Billions of people lack the essential micronutrients they need to lead healthy lives. According to FAO estimation to satisfy the growing demand driven by population growth and dietary changes, food production will have to increase by about 60 per cent till 2050. It isn’t enough to have sufficient food produced globally to meet the demand, but that everybody always had access to it in the enough quantity and quality. According to the United Nations about a billion people in the world live in extreme poverty (less than 1.25 USD a day). At least 70 percent of very poor people live in rural areas and are depending partly or completely on agriculture for their livelihoods. It is estimated that about half of billion of smallholder farms in the developing world support almost two billion people. In Asia and sub-Saharan Africa these small farms produce about 80 percent of the consumed food.
