River flows around the world fell to all-time lows last year amid record heat, endangering water supplies in an era of growing demand, a UN weather agency report showed on Monday.
Prolonged droughts cut river flows in large parts of North, Central and South America, with the Mississippi and Amazon River basins reporting record low water levels in 2023, according to the State of Global Water Resources report based on data going back 33 years.
The Ganges and Mekong River basins also experienced below-average conditions. Overall, 50 per cent of global catchment areas showed abnormal conditions, with most being in deficit and reducing water availability for agriculture and industry.
“Water is becoming the most telling indicator of our time of climate’s distress and yet, as a global society, we are not taking action to protect these reserves,” World Meteorological Organization (WMO) Secretary General Celeste Saulo told reporters at a Geneva press briefing.
“Water is the canary in the coal mine of climate change. We receive distress signals in the form of increasingly extreme rainfall, floods and droughts which wreak a heavy toll on lives, ecosystems and economies,” Saulo said.
She warned that water cycles were becoming more erratic due to climate change and called for increased hydrological monitoring to track and respond to the changes.
