Harnessing Africa’s Forgotten Flora: A Path to Nutritional Security and Sustainable Agrifood Systems

The rich tapestry of Africa's indigenous crops, comprising 30,000 varieties, is little more than a footnote in the modern agrarian landscape, where a trinity—wheat, maize, and rice—rules supreme. This narrow horticultural horizon has come at a significant cost, with 90% of food deriving from just 20 plant species and 60% of calories consumed in Africa and across the globe coming from the aforementioned trio. These crops’ dominion represents a lost opportunity in a landscape historically teeming with agrobiodiversity—a term capturing the myriad crop and animal types that once nourished the continent.

The stark paradox is that the continent, capable effusively of self-sustenance, is beleaguered by hunger. A staggering 20% of Africa's population encountered this plight by 2020, with the figure likely escalating due to the ravages of natural calamities and the Covid-19 fallout. Urgent policy shifts and cultural revivals are imperative to rekindle the cultivation and consumption of Africa's forgotten flora; these include resilient and nutrient-rich species such as the Bambara groundnut, cowpea, pigeon pea, millet, sorghum, and various African leafy greens like amaranth and wild mustard.

Solutions and strategies germinate from recognizing the dual role of these crops: they are resilient against harsh climates and are integral to social and economic empowerment. They can endure aridity and scorching heat, rendering them ideal for cultivation on lands that defy the mass monoculture approach. Moreover, these crops can be pivotal in uplifting smallholder farmers and bolstering food and nutrition security. Societal development and income augmentation for rural households hinge on diversifying cultivars, which could also invigorate local markets and create employment, particularly benefitting women who are often the custodians of these indigenous crops.

However, prevailing agricultural systems, forged in the cauldron of the Green Revolution, have promoted an industrial monoculture that’s scarcely adapted to Africa's variegated ecosystems, ensuing in ecological degradation and a paradoxical coexistence of hunger and agricultural plenty. This model has also faltered in the face of climate change's inexorable hold, with erratic floods and droughts already undermining yields. Realigning focus onto underutilized species could instill resilience in agricultural practices while preserving Africa's fertile soils from further despoliation.

A critical piece of the puzzle is governmental support through research funding, creative incentives, and educational campaigns to elevate the status of these plants from “neglected” to “nurtured.” The aim is twofold: to dispel the associated social stigma and to enlighten the public on their health and environmental advantages. These policies should extend support to women, furnishing them with credit facilities, land, water rights, and access to viable markets to foster their empowerment and inclusion in nascent value chains.

Only with an Afrocentric agrifood system in place—one celebrating and harnessing Africa’s heritage and natural capital—can the continent aspire to food sovereignty, sustainable livelihoods, and an equitable agrarian domain. These "opportunity crops" could serve as keystones for a future where Africa's agrodietary heritage flourishes once more, providing a resilient front against adversities while honoring its inherent diversity. The opportunity is ripe to redefine Africa’s relationship with its traditional food sources and make a stride toward environmental and nutritional fortitude.
