By mid-2026, a severe drought and record tourism have triggered water emergencies across numerous Greek islands, including Astypalaia, Karpathos, Leros, Patmos, Symi, Tinos, Alonnisos, Meganisi, and others. The crisis is driven by rising temperatures, declining rainfall, and a surge in visitors; for instance, Mykonos reported a nine-fold increase in consumption. Experts warn that the situation is structural, noting that up to 60% of water is lost to leaks in aging networks.

In response, the Greek government has allocated over €15 million for desalination, reservoirs, and grid upgrades across nine islands. Significant projects include a 1,050 m³ per day desalination plant in Katapola, Amorgos, and a 600 m³ per day unit in Meganisi. On Astypalaia, the Frágma reservoir has dropped to one-sixth capacity, prompting the use of a provisional desalination plant and causing residents to rely on bottled water due to quality concerns.

Beyond the islands, broader water security issues have emerged. A study found snow cover on ten Greek mountains has halved since the mid-1980s, threatening mountain reservoirs and winter tourism. Meanwhile, MEP Dimitris Tsiodras has urged the European Commission to address the €23 billion annual investment gap for water management in island regions. While desalination provides relief, officials emphasize it is an energy-intensive emergency measure rather than a permanent solution.
