📋 Global Hazard Trends: The Numbers You Need
Knowing global trend data allows you to make evidence-based arguments in longer exam answers. These figures are from EM-DAT (the international disaster database) and UNDRR reports.
Disaster Frequency and Impacts (1970s–2010s)
| Decade | Recorded Disaster Events | Deaths | Economic Losses |
|---|---|---|---|
| 1970s | ~1,000 | ~2 million | ~$550 billion (2011 prices) |
| 1990s | ~2,700 | ~890,000 | ~$1.2 trillion |
| 2000s–2010s | ~3,500 | ~700,000 | ~$2.4 trillion |
The Three Trends (and Their Explanations)
| Trend | Pattern | Explanation |
|---|---|---|
| Disaster frequency | Increasing — roughly trebled since the 1970s | Climate change is producing more intense storms, floods, and droughts. But also: better reporting — disasters that would once have gone unrecorded are now captured by satellite and digital news networks. |
| Death tolls | Generally falling in HICs; remaining high in LICs | Better early warning systems, improved building standards, and stronger emergency services in wealthier countries have dramatically reduced mortality. But 90% of disaster deaths still occur in LICs. |
| Economic losses | Rising steeply | More valuable infrastructure is being built in hazard zones as cities grow. Higher-income countries suffer higher absolute economic losses — but recover faster. LICs lose a much higher proportion of their GDP, slowing development for decades. |
