Global Assessment of Water Stress in Karst Regions in a changing world
Karst develops by the dissolution of carbonate rock. About 7–12% of the Earth’s continental area is covered by karst regions and approximately one quarter of the global population is completely or partially dependent on drinking water from karst aquifers. For the next decades, climate models predict a strong increase in temperature and a decrease of precipitation in many karst regions in the world. Despite these predictions, only few studies have quantified the impact of climate change on karst water resources, majorly due to the lack of observations and regionalisation tools.
