Prof. John Gathenya is an associate professor and agricultural engineer with research interest in modelling of multi-functional rural watersheds and other aspects of soil, water and environmental management that deepen our understanding of drivers and impacts of change. He has twenty years’ experience of teaching and research at the Jomo Kenyatta University of Agriculture and Technology in Kenya. As a consultant hydrologist, he has worked for over seven years with international research and development organizations such as CARE, WWF and ICRAF to prepare hydrological baseline studies and monitoring protocols for emerging Payment for Ecosystem Services (PES) Projects in East Africa. Notable projects include ICRAF’s PRESA PES pilot project in Sasumua, Kenya, CARE and WWF EPWS projects in Lake Naivasha in Kenya, Uluguru and East Usambara Mountains in Tanzania and Mara Basin in Kenya and Tanzania. Currently John Gathenya is a research fellow at Walker Institute for Climate System Research at the University of Reading UK but based in Nairobi and involved in supporting research organizations in Eastern Africa doing projects funded by The Rockefeller Foundation and aimed at developing climate change adaptation technologies and building resilience of smallholder rain fed agriculture to climate variability and change.
