WTW (NASDAQ: WTW), a leading global advisory, broking, and solutions company, announced today a new scientific partnership with Cornell University to quantify the risks of severe and sustained drought worldwide. This collaboration will provide an in-depth view of global exposure to drought risks and the potential effects of water shortages on business operations.

Around two-thirds of the global population live in places that encounter water stress for at least part of the year. When water supplies are further diminished by drought, many communities experience reduced agricultural yield, energy production, and slower economic growth. The adverse effects of drought are more serious in low-income and middle-income countries and are particularly disruptive to agriculture-dominated areas of the developing world.

Climate change has already increased drought risks in many regions, but unfortunately even the latest generation of climate models still underestimate the potential severity, duration, and correlation of future droughts. Under this new initiative, WTW and Cornell University will collaborate to identify geographical ‘hotspots’ for climate-amplified drought, produce more accurate estimates of drought risk, and create new tools and datasets to anticipate single and multi-year drought. At Cornell, the research is supported by the Atkinson Center for Sustainability and led by Prof. Toby Ault, a leading global expert in future drought under climate change.

Scott St. George, Head of Weather & Climate Research for the WTW Research Network, said, “Water is essential to all industries, so no one can afford to have drought take them by surprise. We know climate change has already supercharged droughts in some places — witness the ongoing drought in the American Southwest, now in its third decade. Prof. Ault and his team at Cornell will provide us with a clear view of the real risk of drought and water scarcity. Those insights are absolutely critical for our clients’ operations and planning in water-dependent sectors such as food and beverage, energy producers, and waterborne transport.”

"We're excited to work with WTW to translate cutting-edge climate science into actionable insights for the insurance industry," said Prof. Toby Ault, Associate Professor in the Department of Earth and Atmospheric Sciences at Cornell University. "Our research has shown that traditional climate models often underestimate the risk of severe, prolonged droughts, particularly in regions already facing water stress. By combining our expertise in drought modeling with WTW's industry knowledge, we can better prepare for the complex drought risks of the future."
