FALAH (Family farming, lifestyle, and health) is a multidisciplinary project focused mainly on family farming and food in the Pacific Islands. Due to the close relationship between agriculture and food, the project is structured into three complementary scientific components. The scientific results of the research work carried out in the two thematic work packages (food and agriculture) will largely feed into the third working group based on knowledge exchange and communication. The project involves some fifteen multidisciplinary teams at local, regional, and international networks. This network-networking project mobilizes researchers and teaching-researchers from Europe and partners from Vanuatu, Fiji, Salomon, New-Caledonia, and Australia. During this project, three times phases are planned at different levels between 2020, 2021, and 2022. In each phase, joint meetings in the form of workshops or conferences are planned for the work packages. At the same time, common areas of experimentation / exploration for future research are planned on the Pacific Fields of application (Fiji, Solomon, Vanuatu and NC). The secondments of the members of the scientific teams are defined on the basis of these joint meetings. The main objective is to build a network of research teams operating in the Pacific Islands that have a common interest in food security and its direct or indirect relationship with the environment, lifestyle and health. The final goal is to promote and revitalise family agriculture to improve the health of Pacific populations and ensure food security in the context of rapid social and economic transformations and climate change, which effect are particularity harmful to Pacific islands.
