The Serengeti-Mara ecosystem, spanning 30,000 square kilometers across Kenya’s Maasai Mara and Tanzania’s Serengeti, is a vital habitat with diverse landscapes, including savannahs, grasslands, riverine forests, and acacia woodlands. This ecosystem hosts the Great Migration, where millions of wildebeest, zebras, and other herbivores journey annually in search of food and water. This migration sustains numerous predators like lions and cheetahs, maintaining an ecological balance that exemplifies the region’s biodiversity. The ecosystem also supports species like elephants, giraffes, hippos, and a rich variety of bird species, creating a unique setting for intricate ecological interactions.

However, climate change threatens the stability of this ecosystem. A study featured in The Guardian, conducted by a research team from universities in Europe, IUCN, and Kenya Meteorological Department has examined the Mara-Serengeti’s weather patterns since 1913, noting increased temperatures, variable rainfall, and recurring severe droughts over recent decades. Average minimum temperatures have risen significantly, with Narok Town showing a 5.3°C increase from 1960 to 2024. Rainfall has also increased, alongside more frequent and intense droughts and floods, all of which are straining resources vital for wildlife and communities alike.

Global climate systems, especially the Southern Oscillation Index (which influences El Niño and La Niña events) and the Indian Ocean Dipole (IOD), have exacerbated these extreme weather conditions. Since 1970, El Niño and La Niña events have become more intense and frequent, leading to unpredictable rainfall and drought cycles in East Africa. Additionally, a warming Indian Ocean has strengthened the IOD, contributing to more frequent severe floods and droughts. These intensified climate patterns, driven by global warming, disrupt traditional migration and breeding cycles, reduce water and vegetation availability, and heighten competition between wildlife and human communities.

The impact on the ecosystem is profound. Wildlife populations are declining as animals face shrinking habitats and limited resources. Field observations, historical data from Kenya’s Game Department, and district records show that extreme weather events have repeatedly coincided with notable shifts in wildlife distribution and population. The researchers systematically ruled out other factors like poaching, pollution, or disease, confirming that climate change is the main driver.

The Serengeti-Mara ecosystem stands at a critical juncture. Conservation efforts must adapt to mitigate the effects of climate change and ensure the long-term resilience of this biodiverse landscape. Balancing the needs of both wildlife and local communities is essential to preserving the ecosystem's health and supporting those who depend on it.

According to the World Health Organization (WHO), 4.5 billion people worldwide lack access to essential healthcare services. Amidst global health challenges, more than 100,000 mpox cases and 200 deaths have been confirmed, and outbreaks of cholera and other diseases are escalating. A report predicts climate change could cause 14.5 million additional deaths by 2050 and impose a $1.1 trillion burden on healthcare systems. Experts warn that global preparedness remains inadequate, with lessons from the COVID-19 pandemic largely unlearned. Read more from this report by Al Jazeera.

A new study highlights the critical role of addressing gender inequalities in improving both human and environmental health. Authored by Claudia Cataldo, Roberta Masella, and Luca Busani, the research explores how the gender gap—particularly in education and political empowerment—correlates with life expectancy and environmental performance across 155 countries.

The study emphasizes that reducing gender disparities, especially in educational attainment, can positively impact not only societal well-being but also ecosystem vitality and public health. By closing the gender gap, nations could significantly enhance the effectiveness of the One Health approach, which integrates human, animal, and environmental health.

A recent paper highlights the importance of integrating gender perspectives into the One Health approach to better manage the risks at the human-animal-environment interface. Researchers Claudia Cataldo, Maria Bellenghi, Roberta Masella, and Luca Busani emphasize that gender-specific roles influence individuals' exposure to zoonoses and other infectious diseases.

The paper presents case studies on avian influenza and leptospirosis, showing how women, especially in rural communities, face higher risks due to their domestic and caregiving roles. By incorporating gender analysis, the One Health approach can improve public health interventions and reduce infection risks.

The IGAD Climate Prediction and Applications Centre (ICPAC) has released its October to December 2024 seasonal forecast, revealing contrasting weather patterns across East Africa. Drier-than-normal conditions are expected in the eastern parts of the region, particularly in southern Ethiopia, Somalia, eastern Kenya, and central and southern Tanzania. These areas face increased risks of drought, which could exacerbate food insecurity and affect livelihoods. On the other hand, western parts, including northern Uganda, western Kenya, northern Tanzania, southern Burundi, and parts of Rwanda, are predicted to receive above-normal rainfall, likely boosting agricultural productivity and water availability.

This forecast highlights the urgent need for coordinated action to mitigate the impacts of these climate extremes. Warmer-than-average temperatures are also expected across the region, with the highest probabilities in eastern Tanzania, Kenya, and Ethiopia. In contrast, cooler conditions are anticipated in northern Tanzania and parts of Uganda, Kenya, and South Sudan. Experts, including IGAD's Executive Secretary Dr. Workneh Gebeyehu, stress the importance of early warning systems and preparedness efforts to address the region's food security challenges and build resilience against the growing threat of climate change.

Burundi’s Ministry of Health declared a cholera outbreak on Wednesday, 6th September 2023, with 15 cases reported in the western part of the country, an area prone to water shortages.

Polycarpe Ndayizeye, spokesperson for the Ministry of Public Health and AIDS Control, confirmed that cholera patients had been admitted to hospitals and treatment centers in the municipality of Bujumbura. He called on authorities, residents of affected areas such as Bujumbura, Gatumba, and Rugombo, and all stakeholders to collaborate in combating the outbreak. Residents, especially those in impacted districts, were urged to strictly adhere to hygiene practices to help contain the disease.

Earlier this year, cholera claimed two lives in Bujumbura’s health district, notably at Kajaga beach on Lake Tanganyika. Water shortages, particularly during the dry season from May to September, exacerbate the risk of cholera outbreaks in Burundi’s western region.

Causative agent

Cholera is caused by the bacterium Vibrio cholerae. It produces a toxin that targets the intestines, leading to severe watery diarrhea and dehydration. According to the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), not all strains of V. cholerae cause illness; only specific toxin-producing strains are responsible for cholera outbreaks.

How cholera spreads

Cholera spreads through the consumption of contaminated food or water, particularly in areas with inadequate sanitation or limited access to clean water. The bacterium thrives in environments where drinking water, food, or sanitation is compromised, often after natural disasters or in densely populated areas.

Symptoms

Symptoms of cholera typically manifest within 2-5 days after exposure and include:

Profuse watery diarrhea (often described as “rice-water stools”)

Vomiting

Rapid dehydration

Muscle cramps

Severe thirst

If untreated, cholera can lead to shock and even death within hours due to the rapid loss of fluids.

Preventive measures

Preventing cholera requires addressing the core issues of water and sanitation. The WHO, Africa CDC, and US CDC recommend the following preventive actions:

Ensuring access to safe drinking water by boiling, treating with chlorine, or using bottled water

Proper disposal of human waste

Regular handwashing with soap, especially before eating and after using the bathroom

Safe food handling, including thoroughly cooking food and washing fruits and vegetables

Vaccination in high-risk areas, although vaccines alone are not a substitute for proper hygiene and sanitation practices

What to do if you get cholera

Immediate rehydration is crucial in treating cholera. The WHO recommends:

Drinking Oral Rehydration Salts (ORS) solution to replace lost fluids and electrolytes

Seeking medical care immediately if severe symptoms like frequent vomiting or extreme diarrhea occur

In severe cases, intravenous (IV) fluids may be necessary if oral hydration is insufficient

Treatment

Cholera treatment primarily focuses on rehydration. Antibiotics can also be prescribed in more severe cases to shorten the duration of the illness and reduce the volume of diarrhea. Zinc supplements are also recommended for children to aid recovery. Access to adequate treatment dramatically reduces cholera’s mortality rate to less than 1%, according to the WHO.

Regional impact

Burundi is not alone in facing cholera outbreaks. A recent update from the WHO African Region, as of August, 2023 reported cholera cases across 15 countries. Among the latest outbreaks, six countries—Burundi, Cameroon, Kenya, Mozambique, Uganda, and Zimbabwe—account for over 200 new cases. While the overall trend in the region is declining, WHO and other public health authorities urge countries to bolster surveillance, readiness, and community-based prevention measures, especially around border crossings to limit cross-border infections.

Between March and May 2024, Eastern Africa experienced devastating heavy rains and widespread flooding, driven by El Niño. Known as the Long Rains, this period caused landslides, mudslides, and severe damage across the region. The effects were particularly harsh on women and children, who lost lives, homes, and farmland. Agriculture, an industry where women play a crucial role, was severely impacted.

Women, often the primary caregivers, were especially affected. Their responsibilities for securing water, food, and healthcare for families became more difficult with the destruction of homes and displacement. Many women were forced into temporary shelters, where they faced increased risks of gender-based violence, including harassment and abuse.

The floods also triggered major public health crises, with clean water and sanitation systems compromised. Diseases such as malaria, cholera, and measles surged, posing serious health risks to pregnant women and children. Access to healthcare services became increasingly limited, further worsening maternal health issues.

To address health concerns during floods, the World Health Organization (WHO) recommends several protective measures. Communities need to be aware of evacuation routes and warning signals, with women, children, and people with disabilities given priority. Ensuring the availability of clean drinking water is critical, particularly for women responsible for water collection and food preparation. Good hygienic practices and safe food preparation techniques are essential to reduce the risk of disease outbreaks, while avoiding flooded areas and using mosquito repellents help minimize exposure to hazards like drowning or mosquito-borne diseases, including malaria.

Looking ahead, proactive measures are vital to reduce the impact of future disasters, which are becoming more frequent due to climate change. Monitoring weather forecasts can help communities prepare, particularly women, who often lack access to timely information. Safe shelters and preparedness kits with essential supplies, such as flashlights, cash, and first aid, can empower women to protect their families. Investments in infrastructure, agriculture, clean water, healthcare, and emergency systems are necessary to build resilience. Designing buildings to withstand extreme weather and relocating from flood-prone areas can offer additional protection, especially for women who manage household resources.

By prioritizing gender-sensitive responses and addressing the specific needs of women and vulnerable groups, Eastern Africa can better prepare for future natural disasters, fostering more resilient and inclusive communities. More details on this Link 

South Sudan’s government has ordered all of the nation’s schools to close indefinitely beginning Monday, March 18, because of a heat wave that could see temperatures rise to as high as 45C (113F) sweeping across eastern Africa. The government has also instructed parents not to allow children to play outdoors and asked them to report any signs of heat exhaustion or heatstroke. 

In a joint statement by the Health and Education ministries, the authorities warned that any school found open would have its registration withdrawn. “The Ministry of Health and the Ministry of Environment and Forestry will continue to monitor the situation and inform the public accordingly,” the statement read. 

According to the Environment ministry, the capital Juba and most parts of South Sudan are experiencing a heat wave with temperatures forecast to rise to as high as 45 degrees Celsius. This week temperatures could rise to 41 degrees Celsius. The extreme hot weather is expected to last at least two weeks. Earlier the Health ministry had issued an advisory stating that “extended periods of high day and night-time temperatures create cumulative physiological stress on the human body”. 

This, the ministry said, exacerbates the top causes of death globally, including respiratory and cardiovascular diseases, diabetes mellitus and renal disease. “There are already cases of deaths related to excessive heat being reported,” authorities said in a statement on Saturday. The Health ministry advised people to reduce the heat load inside the apartment or house, close windows and shutters especially those facing the sun during the day and turn off artificial lighting and as many electrical devices as possible. 

The residents are also required to hang shades, draperies, awnings or louvers on windows that receive morning or afternoon sun, and hang wet towels to cool down the room air. “Electric fans may provide relief, but when the temperature is above 35 degrees centigrade, may not prevent heat-related illness. It is important to drink fluids,” the advisory says.

 Those living in air-conditioned houses were advised to close the doors and windows and conserve electricity not needed to keep them cool, to ensure that power remains available and reduce the chance of a community-wide outage. For beddings, the ministry urged use of light bed linen and sheets, and no cushions to avoid heat accumulation. People were advised to drink water regularly and avoid alcohol and too much caffeine and sugar, which are dehydrating. They were also urged to eat small but frequent meals and to avoid foods that are high in protein. 

The ministry urged people to be their brothers’ keepers, checking in especially on family, friends, and neighbours who spend much of their time alone. Vulnerable people might need assistance on hot days, it said. “If anyone you know is at risk, help him or her to get advice and support. Elderly or sick people living alone should be visited at least daily. If a person is taking medication, ask the treating doctor how it can influence thermoregulation and the fluid balance,” the Health ministry advised.

The onset of heavy rains throughout the EAC region and reports of flooding, and post flood effects have not spared the Nimule/Elegu border between South Sudan and Uganda. On 5th November 2023, unprecedented volume of water spread throughout the border areas, submerging the markets, parking areas and residential areas.

At Nimule/Elegu border, the main economic activities around the area is trade, ranging from transportation, food vending, bars, lodging, cross border trade in agricultural produce, animals, animal products and others. On a daily basis, cross border communities move on either side to access basic services like healthcare, education, social events and retail trade including accessing eating places.

The following key challenges are foreseen:

• Contamination of water sources and associated problems.
• Increase in malaria cases
• Loss of business
• Contamination and possible food poisoning
• Increased cost of living for the Border Officials and the community.
