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.

On October 15, 2021, the beep of a glucose monitor flatlined in our living room. My mother, Rebecca Nabiteeko (R.I.P.), took her last labored breath as her veins, swollen, burning, and numb, finally surrendered to a decade-long siege by diabetes. Her final days were a cruel liturgy: mornings began with insulin injections, and nights ended with prayers to a God who never answered. “Nsaba Yezu, mpone obulwadde bwa sukaali,” she prayed for deliverance from the sugar sickness. The same sickness that caused numbness of her feet, then her sleep, and finally her life. I miss her.

In our little cramped Kyebando-Kisalosalo home, medication such as pregabalin, Metformin, and Insulin Mixtard—became part of the day’s meals and everyday companions as relatives. We memorized their shapes: the amber vials crowding the dining table, the syringes tucked like shrapnel in drawer corners. Her body was a battleground. Her faith, a fragile ceasefire.

Her story is not unique. It is now becoming every household’s and a Ugandan story. Our country is under attack! While HIV, cholera, and malaria dominate headlines, a quieter killer stalks Uganda: non-communicable diseases (NCDs) like diabetes, hypertension, and cancer now claim 1 in 3 lives, eclipsing infections as the nation’s grim reaper.

“Our clinics are grappling with constant drug stockouts. For hypertension, diabetes, and asthma medications, funding covers just 2% of the actual needs,” reveals Dr. Freddie Ssengooba, a professor of health economics at Makerere University School of Public Health (MakSPH).

In one of the Health Policy Advisory Committee (HIPAC) meetings of Uganda’s Ministry of Health, where key stakeholders gather, a concerning reality about medicine availability was shared.

In schools, teenagers trade 500-shilling cigarettes like sweets. In markets, soda and unregulated sweetened juices flow cheaper than clean water. Uganda’s health system, already strained by several public health issues, is buckling under the NCD surge. “80% of the early 335 COVID-19 deaths in Uganda had NCD comorbidities as an underlying condition,” stated Dr. Eric Segujja, a public health systems researcher, while coronary heart disease, once rare in Africa, now claims 12% of Uganda’s disease burden.

This is a plague of policy, profit, and paralysis, a war where lobbyists outgun public health advocates and sugar drowns out science. My mother didn’t just die of diabetes. She died in a system that incentivizes manufactured epidemics while pushing back on public health responses.

At a dissemination meeting on the political economy analysis of health taxes on unhealthy commodities in Uganda at Kabira Country Club in Kampala in late January this year, Dr. Ssengooba emphasized that, “When discussing NCDs, we need to be very practical.”

Adding that, “Currently, we rely heavily on a few donors and pharmaceutical companies, who provide us with a set of donated drugs each year. If these donors begin to reduce their support, similar to what we’re seeing with the US in the coming days, we will face even greater challenges. This is a critical issue: as we talk about NCDs, there’s no provision within the national budget to address medicine shortages. While there are healthcare professionals trained to manage these diseases, they may end up advising patients to purchase medicines from pharmacies—something that’s not affordable for many, especially those without financial means.”

The culprits? Cheap, sophisticated distribution channels and aggressively marketed unhealthy commodities. For instance, between 2015 and 2023, beer production rose by 42%, soft drinks by 67%, and cigarette sales surged despite taxes.

A presentation titled “Impact of Taxation on the Production, Sales, Revenue, and Consumption of Selected Unhealthy Commodities in Uganda: A Nine-Year Analysis” reveals a significant increase in the production of non-alcoholic beverages, particularly sugar-sweetened drinks, over the years. The highest production levels in the country were recorded during the 2022/2023 financial year. Richard Ssempala a Makerere University lecturer at the School of Economics and a current PhD candidate at Osaka Metropolitan University in Japan, who is also one of the researchers, attributes this growth to the rise in the number of factories and small-scale firms entering the market, coupled with low tax rates on these commodities.

Are Health Taxes, a “Best Buy,” Stalled by Competing Interests?

The World Health Organization (WHO) ranks health taxes on tobacco, alcohol, and sugary drinks among its top “Best Buys” to curb NCDs. Yet in Uganda, implementation faces fierce resistance. Dr. Henry Zakumumpa, a health systems and NCDs researcher at Makerere University, says industry lobbyists have impressed upon government technocrats, people, and commissioners at the Uganda Revenue Authority that when you increase taxes, then there will be distortion of the economy due to low consumption and the government won’t get those taxes, which he says is not true.

“When the taxes remain low, we as public health advocates realize that we shall not achieve our objective of reducing consumption of cigarettes and tobacco because they become affordable. Young people in secondary schools can afford cigarettes, which, of course, as we know, lead to cancer and heart disease. The tobacco industry is interested in maintaining taxes at a level where they’re ineffective, where they are so low that the prices are so low and young people can afford them,” said Dr. Zakumumpa.

But do health taxes work?

Studies that have been conducted elsewhere have shown that, when you increase taxes, the government increases revenue, and also the population reduces consumption of harmful products.

While the industry argues that taxes generate government revenue, a 2017 report by the Center for Tobacco Control in Africa (CTCA), based on a World Bank study, revealed that for every dollar the Ugandan government receives in tobacco taxes, it spends four dollars treating tobacco-related diseases. The government incurs costs at the Cancer Institute, Lung Institute, and Heart Institute, treating individuals with lung cancer, throat cancer, and heart disease linked to smoking in their youth.

“The industry has been successful in misinforming the public, even government officials, by scaring them that if they increase taxes, the economy will suffer and the government will lose revenue, which we have found is actually misinformation,” argues Dr. Zakumumpa.

Dr. Segujja explains, “Health taxes collide with national priorities like the industrialization growth trajectory that the government is pursuing and getting a bulk of the population from the subsistence to a cash economy. Manufacturers of alcohol, tobacco products, and sodas advance this as the rationale for their businesses and, along the way, were attracted to the country with tax incentives to contribute to this objective. Now, they argue new levies will kill jobs and take them out of business.” Industry lobbying has kept Uganda’s tobacco taxes at 30% of retail prices, far below WHO’s 70% recommendation.

The Chemical Hook

For the smokers, every puff injects their veins with 70 cancer-causing chemicals. Smoking doubles their risk of diabetes or that 90% of lung cancers trace back to this habit. But they know one thing: they can’t stop and this is how big tobacco engineers addiction in Uganda’s backyard

“Tobacco is one of the most addictive products,” explains Dr. Zakumumpa. “But do you know why? Manufacturers lace it with nicotine—a chemical trap designed to hook you for life.”

The irony is as bitter as the smoke. In rural Uganda, farmers have chewed raw tobacco leaves for generations without addiction. But in the hands of multinationals like British American Tobacco (BAT) and Marlboro, those same leaves are chemically altered. Nicotine, absent in natural foliage, is added like a sinister seasoning, transforming a plant into a predator.

Profitability of their businesses thrives through repeated consumption by a bulk of consumers.

“They want you as a tenant for life,” Dr. Zakumumpa says. “Even when your lungs scream, your wallet empties, or your blood sugar spikes. When the poor can’t afford cigarettes, they smoke less. The rich? They fund their own demise,” he adds notes.

But isn’t this the science of slavery?

Science demonstrates that nicotine is not only addictive, but also a master manipulator. It rewires brains to crave more, while tar and formaldehyde, some of the 7,000 chemical substances, carve silent graves in lungs. Yet Uganda’s tobacco taxes remain among the lowest globally, keeping packs accessible to teens.

“This isn’t commerce,” Dr. Zakumumpa argues. “Its chemical warfare, and the casualties are in our wards, gasping for air.”

He advises those who are addicted to enroll in nicotine reduction therapies and healthcare treatment at centers designated to help people with tobacco addiction.

“There is something called the National Care Centre (NACARE); we have Serenity Centre Uganda. We have about five centers which treat people who have tobacco addiction and who want to leave tobacco because it’s a chemical addiction, so they should approach the School of Public Health, they can approach us researchers, we can link them to these centers and they will leave and drop this habit,” says Dr. Zakumumpa

Revenue vs. Health, the Fiscal Tightrope  

Uganda’s dilemma mirrors a global challenge. While health taxes could reduce NCD risks and fund healthcare, policymakers fear economic fallout usually advanced by opponents of tax increases. “Taxes on unhealthy commodities are sensitive, fought against by companies”—acknowledges Ssempala. Yet data from his nine-year analysis demystified this: Production and sales of taxed goods like beer and sodas keep rising, even as revenues plateau. During COVID-19, sales dipped briefly but rebounded sharply.

The Ministry of Health’s Dr. Oyoo Charles Akiya remains pragmatic:

“We need compromise. If manufacturers won’t accept higher taxes, let’s mandate health warnings or limit marketing to children.”

Dr. Akiya is the Commissioner of Health Services-Non-Communicable Diseases, and he hopes there can be a path forward through coalitions, evidence, and political will. Despite hurdles, advocates see hope. South Africa’s success in taxing sugary drinks and Kenya’s tobacco levies offer blueprints.

Regionally, a coalition of East African NCD managers is advocating for unified policies. The 4th Global NCD Alliance Forum, held at the Convention Centre in Kigali, Rwanda, on February 13, 2025, was the first of its kind in Sub-Saharan Africa. The event brought together 700 advocates, experts, and ministerial representatives from over 66 countries working in NCD prevention and care. This forum is a key global health forum as we race to the 4th UN High-level Meeting on NCDs, scheduled for September 2025 in New York.

“Change requires top-down pressure,” says Dr. Akiya.

With multinationals at the centre of manufacturing these commodities, exerting enormous pressure sometimes may prove difficult to confront as individual countries.

“We’re engaging the AU and UN to put NCDs on presidential agendas.” Locally, the Ministry of Health is mobilizing patients with lived experience: “They matter the most. The media plays a crucial role in this endeavor and holds significant importance for us. We cannot leave them out in these efforts. The leadership at the Ministry of Health, the minister, and the PS [Permanent Secretary] are all passionate about NCDs,” he added.

Is it a race against time or a behavioral issue?

As Uganda’s youth embrace processed snacks and tobacco, the clock ticks. “Every day without action, we lose more people to preventable diseases,” warns Professor Ssengooba.

The other day, Mubiru (not his real name) was jogging on the street, and a motorcycle taxi called Boda Boda knocked him, and he has just come out of the cast. He’s trying to manage NCDs; he got injured. At a Kampala hotel buffet, 28-year-old Miriam (not her real name) stares at her plate—a mountain of matoke, fried rice, boiled rice, vegetable rice, roasted gonja (plantain), and three golden potato wedges. “Finish it all,” her aunt insists. “Food is a blessing!” But Professor Ssengooba sees a different truth in these heaping portions: “Our plates have become battlegrounds. We pile carbohydrates like trophies—fried, boiled, mashed—while our bodies crumble.”

Uganda’s love affair with carbohydrates has turned toxic. Meals once centered on balanced staples like beans and greens now drown in oil and starch. “We’ve confused ‘tasty’ with ‘excessive,’” he says, adding that “at weddings, funerals, and even home dinners, its six carbohydrates competing on one plate. Why? Tradition says ‘more is generous.’ Science says, ‘more is deadly.’”

At what cost? Surging diabetes and hypertension rates. “We’re eating our way into clinics,” he warns. Yet change faces cultural roadblocks: How do you convince a nation that less on the plate isn’t disrespect—but survival? In this high-stakes battle between public health and profit, Uganda’s choices will shape a generation’s survival.

The first day of the case-finding activity began with an orientation session at the Emergency Operations Center (EOC) offices at the Ministry of Health (MoH). The briefing was led by Dr. Wenani Daniel, Lubwaama Bernard, and Mr. Daniel Kadobera, who provided an overview of the current status of the Ebola Virus Disease (EVD) outbreak caused by Sudan ebolavirus (SEBV) in central Uganda. A key focus of the session was adherence to strict infection prevention and control (IPC) measures including maintaining a safe distance, avoiding direct contact, refraining from entering homes, and not eating or drinking in the field.

To enhance efficiency, the team was divided into three groups, ensuring that each group included at least one clinician for proper assessment of inpatient department (IPD) registers and patient files. The groups were then deployed to their respective sites: Saidinah Abubakar Islamic Hospital, Mulago National Referral Hospital, and a buffer zone within a 2km radius around Saidinah Hospital.
