Roughly half of the planet’s inhabitants is going through grave water shortages, with local weather change-linked droughts affecting greater than 1.4 billion folks between 2002 and 2021, the report for the UN cultural company UNESCO mentioned.

As of 2022, greater than 2 billion folks have been with out entry to soundly managed consuming water, whereas 3.5 billion folks lacked entry to first rate bathrooms, it added.
On high of that, prescribed drugs, hormones and industrial chemical compounds are seeping into the world’s rivers.
The report, titled “Water for prosperity and peace”, referred to as for extra water schooling, knowledge assortment and funding to deal with the disaster.
It additionally highlighted the bounds of recent computer-led options.

“An array of applied sciences is on the market to enhance each water provide, water use effectivity and the standard and extension of” sanitation providers, it mentioned.However “a number of quickly rising applied sciences are extremely water-intensive and, if left unchecked, may result in critical issues within the close to future.”
Synthetic intelligence (AI) had “the potential to boost (river) basin administration, emergency response, and the operation and upkeep of water provide and wastewater therapy vegetation,” mentioned the report.
However “AI and associated applied sciences require giant volumes of water for laptop cooling methods, along with the (typically water-intensive) power required to energy the tools.”
Flawed options
Whereas local weather change is projected to accentuate patterns of file rainfall and drought in coming years, options to deal with that downside have been additionally utilizing up an excessive amount of water, it added.
One such approach, referred to as carbon seize and storage, syphons off CO2 from the exhaust of fossil fuel-fired energy vegetation and heavy business equivalent to metal and cement factories in a bid to scale back planet-heating carbon air pollution.
However “carbon seize and storage methods… are extraordinarily energy- and water-intensive,” the report mentioned.
Vitality manufacturing accounts for between 10 and 15 p.c of worldwide water withdrawals, each to extract fossil fuels and funky thermal and nuclear energy stations, it mentioned.
Whereas wind, photo voltaic and geothermal power methods are extra water-efficient, they nonetheless require lithium batteries for energy storage.
But the extraction of lithium and different crucial minerals for photo voltaic panels “is often extremely water-intensive, with vital dangers to water high quality” particularly groundwater, ecosystems and native populations, the report mentioned.
