Welcome to Our Future Water's newsletter on "Financing Water Security: Bridging the Funding Gap," which explores the funding shortfalls in this sector and presents innovative financing mechanisms that can bridge these gaps. Threatened by chronic underfunding, the sustainable and equitable management of water—essential for life and economic activity—is at risk. Proper water resources management, requiring substantial investments in infrastructure, technology, and conservation practices, is critical for promoting health, well-being, and biodiversity, especially in areas facing water scarcity or quality issues. Underinvestment can exacerbate water scarcity, increase disease risk, degrade water quality, deplete groundwater, and heighten vulnerability to climate change, negatively affecting agricultural productivity, food security, and economic growth opportunities. In this newsletter, we explore innovative financing mechanisms to fill the existing funding gaps in this sector.
