In this globalised world the importance of territorial boundaries is diminishing and individuals are increasingly affected by actions taken by non-state actors and by states other than their own, causing a growing gap of human rights protection. The purpose of this thesis is to determine whether extraterritorial obligations of economic, social and cultural rights, and especially of the right to food, exist, and if so, what their nature, extent and content is. The thesis focuses on the position of extraterritorial obligations in international law, identifies how globalisation has affected the need for extraterritorial obligations and assesses whether the concept of extraterritorial obligation is compatible with the principle of sovereignty. After defining the legal foundations of extraterritorial obligations, the different levels of obligations are examined, with a focus on the tripartite typology of obligations (respect, protect, fulfil). It will be discussed whether these obligations emerge only through unilateral action or also within bilateral and multilateral cooperation. Following an examination of the legal foundations and the normative content of the right to food, the focus lies on three case studies, which comprise vulnerable food markets and subsidies, the problems arising if markets are challenged by overproduction and import floods, and the food crisis in the Horn of Africa. Each extraterritorial obligation (to respect, to protect and to fulfil) will be clarified and analysed by one corresponding case study, and the thesis shows that extraterritorial obligations exist, evaluates their respective binding nature, and discusses under which circumstances there might be a violation of the extraterritorial obligation to respect, protect or fulfil the right to food.
