A new Green Infrastructure (GI) guide, launched at World Water Week, is set to raise much needed awareness of the benefits of GI solutions for water resources management, says the UNEP. The Green Infrastructure Guide for Water Management: Ecosystem-based Management Approaches for Water-Related Infrastructure Projects is a product of the UNEP-DHI Partnership - Centre on Water and Environment, International Union for Conservation of Nature, The Nature Conservancy and the World Resources Institute, and responds to the increasing recognition that GI represents an important opportunity to address the complex challenges of water management. The publication makes clear that increased efforts to work with GI solutions in water management can result in viable and cost-effective alternatives to grey water infrastructure, as well as support goals across multiple policy areas, including adaptation to climate change.
