Since the advent of industrial revolution in 1750, global aquatic environmental conditions have been modified from desirable to less desirable as a result of cultural nutrient loadings, siltation and climate change. The ensuing transformations have directly or indirectly triggered mass biotic migrations, loss in biotic diversity and abundance, changes in pelagic food web dynamics and nutrient cycling. The palaeolimnologic relationships between environmental and observed biotic changes are difficult to establish due to paucity of data. My studies are therefore interested in understanding limnological shifts, causes, and ecological impacts associated with nutrient loading and climate change, with a view to providing management solutions that will lead to aquatic health restorations.
