WORLD Water Day was celebrated on 22 March.

There are over 663 million people living without a safe water supply close to home, spending countless hours queuing or trekking to distant sources, and coping with the health impacts of using contaminated water.

This year’s theme explores how we can use nature to overcome the water challenges of the 21st century.

Environmental damage, together with climate change, is driving the water-related crises we see around the world. Floods, drought and water pollution are all made worse by degraded vegetation, soil, rivers and lakes.

When we neglect our ecosystems, we make it harder to provide everyone with the water we need to survive and thrive.

Nature-based solutions have the potential to solve many of our water challenges. We need to do so much more with ‘green’ infrastructure and harmonize it with ‘grey’ infrastructure wherever possible. Planting new forests, reconnecting rivers to floodplains, and restoring wetlands will rebalance the water cycle and improve human health and livelihoods.
