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.

Makerere-Incubated Safe Bangle Technologies Wins Prestigious World Summit Award for Innovation Against GBV
By Joseph Odoi
In a groundbreaking achievement, SafeBangle Technologies, an innovation incubated at Makerere University, has won the prestigious World Summit Award 2025 for its groundbreaking contribution to the fight against gender-based violence (GBV) in Africa. This remarkable honor comes in recognition of the development and implementation of a real-time domestic violence reporting bracelet.
The award was presented to the SafeBangle team that was represented by Saul Kabali, Messach Luminsa, and Janet Christine Nabaloga from SafeBangle Technologies at the WSA Global Congress in Hyderabad, India, where Uganda’s innovation potential was proudly showcased on a global stage.
The award was conferred in the Inclusion & Empowerment category for Safe Bangle’s cutting-edge solution; a wearable safety bracelet designed to address the pressing challenge of gender-based violence (GBV) across Africa.
The SafeBangle is a smartwatch-like, real-time domestic violence reporting bracelet that allows users to send SMS alerts via a single button press. Its core mission is to create a safer, more secure environment for women and children in Africa through innovative, affordable tech solutions.
According to Saul Kabali and Messach Luminsa, the innovators behind SafeBangle from SafeBangle Technologies, hosted at the Resilient African Network Lab. This award is very timely and a recognition that cements the importance of community rooted technology.
The team further stated that ‘’This award is a powerful affirmation of our mission and refuels our commitment to empowering Ugandan women and girls through innovation and technology. It influences our next steps by opening doors to new partnerships, increasing our credibility, and accelerating efforts to scale the SafeBangle nationally. We’re now more equipped to positively impact the daily lives of Ugandan women and girls through our SafeBangle bracelet.
To further the innovation, the team has called upon government to support the Safe Bangle Innovation
‘’Governments can support us by providing funding, facilitating policy support, and creating collaborative platforms for innovation. NGOs can help with grassroots outreach, and connect us to potential donors and funders interested in solving Sexual and Gender Based Violence amongst vulnerable communities; and tech partners can enhance scalability through infrastructure, data insights, and capacity building.
Moving forward, the team emphasized the importance of uniting innovation, partnership, and purpose to scale impact. “As we empower communities, invest in local solutions, and promote collaboration, we can transform how technology protects and uplifts women and girls across Uganda,” added the award-winning team.
The Story Behind the Safe Bangle Bracelet Innovation
According to the Safe Bangle innovators Saul Kabali and Messach Luminsa , ‘’The inspiration behind SafeBangle came from a deeply personal place. ‘’We heard countless stories of women who couldn’t call for help during moments of danger. We were deeply affected by the story of Aisha, a young woman in a rural village who was attacked while walking home alone at night. With no way to call for help, she felt helpless and vulnerable. This incident made us realize the critical need for immediate reporting alert tools, accessible to women like Aisha. We knew technology could play a crucial role and this incident awakened a strong desire in us to create a solution’’
To Makerere University School of Public Health’s Dr. Juliet Kiguli, who collaborated closely with the team during the rollout of the bracelet, this award is a vote of confidence in the work of Makerere University, whose core function focuses on teaching, learning, community engagement, research, and innovation, all contributing to the university’s efforts in addressing domestic violence.
‘’The award-winning innovation stems from the findings of a longitudinal study led by the Makerere University School of Public Health.
While carrying out a study after the Covid-19 Pandemic, we identified gaps when it comes to reporting and response to Gender Based Violence (GBV) among women in informal settlements. Therefore, we used to incorporate the SafeBangle intervention to solve the problem of lack of affordable and immediate reporting mechanisms for violence using a bracelet that reports violence in real time
We’re excited about the progress so far, and with this recognition, we hope that more like-minded partners will join us to scale this initiative and ultimately help make the world a safer place for all.” Added Dr Kiguli of the Safe Bangle innovation potential
The research team, comprising Dr. Juliet Kiguli (Principal Investigator), Dr. Roy Mayega (Deputy Chief of Party, RAN), and Dr. Agnes Nyabigambo (Study Coordinator), piloted the bracelet under the PEER (Partnerships for Enhanced Engagement in Research) program with support from USAID and the National Academies of Sciences.
A consortium of partners, including SafeBangle Technologies, Makerere School of Public Health/RAN , the Medical College of Wisconsin, and Somero Uganda, implemented the rollout of the Domestic Violence Real-Time Reporting Bracelet. The initiative was supported by USAID and the National Academy of Sciences in Washington, DC. Key contributors to the project included Dr Juliet Kiguli Roy Mayega from Makerere University School of Public Health, Dr. Kelly Robbins, Dr. Lina Stankute-Alexander, Dr. Brent Wells, Dr. Melissa Trimble, and Uganda’s Dr. Gloria Kasozi at USAID. Wisconsin Madison Medical University’s Prof. Julia Dickson-Gomez was also a collaborator.
In terms of the acceptability of the SafeBangle innovation as a solution to GBV, the team has piloted the technology with more than 1,000 users, resulting in a 63% reduction in response times
During the event, SafeBangle Team participated in the “Equity by Design” panel, sharing insights on inclusive technology development with global experts including Dorothy Gordon, Abhishek Singh from India’s Ministry of Electronics and IT, Baroness Beeban Kidron, and representatives from UNESCO and WE Hub.

A Humble Petition from the Marabou Storks of Kampala to His Excellency, President Yoweri Kaguta Museveni
Your Excellency,
We send you warm greetings from the skies above Kampala — from your old, bald-headed friends, the Marabou Storks, or as we are fondly called, the Kalooli. We are not the prettiest of birds, with our wrinkled faces, hunched shoulders, and sharp beaks, but we carry an important duty. Where others see waste and decay, we see purpose. We are nature’s cleaners, recycling what would otherwise rot and cause harm.
Some count us among Africa’s “Ugly Five,” alongside hyenas, vultures, wildebeests, and warthogs, but we take no offense. Beauty was never the Creator’s mission for our mission, but service was. We glide quietly between life and death, keeping the balance, cleaning the mess, and doing the work that must be done.
Today, we come to you not with complaints, but with a plea for partnership, to protect our shared home and ensure a cleaner, healthier Uganda for all. We still remember the day in 2008, Mr. President, when you gave the Uganda Wildlife Authority and the Kampala Capital City Authority instructions to “kindly relocate us” from the esteemed grounds of State House, Nakasero. We don’t harbor angry feelings. Truly. We realized back then, as we do now, that not everyone finds our odd looks or the noble scent that naturally results from a lifetime of cleaning your lovely nation appealing.
Your Excellency, we are modest. And forgiving. We maintained our composure even when we were discussed in Parliament in 2020, when honorable members referred to us as “health threats” and asked that we leave the Parliament gardens. We birds, after all, literally have thicker skin!
We are better citizens now. Thanks to Makerere University‘s kind hospitality, we have discovered a new haven. We express our deep thanks to Vice Chancellor Professor Barnabas Nawangwe for preserving the ancient trees, the very canopies that now provide us with protection, generation after generation. Students here lovingly refer to us as “the real professors of Makerere,” observing us as we keep a watchful eye on campus life with our sage, steady gaze. Some people think it’s a blessing to see a Kalooli before an exam. We take selfies with other people. We have kind of turned into little celebrities, sir. We appreciate the tranquility, love and peace you provided, with your comrade freedom fighters. They bring uhuru to these trees, and our kids pray for you every day for more life.
However, we come before you today not just to reminisce, but to raise important concerns not for ourselves alone, but for the survival of Uganda’s fragile ecosystem.
We are concerned about the growing crisis in waste, plastics, and environmental decay.
Your Excellency, you are a man who loves numbers. Allow us to present some:
- 768 metric tons — that is the amount of food waste produced DAILY in Kampala alone.
- 65% to 79% of solid waste in Kampala landfills consists of food waste.
- The dairy industry in Uganda loses $23 million annually from waste alone, according to the Food Rights Alliance.
- 135,804 tons of plastic waste generated in the Kampala Metropolitan Area recently.
- 42% of that waste remains uncollected, leading to clogged drains, flood risks, pollution of wetlands, and of course, diseases.
- Shockingly, 10% of this waste ends up in Uganda’s precious water systems!
Your Excellency,
It might surprise you but it’s true. Between 2018 and 2021, Uganda produced 12,330 tons of recycled polyethylene (rPET). And that’s not all conservative estimates predict a 91% increase in production between 2022 and 2025, should imports stay the same.
Mr. President, we Marabou Storks have served loyally as your unpaid, unsung environmental officers. While your citizens discard waste carelessly, we fly across the city, scavenging, sorting, and managing organic decay. We are your frontline solid waste managers, yet without uniforms, pensions, or even a simple “thank you.”
We join you in mourning the tragic loss of life that occurred at Kiteezi Landfill. We experienced devastation because the birds that live there consider that place their territory. We directly observed your people’s struggle to survive while they navigated hazardous unstable waste piles. Our deepest condolences go out to the families who lost loved ones and to every Ugandan citizen. The disaster served as a harsh reminder that waste mismanagement impacts people directly beyond just environmental concerns. Working together as environmental custodians we ask you to take action to prevent more deaths from occurring beneath waste mountain piles.
Just for context, Mr. President, since you fondly like science, here is the scientific truth about us
You may recall Dr. Derek Pomeroy and Mr. Michael Kibuule, distinguished researchers at Makerere University, who in 2021 published the history of our kind in Uganda. They noted:
- Over 1,200 nesting pairs once graced Kampala city alone.
- Over 800 Marabous nested at Makerere University.
- Uganda likely hosts the largest urban colony of Marabou Storks in the world.
Dr. Pomeroy and Kibuule should receive Katonga medals because we recognize their devotion to us. They have loved us. Dr. Pomeroy first came to Uganda in 1969 to work in Makerere University‘s Department of Zoology. He developed deep affection for us and demonstrated excellent understanding. He has written affectionately about us. He knows we are innocent. Dr. Pomeroy maintains his affiliation to Makerere University while conducting independent research as both a Zoologist and an ecologist.
Mr. President, in the beginning, our existence was in the untamed savanna. We transitioned to urban areas alongside human development to assist with cleanup duties rather than to create any disturbance. We came to clean up the areas where you discarded bones and waste. Ronald Norman Magill stated that despite being part of Africa’s “Ugly Five,” we remain crucial to ecosystems because our simple and gritty nature is what makes us indispensable. Our role includes feeding on dead animals and decomposing matter to prevent diseases and sustain soil health through silent and selfless recycling of life.
Your Excellency, here are our humble pleas to you, Our President
- Please urge your people to plant trees.
Our homes are disappearing completely. Sky scrapers are popping up everywhere we used to patch. Your Excellency, we merely ask that you recognize our role and protect our habitats; we are not opposed to development. In order to locate nesting sites, we now have to travel a considerable distance between Kiteezi, Lubigi, and the University. For all creatures, feathery, four-legged, and two-legged—healthy trees translate into richer soils, cleaner air, better rainfall, and cooler cities. - Please strengthen plastic waste management.
Your laws Mr. President, the 10-Year Restoration Plan, the National Environment Act 2019, and the Extended Producer Responsibility rules are all positive steps, but laws that do nothing are just as useful as wings on a tortoise. Please advocate for implementation, particularly in the areas of public education on responsible dumping and enforcement. We implore you to encourage your people to stop illegal dumping, sort their waste, recycle, and treat the environment as a gift rather than a trash can. - Please invest boldly in waste infrastructure.
Your Excellency, - If Parliament can enjoy a small patriotic “thank you” of the legendary “100 silver coins” for safeguarding peace, surely a few crumbs can reach us, the Marabou Storks; Kampala’s tireless, unpaid sanitation workers, as a token of national gratitude. Imagine what a few billion shillings for KCCA, for trucks, bins, and civic education could achieve. A cleaner Kampala would mean less wandering for us and less embarrassment for you when tourists meet our noble, bald-headed selves. At least then, we would feast in dignity, not after cross-country marathons over scattered rubbish.
- Support Community Environmental Heroes.
Students, youth, schools, churches, and communities are already doing cleanup drives. Support them with grants, incentives, recognition, and encouragement. Empower a new generation of eco-warriors.
Mr. President, we, Marabou Storks are no longer the nuisance you once sought to relocate.
We are living proof that resilience, adaptation, and hard work can co-exist even in a changing, urbanized world.
All we ask now is for you and your government to join wings with us, birds and humans alike to clean up Kampala, to green Uganda, and to create a legacy that future generations will bless you for.
Let us work together, so that Uganda shines not under mounds of waste, but under canopies of trees, rivers flowing freely, and skies where even the humble Kalooli can soar proudly.
Yours sincerely,
The Marabou Storks of Kampala
