Freshwater is disappearing from lakes and rivers across the globe at an alarming rate, driven by climate change and unsustainable land use, according to a new analysis of satellite images.
The study identifies 10 critical hotspots where water bodies have shrunk dramatically over recent decades. From the Aral Sea in Central Asia to Lake Mead in the United States, these areas highlight the growing pressure on the world's freshwater resources.
"What we are seeing is a planetary-scale shift in water availability, with profound implications for ecosystems and human communities," said a lead researcher.
The images capture stark before-and-after contrasts: reservoirs reduced to mudflats, vast inland seas transformed into desert, and rivers running dry. The findings underscore the urgent need for better water management and climate action.
Key locations include:
- The Aral Sea (Kazakhstan/Uzbekistan): once the world's fourth-largest lake, now nearly gone due to irrigation.
- Lake Chad (Africa): shrunk by 90% since the 1960s.
- The Colorado River Basin (USA): reservoirs like Lake Mead at historic lows.
- The Mesopotamian Marshes (Iraq): drained and dried.
Without intervention, scientists warn that water scarcity will worsen, affecting billions of people and accelerating biodiversity loss.
