Spatiotemporal analysis of land use dynamics and land surface temperature to detect environmental degradation in Ijebu-ode, Ogun State, Nigeria

In the face of escalating environmental challenges, the change in Land Use
dynamics emerges as critical and persistent significant threat, profoundly
impacting the stability of eco-biodiversity and food security challenges,
especially in developing nations. This study examines the effect of land use/land
cover changes (LULCCs) in Ijebu ode, Ogun State, Nigeria using Landsat
Thematic Mapper (TM) and Landsat Operational Land Images (OLI) captured
from United State Geological Survey repository. Herein, LULCCs maps for 2005,
2010, 2015, and 2020 including Normalized Difference Vegetation Index and
Normalized Difference Built-up Index (NDBI) were examined to retrieve Land
surface temperature of the area through Single-channel algorithm (SCA) method
in order to detect the extent of degradation, contributing to the discourse on
environmental sustainability. The results revealed the quantitative and qualitative
environmental changes in the area, highlighting unprecedented built-up with an
increase of 150.25 % while the non-built-up areas decreased by -56.77 % during
the period of study. Undeniably, satellite remote-sensed data offers valuable tools
to provide ecological information for urban sustainability. This study underscores
the urgent attention from society, government, and stakeholders to manage
population growth and balance human needs for a sustainable environment,
thereby contributing to the broader goal of environmental sustainability.
