Regional differences in resource availability are a key underlying driver of domestic and international trade. Climate change can change resource availability, in terms of both quantity and quality, altering trade flows, prices and incomes of producers. Climate change can also affect food access, and its stability can be affected through climate- change-driven disruption of infrastructure . Extreme events are expected to become more common as climate change progresses. Recent examples illustrate the potential for trade disruptions. In March 2019, Cyclone Idai affected 1.7 million people in Mozambique and 920,000 in neighbouring Malawi, according to United Nations  officials. The World Food Program reported that satellite imagery of flooding in central Mozambique showed an 'inland ocean' the size of Luxembourg with potentially large impacts on distribution of existing supplies, and uncertain effects on future food production and availability. The extreme rainfall events in the US state of lowa in spring 2019 destroyed large numbers of well-built grain silos. In addition, major road and bridge damage required rebuilding.
