Key developments

Fertiliser disruption in Middle East

FOOD RISKS: The US-Israel war on Iran is “disrupting” the production and export of synthetic fertilisers, reported the Financial Times, which could lead to food price increases. The newspaper noted that the Strait of Hormuz passage, which remains at a near-standstill, is a “crucial shipping route for exports” including urea, sulphur and ammonia – all used in fertilisers. The Guardian noted: “Roughly half of global food production depends on synthetic nitrogen and crop yields would fall without fertiliser.”

PLANT FOOD: The fertiliser situation is “especially troubling for farmers in the northern hemisphere” who are beginning to plant their spring crops, said the New York Times. An article in the Conversation said that “even modest reductions in nitrogen use can produce disproportionately large declines in yield”. Elsewhere, a Carbon Brief Q&A looked at the impacts of the war on the energy transition and climate action.

WATER WORRIES: Water – already in short supply in Iran, where long-running droughts have been exacerbated by climate change – has come into renewed focus in the conflict. Bloomberg columnist Javier Blas said water could become the “geopolitical commodity that decides the war”. Desalination plants came “under attack” in Iran and Bahrain, reported the New York Times. These types of plants offer the “only reliable water source for millions across the Arabian Peninsula”, said the Independent.

Negotiations of seabed mining resume

LEGAL BRIEF: The International Seabed Authority (ISA)’s Legal and Technical Commission held a meeting in late February, where they made “progress” in reviewing applications for deep-sea mining exploration and the development of regional environmental management plans, according to an ISA press release. The ISA’s 36-member governing council is currently in Jamaica for a two-week meeting to discuss the future of deep-sea mining in areas beyond national jurisdiction.

NEW RULEBOOK: The New York Times interviewed Leticia Carvalho, head of the ISA, who said the long-awaited deep-sea mining rulebook should be finalised by the end of this year. She said the Trump administration’s push for deep-sea mining is making such an agreement more urgent than ever. However, Grist said that an advocate from French Polynesia said that he does not expect the regulations to be finalised this year, as there are several agreements and discussions pending, including on environmental protections.

INDIGENOUS DEMANDS: Indigenous advocates, who have long worked for their rights to be included in seabed mining regulations, are “bracing for the outcome” of the Jamaica meeting, reported Grist. Some fear that the incorporation of Indigenous rights into those regulations will be dismissed, as has happened previously, said the outlet.

News and views

LAWS OF NATURE: The EU court of justice fined Portugal €10m (£8.7m) for “failing to comply with environmental laws that require it to protect biodiversity”, according to the Guardian. The newspaper said the country will be penalised until the 55 unprotected sites are protected under EU biodiversity law.
BURIED REPORT UNCOVERED: Last week, a group of scientists and experts released a draft assessment about the health of nature in the US that had been cancelled by the Trump administration last year, according to the New York Times. The report is “grim, but shot through with bright spots and possibility”, said the outlet.
‘BI-OCEANIC’ RAIL: Experts are concerned about the potential social and environmental impacts of a train “mega-project” between Peru and Brazil, reported Mongabay. One researcher told the outlet that the possible rail routes, which cross through the Amazon rainforest, could cause “colossal environmental damage”.
CLIMATE COOPERATION: India and Nepal signed an agreement to strengthen transboundary cooperation in topics such as climate change, forests and biodiversity conservation, reported the New Indian Express. The collaboration will include the restoration of wildlife corridors and knowledge exchanges, the outlet said.
REPORT CARD: Carbon Brief analysis showed that half of the world’s countries met a 28 February UN deadline to report on national efforts to tackle nature loss. As of 10 March, 123 countries out of 196 had submitted their national reports, which will inform nature negotiations in Armenia later this year.
CROP LOSSES: Down To Earth covered a study finding that a “deadly” virus is threatening cassava crops in parts of Africa, partly due to climate change. Meanwhile, Carbon Brief updated an interactive map showing 140 cases of crops being destroyed by heat, drought, floods and other extremes in the past three years.

Spotlight

Women farmers in a warmer and unequal world

International Women’s Day occurs every year on 8 March. Carbon Brief explores the impacts of climate change and gender inequality on women farmers and how they are adapting to a warming planet.

Women farmers play an essential role in global food supply.

According to a report from the UN Food and Agriculture Organization (FAO), around 36% of working women in 2019 were engaged in agri-food systems. On average, they earned 18% less than men in that sector.

The report found that women working in agriculture tend to do so “under highly unfavourable conditions”, including in the face of “climate-induced weather shocks”.

Typically, women farmers are concentrated in the poorest countries, produce less-lucrative crops and are often unpaid family workers or casual workers in agriculture, the report said.

Vulnerabilities

Research has shown that women farmers are more vulnerable to the impacts of climate change than men.

In Africa and Asia, for example, a 2023 study found that “climate hazards and stressors…tend to negatively affect women [in agri-food systems] more than men”. This is because gender inequality – in the form of discriminatory gender roles or unequal access to resources – is most pronounced in those regions, the study said.

A 2025 study focusing specifically on the Sleman region of Indonesia found that 63% of women farmers suffered from food insecurity due to vulnerability to climate change. This arises from both frequent exposure to drought and low ability to respond to climate impacts, the study explained.

Geraldine García Uribe has been a farmer at the U Neek’ Lu’um agroecology school in Yucatán, Mexico, since 2023. She told Carbon Brief:

“When you have fixed [planting and harvesting] cycles and you start to see changes in the climate – longer droughts or changes in rainfall patterns – plants take longer to grow and pests start to arrive, and that affects the farmers’ pockets and the livelihoods of [their] families.”

She added that women farmers also face inequalities when it comes to deciding how to manage agricultural lands:

“When government support comes, they take [women] less into account because, in general, there are more men present at meetings.”

Adaptation needs

Women farmers face constraints that make them less able to adapt to climate change, according to the FAO report. For example, the working hours of women farmers “decline less than men’s during climate shocks such as heat stress”, said the report.

Josselyn Vega has been farming on her own agroecology farm in Cotopaxi, Ecuador, for three decades. In the Andean region comprising Ecuador, Bolivia and Peru, droughts and floods are frequent, but there are also frosts which, although expected to decrease with climate change, cause crop losses and can have a “drastic” impact on the local economy, according to the Adaptation Fund.

Vega told Carbon Brief that her farm has used “living barriers” to help protect from weather extremes:

“Living barriers are a wall of forest and fruit trees [that] block the wind and prevent drought and frost from passing through.”

The 2023 study recommended that transforming agri-food systems into fairer and more sustainable ones requires reducing and preventing gender inequality.

At the international level, countries have an agreement to implement climate solutions that take women into account, including women farmers. At the most recent UN climate negotiations in Belém, Brazil, countries adopted a new gender action plan, which will last nine years and encourages countries to develop climate policies and plans with a gender perspective.

Vega said that public policies are needed to empower women farmers and ensure that they are included in decision-making. She told Carbon Brief:

“We need to benefit from something that encourages us to continue planting and caring for the land.”

Revealed: Scientists tell Colombia fossil-fuel transition summit to ‘halt new expansion’

Published

Countries attending a first-of-its-kind fossil-fuel summit have been asked to consider “action recommendations” such as “halting all new fossil-fuel expansion” and “reject[ing] gas as a bridging fuel”, according to a preliminary scientific report seen by Carbon Brief.

Around 50 nations will gather in Santa Marta, Colombia from 24-29 April to debate ways to “transition away” from fossil fuels, in the face of worsening climate change and sky-high oil prices.

The talks come after a large group of nations campaigned for, but ultimately failed, to get all countries to formally agree to a “roadmap” away from fossil fuels at the COP30 climate summit in Brazil in November.

The nations gathering in Santa Marta for the summit co-hosted by Colombia and the Netherlands, call themselves the “coalition of the willing”.

Ahead of country officials arriving in Santa Marta, a global group of academics will gather in the city this week to present and discuss the latest scientific evidence on fossil-fuel phaseout, which will then inform debate among policymakers.

A preliminary scientific “synthesis report” circulated to governments attending the talks and seen by Carbon Brief offers 12 “action insights” for countries to consider, along with a wide range of “action recommendations”.

These recommendations range from “phase out subsidies on fossil-fuel production and consumption” to “kick-start a forum to develop a legal framework to ban fossil-fuel advertisements”.

‘Rapid’ assessment

The preliminary scientific report seen by Carbon Brief – titled, “Action insights for the Santa Marta process” – is the result of some rapid work by an “ad-hoc” group of around 24 scientists.

It is designed to present governments attending the talks with concrete and actionable recommendations for transitioning away from fossil fuels.

The preliminary version, which includes recommendations such as “halting all new fossil fuel expansion”, has already been circulated to governments, with a view that this could help them to prepare for the talks in advance.

It will be further debated and refined by scientists attending the academic segment of the Santa Marta talks, before a final version is made public towards the end of April, Carbon Brief understands.

The process to produce the report began shortly after the conclusion of the COP30 climate summit in Brazil in November, explains its lead author, Dr Friedrich Bohn, a research scientist and co-founder of the Earth Resilience Institute in Germany. He tells Carbon Brief:

“When [Brazil] announced there would be a Santa Marta conference led by Colombia and the Netherlands, I was sitting listening with a small group of scientists. We thought: ‘This is great news, but it should be supported by scientific expertise.’”

One of the members of Bohn’s group had a pre-existing relationship with the Colombian government, allowing a dialogue to quickly be established, he continues:

“In the beginning, the idea was to just write a peer-reviewed paper. But, because of this close connection to the Colombian government and some feedback from them, the synthesis paper evolved.”

The report came out of a “very rapidly evolved process” that relied on the “goodwill” and “enthusiasm” of the academics involved, adds coordinating author Prof Frank Jotzo, a professor of climate change economics at Australian National University. (Jotzo is a former Carbon Brief contributing editor.) He tells Carbon Brief:

“It’s an attempt to get broad coverage on relevant topics from researchers with good expertise and reputation.”

The group of 24 scientists involved spent around two months compiling the “action insights” for the report, drawing on their expertise and the latest available research, says Jotzo.

Given the rapid nature of the report, it does not aim to be “completist”, has not been externally reviewed and did not follow a stringent process for author selection comparable to that used by Intergovernmental Panel on Climate Change (IPCC) reports, he adds.

The contributors to the report currently skew to the global north and include more men than women, adds Bohn.

‘Direct guidance’

In a departure from IPCC reports, the preliminary Santa Marta synthesis report offers “very direct guidance to action”, says Jotzo.

The report lists 12 “action insights”, each with three “action recommendations”. (The list was cut down from a shortlist of about 40-50 insights, Carbon Brief understands.)

One of the most striking in the draft is “action insight 5”, which says:

“Take immediate measures to prevent future emissions. Ban new fossil infrastructure, mandate deep methane cuts, accelerate electrification and inscribe fossil-fuel phase-down targets in NDCs [nationally determined contributions] and clean-energy pathways support to low and middle income countries (LMICs).”

The accompanying three “action recommendations” include “halting all new fossil-fuel extraction and infrastructure projects ahead of a final investment decision”, “implementing deep, legally binding methane cuts in the energy sector” and “inscrib[ing] targets for fossil-fuel phase down, electrification and green exports in NDCs”.

(The draft report includes multiple references to “phasing out” and “phasing down” fossil fuels, rather than the “transition away from fossil fuels” language that was, ultimately, agreed by countries at the COP28 UN climate talks in Dubai in 2023.)

Another action insight says “public support for climate action is broadly underestimated and undermined by interest groups, but it can be strengthened by debunking greenwashing narratives”.

One recommendation for this insight is that nations “reject natural gas as a bridging technology and CCS [carbon capture and storage] techniques as scalable compensation”.

In a letter introducing the report to governments and civil society, the scientists note that making direct recommendations is a “challenge for our community”, but added:

“However, in the spirit of a constructive collaboration between science and policymaking, we allowed ourselves to identify some potential courses of action that our community would recommend for each particular issue – and we invite you to weigh these against your own circumstances and pick up whatever seems most useful for you and your colleagues.”

The prescriptiveness of the recommendations – something strictly prohibited in IPCC reports – was an explicit request from the Colombian government, Bohn says:

“The idea of actionable recommendations was introduced by the Colombian government.

“There was some discussion within the team about this. It’s a tricky area when you leave science and move to consultation. Therefore, we agreed, in the end, to call them ‘actionable recommendations’ and to make them as precise as possible, from the scientific perspective.”

Jotzo, a veteran of the IPCC process, tells Carbon Brief that it was “very liberating” to work on a report with a “free-form process”:

“The bulk of policy-related research is very readily deployed to recommendations pointing out what countries could do. The IPCC process, for example, just doesn’t allow that. As far as the summary for policymakers in the IPCC is concerned, it will usually be governments that filter out anything that could be interpreted as a specific recommendation.”

He adds that the hope is that some of the action insights might be reflected in the high-level segment of the Santa Marta conference:

“No one is under any illusions that governments will walk away from the Santa Marta conference and will have made a decision to implement recommendations one, seven and nine – or something like that. But it is a chance to insert directly applicable action points into national and plurilateral policy agendas.”

Colombia calling

The preliminary report will be further debated and refined by scientists attending the “pre-academic segment” of the Santa Marta talks.

This is taking place from 24-26 April, ahead of the “high-level segment” involving ministers and other policymakers from 28-29 April.

The pre-academic segment will also separately see the launch of a new advisory panel on fossil-fuel transition and a scientifically led roadmap for how Colombia can transition away from fossil fuels, Carbon Brief understands.

The high-level segment is expected to be attended by representatives from around 50 countries, including COP31 host Turkey and major oil-and-gas producers such as the UK, Canada, Australia, Brazil and Norway.

Countries expected to attend account for one-third of global fossil-fuel demand and one-fifth of global production, according to the Colombian government.

At the end of the conference, countries are due to release a report featuring a “menu of solutions” for transitioning away from fossil fuels, according to Colombia’s environment minister Irene Vélez Torres.

This report is in turn set to inform a global “roadmap” on transitioning away from fossil fuels being developed by the Brazilian COP30 presidency, which is due to be presented at COP31 in Turkey this November.

The Brazilian COP30 presidency offered to bring forward a “voluntary” fossil-fuel transition “roadmap” outside of the official COP process, after countries failed to formally agree to one during negotiations in Belém.
