Papua New Guinea is vulnerable to several hazards, including floods, droughts, earthquakes, volcanic activity, tsunamis, and sea-level rise. Some of these are expected to increase in frequency, magnitude, and intensity due to climate change. The El Niño Southern Oscillation (ENSO) phenomenon has already been observed to have an increasingly negative effect on PNG’s climate, triggering more intense drought and flood events.
This section provides a summary of key natural hazards and their associated socioeconomic impacts in a given country. And it allows quick evaluation of most vulnerable areas through the spatial comparison of natural hazard data with development data, thereby identifying exposed livelihoods and natural systems.
