ICAD aims to re-articulate visions and projects for a more sustainable food procurement system at the scale of a territory. We define such systems as constructed by actors who coordinate their purposes, actions and resources within a circumscribed physical, cultural, economic, social and political space which evolves over time. ICAD main goal is to contribute to highlighting how, on the scale of a territory undergoing urbanization and demographic growth, a large set of stakeholders such as private caterers and their suppliers, as well as various non-profit associations willing to maintain agriculture and the natural heritage, develop sustainable food systems which integrate local production or other territorialized services in short or long circuits to provide food at workplace. Under this overarching goal, the project has three main objectives: (a) Establishing what ‘more sustainable food’ means to the stakeholders (including eaters) in institutional catering and how it is achieved ; (b) Analyzing the evolution of work in the socio-technical systems, their actual contribution to the desired sustainability, their interaction and the role of coupled innovations in these transformations ; (c) Supporting and analysing a systemic collective and territorial design process for the supply of sustainable food at workplace within a territory. ICAD will be conducted by an interdisciplinary team (agronomists, nutritionists, LC analysts, economists, management scientists and ergonomists) in relation to the actors involved in the Territorial Food Project of the Plateau de Saclay and its neighbourhood. This geographic area, located in Ile-de-France, has experienced a massive influx of employees over a short period of time. Many of these newcomers have a high education degree and a great environmental awareness which, combined with the questioning of globalized systems activated by the Covid crisis, implies a demand to redesign and rebuild the food supply chains to provide sustainable food at workplace. We are therefore at an opportune time to imagine the inclusion of new products and services for sustainable food in collaboration with territorial actors as well as actors from the catering industry. ICAD is split into four work packages. WP0 is dedicated to project management, interdisciplinary work for data collection and analysis; and dissemination of the project results. WP1 is organized to grasp the different ways that stakeholders understand sustainability, as well as the different criteria they use to achieve the desired sustainability. WP2 is meant to understand the evolution of the networks that contribute to a sustainable supply of food products and services through the study of the practices and motivations of actors (i) involved in food circuits to develop sustainable food procurement; (ii) involved in public policy support to such circuits. WP3 aims to support the stakeholders of the Plateau de Saclay and the adjacent local authorities in a step-by-step collective and territorial design process, the purpose of which is to debate and identify actions to be taken to contribute to sustainable food procurement at territorial level. This interdisciplinary and transdisciplinary work is meant to draw lessons on this specific case to build more generic knowledge on the management of transition towards more sustainable food systems. In particular it will contribute (i) to explore the characteristics of the emergence and development of relevant coupled innovations to foster sustainable food supply systems; (ii) to identify the obstacles and the present opportunities to be seized to facilitate such systems in in a context of strong urbanization.
