The UN Office for Disaster Risk Reduction recently released the fifth edition of the Global Assessment Report on Disaster Risk Reduction (GAR19). The report highlights the increasingly complex interaction between hazards, and provides an update on how risk and risk reduction are understood in practice. GAR19 also highlights how the latest Disaster Risk Reduction (DRR) framework integrates into global goals such as the Paris Agreement and the 2030 Agenda for Sustainable Development. To better understand the scope and significance of this report, New Security Beat sat down with Roger Pulwarty, Senior Scientist at NOAA, and a lead author of the GAR19.

Houston after another major flood a few weeks ago; the Bahamas after Dorian; Paradise, California, after the Camp Fire; Haiti after a major 2010 earthquake; Puerto Rico after Maria; New Jersey and New York after Sandy; New Orleans after Katrina; Thailand and Indonesia after the Indian Ocean tsunami in 2004… The list goes on. As we head into another hurricane season, we should once again examine what we’ve learned and prepare to reduce the impact of disasters on communities worldwide.

Water is so scarce these days in Murrurundi, a drought-tested town in the northern reaches of New South Wales, that it arrives by truck.

Murrurundi Dam, an off-channel reservoir that draws from the Pages River, is functionally dry. An emergency well provides a little local water, but half of the small community’s supply is now trucked in.

“I’ve never seen the Pages River this low,” Daele Healy, who has lived in town for 15 years, told Circle of Blue. “There’s just no water visible at all. Not even little ponds.”

What do we (think we) know about the links between climate change and armed conflict? Early attempts to theorize what climate-related conflict might look like were exceptionally successful in sparking policymaker interest in and funding of research on climate-conflict links. But they were more like works of science fiction than science. Since then, research on climate-conflict links has exploded, with hundreds of articles and working papers published on the subject. Moreover, the findings have been all over the map, with some arguing for strong impacts of climate on conflict at multiple temporal and spatial scales, while others argue—in both specific instances, about the supposedly climate-fueled Syrian Civil War, and more generally—that climate-conflict links are overstated.

In 2018, floods resulted in over 20 casualties and billions of yuan in damage in China, with the government issuing 835 flood warnings nationwide. As global temperatures rise, the combination of extreme weather events and sea level rise threaten the basic infrastructure and water security of low-elevation Chinese cities. Coastal residents account for 43% of China’s population – approximately 170 million citizens live less than ten meters above sea level. In fact, seven of China’s ten largest cities are on the coast, creating high stakes for the government to address impending threats of flooding and sea level rise. Shanghai, China’s largest city, is on the frontlines of climate change as one of the world’s most flood-vulnerable major cities. Shanghai’s government was eager to invest in the sponge city initiative and expand greenspace, rooftop gardens and porous pavements to control stormwater floods. However, officials have been hesitant to invest in climate adaptation measures that don’t create a big splash, like the unglamorous networks of sewage and wastewater infrastructure.

How do we plan for disasters that have never occurred before? One million species are at risk of extinction in the near future from environmental changes. The frequency of historic tropical storms is increasing. The rapidly melting permafrost in the Arctic is placing unprecedented pressures on northern infrastructure. Given the overwhelming and unpredictable nature of new disaster risks, it is not clear what the appropriate responses should be. Our book, Disaster Security: Using Military and Intelligence Planning for Energy and Environmental Risks, addresses how to assess unique environmental hazards and disaster risks, based on tools used by the U.S. intelligence and military communities. The book draws on lessons learned from developing, applying, and translating scenarios and simulations (or wargames) to plan for future environmental security risks.

“When states face fragility and climate risks simultaneously, the risks and challenges are compounded,” according to The Intersection of Global Fragility and Climate Risks, a new global report commissioned by USAID, which was presented during a recent USAID Adaptation Community Meeting webcast. States facing major climate hazards, such as flooding, drought, and sea level rise, will be forced to contend with the cost of humanitarian and adaptation responses to mitigate the physical and livelihood risks threatening their populations. Fragile states struggling with issues of legitimacy in the social, economic, political, and security spheres may become overwhelmed by the process and cost of redirecting limited resources to address climate-induced disasters.  

On 25 January 2019, the UN Security Council held an open debate to discuss the security implications of climate-related disaster events. The meeting, initiated by the Dominican Republic, underscored the global nature of climate-related disasters. Most speakers highlighted the need for better climate risk management as an important contribution to safeguarding international peace and security. The debate marks the beginning of a year in which climate security ranks high on the UN’s agenda.
