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.
Get news that’s free, independent and based on evidence.
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.
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.

Offsets don’t stop climate change.
Shortly before COP26, Amazon Watch and more than 170 organisations signed on to a statement under the headline “Offsets don’t stop climate change”.
The letter, from Doreen Stabinsky (College of the Atlantic, USA), Wim Carton (Lund University, Sweden), Kate Dooley (University of Melbourne, Australia), Jens Friis Lund (University of Copenhagen, Denmark), and Kathy McAfee (San Francisco State University, USA), states that, “Offsets don’t stop climate change because they don’t stop emissions.”
They write that,
In an ideal world, some types of offsets might theoretically balance out emissions with removals. But the whole point of an offset is that one entity gets to keep emitting.
And they explain that the problem is that with continued emissions, CO2 continues “to accumulate in the atmosphere where it resides for hundreds to thousands of years, and the temperature of the planet continues to increase”.
They point out that the oil industry is a primary beneficiary of offsetting and Carney’s taskforce was stacked with respresentatives of Big Polluters:
All the major oil companies are planning to continue with exploration and new extraction projects. None of them have plans for a managed decline of production that is anywhere near in line with the Paris goal aiming to limit warming to 1.5C. Indeed some fossil fuel majors have even stated their intent to increase exploration and production for at least the next five years. These are hardly decarbonisation goals. All of them intend to rely heavily on carbon offsetting to keep drilling and emitting-as-usual.
They conclude that if Carney were serious about addressing the climate crisis, he would “convene a taskforce on the managed decline of fossil fuels and bring the fossil fuel industry to the table”.
It’s not controversial to point out that offsetting does not reduce emissions (and therefore does not help address the climate crisis). Even proponents of offsetting will, if pushed, admit this fact:
In a press release about the statement signed by more than 170 organisations, Jim Walsh of Food & Water Watch says,
“Offsets are nothing short of a scam that corporate interests push, allowing them to continue polluting our climate and frontline communities with impunity. The harm does not end there, as these offset schemes displace indigenous communities and prop-up corporate agriculture and factory farming. Addressing the climate crisis means keeping fossil fuels in the ground, rather than pursuing these scams that harm our communities and climate for nothing other than corporate profits.”
Offsets don’t stop climate changeClimate-driven wildfires, flooding, droughts and other extreme weather events daily impact every corner of the globe.Yet the fossil fuel industry, big utilities, big agriculture, big finance — and their political allies — are pushing carbon offset schemes to allow them to continue releasing the greenhouse gases driving the climate crisis, harming Indigenous, Black, and other already-marginalized communities, and undermining sustainable farming and forestry practices.The science is clear: we need to rapidly phase out fossil fuels and emissions-intensive agricultural practices like factory farming, while protecting forests, wetlands, and other natural carbon sinks. Every delay means greater impacts on our climate and more pollution in historically overburdened communities.We call on leaders around the world to join us in rejecting offset schemes because these pay-to-pollute practices are nothing more than false and harmful solutions to the climate crisis.
- Nature-based offsets cannot “offset” fossil fuel combustion. While fossil fuel companies and other polluters would like fossil carbon and biological carbon to be fully interchangeable, this has no scientific basis. Fossil carbon emissions are effectively permanent, coming from reservoirs deep in the earth where they have been stored for millions of years. When burned, the carbon pollution remains in the atmosphere for hundreds to thousands of years. In contrast, crops, soils, oceans, and forests are “fast-exchange” carbon reservoirs that have limited carbon storage capacity and can re-release carbon back into the atmosphere over the course of a few decades, or sometimes even over a few days. Offsets confuse this basic science by wrongly treating the Earth’s biosphere as an endless source of potential storage for fossil carbon emissions.
- Offsets of any kind perpetuate environmental injustice. Greenhouse gas emitting industries are disproportionately sited in poor communities and communities of color, causing them to bear the brunt of pollution. Offset schemes increase pollution in these communities, worsening environmental injustice. Furthermore, by allowing pollution to continue in exchange for land grabs elsewhere, offsets often shift the burden of reducing emissions from the Global North to the Global South.
- The use of offsets is likely to increase greenhouse gas emissions. Polluters frequently purchase offsets for emissions-reducing practices by one entity, so that their own emissions can continue. In this case, emissions are still added to the atmosphere, so global warming continues. Polluters also purchase offsets for practices that could pull carbon out of the atmosphere, such as by planting forests or protecting existing forests. However, carbon storage in natural ecosystems is inherently temporary and highly reversible, as has been seen so clearly in the tragic forest fires in the U.S. west in the past few years. All that carbon can be released very quickly back into the atmosphere, again increasing emissions.
- Offsets can result in violations of the rights of Indigenous and tribal peoples. Satisfying market demands for offsets will require access to huge expanses of land and forest, lands already occupied by Indigenous Peoples, peasants, and local communities. As such, Indigenous lands are increasingly targeted by forest offset project developers, creating pressure and division in Indigenous communities.
- Offsets undermine sustainable farming and increase consolidation in agriculture. Carbon offset programs give additional leverage to already powerful corporations, including agribusinesses and factory farms, that have long squeezed farm income and drained rural economies, while increasing environmental pollution. Corporations and large landowners are best-positioned to develop offset projects, which further entrenches the factory farm and corn/soybean monocultural model at the expense of small farmers, including Black and Indigenous farmers and Tribal Nations. Instead of allowing the industrial, extractive model of agriculture to further prosper by selling offsets to industrial polluters, policy makers should support traditional and ecologically regenerative agricultural practices.
- Offsets markets create more conditions for fraud and gambling than for climate action. Existing offset schemes have already proven to be easily open to fraud. Yet the speculative trading of offsets derivatives and other financial products has already begun, prioritizing profit-seeking traders and speculators over economic and climate justice.
We call on global policy makers to reject offset schemes and embrace real climate solutions that will keep fossil fuels in the ground, support sustainable food systems, and end deforestation, while eliminating pollution in frontline communities.

NO more GE trees! Open Letter Denouncing Suzano Papel e Celulose’s glyphosate-resistant Genetically Engineered (GE) Eucalyptus
More than 50 organizations, networks and movements from Brazil and around the world denounce the release into the environment and the commercial use of a new transgenic eucalyptus from the Brazilian company Suzano Papel e Celulose!
The approval by the National Technical Commission on Biosafety (CTNBio) of the GE eucalyptus resistant to glyphosate, identified as 751K032, is a serious threat to life, to society and to nature. It was approved without any democratic consultation with Brazilian civil society in general and the neighboring communities of the areas where the plantations will be located in particular. The only concern was granting the license in the benefit of the commercial interests of Suzano Papel e Celulose, instead of the detrimental effect on life.
Organizations denounce the CTNBio decision from November 16, 2021 to approve the release into the environment, commercial use and any other related activities of the new GE eucalyptus developed by FuturaGene, owned by Suzano Papel e Celulose.
The letter ends by demanding the immediate revocation of the license granted for the use of Suzano GE eucalyptus 751KO32, as well as the action and intervention of the Federal Public Prosecution Service to revoke the decision made by the CTNBio, a decision made without a full public debate, especially in regions of Brazil that have been exposed for many years to eucalyptus monoculture.

UN seeks increased public finance to protect forests.
UN Secretary General, Antonio Guterres
Antonio Gutteres, the Secretary-General of the UN, made this call on Monday, May 2, 2022, at the opening of the 15th World Forestry Congress (WFC) in Seoul, South Korea.
The increase in the finance, he said, should include source-based payments and a dearth of environmental swaps to achieve a deforestation-free world.
Gutteres, who spoke through his Deputy, Amina Mohammed, also called for a budget and policy for forestry commitment among global communities.
He said it was unfortunate that about 4.7 billion hectares of forest were being lost annually to deforestation and environmental degradation in the last decade.
The UN chief called for concerted efforts toward achieving deforestation-free supply chains.
“Since the last congress in 2015, recognition of the critical role of forests of all types play in meeting the sustainable development goals and achieving the past agreements has gained much attention.
“The recent classical degradation on forest and land use has further underlined key transform to actions needed to save all forest and advance the 2030 agenda.
“This congress takes place right over the latest report of the intergovernmental panel on climate change.
“The panel warns that the world is dangerously close to irreversible topping point for forestry section, for the health of people, and for the planet,” he said.
According to him, this supports resilient livelihood, biodiversity consideration, sustainable economy and climate mitigation and adaptation.
“Forest remained under threat and in the last decade alone, the world has lost 4.7 billion hectares a year.
“We must specially recognise and act on the value of the forest hence the theme of the congress, ‘Building a Green, Healthy and Resilient Future with Forest.
“We need all stakeholders to come up with ideas and commitment that can be put into action,” he said.
Gutteres explained that forests could also be protected by expanding indigenous governance for forests in the perspectives of youth and women and using the latest scientific evidence and catchy head technology.
“I look forward to the outcome of this congress feeding into climate change and biodiversity negotiation and other policies.
“Together, I believe we can build a green, healthy and resilient future by realising the true value of the forest,” the UN scribe said.
In her remark, Princess Sasma Ali, Hashemite Kingdom of Jordan, canvassed a diversified approach to achieving success in building a green, healthy and resilient future with forest.
Ali is also Goodwill Ambassador of the Food and Agriculture Organisation (FAO).
Ali said that 30 per cent of the world’s forest had been cleared with another 20 per cent degraded.
She said it would require dedicated political will and the development of policy measures to reverse the tide.
The FAO ambassador also called for the mobilisation of funds in addition to engaging all stakeholders to achieve the target.
“Accordingly, there is no to engage all stakeholders more importantly indigenous people, and local communities’ members.
“They possess the knowledge, and the custody of this ecosystem coupled with scientific experts who can monitor the system,” she said.
Qu Dongyu, Director-General, FAO, acknowledged some progress in reforestation, particularly in Asia including countries like South Korea, Japan and India.
Dongyu said the congress was an opportunity to make further commitment toward achieving the 2030 deforestation-free world in accordance with the Sustainable Development Goals (SDGs).
