COP30: Governments must empower forest communities to keep fossil fuels underground

Source: The Conversation – Canada – By Philippe Le Billon, Professor, Geography Department and School of Public Policy & Global Affairs, University of British Columbia

Brazilian President Luiz Inácio Lula da Silva has dubbed COP30 the forest COP. Taking place in Belém, a large urban centre in the Amazon, this choice signals a welcome shift from the capital cities of petro-states to the heart of the world’s most bio-diverse rainforest.

Yet, even as Belém hosts global climate negotiators, the Amazon and its coastline are under renewed pressure. While the spotlight is on protecting trees, new oil concessions are being awarded to keep rigs pumping.

On Nov. 11, dozens of Indigenous protesters forced their way into the COP30 venue demanding an end to industrial development in the Amazon. Indigenous leaders attending COP30 are demanding more say in how forests are managed.

Amid this tension, a new financial initiative has emerged as the potential solution: the Tropical Forest Forever Facility (TFFF). Managed by the World Bank as a multilateral trust fund, it would mobilize US$125 billion from public and private investors to reward forested countries for keeping their forests standing — forever.

The pitch is seductive — save forests, earn profits and mitigate climate change all at once. But the proposal raises two questions that demand scrutiny: Will this scheme actually make a major difference for the climate, and how will it impact communities who live in forests?

From the Amazon, Indigenous Peoples offer new compass to navigate climate change


Protecting trees

The first question is easier to tackle. Yes, tropical forests store immense amounts of carbon so protecting them is vital. But this contribution is largely contingent on keeping global temperature below 2 C and is dwarfed by the emissions risked if fossil fuels buried beneath those same forests are extracted and burned.

Out of the 74 countries with TFFF-qualifying forests, 68 countries have fossil fuel deposits within them. In total, according to a study by the NGO Leave It In The Ground, there would be some 317 billion tonnes of potential carbon dioxide emissions from recoverable reserves and more than 4.6 trillion tonnes if all deposits were exploited.

Nearly all of it is concentrated in just three countries: China, India and Indonesia. To be truly effective, forest protection must come with a firm commitment: no fossil fuel extraction underneath.

To be equitable, a similar scheme must cover non-TFFF countries, and in particular those with boreal forests covering major fossil fuel deposits, namely in Canada and Russia.

That means prioritizing forests located above fossil fuel reserves and ensuring they remain completely off-limits to exploitation.

For this to happen, countries must make binding commitments, investors must accept lower-risk but longer-term returns and local communities must hold forest tenure rights that cannot be overridden by state ownership of subsoil resources. It’s a tall order — but without such a framework, the “forever forest” concept risks becoming just another limited climate solution.

The term forever forests evokes the advertising slogan of diamond company De Beers — “A Diamond is forever” — and reveals a similar logic: to turn nature into financial assets. A more fitting concept might be what fisheries economist Rashid Sumaila would call the infinity forest — a forest that, like fish stocks, is renewable when soundly managed as a common good.

Many of the world’s forests are not untouched wildernesses but co-created landscapes, shaped through millennia of Indigenous and local stewardship. The Amazon, for instance, is a complex social biome, nurtured through practices such as controlled burning, seed dispersal and farming.

While not all traditional practices are benign, archaeological and ecological evidence shows that many Indigenous and peasant communities have managed forests sustainably — often more effectively than state-led conservation programs and with major implications for biodiversity protection.

In fact, many studies show that biodiversity conservation is more effective in territories governed by Indigenous peoples than in state-managed protected areas.

A financial trap for forest communities

Beyond its likely ineffectiveness for the climate, the TFFF could also have devastating consequences for forest communities. Under Brazil’s current proposal, countries would receive around US$4 for every hectare of protected forest, with 80 cents trickling down to local communities.

But they would be fined US$400 per hectare for any deforestation. This creates a dangerous dynamic: states will crack down on small-scale forest use by local people while giving free rein to industries — such as oil — that generate far higher returns.

In effect, the scheme risks criminalizing traditional forest practices — from small-scale clearing to hunting or gathering — that have sustained these ecosystems for centuries.

As governments seek to avoid penalties, forest communities could face exclusion, forced resettlement or even violence, echoing a long history of displacement caused by “conservation” projects and carbon offset schemes such as REDD+.

Financializing the forest’s future

This brings us to the Indigenous and forest defenders who disrupted COP30 events on Nov. 11. Their protest highlighted the real danger behind the TFFF: the financialization of Indigenous territories.

The scheme does nothing to prevent oil and gas extraction beneath forest lands. What were once commons could become commodities promising investors lucrative returns.

In short, “forever forests” may deliver forever profits — not so much for the people who protect them as for those who exploit their value. This is, bluntly, a new form of green colonialism — a profitable appropriation of the forest’s future.

If the TFFF goes ahead, it must first grant some degree of self-government to Indigenous forest communities — as Colombia recently did — and explicitly prohibit fossil fuel extraction in protected forests.

Investors should pay a premium for forests covering fossil fuel reserves, and both state and community rights must be rebalanced to make no-go zones truly binding. In this way, “forever forests” can become territories of life — not assets of accumulation.

Ultimately, no financial mechanism will save the world’s forests unless it also saves the people who depend on them, and the carbon that must remain buried beneath.

The path to a livable planet runs not through markets or bonds, but through justice: recognition of forest community stewardship and a global commitment to keep fossil fuels in the ground.

À moins de trois mois des JO d’hiver, quelles attentes environnementales ?

Source: The Conversation – in French – By Alizée Pillod, Doctorante en science politique, Université de Montréal

L’Italie s’apprête à accueillir cet hiver la 25e édition des Jeux olympiques d’hiver, prévus du 6 au 22 février 2026, suivis des Jeux paralympiques, qui se tiendront du 6 au 15 mars.

Après l’effervescence des Jeux de Paris, lesquels avaient placé la durabilité au cœur de leur stratégie de planification, ceux de Milan seront déterminants pour savoir si l’on assiste véritablement à un changement de paradigme au sein du mouvement olympique.

À moins de 100 jours de l’échéance, le comité organisateur des Jeux de Milan-Cortina sera-t-il capable de tenir sa promesse verte ?

Doctorante en science politique à l’Université de Montréal, mes travaux portent à la fois sur la communication climatique et l’élaboration de politiques environnementales, y compris dans le secteur du sport.

Les Jeux d’hiver dans la tourmente climatique

Tout d’abord, il faut souligner que peu de secteurs dépendent autant des conditions météorologiques que celui du sport.

Avec la crise climatique, la pratique sportive, en particulier celle des sports d’hiver, devient de plus en plus difficile. L’annulation de la Coupe du monde de ski alpin au Mont Tremblant l’an dernier, faute de neige, en est un exemple frappant.

Selon une étude de l’Université Waterloo, d’ici 2050, seuls 10 anciens sites olympiques demeureront viables pour accueillir de futurs Jeux d’hiver. À l’horizon 2080, ce nombre pourrait chuter à seulement 6.

Parallèlement, l’organisation de mégaévènements sportifs tels que les Jeux, engendre une empreinte carbone et environnementale considérable.

Bien que généralement plus modestes que celles estivales, les éditions hivernales des Jeux ont fait l’objet de nombreuses controverses écologiques, en lien notamment avec la destruction de réserves naturelles jusque-là préservées.

La plus récente, Pékin 2022, a conduit à l’abattage de plus de 20,000 arbres ancestraux pour permettre l’expansion du domaine skiable et la construction d’infrastructures en tout genre, telles que des routes d’accès, des stationnements ou encore des sites d’hébergement.

Le sport de haut niveau se trouve ainsi pris dans une relation à la fois de dépendance et de contribution au réchauffement climatique.

Les Agendas 20 et 20+5 comme nouveaux standards

Conscient de ces défis, le Comité international olympique (CIO) a adopté ces dernières années plusieurs politiques visant à réduire l’empreinte des Jeux, comme l’Agenda 20, dont les objectifs stratégiques ont été réitérés en 2021 avec l’Agenda 20+5.

Après Paris 2024, les Jeux de Milan-Cortina seront les premiers Jeux d’hiver à devoir respecter ces exigences.

Parmi les intentions formulées figurent la volonté de promouvoir des Jeux durables et de faire de ceux-ci un tremplin pour l’atteinte des objectifs du développement durable de l’ONU.

Pour cela, le CIO demande désormais aux villes hôtes de réduire leurs émissions de CO₂ et met de l’avant la notion d’héritage, en encourageant la réutilisation de sites déjà existants et la reconversion de ceux-ci une fois l’évènement terminé.

Milan-Cortina sur la piste verte

Heureusement pour nous, il semble que le comité organisateur italien ait décidé de faire de la lutte contre le réchauffement climatique un élément central de son plan stratégique. Dès le départ, celui-ci a mis en place un processus rigoureux d’évaluation de ses émissions de gaz à effet de serre.

Dans son deuxième rapport sur sa stratégie de durabilité, publié en septembre 2025, le comité a également présenté plusieurs mesures visant à réduire davantage l’empreinte carbone de l’événement.

Parmi les initiatives phares, le comité s’est notamment engagé à utiliser une alimentation énergétique 100 % renouvelable et à limiter le gaspillage alimentaire en redistribuant l’intégralité des surplus à des organismes caritatifs locaux. Dans une volonté d’encourager l’économie circulaire, plus de 20 000 équipements issus des Jeux de Paris ont aussi été rachetés.

Du côté des infrastructures, à l’instar de ce qui avait été fait à Paris, l’accent est à nouveau mis sur la réutilisation des installations existantes et sur le recours à des structures temporaires qui seront démantelées après les Jeux. Au total, près de 90 % des sites entreront dans cette catégorie.

Les quelques nouvelles constructions permanentes deviendront des centres d’entraînement pour la future élite sportive italienne, ou bien seront transformées pour d’autres usages. Tout comme celui de Paris, le nouveau village olympique à Milan deviendra, par exemple, une résidence universitaire.

Le plan comprend également des mesures d’adaptation. Avec le réchauffement climatique, l’enneigement naturel se fait de plus en plus rare et le recours à la neige artificielle devient la nouvelle norme pour continuer d’offrir aux athlètes des conditions de performances optimales. Dans ce contexte, le comité organisateur a décidé de moderniser ses systèmes de production de neige artificielle afin de pouvoir répondre plus efficacement aux besoins en cas de températures anormalement élevées cet hiver.

Un plan italien ambitieux, non pas sans défauts

Si le plan semble rassurant sur papier, sa mise en œuvre comporte néanmoins son lot de défis.

Au-delà des retards chroniques dans l’avancement des travaux et des dépassements budgétaires colossaux (avec des dépenses multipliées au moins par deux par rapport au budget initial), la construction de nouvelles infrastructures en montagne a nécessairement une empreinte environnementale élevée.

Rappelons que les Jeux de Milan-Cortina se dérouleront sur des sites répartis dans quatre zones du nord de l’Italie : Milan, Cortina, la Valtellina et le Val di Fiemme. Ensemble, ces sites couvrent un territoire de plus de 20 000 kilomètres carrés, ce qui en fera les Jeux les plus dispersés de l’histoire. Ainsi, il n’y aura pas un mais plutôt six sites de villégiature pour les athlètes (oui, vous avez bien lu !).

Cela explique sans doute pourquoi la majeure partie du budget est allouée au développement des transports publics, notamment du réseau ferroviaire, afin de faciliter les déplacements entre les différents sites. Les infrastructures sportives, quant à elles, représentent moins du quart du budget total.

De plus, certaines constructions ont fait polémiques. La toute nouvelle piste de bobsleigh à Cortina a, par exemple, été fortement critiquée, du fait qu’elle a entraîné l’abattage de plusieurs centaines d’arbres. Même si l’on reste loin des chiffres observés à Pékin, il n’en demeure pas moins que l’organisation des Jeux perturbe la biodiversité locale.

En ce qui concerne les installations temporaires, le comité s’est engagé à restaurer les écosystèmes et, plus largement, à compenser l’ensemble des émissions résiduelles, notamment par l’achat de crédits carbone. Les plus pessimistes diront cependant que ce qui a été détruit ne pourra jamais être entièrement restauré, et qu’aucune compensation financière ou écologique ne saurait réellement en effacer l’impact.

En termes d’adaptation, notons que la production de neige artificielle, même si optimisée, nécessite beaucoup d’eau et d’énergie, en plus de dégrader la qualité des sols. Ainsi, cette solution, censée pallier les effets du réchauffement, finit paradoxalement par y contribuer. D’où l’importance de mieux penser les solutions d’adaptation.

Enfin, les habitants redoutent un effet d’embourgeoisement. À Milan, l’édification du village olympique a entraîné l’expulsion de résidents, et les loyers prévus une fois le site reconverti en résidence universitaire sont jugés trop élevés. Ainsi, dans une perspective de justice sociale, on peut se demander à qui profiteront réellement les nouvelles installations à plus long terme.

Peut-on parler d’un vrai tournant ?

Dans l’ensemble, la stratégie de Milan-Cortina montre une réelle évolution dans la façon de penser la durabilité des Jeux d’hiver. Les organisateurs ont appris des éditions précédentes et proposent désormais des approches d’autant plus innovantes.

Bien que les émissions de gaz à effet de serre anticipées soient moins élevées qu’à Pékin ou à Pyeongchang, celles de Milan-Cortina demeurent estimées à près d’un million de tonnes de CO₂ équivalent. Dans ce contexte, il reste à espérer que le comité parvienne véritablement à mettre en œuvre l’ensemble des mesures prévues afin d’en compenser la plus grande part possible.

Par ailleurs, la prochaine édition des Jeux d’hiver aura lieu, elle aussi, dans les Alpes, mais cette fois en territoire français. Le tout nouveau comité organisateur des Jeux de 2030 suit sans doute avec attention les choix faits du côté italien, conscient des défis climatiques croissants qui l’attendent.

D’ici là, on peut compter sur les athlètes et para-athlètes, lesquels sont déjà à pied d’œuvre au moment où j’écris ces lignes, pour nous éblouir encore, ne serait-ce le temps d’un instant.

Ukraine: energy corruption scandal threatens to derail Zelensky’s government and undermine its war effort

Source: The Conversation – UK – By Stefan Wolff, Professor of International Security, University of Birmingham

The latest corruption scandal that has engulfed Ukraine could not have come at a worse time or in a more delicate sector of the economy for the increasingly embattled government of Volodymyr Zelensky.

Ukraine’s military is now clearly on the back foot in several key sectors of the frontline. Meanwhile, Russia’s campaign to devastate Ukraine’s energy sector is putting enormous pressure on the country’s infrastructure and bringing increasing hardship for ordinary Ukrainians as winter approaches.

The fact that the latest corruption scandal involves the energy sector is, therefore, particularly damaging to the government and public morale.

Ukraine’s independent anti-corruption agencies have just released the findings of Operation Midas, a 15-month investigation into Energoatom, which is the state-owned operator of all of Ukraine’s nuclear power plants. With a total capacity of almost 14,000 megawatts, Energoatom is the largest electricity producer in Ukraine.

Anti-corruption investigators allege a large kickback scheme of between 10% and 15% of the value of supplier contracts, amounting to about US$100 million (£76 million). Raids were carried out in 70 locations around the country on November 10. Seven people have been charged and five are in custody.

The mastermind of the corrupt scheme is alleged to be Timur Mindich a businessman and film producer, who hastily fled Ukraine a day before the raids. What makes this very dangerous for Zelensky is that Mindich is the co-owner, with the Ukrainian president, of Kvartal 95 Studio. Kvartal is the media platform on which Zelensky established his pre-presidential fame as a comedian.

Harry Boone/X

The scandal, therefore, once again involves very close allies of the president. It risks tainting by association. But it also leaves him open to questions of whether he could havacting sooner about the allegations.

But the way in which this latest scandal unfolded also indicates that it is the manifestation of a much deeper conflict going on behind the scenes between elite groups vying for control of the last valuable state asset – the energy sector.

Smear campaigns

It’s the latest in a chain of events that goes back to the summer months, when Zelensky’s Servant of the People parliamentary faction tried to terminate the independence of Ukraine’s anti-corruption agencies. Mass protests by young Ukrainians forced the government to backtrack on the decision.

At this point, rumours about the existence of secretly taped conversations involving Mindich began to circulate in the Ukrainian media. However, no details of the content of the conversations were released at time, leaving any allegations of corruption to the realm of speculation.

As the government came under increasing pressure after massive Russian air strikes against the energy sector on October 10 which left Ukraine’s population without electricity for almost an entire day, mud-slinging began in earnest. Attention focused on Volodymyr Kudrytsky, the former head of Ukrenergo, the main operator of Ukraine’s electricity grid.

Kudrytsky, an outspoken figure in Ukraine’s pro-western and anti-corruption civil society, was detained on October 28 on suspicion of fraud relating to his alleged involvement in a 2018 plot to embezzle the equivalent of $1.6 million from state funds. The investigation against him was conducted by State Audit Service of Ukraine and State Bureau of Investigation, which are directly subordinate to Zelensky.

He has robustly defended his record against what he alleged were politically motivated attacks designed to shift the blame for the devastation of Ukraine’s energy grid by Russia’s air campaign away from the government.

While Kudrytsky has been released on bail, the case against him remains live.

Power struggle

Whatever their outcome in legal terms, the rumours circulating against Mindich and the attacks against Kudrytsky appear, for now at least, to be classic information campaigns aimed at assassinating reputations and damaging the people and agendas associated with them.

As they pit pro- and anti-Zelensky camps in Ukraine’s elites against each other, the latest corruption revelations reveal a power struggle over who controls the state’s most valuable assets and the levers of power in Ukraine. If Zelensky’s enemies cannot remove him from power, then his ability to rule can be severely constrained by targeting close allies like Mindich.

Another of Zelensky’s top advisers, justice minister (formerly energy minister) German Galushchenko has also been suspended as a result of Operation Midas.

This elite infighting, which is engulfing a sector that is critical to Ukraine’s ability to continue resisting Russia’s aggression, is astounding in its disregard of the existential crisis engulfing Ukraine. While its outcome, for now, is unclear, several important conclusions can already be drawn from it.

The return to a competitive political process with freedom of speech, media, and association, which was suspended as a result of the war, is vital. Fears of playing into the hands of Russian propaganda by revealing corruption in Ukraine simply enable the corrupt officials to further abuse their power and damage the country’s prospects of prevailing against Russia.

More direct involvement of the EU and the US is needed in fighting corruption in Ukraine. Corruption reduces funds allocated for the war. But it also fuels public pessimism in donor countries about the effectiveness of their continuing support.

This corruption has been hugely damaging for recruitment to the armed forces. A recent survey found that 71% of Ukrainians believe the level of corruption has increased since Russia’s full-scale invasion in February 2022.

Monthly desertion rates from the army now stand roughly at the level of two-thirds of new recruits. That’s 21,000 deserters compared to 30,000 sign-ups. It’s not sustainable for Ukraine’s defence efforts – and is part of the reason for some of the recent setbacks at the frontline.

This is no longer about the country’s reputation and its prospects of European integration. Cleaning up Ukrainian politics – and being seen to do so – is now as essential for Ukraine’s survival as shoring up its air and ground defences against Russia.

Tolerating corruption is a luxury that Ukraine can no longer afford if it wants to survive as an independent country.

We studied the walking habits of young men in Cape Town and London – and debunked a myth

Source: The Conversation – Africa – By Bradley Rink, Associate Professor of Human Geography, University of the Western Cape

Being mobile means people can get access to opportunities and take part in economic and social life. Mobility, in all its forms, is critical for cities to thrive.

Recent studies highlight what most African city dwellers already know: walking is the main way of getting around, and essential for daily life. This is true for people who live in low-income neighbourhoods across the world. When people lack money for taxi, bus or train fares, walking becomes the only option even if the distances are great.

Yet, most African cities and many low-income neighbourhoods globally lack spaces for walking that are safe and appropriate.

While researchers place a lot of emphasis on road traffic, public transport and infrastructure, little attention has been paid to the importance of walking as a daily mobility strategy for low-income communities.

Even less is known about the walking experiences of young men. There often seems to be an assumption they are free to travel wherever and whenever they choose, that they’re invulnerable. But what are the realities they face on the street, and what we can learn from them?

We’re a team of human geographers and anthropologists working in collaboration with an international non-governmental organisation and a group of 12 peer researchers who are walkers: six from Cape Town and six from London. Our study aimed to learn more about the experiences of men like this, aged 18-35, in low-income urban neighbourhoods in South Africa and the UK.

We wanted to better understand issues of access and opportunity for communities that rely on walking. We also wanted to explore the potential of community-based research for improving lives.

Our findings revealed what expected cultural and gender norms often mask: young men in these communities often walk with great fear and trepidation.

The study

Our focus on young men was influenced by findings from an earlier study of young women in Cape Town. That study emphasised the particular concerns women have for the safety of their male counterparts who had to walk back home after accompanying the women to transit points.

We not only set out to foreground the walking experiences of young men; we also wanted to do research differently and with maximum potential impact for those involved. Peer research provides living knowledge, and also a chance to make meaningful change in transforming policy and practice. Peer researchers are, after all, experts in their own lives.

Through a five-day workshop we trained peer researchers in research methods, ethics and data collection. We gained an understanding of their communities through shared mapping exercises. The young men then set out to collect data independently, using mobility diaries. Each of them also interviewed at least 10 other young men in their community.

Although their specific neighbourhoods aren’t named for ethical reasons, the study areas were two township neigbhourhoods in Cape Town and various boroughs in the east end of London. They were strikingly similar when it came to a sense of everyday dangers from high rates of crime, violence and deprivation.

What we found

Young men in our study helped to undermine this myth of male invulnerability. They revealed how fear shapes their daily walking experiences and has an impact on their lives. As one participant said:

I’ve been a victim of crime: at that time I felt useless, weak and vulnerable.

More than this, their stories revealed how they use various tactics and strategies to stay safe. They walk with trusted others. They pay attention to their appearance and avoid displaying things like mobile phones and jewellery. They adjust their routes depending on the weather, darkness and the presence of criminal gangs.

As one participant put it:

I walk in the afternoon to the bus (to get to a job in a distant neighbourhood). It takes 10 minutes. It’s not safe … If I see criminals I pretend I’m tying my shoelace.

Other peer researchers confirmed that even the simple act of appearing to tie a shoelace allows you to survey the street while not looking scared and protecting masculine dignity. If it looks dangerous, they said, you can pretend you’ve forgotten something and run back the way you’ve come.

Our findings illustrate the complexity of daily walks. While mediating danger on the streets and navigating the precarities of urban life, our peer researchers also reflected on the pleasures of walking. They sometimes found joy and relief in walking:

I get to breathe fresh air instead of just sitting in the house … thinking about being unemployed and stuff. I get to see people and be healed.

Encountering the city on foot has benefits for physical and mental health.

Why this matters

Safe, reliable mobility is essential for lives and livelihoods in the city. Our study identified ways that community stakeholders can support safe walking and therefore help with access to economic and social opportunities.

Lifting the veil on men’s vulnerabilities allows community members and policy makers to understand the challenges across the gender spectrum.

But our research also matters because of how we went about it. The potential for change comes in the form of ongoing stakeholder engagement. Findings from the research were presented by the peer researchers themselves to community stakeholders and local government officials, people who have the capacity to improve infrastructure and safety.

Black and Latino homeowners in Philly face discrimination when appraisers assess their properties

Source: The Conversation – USA (2) – By Gregory Squires, Professor Emeritus of Sociology, George Washington University

Home appraisal bias contributes to racial wealth disparities and violates the Fair Housing Act.
Jeff Fusco/The Conversation U.S., CC BY-SA

For most families, owning a home is the primary way to accumulate wealth and transfer that wealth to future generations.

But in Philadelphia and other U.S. cities, studies have shown that if you live in a Black or Hispanic neighborhood, your home is more likely to be appraised below its market value when compared to homes in non-Hispanic white neighborhoods. This is called home appraisal bias.

An appraisal represents an expert opinion of the value of a home. It is determined by a licensed professional who applies industry standard rules and practices.

The appraisal is critical to securing a mortgage to purchase a home or to refinancing an existing mortgage. It can determine whether an applicant gets a mortgage and influence how much the mortgage costs. For example, if a borrower must take out a mortgage for more than 80% of a property’s value, they may be required to pay for private mortgage insurance in some cases. Getting the appraisal value right is key to ensuring that homebuyers and those seeking to refinance a mortgage can do so under fair and equal conditions.

We are two academics who study urban places and the people who live in them. Together, we have more than 80 years of experience working at federal civil rights agencies, teaching at research universities and consulting for the housing industry, city and state agencies, and nonprofits.

Most recently we have been working with Philadelphia Mayor Cherelle Parker on a plan to reduce racial bias in home appraisals in Philly.

Fair Housing Act of 1968

In 1968, President Lyndon Johnson signed the Fair Housing Act, which made it unlawful to deny housing based on race, color, religion or national origin. Congress added sex in 1974 and handicap and familial status in 1988.

The Fair Housing Act was passed just seven days after the assassination of the Rev. Martin Luther King Jr. and two months after the release of the Kerner Commission report. This federal report examined the causes of racial violence in the U.S. in the 1960s and concluded, “Our nation is moving toward two societies, one black, one white, separate and unequal.”

Passage of the Fair Housing Act did not end housing discrimination. But over the years, residential segregation has declined slowly, and the most egregious and overt discriminatory acts, such as cross burnings and blockbusting, rarely happen anymore.

In recent years, attention has focused on racial disparities in home valuation established by appraisals. This reflects, in part, some high-profile, public allegations of racial bias in appraising revealed through homeowners’ “whitewashing” of their homes.

Whitewashing describes how a Black homeowner who receives a low appraisal removes all signs that a Black person lives in a home, replaces family photos with photos of white people, and has a white friend at home when a second appraiser arrives, giving the impression that it is the home of a white family. Bias is revealed when the second appraisal produces a higher value than the first.

The fact that 94% of appraisers and assessors in the U.S. are white may be a contributing factor.

Appraisal discrimination is unfair, contributes to racial wealth disparities and violates the Fair Housing Act.

Home appraisal bias is a national issue

Multiple studies establish that homes in Black and brown neighborhoods across the U.S., all else equal, are valued less than comparable homes in white neighborhoods. Appraisal bias is just one factor in this, as are historical and contemporary redlining and real estate practices, individual choices and other factors.

One way to identify appraisal discrimination would be to compare how often appraisals are below agreed-upon sale prices in nonwhite neighborhoods compared to white neighborhoods. Our research has documented that appraisals themselves are sometimes biased representations of home values.

Nationally, the percentage of appraisals below the sale price is substantially greater in nonwhite neighborhoods than in white neighborhoods. There is no apparent reason that appraisals should be systematically higher or lower than sale prices in nonwhite or white neighborhoods.

It’s a Philly issue too

Appraisal bias also persists in Philadelphia, as we’ve demonstrated in our own analyses using the Federal Housing Finance Agency’s uniform appraisal dataset, or UAD.

The UAD is the only neighborhood-level source of information on home appraisal activity. However, the dataset reports less than half of census tracts in Philadelphia because the FHFA often suppresses data due to privacy concerns. In tracts with few transactions, reporting the data could identify individual homeowners.

Earlier this year, we employed a different approach using 2021-24 lending data from the Home Mortgage Disclosure Act. HMDA is an annually released federal database containing detailed information on most mortgage applications in the U.S. The data includes race, mortgage characteristics, property value, location and other details.

We wanted to understand whether there was a pattern of denied applications for cash-out refinance mortgages where the lender’s single reason for denial was collateral, which is generally established by the appraisal. Cash-out refinance mortgages are loans that pay off the homeowner’s existing loan and allow that homeowner to additionally borrow some of the equity they have in their home.

Our study shows that it was substantially more frequent that collateral was the single reason for that denial in nonwhite neighborhoods and for nonwhite homeowners.

This was the case whether the homeowner was seeking a conventional mortgage or a mortgage insured by the Federal Housing Administration. FHA borrowers frequently have lower credit or a lower down payment than a conventional borrower and pay an insurance fee that compensates for the higher risk they represent.

These two Philadelphia-based studies used different methodologies to arrive at the same conclusion, which we shared in a September 2025 report for the nonprofit Reinvestment Fund, where one of us is a senior adviser. That conclusion is this: Whether you want to buy a home or access the stored wealth in the home you already own in Philadelphia, you are disadvantaged in the valuing of the real estate if you are a person of color or if the home is located in a mostly Black or Hispanic neighborhood.

Possible solutions

Remedies are available, but in the current political climate the burden is increasingly on local governments, nonprofit advocacy groups and industry actors rather than the federal government.

More transparency: The home appraisal industry is opaque. While the uniform appraisal dataset provides some insight into appraisal bias, much of its data is not public. Further, the U.S. Department of Housing and Urban Development has not included neighborhood-level appraisal data for Federal Housing Administration transactions.

A national database of appraisals, similar to the HMDA database for loan applications, would improve transparency and accountability. While the HMDA did not eliminate lending discrimination, it is a valuable tool to uncover and address discrimination.

Get informed: A fair appraisal ensures that homeowners have an independent, accurate, expert opinion of the value of their home. But homeowners must understand how that opinion was derived and how they can contest that opinion of value when appropriate. Some lenders now allow an owner to get a second opinion if the owner feels the appraised value is inaccurate.

Raise public awareness: Local officials can inform the public about the nuts and bolts of appraisals and outline what can be done when bias occurs. Philadelphia is taking steps. The city’s Home Appraisal Bias Program is working to increase diversity of local appraisers, enhance appraisal transparency and educate consumers.

File a complaint: HUD has substantially pulled back from combating appraisal bias, including disbanding the Biden-era PAVE Task Force, which was making progress on the issue. The Trump administration has further impaired enforcement of the Fair Housing Act through layoffs and the withdrawal of critical policies long found to be effective in fighting housing discrimination.

Nevertheless, those who believe they have been subjected to appraisal bias can file complaints with HUD or their state or local fair housing agencies. This will at least create a record of the frequency of the issue.

Given the reduced role of the federal government today, there is an extra burden on state and local civil rights agencies and nonprofits to ensure alleged violations are investigated and, when appropriate, prosecuted.

What’s a ‘black box’ warning? A pharmacologist explains how these labels protect patients

Source: The Conversation – USA (3) – By C. Michael White, Distinguished Professor of Pharmacy Practice, University of Connecticut

Black box warnings can influence whether or not clinicians decide to prescribe a drug. SDI Productions/E+ via Getty Images

A “black box” warning on a health product sounds pretty scary – maybe even more so when it’s suddenly being taken off the packaging.

Americans were reminded of this type of public health messaging on Nov. 10, 2025, when the Food and Drug Administration announced it is removing the “black box” warning from hormone replacement therapy for menopause.

But what are these warnings, anyway? What’s their history, and how do they affect a drug’s use?

I am a clinical pharmacologist and pharmacist studying drug prescribing, safety and effectiveness for over 25 years.

Black box warnings – or as the FDA officially calls them, boxed warnings – are a tool for alerting pharmacists and clinicians that the medication may have serious risks. These health care professionals are then expected to communicate those risks to consumers.

An official source of drug information

Black box warnings for particular medications appear on the product package inserts that the FDA requires pharmaceutical companies to create for each prescription drug.

Product package inserts provide official information about the drug to health care professionals. These pamphlets are attached to bulk containers of drugs purchased by pharmacies so that the pharmacist has the most updated official information on the product. The package inserts are also published in textbooks such as the Physician’s Desk Reference and on websites maintained by drug manufacturers.

The requirement for product package inserts came out of a consumer protection law passed in 1966, called the Fair Packaging and Labeling Act, which aimed to prevent unfair or deceptive packaging in products used by consumers.

The package insert carries a set of official information about the drug, provided by the manufacturer and regulated by the FDA. The insert must include who the drug is approved for, proper dosing and administration, and a description of the key clinical trial results that showed it was effective and safe.

It must also disclose any health risks that the drug poses – such as a boxed warning.

Flagging safety risks

The FDA has two categories for the health risks that medications could pose: precautions and warnings. Both are listed on the package insert.

Precautions warn clinicians of possible harm that could result in minor or moderate injury to patients. Warnings, on the other hand, alert them to the potential risk of dangerous adverse events that could result in serious injury or death. The most serious warnings for a drug are called boxed warnings. The text of those warnings is enclosed by a black box on the insert so they will not be missed by clinicians.

According to a 2022 study, more than 400 medications currently carry black box warnings.

The FDA announced it was removing the black box warning from hormone therapy for menopause.

Antidepressants are one example. While such drugs can lessen the severity of depression symptoms, researchers have found that during the first few weeks of taking them, patients have an increased risk of suicide – particularly children and young adults. The FDA first issued a black box warning about the drugs’ use in children and adolescents in 2004 and expanded the warning to young adults in 2007.

Another example is clozapine, a drug used to suppress delusions experienced by people with schizophrenia. Although the drug is very effective, the FDA first gave it a black box warning when it was reintroduced to the market in 1989 because it can stop the production of white blood cells, potentially leading to life-threatening infections.

Hormone replacement therapy for menopause got its black box warning in 2003 after a clinical trial called the Women’s Health Initiative pointed to an increased risk of breast cancer without a reduced risk of heart disease in women who used it.

In subsequent years, reanalyses of the Women’s Health Initiative results, as well as data from other studies, have shown that the therapy is safe in women ages 50 to 60. Newer, safer formulations of estrogen and progestin have also emerged. These factors prompted the FDA to remove the warnings in November 2025, saying the therapy doesn’t pose significant risks.

Medical and legal realities

Black box warnings can influence clinicians’ choice of whether or not to prescribe a particular drug. For example, since other drugs for schizophrenia do not carry the serious risks that clozapine does, clinicians usually reserve that medicine for people who could not use those other drugs.

The black box warnings can also play a role in malpractice cases. In some states, package inserts and any warnings they contain can be used to establish a standard of care, leaving clinicians who deviate from them liable for damages. In other states, the warnings they list can be used to support findings of negligence.

For instance, the black box warning on the insert of the drug thalidomide states it can cause birth defects. It instructs clinicians to obtain a
a negative pregnancy test before use and ensure the patient is not able to get pregnant or is taking precautions to avoid pregnancy before prescribing. Failure to do so could make the clinician liable if the person taking the drug bears a child with birth defects.

Product package inserts are living documents. As new information becomes available, the FDA may find a medication’s risk is untenable and request the drug be removed from the market. Or it may decide to remove the boxed warning from the drug if new data shows the drug is less dangerous than previously thought.

Why Africa’s mineral-rich countries are not reaping the rewards of their wealth

Source: The Conversation – Canada – By Bonnie Campbell, Professeure émérite en économie politique. Département de science politique de l’Université du Québec à Montréal., Université du Québec à Montréal (UQAM)

Gold mining operations recently restarted at the Loulo-Gounkoto complex in western Mali after being shut down for several months. In January, the Malian government started blocking exports from the mine owned by Canada-based Barrick Mining (formerly called Barrick Gold).

The government blocked exports and took control of three tonnes of bullion following a dispute with Barrick Mining over alleged unpaid taxes.

This particular case is too complex to be discussed here. But disputes over revenue distribution raise important questions about how mineral-rich countries can benefit from their natural resources.

According to the International Monetary Fund, tax avoidance by multinational mining companies costs African countries between US$470 million and US$730 million per year in tax income.

Generating government revenue through natural resource taxation is critically important for sub-Saharan African countries seeking to improve infrastructure, health services and meet social development goals.

A variety of reasons explain why mineral-rich countries in sub-Saharan Africa are not profiting appropriately from their mineral wealth.

Power imbalances, unfavourable revenues

The Intergovernmental Forum on Mining and the Organisation for Economic Co-operation and Development have identified different obstacles to mining revenue collection including faulty legislation, abusive transfer pricing and other artificial profit-shifting.

In addition, fiscal incentives commonly provided to attract mining investment, such as significantly lowering tax and royalty rates, rarely prove to be worth the loss in government revenue.

These excessive concessions to foreign mining companies have led to widespread discontent, poverty and underdevelopment in Africa, despite abundant mineral wealth. This situation has been condemned by leaders across the continent.

In response, the African Union’s African Mining Vision and the policies it has inspired, notably the reform of mining codes, are attempts to ensure a more lasting contribution of the continent’s mineral resources.

Yet the power imbalances between foreign companies and African governments remain very much in place and shape negotiations around mining codes, contracts and practices.

While situations vary from country to country, sector to sector and site to site, research has sought to identify key obstacles to increased State mining revenue.

The unequal influence in negotiations that favours mining companies leads to numerous irregularities. Examples include prolonging stability clauses despite regulatory reforms and prioritizing mining contracts over broader national regulatory frameworks.

At the international level, African states are hindered from implementing policies that benefit local communities due to international trade regime practices, tariff import privileges and bilateral conventions that act as powerful deterrents.

Mali’s mining code

In Mali, the mining sector is a key part of the economy. In 2022, the sector contributed 9.2 per cent of GDP, 76.5 per cent of export revenue and 34.8 per cent of state revenue.

As is the case elsewhere on the continent, new Malian mining legislation aims to help rectify the legacy of environmental damage and disappointing mining revenue. Mali’s 2023 mining code reflects reforms to improve national benefits from the sector similar to measures in Tanzania, Zambia and the Democratic Republic of Congo.

Such reforms included increased state ownership requirements (typically 10-30 per cent), higher royalty and tax rates, local content and employment requirements, greater environmental and social responsibility provisions and enhanced community development obligations.

The 2023 code aims to strengthen Mali’s sovereignty over its resources and bring about a more equitable distribution of the benefits.

The fiscal regime has been reformed so that, among other measures, certain tax exemptions that mining companies received were abolished. Similarly, the new code puts an end to the fiscal concession of 25 per cent for a period of 15 years permitted by former codes. The new code introduces a royalty on production of 10 per cent for that exceeding the quantity projected.

In addition, several funds were created to respond to the needs of the sector and favour social inclusion.

Another important innovation is the law concerning local content in the mining sector. This law aims to encourage the participation of national enterprises and workers in the mining sector.

As occurs in other mineral-rich countries, Mali has faced strong pushback, particularly from the largest and most powerful companies. This has led to an escalation of conflict rather than negotiated solutions.

Significantly, several companies have reached agreements with the Malian government, such as Robex Resources. The U.K.-based Endeavour Mining has negotiated terms with the government to operate under the new mining code.

Two additional gold producers have also signed agreements to operate under the new mining code: Faboula Gold and Bagama Mining.

These projects, while less capital-intensive than others, illustrate the possibility of successful initiatives under the new code. They also provide important employment opportunities in rural areas.

Greater resource sovereignty

Some industry analysts have criticized mineral-rich countries for adopting a “resource nationalism” approach. However, research shows that well-managed, transparent and stable mining revenue in Mali and Senegal could help improve access to health care and social services.

Exercising greater sovereignty over natural resources to ensure the well-being of a country’s population might better be commended as responsible resource nationalism.

There are serious military and security threats facing Mali and its neighbours. By providing revenue and employment, the mining industry can play a key role in addressing these insecurities.

This role involves respecting national regulations and paying a fair share of tax revenue. Ultimately, the industry’s profitability is very much tied to the social stability of the country and the health, social and economic welfare of its people.

The path to responsible mining in northern Ontario starts with Indigenous consent

Source: The Conversation – Canada – By Tamara Krawchenko, Associate Professor, School of Public Administration, University of Victoria

Canada and Ontario are accelerating efforts to attract global investment and speed up approvals for new mining projects.

Ontario’s government has introduced new policies aimed at attracting investors and accelerate project timelines. Central to this strategy are laws like Bill 5, the Protect Ontario by Unleashing our Economy Act, and Bill 71, the Building More Mines Act.

The surge in global demand for “critical minerals” such as nickel, lithium and cobalt — essential inputs for electric vehicles and clean energy technologies — has positioned mining as a cornerstone of energy transition strategies. Northern Ontario, endowed with vast mineral resources, has become a focal point in Canada’s emerging green economy.

Yet this potential is shadowed by the legacy of “sacrifice zones” — regions where the environmental and social costs of mining have fallen heavily on Anishinaabe, Cree and Oji-Cree Nations and communities, while most benefits have accrued elsewhere.

How governments advance Indigenous inclusion, share prosperity with First Nations and create greater project certainty will depend on principles of respectful partnership, shared rewards and risks and long-term stewardship.

Environmental and Indigenous rights concerns

Canada’s accelerated approach to mining raises major concerns for both the environment and Indigenous rights.

The Hudson Bay Lowlands, for example, are one of the world’s largest carbon sinks and disturbances there could release vast amounts of greenhouse gases. Building mines, roads and energy lines in these sensitive ecosystems threatens biodiversity, water systems and the traditional livelihoods of First Nations communities.

Ontario’s digitized “claim-staking” system allows companies to register mining claims instantly without prior consultation. In some cases, exploration occurs on lands still under legal negotiation or where Indigenous title is unresolved.

Many First Nations have voiced frustration that the current consultation process is too brief and procedural to meet constitutional or treaty obligations.

The Chiefs of Ontario have called for a pause on new mining claims and deeper reforms to ensure that any future developments align with Indigenous consent.

A rights-based approach to mining

A recent OECD report outlines both the opportunities and challenges that rising mineral demand brings to First Nations and local communities in Northern Ontario. The report also lays out a practical road map for a more sustainable mining sector.

As contributing authors, we accompanied the OECD process of extensive interviews and roundtables with First Nations leaders, mining companies, policymakers and community organizations across the region.

We sought to understand on-the-ground realities and to identify ways to align economic development with Indigenous rights and community well-being.

From the recommendations of the report, we interpret three key actions for a rights-based territorial development approach that promotes responsible mining while upholding Indigenous rights.

3 key actions

1. Investing in communities

Many First Nations need major investments in water, housing, infrastructure, health and social supports to meet basic human rights. Without addressing these foundational needs, asymmetrical development will only deepen inequalities between national interests and wealth creation. It is very hard to think about mining development when basic needs are not being met.

2. Gaining Indigenous consent

Following the lead of British Columbia and the Northwest Territories in legally committing to implement UNDRIP (the United Nations Declaration on the Rights of Indigenous Peoples), Ontario should build on existing efforts to provide a formal mechanism for guiding companies towards securing free, prior and informed consent and align provincial legislation with UNDRIP.

Indigenous rights-holders must be properly informed, meaningfully consulted and give their consent before any projects go forward. This consent should apply throughout the entire project life cycle, from exploration and feasibility studies to mine closure and land restoration.

This should also pertain to “brownfield” sites (existing mines) and patented lands, some of which are currently exempt from consultation under Ontario’s Mining Act. While major changes to a mine site that could negatively affect Indigenous rights will trigger the duty to consult, smaller changes may not and this is decided on a case-by-case basis. This can create grey areas and a lack of legal levers for communities to renegotiate when amendments are made to mining projects.

3. Capital, equity ownership and royalty frameworks

To move beyond one-time compensation agreements, some First Nations may be interested in securing equity stakes in mining ventures, sharing both risks and rewards through access to capital.

When First Nations participate as co-investors, it signifies that the project has undergone a free, prior and informed consent processes, meaning potential legal, reputational and social risks — including community opposition or court challenges — are significantly minimized.

Indigenous co-investment typically requires the establishment of strong governance mechanisms, including clear arrangements for shared decision-making, benefit sharing, formal agreement-creation and high environmental and social standards, all of which enhance a project’s reputation for responsible operation.

Direct resource revenue-sharing agreements are another option. The Ontario government has already signed such agreements with some First Nations and Tribal Councils. This ensures equity among participating First Nations.

Building a stronger, more prosperous Ontario

The future of mining in northern Ontario sits at a crossroads. Governments want to move quickly to capitalize on mineral demand, but unless this growth is tied to consent (real engagement), equity and stewardship, it risks reproducing past injustices. This is unacceptable risk to all parties.

True prosperity means development that upholds the rights of First Nations, protects their ecosystems and ensures communities share in the benefits.

If implemented, these priorities — consent, ownership and stewardship — could transform the region from a site of resource extraction into a model of partnership and resilience. It means a different kind of mining anchored in respect and sustainability.

Pill-induced oesophagitis: why your medication could be damaging your throat – and what to do about it

Source: The Conversation – UK – By Adam Taylor, Professor of Anatomy, Lancaster University

Every year, people around the world take an astonishing 3.8 trillion doses of medicine. Most of these medicines are swallowed rather than injected or inhaled, because the oral route is the easiest, safest and most familiar way to take a drug at home. But even something as routine as swallowing a pill can sometimes cause harm.

Pill-induced oesophagitis occurs when a tablet or capsule gets stuck in the narrowing at the lower end of the oesophagus, where it meets the stomach. If a pill lodges there and begins to dissolve, it can release its active ingredients directly onto the delicate tissue. These substances are often acidic or alkaline, and that chemical burn can quickly cause pain and inflammation. Although considered uncommon, studies suggest it has an estimated incidence of 3.9 per 100,000 population per year. It may be under-reported because mild cases often resolve without medical attention.

The inner surface of the oesophagus is lined with a thin, specialised mucosal layer that helps food pass smoothly into the stomach. By contrast, the stomach’s mucosa produces mucus to protect against acid, which is essential for digesting food and destroying microbes. When a pill dissolves too early, it exposes the unprotected oesophageal lining to caustic substances that it was never designed to handle, leading to irritation, inflammation and sometimes ulceration.

Symptoms can mimic heartburn or indigestion but are usually sharper and more localised, with pain felt behind the breastbone. Some people experience pain when swallowing, or a sudden hoarseness or change in voice. In rare and untreated cases, the damage can deepen, allowing ulcers to rupture through the oesophageal wall, leading to severe infection or even death.

Middle-aged women are most often affected, partly because they are statistically more likely to take regular medication, including treatments for bone health. Older adults are also at increased risk because age-related changes in oesophageal motility make it harder for pills to pass smoothly into the stomach. People with conditions that alter the shape or position of nearby organs — such as an enlarged heart or thyroid—may also be at higher risk.

Children are less commonly affected, but they have their own unique risk factors. Difficulty swallowing pills, smaller anatomy and inexperience can all increase the likelihood of a tablet becoming lodged.

Medications most likely to cause damage

Several well-known medicines can irritate or injure the oesophagus if they linger there. Bisphosphonates, used to treat osteoporosis, are a leading cause, and this may explain why women are more commonly affected. Around one in ten post-menopausal women in the UK are prescribed oral bisphosphonates.

Tetracycline antibiotics, used for a wide range of infections, carry similar risks. Aspirin and ibuprofen, two widely used non-steroidal anti-inflammatory drugs, can also induce oesophagitis, though they work differently by disrupting the protective barrier rather than causing a direct chemical burn.

Even over-the-counter so-called natural products, such as dietary supplements and vitamins, can cause problems. Caffeine tablets, potassium chloride supplements, L-arginine and high-dose vitamin C or vitamin E pills have all been linked to pill-induced oesophagitis.

Caffeine, in particular, can damage the gastrointestinal lining even without becoming stuck. Concentrated doses stimulate acid production and increase gut motility, which can weaken the protective mucosal barrier and lead to inflammation.

Potassium chloride is a mineral supplement that replaces potassium lost through illness or medication, but its large, dense tablets can physically irritate the oesophagus if they dissolve before reaching the stomach. L-arginine, an amino acid supplement, and vitamin C are chemically alkaline and acidic respectively, so both can burn or inflame the lining if trapped. Vitamin E, often packaged in smooth gel capsules, can also linger and leak irritating oils.

Gelatine-based soft capsules carry their own risk. Because gelatine is hygroscopic, meaning it absorbs moisture from its surroundings, it can soften and become sticky. This increases the chance that a capsule will cling to the oesophageal wall rather than pass smoothly into the stomach. When that happens, the capsule’s contents may be released directly onto sensitive tissue, causing local irritation or ulceration.

Prevention and treatment

The good news is that most mild cases resolve within a few days or weeks once the offending medication is stopped. Short courses of antibiotics, for instance, rarely cause lasting harm.

There are, however, simple steps to prevent oesophagitis from developing in the first place. Always take pills with a full glass of water – about 200 ml – to ensure they reach the stomach. Take them on an empty stomach if advised, and remain upright for at least 30 minutes afterward. This helps prevent regurgitation and gives the medication time to dilute in the stomach.

For drugs like bisphosphonates, your doctor may recommend switching to a different formulation or a non-oral route such as injections, which are more potent but can bring other side effects. If long-term treatment is necessary, additional medications may help protect the digestive tract. Proton pump inhibitors reduce stomach acid and support healing, while sucralfate forms a soothing barrier over irritated tissue.

If you take several medications that can cause oesophagitis, swallow them one at a time, and consider using a pill cutter to make larger tablets smaller. Above all, monitor any new or worsening symptoms, and seek medical advice promptly if you notice persistent pain or difficulty swallowing.

Pill-induced oesophagitis is a painful but preventable condition. Simple habits like drinking plenty of water, sitting upright and following medication instructions carefully can dramatically reduce the risk. If swallowing pills is difficult or discomfort develops, speak to a healthcare professional about alternatives. Sometimes the smallest change, like how you take a tablet, can make all the difference to your health.

How soil could help us reach climate targets

Source: The Conversation – UK – By Jess Davies, Chair Professor in Sustainability, Lancaster University

The UN climate summit, Cop30, is currently taking place in Belém, Brazil, a region with some of the most carbon-dense soils on Earth: the Amazonian dark earths. These deep, dark and exceptionally fertile soils are thought to have been intentionally enriched with carbon.

Ancient Indigenous communities likely spread ash and organic waste on the land to enhance fertility and support crop production. Now, some conservation groups like Conscious Planet are calling for countries to commit to intentionally enhancing soil carbon the world over as a key part of international climate action. As a soil carbon scientist, I’m here to explain why.

Soil is a vital component of the climate system. It is one of the largest stores of organic carbon on Earth – containing more carbon than both the atmosphere and vegetation combined. This makes soil both a climate risk and an opportunity.

While soils may not look that dynamic, they are constantly changing as they exchange carbon with the atmosphere and the plants and organisms living within them. As plants grow, their roots release organic compounds, adding carbon into the soils and exchanging it with other organisms like fungi. As plants and other organisms die, they add their organic matter to the soil, and decomposition of this material by microorganisms leads to the release of some of it as carbon dioxide and methane.

Declining soil health is a global concern – here’s how AI could help


In natural conditions, these in and out flows may be well balanced, but human actions, such as deforestation and agriculture have disturbed these cycles, leading to the release of carbon dioxide and other greenhouse gases. It is estimated that past land use change and soil degradation is responsible for about 15% of the global warming caused by greenhouse gases. However, reversing this trend can increase the amount of carbon stored in soils, helping to mitigate climate change.

The slow rise of soil in climate policy

Soil first gained attention on the UN climate summit stage in 2015, when France launched the 4 per 1000 initiative during Cop21 in Paris. The idea: if global agricultural soils increased their carbon stocks by just 0.4% per year, it could offset nearly all annual greenhouse gas emissions.

While questions were subsequently raised about the feasibility of this rate of carbon gain, the target was intended as an aspirational one and the initiative has been important in putting soils on the climate and agricultural agendas. Also, putting carbon back into agricultural soils is not only about climate mitigation. Increasing the amount of organic matter, and in turn organic carbon, stored in soils means improving water holding capacity and nutrient cycling, helping to increase the sustainability and resilience of crop production and global food security.

The 4 per 1000 initiative has had good buy-in: 41 nations have signed up as members, along with hundreds of other regions, environmental charities, research institutions and businesses. At subsequent UN climate summits, focus on soils has grown, with soil featured more heavily in land use and climate finance initiatives.

Yet in most national climate pledges, soil still appears only indirectly according to a new global analysis, with vague references to “soil health” embedded in other sectors like agriculture or adaptation, rather than as a clear mitigation strategy with explicit carbon targets.

An expert explains the meaning of nationally determined contributions or NDCs.

This gap matters because those pledges (known as nationally determined contributions) drive government actions. If soil carbon targets are not explicitly named, they probably won’t be funded or prioritised.

My group’s research has shown how important soils could be to national climate action – even for high-emitting countries with relatively little land per capita, such as the UK. Our modelling work suggested that reasonable levels of afforestation and grassland restoration could deliver up to 7% of the cuts in emissions needed by 2050 in the UK. This would be a substantial contribution, and other soil-focused actions, like the peatland restoration would deliver further emissions savings.

Concrete commitments

Cop30 in Brazil – a global hotspot for both nature and agriculture – provides an excellent opportunity to ensure soils feature strongly in pledges and implementation plans.

Pledges to invest in nature will feature highly. For example, the Tropical Forests Forever Facility is a new global fund supporting tropical forest conservation. It’s important that soils are robustly considered as part of this.

While soil is a potentially powerful ally for climate mitigation and adaptation, nothing can replace rapid cuts to fossil fuel emissions. In a warming world, rising temperatures and extreme weather threaten the very ecosystems that store carbon. Our research suggests that soils can only remain a net carbon sink under optimistic climate scenarios.

Put simply, stronger and more specific soil carbon targets could help us on the road to better climate outcomes, but only if we act fast to protect soils and other carbon rich ecosystems, while cutting emissions across our economies.
