This report explores how integrating nature into built, gray infrastructure systems can help provide services like food, flood protection, and clean water. These green solutions can open new opportunities for financing, and boost resilience to climate change.
Green infrastructure like forests, wetlands and coral reefs can help traditional “gray infrastructure” perform better. Yet, green-gray infrastructure projects remain relatively niche, mainly because of persistent myths about their costs and feasibility.
At this event, the World Bank and WRI will launch a new report, Integrating Green and Gray: Creating Next Generation Infrastructure, which explores how nature can act as infrastructure to help meet development and climate goals.
For the cash-strapped government of Rio de Janeiro, restoring forests around the city is a smart investment. New research shows that forests can provide Rio with better water quality at lower cost.
This summer, California experienced its largest fire in state history—the latest disaster in a growing trend towards hotter, larger, and more destructive fires.
Incorporating natural infrastructure into water management plans can cost-effectively improve infrastructure system performance and resilience.
Today at the Global Climate Action Summit, 45 cities across six continents joined the Cities4Forests initiative, committing to conserve and restore their forests while making residents more aware of the vast benefits of trees.
World Water Week is a unique opportunity for individuals around the world— from experts and decision-makers to young professionals—to discuss the world's most pressing water issues and identify promising solutions. Take a look at WRI's scheduled events.
Green bonds finance sustainable infrastructure projects. A new criteria sets standards for green bonds for built and natural water infrastructure.
Wetlands, forests and other green spaces are the original water infrastructure. For the first time, they can now be financed through bonds – just like other built infrastructure such as treatment plants and dams.
From clean water provision to storm protection, forests provide benefits for everyone—even those who live in the concrete jungle.
Brazil's forests are its historic first line of defense against water stress and water-related natural disasters, but now these forests are under pressure. Will Brazil increase investment in its natural infrastructure to defend against water crises?
