The Natural Infrastructure for Aquifer Recharge Financial Calculator, is an excel based tool with a flexible financial model that estimates the private costs and benefits, including the return on investment (ROI), of natural infrastructure interventions designed to enhance aquifer recharge. The technical note explains the methods, data and assumptions used to produce the tool.
Organized by the Stockholm International Water Institute (SIWI), 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.
New research finds millions have access only a few hours a day, while others are forced to pay up to a quarter of monthly household income for private provision.
Nearly half the population in 15 major cities in the global south lacks access to public piped water systems, with access lowest in sub-Saharan Africa and South Asia. For these households without public piped water, water from other sources is either too expensive or unsafe.
New data on WRI's Aqueduct platform ranks the world's countries from least to most water-stressed.
This paper discusses updates to the Aqueduct™ 3.0 water risk framework, that is used, among other things, as underlying database for the Aqueduct Water Risk Atlas and Country Rankings.
Chennai's four main reservoirs are virtually dry. This crisis is not only due to last year's poor monsoon season—lack of proper management is driving the city's water security problems.
The release of a nearly $7 billion bond, which will help the Netherlands adapt to sea level rise, was met with widespread enthusiasm from investors. It's the latest in a wave of innovations in green bonds and climate adaptation.
While the average person drinks 2 to 4 liters of water a day, it requires an astonishing 2,000 to 5,000 liters of water to produce the food that the average person eats each day! Here are five ways companies, farmers and consumers can lessen the food system’s impact on water.
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.
Can we use vast amounts of data, machine learning, and other technologies to warn communities about the risk of water stress driving conflict?
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.
Despite a surge of regulation, single-use plastics continue to make their way into the environment. Here are five reasons why.
More than 700 coastal areas are affected by algal growth and dead zones, despite a growing number of global agreements to reduce water pollution.
Water quality trading can spur more cost-effective reductions of pollution. But they're most effective when they have a strong driver, like a cap, and the new memo isn't as instructive as it could be on that front.
The Global Partnership on Nutrient Management and WRI showcase a new resource for sustainable nutrient management. The Global Nutrient Management Toolbox was designed to help decision makers from local to global, across agriculture, urban, wastewater and energy sectors, take action to better manage nutrients and reduce harm to the environment.
WRI Water Program Director Betsy Otto argues the world needs to make water security a top priority and outlines three key steps we can take, taking a global perspective with examples from the United States and Ethiopia.
Using a social cost accounting (SCA) methodology, this research estimates the market and non-market costs associated with the delivery of urban water, sanitation, transport and energy services in 4 case study cities.
