Welcome to Carbon Brief’s Cropped.
We handpick and explain the most important stories at the intersection of climate, land, food and nature over the past fortnight.
Key developments
Weather-related hunger
‘LARGE-SCALE HUNGER’: A new report from the Clingendael Institute, a Dutch thinktank, found that “around 2.5 million people in Sudan could die from hunger by September 2024”, Middle East Eye reported. The report said “that parts of the country have likely already reached the tipping point at which large-scale hunger transitions into large-scale death”, the outlet wrote. The civil war that broke out in Sudan in April 2023 has disrupted food supply chains and logistics, but the shortage “has been worsened by drought and flooding, likely exacerbated by climate change”, Truthout said. Al Jazeera reported that “more than 25 million people scattered across Sudan, South Sudan and Chad are ‘trapped in a spiral’ of food insecurity”, according to the World Food Programme.

PROLONGED DROUGHT: Zambia’s environment minister, Collins Nzovu, has warned that the drought that has gripped southern Africa in recent months is “a harbinger of what is in store for the region as the climate crisis worsens”, the Guardian reported. The newspaper continued: “People are reaching the end of their food stores, and importing from other countries in the region has become much harder as they too are feeling the impacts of the drought.” Hydropower capacity has also halved in the country, which receives about 95% of its electricity from dams. The Times of Zambia reported last month that the World Food Programme was giving Zambia $3.3m “to help the country respond to the drought”.
MARGINAL IMPROVEMENT: The Integrated Food Security Phase Classification (IPC), which monitors global hunger, “forecast that 28% of Afghanistan’s population, about 12.4 million people, will face acute food insecurity before October”, the Associated Press reported. This is a “slight improvement” over the previous IPC report, “but underline[s] the continuing need for assistance”, the newswire said. It added that “torrential rains and flash floods” in the northern part of the country last month killed more than 400 people, damaged or destroyed “thousands of homes” and turned farmland into mud. The Afghanistan Times reported that the floods have also “destroyed numerous water systems”, causing “difficulties in accessing sufficient clean water for drinking, cooking and bathing”.
END OF EL NIÑO: Meanwhile, despite the coming end to El Niño, “it is uncertain how soon a transition to a cooler La Niña will bring respite from the heat”, New Scientist wrote. The outlet explained: “El Niño is associated with hotter average temperatures and a distinctive pattern of weather conditions in much of the world.” It noted that background warming heightened the impacts of extreme weather events during this El Niño in many parts of the world, including flooding in Afghanistan and “intense” wildfire seasons in South America and Indonesia. But, it added: “Not all these effects were entirely negative. In the Horn of Africa, for instance, the rain helped ease a drought that has contributed to near-famine conditions in the region.”
Bird flu continues to spread
CASE BY CASE: The US reported a third human case of the H5N1 avian influenza and the first with the “respiratory symptoms that are more typical of human influenza infections”, CNN reported. All three cases so far have occurred in workers on dairy farms who had direct contact with infected cows. The outlet added that “the addition of respiratory symptoms doesn’t necessarily indicate that the virus has become more dangerous or that it may transmit more easily from person to person”. But in the New York Times, virologist Dr Rick Bright wrote that “the current bird flu situation is at a dangerous inflection point”.
SILENCE BEFORE THE STORM: Bright pointed out that the virus has now been found in 69 dairy herds in nine states. But the “agribusiness industry is eerily quiet about bird flu”, Gene Baur, an animal-rights activist, wrote in the Des Moines Register. He added that “lax responses from…industry indicate that there is no rush to spend the time and money needed to address this growing crisis”. Meanwhile, according to the Los Angeles Times, a “growing number” of states are moving to legalise the sale of raw milk, despite finding “high levels” of the virus in samples.
TWO FLUS: The first human case of H5N1 avian influenza in Australia was detected two weeks ago, in a child who had recently travelled to India, Reuters reported. The child has “made a full recovery” and there “was a very low chance of others becoming infected”, the newswire wrote. Meanwhile, a different strain of avian influenza has been detected near Melbourne, Reuters reported in a separate piece. The newswire wrote: “Hundreds of thousands of birds have already been destroyed after bird flu was found at two Australian egg farms last month.” According to the Victoria state government, “the outbreak poses no risk to consumers of eggs and poultry products”.
TREATY TALKS STALL: Meanwhile, the World Health Assembly ended without a finalised pandemic treaty, although member states agreed to extend the body’s mandate, with an aim to finalise the treaty by next year’s assembly, according to Down to Earth. The assembly did, however, “adop[t] crucial amendments to the International Health Regulations”. These included “pledging improved access to medical products and financing”, which will help protect the world against future pandemics, the outlet wrote. Al Jazeera explained that it appears that talks broke down over knowledge and technology sharing around new disease-causing pathogens. (For more on the importance of the pandemic agreement, see Carbon Brief’s DeBriefed from earlier this year.)
Offset push
MIXED MESSAGING: The US government announced new rules “to govern the use of voluntary carbon credits [while] seeking to boost confidence” in a market that has seen high-profile projects “failing to deliver” on emission cuts, Reuters reported. Meanwhile, a Financial Times story quoted US treasury secretary Janet Yellen calling for corporate buyers of carbon credits to “prioritise reducing their own emissions” and that participation in voluntary carbon markets should only “complement these efforts”. However, Yellen added that countries “need to use all the tools at our disposal”, including markets and private capital. The new federal guidelines attempt to define what “high-integrity” offsets are, the New York Times wrote, “meaning they can deliver real and quantifiable emissions reductions for projects that wouldn’t have happened otherwise”.
OFFSETS UNRAVELLING: Elsewhere, Bloomberg reported that one of the world’s biggest carbon-offsetting projects, based in Zimbabwe, is being withdrawn from Verra, a “key registry and standards body”. The Kariba forestry project, operated by Carbon Green Investments, “has emerged as one of the most controversial projects in the market for carbon offsets”, Bloomberg added. Kariba’s withdrawal from Verra “risks undermining one of the carbon market’s key insurance mechanisms”, which is a pool of surplus credits “set aside to cover events such as forest fires”, it said. Meanwhile, a SourceMaterial investigation with the Times questioned a claim from offset platform Carbon Done Right that it had “secured 57,000 hectares for offsetting” in Sierra Leone. The investigation found that no such leases had been registered with local authorities.
DWINDLING APPETITE: According to a new report by Ecosystems Marketplace, the market for carbon offsets “shrank dramatically” in 2023, falling from $1.9bn (£1.5bn) in 2022 to $723m (£551m) in 2023, the Guardian reported. The 61% contraction in market size was attributed to a “flurry of scientific studies and media reports that concluded millions of offsets were worthless”, the story adds. However, Prof Julia Jones of Bangor University, who co-authored one such study, told the Guardian – and wrote in Nature Ecology & Evolution – that she was “deeply concerned” that recent media coverage “gives the impression that the very idea of tackling climate change by slowing tropical deforestation is a scam”. She added: “This is not true and the idea could harm forests.”
News and views
‘BOILING NOT WARMING’: Thailand’s marine life is “suffering” due to record ocean temperatures, “worrying scientists and local communities”, the Bangkok Post reported. Mass coral bleaching is underway, with Lalita Putchim, a marine biologist with the country’s department of marine and coastal resources, telling the newspaper: “I couldn’t find a single healthy coral…Almost all of the species have bleached, there’s very little that’s not affected.” The temperatures – reaching close to 33C – are also impacting the livelihoods of local fishers, with potential knock-on effects for food prices and food security, the outlet noted.
POLAND FARMER STRIKES: A DeSmog investigation revealed that Orka – a new Polish farmers’ movement that stormed the country’s parliament on 9 May – rose to prominence “after it was championed by populist politicians”, despite identifying itself as an “apolitical” group of “common farmers”. DeSmog uncovered “a number of far-right links to two of the group’s leading figures”. Rightwing Polish MPs gave Orka “access to the parliament building” and have “also been quick to join” Orka’s protest, which has said it wants to put the EU Green Deal “in the trash”, the outlet added. Politicians named in the piece had not yet responded to DeSmog.
SEABED SUIT: WWF-Norway has sued the Norwegian government “for its controversial decision to open up vast parts of its continental shelf to deep seabed mining”, the Maritime Executive reported. The suit claims that the government’s impact assessment “fails to satisfy minimum requirements of the country’s subsea minerals act”. The outlet added that the NGO had sent an initial notice to the government in April, while the government responded that the lawsuit is “lacking merit”. According to the Guardian, the Norwegian Environment Agency “has also said the impact assessment does not provide a sufficient scientific or legal basis for deep-sea mining”.
WOLVES RETURN: The Irish Times reported that wolf populations are “making a comeback” in Europe “thanks to wildlife protection measures” introduced by the EU. According to the newspaper, the number of wolves has grown 81% since 2012, to more than 20,000, and their range is up 25%. While Spain, host to “one of the largest populations in the EU”, has “tightened” its measures to protect the wolf, a “backlash” is stirring at the EU level, it adds. In December, Ursula Von Der Leyen’s conservative party backed a proposal to downgrade the protected status of wolves, Agriland reported. And, last week, the EU council of agricultural ministers “heard calls for more to be done to address the rise in wolf attacks on livestock”.
NZ’S ‘WAR ON NATURE’: New Zealand’s rightwing government was accused of “waging a war on nature” by environmentalists after it made “sweeping cuts” to climate projects in its 2024-25 budget, the Guardian reported. While the country’s climate minister pointed to flood defences and a waste levy when asked about the absence of new funding for environmental protection, critics described these as “the ambulance at the bottom of the cliff without future-facing climate mitigation plans”, the paper added.
OJ INFLATION: Orange juice makers are considering switching to mandarins as wholesale prices have “gone bananas” following fears of poor harvests in Brazil, the Guardian reported. It added that orange trees in Brazil have been hit by an “incurable disease” after “extreme heat stress and drought during their key flowering period…fuelled by the climate crisis”. Florida, another key growing region, has been “hit by a series of hurricanes and the greening disease, which is spread by sap-sucking insects”, it added. The Financial Times quoted Kees Cools, the president of the International Fruit and Vegetable Juice Association, who said: “We’ve never seen anything like it, even during the big freezes and big hurricanes.”
MONKEY BUSINESS: More than 150 howler monkeys – “midsize primates known for their roaring vocal calls” – have died, apparently of heat stroke, amidst a major heatwave in Mexico, the Associated Press reported. In a northern Mexican animal park, “at least a hundred parrots, bats and other animals have died, apparently of dehydration”, the newswire added. Mexican newspaper La Prensa reported that volunteers were working to “establish drinking fountains for wildlife” in affected communities.

New science
Global groundwater warming due to climate change
Nature Geoscience
New research found that, on average, global groundwater is projected to warm by more than 2C over the 21st century under a medium-emissions pathway. By modelling the diffusion of heat from the surface through the ground and maps of water-table depth, researchers calculated monthly temperatures for groundwater around the world from 2000 to 2100. They found that groundwater temperatures increased by an average of 0.3C over 2000-20, although with significant variation from place to place. They concluded that climate change under a medium-emissions pathway could push groundwater resources for 77-188 million people above the “highest threshold for drinking water temperatures set by any country”.
African food system and biodiversity mainly affected by urbanisation via dietary shifts
Nature Sustainability
Increasing rice demand due to urbanisation will increase Africa’s methane emissions by 2.4% by 2050, according to new research. Using projections of urban expansion in Africa, researchers modelled land-use changes and the accompanying production changes for staple crops. They found that more than 3m hectares of land will be converted to urban land under a “middle-of-the-road” narrative – a relatively small proportional decrease, but with potential major impacts on local biodiversity. The authors argued that land-use planning and policymaking should take into account impacts on food production and biodiversity loss.
The human side of rewilding: Attitudes towards multi-species restoration at the public-private land nexus
Biological Conservation
A new study looking to understand US public opinion towards rewilding found more negative attitudes and behaviour when it came to reintroducing species that could harm livestock or humans or those that require more regulation. Conversely, interest groups favoured initiatives that involved conserving species migration as an ecological process. Researchers surveyed five stakeholder groups – “local ranchers, statewide ranchers, rural residents, urban residents and members of conservation organisations” – across the state of Montana. The results, they concluded, highlight “how achieving rewilding in working lands will require community engagement to increase public support and continued assessments of social processes that may limit multi-species restoration”.

Israel’s bombardment of Gaza during the conflict that broke out in October 2023 has wrecked progress towards adapting the enclave to climate change and left two million Gazans vulnerable to heatwaves, drought and disease, the Palestinian Authority (PA) said in a new climate plan submitted to the United Nations.
Palestine’s third nationally determined contribution (NDC), uploaded to the UN climate body’s website this week, says that while “the aggression on the Gaza Strip did not make the climate worse”, “it removed the housing, water and sanitation systems, health facilities, energy networks, roads and livelihoods through which people absorb a climate they were already struggling with.”
The 91-page document lists the types of infrastructure it says Israel has destroyed and notes how the destruction will worsen the impacts of climate change. It says the bombing of hospitals and rising hunger have make it harder for Gazans to cope with the health impacts of climate-driven heatwaves and waterborne diseases.
The destruction of water tanks, boreholes and desalination plants, meanwhile, have left Gazans struggling with the effects of water shortages and drought, while mass unemployment reduces people’s ability to afford climate-driven price rises. The erasure of most of the Strip’s homes makes it more difficult for people to avoid the sun’s increasing heat, the NDC said.
Many Gazans are now living in the ruins of collapsed buildings or in makeshift shelters and tents that offer little or no protection from high temperatures.
Palestine’s previous goals to cut emissions and adapt to climate change in Gaza, expressed in its last NDC five years ago, were based on a pre-war baseline that “no longer describes anything that exists”, the NDC says. Progress made since 2021 has now been destroyed, it adds.
Green reconstruction of Gaza
Instead of continuing to aim for these adaptation and emissions-reduction goals, the PA is now calling for the green reconstruction of Gaza. It says buildings should be constructed again in an energy-efficient manner with solar panels and served with modern water, waste and transport systems.
While the PA, controlled by the Fatah political party, continues to claim legitimate control of Gaza, the strip was effectively governed by Fatah’s rival Hamas between 2007 and the recent war. Control is now split between Israel and the political wing of Islamist militant group Hamas, after a US-backed ceasefire took effect in October 2025, although a UN-backed committee plans to take over.

More support needed to power Africa’s food systems with renewables, experts say
Renewable energy could help African food businesses boost productivity and competitiveness, but the upfront cost, fragmented markets and limited financing stand in the way
The United Nations, European Union and World Bank have jointly estimated that Gaza needs $71.4 billion of investment in the next two years to recover and build back. This process should be Palestinian-led, they said in April.
But US President Donald Trump has said the US should “take over” and “own” Gaza and redevelop it as the “Riviera of the Middle East”. Israel’s right-wing prime minister Benjamin Netanyahu has said that Israel should control the territory with civil administration managed by Palestinians favourable to Israel.
With occupation, targets conditional
In the other part of Palestine, the West Bank, the Palestinian Authority carries out some government functions, but ultimate control rests with Israel, which has occupied the West Bank since 1967.
Because Israel controls planning in most of the West Bank, the NDC argues that the PA cannot pursue all the climate projects it wants. In addition, Israel restricts the movement of PA officials, making data collection difficult, and controls the West Bank’s electricity supply meaning that the PA cannot control whether it comes from dirty or clean sources of energy.
Given this situation, the NDC says that all of Palestine’s new climate targets are conditional but it will aim to reduce emissions 12.8% below a business-as-usual baseline by 2035 and 17.1% by 2040. If the Israeli occupation ends and Palestine regains full sovereignty over its land and resources, it will aim for reductions of 15.1% and 19.1% by 2035 and 2040 respectively under an “independence pathway”.
That could allow, for example, for greater electrification and reducing emissions per unit of growth, the document said.
To achieve the 2035 emissions-reduction target and adapt to the impacts of climate change, the PA says it needs $8.6 billion in total. This funding would be spent on measures like encouraging solar farms and rooftop solar and scaling up solar water heating to cover four-fifths of households. To complement the planned increase in solar power, the authority wants to modernise the electricity grid and install battery storage.
In the transport sector, it aims to promote the uptake of electric vehicles, develop bus rapid transit corridors and scrap old polluting trucks and buses. In Gaza in particular, it wants to deploy 66 electric buses when the conflict ends.
To adapt to climate-driven drought, the NDC includes initiatives to reuse wastewater through treatment plants, build desalination plants in Gaza to remove salt from seawater, and promote irrigation for farmers.
The new climate plan was prepared by Palestine’s Environment Quality Authority, with support from the United Nations Development Programme and the governments of Britain and Spain.
The United Nations recognised Palestine’s statehood in 2012 and it joined the UN’s climate convention and signed the Paris climate agreement – which requires countries to submit more ambitious NDCs every five years – in 2016.
The Israeli foreign ministry did not respond to a request for comment. But in late 2024, then Israeli climate envoy Gideon Behar told Climate Home News that the war and the resulting environmental destruction in Gaza was the fault of Hamas.

Palestine: Israel’s bombing has left Gaza vulnerable to climate change
Solar power generation in the UK reached a new record over the summer of 2026, as temperatures across the nation soared, according to new analysis by Carbon Brief.
Collectively over June, July and August, solar farms and rooftops generated 8.8 terawatt-hours (TWh) of electricity in the UK*, as shown in the chart below.
Speaking to Carbon Brief, Chris Hewett, chief executive of trade association Solar Energy UK welcomed the new record, adding that it was driven by “clear skies and continued growth in deployment”.
This surge in generation took place amid the hottest summer on record in the UK, with five heatwaves between May and August.
Summer 2026 was the sixth sunniest on record, with more than 620 hours of sunshine, according to the Met Office. England and Wales – which experienced the most extreme heat – saw their second-sunniest summers on record.
June 2026 was the hottest June in England since records began in 1884, according to Met Office data, while Wales and the UK as a whole experienced their second-warmest June.
It was the driest July for England and Wales since records began in 1836, with some parts of London seeing no rain at all in the month, while Wisley in Surrey had no rain for 62 days.
In England, temperatures peaked at 38.1C at Kew Gardens in London on 13 August.
According to the Met Office, this summer’s record mean temperature was made 130 times more likely by climate change.
Amid these hot and sunny months, solar power generation increased 23% from the same period in 2025. This is double the level of solar generation over the summer of 2021, according to Carbon Brief analysis.
While solar panels can be affected by periods of extreme heat, the longer hours of daylight and higher levels of irradiation over the summer more than offset any efficiency losses.
June, July and August all saw solar set new monthly records for solar generation – July saw the highest solar generation in a calendar month ever, with 3.3TWh meeting 15% of overall electricity demand for the month.
As of the end of August, the total UK solar generation in 2026 stood at 17TWh – 13% higher than the same point in 2025.
The number of solar farms and rooftop installations has grown substantially in recent years, helping to boost generation. Domestic rooftop solar accounts for around 29% of total capacity.
In 2025, the UK’s solar capacity reached 21 gigawatts (GW) by the third quarter of the year, according to UK government figures. This is a jump of 3GW, or 18%, year-on-year, as Carbon Brief reported in January.
(Capacity is the maximum output possible from an electricity generation, whereas generation is what was produced over a certain time period, such as a day, month or year.)
According to the University of Sheffield, the installed solar capacity is now nearly 24GW.
This includes nearly 172,000 solar installations that have been fitted across the UK since the start of 2026, according to recent government figures. In July alone, more than 19,800 rooftop solar panels were installed – the equivalent of one installation every two minutes.
In total, nearly 1.7m households in the UK now have solar panels installed.
Over 26 heatwave days this summer – periods of at least three days when temperatures exceed the Met Office’s county-level heatwave temperature threshold – UK households with rooftop solar panels avoided an estimated £86.7m in electricity costs, according to analysis by Utility Bidder.
Talking about the surge in solar generation this summer, Hewett says:
“[It] not only kept bills down for people with solar and batteries in their homes, but helped keep overall power prices much lower than they would have been if Britain had been relying on more gas generation during the day”.
Despite the record generation, no new half-hourly solar power output record was set in the summer of 2026. This still stands at 15.2 megawatts (MW) on 23 April 2026.

Farmers around Europe are dealing with the aftermath of a summer of extreme heat, drought and wildfires that were exacerbated by climate change.
Human-caused climate change is increasing the severity and likelihood of many extreme weather events around the world, which is increasing volatility for food producers.
This summer resulted in, for example, shrunken potatoes in the Netherlands, reduced carrot harvests in France, dried-up rice fields in Italy and scorched olive groves in parts of the Mediterranean region.
Global food prices are currently at their highest level since early 2023 due to “heatwaves and energy price dynamics”, according to the UN Food and Agriculture Organization.
Other factors such as blocked fertiliser supplies in the Strait of Hormuz and high fuel costs have also played a role in this year’s agricultural outputs.
In the six charts below, Carbon Brief provides a snapshot of the impact this summer’s extremes are considered to have had on crop production and yields across Europe.
1. Most EU countries expect to see declines in cereal production this year
2. Most countries are recording reduced crop yields
3. Around €2bn worth of cereal losses after June heatwave
4. UK yields of wheat, barley and oats are all due to drop in 2026
5. Maize production in France is due to hit a four-decade low
1. Most EU countries expect to see declines in cereal production this year
France, in particular, will see heavy losses in the amount of cereals – such as wheat, barley and oats – it produces this year, according to European Commission data.
French cereal production is expected to drop by almost 8 megatonnes (Mt) in 2026, compared to 2025.
The chart above shows that most European countries, aside from Bulgaria, will also see production losses this year.
Germany is due to see the second-largest losses in production, dropping by almost 4Mt compared to 2025.
Prof Til Feike, a cropping systems expert at the Julius Kühn-Institut, says many areas in Germany and Austria, as with other parts of Europe, have been “hit hard by a long-lasting dry period in combination with record-high heatwaves”.
This has resulted in dry grassland for animals and lower yields of maize, which is a “key fodder crop” for livestock. He tells Carbon Brief:
“In the long run, farming must adapt better to more extreme weather conditions, not only heat and drought, but also prolonged wet periods. So, there is no one-fits-all solution for climate change adaptation.”
2. Most countries are recording reduced crop yields
Heat and a lack of water have “substantially worsened” crop expectations this summer in western and most of central Europe, according to a recent bulletin from the EU Joint Research Centre.
Yields are expected to be “significantly reduced”, with local crop failures “likely” in areas such as France, southern Germany, northern and central Italy, and Hungary, it added.
The chart below shows that yields of cereal grains – which, here, refers to the tonnes of a grain grown per hectare of land – are expected to fall in most EU countries in 2026.
Slovakia, Austria and Hungary are expected to see the largest declines in cereal yields, reducing by more than one tonne per hectare in 2026 compared to 2025.
The recent EU bulletin noted that irrigated crops performed well in Portugal this summer – the country with the largest yield increases. Other crops relying on rainfall showed growing signs of heat stress, it added.
3. Around €2bn worth of cereal losses after June heatwave
The record heatwave that hit many parts of Europe in June contributed to an estimated €2-2.3bn in cumulative grain production losses, as shown in the chart below.
The intense June heat in western Europe would have been “virtually impossible” just 50 years ago, according to a rapid climate attribution study. It was the region’s hottest June on record.
The Energy & Climate Intelligence Unit (ECIU) thinktank analysed June and July 2026 grain forecasts from Coceral, a European grain traders association.
ECIU estimated lost supply by multiplying the change in tonnes of grains between these two months by prices for harvest delivery in 28 European countries.
Major grain producers France, Germany, Hungary and Spain accounted for 86% of the lost revenue, according to the ECIU.
Extreme heat is also expected to have a wider economic impact across the continent. Analysis from Triodos Bank found that this summer’s extreme weather could reduce the EU’s gross domestic product (GDP) by around 1% this year, or around €180bn.
4. UK yields of wheat, barley and oats are all due to drop in 2026
If current trends continue, the average yields for cereals and oilseeds will result in the UK’s worst harvest since detailed records began in 1984, according to ECIU.
Barley yields could fall by 15%, oats by 14% and wheat yields by 6% year-on-year, according to 2026 harvest surveys from the Agriculture and Horticulture Development Board, a non-departmental public body that provides agricultural data to the UK government.
ECIU said that, even if the situation improves, this year is still expected to be one of the five worst harvests on record. This means that four of the five worst harvests in the UK have occurred in the past decade.
Consumers will likely see higher prices and/or smaller vegetables in supermarkets as a result, Tim O’Malley, chairman of UK company Nationwide Produce, told BBC News in August.
Other crops, such as berries, have grown successfully in the extreme heat. But the Guardian noted fears this could dip later this year “as plants become exhausted from heavy cropping during the heatwave”.
5. Maize production in France is due to hit a four-decade low
France has been acutely affected by this summer’s extreme weather, with more than 7,300 excess deaths during heatwaves and a record number of weather stations recording temperatures of above 40C.
The country is the EU’s largest agricultural producer, but heat, drought and wildfires have affected many crops.
The chart below shows that maize production is set to drop by more than one-third (35%) year-on-year.
This could result in France’s lowest maize production since 1980, according to data from Agreste, the country’s agriculture ministry’s statistics service.
Due to the heat, “record-early” grape harvests have also been recorded in various parts of the nation since mid-July, reported Le Monde. In some cases, this means “smaller, less juicy grapes, which will yield less wine”, explained the newspaper.
6. Declines in EU grains since 2025
Overall in the EU, data and projections indicate declines in the output of cereal grains this year.
Cereal production is set to fall by 9% compared to 2025, according to the European Commission.
Just one year in the past decade – 2024 – recorded lower production levels.
Maize production is set to be particularly affected, with projections indicating a 13% drop, to 52Mt – the lowest level in the EU since 2007.
