ESA Earth Observation
Contribution of Satellite Earth Observation Technology to Disaster Risk Management

Geo-information services versus market segment - market “hot spots” for EO products & services. (Review of the European and Canadian EO sector, 152 product declarations made by 75 different companies).
Planning within post-crisis reconstruction projects(activities in post-crisis context)
Based on these issues how can EO contribute?
ESA’s understanding of DRR activities:
Slide 5
The international community, including the UN and EU systems, has undertaken a variety of initiatives on monitoring hazards, populations, and prevailing environmental conditions, to assist the most vulnerable nations to devise appropriate prevention and mitigation measures prior to such emergencies.
This includes the World Bank/ISDR Global Facility for Disaster Reduction and Recovery (GFDRR) launched in 2006.
Policy instruments & strategic guidelines: the UN Hyogo Framework for Action explicitly cites the need for satellite based applications and geo-information as important tools for disaster reduction (assess & minotor risks, strengthen preparedness).
Strong requirement expressed by African users during the Lisbon GMES Workshop on Security (dec 07): improve access to EO to support disaster reduction
Institutional Framework:
Role of EO based geo-information:
Underlying EO methods for disaster risk reductionhave already been developped, in addition :
new services needed to move from reactivescenarios to more anticipative & systematic EO approaches (e.g. flood defense)
techniques need to be applied to specific local risks and to include in-country training of local personnel (c.f. Matagalpa CIGMAT project)

Slide 6
The use of geo-information today only represents a small fraction of the activities of the DRR sector:
Evidently geo-information (and EO) is not the first & only solution in risk reduction projects
Disaster management users (civil protections, UN, aid workers) have limited time to spend on technology if it is not directly useful & operational within their working environment
Authorised Users: Disaster management centres
Slide 9
Initiated in 2000 by CNES and ESA, joined by CSA, NOAA, ISRO, CONAE, JAXA, USGS, BNSC/DMCii, CNSA, ROSCOSMOS, INPE, DLR & KARI (14 members currently)
Unified system of space data acquisition / delivery in case of natural or human-made disasters (at no cost, best effort basis)
Data delivery to civil protection agencies, emergency & rescue services; UN cooperating body since 2003
Operational : 24 hrs on-duty-operator
Charter activations increasing (50 most important events per year)
Over 9+ years the Charter has delivered data for emergencies in 80+ countries in response to main disaster types. AOIs of User requests for 220+ activations are represented as light pink cells.
Distribution of disaster risk: mortality (Columbia University)
« There are 2 types of disasters, floods and other disasters »
Charter Activations : Hazard Type
Charter activations, volume & trend: Charter events are a Charter activations, volume & trend: Charter events are a limited part of major disasters but activity is increasinglimited part of major disasters but activity is increasing
The curve at the top represents the Charter activations, the one just below represents those that alsoare counted as mass disasters in the world-wide database of CRED (yearly 50 most important events recorded in the EM-DAT database)
The International Charter Space & Major Disasters was triggered by thJapan Cabinet Office less than one hour after the earthquake impact.
JAPAN Earthquake & Tsunami, 11 March 2011
• continuous access to EO data from a wide range of sensors tasked in emergency to supply crisis imagery
• different organisations collaborate on an international basis to provide Value Adding analysis: JAXA in Japan, AIT in Thailand, DLR ZKI in Germany, SERTIT in France and UNITAR/UNOSAT in Geneva.
• French Civil Protection COGIC also has invoked the Charter in the frame of the assistance they provide to Japan with relief teams sent to the field.
• activation extended to address the nuclear accidents consecutive to the EQ & Tsunami

Examples of imagery supplied by ESA via the International Charter; repeat ENVISAT observations are supplied in Near Real Time (2 hoursafter downlink) to US authorities [NOAA & Coast Guards]
Utility assessment by users:
Charter Activations : TimelinessCharter Activations : Timeliness
Total time of an event:
• 7.8 days (2000-2005, 72 cases)
• 8.2 days (2008)

- support Geohazards scientific & operational users for the study of hazards in geologically active regions (earthquake, volcano or other)
- access to space-borne and in-situ geophysical data of selected sites
- initiated from the "Frascati declaration" at the conclusion of the 3rd International Geohazards workshop of the Group of Earth Observation (GEO) held in November 2007 in Frascati, Italy.
