Southern Europe is experiencing more extreme heat waves and longer droughts due to climate change and water over-consumption, with agriculture being the largest user of water. The situation is particularly severe in northern Italy, where the government has declared a state of emergency and banned certain water uses. Portugal has also declared an emergency and restricted hydroelectric power use to conserve water. Spain is dealing with extreme dryness, with 70% of its agricultural production at risk due to water shortages. Greenpeace Spain has criticized the lack of water-saving policies and emphasized the need for more efficient water infrastructure.
