Global Conversations: Climate Change Multiplies Health Risks, A Call to Action on Extreme Weather Effects
By Davidson Ndyabahika, Johanna Blomgren and Julius T. Mugaga
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 Researchers Find Psychological Therapy Effective in Improving Diabetes Care in Uganda
By Nelson Bahati
Researchers from Makerere University‘s School of Psychology have found that psychotherapy intervention can improve the well-being of adults living with Type II diabetes mellitus, opening the door for integrating psychosocial support into diabetes care in Uganda.
The findings were disseminated on 16 June 2026 during a research dissemination workshop held at the Physiology Lecture Theatre at the College of Health Sciences, Mulago Hospital.
Led by Professor Peter Baguma, the study titled “The Effectiveness of Cognitive Behavioural Therapy for Diabetes Distress, Depression, Health Anxiety, Quality of Life and Treatment Adherence among Adult Patients with Type II Diabetes Mellitus” investigated whether Cognitive Behavioural Therapy (CBT), a psychological treatment that has proven effective in Western countries, could also work in the Ugandan context.
Presenting the findings, Professor Baguma said the study was motivated by the growing burden of diabetes and the psychological challenges that often accompany the disease but are rarely addressed in routine healthcare.
“Diabetes affects many people in Uganda and across the world. It kills, and those who live with it face many challenges. While psychological interventions have been developed and applied in the Western world, we did not know whether these approaches could work in Uganda. That is why we decided to undertake this study,” he said.
He explained that Cognitive Behavioural Therapy focuses on changing negative thoughts and behaviours that affect people’s wellbeing and ability to manage chronic illnesses.
The researchers sought to determine whether CBT could reduce psychological distress among diabetes patients and improve treatment outcomes.
The controlled study involved 200 adult participants with Type II diabetes mellitus. One hundred participants received the CBT intervention while another 100 formed the control group. Participants in the intervention arm attended eight counselling sessions over four months, with each session lasting between one and one-and-a-half hours.
The therapy covered several modules, including psychoeducation on diabetes, cognitive restructuring, medication adherence, problem-solving, coping strategies, physical exercise, relaxation techniques and strategies for maintaining treatment.
According to Professor Baguma, the findings showed that psychotherapy significantly improved participants’ wellbeing.
“The group that received the intervention experienced reduced stress levels and lower blood sugar levels compared to those who did not receive the therapy. We conclude that CBT is effective and should be adopted as part of diabetes care,” he said.
The study also yielded another important discovery.
“We have discovered that CBT as practised in the Western world is somewhat narrow. Their manual contains only eight elements. In Africa, we found that three additional components are necessary: effective communication between patients and health workers, goal setting, and instilling hope among patients. We call this African CBT,” Professor Baguma explained.
He added that the findings had also revealed the need to incorporate psychosocial care into the management of chronic illnesses and to train healthcare workers to address the psychological dimensions of disease.
Professor Andrew Marcel Otim, one of the co-investigators and founder of the Uganda Diabetes Association, said the study had brought to the fore an aspect of diabetes care that has long been neglected.
“There have been many efforts to address the physiological effects of diabetes, but we have largely ignored the psychological part of the disease. Yet the psychological aspect is huge,” he said.
He added that, diabetes management should go beyond medication but rather intergrate other components of care.
“Education, nutrition, exercise and self-monitoring are extremely important. Even simply knowing what to do is a very powerful intervention. Psychological distress and depression can increase blood sugar levels, so we need to help patients remain calm and hopeful,” he said.
Drawing from his experience as a clinician and educator, Professor Otim encouraged people living with diabetes to embrace physical activity.
“I tell my students and my patients to put on some music, dance, sweat and enjoy themselves. Nutrition, education and exercise remain central to managing diabetes.”
Dr. Wilber Karugahe, a counselling psychologist at Makerere University‘s School of Psychology and one of the co-investigators, said the findings demonstrate the need to integrate psychological care into the management of chronic diseases.
“A lot of studies focus on physical illness and not the psychological conditions that accompany these illnesses. This study confirms that diabetes has a significant psychological aspect and that patients need psychological interventions as part of their care,” he said.
Explaining the essence of Cognitive Behavioural Therapy, Dr. Karugahe noted that the approach helps people restructure their thoughts and behaviours.
“Imagine putting a sticker on your fridge that reminds you that some foods are not good for you and that healthier options are better. That is CBT. It helps people change the way they think and behave, and it can be used to address many behavioural challenges.”
The dissemination workshop was also attended by officials from the Ministry of Health, including Mrs. Christine Ninsiima Ahimbisibwe, Senior Programme Officer for Mental Health and Substance Abuse Control, and Mrs. Patience Butesi from the Department of Mental Health and Drug and Substance Abuse.
Mrs. Ahimbisibwe welcomed the findings and emphasised the need to integrate the study’s recommendations into Uganda’s clinical guidelines to enable healthcare workers to provide psychosocial support to patients living with chronic illnesses such as diabetes.
The human impact of the intervention was perhaps best illustrated by testimonies from participants who underwent the psychosocial training.
Tebugulwa Josephine, a retired teacher and employee at Mulago National Referral Hospital, said the intervention restored hope in her life.
“When we first joined the programme, we thought we were moving dead people. But now we have hope. I have hope of reaching 90 years. We were taught how to exercise and take care of ourselves. Even our families no longer treat us as sick people because we can now walk and participate in daily activities.”
Another participant, Bunje Joice, described the intervention as life-changing.
“People had already given up on me and were waiting for me to die. I could hardly walk, but now I can walk long distances and my diabetes levels have improved. Physical exercise has become my first medicine.”
Kyomuhendo Kate said the programme helped her manage stress and improve her health.
“I was so stressed and my legs were swelling, but after attending the treatment sessions, I am now much better.”
Sebuliba Bernard said the training transformed how he manages his condition.
“They taught us how to exercise, how to live and how to eat. If we follow what we were taught, we can change our lives.”
Based on the findings, the researchers recommended scaling up the intervention to district, regional and national referral hospitals, integrating psychosocial interventions into the training of health workers, and undertaking policy reforms to strengthen mental health support for people living with chronic illnesses.
The study was funded by the Makerere University Research and Innovations Fund (Mak-RIF) and brought together researchers from psychology and medicine, including co-investigators: Dr. Fredrick Nakwagala, Dr. Wilber Karugahe and Dr. Anne Ampaire.
