In the vibrant farmlands of Embu County, Samuel Njagi is leading a quiet revolution one worm at a time. As a Village-Based Advisor (VBA), Samuel has turned his farm into a living lab of regenerative agriculture (RA), where nothing goes to waste and everything adds value.
Through vermicomposting, Samuel transforms organic waste into high-quality fertilizer and liquid foliar feed. Each litre of vermicompost tea, sold at KES 150, is mixed with five litres of water to nourish crops naturally and boost yields. But Samuel doesn’t stop there—he uses excess red worms to feed fish in his pond, creating a fully integrated system that delivers both productivity and profit.
Supported by the STRAK project, funded by AGRA and implemented by CGA, Samuel now trains other farmers on how to replicate this model. He’s helping fellow producers shift from synthetic inputs to nature-powered solutions that are sustainable and cost-effective.
“RA has taught us that waste is not waste it’s opportunity,” he shares. Yet, the work is not without its challenges. “RA requires presence. You can’t leave it and expect results. I can’t meet the demand for vermicompost tea alone,” he says, calling for more youth to get involved in hands-on, sustainable agribusiness.
“From waste, I grow crops, feed fish, and build livelihoods. Regenerative agriculture is full-circle farming and it works.”

Samuel’s model is proof that with the right knowledge and innovation, RA turns resilience into a thriving enterprise right from the ground up.
