The Context

Monthly average rainfall and rainfall distribution (January‐December) forCeará from 2007 to 2017. Wet years are depicted in blue, dry years inred, and the average reference year is located at the right of the figure.

Drought Monitoring1. Data integration effort from current meteorological and hydrological

observation networks (state and federal) throughout the Northeast

Region.

2. Collaboration with national and international institutions in order to use

satellite‐based indicators to monitor drought and its impacts.

3. Use of hydrological semi‐distributed models to derive hydrological

drought indicators throughout the region (ongoing activity).

4. Introduction of new drought indices that are not currently used, but are

currently on test, in order to be included as part of a Drought Information

System (ongoing activity).

5. Expand the network of observers to gather impact information from the

water and agriculture sectors (ongoing activity).

Hydrological Drought

Drought Prediction and Early Warnings 1. SSTs forecast system from IRI, now @FUNCEME July/2017.

2. Scenario building based on current conditions

3. Climate forecast system combining different global/regional

models:

Global: ECHAM 4.6 (@FUNCEME), NMME, CPTEC

Brazil: INMET Statistical Model

Regional Models: RSM97/2008, RAMS

4. Forecasting Drought Indicators: SPI, SPEI, SRunnoff, SDSI (Dry

Spell)

5. Other Forecasting Products: Inflows to the main reservoirs of the

region Effective use in the Water Allocation of 12 basins.

Drought Impacts and Risk Assessment 

Initial talks on implemmenting vulnerability assessment studies in

order to determine who and what is at risk and why.

State network of observers to gather and report information about

ongoing impacts of droughts.

Mitigation and Response

Develop system‐ and sector‐specific contigency plans ‐ e.g. each water

supply system will have its contigency plan, establishing what

mitigation actions should be undertaken according with the triggers

and the decision calendar related to that particular system.

GLOBAL/NATIONAL vs LOCAL INFORMATION PROVIDERSGLOBAL/NATIONAL vs LOCAL INFORMATION PROVIDERS

Cooperation is a two‐way street: It should not mean data‐sharing only;

What is in for the local/regional institutions? Ultimately, these institutions are the ones that will be hold responsiblefor the provided information.

COOPERATION WITH LOCAL INSTITUCIONALS:  Data sharing Capacity Building Pilots

and as a result  Sustainable local capacity!

Examples in Northeast: IRI, NDMC/CONAGUA.
