Resumen:
Drought connects meteorological phenomena and society in such a way that their
occurrence, almost always, implies negative social and economic consequences. It is a
natural phenomenon common in the Brazilian northeastern Semiarid. Its management
should focus on proactive measures taken before and during the occurrence of droughts.
Water infrastructure constructions may help in this management as they contribute to
decrease vulnerability and consequently reduce drought impacts. Monitoring is another
fundamental tool in this process because it can integrate warning systems and guide the
right time to perform preparedness and mitigation actions. Different drought index are
used in monitoring, and should look not only the meteorological phenomena, but also
the significant economic activities for the region. Based on the concept of risk
management, this work sought to identify the relationships between risk management
and the reduction of vulnerabilities to drought, considering that infrastructure works and
drought indexes related to regional economic activities are important keys to this
process. As a result, we can mention that water infrastructure constructions contributed
to the increase in the water supply in the region, which was reflected in the low
vulnerability to drought in the municipalities most served by the program. And that the
drought index VCI, VHI and SPEI have potential for monitoring and management
drought in the semiarid region, which has livestock as its main economic activity.
