Remote sensing assessment of biological activities on built historical structures in a tropical region:  Case of the Osun-Osogbo Sacred Grove UNESCO World Heritage Site, South-Western Nigeria.

A remote sensing study reveals that biological activities, such as algae and moss growth, significantly influence the physical conditions of heritage structures within the Osun-Osogbo Sacred Grove UNESCO World Heritage Site. This research demonstrates how greenery affects thermal and weathering processes on built historical structures in tropical climates, contributing to both degradation and potential conservation benefits. The study integrates satellite imagery, surface temperature data, and 3D modeling techniques to assess spatial and temporal changes in forest cover, erosion patterns, and micro-climatic conditions. Findings provide a framework for identifying monument degradation, guiding sustainable conservation practices in Nigeria and Africa.
