Freshers' Week 2011 Sustainably reducing world hunger was one of the key challenges. The aim was to develop future-oriented project ideas within the understanding of social entrepreneurship. Food security According to current projections, the world population will have grown to nine billion people by 2050, with the largest growth in developing and newly industrialised countries, which is accompanied by a change in lifestyles and dietary patterns. Reasons for the occurrence of hunger in the population are mostly found in the agricultural and economic development of a country. Natural resources such as clean water and climatic conditions also play a significant role. Already today, the global food production is able to feed around twelve billion people, but food security involves not only the availability of food, but also its preparation and distribution. The aim of the case study As part of the case study, the students were offered the opportunity to examine the current and complex subject of "food security" using case countries Bangladesh and Mozambique. The problem areas were highlighted, actors introduced and own project ideas developed for the reduction of hunger.
