Extreme climate events will become more frequent and force some of the current food production areas beyond the safe climatic space for production  . Globally, 10% of the currently suitable area for major crops and livestock is projected to be climatically unsuitable in mid-century and 31-34% by the end of the century under SSP5-8.5 . Adverse effects of climate change on food production will become more severe when global temperatures rise by more than 2ºC . One study estimated that the heat stress from projected 3ºC warming above baseline  would reduce labour capacity by 30-50% in Sub-Saharan Africa and Southeast Asia, leading to a 5% increase in crop prices because of higher labour cost and production losses, thereby undermining food availability, access and livelihood . Thiault et al.  projected that, by 2100, climate change under RCP8.5 could have negative impacts on both agriculture and marine fisheries productivity in countries where 90% of the world population live. A global analysis of shellfish aquaculture estimated that habitat suitability will decline beyond 2060 globally, but much sooner in some Asian countries . These negative effects in the second half of the century will be much less under RCP2.6.
