🗞️ Driving the news: Athens' water reservoirs are nearing historic lows, with the city's water supply facing significant pressure from prolonged drought conditions
• The analysis of the region's reservoirs, including Mornos, Evinos, Yliki, and Marathon, reveals that these critical water sources are at their lowest levels in recent years, signaling a growing risk of water scarcity
• Experts urge immediate action to mitigate the ongoing hydrological stress

🔭 The context: Attica’s water supply system has relied on its main reservoirs — Mornos and Evinos — for decades, with supplementary support from Yliki and Marathon
• However, in recent years, droughts, combined with high heat stress and low precipitation, have led to a steady decline in water levels
• The situation is compounded by Greece's broader water scarcity concerns, ranked 19th globally for water shortage risk due to pressures from tourism, agriculture, and aging infrastructure

🌍 Why it matters for the planet: This situation highlights the growing challenges of water scarcity exacerbated by climate change
• As the Mediterranean region faces increasingly severe droughts, the implications for water supply systems across Southern Europe are far-reaching
• Water shortages not only threaten daily life but also jeopardize agriculture, tourism, and broader economic stability
• The situation in Athens serves as a crucial reminder of the urgency of addressing water management and climate adaptation strategies in water-stressed regions

⏭️ What's next: Authorities must take immediate steps to address the critical water supply issues, possibly through improved conservation measures, infrastructure upgrades, and more sustainable water management practices
• The Mediterranean region's vulnerability to droughts necessitates long-term policy shifts and investments in water efficiency and climate resilience
• Greece, and the wider Southeastern European region, will need to adapt quickly to these emerging challenges to prevent further resource depletion

📈 One stat: In May 2025, Lake Mornos' surface area was only about 65% of its historical maximum for that time of year, marking one of the lowest levels observed in the past two decades
