Seasonal Dynamics of Coastal Landscapes: A Critical Review Using Remote Sensing and GIS
Abstract: Coastal landscapes are among the most dynamic environments on Earth, undergoing continuous transformation due to both natural processes and anthropogenic activities. In India, particularly along the southern coastal regions of Andhra Pradesh, Tamil Nadu, and Kerala, shoreline morphology and sediment transport patterns are significantly influenced by seasonal monsoons, cyclones, storm surges, waves, tides, and changing river discharges. These factors contribute to varying rates of coastal erosion, accretion, inundation, and land- …

A Synthesized Effect of Urban Modification and Net Radiation on the Climate of Lagos Metropolis, Nigeria
Abstract: Land cover adjustment which includes urban landscaping, agriculture crops or hardscapes forconstructing and parking lots promote variations in the energy and radiation balance. Due tothe above listed modifications, the surface temperatures and near-surface air temperatures overurban patches are generally higher than those over rural areas, thus resulting in an Urban HeatIsland (UHI). In this study, urban landscape and Land Surface Temperature (LST), netradiation, and Normalized Difference Vegetation Index (NDVI) data …
