To highlight changes and anomalies in vegetation dynamics,
a ranking was done for each pixel of NPP and RUE for each year with data.
The trend in this ranking was then used as means to identify areas with relative
increases and decreases in vegetation in the Sahel. By combining the absolute (NPP)
and rain adjusted (RUE) regional ranking trends, areas with strongly anomalous
behavior could be identified. The map shows areas with trends in regional ranking in NPP.

RUE, or
