Wamalwa is one of the pioneer students in GROW BIOINTENSIVE® Sustainable Mini-Farming from Manor House Agricultural Centre in Kitale, Kenya. After completing the course, Wamalwa was employed by Manor House for 8 years as a trainer. He has been training farmers and other organization staff on GROW BIOINTENSIVE® Sustainable Mini-Farming ever since. Between 1995 and 2000, he cofounded and worked with the Environmental Action Team (EAT), a non-governmental organization whose main objective was to train groups of women farmers on Grow Biointensive Agriculture and carry out on-farm research.
Wamalwa completed an internship at Ecology Action in California (1998) under the mentorship of the founding “father” of GROW BIOINTENSIVE® Sustainable Mini-Farming, John Jeavons. Following the internship, he went back to Kenya and continued to teach his community to raise food sustainably using GROW BIOINTENSIVE® Sustainable Mini-Farming.
Wamalwa worked with Vi Agroforestry project as a field officer (2003-2008), entrusted with the responsibility of training farmers on sustainable agriculture.
He is currently in his final stage of becoming a soil recommender, after attending a 3-year study in soil test analysis and recommender (STAAR) organized by Grow Your Soil in collaboration with Ecology Action.
