Sustainable Diets 4 All SD4ALL builds the advocacy capacity of CSOs to challenge unsustainable practices and incentives in food production and consumption. The program takes evidence - especially that generated by citizens - directly to policymakers and international institutions so their policies, market practices and legislation will promote diets that are diverse, healthy, fair and based on environmentally sustainable production methods. One of the principal strategies is to set up Food Change Labs to bring multiple stakeholders together to share knowledge, evidence and ideas, and to jointly develop local, national and international examples of how food systems can be transformed.
