When hazard, vulnerability and exposure are considered together, drought risk is lower for sparsely populated regions, such as tundra and tropical forests, and higher for populated areas and intensive crop and livestock farming regions, such as southern and central Asia, southeastern South America, central Europe and the southeastern USA . Dynamics in exposure and vulnerability are rarely addressed . Quantifying economic vulnerability to drought in terms of damages as a percentage of exposed GDP, Formetta and Feyen  show a disproportionate burden of drought impact on low-income countries, but with a clear decrease in global economic drought vulnerability between 1980-1989 and 2007-2016, including a convergence between lower-income and higher-income countries due to stronger vulnerability reduction in less-developed countries. Nevertheless, during 2007-2016, economic vulnerability to drought was twice as high in lower-income countries compared to higher-income countries .
