African Lives Matter: Wild Food Plants Matter for Livelihoods, Justice, and the Environment—A Policy Brief for Agricultural Reform and New Crops

Abstract

International agricultural policies to address hunger and malnutrition in the tropics and sub-tropics have typically been based on approaches to the intensification of farming systems effective in industrialised economies where the social, economic, and environmental conditions and the infrastructure are very different to those in Africa. The consequence of this short-sightedness has been that agricultural productivity, dependent on ecosystem services from natural capital, has declined in Africa due to ecological and environmental collapse. This has undermined the livelihoods of the millions of smallholder farmers living on the brink of the cash economy, leading to severe social injustice. This review summarises advances in smallholder agriculture’s sustainable intensification in the tropics and sub-tropics, leveraging the domestication and commercialisation of wild indigenous tree species that produce nutritious, marketable, and useful food and non-food products. These are grown within diversified and multifunctional farming systems together with conventional food staples and local orphan crops to reduce land degradation, pollution, water extraction, and nutrient mining while promoting services such as pollination and other ecological functions. The benefits arising from this approach simultaneously address hunger, malnutrition, poverty, social injustice, and a stagnant economy, as well as important global issues such as climate change, loss of biodiversity and environmental degradation. Addressing these issues may also reduce the risk of future pandemics of zoonotic diseases, such as COVID-19. This set of serious global issues epitomise our divided and dysfunctional world and calls out for action. Enhancing sustainable smallholder productivity using indigenous and wild foods is an important international policy and business intervention, vital for achieving the 2030 Sustainable Development Goals and the rebalancing of the global economy by restoring natural capital within new African indigenous food industries.
