🗞️ 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 quote: “The system in the last year seems to be in a state of intense pressure, requiring immediate action from authorities.” — BEYOND Operational Unit analysis

📈 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
