Large-scale banana plantations in Latin America and the Caribbean could face a “dramatic” reduction in “suitable” growing area by 2080 due to rising temperatures, a new study warns.
Banana production is a labour-intensive process and the $25bn banana industry provides employment for more than one million workers globally. Latin America and the Caribbean are responsible for 80% of the world’s banana exports.
The study, published in Nature Food, investigates how climate change could impact export-driven banana plantations in the world’s biggest banana-exporting region.
It finds rising temperatures will drive a 60% reduction in the land area currently suitable for large-scale banana plantations in the region by 2080.
As the suitable area for banana plantations shrinks, farmers will need to adapt through implementing irrigation, implementing drought-resilient varieties of banana and shifting their growing regions, the study says.
An expert not involved in the study warns that “the current intensive banana industrial model perpetuates certain injustices towards farmers”. She tells Carbon Brief that the research “provides valuable insight about the constraints [and] risks”, adding that it “should be a call for adaptation – and also transforming the industry for the better”.
The banana industry
Bananas are one of the most commonly exported and consumed fruits in the world and a key source of nutrition for more than four million people.
The banana sector is a growing industry, currently worth around $25bn globally. The map below shows the mass of bananas produced in 2022, in tonnes, per country.
While Asia is the world’s largest banana producer, Latin America and the Caribbean are responsible for around 80% of the world’s banana exports – particularly from Ecuador and Costa Rica.
More than 1,000 different varieties of bananas are grown around the world, with the sweet yellow Cavendish banana making up around half of global banana production. This cultivar is typically grown in large-scale monoculture plantations in Latin America, using extensive irrigation and drainage facilities. Large export plantations can be up to 5,000 hectares in size (50 square kilometres).
Mapping plantations
To assess the distribution of banana plantations throughout Latin America and the Caribbean, the authors developed a high-resolution map of banana production for the year 2019. They used data from NASA’s Sentinel-1 SAR and an algorithm to identify banana plantations in the satellite images.
The authors only include banana plantations larger than 0.5 hectares in area in their map, because the study focuses on bananas grown at a large scale for export. They also do not include banana production by smallholder farmers, as their crops are often in sparser, mixed-cropping systems that are harder to identify in images.
The authors identified and validated more than 360,000 plantations in total.
They authors combined their banana plantation distribution map with a wide range of climatic and socioeconomic data, including temperature, rainfall, elevation, soil acidity, latitude, irrigation infrastructure, human population density and distance to the nearest port.
To identify the conditions best suited for banana plantations, the authors identified ranges for each of these variables where 90% of mapped banana plantations were observed.
The results show that banana plantations are typically found at lower elevations and in more acidic soils than other croplands in the region. They are also found in areas with higher population density and close to ports. Three-quarters of the mapped banana plantations in this study are within 86km of the nearest port, the study finds.
Dr Varun Varma, the lead author of the study, is an ecosystems services modeller at Rothamsted Research in the UK. He tells Carbon Brief that large-scale banana farming “relies heavily on access to labour”. He adds:
“In these intensive export-focussed farms, bananas – a perishable product – are continuously harvested, processed, packaged and made ready for transport by sea in large shipping containers. Being closer to a port would be a logistical advantage.”
The authors also find that irrigation plays an important role in determining where bananas can grow.
Prof Matti Kummu from Aalto University’s water and development research group, who was not involved in the study, praises the authors for considering so many variables. He tells Carbon Brief that this is an “important and impressive study”, adding that its approach could be used for other similar crops.
Rising temperatures
Next, the authors modelled temperature and rainfall over Latin America and the Caribbean, using 12 climate models from the sixth coupled model intercomparison project (CMIP6) under the “middle-of-the-road” SSP2-4.5 warming scenario.
By combining simulations of temperature and rainfall across Latin America and the Caribbean with data on elevation and soil acidity, the authors find that around 3,340,000 square kilometres (km2) of land is currently “suitable” for banana plantations.
Central America, coastal Brazil and the northern and southern borders of the Amazon basin are the most suitable, they say.
Factoring in socioeconomic conditions, such as population density and distance to a port, shrinks the “suitable area” to 990,000km2. This “brings into focus how important socioeconomic factors are, and will be, in adapting to climate change”, Varma says.
The authors also investigated how climate change may impact the “suitable” area for banana plantations over the 21st century. The maps below show how changes in temperature (left) and rainfall (right) are expected to impact the suitability of land for banana plantations under the projected climate in 2061-80.
The colours indicate regions suitable for producing bananas for export in both the recent past (1970 to 2000) and future (blue), those suitable in the recent past, but not in future (red) and those that were not suitable in the recent past, but will be in the future (green).
The authors find that under the SSP2-4.5 scenario, “increasing temperature is the sole climatic driver of suitable area loss”. In contrast, changes in annual rainfall will not noticeably change the distribution of land suitable for banana plantations – partly due to the presence of irrigation, the authors say.
Overall, they find that changes in climate will shrink the area of land suitable for banana plantations by 60%, if no changes are made to irrigation infrastructure or other socioeconomic factors.
Dr Monica Ortiz is an environmental scientist and assistant professor at the University of Concepción in Chile, who was not involved in the study. She tells Carbon Brief:
“60% is no small figure and this means that banana-growers need to do climate-resilient planning to maintain their livelihood and business model.”
The paper finds that implementing more irrigation infrastructure where needed could expand the future suitable area. Adding this adaptation measure would mean that future climate change would only shrink the current area of land suitable for growing bananas by 41%.
The authors find that due to warming, the suitable area for banana production will decline by 2080 in most exporting regions in Latin America and the Caribbean. The study says that Colombia and Venezuela will become “almost entirely suboptimal for export production”.
The authors then used a series of equations developed in paper they published in 2019 to calculate banana yields from data on temperature and rainfall.
Yield in current banana producing areas will decline for most countries, the study says. It finds that “Ecuador and Brazil are the only major producers expected to see yield increases in current banana production areas due to climate change”.
Adaptation
As the area suitable for banana production shrinks, farmers will need to adapt to the changing conditions. These measures include maintaining irrigation supplies and breeding “drought-tolerant banana varieties”, the authors say.
However, they note that farmers in the global south “may be less able to adapt agricultural practices to cope with changing climate than their counterparts in wealthier countries”.
Prof Kenneth Feeley from the University of Miami was not involved in the study, but has conducted separate research on the impacts of climate change on banana growing regions.
He tells Carbon Brief that as a result of widespread irrigation, many growers have turned large areas of “pristine desert habitat” with low rainfall into banana plantations. This is a “major transformation of the ecosystem”, which may not be “good for the environment”, he warns.
Feeley adds that Cavendish bananas are also facing “attacks” from the fungus Fusarium, which are becoming a “major problem for banana production”. The fungus is spread through raindrops bouncing between plants, but the use of drip irrigation can “limit” the spread of the fungus, he explains.
Additionally, lead author Varma notes that rising temperatures are creating “increasingly inhospitable working conditions in this labour-intensive sector”.
Ortiz tells Carbon Brief that “the current intensive banana industrial model perpetuates certain injustices towards farmers”. She explains that farmers “work hard and are paid little”, adding that women are typically assigned the tasks that are paid the least.
She adds:
“The time is indeed ripe for change. I think the study provides valuable insight about the constraints, risks and should be a call for adaptation – and also transforming the industry for the better.”

DeBriefed 19 June 2026: Bonn talks end in ‘gridlock’ | Energy’s ‘new era’ | Oceans in climate negotiations
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Bonn talks close
‘SIDE-STEPPING AND STALLING’: UN climate talks in Bonn have ended in “gridlock”, according to Climate Home News. The outlet reported on the failure to balance developing countries’ need for climate-adaptation finance with “richer nations’ desire to move forward” on emissions cuts. It added that both topics were subject to “rule 16”, meaning no agreement could be reached and work will be pushed to the COP31 summit in Turkey. Inside Climate News quoted UN climate executive secretary Simon Stiell, who said the talks had seen “side-stepping and stalling”.
JUST TRANSITION: One “glimmer of hope” came from negotiations on achieving a “just transition”, reported Euronews. The news outlet said negotiators “made headway on operationalising the Belém-Antalya mechanism”, intended to support people in the shift to a low-carbon economy. However, Politico concluded that much of the focus in Bonn had “shift[ed] to efforts outside diplomatic talks – raising questions about the future of global climate negotiations”.
‘ATTACKING SCIENCE’: Agence France-Presse reported on the EU, Switzerland and “dozens of developing nations” warning of “attacks on science” by a “small group of fossil-fuels interests” in Bonn. Table Briefings explained that “the 1.5C target is increasingly being challenged” and the role of the UN climate-science panel – the Intergovernmental Panel on Climate Change (IPCC) – in an upcoming assessment of global climate progress “remains controversial”. See Carbon Brief’s full write-up of the talks for more detail.
US-Iran deal
PRICE DROP: The US and Iran announced that they have reached an interim agreement to halt the war and reopen the strait of Hormuz, reported Bloomberg. Oil prices have fallen, as the “long-awaited deal” began the process of “eas[ing]” the global energy crisis triggered by the conflict, according to the New York Times. The Associated Press noted that high fuel prices will “likely outlast the Iran war”.
‘OIL GLUT’: The Financial Times reported that the International Energy Agency (IEA) has forecast a “glut of oil” emerging next year, if the peace deal holds. The IEA said this would allow countries to build new strategic reserves, as they “review their energy strategies and policies in response to the crisis”, according to Reuters.
‘NEW ERA’: Agence France-Presse reported that oil and gas companies have “few illusions about a return to normal for the Gulf energy industry after more than three months of blockage”. One analyst told the newswire that the war “showed the oil and gas industry that Hormuz risk is no longer just a geopolitical headline”.
Around the world
- OCEAN MONITOR: The Trump administration is “abandoning its plan” to dismantle a $368m ocean monitoring system key for tracking climate change after a “bipartisan backlash on Capitol Hill”, reported the New York Times.
- CORAL HAVEN: The New York Times covered preliminary research, presented at the Our Ocean Conference in Kenya, suggesting there could be three times as many “coral refugia” – where corals are relatively safe from climate change – than previously thought.
- BAD CREDIT: Down to Earth reported that the first carbon credits issued under the Paris Agreement’s new Article 6.4 mechanism are “facing scrutiny over alleged links to institutions controlled by Myanmar’s military junta”.
- OIL BACKTRACK: Reuters reported that oil-and-gas company Equinor has dropped a renewable-energy target and scaled back clean investments, while another Reuters story noted that Shell is selling off its offshore wind assets.
1.1 billion
The number of children facing “at least three overlapping climate hazards”, according to a new Unicef report covered by Agence France-Presse.

Captured
The more than 2m battery electric vehicles (BEVs), 1m “plug-in” hybrids (PHEVs) and 100,000 electric vans on UK roads are already saving drivers a total of around £3bn a year, according to new Carbon Brief analysis. This amounts to savings of more than £1,100 a year in fuel costs for each BEV driver in the UK. The analysis comes amid reports in UK media this week that the government is considering “watering down” its EV sales targets.
Spotlight
Oceans rising at UN climate talks
The state of the world’s oceans is inextricably linked to the changing climate – and many delegates at UN climate talks want to see more focus on this issue, reports Carbon Brief.
Oceans are often described as the world’s “greatest ally” against climate change – absorbing 30% of carbon dioxide (CO2) emissions and most of the heat generated by those emissions.
They are also the site of important climate solutions, such as huge offshore windfarms and the shipping industry’s transition to cleaner fuels.
At the same time, the oceans themselves present a growing danger to coastal communities and sea life due to sea level rise, marine heatwaves and ocean acidification.
These diverse issues have led to growing calls within the UN climate process for more focus on oceans. During climate negotiations this week in Bonn – known as SB64 – nations and civil society had a chance to air these views during an “ocean and climate change dialogue”.
‘Elevate action’
Oceans first entered UN climate outcomes in 2019, when the final COP25 negotiated text requested a new “dialogue” on “the ocean and climate change to consider how to strengthen mitigation and adaptation action”.
The following years saw this dialogue established as an annual event. However, the political weight of these discussions has been limited.
COP31 is being co-led by Turkey and Australia, but with Pacific islands playing a supporting role. These small islands sometimes self-identify as “large ocean states”, stressing the ocean’s centrality in their societies.
In Bonn, figures from across the presidency threw their weight behind this issue. Chris Bowen, an Australian minister and incoming COP31 “president of negotiations”, told attendees:
“Australia, Turkey and the Pacific see an important opportunity to elevate ocean-based climate action.”
Strategies and finance
The two-day dialogue in Bonn involved a series of panels, statements and breakout groups.
One of the main topics was how oceans are integrated into national climate plans under the Paris Agreement, known as “nationally determined contributions” (NDCs).
Three-quarters of the latest round of NDCs mention oceans, with conservation of “blue carbon” ecosystems the most frequently described action. (Landscapes such as mangroves can both absorb CO2 and protect coastal areas.)
Delegates also discussed alignment with the UN biodiversity process, as well as ocean finance, which currently makes up less than 1% of all climate finance.
(As discussions were taking place in Bonn, country officials also gathered in Mombasa, Kenya for the 11th Our Ocean Conference. Carbon Brief’s associate editor Giuliana Viglione attended the conference and will publish a full summary shortly.)
Developing countries were clear that many of the ocean-related actions in their NDCs would depend on receiving more financial support.
‘Political momentum’
With the backing of the COP31 presidency, delegates were hopeful about where this year’s dialogue could lead.
Charles Hamilton, an advisor for the Bahamas who spoke for the Alliance of Small Island States (AOSIS) in the dialogue, told Carbon Brief that island representatives “are not traveling thousands of miles to just talk and pat ourselves on the back”. He added:
“A dialogue that just remains a dialogue is just more talk – no action.”
Given that, he said “discussions in the dialogue must move into COP decisions and the decisions must be actioned”, noting the importance of finance.
Marina Corrêa, oceans lead at WWF-Brazil, pointed to an upcoming UN climate change Standing Committee on Finance forum as a space to ramp up pressure on ocean finance.
More broadly, she wanted to see the presidencies translate their support into a “leader-level ocean initiative” that could “mainstream” oceans across negotiations.
“We have a really interesting opportunity, in terms of political momentum,” Corrêa told Carbon Brief.
