Natural Disasters and Extreme Heat Are Creating a New Global Employment Crisis

Natural disasters are no longer just destroying homes, roads, and infrastructure. They are increasingly wiping out jobs, reducing worker productivity, and slowing economic growth. A new study by researchers from the World Bank, ETH Zurich, and the African Institute for Sustainable Energy and Systems Analysis shows that floods, earthquakes, storms, tsunamis, and extreme heat are causing major employment losses worldwide.

The study is one of the first to measure the impact of natural hazards in terms of full-time job losses rather than only economic damages. The findings offer a new way of understanding how disasters affect people's livelihoods and why protecting jobs should become a central part of climate and disaster policies.

Millions of Jobs Lost Every Year

According to the study, rapid-onset disasters such as floods and earthquakes cause the equivalent of 9.4 million full-time job losses annually across 132 countries. Floods account for the largest share of losses, followed closely by earthquakes.

India and China experience the highest annual job losses, with around 1.2 million job equivalents each year. Myanmar, the Democratic Republic of Congo, Indonesia, Haiti, Bangladesh, and Pakistan are also among the countries most affected.

The researchers note that the impact of rare but severe disasters can be much larger than annual averages suggest. A major flood or earthquake occurring once in a century can result in job losses many times greater than what countries typically experience in a normal year.

Poor Countries and Poor People Pay the Highest Price

One of the study's strongest messages is that natural hazards deepen inequality. While middle-income countries experience the largest number of job losses in absolute terms, low-income countries suffer the greatest losses relative to their workforce size.

Within countries, poorer households consistently bear a larger share of the burden. Families with fewer savings, weaker social protection, and limited access to insurance struggle the most to recover when disasters disrupt livelihoods.

This means that natural hazards are not only environmental challenges but also development challenges. Job losses can push vulnerable families deeper into poverty, reduce spending power, and slow local economic recovery for years after a disaster.

Extreme Heat Is an Even Bigger Threat

The study finds that extreme heat may be causing an even larger employment crisis. Between 2015 and 2024, heat exposure was associated with an average of nearly 80 million job-equivalent losses annually across 114 countries.

Unlike floods or earthquakes, heat affects workers every year by reducing their ability to work safely and productively. Outdoor sectors such as agriculture and construction are especially vulnerable.

South Asia and Sub-Saharan Africa face the highest heat-related job losses, with India recording the largest impact. Workers in poorer countries are particularly exposed because they often lack access to cooling systems, workplace protections, and modern technologies that can reduce heat exposure.

What Policymakers Can Learn

The study carries an important message for governments: disaster resilience is not only about protecting infrastructure but also about protecting jobs and incomes.

For policymakers, the findings provide a practical roadmap. Investments in early warning systems, climate-resilient infrastructure, flood protection, stronger building standards, and climate-smart agriculture can help reduce future job losses. Expanding social protection programs, disaster insurance, and emergency cash support can also help vulnerable households recover faster after shocks.

The research is particularly useful because it translates disaster impacts into employment terms that are easier for decision-makers to understand. Instead of focusing only on billions of dollars in damages, policymakers can see how many jobs and livelihoods are at risk.

As climate change intensifies and extreme weather events become more frequent, the report argues that safeguarding employment should become a key objective of development and climate policies. Protecting workers from disasters and extreme heat will not only reduce poverty but also strengthen economic resilience, productivity, and long-term growth.
