Insights for African countries from the latest climate change projections

Flooding is projected to increase in eastern Africa
The Intergovernmental Panel on Climate Change (IPCC) – a body of the UN tasked with providing scientific information on climate change – has released a major new report, pulling together evidence from a wide range of current and ancient climate observations. It’s the most up-to-date understanding of climate change, bringing together the latest advances in climate science.
It is crucial that we have a good understanding of the findings as they give an indication of what our future could look like.
According to the report global warming is evident, with each of the last four decades being successively warmer than any decade that preceded it since 1850. Average precipitation on land has also increased since the mid-20th century. In addition, there is high confidence that mean sea level increased by between 0.15 and 0.25m between 1901 and 2018.
The major concern is that as warming continues, more extreme climate events, such as droughts, are projected to increase in both frequency and intensity. This warming is mainly driven by greenhouse gas emissions from human activities such as burning fossil fuels (coal, natural gas, and oil) and coal production.

When it comes to African countries, the report projects an increase in average temperatures and hot extremes across the continent. The continent will likely experience drier conditions with an exception of the Sahara and eastern Africa.
Alarmingly, the rate of temperature increase across the continent exceeds the global average. In addition, as warming continues, the frequency and intensity of heavy rainfall events are projected to increase almost everywhere in Africa. Maritime heatwaves and sea level rises are also projected to increase along the continental shores.
Looking into the future, global warming could lead to an increase in hot extremes, including heatwaves. It could also lead to a decrease in cold extremes.
The projected dry and hot conditions will have a devastating impact on a continent where the economies of most countries, and the livelihoods of most people, are dependent on rain-fed agriculture. In fact, changes to the climate will affect almost all parts of our lives.
Regional impacts
In a scenario where global warming will reach at least 2°C by mid-21st century (as predicted by the report), southern Africa is highly likely to experience a reduction in mean precipitation (water vapour that falls, such as rain or drizzle or hail). This will adversely affect agriculture. Specifically, the region is likely to witness an increase in aridity, and droughts. We are already seeing this in Madagascar and South Africa.
This has serious implications for all sectors including agriculture, water and health. Drought would also likely reduce hydroelectric generation potential, adversely affecting energy dependent sectors. We are already seeing this at the Kariba dam which sits between Zimbabwe and Zambia.
In addition, there will be more tropical storms in the region. In southern Africa there’s been a southward shift in the occurrence of tropical cyclones. This is due to sea temperatures increasing as a result of global warming. The concern is that these events will be particularly destructive as seen in Madagascar and over Mozambique.

In relation to eastern Africa, the report projected an increase in mean precipitation that favours agriculture. However, increases in the frequency and intensity of heavy precipitation and flooding may cause a counter effect in some areas, such as arid and semi-arid lands.
There has been some conflicting information regarding rainfall in eastern Africa. This follows observations that the general circulation models, used in preparation of IPCC reports, do not simulate the observed rainfall well over the region. Most models project increase in rainfall while observations report the opposite. This has been termed ‘the paradox of east Africa climate’. This observed shortening of rainfall season that is not captured by the models explains the paradox.
Besides rainfall, the recorded and projected temperature which is expected to increase will decrease the snow and glaciers in the region. A rise in temperatures will result in a rise in malaria cases especially in highland areas within the region.
Northern Africa is a climate change hotspot. The report anticipates with high confidence increase in temperatures in the region,causing extreme heatwaves. Projected drying will increase aridity that already begun to emerge in the region and worsen water scarcity.

Further, the situation will increase the risk of forest fires, a threat to ecosystems. As is currently seen in Algeria where, so far this year, more than 100 fires have been reported across 17 provinces, killing over 40 people.
The report also anticipated that there will be a reduction in mean wind speed over northern Africa. The wind speed is dependent on temperature and consequently atmospheric pressure changes. This will limit the region’s wind power potential, however – on a positive note – it will equally reduce dust storms that cause health impacts, such as causing and aggravating asthma, and bronchitis.
Similarly, west and central Africa are projected to record a reduction in mean precipitation and experience more agricultural and ecological droughts. All these cast a dark cloud on agriculture and water in the region.

Along the African coastlines, the relative sea-level rise is likely to contribute to an increase in the frequency and severity of coastal flooding in low-lying areas, like the recent cases in Lagos, Nigeria. This causes massive destruction to delicate coastal ecosystems and will displace communities that live in coastal towns. The sea level rise equally causes saltwater intrusion, limiting availability of fresh water.

Which way for Africa?
Despite the projection of decrease in mean precipitation over nearly all the regions of Africa, heavy precipitation and pluvial flooding is likely. The increase in wet extremes has far reaching effects on nearly all socioeconomic sectors, from agriculture, water, environment to infrastructure. These are some of the key sectors in socioeconomic development.
This – compounded by growing populations – gives a worrying picture of the challenges that lie ahead. This is likely to widen the existing development gap, calling for concerted effort to strengthen response mechanisms to future challenges posed by climate change.

Global hunger falls, but millions in Africa still go without food, says UN
Published
2 days agoon
July 24, 2026
Geneva | Global hunger has declined for the third consecutive year, offering renewed hope that progress against food insecurity is possible. Yet for Uganda and the rest of Africa, the latest United Nations findings are a reminder that the continent continues to carry the heaviest burden of hunger despite improvements in many parts of the world.
The State of Food Security and Nutrition in the World 2026 (SOFI 2026) report, released jointly by five UN agencies, estimates that 645 million people experienced hunger in 2025, down from 659 million in 2024 and 688 million in 2022.
The figures indicate that global efforts to improve food security are beginning to bear fruit, but not fast enough to achieve the Sustainable Development Goal of ending hunger by 2030.
For Uganda, the report presents a mixed picture. While global hunger is declining, Africa has overtaken Asia as the region with the highest number of hungry people. Approximately 309 million Africans experienced hunger in 2025, compared to 292 million in Asia.
One in every five Africans remains undernourished, and more than half of the continent’s population continues to face moderate or severe food insecurity. These findings come at a time when Uganda is striving to transform agriculture from subsistence farming into a commercial, climate-resilient sector.
Agriculture remains the backbone of Uganda’s economy, employing the majority of the population and contributing significantly to export earnings. Yet erratic rainfall, prolonged droughts in some regions, flooding in others, crop pests, high post-harvest losses and fluctuating food prices continue to threaten food security for many households.
The UN report notes that while 2.1 billion people worldwide still experience moderate or severe food insecurity, Africa accounts for the highest share, with 56.6 per cent of its population unable to consistently access sufficient, safe and nutritious food. This means many families are forced to reduce meal sizes, skip meals altogether or settle for less nutritious diets. For Uganda, where rural communities depend heavily on rain-fed agriculture, climate change remains one of the biggest threats to food production.
Recent seasons have demonstrated how prolonged dry spells and unpredictable weather patterns can reduce harvests, increase food prices and place vulnerable households at greater risk of hunger.
The report also highlights another growing concern that resonates with Uganda’s public health priorities: malnutrition is no longer only about hunger. While millions still lack enough food, obesity and poor-quality diets are increasing across the world.
Globally, the prevalence of adult obesity rose from 12.1 per cent in 2012 to 16.2 per cent in 2024. At the same time, nearly 150 million children under five remain stunted due to chronic undernutrition, while only about one-third of children aged between six and 23 months consume sufficiently diverse diets.
Uganda has made progress in reducing child stunting over the past decade, but nutrition experts continue to warn that poor infant feeding practices, limited dietary diversity and food insecurity remain major contributors to child malnutrition. The challenge is compounded by rising food costs, making nutritious foods such as fruits, vegetables, dairy products and animal proteins increasingly difficult for many households to afford.
The report reveals that the average global cost of a healthy diet has risen sharply to 4.28 purchasing power parity dollars per person per day in 2025, compared to 2.94 dollars in 2017. Although fewer people globally are unable to afford healthy diets than four years ago, Africa is moving in the opposite direction.
More than two-thirds of Africans, 66.6 per cent of the population, could not afford a healthy diet in 2025. This is more than double the proportion recorded in Asia and Latin America.
For Uganda, where inflation in food prices periodically affects household purchasing power, the findings reinforce the importance of investing across the agricultural value chain rather than focusing solely on increasing production. According to the report, between 70 and 75 per cent of the price consumers pay for food is determined after it leaves the farm, through transport, storage, processing, wholesale and retail costs.
This suggests that investments in rural roads, irrigation, cold storage facilities, food processing, market infrastructure and efficient transport systems could significantly reduce food costs while increasing farmers’ incomes.
Reducing post-harvest losses, estimated to claim a substantial share of agricultural produce in Uganda each year, would also improve food availability without requiring additional land for cultivation. The report further warns that progress made globally could easily be reversed.
Ongoing conflict in the Middle East, rising energy and fertiliser prices, declining humanitarian funding and increasingly frequent climate shocks all threaten future food security. Even under optimistic projections, between 510 million and 520 million people could still be hungry by 2030, well above the level required to meet the global Zero Hunger target.
For Uganda, these global developments matter because the country remains connected to international food, fuel and fertiliser markets. Higher import costs translate into more expensive agricultural inputs and higher food prices, placing additional pressure on both farmers and consumers.
The UN agencies argue that reducing the cost of healthy diets will require targeted investments in agriculture, stronger food value chains, research and innovation, improved irrigation, climate-smart farming practices, better trade policies and social protection programmes that support vulnerable households.
Ultimately, the report offers both hope and caution. It demonstrates that hunger can be reduced through sustained investment and sound policies, but it also makes clear that progress is uneven and fragile.
Strengthening agricultural resilience, improving nutrition, expanding food processing and ensuring affordable access to healthy diets will be essential for countries in Sub-Saharan Africa in order to contribute meaningfully to the global ambition of ending hunger by 2030.
As the report concludes, a world where healthy food is affordable and accessible to everyone remains within reach, but only if governments, development partners, the private sector and communities work together to build food systems that are more resilient, inclusive and sustainable.

Wars are disrupting food systems, and ending world hunger requires urgent global action, experts say.

By the Witness Radio team.
Conflicts far from the world’s farms are reshaping how food is produced, traded, and accessed. Rising energy costs, fertilizer disruptions, and threatened trade routes expose the fragility of global food systems, increasing production costs and leaving millions vulnerable to hunger.
The global food crisis is deepening as multiple shocks put increasing pressure on food systems worldwide. According to the World Food Program (WFP), hundreds of millions of people face crisis-level hunger, with conflict, climate change, economic instability, and displacement driving food insecurity. Countries already struggling with poverty and fragile economies remain the hardest hit.
More than 295 million people across 53 countries and territories faced acute hunger in 2024, according to the Global Report on Food Crises. This was an increase of nearly 14 million compared with 2023, driven mainly by conflict, economic shocks, climate extremes, and displacement.
The war in Ukraine showed how conflict in one region can disrupt food supplies worldwide. Ukraine is one of the world’s leading exporters of wheat, maize, and sunflower oil, while Russia remains a major supplier of fertilizers and agricultural inputs. Disruption of Black Sea trade routes and uncertainty over exports triggered sharp increases in food and fertilizer prices, affecting farmers and consumers thousands of kilometers away.
Although global grain markets have gradually stabilized since the initial shock, experts say the structural vulnerabilities exposed by war remain unresolved. Many countries still rely heavily on a handful of exporters for staple foods and farm inputs, leaving them exposed whenever geopolitical tensions escalate.
Similar concerns are emerging from the Middle East. Disruptions surrounding the Strait of Hormuz, one of the world’s busiest shipping corridors, have raised fears over global supplies of oil, natural gas, and fertilizers. Because modern agriculture depends heavily on fuel and fertilizer, a prolonged interruption in these supplies has immediate consequences for food production.
During a ministerial meeting of the MED 9++ countries on “Supporting Food Security and Access to Fertilizers”, United Nations Director-General of the Food and Agriculture Organization (FAO) Q.U. Dongyu warned that the current crisis extends far beyond geopolitics, affecting food production, trade, agricultural inputs, and access to food worldwide.
“This is not only a geopolitical crisis, but also a disruption at the core of the global agrifood system,” he said.
He explained that agriculture follows fixed seasonal calendars and that fertilizers must be applied at precise stages of crop development.
“Agriculture operates on a crop calendar that cannot be postponed. Fertilizers must be applied at specific moments in the crop cycle. If they do not arrive on time, yields are reduced, regardless of what happens later.” He added.
According to QU Dongyu, even delays of a few weeks could reduce harvests, tighten food supplies through 2026 and 2027, and raise food prices worldwide, particularly in import-dependent countries across Africa and Asia.
Agricultural economist Dr. Joseph Glauber, a senior research fellow at the International Food Policy Research Institute (IFPRI) and former Chief Economist at the United States Department of Agriculture (USDA), says today’s food crisis is increasingly driven by rising production costs rather than shortages alone.
In an interview with Witness Radio, Dr. Glauber said energy prices are now one of the biggest factors pushing up food costs.
“The biggest link has been through energy. Higher energy prices mean higher shipping, transport, and processing costs. Consumers don’t eat wheat; they eat bread and processed foods that require energy throughout the production chain,” he added.
Dr. Glauber noted that while global prices for crops such as wheat and maize have risen only modestly, fertilizer and energy costs have risen much faster, leaving many farmers with shrinking profit margins.
“For farmers, profits have declined because input costs have risen faster than the prices they receive for their produce,” he said.
According to Dr. Glauber, African countries face unique challenges because they depend heavily on imported fertilizers and face higher transport costs than larger importing economies.
“Africa is quite vulnerable because shipment sizes tend to be smaller and transport costs are relatively higher,” he explained.
He noted that although fertilizer use varies significantly between African countries, higher prices are already putting enormous pressure on farmers across the continent.
Beyond these immediate impacts of war, experts say the world faces a broader systemic crisis. The Club of Rome has also warned that shocks from the COVID-19 pandemic and the war in Ukraine, to disruptions around the Strait of Hormuz and increasing geopolitical instability, have exposed profound weaknesses in global food systems.
The organization says food security can no longer be viewed apart from peace, climate resilience, and energy security. Governments should instead pursue integrated approaches that strengthen local food production and reduce dependence on vulnerable international supply chains.
Experts are calling for an end to armed conflicts that threaten food production, investment in regenerative agriculture, stronger land rights for smallholder farmers, diversification of food crops beyond the world’s heavy dependence on wheat, maize, rice, and soybeans, expanded regional trade, and a faster transition away from fossil fuel-dependent agriculture.
Hunter Lovins, President of Natural Capitalism Solutions and a member of the Club of Rome, says the world already knows many needed solutions.
“This is not a warning about some distant future. It is a warning about next year’s harvest. We know what works. What we lack is not solutions, but the political will to invest in them before the crisis, rather than after,” she said.

Campaigning LC I Chairpersons Barred from Land Transactions Until Polls End.
Published
1 week agoon
July 17, 2026
The Ministry of Lands, Housing and Urban Development has temporarily barred Local Council I (LC I) chairpersons seeking re-election from participating in land-related transactions, citing concerns over possible fraud and disputes during the election period.
In a public notice issued on Thursday, the ministry directed all campaigning LC I chairpersons to stop witnessing, endorsing, recommending or overseeing land transactions until the electoral process is concluded.
The directive comes as campaigns for village chairperson elections enter the final days ahead of polling on July 28.
“The advisory has been issued as a precautionary measure to safeguard the integrity of land transactions during this transition period and to minimise the risk of disputes, fraud, or other irregularities that may arise,” the ministry said in the notice.
The ministry advised members of the public against relying on LC I chairpersons who are actively campaigning for services involving the witnessing of land sale agreements, verification of ownership, handling of boundary disputes or any other transaction requiring local administrative involvement.
Individuals with urgent land matters were encouraged to seek assistance from qualified legal practitioners or use other lawful channels until the elections are completed.
“The Ministry urges the public to exercise patience until the election process is concluded. This precaution will help prevent costly mistakes and safeguard the interests of all parties,” the notice added.
The temporary restriction comes amid continued concerns over land disputes, which remain among the leading sources of conflict in Uganda, with local leaders often playing a key role in verifying ownership and facilitating village-level transactions.
Although LC I chairpersons do not have the legal mandate to transfer land ownership or issue titles, they are commonly relied upon during land transactions because of their knowledge of residents and local land histories.
They often help confirm the identity of sellers, identify boundaries and witness sale agreements alongside members of their executive committees, providing community-level verification before transactions are completed.
Legal experts have previously cautioned that LC I endorsements only provide local credibility and do not replace formal requirements under Uganda’s land laws. Buyers are still required to conduct proper due diligence before purchasing land.
According to the Electoral Commission roadmap, elections for Village (LC I) chairpersons will be held on July 28 across Uganda’s 71,214 villages. Elections for Parish (LC II) chairpersons will follow on August 10.
The Ministry of Lands said LC I chairpersons will resume their normal involvement in land-related matters after the conclusion of the electoral process.
