In Burkina Faso, the degradation of forest resources has led to the
implementation of strategies to preserve and restore plant formations.
To this end, the Wakou communal forest (FC) and the
Diapangousylvopastoral zone (ZSP), in the east of the country, have
benefited from forest management. This study analyzes the impact of
these management on vegetation by mapping the different land-use
units. To this end, 08 Landsat images from 1989, 1999, 2009 and 2018
were processed. Field observations and data collection were used to
perform a supervised classification using maximum likelihood. The
results show that in the FC, the area of wooded savannah has increased
significantly, rising from 1.95% in 1989 to 54.53% in 2018. Shrub
savannah has decreased from 89.22% in 1989 to 42.14% in 2018.
Fields have also declined, respectively from 13.55% in 1989 to 2.22%
in 2018. In the ZSP, the results show that wooded savannah increased
from 4.40% to 17.92% between 1989 and 2018. Shrub savannah
regressed from 72.70% in 1989 to 55.50% in 2018. Fields increased
from 16.34% to 22.55% over the same period. The change in land use
units shows that in the FC, shrub savannah has regressed in favor of
wooded savannah. It has gained 78.21ha and is the largest surface area
at 83.76 ha. In the ZSP, shrub savannah decreased by 105.19 ha in
favor of wooded savannah and by 69.10 ha in favor of fields.
Monitoring of management activities is recommended to ensure
sustainable management of the forest resource.
