%T A quest to a self-sufficient and sustainable local food system: a case study of Reunion Island %L theses_frw3828 %X The COVID-19 pandemic revealed the underlying weaknesses of conventional food systems and the associated risks in terms of food security in Overseas Countries and Territories. This study establishes a comparative case study of local citizen-initiatives aiming to contribute to a more sustainable and self-sufficient local food system in Reunion Island. Local Sustainable Initiatives (LSIs) and their current food system are analyzed, as well as their interaction with institutions, using a model developed on the basis of theoretical insights. Institutional policies and subsidies promoting these types of initiatives were gathered through a content review, while in-depth semi-structured interviews were conducted with members of three initiatives. Results show that LSIs are embedded in a wider mentality shift and aim to accumulate production across initiatives to create food security at an island scale. Lastly, although some subsidies are available, the LSIs remain wary of the meddling of institutions with their work. %A Daphné Bruggemann %D 2021
