New displacement in 2016
There were 24.2 million new displacements by
disasters brought on by sudden-onset natural
hazards in 118 countries and territories in 2016.
They outnumbered new displacements associated with conflict and violence by more than
three to one. In the nine years since 2008, 227.6
million such displacements have been recorded,
or an average of 25.3 million per year.
The largest events determine much of the variation in global totals from year to year. IDMC
recorded 31 disaster-related displacement events
that each caused at least 100,000 displacements
in 2016, accounting for 86 per cent of the total.
They included five very large events that each
displaced between one and three million people.
Unlike most other years, however, there were
no mega-scale events that triggered more than
three million displacements (see figure 1.13). A
significant percentage of total new displacements in the context of sudden-onset disasters
are usually related to planned or spontaneous
evacuations, many of which present only shortterm displacement occurring in a relatively safe
and orderly manner. However, in the absence of
reliable reporting on returns, it is not currently
possible to clearly determine the numbers, length
and severity of displacement.
IDMC’s global estimates cover disasters triggered
by sudden-onset hydro-meteorological and climatological hazards such as floods, storms, wildfires
and extreme winter conditions; and geophysical
hazards such as earthquakes, volcanic eruptions
and landslides. They do not include displacements associated with slow-onset disasters such
as drought and environmental degradation. Nor
do they cover those associated with technological and biological hazards, such as industrial accidents and epidemics, except when they
are triggered by a natural hazard. The displacement caused by radiation exposure in Fukushima
following the Tohoku earthquake and tsunami in
2011 is one such example.
