Northeast Drought Monitor Drought Monitoring and Forecasting in the State of Ceará Meiry Sakamoto and Eduardo Martins [email protected]
Crisis management treats the symptoms, not the causes.
proactive
reactive
Risk management increases coping capacity, builds resilience.
1. Monitoring and forecasting/early
warning
2. Vulnerability/ resilience and impact
assessment
3. Mitigation and response planning and
measures
Foundation of a drought plan Indices/ indicators linked to impacts and action triggers Feeds into the development/ delivery of information and decision-support tools
Identifies who and what is at risk and why Involves monitoring/ archiving of impacts to improve drought characterization
Three Pillars of Drought Preparedness
Northeast Drought Monitor Drought Monitoring and Forecasting in the State of Ceará Meiry Sakamoto and Eduardo Martins [email protected]
Pre-drought programs and actions to reduce risks (short and long-term) Well-defined and negotiated operational response plan for when a drought hits Safety net and social programs, research and extension

• 5 categories of drought
• Initial frequency: monthly
• Integration of data:
meteorological, hydrological and
agricultural
• Participatory and collaborative
tool
• Local validation

Main Indicators (12, 4 and 3 months):
• SPEI (Standardized Precipitation
Evapotranspiration Index)
• SPI (Standardized Precipitation Index)
Information to support decision:
•Soil moisture (Calculated Soil Moisture
Ranking Percentile – Monthly CPC/NOAA)
•Vegetation Index (Vegetation Health Index –
VHA – NESDIS/NOAA)
•Precipitation (accumulated and anomaly)
Map generated with
SPEI12+ SPI12 +
SPEI 3 and 4 + SPI 3 and 4
Map generated with SPEI12+
SPI12 + SPEI 3 and 4 + SPI 3
and 4 + impact indicators
- Constant monitoring and forecasting
- Implement long-term mitigation actions outlined in the drought plan (e.g., infrastructure and research)
Normal or wet conditions
- Implement short-term mitigation actions; indicators have associated triggers that link with Drought Monitor categories to spur actions in vulnerable sectors pre-defined in the drought plan
Entering drought
- Implement emergency response actions; indicators have associated triggers that link with Drought Monitor categories to spur actions in vulnerable sectors pre-defined in the drought plan
Immersed in extreme drought
- Back to emphasizing monitoring and forecasting and implementing long-term structural activities in the drought plan
Normal or wet conditions
Planning for drought preparedness and how public policy
actions and contingency are triggered by the categories
indicated in the Monitor
