The agro-food value chains are complex and adaptative systems. Their characteristics change over time in response to economic, social and environmental contexts. Some of the components of the value chains, from production to consumption, change slowly, such as the social (and cultural) and geographic constraints, challenging the adaptation capacity of the primary sector to nutritional transition in an interactive and two directions process. The session intends to investigate the relationship between agro-food value chains and the nutritional transition.
The main objectives are a) to analyze the modalities of the value chain implementation, namely agents network and strategies involved; b) to understand their impacts on the socio-economic structure, appropriation process and agroforestry resources; c) to understand the extent to which value chains have contributed to changes in the food pattern in Mediterranean countries.
