The study aimed at assessing the impacts of
mining and other anthropogenic activities on the land-use,
vegetation and livelihood in the Niger-Delta Region,
Nigeria. It is hypothesized that the land use, floristic
composition, and livelihood were significantly affected by
mineral mining. GIS and Remote sensing were used to
collect data, identify, and classify the landuse-landcover.
On the other hand, the local people were also interviewed.
In addition, reconnaissance survey and field data sampling
were used to identify the plant species. GIS analyses tools,
regression and RDA analyses where employed to analyze
the data. The result revealed that oil mining activities,
farming, and logging were the primary socioeconomic
activities which have significant impacts on crude-oil
spillage. The relationship between oil mining and fishing
was significantly high (p = 0.002; R2 = 0.63). The trees
were more vulnerable to the effects of the crude-oil spillage
when compared with other plant functional groups. A net
loss of about 15,500 US dollars per annual was recorded on
the impacts of oil spill to the vegetation. However, with
fewer grasses, about 50% of the vascular plant species
were associated with the 0.5km buffer zone. Integration of
geospatial and statistical analyses was very effective and
successful in analyzing the impacts of socioeconomic
activities on land use-land cover. The use of GIS should be
further applied in studying the spatio-temporal pattern of
basic facilities and species hotspots in the area as this
would consolidate land use-cover conservation against
future crude-oil pollution.
