Background & Context

Kenya's agricultural landscape is undergoing a significant transformation, with a growing emphasis on organic farming and sustainable agribusiness. The country's commitment to climate-smart agriculture is evident in various policy frameworks aimed at improving soil fertility, enhancing food security, and boosting farmer incomes. However, challenges persist, particularly for smallholder farmers who form the majority of the agricultural sector. Monoculture, the practice of growing a single crop repeatedly on the same land, often leads to soil degradation, increased susceptibility to pests and diseases, and reduced biodiversity.

Intercropping, on the other hand, offers a natural solution by mimicking the biodiversity found in natural ecosystems. When applied with strategic crops like maize and moringa, it becomes a powerful tool for rejuvenation. Moringa, often hailed as a 'miracle tree,' is renowned for its rapid growth, drought tolerance, and nutrient-rich leaves. Its deep root system helps break up compacted soil, improving water infiltration and nutrient cycling. Furthermore, as a leguminous plant (though technically not a true legume, it hosts nitrogen-fixing bacteria), moringa contributes significantly to nitrogen fixation, enriching the soil for companion crops like maize. This symbiotic relationship forms the bedrock of a more resilient and productive farming system in Kenya.
