Effective and equitable trade policies can act as important adaptation strategies . Higher temperatures have had no direct effect on developed countries' exports, but have significantly reduced growth in exports among developing countries, which in turn can increase the price of goods that developed countries then import . Schenker  estimated that the climate impacts on trade from developing to developed countries could be responsible for 16.4% of the total expected cost of climate change in the USA in 2100 and, thus, North America would benefit from increased investment in effective and equitable trade policies and adaptation in developing regions. Under an RCP8.5 scenario  and within current trade integration, climate change could lead to up to 55 million undernourished people by 2050. These projections decrease by 64%  with the introduction of reduced trade tariffs and the lessening of institutional and infrastructure barriers . Although most studies focus on global food security , it is likely that the same challenges exist for other commodities and manufactured goods.
