The nicknames of the world’s biggest rivers give a sense of how we feel about them: “the great river”, “the river that swallows all rivers”, “Mother Ganga” and “Old father Thames”.

They’re nerve endings, elders and sources of comfort, but also of awe and respect.
And yet many of the world’s rivers are suffering, hit by multiple environmental challenges. A new report out today from the World Meteorological Organization finds that rivers across the world experienced one of the driest years in more than three decades during 2025.
