Today, food insecurity affects more than 800 millions of people and exhibits itself in various forms (malnutrition, “hidden hunger”, etc.). These phenomena are aggravated by climate change. Hence, the reinforcement of food and nutrition security is at the heart of the issues of local economic development, and it concerns not only urban areas, but also the future of agricultural and rural areas everywhere in the world. Food related activities are extremely diverse (agriculture, but also agri-food industries, retail, catering, and others services) and food security is a global issue that concerns many stakeholders (involved in agriculture, industry, retail, education, health, culture, and environment). In that sense, it is a key dimension of strengthening local and regional authorities, which themselves must consider this issue in relation to their reflection on a new model of development based more on local actors. In this context, the main objective of the session is to examine the relationship between food and nutrition security and local economic development while taking into consideration the role of local and regional authorities.
