| Summary: | This study developed a land cover and
land use mapping framework specifically designed for
agricultural systems in the Sudan-Sahel region. The mapping
approach extracts information from inter- and intra-annual
vegetation dynamics from dense stacks of Landsat 8 images.
The framework was applied to create a 30-meter spatial
resolution land use map focusing on the 2015 agricultural
landscapes in northern Nigeria. The map provides up-to-date
information with a high level of spatial and thematic
detail, resulting in a more precise characterization of
agriculture in the region. The map reveals that agriculture
is the main land use in the region. Arable land represents
on average 52.5 percent of the area, which is higher than
the reported national average for Nigeria (38.4 percent).
Irrigated agriculture covers nearly 2.2 percent of the total
area, reaching nearly 20 percent of the cultivated land when
traditional floodplain agriculture systems are included,
which is above the reported national average (0.63 percent).
There is significant variability in land use in the region.
This study demonstrates the feasibility of multitemporal
medium-resolution remote sensing data to provide detailed,
up-to-date information on agricultural systems in the arid
and sub-arid landscapes of the Sahel region. |
