Due to its particular combination of multiple strong climate hazards and high vulnerability, the Mediterranean region is a hotspot for highly interconnected climate risks. The main economic sectors in the region  are highly vulnerable to climatic hazards, while socioeconomic vulnerability is also considerable. The low-lying areas are the most vulnerable areas for coastal climate-related risks  and other consequent risks  . Climate change threatens water availability, reducing river low flows and annual runoff by 5-70%, reducing hydropower capacity . Yields of rain- fed crops may decrease by 64% in some locations . Ocean warming and acidification will impact marine ecosystems, with uncertain consequences on fisheries . Desertification will affect additional areas, notably in the south and southeast . Burnt area of forests may increase by 96-187% under 3ºC, depending on fire management. Beyond 3ºC, 13-30% of the Natura 2000 protected area and 15-23% of Natura 2000 sites could be lost due to climate-driven habitat change .
