Abstract :
The rural environment has always served as
a place of agricultural and animal production, refuge,
recreation and leisure for riparian towns in sub-Saharan
Africa. With the strong climatic variability and the
demographic growth, natural resources undergo intense
exploitation which lead to often irreversible ecological
imbalances. Biodiversity is plagued by deforestation,
wildfires, water pollution, poaching, extinction, the
introduction of invasive alien species and overgrazing.
This dynamic of agro-pastoral resources was carried out
in the Municipality of Ouassa-Péhunco in Benin. The
objective of this research is to analyze the mapping of the
dynamics of land use units in the Municipality of
Ouassa-Péhunco in a context of socio-environmental
changes. To carry out this study, the phytosociological
records were made. Remote sensing data (SPOT 5
images from 1990, SPOT 6 from 2005 and SENTINEL
from 2020) made it possible to assess the various spatiotemporal changes in land use. The mapping of spatiotemporal changes in vegetation revealed that the area of
natural plant formations in the Municipality has sharply
declined by more than 38.17% between 1990 and 2020 in
favor of mosaics of fields and fallows. Closed formations
(gallery and riparian forests, dense dry forests and open
forests and wooded savannas) fell by 32.95%. Land
tenure and land use methods constitute the agricultural
management methods among farmers in the
Municipality of Ouassa-Péhunco. Cultural practices are
based on the exclusive use of chemical inputs.
