Drought Monitoring and Forecasting in the State of Ceará Meiry Sakamoto and Eduardo Martins [email protected] Northeast Drought Monitor Three Pillars of Drought Preparedness 1. Monitoring and forecasting/early warning 2. Vulnerability/ resilience and impact assessment 3. Mitigation and response planning and measures Foundation of a drought plan Identifies who and what is at risk and why Pre-drought programs and actions to reduce risks (short and long-term) Indices/ indicators linked to impacts and action triggers Involves monitoring/ archiving of impacts to improve drought characterization Feeds into the development/ delivery of information and decisionsupport tools Well-defined and negotiated operational response plan for when a drought hits Safety net and social programs, research and extension STATE MET SERVICES/ EMATERS Northeast Drought Monitor INTEGRATION OF DATA BANK METEOROLOGY ANA CEMADEN CPTEC INMET • • • • • STATE MET SERVICES 5 categories of drought Initial frequency: monthly Integration of data: meteorological, hydrological and agricultural Participatory and collaborative tool Local validation MAPA INMET/ CONAB+CEMAD EN AGRICULTURE INTEGRATION OF DATA BANK Drought Monitoring and Forecasting in the State of Ceará Meiry Sakamoto and Eduardo Martins [email protected] ANA CEMADEN WATER RESOURCES CPTEC STATE WATER AGENCIES INTEGRATION OF DATA BANK 15 Drought Monitoring and Forecasting in the State of Ceará Meiry Sakamoto and Eduardo Martins [email protected] Main Indicators (12, 4 and 3 months): • SPEI (Standardized Precipitation • Evapotranspiration Index) SPI (Standardized Precipitation Index) Map generated with SPEI12+ SPI12 + SPEI 3 and 4 + SPI 3 and 4 Northeast Drought Monitor 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 + impact indicators Drought Monitoring and Forecasting in the State of Ceará Meiry Sakamoto and Eduardo Martins [email protected] Northeast Drought Monitor Planning for drought preparedness and how public policy actions and contingency are triggered by the categories indicated in the Monitor Normal or wet conditions - Constant monitoring and forecasting - Implement long-term mitigation actions outlined in the drought plan (e.g., infrastructure and research) Entering drought - 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 Immersed in extreme 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 Normal or wet conditions - Back to emphasizing monitoring and forecasting and implementing long-term structural activities in the drought plan International Expert Symposium “Coping with Droughts” Building a Community of Practice on Drough Management Tools 19th – 21 th November 2014, Santiago, Chile Thank you!
