  1. Coastal GTOS: Priorities, Status and Potential Directions Robert R. Christian East Carolina University December 2009

  2. Outline • Context for CGTOS • Priorities • Accomplishments, status, connections and potential directions

  3. Coastal Observing Systems • The UN Coast • C-GOOS (COOP) • C-GTOS • Coral Reef programs GCOS Atmosphere IGOS Coastal Theme GTOS GOOS Other activities Land and freshwater Oceans and coastal seas GEO Coastal Zone Community of Practice

  4. Primary Goal of Coastal GTOS To detect, assess and predict global and large-scale regional change associated with land-based, wetland and freshwater (and when appropriate transitional waters) ecosystems along coasts. Strategic design and phase 1 implementation plan http://www.fao.org/gtos/pubs.html

  5. Two stages of implementation • Mature system to interface with CGOOS • Four key issues of concern • >70 variables • Including socio-economic variables • Five immediate, priority products to • Initiate system • Establish improved capability • Provide proofs of concept • Advertise the program

  6. Mature System(to interface with CGOOS) Issues of Concern • Population dimensions, land use/land cover and critical habitat alteration (B, C, D); • Sediment delivery (D); • Water cycle/water quality (B, C); • Effects of sea level change, storms and flooding (C).

  7. Proposed Initial Products of C-GTOS • Enhancement of TEMS • Distribution and rate of change of population, urbanization and land use in the coastal environment (B, C, D) • Vulnerability of ecosystem services in deltaic systems (B, C, D) • Management of conservation and cultural sites in the coastal zone (B) • Distribution of sites appropriate for analyses of delivery systems (D)

  8. Coastal variables & Sites added The list of coastal variables result of efforts by the Coastal GTOS scientific panel, through the development of the C-GTOS Plan, identifying variables that best describe monitoring activities taking place at TEMS sites dealing with coastal issues. Variables are grouped according to the four priority coastal issues addressed by C-GTOS: Sediment loss and delivery Water cycle/water quality Effects of sea level change, storms and flooding Population dimensions, land cover/land use and critical habitat alteration

  9. Deltas Priority Product World Deltas Network

  10. Initial Products of C-GTOS through GLCN 1 2 1) digital elevation data to perform geophysical analysis of the delta 2) use of land cover and in situ data to determine ecosystem extent and function 3 3) analysis of threats and vulnerability of ecosystem services.

  11. Potential link to Delta Research And Global Observation Network (DRAGON) • The DRAGON partnership is creating an international community of practice to share data on the great deltas and rivers of the world and to develop comparative models and visualization tools in order to facilitate ecological forecasting regarding climate change and development that ultimately helps in guiding decision making.

  12. Conservation of Cultural and Conservation Sites(Sentinel Systems in Observing Systems) • Selected and limited number of systems to assess response to global and large-scale regional change and promote programme.

(see Hydrobiologia 583:385 for erratum on order of authorship from original. It should read Mazzilli and Christian)

  13. Potential networks of sites • ILTER • MAB • MedWet • TNC • Ramsar • World heritage • Etc.

  14. Initial Product of CGTOS Table 3. Number of global program sites located within various coastal area delineations. Percentage of total number of program sites is indicated in parenthesis (%).

  15. Wetland Inventory and Partnerships(Ramsar and MedWet) Of the 250 sites 69% are within 100 km of the coastline and 36% are within 5 km of the coastline.

  16. C-GTOS Delivery System Network in Mediterranean & Black Sea Region Link to LOICZ Information collected on 127 sites

  17. IGOS Coastal Theme The IGOS-P Coastal Zone Theme Report: The Theme Report provides the basis for the work of the GEO Coastal Zone Community of Practice.

  18. GEO Coastal Zone Community of Practice • The GEO Coastal Zone Community of Practice (CZCP) • The CZCP brings together scientific and non-scientific experts in an effort to support coastal zone management through utilization of Earth observations and derived products. The CZCP focuses both on research and practical applications related to coastal zone management. • The CZCP interacts directly with the User Interface Committee (UIC) of the Group on Earth Observations (GEO). • A main activity of the CZCP is the organization of a series of regional workshops addressing the decision support through Earth observations for integrated coastal zone management.

  19. GEOSS Support for Decision-Making in the Coastal Zone: Managing and Mitigating the Impacts of Human Activities and Natural Hazards in the Coastal Zone A series of (regional) GEO Workshops organized by the GEO Coastal Zone Community of Practice • June 2008 - Mediterranean Region (Greece) • February 2010 – Africa (Benin) • 2010– Northern Africa (Egypt) • Sep/Oct 2010 – Americas (Puerto Rico)

  20. Overview of potential future • Important role in liaising with other coastal programmes in promoting regional OS • GOOS • LOICZ • GEO CZCP • Ramsar and partners • DRAGON • Coastal lagoon networks • US IOOS • Develop deltaic change products • Contribute to coastal vulnerability products and white papers

  21. General recommendations for observing system sustainability: • Sustainable systems need cultivation. Positive feedback mechanisms are required. • Governments are unlikely to provide sustained support without connection to human wellbeing. Observing systems must provide clearly articulated value to society beyond “preserving nature.” • Local monitoring programs in isolation have a significant probability of being non-sustainable. Redundancy among monitoring programs (resilience) should not be discouraged. • Information management plays a central role and must target a timely delivery of products to address environmental problems appropriately. • Sustainable observing systems in the developing world are the largest challenge to global coverage.
