Poor data on groundwater jeopardizes climate resilience


Rebecca Root at Devex: “A lack of data on groundwater is impeding water management and could jeopardize climate resilience efforts in some places, according to recent research by WaterAid and the HSBC Water Programme.

Groundwater is found underground in gaps between soil, sand, and rock. Over 2.5 million people are thought to depend on groundwater — which has a higher tolerance to droughts than other water sources — for drinking.

The report looked at groundwater security and sustainability in Bangladesh, Ghana, India, Nepal, and Nigeria, where collectively more than 160 million people lack access to clean water close to home. It found that groundwater data tends to be limited — including on issues such as overextraction, pollution, and contamination — leaving little evidence for decision-makers to consider for its management.

“There’s a general lack of information and data … which makes it very hard to manage the resource sustainably,” said Vincent Casey, senior water, sanitation, and hygiene manager for waste at WaterAid…(More)”.
