We’ve all done it—tossed leftovers, ignored wilted greens, or shrugged at a half-eaten meal. Food waste is a quiet guilt we all share, a reflex in a world of abundance and scarcity. But what if this small act connects to a larger global issue? On February 26, 2025, experts from Uganda, Sweden, and beyond gathered in a virtual seminar, asking, “How can we nourish ourselves without harming the planet?” Hosted by the Centre of Excellence for Sustainable Health (CESH), the discussion revealed a harsh truth—our food habits are draining the Earth.

The discussion on sustainable food systems marked the beginning of the annual four-part global conversation on sustainable health, organized through a collaboration between Sweden’s Karolinska Institutet and Uganda’s Makerere University under the auspices of CESH.

In Kampala, the paradox is stark. Every day, 750 tons of food waste fill the city’s landfills, enough to feed thousands. Rotten mangoes spill from crates in Nakasero Market, and half-eaten Rolex wraps pile behind street stalls. Uganda’s Food Rights Alliance shows 37.8% of this waste comes from plates and markets. Across East Africa, organic waste, like spoiled vegetables and discarded tubers, makes up 79% of urban trash—a grim reflection of broken systems. Beyond this is a city stuck with piles and piles of organic trash, which has previously been fatal with a slide in one of Kampala’s major landfills. Meanwhile, 26% of Uganda’s children remain stunted.

At the heart of this week’s global conversation was the WWF’s Living Planet Report 2024, a sobering revelation of a 73% decline in global wildlife populations since 1970. Freshwater ecosystems have hemorrhaged 85% of biodiversity, Latin America’s species richness has plummeted by 95%, and Africa—home to smallholder farmers who feed millions—has lost 76%. “Nature is disappearing at an alarming rate,” warned Harold Turinawe, WWF Uganda’s Forest Markets Transformation Manager, his voice weighted with urgency.

“We are pushing Earth’s systems to irreversible tipping points, and despite the increase in food production and land use and the destruction of habitats, the world is still hungry; we have over 735 million people going to bed hungry every other night. The contradiction is striking,” Turinawe added.

The report highlights the Amazon’s lush canopies that are felled for cattle ranches. The interplay of man’s unsustainable utilization of Mother Nature, leading to the food paradox, feast, famine, and ecological ruin, underscores the urgency of addressing global goals in a coordinated manner.

The report’s indictment of industrial food systems is clear: agriculture claims 40% of habitable land, 70% of freshwater, and drives 25% of greenhouse emissions. Yet, 735 million people still starve nightly. “Our obsession with monocultures and processed foods isn’t just destroying habitats—it’s failing humanity,” said Dr. Rawlance Ndejjo, the seminar’s moderator and a public health lecturer at Makerere University.

Florence Tushemerirwe, a Ugandan public health nutrition expert based at Makerere University’s School of Public Health, pointed out the irony: 26% of children are stunted, while obesity rises among adults in Uganda. “We grow nutrient-rich crops but export them, leaving people dependent on cheap, processed imports. In fact, many people do not appreciate their nutrient value,” she said. Uganda’s iodine-depleted soils now rely on fortified foods—a temporary fix for a growing crisis.

All through the seminar, the message was clear: we are wasting abundance while ecosystems crumble and people go hungry. “Our salt is iodized because our soils no longer provide it. Biodiversity loss isn’t abstract—it’s stealing nutrients from our plates. But if we don’t maintain our nature’s health, or our environmental health, or our natural resources health, it means that whatever food we grow, we actually do not carry the nutrients we need to maintain a diverse diet,” said Tushemerirwe.

The panel dissected global food trade’s role. WWF’s Turinawe lamented, “90% of deforestation is for agriculture. In Uganda, the once-vibrant wetland ecosystems of Lwera at the shores of Lake Victoria now face severe degradation due to large-scale rice growers; in the Amazon, its cattle ranches.”

Dr. Rachel Marie Mazac of Stockholm Resilience Centre stressed Europe’s complicity: “Sweden’s ‘virtual biodiversity loss’—importing deforestation via beef and soy—shows how our diets export destruction.”

“From a Swedish perspective, we are highly dependent on imports, particularly raw materials, which contribute significantly to biodiversity loss in other regions. It’s difficult to pinpoint the exact impact, especially with biodiversity, but there’s a concept of “virtual impact,” says Dr. Mazac.

Food consumed in Sweden, though produced elsewhere, contributes to biodiversity loss in those areas. The issue links to trade, food production, and distribution. It’s not just about production or waste but also equitable distribution.

Dr. Ndejjo added starkly, “You could be eating a burger from a cow grazed on razed Amazon forest. Guilt isn’t enough—we need systemic change.”

Amid the grim statistics, the panelists outlined a roadmap for redemption: nature-positive agriculture, subsidy policy reform, improved localized diets, global accountability, and honest discussions on the GMO dilemma.

Turinawe emphasized the need for agroecology in extension services—integrating trees, crops, and livestock to rebuild soil health and biodiversity. He stressed while critiquing Uganda’s Parish Development Extension Model for prioritizing enterprises for profit over sustainability. “We are saying get one million to a farmer. What are they producing? They are engaging in commodities that are predetermined. Nobody’s talking about Mother Nature. Who takes care of the soil? Who takes care of the water needs? Who takes care of the diversification we are talking about? But diversification in the diet begins with diversification on the farm. So my first issue is strengthening the agricultural extension services,” says Turinawe.

Adding that things like soil health management, land tenure system farmer-to-farmer network for peer learning, and fair farmer subsidies should be key to planning and agricultural extension.

“In Uganda, where I come from, and currently in Kampala, if you head north towards Zirobwe in Luweero District, you’ll find people we call Bibanja owners—essentially squatters who don’t own the land they occupy. These individuals cannot engage in sustainable agriculture as we’re discussing; their focus is survival. What we need are programs that give farmers secure land rights, which can motivate them to invest in soil health and environmental conservation—investments that take time. Improving soil is not a short-term effort; it requires long-term actions like planting trees, integrating practices, and using farmyard manure. None of this is realistic for someone who fears being displaced tomorrow. We need to approach this challenge collectively.”

Subsidies must reward sustainable practices, not industrial giants.

“Why not tax breaks for farmers using organic manure?” Turinawe challenged. “I would love to hear that a farmer that is engaged in sustainable cocoa production and coffee production gets a tax holiday rather than having a blanket of investors getting a holiday. Put subsidies and investment incentives in the right direction. We shall spur production, and of course, this will also bring in corporate partnerships, and we can make our supply chains safer, better, more green, and more sustainable,” Turinawe added.

Dr. Mazac noted that “nature-positive production can feed the world by optimizing crops, livestock, and wild fisheries, and supporting aquaculture that works with wetlands, not against them.” For Mazac, policy is key: She is also an advocate of subsidies and taxes that benefit farmers. Those that ensure incentives that improve soil health and maintain water quality as well as tackle climate change in order to make sustainability profitable.

“We must rethink trade to avoid widening the gap between food-producing areas and markets and instead support local farmers. Subsidies and taxes should empower these communities to nourish their populations before focusing on exports. While exports generate income, they also have significant impacts. A possible solution is changing production systems, but we must also shift dietary and consumption habits, making this a collective effort, not just an individual responsibility.”

Tushemerirwe is hungry for reviving indigenous crops and regulating predatory marketing. “Awareness is power. We must teach communities to value their traditional foods over processed substitutes.”

“There is good food grown in rural areas and available in markets, but people don’t recognize its value due to lack of guidance. We need food-based data guidelines to raise awareness. The Uganda Ministry of Health has a draft for this, along with draft policies to regulate unhealthy food marketing, especially to children. Junk food is advertised everywhere: hospitals, schools, and even street billboards, with fast food chains clustered together. We must regulate this and educate people on the nutritional benefits of eating what they grow over imported alternatives,” she stated.

Dr. Ndejjo believes these draft guidelines to regulate unhealthy food marketing should be finalized into policies and urges policymakers and implementers to prioritize the urgent need for these documents.

The conversation also weighed in on the genetic engineering in agriculture for increased crop yields, popular for GMOs, a dilemma that panelists called for their democratization rather than demonizing them. While Dr. Mazac cautioned against corporate-controlled seeds, Turinawe acknowledged their potential: “If democratized, drought-resistant crops could save farms in a warming world.”

Dr. Mazac noted that while in Europe and the European Union, they are not allowed to grow or sell foods that have been genetically modified, the essence of them should not be overlooked, since they are a technology that seeks to solve the future food crisis.

“GMOs aren’t inherently evil. Drought-resistant crops could save farms—but corporate patents trap farmers,” she said.

Turinawe added, “Our approach to GMO’s is a measure one bordering more on ethics and responsible use of GMOs; we see GMOs as a tool to promote resilience, especially since everything has changed—the food we once relied on can no longer grow in the same way. If GMOs help improve crop resilience, that’s a valuable tool. However, there are concerns that companies like Monsanto could use the GMO technology as a tool of exclusion, e.g., the fear of monopolizing future seed markets. This is where caution is needed.”

A Call for Radical Collaboration

The seminar’s resounding theme was unity: multi-sectoral collaboration is non-negotiable. From street food vendors to policymakers in the boardrooms, every actor must align. “Food systems aren’t siloed,” Dr. Mazac asserted. “They’re woven into climate, economy, and culture.”

“I think we need to sit and agree and engage quite regularly and find solutions for us to be able to produce food but sustainably,” concluded Tushemerirwe.

The Path Ahead

CESH’s global conversations on sustainable health are a microcosm of a global awakening, especially in tracking progress to meet our goals for 2030 and beyond: This seminar on food systems emphasizes the interconnectedness of food security and biodiversity. With the next UN Climate Summit (COP29) on the horizon, the panel’s message is clear—transformative change is possible, but only through courage, equity, and an unyielding reverence for nature.

The silent teachers: why body donation matters

In every hospital, there is a moment when knowledge becomes a matter of life and death. A doctor must know where to place an incision, how to avoid damaging major organs, how to identify a nerve, how to deliver a baby safely, how to interpret a scan, or how to explain disease to a worried family. That knowledge does not begin in the operating theatre, it begins much earlier, in the anatomy laboratory.

For generations, the study of the human body has been the foundation of medical education. The regular use of human bodies for medical training purposes began in the late Middle Ages and spread during the 18th and 19th centuries. Initially, anatomists depended on gallows, poor houses, mental asylums, or jails as sources of bodies. However, the 1960s and 1970s saw the emergence of wilful body donation. Before students become doctors, surgeons, dentists, nurses, physiotherapists, radiographers, and other health professionals, they must first understand the human body in its real form. They must learn not only from books and diagrams, but from the body itself. This is why cadavers, though silent, remain the most important teachers in medical education. In simple terms, a cadaver is a dead human body used by health professions students to study anatomy; and Anatomy is the study of the physical structure and organization of the human body, both at macroscopic and microscopic levels.

As the Department of Anatomy at Makerere University College of Health Sciences prepares to commemorate the “silent teachers” whose bodies are used for medical education on June 11, 2026, Uganda is invited to reflect on a subject that is rarely discussed in the public domain, willed body donation. Body donation simply means a person willfully donates their body for educational purposes after death, and consent to it in life. This is a sensitive topic, but it is also a deeply human one. It touches our beliefs, families, culture, understanding of death, and responsibility to future generations.This commemoration ceremony is not symbolic but, it is a public statement that the contribution of silent teachers is sacred, educational, and deeply appreciated.

To donate one’s body after death is not an ordinary decision; it is an altruistic act of extraordinary generosity. It is a final gift to society. It allows health professions students to learn and appreciate the human body before they treat living patients. Cadavers are therefore not “specimens”, they are silent teachers and partners in medical education who continue to serve humanity even after death. Learning anatomy using a cadaver helps students to understand and appreciate the complexity of the human body, appreciate its natural variations, and develop the confidence and competence needed to serve the public. Students are also taught laboratory etiquette that emphasises dignity, empathy, and utmost respect for the cadavers, which attributes they carry into the clinical years when they interface with hospital patients.

In Uganda, where the demand for health workers continues to grow, medical education must be strengthened at every level. Our country needs well-trained doctors and health professionals who can serve in hospitals, health centres, universities, research institutions, and communities. But good training requires good teaching resources. One of these resources are the silent teachers who never complain, but impart immeasurable knowledge to future health professionals. Modern technology has introduced many useful tools into medical education. Students can now learn from videos, computer applications, digital images, plastic models, three-dimensional models, and virtual platforms. These tools are important and should be embraced, however, they cannot completely replace learning from the real human body. A cadaver teaches what a diagram cannot fully show; the true position of organs, the texture of tissues, the relationship between structures, and the natural differences that exist from one person to another. More importantly, cadaver-based learning teaches respect. It reminds students that medicine is not simply a technical profession, it is a calling rooted in human dignity. The first lesson students learn in the anatomy laboratory is that the body before them belonged to a person who had a name, a family, a story, and a life. That lesson shapes how they later treat patients.

Currently, most, if not all universities in Uganda, and similar settings in Africa use unclaimed bodies for learning Anatomy. The use of cadavers in Uganda is governed by the Penal Code (Anatomy Rules) of 1957 that permits public hospitals to transfer bodies unclaimed for at least 14 days to a medical training institution like Makerere University. Unfortunately, these cadavers are used without the consent of the deceased because most of them are unknown and with no known relatives to claim them. Many opponents to the use of unclaimed bodies opine that the practice is unethical. There is a global push toward ethical use of cadavers in medical education, where a person consents and bequeathes his/her body for medical education when still alive. For this practice to be sustainable, there is a need for a well regulated body donation program. Unfortunately, the concept of willful body donation is still not well understood by many people, and neither has it been a topic of public debate. Further, there are lots of myths surrounding death and dying in Africa, including Uganda that have hindered the establishment of successful body donation programs. Willingness to donate bodies for medical education is however, influenced by several factors including cultural and religious beliefs, respect for the dead and the need to fulfil burial rites, fear for mutilation and disrespect, to mention a few. These concerns are real and should not be dismissed. But they should be addressed with accurate information, openness, and utmost respect.

It is important to understand that body donation does not mean that a person is forgotten. On the contrary, it creates a legacy. A body donor may teach hundreds of future health professionals, in that way, one person’s final act of generosity can touch and save countless lives. This is kind of patriotism is largely unkown in Uganda and we do not speak about enough. We often talk about serving our country through leadership, business, farming, teaching, parenting, or community service. But there is also service beyond life. Body donation is one way of saying: “Even when I am gone, let me contribute to the health of my people.”

Currently, Uganda now has more than 15 universities training medical students and the demand for cadavers for learning anatomy is on the rise. Actually, the supply of cadavers cannot fulfil the demand, and medical educationists need to find alternative source of cadavers. Wilful body donation is the answer.

Uganda needs a national conversation on body donation. There is a need for deliberative public engagement involving various stakeholder including the public, religious and cultural leaders, civic leaders, the media, educationists, health professionals, medical training institutions, etc.

This commemoration ceremony will involve inter-denominational prayers for the silent teachers, and a reflection of their contribution to healthcare in Uganda. We hope this ceremony will provoke public debate on a subject that is hitherto considered a taboo by many. We talked about some of these issues last year, in the first ever such ceremony in Uganda, and have received several requests for more information on the procedure for donating one’s body for teaching purposes upon death. Like President Obama’s said, “yes we can”, an the dialogue starts from you and me. You are all invited for the commemoration ceremony at 9.00 am on June 11, 2026, at the Makerere University School of Public Health auditorium on main campus.

To donate one’s body is to give a final lesson, a final service, and a lasting gift to the nation.

How to protect yourself and your loved ones from Ebola. Ministry of Health, Kampala Uganda, East Africa.

The Democratic Republic of Congo (DRC) and Uganda recently reported an outbreak of Ebola Virus Disease (EVD), which is a serious and often deadly disease caused by a person being infected by the Ebola virus.

The virus spreads through direct contact with body fluids such as blood, saliva, faeces, vomit, urine, sweat or genital fluids from a person who is infected with EVD.

The symptoms of EVD usually develop after 8 – 10 days from contact with an infected person and may include fatigue, high fever, headache, sore throat, muscle and joint pains, vomiting and diarrhea and in severe cases, bleeding.

What should we do as the Makerere University community?

The Chief, Makerere Health Services, Prof. J.K. Byamugisha advises as follows:

Avoid unnecessary contact such as shaking hands, hugging etc.
Place alcohol disinfectants or hand washing equipment at all entry points within the University and ensure everyone is using them.
Students should sit in single-person chairs while in class, avoiding contact with their neighbours.
Do not sit too close to one another especially in frequently crowded places such as classrooms, library or any other waiting area.
While at the University Hospital, wash hands a the gate, use alcohol disinfectant at the reception.
All patients should have a maximum of one caretaker – others can check on them by calling.
Avoid bringing luggage to the University Hospital.
Target to do as instructed by the health worker.
For further information and guidance on Ebola, please call Dr. Charles Basigara on Tel: 0702 966652 and Sr. Eunice Namubiru on Tel: 0779 950978 (Contact persons for the University Health Services)
