How does climate change threaten food and nutrition security?
Deterioration of the land, destruction of harvests, salinization of freshwater,, reduction of both arable and pasture lands, floods and droughts increasingly more frequent and intense: the impacts of climate change will tax the four pillars of food security i.e. availability, access, stability and use.
Without real efforts towards adaptation, the populations’ production capacity and livelihoods are under serious threat. According to the International Panel of experts on Climate Change (IPCC) forecasts, every decade will see the main crop yields (wheat, rice, corn…) cut down by 2 %1. Climate change will restrict proper access to food and reduce food quality, aggravating the prevalence of infectious, vector-borne diseases. Thus, 5 to 6 billion people, that is 50 to 60% of the world population, will be exposed to dengue by 2085, further degrading their nutritional status
Through its impact on agriculture and food security, climate change could leave an additional 600 million facing acute malnutrition by the 2080s over and above the level in a no-climate change scenario.

As six months remain until the COP21, and hardly a few days until the Bonn negotiations on the Paris agreement, government representatives, researchers, civil society organizations from North to South gather to discuss what is at stake regarding the reference to food and nutrition security in the Paris agreement. Civil society calls for clear commitments in order to ensure consistency within the considered solutions to tackle climate changes and meet the challenge of hunger.
