From agriculture to food systems in the IPCC.

The change towards a food systems approach in the IPCC reflects a needed paradigm shift in the science-policy interface, and particularly in the climate change and agri-food research communities. A systems approach allows assessing simultaneously both adaptation and mitigation options and to select those more effective strategies in addressing climate change. There are still limitations that need to be addressed regarding the number of assessed crops, sectors, countries and social groups representation in order to overcome the historical epistemic injustice of the IPCC.
