Activity Data Mapping


GAF AG and its partners have developed a series of methods and techniques to account for green house gas emissions emanating from deforestation and forest degradation and establish baselines (baseline scenarios) against which emission reductions could be eventually measured.

The scope of activities currently eligible under REDD+ include: deforestation; forest degradation; enhancement of carbon stock; forest conservation and sustainable forest management. This service segment focuses on monitoring the area extent of deforestation and forest degradation. Based on remote sensing technology, methods are developed to monitor and quantify deforestation and forest degradation. In cases where the objective is to set up historical baselines; historical remote sensing data data are employed to determine previous rates of deforestation. Deforested areas are further classified into IPCC compliant land use categories:

  • forest land
  • crop land
  • grass land
  • wetland
  • settlement
  • other Land Use

Developed methods employ both optical and Radar remote sensing technologies to produce wall-to-wall forest cover and forest cover change maps for large areas

Methods have also been developed to account for planned forest degradation activities like selective logging. To account for forest degradation due to uncoordinated activities like fuel wood extraction - this service segment has developed socio-economic approach to account for such activities.

Deforestation and Degradation Mapping

The products the Consortium can offer for mapping and monitoring deforestation (e.g. to estimate baseline scenarios) are mainly based on Earth Observation satellite data. Today available EO datasets include also historical data (e.g. from 1990. 2000, 2005) and allow the monitoring of forest cover/forest cover changes and historical baseline assessments in the frame of Wall-to-Wall mapping approaches. The offered products build a good information basis for relevant stakeholders (e.g. REDD Focal Points, UNFCCC Focal Points and Ministries) in developing countries to implem,ent REDD policy processes.

The following product portfolio comprise of different Thematic Map products relevant for the REDD process and are compliant to IPCC Guidelines:

  • Forest Cover Map
  • Forest Cover Change Maps
  • Land Cover Maps

Product Description

Forest Cover Maps showing forest vs. non-forest, optionally, other wooded lands. Non forest class can be subdivided into several broad land use classes. Forest definitions adhere to National or International standards (e.g. FAO, IPCC 2006,...), or specific national and regional forest definitions. Forest classification is obtained from EO data from different sources using image classification techniques. Forest Cover Change Maps are comparing different epochs (e.g. deforestation rate between 1990 and 2000) in time to calculate historic and current gross/net deforestation rates. The mapped changes between two epochs can then be further classified into IPCC compliant Land Use classes.

All thematic maps can be provided as raster or standard vector datasets and the geographic reference system as well as the Minimum Mapping Unit (e.g. 0,5 to 5 ha) can be adapted to specific policy and user requirements.
