Drought Monitoring and Response

• • • Drought: an increasingly damaging phenomena – Growing population & agricultural stresses on surface & groundwater – Reduced snow and glacier reservoirs Complex phenomena – Defined across many time scales, impacting many economic sectors – Sea surface temperatures (SST), winds, land cover, many other factors Scenario objectives – Monitor & forecast drought indicators – Assess water and drought conditions and impacts – Plan for mitigation – Carry out response strategy – Consider and address multi-disciplinary and cross-border institutional communications and coordination 2

Actors

• • • •

Consumers

– Residential, commercial, industrial, agricultural

Local officials

– City managers, county managers

Agency officials and staff

– State Natural Resource Department decision/policy makers – State and Federal agency water managers – (USA) Army Corps of Engineers

GEOSS portal integrator

Information available before scenario - 1

• •

Example regions of interest

– Near-term: Southeastern USA (NIDIS data and capabilities) – Longer-term: Pacific Basin (Americas, Australia, Pacific Islands)

Framework geographical datasets

– Roadways, landcover, hydrography – Locations of major agricultural production, industrial centers, and urban areas with high water resource demands – Gazetteer and locations for built-up areas, with linked population figures – Digital terrain/elevation model – Orthophotography or satellite imagery 4

Information available before scenario - 2

•

Environmental data

– Precipitation – Soil moisture indices – Drought indicators • Palmer Indices • SPI (standard precipitation index) • VHI (vegetation health index) • SWSI (surface water supply index) – Snow water content and snow depth – Streamflow, lake and reservoir levels, and groundwater status – Soil and air temperature – Humidity – Wind speed and direction – Solar radiation 5

Specific processing capabilities

• • • • • Monthly and seasonal forecasting of temperatures and precipitation; anomalies (greater/lesser than normal) 12 months in advance (example source: NWS Climate Prediction Center) Assessment of current water conditions (precipitation, ground water, USDM indices, water monitor network, many products) Drought 3-month outlook (USDM subjectively derived) Drought impacts monitoring system with impacts database, analysis tools and practices Determination of drought triggers: threshold values of an indicator that distinguish drought magnitude and determine when management actions should begin and end – PDI or USDM triggers result in actions taken by state and local managers; generally locally/regionally determined, not national – In the US, Army Corps of Engineers may respond to triggers 6

GUI development, GEOSS portal integration

• Data discovery tools: portal (GUI) & clearinghouse (harvester) – For community data sources (metadata) to be harvestable, metadata server needs to support CSW – If community data sources support standard WMS, WCS, WFS, SOS, etc. services, the portal can preview and access the actual datasets; otherwise it will simply refer user to remote server – Integration with OPeNDAP should be considered • Data viewer client: within the portal, Google Earth, etc.

• Drought research community “adopts” the portal – Community-managed web UI – wiki, journals, pre-defined and derived maps – Build and save projects; add new data as it emerges – Help support cross-cutting, multi-disciplinary applications 7

Institutional coordination

• WMO, CEOS, IGOS/IGWCO, GCOS, GEWEX • NIDIS (US National Integrated Drought Information System) • NADM, USDM (N.American/US Drought Monitor) • FEWS (Famine Early Warning Sysem) • Drought Management Center of Southeastern Europe • HARON (Hydrological Applications and Run-Off Network) • NCAR (US National Center for Atmospheric Research) • Plus many others as potential collaborators – see National Drought Mitigation Center International Activities 8

Develop a Task within the GEO Work Plan Summer 08: Hawaii) Convene a meeting of technical leadership to identify needs and priorities (Hosted by the IDEA Center in

Prerequisites for demonstration participation

Necessary capacity at national level:

• Current drought monitoring capabilities and practices • Observational data network activities, capabilities, and resources • Drought forecasting • Drought response • Current potential level of participation in global network • What is needed for them to reach their desired level of participation – May have different levels of participation depending on variations in countries’ capabilities and desires 10

Next Steps

• Work with likely participants to identify case studies – NIDIS Portal team working on Southeast US drought response (near term) – Broader drought science community trying to build capacity among developing countries & islands in Pacific Basin to support DEWS (longer term) –

Others…?
