Dr. Benton Otieno is a Researcher at the Centre for Renewable Energy and Water at the Vaal University of Technology (VUT) in South Africa. Recently he has been engaged by the African Centre for Technology Studies as a Research Consultant for developing and scaling up the best Science, Technology, and Innovative interventions for improved water security in Eastern Africa. Dr. Otieno’s over five years of experience spans extensive research on water and wastewater management, renewable energy, green economy, and climate change mitigation. He previously worked at Lake Victoria South Water Works Development in Western Kenya where he gained vast experience in water quality surveillance, monitoring and evaluation of water service providers, and community mobilization and development. In climapAfrica, his research will seek to integrate anaerobic digestion and ozonolysis for the effective treatment of waste activated sludge and recovery of resources including water for reuse, biomethane for energy production, and struvite and biosolids for agricultural applications.
Climate change expertise and interests
Sustainable water and wastewater management practices and renewable energy. I plan to advance progress on the adaptation to climate change, achieve ‘net-zero’ energy processes, and green circular economies.

I participate at climapAfrica because...
I believe that collaborative research is a key pathway to finding solutions for the world’s complex challenges such as climate change and access to improved water and sanitation services, clean energy, and nutritional food sources. Through the scholarship, I intend to gain international research exposure, broaden my experience and skills in research management, and contribute to the DAAD’s aim of fostering application-oriented research results to tackle climate change in southern and western Africa.
