CLIMATE LECTURE 18: Climate Change Challenges to Agriculture, Food Security, and Health by:2 (Source: Crossref)

    We have learned from our brilliant and dedicated colleague, David Rind, that the already-evident and further-anticipated process of anthropogenic climate change raises worldwide concerns regarding agricultural production, food security, and public health. The four pillars of food security — its availability, accessibility, utilization, and stability — will all be affected by the expected changes in climate over the coming century. At both global and regional scales, the Intergovernmental Panel on Climate Change (IPCC) has demonstrated that the provision of food security and maintenance of ecosystem services are under threat from dangerous human interference in the Earth’s climate (Porter et al., 2014). The FAO emphasizes that the main cause of hunger and malnutrition is not the lack of food per se, but the inability of vulnerable groups to access food in many circumstances (FAO, 2014). Furthermore, the IPCC has determined that global food prices will likely increase by the year 2050 as a result of changes in temperature and precipitation (Porter et al., 2014; Nelson et al., 2014). At country scales, nations are concerned over potential damages that may arise in coming decades from climate change impacts on agriculture and the food system, as these are likely to affect their citizens’ well-being, regional planning, resource use, trading patterns, and international policies…
