Meet the researcher bringing sustainable solutions to sub-Saharan farmers

Deep Bed Farming is essential because it addresses the issue of compacted, rock-hard earth beneath the topsoil in Malawi. This compact layer prevents water retention and root growth, leading to poor agricultural output.  

By breaking up the hard layer, Deep Bed Farming allows water to penetrate and be stored in the soil, improving fertility and increasing yields. 

Technology, particularly micro electric tractors, allows for the practical implementation of Deep Bed Farming by breaking up the compact soil.  

Solar energy is vital for this as it powers the tractors through a modular microgrid system, making the solution both sustainable and affordable and not reliant on the purchase of fuel.  

This combination of state-of-the-art renewable energy technology and modern farming techniques creates a closed-loop system that makes the use of solar energy economically viable.  

The solar array provides power to the micro electric tractors which enable farmers to access Deep Bed Farming, which increases crop yield and profit, which in turn allows the purchase of energy from the microgrid. We are a long-term, sustainable solution. 

Some of the greatest challenges include overcoming the high cost and scarcity of fuel in rural Malawi, as well as building the necessary infrastructure for solar energy and electric tractors.  

We have been designing the system to be as manufacturable as possible using tooling available in Africa, building not only a supply chain but also a repairable and maintainable system. 

Empowering farmers through Aftrak enables them to increase their yields, improve food security, and become economically self-sustaining.  

The success of these models can uplift entire communities by providing reliable energy access, reducing dependency on costly fuel imports, and promoting sustainable farming practices, potentially serving as a blueprint for other regions in Africa. 

Receiving the $1 million Milken-Motsepe prize was a remarkable achievement, validating the innovative approach and hard work of everyone involved in the Aftrak project.  

It brought global recognition to the importance of sustainable agriculture and renewable energy in transforming rural communities and provided significant financial support to launch the Aftrak initiative.
