The Global Risks Landscape, as defined by the survey, highlights five global risks that stand out as both highly likely and highly potentially impactful (upper right quadrant of Figure 1). Interstate conflict has significantly leaped up both dimensions since 2014, arguably reflecting recent geopolitical conflicts that are fuelling geopolitical and social instability. As last year, concerns about environmental and economic risks remain, in particular around failure of climate-change adaptation, water crises1 and unemployment and underemployment reflecting concern about how little tangible action has been taken to address them. At the same time, cyber attacks remain among the most likely high-impact risks.
