Few places have suffered more from the COVID-19 pandemic than southern China, the region where the novel coronavirus was first detected in the city of Wuhan. But it turned out that the pandemic is not the only calamity to befall south China this year. The region has been inundated by heavy rainfall since late May, creating a risk of catastrophic flooding. While southern China typically sees heavy rainfall in the summer months, state media reported that this year’s precipitation has been roughly 20 percent higher than normal. Other outlets report that flooding has affected over 30 million people across dozens of provinces and resulted in over 120 deaths. 

This year, three pandemics have shaken the fabric of our society, said Les Williams, Co-Founder and Chief Revenue Officer at Risk Cooperative at a recent event co-hosted by the Wilson Center and Stanford Woods Institute for the Environment on building greater resilience for U.S national security. The spread of COVID-19 highlighted the vulnerabilities in our healthcare system. The murder of George Floyd became the tipping point in communicating the risk that Black Americans have been facing for more than 400 years. And a number of natural disasters exposed society’s vulnerability to climate change.

Pakistan ranks eighth on the list of countries most affected by extreme weather events (1998–2017 data), according to the 2019 Global Risk Index. With increasing global temperatures, severe weather and water events, like monsoons and droughts, are likely to become even more frequent and extreme in the future. Since the 1960s, Pakistan has observed changes in temperature and precipitation. By the end of the century, Pakistan’s temperatures are expected to be significantly higher than the global average.

For two weeks, Hurricane Dorian, one of the strongest hurricanes to make landfall in the Pacific, decimated large swaths of the Caribbean displacing 70,000 people and killing at least 50. Natural disasters like Hurricane Dorian in the Caribbean have only been worsening over the last decade, a trend often attributed to warming oceanic and atmospheric temperatures.

The Horn of Africa faces critical security and climate risks. Persistent droughts have precipitated the onset of food insecurity and waterborne disease, while heavy rain events such as Cyclone Sagar have caused widespread flooding, mudslides, and wind damage. These challenges are increasing in severity against a backdrop of changing demographic trends—including rapid population growth, increased migration, and urbanization—and power struggles both within and between countries in the region.  

By 2050, the UN estimates that 52 percent of the world’s population will be at risk for water insecurity. Climate change is threatening water availability through increased temperatures and drought, unpredictable rain, and the growing threat of more pollution. Globally, most wastewater reenters the water cycle without being treated, introducing dangerous unseen particles including pharmaceuticals, diseases, and larger waste products such as plastics.
