  1. AG-06-04Forest Mapping and Change Monitoring LoycheWilkie,Mette (FAO) Adam Gerrand (FAO) Ivan Petiteville, CEOS Slide # 1

  2. Task Description • Integrate international efforts on assessment and monitoring of forests and forest changes using a combination of ground and satellite information and internationally agreed standards. • POC: FAO • Lead: GTOS, USA Slide # 2

  3. Key activities Decide on objectives, approaches and required funding (Washington, October 2006 and Rome March 2008). Build consensus on standards in land characterization, interpretation methods and validation(2006-2008). Establish framework for linking in situ forest observations and satellite observations(Ongoing). Participate & assist related land cover mapping projects (e.g. GLOBCOVER). (Ongoing) 5. Develop protocol for selected disturbances and disturbance history (Not started in earnest. Premiminary work on fragmentation). Support capacity building on assessing forest area and forest area change(Ongoing. A global Forest Monitoring Symposium planned for end 2008 and a series of regional and subregional workshops in 2008 and 2009). Slide # 3

  4. Outputs and deliverables Identification of key actors and agreement on objectives & approaches for a global remote sensing survey of forests (as part of FRA 2010). An agreed methodology for the FRA 2010 Remote Sensing Survey (RSS). A framework for linking statistical forest data, in situ forest observations, and satellite observations as part of an international forest and forest change assessment. An augmented global sampling frame that is capable of identifying emerging regional issues such as fragmentation and deforestation. Capacity building workshops. Slide # 4

  5. Progress to date Good progress on FRA RSS design with wide consultations on sampling framework. Consultant Ralph Ridder’s report online www.fao.org/fra - Kotka meeting FRA National reps - June 2006- First meeting Washington Oct 2006 – agreed that FRA 2010 RSS forms the overall framework for GEO task, FAO will lead with wide range of partners - Several meetings with key implementing partners FRA 2010 launched Rome 4-6 March 2008 FRA 2010 Remote Sensing Survey Task Force of 22 key countries (80% worlds forest) set up with partners at first meeting March ‘08 Slide # 5

  6. Progress to date • GEO meeting Japan 14-16 April incl. forest monitoring (http://www.earthobservations.org/meetings/20080414_16_geoss_asia_pasific_summary_report.pdf) • GEO meeting in Geneva 16 June on proposed new Forest Monitoring Task • FRA2010 RSS funding from EU in Aug 2008 (E3.6m) • Remote Sensing Scientist position was advertised Sept 08 • Release of Landsat global datasets (by Nov?) will allow pilot testing of analysis of change detection in 22 Task force countries • GOFC-GOLD Forest Monitoring workshop Germany 13-17 Oct • GEO forest monitoring meeting, Brazil from 4 to 7 Nov • Feb 2009 FAO meeting on forest degradation FRA special study • 2009: Capacity building workshops and survey implementation. • 2010: Data analysis • Final report expected in 2011 – for Year of the Forests Slide # 6

  7. Data preparation by SDSU University • Matt Hansen and team at South Dakota University (FRA2010 RSS partners) to collect and analyse MODIS and Landsat data • Draft data viewer and download system developed http://globalmonitoring.sdstate.edu/projects/fao/index.html

  8. Data preparation by SDSU University • Users can view and easily download MODIS tree cover imagery and Landsat data for all the FRA RSS sample tiles

  9. Radar work by Jena University • Jena University partners in FRA RSS to collect and analyse radar data for sites with cloud or other data gaps http://www.frasar2010.uni-jena.de/index.html

  10. Concerns/issues • Concerns/issues which will determine our ability to deliver the end product on time: • A large number of the existing Landsat Geocover images (~1975, 1990 and 2000 datasets) need to be re-rectified. As these images are from all regions, we cannot start the implementation until this re-rectification procedure has been completed (if we do, we would have to re-do much of the work later). NASA/USGS has indicated that this work will be completed by Oct/Nov 2008. • We need a reconfirmation that this timeline is still valid. • We are also intending to use the mid-decadal data set, but face a time constraint if this is not ready until end of 2008 (current schedule) or later. • Strong support from countries and goodwill from partners but now waiting for re-rectified LANDSAT from USGS (delays? maybe Dec 08?!)
