How can we reduce floods, droughts and water pollution?
By using the solutions we already find in nature.
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 (NBS) to the water challenges we face in the 21st century. The campaign is called ‘The answer is in nature’ and raises awareness of NBS. The central message is that NBS, such as planting trees to replenish forests, reconnecting rivers to floodplains, and restoring wetlands, is a sustainable and cost-effective way to help rebalance the water cycle, mitigate the effects of climate change and improve human health and livelihoods. By using NBS to help meet the water needs of a growing population, we will contribute to the creation of a circular economy, at the same time as helping to protect the natural environment and reduce pollution – both key targets in Sustainable Development Goal 6, which commits the world to ensuring availability and sustainable management of water and sanitation for all by 2030.
