A quiet fading is happening across Africa. It’s not a sound, but a taste a slow erosion of flavor, of history, of a way of life that was once intimately tied to the land. The memory of eating yams fresh from the field is becoming more distant for many. These were not just any yams; they were robust, thick-skinned treasures hiding within them a powerful nutritional legacy; dense fibres and slow-releasing carbohydrates that provided a steady, long-lasting energy, the kind that fueled entire communities and anchored them through seasons of labour. This was more than sustenance; it was a cultural anchor. In Uganda, the yam harvest was a profound ritual, a celebration woven with threads of gratitude for the fertility of the land, the blessings of rain, and the strength of a community working in unison. It was a ceremony that acknowledged the earth as a partner, not just a resource.

Our diets were a vibrant mosaic of resilience and intelligence. Alongside the noble yam, we consumed hardy grasses like millet and sorghum, which possessed the incredible ability to bend under the harsh wind and relentless sun, yet not break. They thrived where other grains would wither, offering their seeds generously. Then there was the cassava root, a lesson in perseverance, growing in depleted soils where little else would take hold. And we cannot forget the legumes the cowpeas and the bambara nuts which were the quiet agriculturists of our fields. They did more than just feed our children with essential protein; they worked in symbiosis with the earth, fixing nitrogen back into the soil, rebuilding its vitality for future seasons. These seeds millet, sorghum, yam, African rice, fonio, and cowpeas were our biological inheritance. They were not accidental; they were carefully selected and adapted over countless generations to our specific challenges: to our patterns of drought, to the intensity of our sun, to the unique composition of our soils, and to the rhythms of our cultural and communal lives. They were the very definition of food sovereignty.

Yet, today, a walk through many local markets tells a different story. The vibrant diversity of these indigenous crops is becoming harder to find. The stalls, once a kaleidoscope of shapes, colours, and textures from local farms, are now increasingly dominated by a monolithic trio: rice, wheat, and maize. This great dietary shift, this replacement of a diverse, locally-adapted food basket with a narrow set of global staples, is not without consequence. It coincides with a silent, creeping health crisis sweeping across the continent. The World Health Organization reports a staggering rise in non-communicable diseases (NCDs) like hypertension, diabetes, heart disease, and cancers. In the WHO African Region, these diseases were responsible for approximately 37% of all deaths in 2019, a sharp and alarming increase from around 24% in the year 2000. Zooming into Uganda, the picture is even more concerning, with NCDs accounting for about one in every three deaths. This is not a mere statistical correlation; it is a direct consequence of a fundamental change in what we eat.

This health transition is paralleled by an economic one: a growing dependence on food from beyond our borders. Uganda’s food imports made up about 10.7% of all its merchandise imports in 2023. While the absolute volume might be debated with some reports suggesting only about 5% of consumed food was officially imported in the 2013-19 period the tangible, visible trend is undeniable. The seeds being sown, the vegetables being sold, and the staples being piled on market tables increasingly carry the invisible label of “imported.” But the true tragedy, the profound irony at the heart of this story, is not just the importation itself, but what was discarded to make room for it. The traditional crops that sustained our ancestors for centuries those very yams rich in fibre, the millet and sorghum that stood resilient through drought, the cowpeas and bambara nuts that enriched our soils were deliberately cast aside. Under colonial and later post-colonial thinking, they were branded as primitive, backward, even “barbaric.” A cultural shame was engineered around our own nutritious staples, creating a preference for foreign foods that were perceived as modern and superior.

The bitter pill we now swallow is that these same crops, once scorned as the food of the poor and uneducated, are being rediscovered by the global health and wellness industry. They are now packaged, branded, and shipped back to Africa from Europe and elsewhere as trendy, expensive “super-foods.” We see our own millet flour, once ground by our grandmothers, now marketed on sleek packaging as a premium, gluten-free alternative. Fonio, a grain that never needed pesticides to thrive, is now sold in ready-made breakfast bowls at a price that places it out of reach for many who once cultivated it. Sorghum is reborn as a healthy snack, and moringa powder, a leaf that grew like a weed in our backyards, is touted as a miracle supplement. These were once our daily, affordable staples, the bedrock of our nutrition. Now, they return to us in shiny packaging, carrying premium price tags, while the shelves of our own local shops are increasingly stocked with imported rice, processed wheat products, and ultra-processed snacks that are often high in sugar, unhealthy fats, and salt. The result is a devastating triple loss: our food culture is outsourced, our health is threatened by the dietary shift, and the genetic heritage of our seeds is disappearing from our fields.

Let us take a moment to consider the yam in greater detail, as its story is a microcosm of the larger issue. In many Ugandan communities, the yam was never just a source of calories. It was a potent symbol of strength, endurance, and a deep, unbreakable connection to the land. Its value was embedded in its very biology. Its complex carbohydrates delivered sustained energy, preventing the sharp blood sugar spikes and crashes associated with refined modern foods. Its abundant fibres fed a healthy gut microbiome, which we now know is central to overall health. Its cultivation practices, often intercropped with other species, maintained soil health and biodiversity. Yet today, the yams that once filled local markets in abundance have been supplanted by imported potatoes, wheat-based breads, cheap, nutrient-stripped white rice, and canned goods. The seeds of yams and other local crops are losing ground, both literally and figuratively, in favour of commercial hybrid seeds that often require more water, fertilizers, and pesticides. We are losing not only a food, but the entire sacred relationship—the interconnected cycle of saving the seed, the farmer who knows its ways, the land that gives it life, and the plate that it nourishes. This severing of the food chain is a severing of culture itself.

Meanwhile, the alarming rise of non-communicable diseases is no mere coincidence. It is the predictable outcome of a dietary pivot away from what sustained our grandparents. Diets now rich in processed carbohydrates, cheap imported staples low in fibre, high in sugars, and laden with refined oils and fats are a recipe for metabolic disaster. In Uganda, the prevalence of raised blood pressure is steadily increasing, diabetes now affects about 3% of adults, and the risk of premature death from the four main NCDs is around 22%. On the continent more broadly, the World Health Organization warns that NCDs are poised to become the major cause of death, overtaking communicable diseases unless we take decisive action. This is not simply a matter of nostalgia or longing for a romanticized past. It is a pressing issue of public health resilience, nutritional security, and social justice. To ignore this link is to ignore the very real suffering in our communities.

When we choose to return to our traditional seed systems when we actively plant millet and sorghum, cultivate yams, cowpeas, and bambara nuts, and revive the cultivation of African rice we are doing far more than just growing food. We are initiating a powerful cycle of renewal. We rebuild our soils through regenerative practices that work with nature, not against it. We diversify our diets, ensuring a wider intake of essential vitamins, minerals, and fibres that protect against disease. We empower local farming communities, especially women who are often the custodians of this ancestral knowledge, strengthening rural economies from the ground up. Most importantly, we reclaim our food sovereignty the right to define our own agricultural and food policies, to control what we grow and what we eat. These crops are not relics; they are solutions. They require less external input, are naturally adapted to our often challenging climatic conditions, support the fibre-rich diets that combat NCDs, and help shield us from the health traps of ultra-processed imports.

We must therefore collectively challenge the destructive narrative that our traditional foods were “barbaric” and outdated. The opposite is true: they were sophisticated, climate-resilient, nutrient-dense, and deeply culturally grounded. The world now honours them as super-foods in health food stores across the globe while we allow their seeds to leave our fields and appear on our grocery shelves as luxury imports. It is time to flip that story on its head. The seeds belong here. The yams, the millet, the sorghum, the cowpeas they are not artifacts for a museum; they belong in our soils, on our plates, and at the very heart of our vision for the future.

So today, we raise a call. It is a call to invest in our biological capital by funding community seed banks and seed exchange networks that preserve and multiply the genetic diversity of African crops. It is a call to support the smallholder women farmers who hold the deep, generational knowledge of how to cultivate yams, millet, and sorghum in harmony with the land. It is a call to reform agricultural and trade policies so that local crops are actively cultivated, marketed, and valued, creating a supportive ecosystem for their growth. It is a call to build robust local markets and value chains where our staple seeds feed our own people first, rather than a system where nutrition is shipped away only to be sold back to us in packaged boxes. Let Uganda and all of Africa reclaim the foods that have sustained us for millennia. Let us honour this heritage not just in memory and story, but on every plate, in every home, and in every market. Our heritage is not lost, forgotten, or obsolete. It is waiting, patiently, in the earth, in the knowledge of our elders, and in the resilience of our seeds, ready to be planted once again.
