Some important lessons learned Implement the Early Warning System Organize the population is required to improve the emergency management. Strengthen the capacity of local Civil Defense teams. Creation of a specialized programme for Risk Prevention and Reduction Disaster Risk Management Specialists are necesary.
Conclusions During January 2010, heavy rainfall and flooding across the Cusco region caused very strong socioeconomic impacts. The positive anomaly of precipitation exceeded the 100% in some places. The total losses were more than US $250 million and the most affected sector was infrastructure. It is necessary to accelerate the process of improving risk management which concerns to specialized organisms, government and population.
