On February 28, 2022, the U.N. Intergovernmental Panel on Climate Change Working Group II released its Sixth Assessment Report: Impacts, Adaptation, and Vulnerability. The writing of this report involved more than 270 scientists who spent the past three years reviewing an extensive body of literature to assess the impact of climate change on human and natural systems and better understand the role of adaptation in alleviating some climate-related impacts.

The International Water Management Institute’s Dr. Aditi Mukherji was one of the coordinating lead authors of the report’s water chapter, which reviews observed and anticipated hydrological shifts, gauges the risks these changes pose to human and natural systems, and explores the potential for water-related climate adaptation measures.

In this webinar, IWMI brings together six of the lead authors who contributed to that chapter to walk you through some of their key findings.


The water chapter reiterates findings from the IPCC Working Group I report about the intensification of the water cycle, and shows how ecosystems and all economic sectors have been affected by climate-induced water cycle intensification. Indeed, the majority of world’s population — especially those involved in climate-sensitive occupations like agriculture — are experiencing impacts of climate change through shifts in the water cycle. Such impacts can assume the form of extreme precipitation, accelerated glacial melt, crippling drought, or severe flooding.

But if water is the primary medium through which people feel the impacts of climate change, it is also a part of the solution. The majority of adaptation options available to us today either exist in response to water-related hazards, or are themselves water-related adaptation measures, such as soil moisture conversation, enhanced rainwater harvesting, improved water storage, and more.
