In this study, researchers found that states ranking highest in overall vulnerability often had less to do with how frequently drought occurs, and more with how prepared the state is for drought impacts. The study defined: Exposure - the frequency of drought, the states population, and the freshwater ecosystems that could be affected, Sensitivity - a states likelihood of being negatively impacted by drought, taking into account industries such as agriculture, water recreation and hydropower, Adaptive capacity - a states preparedness for drought and ability to recover, looking at the states drought plan, irrigation infrastructure and economic strength. Sources for water may include natural lakes and rivers, manmade reservoirs and groundwater. The water level in Lake Bosumtwi, Ghana, for instance, fell so low that an entire forest grew on the lakes edges. International Institute for Applied Systems Analysis.
