Floods occur every year in many parts of the world claiming human lives
and causing property damages on a large scale. Although continuous and steady
efforts have been made to reduce flood disasters, statistics of flood disasters
seem to point to an upward tendency contrary to our expectations. IFNet, bearing
the task of flood disaster reduction through network activities, presents these
recommendations as a summary of the 2nd General Meeting of IFNet held on 19 Jan. 2005 in conjunction with UN WCDR
in Kobe.
I. Flood Disasters
1. Situation in Recent Years
The scale and extent of flood disasters depends
upon not only the magnitude of flood as a natural phenomena but also upon the interactions
with various social factors such as the urban structurefs vulnerability to
flood inundation, the related regionfs capabilities to tackle floods and
residentfs ability to react to flooding. In recent years socio-economic
development and diverse ways of life have been growing, which means that once a
flood has caused damages in some areas, it will take a time and a large amount
of energy for them to restore their previous levels of socio-economic
activities.
2. Factors of Increasing Flood Disasters
Globally
increasing flood disasters are mainly attributed to the advance of urbanization
into flood-prone areas. As urbanization has been promoted by development
pressures accompanying economic growth and the inflow of population into urban
areas caused by unemployment and poverty problems in rural areas, solving these
problems cannot expect to be handled by river authorities and disaster
prevention agencies alone.
3. Inadequate Recognition of Risk
Prevention of human losses linked to
water-induced disasters such as floods, tsunamis and debris flows is possible
if adequate actions based on correct judgment of disaster information are taken
before the likely disaster materializes. This is a sharp contrast to the case
of earthquakes which are less predictable and occur momentarily. However proper actions have seldom been taken
in the past against unprecedented natural phenomena. This is because people
tend, in such occasions, to fail to be fully aware of the extent of the danger
and their destroying power even at the moment they are most likely to be
involved in big disasters.
II. Countermeasures to be Promoted
Towards flood disaster reduction, flood issues should be addressed as global ones rather than locally limited ones. Promotions of the following countermeasures are recommended with various initiatives and activities that have been developed in many parts of the world being further coordinated. These will help with global efforts in reducing by
half the number victims due to floods by 2015.
1. Disaster Information for People in
Dangerous Areas
Given that
even those areas which are far from regions having heavy rainfall, domestic or
sometimes cross-border, would suffer from flooding of big rivers, disaster
prevention information which is transmitted extensively bears a great
significance. Such cases occur often, however, where inadequate information
transmission failed to convey important disaster information properly. For
reducing human loss in a short time, it will be efficient to improve and
reinforce the current information transmission systems, leaving no zones
uninformed.
2. Disaster Information Leading to Peoplefs
Evacuation from Dangerous Areas
Disaster information doesnft necessarily lead to prompt evacuation in those
areas without any experiences of past disasters or with relief generated by completed
structural measures. The way of providing information leading to prompt
evacuation in dangerous areas should be examined.
3. Normal Time Efforts Leading to Peoplefs
Evacuation in Emergency
To
ensure that disaster prevention information fully leads to evacuation actions
in emergencies including the assistance to those weak in disasters, it is
essential that true understanding of disaster information and full recognition
of the actions to be taken in dangerous areas are shared among societies in normal
times. Such measures as flood risk analysis, flood hazard mapping, training for
disaster information transmission and actions to be taken, etc. should be
further promoted.
4. Approaches from Whole Society
Since flood disasters are increasing as a result of various
socio-economic factors, itfs difficult to solve the problems without suitable
approach to the primary causes of disorderly urbanization, poverty and so on.
Therefore under the suitable share of roles from national to community levels,
approaches from whole society to raise resilience against floods are requisite.
5. Optimum Combination of Hard and Soft
Measures
In response to individual regional conditions, the optimum combination
of soft and cost-beneficial hard measures should be steadily developed with a
full support from the local communities so that they could have a maximum
effect on disaster reduction.
