Early Warning System - Rationale

• Early warning systems (EWS) received very high attention during last two decades after some extra-large disasters in the world

• Countries vulnerable to hydro-met disasters have realized the significance of EWS at national and local levels

• Like many other parts of the world, Pakistan is also extremely vulnerable to hydro-meteorological disasters

• In Pakistan, more than 70% hydro-met disasters occur during monsoon season

2

• Very high degree of vulnerability of hydro-met in Pakistan, where necessity tends to force the poor to occupy the most vulnerable areas

• Long history of floods – Pakistan experienced 20 major floods during last 66 years

• Reported financial loss of more than US$ 39 billion

• Trends of repeated hydro-met disasters resulting in high damages led to develop an integrated Effective EWS at national and local levels

The existing system may be transformed into EffectiveEWS, by addressing the following GAPS:

Recommendations

Existing EW system is not appropriate to disseminate theinformation to communities and emergency responders

• Availability of Hydro-met data

• Create awareness in stakeholders & vulnerable

communities

• Improved coordination among nodal organizations

• Effective dissemination system
