Agroecological vegetable farming is considered to be an effective approach to reduce land degradation, carbon emissions and agrochemical use, while improving soil organic matter, sustainability and resilience. However, supporting evidence is often lacking. The Greener Greens project aimed to enhance the income, food security and resilience of smallholder farmers with agroecological practices. It complemented the Veggies 4 Planet & People initiative that fosters vegetable business development, creates employment opportunities, and promotes human and environmental health through regenerative agriculture practices. A wide range of different agroecological practices were introduced to smallholder farmers, with data collected from 137 farmers who participated in the trials where they grew amaranth, African nightshade, kale and pumpkin leaves. Successes were showcased in demonstration days, and market linkages were encouraged through ‘vegetable business networks.’
