Food security

The world population is expected to increase to almost 10 billion in 2050 and 11.2 billion in 2100. More than half of this growth will occur in sub-Saharan Africa, where already a quarter of the population is undernourished. As reported by the WRI, taking into account the increase of population and the shifting diets, the world would need to produce 69 percent more food calories in 2050 compared to 2006.

In this context, climate change is a further threat to food security. Unusually high or low temperatures and extreme weather events such as drought, floods and tropical storms cause huge damage to agriculture.

Indeed, FAO calculated that in developing countries the agricultural sector absorbs 25% of all the economic damages produced by climate-related disasters. In the long term, the rise of sea level, the increase of average temperatures and the change of the water cycle induced by global warming will impact food production at global level.
