Comparative assessment of machine learning algorithms and Ordinary Kriging for predictive mapping of soil clay content in a tropical Guinea Savanna

Clay content is an important determinant of soil physical and chemical behaviour, influencing water retention, nutrient availability, and agricultural productivity. Accurate spatial prediction of clay distribution is therefore important for digital soil mapping and sustainable land management. This study compared Rando...

Comparative Assessment of Machine Learning Classifiers for Land Use/Land Cover Mapping in a Tropical Savanna Landscape

Accurate land use/land cover (LULC) information is essential for environmental monitoring, agricultural planning, and sustainable land management, particularly in rapidly changing tropical savanna landscapes. This study comparatively assessed the performance of Random Forest (RF), Support Vector Machine (SVM), and Clas...
