We Are Pushing Nature to the Edge—But Solutions Are Within Reach: Global Conversations on Sustainable Health
By Davidson Ndyabahika and Johanna Blomgren
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.

A major milestone in Uganda’s efforts to reduce newborn mortality was marked on June 17, 2026, when Makerere University College of Health Sciences graduated the first cohort of fellows from the Perinatal and Neonatal Medicine Fellowship Programme.
The pioneering cohort of five specialists completed the two-year sub-specialty fellowship designed to equip pediatricians with advanced competencies in newborn care, leadership, research, advocacy, and neonatal intensive care. The programme is accredited by the Uganda Medical and Dental Practitioners Council and is implemented through a partnership involving Makerere University, Mulago Specialised Women and Neonatal Hospital, Kawempe National Referral Hospital, St. Francis Hospital Nsambya, Seed Global Health and Elma Philanthropies.
Speaking at the graduation ceremony, the Principal of the College of Health Sciences, Prof. Bruce Kirenga, described the occasion as a significant achievement for Makerere University and Uganda’s health sector.
“Today is a very important occasion for the College of Health Sciences, and indeed the health sector in Uganda,” he said, noting that the fellowship was established to develop highly skilled specialists capable of responding to increasingly complex healthcare needs.
Prof. Kirenga emphasized that Uganda’s changing disease patterns, increasing life expectancy, and growing demand for specialized healthcare services have created an urgent need for super-specialized training programmes. He challenged the graduates to use their newly acquired knowledge and skills to improve newborn health outcomes and save lives.
Addressing Uganda’s Neonatal Health Burden
Presenting an overview of the fellowship programme, the Head of the Department of Paediatrics and Child Health, Prof. Victor Musiime, highlighted the urgent need for specialists in neonatal care.
He noted that neonatal deaths, those occurring within the first 28 days of life, remain one of the leading contributors to child mortality in Uganda. The country continues to face a shortage of professionals with advanced skills in neonatal care, research, leadership, and advocacy.
“The demand for neonatologists remains extremely high,” Prof. Musiime explained, adding that the Ministry of Health envisions deploying neonatologists to regional referral hospitals and other health facilities across the country.
The fellowship programme was established to build a critical mass of neonatologists, strengthen care for high-risk newborns, develop expertise in advanced neonatal procedures, and produce leaders and advocates for newborn health.
A unique feature of the programme is its strong clinical apprenticeship model, complemented by international placements at leading institutions, including Yashoda Hospital in India and Aga Khan University Hospital in Nairobi, Kenya.
Ministry Commits to Expanding Neonatal Services
Representing the Ministry of Health, Commissioner for Maternal and Child Health, Dr. Richard Mugahi, congratulated the graduates and commended Makerere University and its partners for establishing the fellowship programme.
Dr. Mugahi revealed that the five graduates join another five neonatologists already serving in Uganda, bringing the country’s total number of neonatologists to ten. He described the locally trained fellows as a critical addition to Uganda’s healthcare workforce.
“The Ministry’s vision is to have a neonatologist at every Regional Referral Hospital,” he said, adding that Uganda aims to have at least 14 neonatologists by 2030.
He further outlined government plans to strengthen newborn care through the establishment of specialized neonatal care units at different levels of the health system, ranging from Health Centre IVs to Regional Referral Hospitals and super-specialized facilities such as Mulago Specialised Women and Neonatal Hospital.
Dr. Mugahi assured the graduates that the Ministry of Health is investing in equipment and infrastructure to support advanced neonatal services and pledged to advocate for improved career progression pathways for super-specialized health professionals.
Makerere’s Commitment to Advanced Medical Training
Representing the Vice Chancellor, the Deputy Vice Chancellor (Finance and Administration), Prof. Henry Alinaitwe, congratulated the fellows and their families on the achievement.
He praised the College of Health Sciences for its contribution to national development and noted that programmes such as the Perinatal and Neonatal Medicine Fellowship enhance Makerere University‘s position as a leader in knowledge generation and societal transformation.
Prof. Alinaitwe paid tribute to the graduates’ families, particularly their spouses and children, for supporting them through the demanding years of specialist training.
“The work you do is truly priceless,” he told the fellows. “The contribution you make to humanity is immeasurable.”
Graduates Hailed as Future Leaders in Newborn Health
In attendance were the director of Mulago Specialized Women and Neonatal Hospital, Dr. Sam Ononge, Deputy Director Mulago Referral Hospital, Dr. John Sekabira, Dr. Mary Nyanzi from Kawempe Referral Hospital, Sr. Dr. Assumpta Nabawanuka, the Director of St. Francis Hospital Nsambya, Dr. Irene Atuhaire from Seed Global Health Uganda and Ms. Ritah Akankwasa from ELMA Philanthropies Services, who partnered with the college in training the fellows.
The training partners described the graduates as pioneers who had demonstrated exceptional resilience and commitment throughout the rigorous training programme.
They applauded their contributions to patient care, teaching, mentorship, and supportive supervision, noting that their work had already contributed to improvements in maternal and newborn health services in Kampala and other regions of Uganda.
“As Kawempe National Referral Hospital, we have been privileged to witness your growth, not only as clinicians but also as leaders and advocates for newborn health,” Dr. Nyanzi said.

For most people, the thought of death evokes grief, fear, or loss. But at Makerere University‘s College of Health Sciences, death became a lesson in gratitude, service, and humanity as students, faculty, and health professionals gathered to honour a unique group of teachers, individuals who continued to educate future doctors long after their passing.
At the Second Cadaver Commemoration Ceremony, on June 11, 2026, organized by the Makerere Students’ Anatomy Society, candles flickered softly as students paid tribute to what they fondly call their “silent teachers”, the human bodies that make it possible for medical students to learn anatomy and develop the skills that will one day save lives.
Standing before fellow students and guests, Chairperson of the Makerere Students’ Anatomy Society, Joseph Mwera, reminded the audience that the ceremony was not about mourning the dead.
“Today, we gather not only to remember those whose bodies have contributed to medical education but also to celebrate their lives,” he said. “Their legacy continues to inspire and serve humanity even after death.”
For many medical students, the anatomy laboratory is where they first encounter the reality of the profession they have chosen. Behind every lesson on muscles, nerves, blood vessels, and organs is a person who once lived, loved, worked, and contributed to society.
That reality was brought to life by the keynote speaker, Rev. Prof. Dr. Samuel Luboga, a surgeon, anatomist, and priest who spent nearly four decades teaching anatomy at Makerere University.
Reflecting on his own days as a medical student, Prof. Luboga recalled spending long hours in the anatomy laboratory after his classmates had gone home, studying human anatomy in detail.
Many people wondered whether he was afraid to spend so much time among cadavers.
His answer was simple.
“These men and women had lived productive lives. They had raised families, served their communities, and contributed to Uganda’s development. Even in death, they continued to teach us the science and art of medicine. They had earned my admiration, my respect, and my gratitude.”
His remarks resonated deeply with the students in attendance.
In a society where discussions about death and body donation remain sensitive, Prof. Luboga challenged participants to view the individuals in anatomy laboratories not as lifeless remains but as people who continue to contribute to humanity through education.
“The silent teachers before us today made learning possible,” he said. “The impact of their contribution is reflected in the doctors you have become and those you are yet to become. It is reflected in the countless patients you will treat and the innumerable lives you will save.”
Legal framework to guide body donation
The ceremony also sparked important conversations about the future of anatomical education in Uganda.
Head of the Department of Anatomy, Prof. Elisa Mwaka, highlighted the need for a national legal framework to guide body donation and anatomical research. While anatomy training in Uganda has traditionally relied on unclaimed bodies obtained through hospitals, he noted that many countries are increasingly embracing voluntary body donation programmes.
According to Prof. Mwaka, building public trust will be essential if Uganda is to establish a sustainable body donation programme.
“We must help the public understand how human bodies contribute to medical education, how they are treated with dignity, and how appropriate legal safeguards can protect donors and their families,” he said.
He revealed that discussions are already underway to develop an Anatomy Act that would provide a modern legal and ethical framework for the use of human remains in medical education and research.
Representing the Deputy Vice Chancellor (Academic Affairs), Prof. Julius Kikooma described the ceremony as much more than an academic event.
“Behind every competent healthcare professional stands an invaluable source of learning that often remains unseen and unheard,” he said. “These individuals taught us without speaking a single word. Though they are no longer able to communicate, their contribution continues to educate, inspire, and shape future generations of healthcare professionals.”
He commended the medical students for organizing what remains the only cadaver commemoration ceremony of its kind in Uganda, noting that the initiative reflects the values of compassion, professionalism, and respect for human dignity that are at the heart of medicine.
The event concluded with recognition of past and present leaders of the Department of Anatomy whose contributions have shaped anatomical education at Makerere University over the decades. Students also honoured exceptional educators who have inspired generations of future health professionals.
Yet the most powerful tribute of the day was reserved for those who could not be present to receive awards or applause.
The silent teachers
Individuals whose names may never appear in textbooks, whose stories may never be fully known, but whose gift continues to echo through hospital wards, operating theatres, and communities across Uganda.
Every doctor trained, every surgery performed, and every life saved carries a small part of their legacy.
And for one day at Makerere University, students paused to say the words that are rarely spoken aloud: Thank you.
