Experts have urged urgent action to mitigate the health risks of climate change. The 2023 global conversation, on Climate Change and Health highlighted the need for transformational action in every sector to protect people’s health from climate change.
Held on September 5, 2023 the virtual seminar, organized by the Centre of Excellence for Sustainable Health (CESH), a collaboration between Makerere University and the Karolinska Institutet that aims to increase capacity and spur action to advance the agenda for sustainable health drew over 230 attendees from all over the world. It placed emphasis on mitigating the effects of extreme weather, such flooding.
In its 2023 report, the Intergovernmental Panel on Climate Change (IPCC) notes that global terrestrial, freshwater, and ocean ecosystems have already been affected by climate change, along with the associated losses and costs. It predicts that heavy rainfall and flooding events are expected to worsen and occur more frequently in the majority of regions of Africa, Asia, North America, and Europe by 1.5°C global warming (high confidence).
The 2023 IPCC report identifies barriers that prevent people and society from implementing climate-resilient behaviors. Financial limitations, conflicts with the SDGs, inequalities, institutional, economic, and social hurdles, as well as dispersed strategies, are a few of these. The panel equally agree that if global warming exceeds 1.5 °C and the SDGs are not adequately progressed, chances for climate-resilient development would be considerably more limited.
Now, during the seminar, the panel, by consensus agreed that climate change is critical citing that such conversations on critical factors in relation to the climate and health crisis are not only timely but necessary.
Climate change impacts the social determinants of health, which include excellent health and wellbeing, by causing decreased food output, low fishing yields, flooding, and infrastructure damage, according to Daniel Helldén, a PhD student at KI Department of Global Public Health.
“The future emission scenarios are dire. What is becoming more and more clear is that climate change is a generational issue. Children born today will continue to bear the biggest burden of climate change impact,” said Helldén.
Dr. Mugume Isaac Amooti, the Director of Weather Forecasting Services at the Uganda National Meteorological Authority (UNMA), emphasized the importance of considering both long-term averages and unprecedented weather events driven by climate change. These events are thought extreme only when they exceed past records. He noted for instance that in Uganda; “The widespread flooding brought on by heavy and frequent precipitation is what we are seeing in Uganda, particularly in the cities. However, we are witnessing heat waves and cold waves at different times of the year.”

Although there isn’t a clear pattern in Sweden’s precipitation, Dr. Johanna Sörensen of Lund University in Sweden said that forecasts suggest that rainfall may increase by the end of the century. Given the flooding problems that already present, this, she says is something to worry about. “Flooding is increasing not only because of climate change but also even more that we construct the cities more densely and we construct buildings and industries on lowly areas that we used not to do in the past which is of course not a good idea.”

Dr. Tamer Rabie, a lead health specialist at the World Bank Group, notes that risks are amplified by climate change, which therefore has an intensified negative impact. He points out, for instance, that in order to comprehend how climate change and changes in temperature and precipitation patterns will affect health, it is critical to view climate change as a risk multiplier.

Dr. Tamer, also the architect of the World Bank’s global Health-Climate and Environment Program (H-CEP), underscored three pathways through which climate change impacts health: direct effects, indirect effects, and those mediated by ecosystems. Some of the direct pathways include issues like increased temperatures likely to lead to heat waves, heat-related illnesses, worsened non-communicable diseases, and increase in the risk of events like traumatic injuries.
According to Dr. Tamer, ecosystem-mediated risks include vector-borne diseases (like Malaria and Dengue), foodborne illnesses, and waterborne diseases (like Cholera). These risks are closely tied to how health outcomes are influenced by the ecosystem. Additionally, indirect health impacts encompass mental health due to population displacements, as well as malnutrition resulting from shifts in food production and overall food systems.
“We have done estimates in the World Bank that show that extreme weather events and climate change will lead to pushing nearly 132 million people into extreme poverty by 2030. If you look at the health impacts within those figures and the main drivers, we are seeing that nearly 44 million out of those 132 will be pushed into extreme poverty by 2030 if we don’t take any action today,” Dr. Tamer.
According to Dr. Tamer, the World Bank has conducted climate and health vulnerability assessments specifically looking at the cost of inaction moving into the 2030s and 2050s using information that relates to malaria, dengue, diarrhea, stunting in children, heat related illnesses, floods, among others.
“What we are seeing is that on average, countries will be losing anywhere between 1-5% of their GDP as a result of not really addressing the climate crisis, not being able to address these impacts that we are talking about, and obviously not investing enough into the health systems to be able to be more resilient,” Dr. Tamer noted during the webinar.
According to Dr. Sara Gabrielsson, an Associate Senior Lecturer in Sustainability Science at Lund University’s Centre for Sustainability Studies (LUCSUS), addressing immediate health risks involves containing flooding, which is just one aspect of climate change-related challenges like sea level rise and drought.

She highlights the connection between various deadly diseases like dengue, typhoid, trachoma, and cholera among others to this issue. During a crisis like flooding, treatment for these diseases she notes often takes a backseat due to the overwhelming health burdens that arise.
“There is death from drowning or direct injury from debris in these very storm surges, but then we also have the issue of just water sitting, waiting in water for longer periods, leading to lots of infections, urine-tract infections, vaginal infections, skin diseases, hypothermia, lots of those kinds of things, but also vector-borne diseases, and especially malaria, which is, of course, one big thing here,” Dr. Gabrielsson opines.
She adds that flooding brings problems like contaminated drinking water, leading to chronic diarrhea and malnutrition. Additionally, damaged sanitation facilities force people into open defecation, exposing them to harmful bacteria and further risk of chronic diarrhea.
“These immediate health risks are just the beginning. Moving into long-term risks, flooding severely impacts the availability of clean water for basic hygiene. As we’ve learned from COVID, hygiene is paramount for health. Insufficient handwashing and personal hygiene can breed disease. We need proper hygiene for preparing food, tending to babies, managing menstrual health, and more. Without it, there’s increased exposure to harmful bacteria, compounded by the use of inadequate sanitation systems, resulting in outbreaks of various diseases,” observed Gabrielsson.
Way forward
Dr. Sörensen, from a Swedish standpoint, proposes proactive steps to mitigate flooding. These include slowing down water flow, discouraging construction in flood-prone zones, and avoiding building in areas prone to heavy rain. She points out that in cities like Mumbai and Gothenburg, there has been a concerning trend of construction in flood-prone regions. Dr. Sörensen emphasizes the importance of adapting solutions for creating greener, more sustainable cities. “In China, they call it a sponge city. It’s like a sponge—you fill it up with water during rainfall and then use it later for various purposes. Utilizing vegetation and water storage helps retain water and slow down its flow in urban areas. Green spaces in cities are crucial for health, well-being, and providing shade, especially during heatwaves,” she says.

In Uganda, Dr. Mugume notes that the government has invested in weather monitoring infrastructure, including the three weather radars, which are strategically spread across the country to enable UNMA to monitor weather at any part of the country.
“With this technology, we can now offer more precise and timely services, ensuring our communities respond effectively. Weather and climate forecasts range from hourly to seasonal projections. Shorter forecasts tend to be more accurate, although longer ones still fall within manageable limits. For instance, our seasonal forecast accuracy in Uganda is at 90%, aligning with National Development Plan 3. We collaborate with development partners to fine-tune these forecasts.”
For Dr. Gabrielsson, preparedness is key, especially for the 2.2 billion people worldwide relying on sanitation systems, many of whom live in rapidly urbanizing areas and unplanned settlements.
Unfortunately, these systems often lack proper management, leading to health risks. In urban settings, she says, the spread of sludge from these systems can have widespread health implications. To address this, there’s a pressing need to prioritize climate-resilient sanitation systems. Historically, the sanitation sector has been under-prioritized, resulting in insufficient funding and political attention. Without a one-size-fits-all solution due to diverse living habits, cultural considerations become paramount. A gender-responsive approach is crucial, as women are primarily responsible for WASH (Water, Sanitation, and Hygiene) practices.

“It involves recognizing the unique needs of different groups, such as refugees, the elderly, disabled individuals, children, and menstruating individuals. Climate-resilient wash infrastructure requires community responsibility, government policy, and financial support. For instance, in flood-prone areas like the Amazon Basin, sanitation facilities are designed to align with local livelihoods, incorporating features like composting latrines that produce manure for farming and collecting rainwater for handwashing. This approach ensures environmental safety and sustainable practices,” she observes.
Dr. Gabrielsson emphasizes the importance of cultural acceptance in encouraging people’s dedication to upholding basic sanitation and hygiene practices, particularly in the face of flooding. “Another example I presented is a UNICEF-supported toilet in Bangladesh. It’s elevated with precast concrete rings to prevent flooding, sealed with concrete mortar for contamination prevention, and reinforced to withstand heavy rain and wind. This design was developed in close consultation with local communities, ensuring cultural acceptance and affordability. The goal is to create facilities that people actually want to use, which is why it’s crucial to integrate natural and social sciences for effective solutions.”
The World Bank has substantially supported action on climate change, including both adaptation and mitigation initiatives. Dr. Tamer says over $2.2 billion has been set aside as of today for climate-related health interventions, especially in South Asia and sub-Saharan Africa. Significant assistance has also been given to assist tiny island states in managing the effects of climate change, particularly extreme events.
In Yemen, the World Bank has sponsored efforts to put in place electronic early warning systems for real-time health data and policy response due to outbreaks of diseases including cholera and malaria. In Madagascar, the World Bank has funded work combining climate and nutrition programming. The World Bank worked with the government of Ghana to create long-lasting vaccine delivery networks.

Makerere Medical Students Honour Their ‘Silent Teachers’
Published

June 12, 2026
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.

The silent teachers: why body donation matters

By Assoc. Prof. Erisa Mwaka and Joyce Nabukalu-Kiwanuka
In every hospital, there is a moment when knowledge becomes a matter of life and death. A doctor must know where to place an incision, how to avoid damaging major organs, how to identify a nerve, how to deliver a baby safely, how to interpret a scan, or how to explain disease to a worried family. That knowledge does not begin in the operating theatre, it begins much earlier, in the anatomy laboratory.
For generations, the study of the human body has been the foundation of medical education. The regular use of human bodies for medical training purposes began in the late Middle Ages and spread during the 18th and 19th centuries. Initially, anatomists depended on gallows, poor houses, mental asylums, or jails as sources of bodies. However, the 1960s and 1970s saw the emergence of wilful body donation. Before students become doctors, surgeons, dentists, nurses, physiotherapists, radiographers, and other health professionals, they must first understand the human body in its real form. They must learn not only from books and diagrams, but from the body itself. This is why cadavers, though silent, remain the most important teachers in medical education. In simple terms, a cadaver is a dead human body used by health professions students to study anatomy; and Anatomy is the study of the physical structure and organization of the human body, both at macroscopic and microscopic levels.
As the Department of Anatomy at Makerere University College of Health Sciences prepares to commemorate the “silent teachers” whose bodies are used for medical education on June 11, 2026, Uganda is invited to reflect on a subject that is rarely discussed in the public domain, willed body donation. Body donation simply means a person willfully donates their body for educational purposes after death, and consent to it in life. This is a sensitive topic, but it is also a deeply human one. It touches our beliefs, families, culture, understanding of death, and responsibility to future generations.This commemoration ceremony is not symbolic but, it is a public statement that the contribution of silent teachers is sacred, educational, and deeply appreciated.
To donate one’s body after death is not an ordinary decision; it is an altruistic act of extraordinary generosity. It is a final gift to society. It allows health professions students to learn and appreciate the human body before they treat living patients. Cadavers are therefore not “specimens”, they are silent teachers and partners in medical education who continue to serve humanity even after death. Learning anatomy using a cadaver helps students to understand and appreciate the complexity of the human body, appreciate its natural variations, and develop the confidence and competence needed to serve the public. Students are also taught laboratory etiquette that emphasises dignity, empathy, and utmost respect for the cadavers, which attributes they carry into the clinical years when they interface with hospital patients.
In Uganda, where the demand for health workers continues to grow, medical education must be strengthened at every level. Our country needs well-trained doctors and health professionals who can serve in hospitals, health centres, universities, research institutions, and communities. But good training requires good teaching resources. One of these resources are the silent teachers who never complain, but impart immeasurable knowledge to future health professionals. Modern technology has introduced many useful tools into medical education. Students can now learn from videos, computer applications, digital images, plastic models, three-dimensional models, and virtual platforms. These tools are important and should be embraced, however, they cannot completely replace learning from the real human body. A cadaver teaches what a diagram cannot fully show; the true position of organs, the texture of tissues, the relationship between structures, and the natural differences that exist from one person to another. More importantly, cadaver-based learning teaches respect. It reminds students that medicine is not simply a technical profession, it is a calling rooted in human dignity. The first lesson students learn in the anatomy laboratory is that the body before them belonged to a person who had a name, a family, a story, and a life. That lesson shapes how they later treat patients.
Currently, most, if not all universities in Uganda, and similar settings in Africa use unclaimed bodies for learning Anatomy. The use of cadavers in Uganda is governed by the Penal Code (Anatomy Rules) of 1957 that permits public hospitals to transfer bodies unclaimed for at least 14 days to a medical training institution like Makerere University. Unfortunately, these cadavers are used without the consent of the deceased because most of them are unknown and with no known relatives to claim them. Many opponents to the use of unclaimed bodies opine that the practice is unethical. There is a global push toward ethical use of cadavers in medical education, where a person consents and bequeathes his/her body for medical education when still alive. For this practice to be sustainable, there is a need for a well regulated body donation program. Unfortunately, the concept of willful body donation is still not well understood by many people, and neither has it been a topic of public debate. Further, there are lots of myths surrounding death and dying in Africa, including Uganda that have hindered the establishment of successful body donation programs. Willingness to donate bodies for medical education is however, influenced by several factors including cultural and religious beliefs, respect for the dead and the need to fulfil burial rites, fear for mutilation and disrespect, to mention a few. These concerns are real and should not be dismissed. But they should be addressed with accurate information, openness, and utmost respect.
It is important to understand that body donation does not mean that a person is forgotten. On the contrary, it creates a legacy. A body donor may teach hundreds of future health professionals, in that way, one person’s final act of generosity can touch and save countless lives. This is kind of patriotism is largely unkown in Uganda and we do not speak about enough. We often talk about serving our country through leadership, business, farming, teaching, parenting, or community service. But there is also service beyond life. Body donation is one way of saying: “Even when I am gone, let me contribute to the health of my people.”
Currently, Uganda now has more than 15 universities training medical students and the demand for cadavers for learning anatomy is on the rise. Actually, the supply of cadavers cannot fulfil the demand, and medical educationists need to find alternative source of cadavers. Wilful body donation is the answer.
Uganda needs a national conversation on body donation. There is a need for deliberative public engagement involving various stakeholder including the public, religious and cultural leaders, civic leaders, the media, educationists, health professionals, medical training institutions, etc.
This commemoration ceremony will involve inter-denominational prayers for the silent teachers, and a reflection of their contribution to healthcare in Uganda. We hope this ceremony will provoke public debate on a subject that is hitherto considered a taboo by many. We talked about some of these issues last year, in the first ever such ceremony in Uganda, and have received several requests for more information on the procedure for donating one’s body for teaching purposes upon death. Like President Obama’s said, “yes we can”, an the dialogue starts from you and me. You are all invited for the commemoration ceremony at 9.00 am on June 11, 2026, at the Makerere University School of Public Health auditorium on main campus.
To donate one’s body is to give a final lesson, a final service, and a lasting gift to the nation.
