I have read with a lot of interest the different contributions, learnt a lot and had the pleasure to come across old friends. But I wonder if innovation in agriculture (instead of a food system approach) was not too narrow an entry point. We must move beyond the classical supply-driven value chain/commodity approach and revisit production systems from the demand side; re-localize development efforts, support family agriculture and aim for resilient food systems which make the best of existing resources (including indigenous knowledge).
Local government – and in an increasingly urbanized world, cities – should take the lead and engage in sustainable territorial planning in consultation with all relevant actors, aiming at food security and environmental sustainability in both rural and urban areas, while protecting and creating decent jobs and fulfilling human rights. Economics are important but there are only one dimension; health staff, sociologists, agronomists, environmentalists and economists must join forces to address complexity and learn together from existing practice.
Food-based nutrition education (in particular cooking demonstrations) can lead to changes in household food production. The promotion of sustainable diets constitutes the logical entry point and goal for sustainable food systems and a long-term solution to malnutrition.
