Deadpan is not so much a type of joke as a mode of delivery, a manner of address to an audience that often provokes nervous laughter.

Comedian Nathan Fielder’s persona is marked by deadpan. In his hit HBO comedy series “The Rehearsal,” he maintains a blank facial expression as he listens to contestants fumble their auditions for “Wings of Voice,” his fake reality singing competition. He takes the task of donning the guise of an adult-size infant very seriously, in order to relive the childhood of heroic pilot Sully Sullenberger. His voice is steady and monotone as he converses with a male pilot who cluelessly describes the egregious behavior he’s displayed toward women colleagues.

What makes deadpan feel so off, so destabilizing, so dryly funny?

One reason is that performers – particularly comedians – are expected to be expressive and over the top, or even hint to the audience that they’re supposed to chuckle, similar to a sitcom laugh track.

As I recently organized an exhibition on photography’s relationship to humor, I found myself thinking about how deadpan works in photography. A still, deadpan image might seem like a paradox: Don’t you need a real, live performance? But exploring how photographers have deployed deadpan sheds light on just how powerful and incisive this form of humor can be.

Are you not entertained?

“Pan” was slang for “face” in the 19th century. The genre of deadpan humor was popularized in movies by actor Buster Keaton, whose expressionless, blunt and stilted presence before the camera inspired his nickname, “the Great Stone Face.”

Sprung upon an audience, deadpan can yield a reaction that reveals what philosopher Ted Cohen has described as the “conditional” nature of humor – that it plays into assumptions, expectations and prior knowledge precisely to disrupt them.

Puzzled by the unmet promise of a clear emotion or narrative, the audience laughs uncomfortably at their own bewilderment. The performer’s restraint registers as absurd.

The opposite of postcard perfect

As a medium, photography has historically been burdened by debates over its ability to convey ideas or expression. To early critics, a photograph seemed “mechanical” because it appeared only to reproduce the world, rather than express something new. Compared to drawing or painting, they reasoned, the camera could merely copy.

But I would argue that for these very reasons, photography is a rich lens to explore how deadpan works visually. In photography, deadpan doesn’t even need to involve people.

Take the work of Californian photographer Henry Wessel Jr. Known for his decades-long documentation of everyday life in California, Wessel was one of 10 photographers featured in the watershed 1975 exhibition “New Topographics” at the George Eastman Museum in Rochester, New York, which trained a lens on landscapes altered by humans rather than nature alone – think gas stations, parking lots and tract homes instead of national parks.

Yet the shift Wessel and the other photographers initiated did not simply concern subject matter, but the manner in which they presented it: coolly, at least by the standards of iconic landscape. Previously, photographers such as Ansel Adams had infused their pictures with drama and contrast to provoke the same reverence that they felt toward nature’s beauty. Museumgoers were accustomed to seeing these kinds of landscapes: picturesque and sublime, featuring sprawling mountain ranges and billowing clouds rendered in dramatic tonal ranges.

By contrast, Wessel photographed suburbia in the American West – and with irreverent affection. He composed his images with mock casualness and printed in a narrow tonal range, as if yielding to the leveling quality of the bright sunlight on the stucco and concrete.

This was puzzling; Wessel’s pictures seemed worlds away from fine art landscape photography. They resisted awe and transcendence in favor of dry bemusement. By 1970s standards, his subject matter and aesthetic were equivalents of deadpan’s monotone. Who in their right mind would make the effort to take such a plain picture of a humdrum house?

Yet by adopting this style, Wessel encouraged audiences to pay greater attention to their immediate surroundings: to read front porches, carports and landscaping as evidence of people’s lifestyles and values. His photographs demonstrate the wealth of information that lurks in the mundane.

To Wessel, the seemingly mundane was brimming with intrigue.

Why so serious?

Other photographers have marshaled deadpan to explore themes of identity and belonging.

Tseng Kwong Chi was a prominent personality in the East Village art scene in the 1980s and a friend of pop artist Keith Haring. In his landmark series of proto-selfies, “East Meets West,” the Hong Kong-born artist used a funny personal experience as the point of departure.

Dining at Windows on the World, the restaurant atop the North Tower of the World Trade Center, Tseng decided to wear a Zhongshan suit, or “Mao suit,” as it was known in the West, due to its association with the former Chinese leader Mao Zedong.

The restaurant’s staff treated him as a dignitary, inspiring Tseng to embark upon what ultimately became over 100 self-portraits in which he appeared in this guise of an “ambiguous ambassador.” In the series, Tseng appears in front of popular tourist destinations – Disneyland, Mount Rushmore, Cape Canaveral, Paramount Studios – but never cracks a smile. Goofy hams it up for the camera as Tseng’s suit and serious expression subvert the conventions of tourist snapshots.

In doing so, “East Meets West” deploys deadpan to tell a broader story about the search for belonging as an immigrant and a queer person of color.

Similarly, in his series “Entering Zig’s Indian Reservation,” Zig Jackson adopts a caricature-like persona to both mock and resist Native American stereotypes.

Jackson was the first member of his family to leave their reservation in North Dakota. He spent time in various western states before enrolling as a photography student at the San Francisco Art Institute in the early 1990s.

Early in his time there, as he went for a jog in the city’s sprawling Golden Gate Park, he heard grunting bison from the nearby paddock, a beloved San Francisco landmark since 1892. Jackson felt simultaneously at home and homesick, like he was “among relatives.”

Wearing a war bonnet, or feathered headdress – an item of regalia that is often appropriated by white people “playing Indian” – he returned to the site to “claim the buffalo as my own,” as he explained to me in an email.

In the image, Jackson meets the camera with an expressionless gaze, sitting next to a sign he made to mark his fictive reservation. This and other works from this series are deadpan: Jackson’s headdress registers as jarring with his street clothes, and the rules spelled out on the sign – including “NO PICTURE TAKING” and “NEW AGERS PROHIBITED” – read as tongue in cheek. But the photographs are also melancholy visualizations of feeling out of place.

The matter with fact

Sometimes I find myself wondering whether photography itself is inherently deadpan. It possesses a built-in bluntness that registers as absurd or confusing in certain contexts.

For her series “Skirts,” British conceptual artist Clare Strand rented banquet tables from a commercial catering company, covered them with linens and photographed them one by one. She then presented the images as a grid, as if they were specimens.

The viewer might initially assume that there is some sort of overarching narrative: Are they for a party? An award ceremony?

But Strand provides no answers. All dressed up with nowhere to go, the tables show that to photograph something is to transform it: In anointing an object, person or scene as worthy of being singled out, the photographer confers importance on it. From there, the viewer is left to fill in the blanks.

Scholar Heather Diack has argued that conceptual artists have subverted photography’s purported straightforwardness by making photographs that don’t simply copy or “capture” reality. Their work shows how photographs are anything but natural, literal or transparent.

Yet because people tend to associate photography with objectivity, it renders the medium ripe for deadpan humor – for crafting the appearance of a “straight face,” but with a wink.

Misunderstood Malthus: The English thinker whose name is synonymous with doom and gloom has lessons for today

Source: The Conversation – USA (3) – By Roy Scranton, Associate Professor of English, University of Notre Dame

A portrait of Thomas Malthus by John Linnell. Wellcome Collection via Wikimedia Commons, CC BY

No one uses “Malthusian” as a compliment. Since 1798, when the economist and cleric Thomas Malthus first published “An Essay on the Principles of Population,” the “Malthusian” position – the idea that humans are subject to natural limits – has been vilified and scorned. Today, the term is lobbed at anyone who dares question the optimism of infinite progress.

Unfortunately, almost everything most people think they know about Malthus is wrong.

The story goes like this: Once upon a time, an English country parson came up with the idea that population increases at a “geometrical” rate, while food production increases at an “arithmetical” rate. That is, population doubles every 25 years, while crop yields increase much more slowly. Over time, such divergence must lead to catastrophe.

But Malthus identified two factors that reduced reproduction and held off disaster: moral codes, or what he called “preventative checks,” and “positive checks,” such as extreme poverty, pollution, war, disease and misogyny. In the all-too-common caricature, Malthus was a narrow-minded clergyman who was bad at math and thought the only solution to hunger was to keep poor people poor so they had fewer babies.

Understanding Malthus in a broader context reveals a very different character. As I discuss in my 2025 book “Impasse: Climate Change and the Limits of Progress,” Malthus was an innovative and insightful thinker. Not only was he one of the founding figures of environmental economics, but he also turned out to be a prophetic critic of the belief that history tends toward human improvement, which we call progress.

God and science

On the topic of progress, Malthus knew what he was talking about.

He was raised and educated by dissenters: progressivist English Protestants who advocated the separation of church and state. He was taught by the radical abolitionist Gilbert Wakefield, and his father was a friend and admirer of the Enlightenment philosopher Jean-Jacques Rousseau, whose ideas helped inspire the French Revolution.

Despite struggling with a cleft palate, Malthus distinguished himself at Cambridge, where he studied applied math, history and geography. Going into the clergy was a common choice for educated young men of middling means, and Malthus was able to secure a parsonage in Wotton, Surrey. But that didn’t mean giving up his interest in social science.

An Essay on the Principle of Population” was shaped by Malthus’ theological views, but it is also a deeply empirical work and became more so as he revised it in later editions. His argument about geometrical and arithmetical growth rates, for instance, was based on the rapid population growth witnessed in the American Colonies.

It was also based on what he saw happening around him in Britain. Over the final decades of the 18th century, Britain was wracked by repeated food shortages and riots. The population rose from 5.9 million to 8.7 million, an increase of almost 50%, while agricultural production lagged. In 1795, hungry Londoners mobbed King George III’s coach demanding bread.

Boundless optimism

But why was Malthus talking about population in the first place? As Malthus himself explains, his essay was inspired by an argument with a friend about the journalist and novelist William Godwin – best known today as the father of Mary Shelley, author of “Frankenstein.”

Malthus and Godwin had similar backgrounds. Both came from dissenting middle-class families, were educated in progressive schools and began their careers as ministers. But Godwin’s extreme radicalism put him at odds even with his fellow dissenters, and he soon left the pulpit to take up the pen.

The book that made Godwin’s name and provoked Malthus was “An Enquiry Concerning Political Justice,” published in 1793. Today, it is considered a founding text of philosophical anarchism. Originally, however, Godwin’s “Enquiry” was seen as a thunderous articulation of Enlightenment progressivism.

Godwin argued that all social problems could be eliminated by reason’s proper application. He advocated abolishing marriage, redistributing property and eliminating government. What’s more, he asserted that progress led inevitably to a utopian world, where humans will no longer have to reproduce because we’ll be immortal:

“There will be no war, no crimes, no administration of justice as it is called, and no government. … But beside this, there will be no disease, no anguish, no melancholy and no resentment. Every man will seek with ineffable ardour the good of all.”

Such things would come about in due time, Godwin assured his readers, solely through the spread of rational discussion.

From his poverty-stricken parsonage in Wotton, Malthus saw things differently. Historian Robert Mayhew describes Wotton at the time as an industrial wasteland afflicted by “agrarian poverty … high birth rates and short life spans.” Studying history led Malthus to conclude that societies moved not in an ever-ascending line of progress but in cycles of expansion and decline. Godwin’s utopian story didn’t seem to match the evidence.

Reform – within reason

Malthus aimed to puncture Godwin’s grandiloquent progressivism. But he wasn’t saying positive change was impossible, only that it was limited by the laws of nature.

“An Essay on the Principles of Population” was his attempt to ascertain where some of those limits might lie, so that policy could respond to social problems effectively, rather than exacerbating them by trying to achieve the impossible. As a writer and active member of the Whig Party, Malthus was a reformer who advocated free national education, the extension of suffrage, the abolition of slavery and free medical care for the poor, among other programs.

Since then, science and industry have made incredible advances, leading to changes Malthus would have scarcely found credible. When his essay was published, the global human population was around 800 million. Today it is over 8 billion, a tenfold increase in little more than two centuries.

Over that time, proponents of progress have scorned the idea that humans are subject to natural limits and denigrated anyone who questioned the fantasy of infinite growth
as “Malthusian.” Yet Malthus remains important because his pessimistic account of society so clearly articulates an insight that refuses to be repressed: The laws of nature apply to human society.

Indeed, “the Great Acceleration” in human development and impact over the past 80 years may have pushed society to the breaking point. Scientists warn that we’ve exceeded six of the nine boundary conditions for sustainable human life on Earth and are close to exceeding a seventh.

One of those conditions is a stable climate. Global warming threatens to not only raise sea levels, increase wildfires and supercharge storms, but also amplify drought and disrupt global agriculture.

Malthus may not have foreseen the developments that fueled human growth over the past two centuries. But his fundamental insight into the limits of growth has only become more relevant. As we face accelerating global ecological crisis, it may be time to revisit the pessimistic idea that we live in a world with limits. Reconsidering what we mean by “Malthusian” might be a good place to start.

Trump’s Epstein problem is real: New poll shows many in his base disapprove of his handling of the files, and some supporters are having second thoughts about electing him

Has President Donald Trump survived the latest and most serious firestorm of controversy over the Epstein scandal? Or has the Trump administration’s handling of the release of information concerning the prosecution of Jeffrey Epstein, a convicted child sex trafficker and Trump’s former friend, hurt the president?

A number of journalists, pointing to recent public opinion polls, have claimed that the scandal has hurt Trump. Others have argued that the public has largely moved on and the Epstein controversy no longer presents a political liability for Trump.

But both of these conclusions are based on limited polling about the Epstein controversy and thus may be premature.

Our recent University of Massachusetts Amherst national poll includes particularly detailed questions about the Epstein controversy and attitudes toward Trump, and thus provides fresh insights on how the controversy has affected public support for Trump.

We find that Trump’s handling of the Epstein controversy has done significant damage to his standing, particularly among his core supporters.

Trump ‘fumbling the matter’

Americans are paying close attention to the prolonged Epstein controversy. Our polling finds that 3 in 4 respondents have heard, read or seen “a lot” or “some” about Epstein.

Moreover, most believe that Trump is fumbling the matter.

Seven in 10 Americans believe that Trump is handling the matter “not well.” This includes pluralities of Trump’s most loyal supporters, 43% of Republicans, 43% of conservatives, and 47% of those who voted for him in 2024.

When we drill down on the 47% of 2024 Trump voters who disapprove of Trump’s handling of the Epstein controversy, we find significant cracks in the MAGA facade. Among members of this group, 28% now disapprove of Trump as president.

When we take demographics, ideology, partisanship and assessments of the economy into account, disapproval of Trump’s handling of the release of the Epstein files is still associated with an increase in disapproval of Trump.

Voter regret

Even more significantly, we find that among 2024 Trump voters, negative views of Trump’s handling of the Epstein files are associated with an increased desire to make a different choice if the 2024 election could be rerun.

More specifically, among Trump voters who believe that the president has mishandled the release of the Epstein files, more than one quarter – 26% – indicate that they would not vote for Trump if they had the opportunity to vote again in the 2024 election.

While there are no election do-overs, it is clear that the Epstein scandal has hurt Trump among his base of voters.

Much can happen between now and the midterm elections in November 2026, of course.

But if Trump fails to satisfy his political base, perceptions among Trump voters that he has mishandled the controversy could reduce enthusiasm and participation in the elections. Even if the share of Republicans alienated by the Epstein controversy is relatively small, this could hurt Republicans in close contests.

With over a year to go, the facts on the ground will likely change. But as of today, the controversy over the release of the Epstein files remains relevant. Whether the president responds in a manner that satisfies his voters is a question that could have important political consequences.

A Detroit street is named in honor of Vincent Chin – his death mobilized Asian American activists nationwide

The legacy of Vincent Chin has recently been commemorated in a street sign bearing his name on the corner of Cass Avenue and Peterboro Street in Detroit’s historic Chinatown.

I was glad to see it. Watching the 1987 documentary “Who Killed Vincent Chin?” and learning about his life and Asian American activism changed my life.

I was 18 and taking my first Asian American studies class at the University of California, Santa Barbara. The film made me realize two things: Asian Americans are targets of racial violence, and Asian Americans across the ethnic spectrum could join together to fight for civil rights. This led to my passion for social justice.

I’m proud to now be a professor of Asian American studies and critical race theory who teaches my students about Vincent Chin.

So who was Chin, and why did his death catalyze an Asian American civil rights movement?

A fatal brawl

Chin, an Oak Park resident, was 27 years old on the night of his bachelor party, June 19, 1982. He got into a fight with two white men – Ronald Ebens, a Chrysler car plant supervisor, and Michael Nitz, an unemployed autoworker and Ebens’ stepson.

According to Racine Colwell, a dancer at the Fancy Pants Club in the Detroit area, Ebens shouted, “It’s because of you little motherf–kers that we’re out of work.” Detroit in the early 1980s was in an automotive slump. People blamed Japanese auto imports and the Japanese people, in general, for the economic downturn. The assailants didn’t seem to understand or care that Chin was actually Chinese.

After the fight between Chin and Nitz and Ebens, Chin and his friends ran out of the club. Ebens and Nitz ran after them, with Nitz grabbing a baseball bat from his car. When they found Chin outside a McDonald’s on Woodward Avenue, Nitz held Chin while Ebens beat his body and head with the bat. They were stopped by two off-duty police officers who had been inside the fast-food restaurant.

After the attack, Jimmy Choi, a member of the bachelor party, cradled Chin in his arms. He said that Chin’s last words were “It’s not fair.” Chin died four days later.

Ebens and Nitz were charged with second-degree murder, but their lawyers pleaded the charge down to manslaughter. At the end of the trial, Judge Charles Kaufman fined them US$3,000 each and sentenced each to three years’ probation, explaining: “These weren’t the kind of people you send to prison. … You don’t make the punishment fit the crime. You make the punishment fit the criminal.”

Asian Americans organize for legal justice

The sentencing enraged Chin’s friends, family and the greater Chinese and Asian American community of Detroit.

Activists of various Asian ethnicities and their non-Asian allies created American Citizens for Justice, an organization that pressured the Justice Department to investigate the violation of Chin’s civil rights and to see Ebens and Nitz imprisoned for Chin’s murder. Lily Chin, Vincent’s mother, was a key advocate in the pursuit of justice for her son, showing up to rallies and interviews to remind people of Vincent’s death for nearly a decade.

While there were other moments, such as the anti-eviction fight for the I-Hotel in San Francisco, that brought Asian Americans of all ethnicities together to fight for civil rights, Chin’s murder sparked a broad awareness. Asian Americans realized that what happened to Chin could happen to them.

American Citizens for Justice held press conferences and gained support from local African American activists in Michigan and national Black leaders like Jesse Jackson, whose presence helped bring more attention to the Chin tragedy.

Activists were successful in forcing the FBI to open an investigation. The resulting 1984 federal trial was the first time the Justice Department had argued that the civil rights of an Asian American person had been violated. Nitz was found not guilty on two counts. Ebens was found guilty and sentenced to 25 years in prison. However, a 1986 federal appeals court ruling overturned the conviction, freeing Ebens.

A civil suit filed against Ebens and Nitz on behalf of Lily Chin was settled out of court in 1987. Nitz agreed to pay $50,000 and Ebens $1.5 million – the projected income that Chin would have made had he lived.

Nitz fulfilled his debt, but Ebens made only a few payments. By 1987, Ebens had been unemployed for five years. He stopped making payments after he moved to Nevada. Estimates in 2016 place Ebens’ debt to the Chin estate at over $8 million, including accumulated interest.

Chin’s death had a profound impact on the criminal justice system in Michigan and nationally. Michigan made it harder to plead down murder charges to manslaughter and required prosecutors to be present at sentencings to face victims. Nationally, victim impact statements are now commonplace. Victims and their families now have more of a voice in the justice system.

Chin’s death spurred Pan-Asian American activism across the U.S., leading to the eventual founding of organizations like Asian Americans Advancing Justice in 1991 and Stop Asian American Pacific Islander Hate in 2020. During the COVID-19 pandemic, Stop AAPI Hate recorded violence against Asians happening in the U.S. and educated people about anti-Asian racism.

Today, Asian Americans fight for social justice through organizations like these and 18 Million Rising, a group that advocates for racial justice for Asian Americans and all marginalized people.

This is the lasting legacy of Vincent Chin.

Los guardabosques están quemando el desierto en Australia para evitar que se propaguen incendios intensos y destructivos

Source: The Conversation – (in Spanish) – By Rohan Fisher, Research fellow, Charles Darwin University

Aunque todavía es invierno, la temporada de incendios ya ha comenzado en el árido centro de Australia. Aproximadamente la mitad del Parque Nacional Tjoritja West MacDonnell, al oeste de Alice Springs, se ha quemado este año.

La propagación de la hierba Cenchrus ciliaris se considera un factor clave. Esta planta invasora ha sido clasificada como la mayor amenaza medioambiental para las culturas y comunidades indígenas australianas debido al daño que puede causar al desierto.

Las lluvias generalizadas asociadas al ciclo climático de La Niña provocan un auge en el crecimiento de esta especie vegetal. Cuando vuelven los periodos de sequía, las plantas y la hierba se secan y se convierten en combustible potencial para incendios masivos.

Estos incendios a menudo pasan desapercibidos porque casi todos los australianos viven cerca de la costa. Pero pueden ser enormes. En 2011, se quemaron más de 400 000 kilómetros cuadrados, aproximadamente la mitad del tamaño de Nueva Gales del Sur.

Después de tres años de lluvias provocadas por La Niña, nos encontramos en una situación similar, o incluso peor. Las autoridades responsables de la lucha contra incendios advierten de que hasta el 80 % del Territorio del Norte podría arder esta temporada de incendios.

Por eso, decenas de grupos de guardabosques indígenas de 12 áreas protegidas indígenas han estado trabajando duro en una colaboración sin precedentes, quemando para reducir la carga de combustible antes del calor del verano. Hasta ahora, han quemado 23 000 kilómetros cuadrados en los desiertos de Great Sandy, Tanami, Gibson y Great Victoria.

Quema de tierras áridas

Australia cuenta actualmente con 82 áreas protegidas indígenas, que abarcan más de 87 millones de hectáreas de tierra. Eso supone la mitad de toda la reserva de territorio protegido, y está creciendo rápidamente como parte de los esfuerzos para proteger el 30 % de las tierras y aguas de Australia para 2030. Estas áreas son gestionadas por grupos indígenas, y el fuego es una parte vital de la gestión.

Esta animación muestra las quemas de controladas realizadas por guardabosques indígenas en el desierto de Tanami en 2023. North Australia Fire Information, firenorth.org.au.

El objetivo es proteger contra los devastadores incendios forestales de verano, que son más destructivos. Sin los guardabosques indígenas que gestionan de forma experta los desiertos mediante la gestión de incendios a escala paisajística, estas tierras protegidas correrían el riesgo de deteriorarse.

Como dice Braeden Taylor, coordinador de Karajarri Ranger:

Un gran incendio forestal lo destruye todo, destruye el país. El primer objetivo es quemar un poco el suelo y luego quemar desde el aire, de esa manera sabemos que todo está protegido. Con el helicóptero y el avión, podemos acceder a zonas del país a las que es difícil llegar en vehículo. Puede que no se haya quemado en mucho tiempo y podemos romper esta tendencia.

Es bueno trabajar con otros grupos. Los incendios que se inician en su lado pueden llegar hasta nosotros y los incendios en el nuestro pueden llegar hasta ellos. Trabajando juntos nos protegemos mutuamente, cuidando de nuestros vecinos.

Entonces, ¿cómo recorren los guardabosques distancias tan largas? Estas áreas protegidas son extremadamente remotas. A menudo no hay acceso por carretera o este es muy limitado. Por lo tanto, trabajan desde el aire y, cuando es posible, desde tierra. El programa de incendios forestales de los guardabosques se basa en helicópteros y dispositivos incendiarios. Este año, han pasado 448 horas en el aire, recorriendo 58 457 kilómetros y lanzando 299 059 dispositivos incendiarios.

Cuando los incendiarios tocan el suelo, comienzan a arder. No todos los incendiarios alcanzan el lugar adecuado, por lo que se necesita tiempo para garantizar que se produzca una buena combustión. Estas tierras áridas suelen tener más hierba que árboles, por lo que los incendios se desplazan por el suelo y no alcanzan una intensidad excesiva.

quemas aéreas

Los guardabosques combinan las quemas aéreas con quemas terrestres a pequeña escala utilizando antorchas de goteo alrededor de las zonas sensibles. El objetivo es garantizar la protección de los sitios culturales y de especies amenazadas como el bilbi, el perico nocturno y el gran eslizón del desierto.

Esto es de vital importancia, dado que alrededor del 60 % de las especies de mamíferos del desierto ya se han extinguido en los últimos 250 años, mientras que muchas otras han visto reducida su área de distribución. Los cambios en los regímenes de incendios son un factor importante en estas disminuciones.

El fuego puede forjar la comunidad

Estos proyectos de quema que abarcan todo el desierto brindan a los propietarios tradicionales la posibilidad de ver el país, compartir su cultura y transmitir sus conocimientos de generación en generación.

Como dice Ronald Hunt, guardabosques de Ngaanyatjarra:

Cuando quemamos, se limpia toda la hierba espinosa y, cuando llega la lluvia, todo vuelve a crecer fresco. Es bueno para los animales, los alimentos silvestres y todo lo demás. Es bueno usar el helicóptero para llegar a lugares de difícil acceso. Es bueno trabajar junto con otros grupos, compartir historias y cuidar el país. Ellos tienen sus historias y nosotros las nuestras, y luego nos unimos para trabajar.

En los últimos años, ha habido un gran interés por la gestión indígena de los incendios, especialmente tras la devastación causada por los incendios del “verano negro” de 2019-2020.

El objetivo es pasar de los incendios incontrolados, en los que se acumula combustible hasta que se producen grandes incendios forestales devastadores, a los incendios controlados, regímenes de incendios basados en la cultura y dirigidos por los propietarios tradicionales.

Estos incendios se realizan con regularidad, con pequeños incendios de diversa intensidad que producen un mosaico a pequeña escala de vegetación en diferentes etapas de recuperación y mantienen la vegetación que no se ha quemado durante mucho tiempo como refugios seguros para la fauna y la flora.

Investigaciones recientes muestran que el retorno a estos regímenes de incendios adecuados a escala paisajística está teniendo un efecto real. En las zonas donde se lleva a cabo, el paisaje desértico está volviendo a un patrón complejo de quemas en mosaico, similar al que existía antes de la colonización.

Estos esfuerzos a gran escala deberían hacer que el país se mantenga saludable y a prevenir los peligrosos incendios.

Tit-for-tat gerrymandering wars won’t end soon – what happens in Texas and California doesn’t stay there

Source: The Conversation – USA – By Gibbs Knotts, Professor of Political Science, Coastal Carolina University

Congressional redistricting – the process of drawing electoral districts to account for population changes – was conceived by the Founding Fathers as a once-per-decade redrawing of district lines following the decennial U.S. census. Today it has devolved into a near-constant feature of American politics – often in response to litigation, and frequently with the intent of maintaining or gaining partisan advantage.

Polls show widespread public disapproval of manipulating political boundaries to favor certain groups, a process known as gerrymandering. However, we currently see little hope of preventing a race to the bottom, where numerous states redraw their maps to benefit one party in response to other states drawing their maps to benefit another party.

The most recent round of tit-for-tat gerrymandering began in Texas. After drawing their post-census congressional maps in 2021, Republicans in the Texas Legislature, at President Donald Trump’s behest, are advancing a new set of maps designed to increase the number of Republican congressional seats in their state. The goal is to help Republicans retain control of the U.S. House of Representatives in the 2026 midterm elections by converting five Democratic seats to ones that will likely result in a Republican victory.

In response, California Democratic Gov. Gavin Newsom is pushing to redraw his state’s map. Under Newsom’s plan, Democrats could gain five House seats in California, offsetting Republican gains in Texas. The California Legislature approved the new maps on Aug. 21 and Gov. Newsom signed the bills that day. Next, the maps will be presented to California voters on the November 2025 ballot for approval.

Newsom vows that he isn’t trying to disband the independent redistricting process that California enacted in 2021. Rather, he proposes to shift to these partisan gerrymandered maps temporarily, then return to independent, nonpartisan redistricting in 2031.

Democrats in Illinois and New York, and Republicans in Indiana, Missouri and South Carolina, have signaled that they may follow Texas and California’s leads. Based on our research on politics and elections, we don’t expect that the wave will stop there.

Gerrymandering dates back to struggles over U.S. foreign policy in the early 1800s and is named for a signer of the Declaration of Independence, Elbridge Gerry.

Rules for mapmakers

Redistricting has always been an inherently political process. But the advent of widespread, easily accessible computer technology, increasingly predictable voting patterns and tight partisan margins in Congress have turbocharged the process.

There are ways to tweak this gerrymandering run amok and perhaps block a bad map or two. But none of these approaches are likely to stop partisan actors entirely from drawing maps to benefit themselves and their parties.

The most obvious strategy would be to create guardrails for the legislators and commissions who draw the maps. Such guidelines often specify the types of data that could be used to draw the maps – for example, limiting partisan data.

Anti-gerrymandering rules could also limit the number of political boundaries, such as city or county lines, that would be split by new districts. And they could prioritize compactness, rather than allowing bizarrely-shaped districts that link far-flung communities.

These proposals certainly won’t do any harm, and might even move the process in a more positive direction, but they are unlikely to end gerrymandering.

For example, North Carolina had an explicit limitation on using partisan data in its 2021 mapmaking process, as well as a requirement that lawmakers could only draw maps in the North Carolina State Legislative Building. It was later revealed that a legislator had used “concept maps” drawn by an aide outside of the normal mapmaking process.

In a world where anyone with an internet connection can log onto free websites like Dave’s Redistricting to draw maps using partisan data, it’s hard to prevent states from incorporating nonofficial proposals into their maps.

Courts and commissions

A second way to police gerrymandering is to use the courts aggressively to combat unfair or discriminatory maps. Some courts, particularly at the state level, have reined in egregious gerrymanders like Pennsylvania’s 2011 map, which was overturned in 2018.

At the national level, however, the U.S. Supreme Court ruled in Rucho v. Common Cause in 2019 that partisan gerrymandering claims presented “political questions beyond the reach of the federal courts” and ultimately were better suited to state courts. There are still likely to be claims in federal courts about racial dilution and other Voting Rights Act violations in gerrymanders, but the door to the federal courthouse for partisanship claims appears to be closed for the time being.

A third option is for states to hand map-drawing power to an independent body. Recent studies show that independent redistricting commissions produce maps that are more competitive and fairer. For example, a nonpartisan scholarly review of the 2021-2022 congressional and state legislative maps found that commissions “generally produce less biased and more competitive plans than when one party controls the process.”

Commissions are popular with the public. In a 2024 study with political scientists Seth McKee and Scott Huffmon, we found that both Democrats and Republicans in South Carolina preferred to assign redistricting to an independent commission rather than the state Legislature, which has been in Republican control since 2000.

Studies using national polling data have also found evidence that redistricting commissions are popular, and that people who live in states that use commissions view the redistricting process more positively than residents of states where legislators draw congressional lines.

A national solution or bust

While redistricting commissions are popular and effective in states that have adopted them, current actions in California show that this strategy can fail if it is embraced by some states but not others.

Unfortunately, there is no simple solution for tit-for-tat gerrymandering. Litigation can help at the margins, and independent redistricting can make a difference, but even the best intentions can fail under political pressure.

The only wholesale solution is national reform. But even here, we are not optimistic.

A proportional representation system, in which seats are divided by the portion of the vote that goes to each party, could solve the problem. However, removing single-member districts and successfully implementing proportional representation in the United States is about as likely as finding a hockey puck on Mars.

A national ban on gerrymandering might be more politically palatable. Even here, though, the odds of success are fairly low. After all, the people who benefit from the current system would have to vote to change it, and the filibuster rule in the Senate requires not just majority but supermajority support.

So, brace for what’s about to come. As James Madison famously observed, forming factions – groups of people united by a common interest that threatens the rights of others – is “sown in the nature of man.”

Gerrymandering helps factions acquire and retain power. If U.S. leaders aren’t willing to consider a national solution, it won’t disappear anytime soon.

Los trabajos de la IA para sostener el mundo

Las inteligencias artificiales trabajan para conseguir materiales sostenibles en un mundo amenazado. Pexels, CC BY

Probablemente usted ya use ChatGPT para pedirle una receta, resolver una duda, preparar una clase o entender un tema complicado. Pero el poder de las IA generativas va mucho más allá.

En laboratorios, centros tecnológicos e industrias de todo el mundo, estamos utilizándolas para afrontar algunos de los mayores desafíos del planeta: generar energía de forma más eficiente, reducir las emisiones del transporte y diseñar materiales con menor impacto ambiental. Las IA están ayudándonos a imaginar soluciones posibles a las que los humanos no podemos llegar solos.

En mi campo de especialidad, la inteligencia artificial está dando forma conceptual a los materiales con los que construiremos un futuro que pueda ser sostenible.

Materiales en condiciones extremas

Uno de los grandes retos de la transición energética es encontrar materiales capaces de soportar condiciones extremas. Lo vemos, por ejemplo, en la energía solar de concentración, una interesante alternativa de renovables que almacena calor en sales fundidas para generar electricidad incluso cuando no hay sol.

Hoy se utilizan sales de nitratos que operan hasta 560 °C, pero se investigan cloruros fundidos, capaces de trabajar a 780 °C y almacenar más energía. El problema es que a esa temperatura se vuelven altamente corrosivos, y los metales convencionales no resisten durante largos periodos.

Algo parecido ocurre en el sector de la aeronáutica. Las turbinas de los aviones funcionan a temperaturas altísimas: cuanto mayor es la temperatura, mayor la eficiencia, menos combustible se consume y menos emisiones se generan.

Pero superar los 1 000 °C exige materiales que no se deformen ni se oxiden bajo condiciones extremas. En ambos casos –turbinas y sales corrosivas– necesitamos metales que aún no existen en el mercado.

Las aleaciones de alta entropía

Aquí entran en escena las aleaciones de alta entropía, un tipo de materiales que desde 2004 ha revolucionado la metalurgia.

A diferencia de las aleaciones tradicionales, formadas en torno a un elemento principal como hierro o níquel, estas combinan cinco o más elementos en proporciones similares. Este cambio abre un espacio de diseño casi infinito abarcando un gran número de combinaciones posibles en toda la tabla periódica, lo que da lugar a propiedades diversas como gran resistencia mecánica a altas temperaturas o excelente comportamiento frente a corrosión y oxidación.

La IA permite evaluar millones de composiciones de forma rápida, identificando las más prometedoras y reduciendo el tiempo necesario para pasar de una hipótesis a un material real. Lo que antes era un laberinto inabarcable ahora se recorre con brújula.

Por ejemplo, si lo que buscamos en las centrales termosolares es una aleación capaz de resistir los cloruros fundidos a 780 °C, o si pretendemos mantener su resistencia mecánica por encima de los 1 000 °C en una turbina de un avión, la IA puede cribar el espacio de opciones y señalar los candidatos más viables.

La dependencia de China para las baterías

También en el campo de las baterías se hace evidente la urgencia de innovar en materiales, y las IAs están trabajando en ello.

La creciente electrificación del transporte y el despliegue de tecnologías de almacenamiento energético dependen hoy en gran medida de materiales críticos como el litio, el cobalto, el níquel o el grafito, empleados en baterías de iones de litio.

Sin embargo, estos elementos no solo plantean desafíos ambientales y tecnológicos, sino también geopolíticos.

La cadena de suministro está fuertemente concentrada, con China controlando buena parte del procesado y refinado global de muchos de estos materiales estratégicos, así como una influencia creciente sobre la extracción de cobalto en África Central. Esta dependencia limita la autonomía tecnológica de regiones como Europa y las expone a tensiones comerciales o restricciones de exportación, como ya ha ocurrido con otros metales clave como el galio o el germanio.

El desarrollo de nuevas composiciones que reduzcan o eliminen la necesidad de estos elementos se ha convertido en una prioridad científica e industrial.

Son esenciales nuevos materiales para electrodos o electrolitos sólidos, más abundantes, reciclables y con menor huella ambiental, para garantizar baterías más sostenibles, accesibles y resistentes a los vaivenes del contexto internacional.

Solo con IA

La inteligencia artificial, aplicada al diseño de materiales, abre una vía prometedora para identificar alternativas con propiedades funcionales similares, pero fabricadas a partir de elementos más seguros, más locales y más sostenibles.

El reto, sin embargo, es explorar ese océano de combinaciones. Con métodos tradicionales basados en ensayo y error resultaría lento y costoso.

El alimento de las inteligencias artificiales

Diseñar con inteligencia artificial no significa pulsar un botón y obtener la respuesta perfecta. Todo depende de los datos disponibles. Generar información fiable mediante experimentos, estandarizar bases de datos y compartir resultados entre centros de investigación es hoy una prioridad. Sin esa base, los modelos de IA no pueden aprender ni producir predicciones sólidas.

Cuando no se dispone de datos experimentales, otra herramienta esencial es la simulación computacional. Modelos físicos y químicos permiten anticipar cómo se comportaría un material bajo ciertas condiciones y generar datos sintéticos que alimentan a los algoritmos de IA. De este modo, el progreso no depende solo de lo ya probado en el laboratorio, sino también de lo que puede predecirse con ayuda de la física.

Descubrimientos guiados por el diseño

Este enfoque encaja con lo que se denomina design-driven discovery, o descubrimiento guiado por el diseño.

A diferencia de la lógica tradicional –llamada material-driven–, en la que se parte de un material existente y se observa qué propiedades tiene, el enfoque design-driven comienza definiendo qué propiedades necesitamos (por ejemplo, resistencia a la corrosión a 780 ⁰C en el caso de los paneles solares) para buscar después las combinaciones químicas capaces de cumplirlas.

En lugar de descubrir lo que un material puede hacer, diseñamos directamente el que necesitamos que lo haga. Y la inteligencia artificial es la herramienta que hace posible ese giro.

La IA es una aliada estratégica si queremos que el mundo se sostenga.

Colombia necesita tecnología y digitalización para consolidar la paz

Source: The Conversation – (in Spanish) – By Roberto García Alonso, Associate Professor of Political Science, Universidad de La Sabana

La consolidación de la paz en Colombia no solo depende del cese de las hostilidades: pasa también por la creación de un horizonte de desarrollo económico y social que promueva la inclusión y el desarrollo sostenible. En este contexto, el concepto de Tech4Peace –o tecnologías para la paz, es decir, el uso estratégico de la tecnología para apoyar los procesos de paz– adquiere un papel central.

Investigaciones recientes resaltan que la conectividad digital, la ética empresarial y el emprendimiento constituyen ejes fundamentales para el desarrollo de proyectos de desarrollo en territorios afectados por el conflicto armado.

Inclusión digital y brechas estructurales

En América Latina, la brecha digital es una barrera para el desarrollo equitativo. Al analizar los 33 países de la región, vemos que el porcentaje de personas que usan internet es un predictor más relevante que la cobertura de banda ancha del índice de desarrollo humano (IDH), el indicador desarrollado por Naciones Unidas para medir el progreso de los países en salud, educación y nivel de vida.

En Colombia, esto cobra especial relevancia en los municipios más afectados por el conflicto armado, donde el acceso a internet sigue siendo limitado y desigual. En un intento de paliar la falta de oportunidades, el Estado colombiano ha establecido en ellos el Programa de Desarrollo con Enfoque Territorial (PDET).

Estudios recientes sugieren que priorizar el uso efectivo de internet en entornos rurales –mediante ofertas diferenciadas geográficamente y acompañamiento formativo– puede generar procesos de inclusión y participación ciudadana.

Automatización y empleo

En América Latina hay un claro contraste entre el bajo nivel de adopción de las nuevas tecnologías (particularmente de la IA) en los sectores tradicionales y el alto grado de innovación de las grandes empresas.

La transformación digital es un pilar para el desarrollo económico y social de las regiones y, además, tiene implicaciones medioambientales. La adopción responsable de la inteligencia artificial requiere, además de infraestructura, formación técnica, adaptaciones en la cultura corporativa y desarrollo de marcos éticos, soberanía digital y una gran disponibilidad de energía eléctrica y agua.

¿Puede la IA ser peor para el planeta que los maratones de series?


Un estudio basado en encuestas a trabajadores colombianos de empresas medianas y grandes analizó el papel que juegan valores humanos como la honestidad, la colaboración y el compromiso en los avances de la digitalización industrial (Industria 4.0) y en la percepción de seguridad laboral de los trabajadores.

Frente a los discursos que avisan de los riesgos de la automatización y la IA en el futuro del trabajo, los resultados de esta investigación muestran que dichos valores funcionan como atenuantes frente al miedo al reemplazo laboral y abren la posibilidad de una adaptación tecnológica ética y sostenible.

Esta evidencia empírica respalda la necesidad de diseñar políticas públicas que fomenten la relación entre la tecnología y la ética organizacional. Colombia, a través de sus planes nacionales de desarrollo, ha priorizado la actualización del talento humano y la transformación digital como claves para la productividad en contextos digitales.

Inteligencia artificial para el bien común

La aplicación de IA genera transformaciones disruptivas no solo para el sector privado sino también para el sector público. Estudios recientes indican que el uso de la IA puede mejorar la eficacia de las políticas y los procesos públicos tanto por la reducción de costes sino como por la capacidad de analizar datos, reconocer patrones sospechosos y emitir alertas a las autoridades. Así, su aplicación podría transformar las políticas públicas en países en desarrollo, como los de la región de América Latina y el Caribe.

En medio de las preocupaciones actuales sobre la ética en la digitalización y la privacidad de los datos, el Estado colombiano ha desarrollado marcos normativos e institucionales para el uso de la IA:

  • El marco ético para la IA, que considera factores como la transparencia, la privacidad, el control humano de las decisiones, la seguridad, la responsabilidad, la no discriminación, la inclusión, la protección de los derechos de los niños, niñas y adolescentes, y el beneficio social.

  • La política nacional de inteligencia artificial.

Digitalización y emprendimiento

El emprendimiento es una herramienta eficaz para reconstruir el tejido social en zonas posconflicto. Crear empresas genera empleo y dinamiza las economías locales. Sin embargo, en un mundo cada vez más digitalizado, para que eso ocurra es clave el fortalecimiento de capacidades digitales.

Las nuevas tecnologías ofrecen a las comunidades más vulnerables una vía de inclusión económica (por ejemplo, a través del desarrollo del comercio electrónico de los productos locales: artesanías, producción agrícola, etc.). No obstante, para ello se necesita acompañamiento técnico y visibilizar el trabajo y el producto desarrollado por dichas comunidades.

Sostenibilidad ambiental, equidad social y satisfacción personal, bases de una alternativa al desarrollo


Una agenda para la innovación

Incorporar las tecnologías digitales en contextos posconflicto no debe ser vista solo como una apuesta por la eficiencia: es también una oportunidad para la construcción de la paz en Colombia. Con el desarrollo de políticas de conectividad y marcos éticos robustos, y el uso estratégico de las aplicaciones de IA, los desafíos estructurales se pueden transformar en oportunidades de desarrollo sostenible.

Los trabajos recientes de investigadores colombianos ofrecen datos valiosos para la formulación de políticas públicas y la implementación de proyectos de Tech4Peace en el país. En última instancia, una paz duradera requiere no solo la ausencia de violencia, sino también de saber aprovechar las oportunidades que la transformación digital ofrece para la construcción de paz en los territorios que se han visto afectados por la violencia.

5 vital leadership takeaways from the life of Chief Poundmaker

Source: The Conversation – Canada – By Andrew J. Karesa, Adjunct Professor, Indigenous Business, The King’s University Canada

In the 21st century, leadership is typically framed in the position of power, strategy and authority and oftentimes considered interchangeable with management.

What if there was a different way to perceive and demonstrate our leadership in a way that empowers and supports others?

For Pitikwahanapiwiyin (Chief Poundmaker), leadership was about something more: it was about service, peace and an unwavering, relentless commitment to his people.

Throughout the late 1800s, Cree Chief Poundmaker used his unique leadership abilities to navigate political and cultural tensions while successfully advocating for the survival of his community. His legacy, while often misunderstood or unknown, has the potential to provide significant value in the leadership development of contemporary leaders globally.

Legacy of leadership, love, conciliation

Because Chief Poundmaker is a distant relative, my family often discusses him, but we lacked the intimate knowledge of his story and experiences. The pursuit of understanding my great-great-granduncle has led me to see that how we currently describe leadership is missing some important elements.

In my recent article, “Poundmaker — A Legacy of Leadership, Love and Conciliation,” I explore how considering the events of Poundmaker’s life can be used to understand how specific leadership traits give us new insights when seen against the current leadership paradigms. This is accomplished by using a two-eyed seeing (Etuaptmumk) approach, blending Indigenous and western leadership theory to make insights relevant to multiple audiences. The article is published in Indigenous Business and Public Administration.

In western society, leadership is typically viewed as either based on governance and process, or connection and collaborative relationships.

On the other hand, Indigenous leadership is a temporary “sphere of influence” that is based in our need-fulfilling roles within a community in order to ensure communal well-being.

Lesson 1: Embrace diverse perspectives

Before he was a chief, Poundmaker went through a process of adult adoption to become the son of Chief Crowfoot and a member of the Blackfoot Confederacy. This process of adult adoption was not uncommon, according to my community discussions, but typically happened within the same communities. Cree would adopt Cree, Blackfoot would adopt Blackfoot. In this case, the adoption of a Cree individual by a Blackfoot chief led to a historic moment politically and culturally.

This adoption set the stage for further unity between Cree and Blackfoot nations and an ability for Poundmaker to navigate multiple worldviews to make effective leadership decisions.

For a modern leader, embracing different perspectives is important. It builds team trust and fosters long-term success personally and organizationally. Effective leadership requires that an individual can step outside their comfort zone to engage with different perspectives, ensuring understanding and unity.

Lesson 2: Balance firm advocacy with strategic engagement

During the 1876 negotiation of Treaty 6 with the Crown, Poundmaker was a fierce defender of Indigenous land rights, famously stating “this is our land, not a piece of pemmican to be cut off and given in little pieces.” While he believed that his people should not have to give up any of their land, he also recognized that engagement with the Crown was necessary for the Cree’s long-term survival.

Today, leaders also face dilemmas calling for high-stakes decisions: Should we hold firm to our values or give in for a strategic reason?

Poundmaker’s example shows that strong leadership is not about all or nothing. Instead, it is about being deliberate in choosing when to push back and when it is time to engage.

Lesson 3: Prioritize peace and long-term consequences

During the Battle of Cut Knife in 1885, the attacking 325 Canadian troops fled after the unexpectedly strong defence presented by the Cree and Assiniboine camps.

As his troops were ready to chase down the retreating soldiers, Poundmaker made a choice that, while being profound, is very difficult. Instead of leading to more bloodshed, he told his warriors to stand down and prioritize peace over vengeance.

This moment of restraint is important for the modern leader. Often, our acts of retaliation or aggression lead to short-term gains but cause long-term losses.

Regardless of the industry or space, choosing de-escalation over conflict, while difficult, can prevent lasting damage and open doors for future reconciliation.

(Archives of Manitoba/Big Bear 3/N16092).

Lesson 4: Lead with compassion and community focus

Poundmaker’s leadership was rooted in service to his community and the overall well-being of his people. During the North-West Resistance, he sought food relief for the starving Cree communities instead of participating in a violent rebellion. This was further emphasized during his trial on felony treason charges for his actions at the Battle of Cut Knife, when he maintained: “Everything I could do was done to stop bloodshed.”

Modern leaders are often pressured to focus on financial or political gains instead of the benefit of their people. Poundmaker’s leadership is a reminder that sustainable success comes from putting our people first. Through a compassionate, community-centred approach, you can create loyalty, resilience and long-term success.

Lesson 5: Stand firm in principles for lasting impact

Poundmaker was wrongly convicted of felony treason and sentenced to three years in prison. He accepted this punishment knowing that his people were safe. Ultimately, the poor prison conditions contributed to his worsening health, in part leading to his death a few months later.

In 2019, the Canadian government formally exonerated Chief Poundmaker and recognized the injustices he faced.

(CU1124754/Glenbow Archives, University of Calgary)

While it took more than a century, his story proves that principled leadership outlasts momentary defeats.

Today, leaders can be inspired by this. When we choose to stand firm in our values, we may not see immediate victories. We may see struggles, but what’s important is doing what’s right. Regardless of whether this relates to social justice, ethical business practices or organizational change, leaders must be prepared to hold their ground when it matters most.

Chief Poundmaker’s leadership was rooted in love, reconciliation and an unwavering commitment to his people. His ability to unify nations, navigate high-stakes negotiations and prioritize peace over conflict offers timeless leadership lessons for the modern leader.

In our world, which is often divided by power struggles and short-term thinking, Poundmaker’s legacy should challenge us to lead differently — with humility, courage and a focus on the greater good.

The question we as leaders must ask ourselves is: what kind of leader do we want to be? Poundmaker’s example gives us a path forward.

Wildfire disasters are increasingly in the news, yet less land is burning globally – here’s why

Source: The Conversation – USA (2) – By Mojtaba Sadegh, Associate Professor of Civil Engineering; Senior Fellow at the United Nations University Institute for Water, Environment and Health, Boise State University

Worldwide, an estimated 440 million people were exposed to a wildfire encroaching on their home at some point between 2002 and 2021, new research shows. That’s roughly equivalent to the entire population of the European Union, and the number has been steadily rising – up 40% over those two decades.

With intense, destructive fires often in the news, it can seem like more land is burning. And in parts of the world, including western North America, it is.

Globally, however, our team of fire researchers also found that the total area burned actually declined by 26% over those two decades.

How is that possible?

We found the driving reasons for those changes in Africa, which has the vast majority of all land burned, but the total burned area there has been falling. Agricultural activities in Africa are increasingly fragmenting wildland areas that are prone to burning. A cultivated farm field and roads can help stop a fire’s spread. But more farms and development in wildland areas also means more people can be exposed to wildfires.

Drawing on our expertise in climate and wildfire sciences and geospatial modeling, we analyzed global wildfire activity over the past two decades. The results highlight some common misperceptions and show how the fire risk to humans is changing.

Global burned area down, intense fires up

Wildfire is a natural process that has existed for as long as vegetation has covered the Earth. Occasional fires in a forest are healthy. They clear out dead wood and leaf and branch litter, leaving less fuel for future fires to burn. That helps to keep wildfires from becoming too intense.

However, intense fires can also pose serious threats to human lives, infrastructure and economies, particularly as more people move into fire-prone areas.

North and South America have both experienced a rise in intense wildfires over the past two decades. Some notable examples include the 2018 Camp Fire in California and the 2023 record-breaking Canadian wildfires, which generated widespread smoke that blanketed large parts of Canada and the eastern United States, and even reached Europe.

The increase in intense wildfires aligns with the intensification of fire weather around the world. Heat, low humidity and strong winds can make wildfires more likely to spread and harder to control. The number of days conducive to extreme fire behavior and new fire ignitions has increased by more than 50% over the past four decades globally, elevating the odds that the amount of land burned in a particular region sets a new record.

But fire weather is not the only influence on wildfire risk. The amount of dry vegetation, and whether it’s in a continuous stretch or broken up, influences fire risk. So do ignition sources, such as vehicles and power lines in wildland areas. Human activities can start fires and fuel climate change, which further dries out the land, amplifying wildfire activity. Fire suppression practices that don’t allow low-intensity fires to burn can lead to the accumulation of flammable vegetation, raising the risk of intense fires.

North America is a fraction of total burned area

In recent years, a growing number of wildfire disasters in North America, Europe and Australia have captured global attention. From the deadly 2025 Los Angeles fires to the devastating 2019-2020 Australian bushfires and the 2018 wildfire in Athens, Greece, flames have increasingly encroached upon human settlements, claiming lives and livelihoods.

However, wildfire exposure isn’t limited to these high-profile regions − we simply hear more about them.

The United States, Europe and Australia collectively account for less than 2.5% of global human exposure to wildfire. Human exposure to fire occurs when people’s homes fall directly within the area burned by a wildfire.

In stark contrast, Africa alone accounts for approximately 85% of all wildfire exposures and 65% of the global burned area.

Remarkably, just five central African countries – the Democratic Republic of Congo, South Sudan, Mozambique, Zambia and Angola – experience half of all global human exposure to wildfires, even though they account for less than 3% of the global population. These countries receive sufficient moisture to support plant growth, yet they are dry enough that trees and plants burn in frequent fires that in some places occur multiple times per year.

Regional trends and drivers of wildfire

We found that wildfire exposure increased across all continents except Europe and Oceania, but the underlying drivers of the increase varied by region.

In Africa, agricultural expansion has led to more people living in fire-prone areas.

In North America, particularly the United States, intensifying fire weather – the hot, dry, windy conditions conducive to spreading fires – has led to increasingly uncontrollable wildfires that threaten human settlements.

In South America, a combination of rising drought frequency and severity, intensifying heat waves and agricultural expansion has amplified wildfire intensity and increased the population in fire-prone regions.

In Asia, growing populations in fire-prone areas, combined with more days of fire-friendly weather, led to increased human exposure to wildfires.

In contrast, Europe and Oceania have seen declining wildfire exposures, largely due to more people moving to cities and fewer living in rural, fire-prone zones.

What to do about it

Communities can take steps to prevent destructive wildfires from spreading.

For example, vegetation management, such as prescribed fires, can avoid fueling intense fires. Public education, policy enforcement and engineering solutions – such as vegetation reduction and clearance along roads and power lines – can help reduce human-caused ignitions.

As climate change intensifies fire weather and people continue to move into fire-prone zones, proactive mitigation will be increasingly critical.
