Since the end of the last century, the global environmental footprint of humanity has exceeded the planet’s resources, and increases every year. Food systems are a major factor in all this. More specifically, food security is a systemic issue of the highest importance. It is a real challenge to prepare to feed 9 billion people in a few decades and deal with malnutrition, aware that resources are both finite and compromised by climate deregulation. 
Food security exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food which meets their dietary needs and food preferences for an active and healthy life.” According to the FAO, the different components of food security concern access to food, its availability and quality, and its nutritional, health, cultural and even hedonistic aspects. Today, all of these aspects, to some degree, are subject to a series of interdependent transitions: the globalisation of the economy, demographics, urbanisation, nutrition, environment, energy, climate, etc. 

World food security can only be achieved by looking at the food system as a whole and by working on the different stages of production, transformation, distribution and final consumption as well as on trade, regulatory mechanisms and recycling. Similarly, agricultural biomass has always contribut-ed to human nutrition – tomorrow’s main priority – as well as to animal nutrition, the production of materials, chemical compounds and energy (« food, feed, fiber and fuel »).

INRA must help produce the new knowledge necessary to achieve global food security by 2050, without pre-empting the natural resources of future generations.
