Vegetation density/distribution in the high Arctic
Hugo Ahlenius, UNEP/GRID-Arendal
The current vegetation density and distribution in the high Arctic can be calculated using satellite images. The vegetation index, 'greenness' (NDVI) represents a benchmark of the presence and ratio of photosynthesis. In monitoring the vegetation, scientists can keep an eye on the situation and use the index as an indicator of climate change - increased temperatures would enable the forest and tundra to move further north.
