Research interest

Dr Amwele is an Agricultural scientist and specializes in aquatic toxicology and animal production. My research group works on a range of projects water quality, aquatic toxicology, nutrition, herbal medicinal plant, and environmental pollution. The research aims to understand how pollutants enter the environment (water), accumulate in plants and animals which then ends up affecting the human health negatively. Other studies focused on acute and chronic hazardous effect of chemical and herbal medicinal plant on animal health. Working on fodder plant identification on Namibian rangeland and understanding their nutritional value. Looking at the potential of propagating fodder crops in hydroponic system and distributing the method in the Namibian communal area. Developing new research on pesticide residue, their accumulation and hazardous effects on aquatic organisms leading to their impact on human health.
