World Water Day 2018 – Nature for Water

World Water Day, on 22 March every year, is about focusing attention on the importance of water. This year’s theme, ‘Nature for Water’, explores nature-based solutions to the water challenges we face in 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 clean 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.
