Human activity has pushed the Earth’s freshwater resources far beyond the stable conditions that prevailed before industrialisation, a study has found.
The findings, published in the journal Nature Water, show that the updated planetary boundary for freshwater change was surpassed by the mid-twentieth century.
This is the first time that global water cycle change has been assessed over such a long timescale with an appropriate reference baseline, the researchers said.
Human pressures, such as dam construction, large-scale irrigation and global warming, have altered freshwater resources to such an extent that their capacity to regulate vital ecological and climatic processes is at risk, they said.
