2018: Extreme weather events affected 60m people

Mami Mizutori, Special Representative of the Secretary-General for Disaster Risk Reduction, said: “No part of the globe was spared from the impact of extreme weather events last year. Examined floods, droughts, storms and wildfires affected 57.3 million people, underlining once more that if we want to reduce disaster losses, then we must improve how we manage disaster risk.

“Time is running out for limiting global warming to 1.5˚C or 2˚C. We have to be equally active about climate change adaptation which means reducing disaster risk in our cities, avoiding the creation of new risk by better land use, stronger planning regulations and building codes, safeguarding protective eco-systems, reducing poverty, and taking active measures to reduce exposure to rising sea levels.”

The 2018 toll of 10,373 lives lost compares with an annual average of 77,144 deaths recorded between 2000 and 2017, averages which are inflated by large-scale loss of life in catastrophic events such as the Indian Ocean tsunami (2004), Cyclone Nargis (2008) and the Haitian earthquake (2010). There were no such mega-disasters in 2018 but loss of life from major natural hazards appears to be on the decline likely due to improving standards of living and better disaster risk management.

Seismic activity including earthquakes, tsunamis and volcanic activity disrupted the lives of 3.4 million people last year and claimed more lives than any other hazard type, including Indonesia (4,417), Guatemala (425) and Papua New Guinea (145).

Floods continued to affect the largest number of people, 35.4 million people, including 23 million people in Kerala, India. They caused 2,859 deaths including India (504), Japan (220), Nigeria (199), and Korea DPR (151).

Storms affected 12.8 million people last year and caused a recorded 1,593 deaths. It is anticipated that storms, particularly due to hurricanes Florence (14 billion USD) and Michael (16 billion USD) and typhoon Jebi (12.5 billion USD), will be the costliest type of disaster of 2018 once final economic losses are compiled.

Wildfires in Europe and North America claimed a record number of lives as Greece (126) had the deadliest European wildfire on record, and the United States (88) had its deadliest wildfire in over a century, and costliest wildfire on record (estimated 16.5 billion USD).

The CRED statistics highlight that 9.3 million people were affected by drought worldwide, including Kenya (3 million), Afghanistan (2.2 million), and Central America (2.5 million), including migration hotspots Guatemala, Honduras, El Salvador and Nicaragua. Insufficient reporting from drought and extreme temperatures events hinder a better understanding of these events worldwide.

Debarati Guha-Sapir, head of CRED at UCLouvain, said: “The impact of all disasters, particularly drought and extreme temperatures are notoriously poorly reported, especially from low-income countries. The human impact of these events, are difficult to quantify, but it needs to be done urgently, especially in order to report on specific SDG target indicators. Therefore, innovative approaches that measure progress in resilience and the adaptive capacity of communities needs to be addressed by appropriate UN agencies.”

UN member States are committed to reducing disaster losses and implementing the Sendai Framework for Disaster Risk Reduction (2015-2030), the global plan for reducing disaster losses which has a clear focus on reducing mortality and the numbers of disaster affected people, as well as reducing associated economic losses and damage to critical infrastructure.
