SummaryThe central concept of TERRA-IRIS is to assess the current status and dynamics of the Irkutsk Region’s environment influenced by man-made changes and anthropogenic impact. The project will produce a current assessment of man-made changes and anthropogenic load on forestry environments from industrial pollutions, create dedicated environmental databases integrated in a Geographical Information System (GIS) for the Irkutsk Region. TERRA-IRIS will benefit and contribute from on-going European-Russian cooperation projects (Sib-ESS-C, ESA-IAF FEMINE, ESA GSE Forest Monitoring, EU IRIS). TERRA-IRIS is embedded in ESA’s GSE Forest Monitoring Service in Russia. The primary objective aims at a European capacity for the provision and use of operational services for Global Monitoring of Environment and Security by 2008. A major effort is put on the close collaboration between providers and users, so data and information can be better understood and put into practice. The countries and administrative regions often have to deal with pressing environmental problems such as frequent forest fire events, illegal logging practices as well as other human activities and natural forest disturbances. Due to the large forest areas in Siberia, which are often difficult to access or characterized by insufficient infrastructure and severe climate conditions, frequent monitoring of the forest resources is a great challenge. TERRA-IRIS is designed to meet also the needs of long-term monitoring and will establish therefore a basis for future cooperation in the fields of environmental risk assessments and environmental protection. Major objectives of TERRA-IRIS project are: 1. To create dedicated environmental databases integrated in a Geographical Information System (GIS) for the Irkutsk Region. 2. To create a forest inventory map with special focus on tree type identification and disturbance aspects, e.g. deforestation, logging, burnt areas and insect attack using TerraSAR-X data. Forest area maps will be generated using high-resolution, cross-polarised ENVISAT precision images and TerraSAR-X data at large incidence angles. Change detection analysis will be performed by comparing TerraSAR-X data with existing land cover maps produced in the framework of the EC SIBERIA-II project. For quality control and product verification Landsat TM as well as ground reference data will be used. Emphasis is put onto fire scar detection and the differentiation between crown and surface fires as well as the separation between forest and settlements with TerraSAR-X data. Products are a forest area map, forest area change map, ARD area map and a clear cut and burnt area map. 3. To create an updated land cover classification map with respect to field crop identification and growth stage assessment on basis of TerraSAR-X band data. Focus will be on the determination of feature selection to separate land use classes in different levels of detail, on the derivation of field crop identification and on the derivation of biophysical parameters such as biomass or crop height. Therefore, time series of SAR data shall be analysed and combined with optical imagery. 4. To assess the potential risks for Irkutsk Region forestry environments arising from man-made changes and anthropogenic forcing according to the elaborated scenarios and to develop recommendations on remediation measures. Required data refer to high-resolution spotlight mode (HS) images for validation purposes of existing data provided by the IRIS project and stripmap mode (SM) images in single and dual polarisation for forest monitoring issues. ScanSAR (SC) data are relevant in 2007 to cover the entire study region possibly in synergy with the proposed TERRA-SIBESSC project (also to this AO). Funding will be ensured by the ESA GSE Forest Monitoring and the EC-IRIS projects.
