300 million African pastoralists eke out a living from small cattle herds. Without good markets and veterinary services, many animals die before sale, and there is little incentive to maintain healthy grasslands. Mafisa provides vet services, ensures regenerative grazing, and links herders to markets in Zambia. Herders can make a lot more money in a way that drives healthier grasslands. Mafisa aligns profits and impact: regenerated grasslands make cattle fatter, veterinary service ensure they are healthier and have more offspring, and market access drives more sales at better prices.
