New analysis shows that approximately 21 million people worldwide could be affected by river floods on average each year, with that number rising to 54 million in 2030 due to climate change and socio-economic development.

The rainforests of Africa’s Congo Basin are the world’s second largest, and are increasingly one of the most threatened. Agriculture, mining, logging, and climate change are already chipping away and thinning out the forests’ edge and interior. The Congo Basin forests’ biggest threat, however, is unseen: a lack of good information. With poor infrastructure, government capacity challenges, and hard-to-detect patterns of change, the forests of the Congo Basin are among the most difficult in the world to monitor and manage.
Starting this month, 1,500 high-resolution satellite images of the Congo Basin from the SPOT satellite constellation provided by Airbus Defence and Space are being shared with WRI, thanks to an agreement with French institutions of the Tropical Forest Spatial Observation program.
WRI’s Aqueduct project recently evaluated, mapped, and scored stresses on water supplies in the 100 river basins with the highest populations, 100 largest river basins, and 180 nations. We found that 18 river basins—flowing through countries with a collective $US 27 trillion in GDP—face “extremely high” levels of baseline water stress. This means that more than 80 percent of the water naturally available to agricultural, domestic, and industrial users is withdrawn annually—leaving businesses, farms, and communities vulnerable to scarcity.
New research from the World Resources Institute scores water-related risks facing 180 countries and 100 river basins. This is the first national-level data of its kind, evaluating competition for available water supplies, annual and seasonal supply variability, flood occurrence, and drought severity.
The data paints a country-level picture of water risks, information that is clearly relevant for national policymakers. But this research also holds huge implications for the private sector—particularly for shareholders and investors, corporate operations, and corporate supply chains. Multinational businesses should take notice—and take action.
