Challenges to Food Security in a Changing World

Abstract The next decades will see dramatic climatic changes and a pronounced population growth Asia—accompanied by the formation of huge human agglomerations, megacities—followed by increasing numbers of people in Africa, Latin America and the Caribbean; North America and Oceania will experience a moderate population growth whereas the EU will face a shrinking population. Unfortunately regions with the highest population growth are those were most people are living in precarious conditions especially in SS Africa and to some extent in South East Asia. To feed the 9 billion people any effort has to be undertaken to utilize and exploit the available resources in a sustainable way and to minimize the interventions into the environment. Factors of relevance are competitive biofuel production, the extension of the Food Chain into the Mega-City household, minimizing of food losses by applying new communication systems and supporting Food Sovereignty efforts of Developing countries.
