World Water Day 2022: Groundwater


World Water Day, on 22 March every year, is about focusing attention on the importance of water. This year’s theme  ‘groundwater’, draws attention to the hidden water resource that has always been critically important but not fully recognized in sustainable development policymaking.

Under the title ‘Groundwater - Making the invisible visible’, this year’s campaign will explain groundwater’s vital role in water and sanitation systems, agriculture, industry, ecosystems and climate change adaptation.

The overarching message of the campaign is that exploring, protecting and sustainably using groundwater will be central to surviving and adapting to climate change and meeting the needs of a growing population.
