A new World Bank Group policy research working paper, “Counting People Exposed to, Vulnerable to, or at High Risk From Climate Shocks“, highlights the growing global impact of extreme weather events, including people’s water-related vulnerabilities.
Over 4.5 billion people, more than half the global population, face high risks from extreme weather such as floods and droughts, with 2.3 billion living in poverty. Access to water services emerges as a critical factor for vulnerability, as households without reliable water sources are less able to cope with these shocks.
The study identifies Sub-Saharan Africa as particularly affected, where high-risk populations have risen between 2010 and 2019. Hazard, exposure, and vulnerability —key factors determining the impact — are compounded by inadequate water access, poverty, and lack of social protections.
Given the large number of people exposed to extreme weather events – and the large share of them who are poor or highly vulnerable – countries need to act urgently to mitigate the impacts of climate change and help people adapt to these risks and protect their welfare.
