TransIndiandairy addresses technical, organisational and institutional levers to upscale agroecological transitions. It does it by developing a multiscale framework on institutional resources regime guiding the analysis (both qualitative and quantitative) and supporting the integration of results. Indian dairy systems are chosen as case study for their local and international importance and for the unprecedented scale of their transition. Concretely, the team of 12 social and biotechnical scientists will analyse the coevolution between the business models involved in the production, processing and marketing of dairy products in three Indian states (WP1) and the multiscale governance of the transitions (WP2). It will also assess the systems multidimensional performance (matter and energy flows, value creation and distribution, resilience) (WP3). Project outcomes will be both scientific (articles, report, PhD) and operational (unlocking, knowledge spreading, scientific cooperation).
