| KENYA: Land Cover Change Analysis |
 |
Land cover is subject to dynamics driven by anthropogenic and natural
alterations:
- climate-related change (long- and short term)
- burning / fire activities
- cutting and clearing of forests (deforestation)
- grazing activities (intensification of rangelands)
- agricultural encroachments (farming activities)
- fuel wood consumption
- urban expansions (urbanization)
- natural successional processes and regeneration
It is possible to monitor changes in the land cover using remote sensed
products (see example below, Kenya, Landsat 1990/2000) where the detection
of changes can be highlighted using time series of satellite images.
GLCN, through its Land Cover Classifications System (LCCS) and the databases
produced adopting LCCS legends, (i.e. AFRICOVER), can detect and map
changes over time. For example, The AFRICOVER land cover database for
Kenya (1:200,000 scale) was used to detect and quantify changes
against the available Geocover set of satellite imagery (three decades,
1980-2000).
