Introduction
Unplanned Settlements
The global experience Increased
occurrences in natural disasters
Significant Damage in billions of dollars
The Challenge is therefore to predict,
forecast and manage hazards to reduce
threat to life and property
Communication is therefore essential to
the process of risk reduction
3
DEFINITION
Communication the process of
sharing information a form of social
interaction where at least two
interacting agents share a common set
of signs and language.
In a simplistic form information is sent
from a sender or encoder to a receiver
or decoder.
4
DEFINITIONS
Communication:
"Any act by which one person gives to or
receives from another person information
about that person's needs, desires,
perceptions, knowledge, or affective states.
Communication may be intentional or
unintentional, may involve conventional or
unconventional signals, may take linguistic or
nonlinguistic forms, and may occur through
spoken or other modes."

Importance of Communication
In Disaster Management?
Raises awareness of the hazards
Provides a means of alert and early warning
To take preventive measures to avert
disasters
Provides data for:
integration and analysis of spatial and temporal
disaster data
modeling and simulation disasters more precisely.
Allows for real-time decision making and
enhance emergency response capabilities.
8
Importance of Communication
In Disaster Management?
Allows for vulnerable population and
disaster management persons to be
aware of the details of their
vulnerability
Allows for mitigation decisions to be
made
Builds support for programmes and
activities which support mitigation
9
Importance of Communication
In Disaster Management?
Allows for planners to have an in depth
understanding of vulnerable population,
vulnerable areas, hazards and sectors
at risk
Allows for appropriate planning
measures to be put in place

FLOOD-THREAT RECOGNITION
The goal of the flood-threat recognition system is to enable
early identification, location, and degree of potential flood
situations. The system consists of activities and
arrangements, of which the primary elements are:
Monitoring
•Observation and recording
•Data transmission
•Data assembly and display
Forecasting
•Data processing and analysis
•Forecast preparation
•Validation and updates
12
WARNING DISSEMINATION
Warning dissemination is the mechanism by which local
officials and the effected public are informed that a
flood threat condition exists.
Warning methods may include:
audio alarms,
beeper systems to call key officials,
the use of public radio and television
Door- to-door warning
sirens and public address systems.

ODPEM and ICT
ODPEM currently utilizes a myriad of
systems to aid communication.
Use dates back to the early 1980’s
Built on rudimentary methods and
systems previously employed by the
community
17
TYPES OF COMMUNICATION TOOLS
USED AT ODPEM
18
Communication Tools Utilized at
ODPEM
•Electronic Message Handling
System (EMHS)
19
Other ICT’s currently in use
Sensors
GIS
20
GIS
GIS
allows you to spatially represent
areas at risk and the level of Risk
associated with a particular Hazard.
This
in turn guides decision making
as to possible Mitigation measures
21
What are sensors?
Physical device (most are electrical)
that detects a signal suggesting a
change in the normal state
Links directly/indirectly through a
computer, so that the value sensed
becomes human readable;

BACKGROUND
RIO COBRE
Floods of June 1986 cost the country J$415
mil. In losses
Prompted the implementation of a flood
damage reduction programme:
Flood Plain Mapping
Improvement of flood control methods
Development of Community Flood Warning
Systems Island wide
Installation of Automatic Flood Warning Systems
Flood Hazard Maps
25
BACKGROUND
RIO COBRE
Project developed to improve accuracy
and reliability of predictions for flooding
Using advanced hydrologic and
meteorological automated Flood
Warning System
Public Awareness Programmes
Training in communications, warnings
and evacuation procedures
26
BACKGROUND
RIO COBRE
The system collects rainfall and stream flow
data at sites in the upper watershed.
Information transferred electronically to a
base station.
Alarm system would be used if levels were
exceeded.
Locating the gauges allowed for lead time in
evacuation.
Stations would be manned 24 hours.
27
BACKGROUND
Cave River
Initiated due to recurrent and extensive
flooding since 1900
Program implemented in two parts – 1982
and 1986
The project was seen as a pilot project
that if successful could be implemented in
other such affected communities.
28
BACKGROUND
Cave River
A total of 21 caves and sinkholes between Cave
Valley to Aenon Town
12 of which exist in Aenon Town alone
Town is a part of well interconnected sinkhole
system, controlled by faults and fractures
Caves and sinkholes have a high capacity for
receiving flood waters
29
BACKGROUND
