The Hard Landing Ahead – Why Current Disaster Strategies Are Doomed to Fail

Below is the TLDR from my hot take blog about the UN Office for Disaster Risk Reduction Global Platform meeting in Geneva June 2-6.

You can read the full blog by following the link. 

This hot take is Part I of II, and I'll post Part II soon (based on the Accelerator for Systemic Risk Symposium that took place near Paris, June 7-9). 

The UN Global Platform made me think about several strands of research and action which really need to be integrated better in analysis and policy. These are: Disaster Risk Reduction activities, Systemic Risk research and mitigation, Global Stresses driving the 'Polycrisis', and 'Metacrisis' issues underpinning those stresses. Single issue and single hazard actions will not succeed without addressing these drivers collectively.

Thanks for the post, Matt! Strongly upvoted.

Despite the comprehensive Sendai Framework adopted by 187 countries, disaster impacts are actually increasing globally.

I would not be surprised by an increasing total cost from disasters (accounting for mortality, morbidity, and econonic effects), but I think the total cost from disasters as a fraction of the gross world product (GWP) has been decreasing over the past few centuries. I expect the total cost to be roughly proportional to the cost accounting only for effects on mortality, and I estimate the annual conflict deaths as a fraction of the global population decreased 0.121 OOM/century from 1400 to 2000 (coefficient of determination of 8.45 %), and the annual epidemic/pandemic deaths as a fraction of the global population decreased 0.459 OOM/century from 1500 to 2023 (38.5 %).

The annual deaths from natural disasters as a fraction of the global population have also been decreasing since 1900.

Many thanks Vasco, and thanks for the additional data for context too. I think a big chunk of the UN GAR 2025's '$2 trillion' cost impact was attributed to things like ecosystem destruction from droughts. Which that report argued had not been properly costed in previous calculations. I take your point about the fact that death rate from equivalent disasters today vs in the past is lower now (with correspondingly lower monetized harm). Cheers!

Thanks for clarifying, Matt!

I do not know how the cost of ecosystem destruction that went into those 2 T$ was estimated. However, some estimates of costs of that type rely on methods which I believe can easily overestimate the real cost. Some rely on how much people reportedly value biodiversity, which is subject to social desirability bias. Others rely on the cost that would be needed to return the environment to its original state, whereas this cost may be much higher than the damage caused to humans.

In addition, I think ecosystem destruction is beneficial to wild animals, given my best guess that wild animals have negative lives, and I believe the effects on wild animals are way larger than those on humans. I calculate GiveWell’s top charities increase the welfare of soil nematodes, mites, and springtails 87.6 k times as much as they increase the welfare of humans due to increasing agricultural land.
