DEWRS Project
Provide near real-time alerts about natural
disasters.
Will integrate the existing emergency response
systems and the environmental monitoring
stations into a national disaster early warning and
response system.
Thursday, 02 August 2012 3
Objectives
Collect data on indicators of disasters.
Use collected data to predict disaster.
Disseminate warnings of impending disasters in a
timely manner.
Provide tools to assist in coordinating response to a
disaster.

Problem Statement
No existing multi-disaster EWS in Namibia.
Need for a mechanism to deliver critical warnings
of impending disaster
Needs to be accurate, easy to maintain and
accessible to non-technical personnel
Thursday, 02 August 2012 5
Major Research Question
How can search algorithms be used to design reliable
low-cost Early Warning Systems?

Limitations
Unavailability of a large historic database
Changing developing environment
Suffered a major setback with .NET Framework
changes on developer’s computer in the weeks
leading up to presentation
Thursday, 02 August 2012 19
Conclusion
DERWS demonstrated a very affordable and viable
approach to developing EWSs
The project re-emphasized the need of integrating
single disaster EWSs into a multiple disaster EWS
Drew attention to how AI can be applied as a set of
fast queries on large databases
Re-enforced the core concept of AI
Simulating learning
Thursday, 02 August 2012 20
Future works
Deploy faster scripts in place of queries
Integrate with broadcasting media for quick alert
dissemination
Web implementation (distributed systems are the
future)
Integrate with satellite weather monitoring systems
to get real time alerts and warning
Build on the DEWRS with a versatile disaster
simulation and response coordination package
