Food security and climate change
With many of the resources needed for sustainable food security already stretched, the food securitychallenges are huge. Climate change will make it even harder to overcome them, as it reduces theproductivity of the majority of existing food systems and harms the livelihoods of those alreadyvulnerable to food insecurity. The likelihood of the nations of the world being able to meet the 2°Ctarget of maximal average temperature rise set by the UNFCCC negotiations in Cancun is diminishingwith time. If negotiations for global climate policies fail, temperature rises of the order of 4°C by theend of the century, corresponding to the best estimate of the higher emissions scenarios of the IPCC,cannot be discarded. While some might benefit, people in some regions will be affected more thanothers by changes in average temperature and precipitation. In addition, the likelihood of increasedvariability and extreme events means that management of risk, both locally and internationally, will beeven more important than it is today.
