===What is IMAGE?===
+
[[Category:Glossary]]
−
IMAGE is an ecological-environmental model framework that simulates the environmental consequences of human activities worldwide. It represents interactions between society, the biosphere and the climate system to assess sustainability issues such as climate change, biodiversity and human well-being. The objective of the IMAGE model (version {{#show:IMAGEversion |?HasCurrentVersion}}, released in 2014) is to explore the long-term dynamics and impacts of global changes that result from interacting demographic, technological, economic, social, cultural and political factors.

    • 1. tropical broad-leaved evergreen;
    • 2. tropical broad-leaved raingreen;
  • Temperate (tem)
    • 3. temperate needle-leaved evergreen;
    • 4. temperate broad-leaved evergreen;
    • 5. temperate broad-leaved summer green;
  • Boreal (bor)
    • 6. boreal summer green;
    • 7. boreal needle-leaved evergreen;

IMAGE Natural land cover types (biomes)

  • Ice
  • Tundra
  • Wooded tundra
  • Boreal forest
  • Cool coniferous forest
  • Temperate mixed forest
  • Temperate deciduous forest
  • Warm mixed forest
  • Grassland and steppe
  • Hot desert
  • Scrubland
  • Savanna
  • Tropical woodland
  • Tropical forest

Biome classification

Natural vegetation types (biomes) are classified based on the area shares of the plant functional types (PFT)s and their foliage projected cover (FPC); the mean temperature; and net primary production (NPP) according to the flowchart below.


Flowchart for the classification of natural land cover types (biomes) based on of plant functional types
Natural land cover type (biome) classification from area shares of individual Plant Functional Types (PFT)s (expresses as foliage projected cover, FPC) and mean annual temperature (Tmean). Subscripts of FPC refer to individual PFTs (1: tropical broadleaved evergreen, 2: tropical broadleaved raingreen, 3: temperate needleleaved evergreen, 4: temperate broadleaved evergreen, 5: temperate broadleaved summergreen, 6: boreal summergreen, 7: boreal needleleaved evergreen, 8: C3 herbaceous, 9: C4 herbaceous), tropical PFTs (“trop”) are PFTs 1 and 2, temperate PFTs (“temp”) are PFTs 3-5, boreal PFTS (“bor”) are PFTs 6 and 7, tree PFTs (“tree”) are PFTs 1-7, grass PFTs are PFTs 8 and 9.
