In many parts of the world, water availability is in decline and its quality is deteriorating. According to the World Bank, water scarcity, intensified by climate change, could come at a high price for some regions, costing as much as 6 percent of their gross domestic product. Tackling the water challenge is crucial to unlocking poverty eradication, prosperity, ecosystems preservation, and gender equality. As such, water security is a fundamental element of a sustainable development agenda. The United Nations Sustainable Development Goals recognized this by introducing a dedicated water goal (“SDG 6”) that seeks to “ensure availability and sustainable management of water and sanitation for all.”
