The United Nations World Water Development Report 2018 - Nature based solution for water

More than 2 billion people lack access to safe drinking water and more than double that number lack access to safe sanitation. With a rapidly growing global population, demand for water is expected to increase by nearly one-third by 2050. In the face of accelerated consumption, increasing environmental degradation and the multi-faceted impacts of climate change, we clearly need new ways to manage competing demands on our precious freshwater resources.
The 2018 edition of the UN World Water Development Report (WWDR2018) suggests that solutions may be closer than we think.
