Nigeria - November 18th, 2009

FAPAR, which stands for Fraction of Absorbed Photosynthetically Active Radiation, provides data on the vegetation index of a given zone and can be used to study the changes in the planet’s vegetation system. The color spectrum over land runs from red (1.0), to green, to yellow and white (0.0), while bodies of water appear blue.

In this image of eastern Nigeria (left) and Cameroon (right), photosynthetic activity increases as one moves away from the dry Sahel and towards the coast. Some dark red areas, indicating high photosynthetic activity, are visible near the  Niger River (far left) and the Nigeria-Cameroon border (lower left quadrant). The most active zone is  in that frontier zone, in the Korup and Cross River National Parks, which have a tropical rainforest habitat.
