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.

Across Kampala, families use saucepans, cooking pots, frying pans, kettles, and pressure cookers every day. Makerere University School of Public Health is now investigating whether some of these items may expose households to lead, a toxic heavy metal that can enter food during cooking if contaminated materials are used to make them.
The year-long study, titled “Assessment of Lead Contamination in Domestic Cookware, Supply Chains, and Exposure Pathways in Informal Settlements of Kampala,” was launched on 11 June 2026 at MakSPH’s ResilientAfrica Network (RAN) in Kololo. Supported through the Lead Exposure Elimination Project (LEEP), with funding from Bloomberg Philanthropies, and led by Mr. Douglas Bulafu, Mr. Tom Okade, and Dr. Rawlance Ndejjo, the study will assess total and leachable lead levels in commonly used cookware, map how the products are sourced, distributed, and sold, and identify feasible interventions to reduce household exposure to lead.
Ms. Prossy Nabaggala, Senior Standards Officer at the Uganda National Bureau of Standards, pictured centre, consults with study co-investigators Mr. Tom Okade and Mr. Douglas Bulafu during the launch of MakSPH’s study on possible lead exposure from domestic cookware in Kampala.
Today, lead remains a major and preventable public health concern globally. WHO reports that no level of exposure is known to be without harmful effects and estimates that lead exposure contributes to more than 3.5 million deaths worldwide, mainly through cardiovascular effects. Children and women of child-bearing age are said to be especially vulnerable, with exposure linked to impaired brain development, reduced learning ability, harm to unborn children, high blood pressure, cardiovascular disease and kidney damage.
In Uganda, lead exposure concerns also extend to household products and informal markets. Aluminium pots and saucepans, particularly low-cost locally fabricated items, may be made from recycled scrap metal. If contaminated materials are used, lead may leach into food during cooking or other food-contact use, creating a possible route of exposure in homes.
During the launch, Assoc. Prof. David Musoke, Head of MakSPH’s Department of Disease Control and Environmental Health, underscored the importance of involving stakeholders throughout the research process. He said engaging stakeholders from the generation of research ideas to implementation and dissemination helps ensure findings do not remain within the University but are translated into evidence that can inform policy, practice, and community action.
“We engage with stakeholders throughout the research process, from developing ideas and designing projects to implementation and dissemination,” Dr. Musoke noted. “I am pleased that this workshop brings together policymakers, the Ministry of Health, non-governmental organisations, Kampala Capital City Authority, academia, staff and students. This helps ensure that research findings do not remain at the University but are beneficial to our stakeholders.”
Assoc. Prof. David Musoke delivers remarks during the study launch, emphasising sustained stakeholder engagement to ensure research findings inform policy, practice and community action.
He observed that the study was timely, as it addresses an important yet under-examined public health concern, arguing that while lead exposure from paint, pipes and drinking water has received considerable attention, exposure through cookware remains less understood despite its widespread use in many households. He added that the new research builds on MakSPH’s broader work in disease control and environmental health and will generate critical evidence to inform action on lead exposure risks in Uganda. Dr. Musoke also commended the study team for initiating this work.
Previously, MakSPH researchers Mr. Abdullah Ali Halage, Mr. Tom Okade, Dr. James Muleme and Dr. Juliet Kiguli, together with Mr. Ahmada Zziwa and Mr. Robert Mugabi, assessed knowledge, perceptions and practices related to heavy metal contamination and health risks among residents living near Kiteezi in Kampala, Katikolo in Mukono and Nkumba in Entebbe. The study, done in 2024, reached 505 residents and captured community and frontline perspectives from people living and working around the dumpsites. It showed how daily contact with dumpsite environments may expose communities to toxic heavy metals such as lead, arsenic, cadmium, and mercury through soil, water, air, food crops, animal products and waste-handling practices.
Evidence from the study, funded by the Government of Uganda through the Makerere University Research and Innovation Fund (MakRIF) and disseminated on 26 June 2025, showed that heavy metal exposure risks around the three municipal dumpsites within the Kampala Metropolitan Area were shaped by both environmental conditions and community behaviour.
Dr. Sabrina Kitaka, Member of the MakRIF Grant Management Committee, pictured centre, with research team members including Mr. Abdullah Ali Halage, Mr. Tom Okade and Dr. Juliet Kiguli, following the dissemination of findings on heavy metal exposure risks around Kampala Metropolitan dumpsites on 26 June 2025.
Although residents lived near dumpsites where waste can release heavy metals into soil, water and food chains, 76.4 per cent could not define heavy metals, and only 45.9 per cent had adequate knowledge of contamination and related health risks. Gaps extended to daily exposure pathways, with 38.4 per cent unaware that vegetables grown near dumpsites may contain high heavy metal levels and 39.8 per cent unaware that milk or meat from animals grazed near dumpsites may also be contaminated. More than half viewed dumpsite soils as fertile, 50.7 per cent considered such milk safe, and 51.3 per cent believed dumpsite waste could be used as manure.
The study recommended stronger risk communication, environmental monitoring, safer land-use enforcement and community education. The work on lead in domestic cookware now extends this focus from dumpsite-related heavy metal exposure to a possible household pathway. Mr. Douglas Bulafu, an early-career researcher and Principal Investigator of the study, said the team will examine whether commonly used cooking pots, saucepans and related utensils contribute to exposure, and generate evidence to guide safer cookware use, standards and market oversight.
“Lead contamination has been documented from sources such as paint, fuel and air pollution, but less attention has been given to cookware as a potential pathway of exposure. That is the gap this study seeks to address,” Mr. Bulafu said. “We focused on Kampala because it has many informal settlements, small-scale cookware workshops and a large consumer market where low-cost cookware is widely produced, sold and used. When people buy these products, they often do not know where they were made, what materials were used, or whether they contain lead. The supply chains are also poorly understood, meaning households could be exposed without knowing.”
Mr. Douglas Bulafu, Principal Investigator, speaks during the launch of the MakSPH study on possible lead exposure from domestic cookware in Kampala, highlighting the need for evidence to guide safer cookware use, standards and market oversight.
The study will use a cross-sectional, mixed-methods design to connect laboratory evidence with supply-chain realities in Kampala’s informal settlements. The team will purchase about 100 cookware samples from open-air markets, roadside vendors, retail shops and supermarkets in Kisenyi, Katanga, Bwaise, Namuwongo, Banda and Kasubi, test them for total and leachable lead, and conduct about 30 key informant interviews across the supply chain to understand how cookware is sourced, produced, distributed and used.
Findings will be validated with stakeholders and used to identify feasible interventions, including stronger regulation and enforcement, raw-material control, better manufacturing practices, market surveillance and consumer awareness. The evidence is expected to support standards development, product testing, policy uptake, safer manufacturing practices and public guidance on cookware choices, helping reduce household exposure to lead and associated health risks.
Speaking on behalf of the Ministry of Health, Dr. Didacus Namanya, a health geographer and environmental health expert, welcomed the study, saying scientific evidence on lead exposure is critical because public health decisions can have lasting consequences for life and wellbeing.
Dr. Namanya implored the research team to ensure the evidence from the study informs decisions beyond academia, shaping policy, strengthening public health practice and guiding practical measures to reduce lead exposure in communities. He emphasised that research should not remain in the “ivory tower” but reach decision-makers and the public, so that evidence from the study translates into policy, practice and stronger protection for communities.

Kampala — On Saturday, a car park on the campus of Makerere University in Kampala became the stage for a continental emergency response. Delegates, dignitaries and diplomats gathered in the tent outside the Infectious Diseases Institute (IDI), a research institute owned by the university, for the formal launch of the Continental Incident Management Support Team (IMST), a joint Africa Centres for Disease Control and Prevention (Africa CDC) and World Health Organization (WHO) operation racing to contain the Bundibugyo strain of Ebola sweeping through the Democratic Republic of the Congo and, increasingly, Uganda. After the ribbon-cutting, guests were led inside to tour the team’s new home at IDI’s McKinnell Knowledge Centre, where the command offices have now been set up.
Dr Chris Baryomunsi joins delegates for a group photograph at the IMST launch, Infectious Diseases Institute, Makerere University.
The numbers explain the urgency. As of 21 June, more than 1,000 confirmed cases and 269 deaths had been recorded across the two countries, the vast majority in Ituri Province in eastern DRC. Uganda’s tally stood at 20 cases and two deaths, almost all traced to cross-border movement from the DRC. Eighty-two health workers have been infected, 18 fatally, a toll that helped push the WHO to declare a Public Health Emergency of International Concern in May, mirrored days later by Africa CDC’s own continental emergency declaration.

Until now, the international response has been coordinated remotely, a patchwork of video calls and scattered logistics that officials admit slowed decision-making. The Kampala launch marks a shift from that fragmented model to a single, physically co-located command centre housed at IDI’s McKinnell Knowledge Centre, bringing case management, surveillance, logistics and risk communication specialists under one roof. From there, the convoy of delegates moved on to Kajjansi, on the outskirts of Entebbe, for the formal activation of the IMST’s regional logistics hub, the facility tasked with staging and rapidly deploying protective equipment and medical supplies across the outbreak zone.

For Uganda’s health minister, Dr Chris Baryomunsi, the symbolism was as important as the logistics. Speaking at the launch, he argued that no nation can consider itself protected until its neighbours are equally prepared, framing cross-border solidarity as an operational necessity rather than an aspiration. He also announced a new memorandum of understanding with the DRC establishing joint Ebola treatment centres and laboratory services in the border towns of Aru and Kasenyi, warning that outbreak response cannot succeed while transmission continues unchecked on one side of a shared frontier.
Dr Chris Baryomunsi speaks as the guest of honour at the launch of the Continental Incident Management Support Team, Infectious Diseases Institute, Makerere University.
The WHO’s regional emergency director, Dr Marie-Roseline Belizaire, described the unified command structure as transformative, saying it would pool resources across agencies, cut duplication and keep field decisions anchored to scientific evidence. Africa CDC’s Dr Tolbert Nyenswah confirmed the team, specialists in case management, infection prevention, logistics and contact tracing, has now relocated physically to Kampala to work closer to the epicentre. Eleven epidemic-prone African nations, including Rwanda, Burundi, Angola and the Central African Republic, are participating in the preparedness effort even though most have not registered a single case.
Dr Marie-Roseline Belizaire, WHO AFRO’s regional emergency director, speaks at the launch of the Continental Incident Management Support Team in Kampala.
For IDI and Makerere University, hosting the command centre carries weight beyond the immediate crisis. IDI’s executive director, Dr Andrew Kambugu, said the institute had provided a fully equipped space, now installed at the McKinnell Knowledge Centre, enabling real-time communication between field teams, regional governments and international partners in Geneva, and framed the moment as proof that academic institutions can engage directly with pressing societal problems rather than observe from the sidelines.
Dr Andrew Kambugu delivers welcome remarks at the launch of the Continental Incident Management Support Team, Infectious Diseases Institute, Makerere University.
That framing matters for a continent whose research infrastructure has often been treated as peripheral to its own health emergencies. By anchoring the IMST’s command function within a Ugandan public university rather than in a foreign capital, the launch signals a modest but symbolic rebalancing: an African-led institution taking custody of an African-led response. The day’s itinerary made the point physically as well as symbolically: from the ribbon-cutting in Makerere’s car park, to the tour of the new command offices, to the drive out to Kajjansi to switch on the logistics hub, delegates traced the full chain of the response they had just committed to running.
