In the village of Mwansambo, where conventional farming methods often lead to low and unpredictable yields, Memory Lyton has become a beacon of change. For over a decade, she has been a participant in a long-term research project aimed at proving the viability of Conservation Agriculture (CA) in Malawi, demonstrating that lasting impact requires more than quick fixes.
The project, spearheaded by the International Maize and Wheat Improvement Center (CIMMYT) and Total LandCare (TLC), began with just six small on-farm trials. The goal was to test and adapt sustainable farming approaches, such as no-till planting and intercropping maize with legumes, to the challenging local conditions—including difficult soils and erratic weather. Lyton and her husband joined the effort, turning their plot into a “mother trial” that has now run for over 10 years.
Lyton’s most successful plot showcases a system where she intercrops maize with cowpea and rotates them with groundnut and pigeonpea. The legumes provide natural nutrients to the soil and protect it from erosion, a stark contrast to the conventional fields in the area. The visible results—greener leaves and larger cobs—have turned her plot into a learning hub for other farmers.
This peer-to-peer learning model has been a powerful tool for scaling adoption. Farmers are more likely to trust what they see in a neighbor’s field than what they hear in a workshop. Lyton’s plot is one of a network of 60 mother trials and 1,240 smaller “baby trials” across the country, which allow farmers to test and adapt new methods on their own land.
While challenges like erosion and the slow pace of adoption persist, the long-term data and the commitment of farmers like Lyton show that Conservation Agriculture is not just a theory, but a practical solution to improving yields and building resilience against climate change. The sustained success of these trials underscores the importance of consistent, long-term funding to achieve genuine and lasting agricultural transformation.
