Abstract:
Knowledge of natural hazards is still insufficient in our country, we don’t know the magnitude
of a previous risk, whether flood or earthquake: the last extreme events have taken the
dimensions of catastrophes as floods in Bab El Oued, Ghardaia, El Bayadh and earthquake in
Boumerdes, which resulted in an impressive number of deaths and property damage, which
seriously affected the state budget.
The present situation reflects a lack of experience feedback and that the memory of the effects
of past disasters is not profitable at best to be able to apprehend positively the events to come.
However, the manifestations of natural hazards in Algeria confirm that many cities are directly
exposed to natural hazards, earthquakes, floods, landslides such as the case of the present
research applied to the wilaya of Jijel
The wilaya of Jijel is characterized by a mountainous relief with strong slopes which dominates
in the North a littoral exposed to the coastal risk . The wilaya has experienced disasters that
have marked the landscapes but also the memory of population, such as the 1856 tsunami, the
1928 cyclone, the 1984 floods, the forest fires of 1881 and 1983, and the impact of the advance
of the sea on the urbanized coastline.
in front of this threat, what is the level of management of natural risks by the Authorities?
Risk management practices in the wilaya of Jijel result in insufficient, but also constraints: the
lack of available data, the insufficient of planning and urban planning instruments.
The vulnerability of the territories of the Jijel wilaya to the risks is very high through the
strategic stakes such as the harbours impacted by the effects of the advance of the sea and the
thermoelectric power station, while the dams are exposed to the seismic risk.
Risk management has improved considerably with the implementation of works to protect
against the advance of the sea on the Kotama beach (downtown Jijel), drainage systems to limit
the spread of floods in the plains.
Faced with these risks, what is the behavior of the populations? The survey conducted in the
field will determine the level of perception of the inhabitants and their level of familiarity with
the insurance against the effects of natural disasters (Cat Nat).
