This study deals with land use and land cover
changes for a 33 years period. We assessed these
changes for eight land cover classes in the south of
Benin by using an integrated multi-temporal
analysis using three Landsat images (1972 Landsat
MSS, 1986 Landsat TM and 2005 Landsat ETM+).
Three scenarios for the future were simulated using
a first-order Markovian model based on annual
probability matrices. The contribution of tree
plantations to compensate forest loss was
assessed. The results show a strong loss of forest
and savanna, mainly due to increased agricultural
land. Natural woody vegetation (“forest”, “wooded
savanna” and “tree and shrub savanna”) will
seriously decrease by 2025 due to the expansion of
agricultural activities and the increase of
settlements. Tree plantations are expected to
double by 2025, but they will not compensate for
the loss of natural woody vegetation cover.
Consequently, we assist to a continuing woody
vegetation area decrease. Policies regarding
reforestation and forest conservation must be
initiated to reverse the currently projected
tendencies. |
