Visite du pape Léon en Afrique : un théologien met en avant trois réalités auxquelles l’Église catholique doit faire face

Source: The Conversation – in French – By Stan Chu Ilo, Research Professor, World Christianity and African Studies, DePaul University

La décision du pape Léon de se rendre en Afrique, l’une des premières destinations dès le débutson pontificat, témoigne de l’importance du continent dans le catholicisme mondial. Sa visite d’avril 2026 reflète à la fois ses liens personnels avec l’Afrique et l’essor rapide du christianisme à travers le continent.

Son périple de 10 jours en Algérie, en Angola, au Cameroun et en Guinée équatoriale revêt également une importance historique. En Algérie, par exemple, le pape Léon marchera sur les traces d’Augustin d’Hippone (qui vécut vers l’an 400), son père spirituel, soulignant ainsi les racines africaines du christianisme.

Mais lorsque le pape a annoncé son voyage en Afrique en février 2026, rares étaient ceux qui auraient pu prévoir à quel point la situation sécuritaire mondiale allait se détériorer rapidement. Il existe un risque réel que les crises mondiales actuelles, telles que le conflit en Iran, attirent toute l’attention, éclipsant à la fois l’importance de la visite du pape Léon et les conflits persistants, souvent négligés, qui sévissent à travers l’Afrique.

La dernière visite papale en Afrique — celle de son prédécesseur, le pape François, en 2023 en République démocratique du Congo et au Soudan du Sud — visait également à attirer l’attention sur les guerres qui ravagent l’Afrique. Les vastes camps de réfugiés, partout sur le continent, rappellent la dure réalité des vies suspendues entre incertitude et souffrance.

Je suis un théologien africain et mes travaux examinent comment le catholicisme contemporain est en train de changer. Mes recherches vont au-delà du simple suivi des données démographiques de l’expansion chrétienne. Elles s’interrogent sur la manière dont les communautés chrétiennes, ancrées dans des cultures diverses, transforment les sociétés et les cultures à la lumière de l’Évangile.

En choisissant de se rendre en Afrique aujourd’hui, le pape Léon envoie un message clair : l’Afrique compte. L’Église catholique sur le continent peut saisir cette occasion pour établir des partenariats plus équitables et non paternalistes avec les Églises du Nord, où le nombre de fidèles est en déclin.

Les racines africaines du christianisme

Le christianisme n’est pas une importation récente en Afrique apportée par les missionnaires européens. Le continent offre depuis longtemps des racines culturelles, spirituelles et théologiques profondes au christianisme. Cela inclut la fuite en Égypte lorsque la vie de Jésus a été menacée par Hérode après sa naissance, ainsi que l’école catéchétique d’Alexandrie, le plus ancien centre d’enseignement supérieur chrétien au monde.

La visite du pape Léon rappelle avec force le rôle fondateur du continent dans la formation de l’Église, en particulier au cours de ses cinq premiers siècles.

De plus, l’Afrique abrite la population catholique qui connaît la croissance la plus rapide, estimée aujourd’hui à 280 millions de catholiques, soit 19,8 % de la population catholique mondiale.

Rien qu’en 2025, l’Église catholique africaine a enregistré 8,3 millions de nouveaux membres.

L’Afrique contribue de manière significative au capital humain mondial de l’Église. Le Nigeria, l’Afrique du Sud et la République démocratique du Congo figurent parmi les 10 premiers « pays d’origine » dans l’échange missionnaire du Sud vers le Nord.

Pape François : pourquoi son pontificat a marqué l’Afrique, les pauvres et les marginalisés du monde


Paul VI a été le premier pape moderne à se rendre en Afrique, en 1969. Il a déclaré que le moment était venu pour l’Afrique d’avoir « un christianisme africain ».

De nombreux catholiques africains voient dans ce discours une invitation adressée aux Africains à prendre la responsabilité de rendre le christianisme véritablement catholique et véritablement africain.

Plus tard, en 1995, le pape Jean-Paul II a affirmé que « l’heure de l’Afrique » était venue. Le pape Benoît XVI, lors de sa visite en Afrique en 2009, a décrit le continent comme un « poumon spirituel» pour un monde en crise.

Ces expressions traduisent une conviction commune : l’Église en Afrique a atteint sa maturité et s’impose comme une force spirituelle majeure dans l’expansion contemporaine du christianisme mondial.

Certains défis persistent

Le pape Léon n’est pas un inconnu sur le continent. Il a visité plusieurs pays africains au cours de ses deux mandats à la tête de l’Ordre de Saint-Augustin, dont le siège est à Rome.

Cependant, il sera confronté à un paradoxe persistant et troublant qui touche à la fois l’Église et la société au sens large. La croissance rapide du christianisme ne s’est pas systématiquement traduite par une amélioration des conditions de vie des populations. Si l’Église veut rester pertinente, elle doit incarner de manière plus convaincante le pouvoir transformateur de l’Évangile au sein des réalités vécues des sociétés africaines.

Elle doit répondre à l’imaginaire religieux changeant de nombreux chrétiens africains qui passent facilement des groupes chrétiens traditionnels comme le catholicisme au pentecôtisme et aux religions traditionnelles africaines. Cela signifie que l’Église catholique a besoin d’un moment d’introspection pour se demander si elle répond réellement aux besoins des fidèles. Est-ce une Église qui porte les récits et les blessures du peuple ?

Si elle ne s’attaque pas à la crise profonde de la foi et à la lutte pour la survie en Afrique que mènent tant de croyants vivant dans la pauvreté, l’Église risque de devenir un simple prestataire de services caritatifs. Elle pourrait au contraire être une force de transformation sociale plus profonde, de conversion religieuse et morale, et de renouveau spirituel.

Fin d’un catholicisme à sens unique ? L’Afrique post-François veut se faire entendre


La visite du pape Léon s’inscrit également dans des contextes politiquement sensibles.

Au Cameroun, le conflit de longue date dans les régions anglophones et le long règne du président Paul Biya ont suscité des inquiétudes. Une visite papale pourrait être interprétée comme une légitimation des structures du pouvoir que beaucoup considèrent comme répressives. Les décennies au pouvoir de Biya ont été associées à la manipulation électorale, à la répression de la dissidence et à la mainmise sur l’État.

Des tensions similaires existent en Guinée équatoriale. Le président Teodoro Obiang est au pouvoir depuis 47 ans. Son règne a été marqué par la répression de l’opposition dans un pays riche en pétrole mais profondément inégalitaire.

L’image de ces deux dirigeants de longue date aux côtés du pape Léon sera frappante. Elle soulèvera des questions. Mais elle offrira également au pape l’occasion de dire des vérités difficiles à entendre aux dirigeants qui détruisent l’Afrique.

En revanche, l’Angola offre un récit plus porteur d’espoir sur la reprise post-conflit. Il démontre comment la collaboration entre l’Église, l’État et la société civile peut déboucher sur des progrès graduels mais significatifs.

L’Afrique et l’avenir d’une Église à l’écoute

Malgré tout ce qui a été dit sur l’amour du pape François pour l’Afrique, il est frappant qu’à sa mort en avril 2025, aucun cardinal africain ne dirigeait de dicastère (département de niveau ministériel de l’administration centrale de l’Église catholique à Rome).

Pape François, le premier pontificat postcolonial dont le message résonne chez les Africains


Les Africains ne représentaient qu’à peine 12 % du Collège des cardinaux. Ses membres sont les conseillers les plus proches du pape et choisissent les nouveaux papes.

Le pape Léon a déjà commencé à remédier à ce déséquilibre au sein des commissions clés et des structures administratives en nommant des Africains à des postes d’influence réelle.

L’une des qualités les plus remarquables qui lui sont attribuées est sa capacité d’écoute. À mon avis, cette écoute doit faire face à trois réalités interdépendantes si l’Église en Afrique veut devenir un agent crédible de transformation.

Dépendance : Les paroisses et les programmes pastoraux en Afrique dépendent encore du soutien financier de l’Europe et de l’Amérique du Nord. C’est un obstacle majeur à l’émergence d’un christianisme africain mature et autonome. L’Église risque de reproduire des dynamiques de pouvoir asymétriques qui affaiblissent l’action humaine et la créativité pastorale.

Décolonisation : Les structures ecclésiales et les cadres théologiques hérités doivent être remis en question. Sans cela, l’Église ne sera pas enracinée dans les expériences vécues et les réalités des peuples africains.

Leadership : La crise du leadership en Afrique se reflète au sein de l’Église. Ce qu’il faut, c’est un leadership transformateur, humble et au service des autres, fondé sur la responsabilité, la transparence et le partage des responsabilités. Cela implique une plus grande prise en compte des voix et des atouts des laïcs, en particulier des femmes.

La visite du pape Léon constitue un moment clé pour l’Église catholique en Afrique. Va-t-elle rester un simple réceptacle du catholicisme mondial ou contribuer à en façonner l’avenir ?

Gray whales are dying in San Francisco Bay at an alarming rate – this isn’t normal

At least six gray whales have died in San Francisco Bay from mid-March to early April 2026. These deaths follow a pattern over the past few years, and they are raising concerns among marine biologists like us that 2026 is becoming another dangerous year for a struggling population.

The majority of eastern North Pacific gray whales migrate closely along the California coastline from their winter breeding grounds in Baja California, Mexico, to their summer foraging grounds in the Arctic.

These whales, which can grow to 90,000 pounds and over 40 feet in length, haven’t stopped over in San Francisco Bay consistently throughout history. When they have, it has coincided with years when their food supply in the Arctic was low.

Over the past few years, however, we have documented large numbers of gray whales in the waters of San Francisco Bay – and an alarmingly high mortality rate.

What’s killing the whales

San Francisco Bay is a busy urban waterway, with high-speed ferries, cargo ships, commercial fishing vessels and recreational watercraft. That makes it a dangerous place for slow-moving whales.

To monitor the gray whales, we conducted research surveys and collected photographs from whale-watching naturalists and community members who spotted whales in the bay. Gray whales have unique mottling patterns and markings on their sides and tails, some of which they’re born with and others they have accumulated over time.

We found that from 2018 to 2025, 114 individual gray whales visited San Francisco Bay for varying lengths of time, but very few of these whales were repeat visitors from year to year. This may be due, in part, to the high mortality rate in the bay.

At least 18% of the whales that we documented alive in San Francisco Bay from 2018 to 2025 later died in the area, and evidence suggests the mortality rate is actually higher.

Of the 70 dead whales included in this study, 30 of them had evidence of trauma associated with being hit by ships, but many other whales that died there couldn’t be reached to be examined. We also documented several living whales with injuries caused by vessels. Those injuries have the potential to affect a whale’s ability to thrive.

The whales aren’t recovering this time

Since 2016, the overall eastern North Pacific gray whale population has fallen by more than half, likely driven by the decline in the food the whales rely upon. Rising ocean temperatures and diminishing levels of sea ice are affecting both the quality and availability of the gray whales’ prey, which include crustaceans they scoop up as they dive along the seafloor.

When the eastern North Pacific gray whales suffered major die-offs in the past, including in the 1990s and early 2020s, the population rebounded. But the extremely low numbers of calves in recent years suggest the gray whales aren’t recovering as quickly this time, and that worries scientists.

EG: A Google search suggests the name of the lighthouse mentioned in the chart is the Piedras Blancas Light Station.

Some subgroups of eastern North Pacific gray whales, including the Pacific coast feeding group and North Puget Sound whales, known as the Sounders, feed in alternative areas south of the Arctic. The Sounders capitalize on very specific prey – ghost shrimp – in Puget Sound. When food is more scarce in the Arctic, they stay longer there and are often joined by other whales from the general population. While some researchers initially believed the whales entering the bay were from these groups, we found that wasn’t the case.

Vessel strikes also aren’t unique to San Francisco Bay. Two gray whales were found dead on the Oregon coast in April 2026, both malnourished and one with evidence of a ship strike. A malnourished young gray whale also died after swimming about 20 miles up the Willapa River in Washington state, reflecting the struggle as this population of gray whales searches for food across their migratory range.

What can be done to help the whales?

Other large whale species facing similar threats have been helped by management strategies, such as seasonal slow-speed zones during migration periods that go into effect when whales are present.

When vessels slow down to speeds of 10 knots or lower, studies show that can reduce the risk of vessel strikes by allowing more time for whales to get out of the way, or for captains to detect them and alter their course.

The National Oceanic and Atmospheric Administration has in recent years issued requests for ships to voluntarily reduce their speed to 10 knots in the Pacific Ocean off Monterey and San Francisco, but the limits haven’t been mandatory and typically haven’t started until May 1. The Port of Oakland also encourages shipping companies to keep their speed under 10 knots, but it’s also a recommendation, not a requirement.

More education to help boat operators learn how to avoid hitting whales, along with tools such as thermal cameras, could help reduce vessel strikes in San Francisco Bay.

As the population struggles to adapt to environmental changes, San Francisco Bay may look like an attractive feeding ground to nutritionally stressed or hungry whales. We hope our research and data from across the region will help marine resource managers and policymakers find ways to protect the whales that share this busy urban waterway.

How a new mapping tool helps Florida planners protect wildlife corridors as the state grows

Source: The Conversation – USA (2) – By Sarah Lockhart, PhD Candidate, Interdisciplinary Ecology, University of Florida

As Florida’s human population grows, wildlife increasingly has nowhere to go. Benjamin Klinger/iStock via Getty Images Plus

Florida added nearly 3 million residents from 2010-2020, making it the fastest-growing state in the United States during that time.

On any given day, a Florida county commission or municipality may approve a new subdivision, a transportation agency may select the route of a highway expansion, or a rancher may decide whether to sell land for development. As new neighborhoods, roads and infrastructure spread across the state, they reshape not only communities but also the natural systems wildlife depends on.

Each decision is local and incremental. But taken together, these choices determine whether wildlife can move across Florida’s landscapes to find food, reproduce and adapt to a changing climate – or become isolated in shrinking fragments of habitat.

In 2011, Florida eliminated the Department of Community Affairs, which had monitored and coordinated land use and development throughout the state. Since then, there has been limited oversight of local and county governments when it comes to urban planning and land development.

As conservation researchers, we study how scientific data can support real-world planning decisions. That led us to develop the Florida Ecological Connectivity Planning Viewer in collaboration with our colleagues at the University of Florida’s Center for Landscape Conservation Planning and GeoPlan Center. We call it the EcoCon.

This online mapping platform helps decision-makers and conservationists understand how land across Florida fits together as a connected ecological network. Seeing this network alongside a suite of other related planning and conservation data can help them avoid impacts that would disrupt or disconnect it.

A cautionary tale from the ‘Last Green Thread’

Scientists have known for decades that connected landscapes benefit both animals and people. Large, connected ecosystems help protect drinking water supplies, reduce flooding and support agriculture, recreation and tourism. They can also be more resilient to climate pressures, such as stronger storms and changing rainfall patterns.

The challenge today is not proving that connectivity matters. It is helping people see how thousands of everyday land-use decisions add up to create, or break, those connections.

A clear example of this challenge can be found in central Florida, about 20 miles southwest of Orlando. Since the early 1990s, conservation scientists have identified a narrow stretch of land known as the “Last Green Thread.” This thread is one of the few remaining opportunities to maintain a continuous ecological connection between protected lands in the Green Swamp, the source of four of Florida’s rivers, and the headwaters of the Everglades to the south.

This corridor still remains. But it is a shrinking sliver on its way to completely disappearing as land use decisions continue to make it less functional. An intact corridor helps species such as the Florida black bear, and potentially the endangered Florida panther, move between habitats. It also benefits other animals that are sensitive to fragmentation, including bobcats, otters, scrub jays, alligators and gopher tortoises.

No single decision has eliminated this corridor. Over time, however, development has gradually filled in significant parts of this landscape. Subdivisions and infrastructure have spread across multiple private properties and public jurisdictions. The result is a fragmented pathway between major conservation areas in south and central Florida.

A new way to see the landscape

Researchers have spent decades mapping wildlife habitat and ecological connections using geographic information systems. These digital tools help identify where important ecological links exist across landscapes.

But this data has not always been easy for planners, communities and landowners to access. Information may be scattered across agencies, universities and technical reports, or it may require expensive software tools and expertise to access.

When different decision-makers rely on different maps – or none at all – it becomes difficult to see how individual land-use decisions affect the larger ecological network.

This is where the EcoCon comes in.

With a few clicks, users can turn different layers on and off. These layers include wildlife movement pathways, protected conservation lands, wildlife crossings, water resources, agricultural areas and more. Instead of looking at these pieces separately, the EcoCon shows how they overlap.

The wildlife connectivity data comes from scientific models that estimate how animals move across the landscape. Using information such as land cover, habitat quality and barriers, including roads and development, these models highlight the routes animals are most likely to take between large natural areas.

By bringing this information together in a single, easy-to-use, publicly accessible mapping tool, the EcoCon helps planners see how proposed changes to the landscape might affect wildlife and natural resources.

Using the EcoCon isn’t about stopping development. Rather, it gives decision-makers a clearer picture so they can make informed, coordinated plans for growth in ways that better support both people and wildlife.

Tools like the EcoCon can also support broader conservation initiatives such as the Florida Wildlife Corridor, a statewide network of connected public and private lands that helps wildlife move across the state.

In fast-growing Florida, this visibility may be one of the most important tools for ensuring that wildlife and people can continue to share the same landscape in a rapidly changing world.

District school boards have become political hotbeds for book bans and more – here’s what they actually do

Election races for local school boards have become hotly contested in many states as they have become forums for debates over gender-identity discussions, immigrant students and even prayer at school events.

Liberal candidates largely swept school board elections on April 7, 2026, in politically contentious districts in Wisconsin, Missouri, Alaska and Oklahoma, where book bans, gender identity and prayer during school events were on the table.

Amy Lieberman, the education editor at The Conversation U.S., spoke with Carrie Sampson, a scholar of educational leadership and policy with an emphasis on school boards, to understand what school board members do and why these local elections carry weight for many parents, teachers and students.

What are district school boards?

School boards are the governing organization for local school districts. There are typically anywhere from five to 21 members of a school board in a district. On average, there are seven to nine members on a school board.

Overall, there are approximately 13,000 school districts and about 90,000 local school board members in the United States.

School board members are typically elected, but sometimes they are appointed by mayors or other local or state officials. They are representatives of their local communities, as well as trustees who make governing decisions about school district budgets, hiring and other issues like a school district’s educational priorities.

School board elections typically have relatively low voter turnout. Research shows that nearly 40% of school board elections go uncontested.

The majority of school board members are unpaid, but some receive a small stipend for their work. A handful of school boards, like in Los Angeles, for example, receive a relatively large salary.

What does a school board member’s day-to-day work look like?

School boards typically meet twice a month, often to deliberate over issues such as budget or policy decisions.

One of a school board’s major jobs in most districts is hiring and firing a district superintendent, who effectively acts as the CEO of the district.

In terms of fiscal decisions, a school district administrator often presents what budget allocations should be for schools, and a school board votes to approve or disapprove that.

Most school boards create agendas and vote on a range of issues that are not particularly controversial, like whether the district will adopt an after-school program.

Why does a school board’s work matter?

School boards can make some critical decisions that impact the lives of students, parents and teachers. Many school districts are dealing with issues around school closures. Ultimately, school boards decide whether they are going to close a school in a district.

Many school districts are experiencing declining student enrollment, in part because of birth rate declines. People also have more and more school options to pick from, be it private schools, charter schools or homeschooling.

Within the past few years, school boards have also gained a lot of attention about whether they should ban particular books from districts, and whether they should ban or approve certain curriculum.

What other controversial issues have they taken on in the past few years?

Years before COVID-19, school boards in some conservative communities took on questions about which bathroom transgender students in public schools should use. Another big issue is whether schools should allow transgender students to participate on gendered sports teams.

During the pandemic, a rising number of communities began to see school boards as critical decision-makers. School boards were often making decisions about whether to close or reopen schools. They were also voting on requirements related to mask mandates or vaccines. Even people who didn’t live in certain school districts showed up at board meetings to advocate for certain COVID policies.

During the Black Lives Matter protest movement in 2020, some conservative communities started to speak out against critical race theory and their fear that it was being taught in K-12 schools. Most teachers don’t actually instruct on critical race theory.

Around this time, two major school advocacy organizations emerged nationwide: Moms for Liberty and Defending Education, formerly known as Parents Defending Education. These groups tried to elect conservative school board members to take on issues like book bans – and in some cases did so successfully.

My colleague Gabriela Lopez and I wrote a research paper in 2024 about people’s attempts to recall school board members. In 2021, we found, there was an all-time high of 545 school board members who faced recall, mostly because of mask mandates and other COVID-related issues.

Another trend was that police arrested or charged at least 59 people due to unrest at school board meetings from May 2021 through November 2022.

Are school boards taking on more controversial issues than they used to?

Every era has a point at which these controversial issues come to the school board level.

School boards made critical decisions around school desegregation in the 1950s through the 1970s. My research with colleagues on this topic shows that while many districts were legally mandated to desegregate schools, it was often school boards that voted on how these schools would be desegregated. Some school boards voted on policies that placed the burden on Black children and their families. One school board in Virginia even temporarily closed the schools completely to avoid desegregation.

Twenty to 30 years ago, many school boards faced tension over whether and how schools should teach sex ed.

Today, a lot of the political controversy about school boards is more widely known, for a few reasons. First, more communities have access to school board meetings, since many are video recorded. Second, social media has amplified what school boards do. There are also more outside organizations, such as local chapters of Moms for Liberty, that have been involved with school boards.

School boards taking on controversial issues are more likely to be in suburban and racially diverse school districts, compared to their rural or urban counterparts.

A report in 2024 found that the cost of conflict among school boards nationwide in 2023-24 was nearly $3.2 billion, when considering the amount of turnover or security needed for school board meetings.

Cannabis legalization spurs innovation, but not always in ways that benefit patients or public health

Even after legalization, researchers face significant barriers to studying cannabis. Visoot Uthairam/Moment via Getty Images

Innovation in health care saves lives. But not all health innovations have enough evidence to actually benefit patients.

Barriers to innovation are often higher in illicit or restricted markets, including cannabis, stem cells and cryptocurrencies. Researchers face higher costs, limited access to raw materials and data, and stricter regulations.

Cannabis illustrates a particularly confusing tension between regulatory restrictions on one hand and research and innovation on the other.

While the U.S. federal government still classifies cannabis as having “no accepted medical use,” many states have legalized it for medical or recreational use. Meanwhile, the Department of Health and Human Services obtained a cannabis-related patent in 2003 covering potential medical uses of cannabis compounds for protecting the brain from damage or degeneration. The patent was exclusively licensed for commercialization.

Research and innovation on cannabis can take many forms. Clinical trials may study cannabis products as medical treatments, the effects of cannabis on its users, or factors related to abuse and dependence. Meanwhile, cannabis-related patents can be filed for wide-ranging purposes, such as chemical formulations, methods for production or new consumer products like edibles, beverages or vaporizers.

But do these innovations actually benefit consumers and patients?

We are economists studying how institutional changes affect innovation in different markets. Our recently published research found that legalization of recreational cannabis use appears to spur innovation, but primarily in ways that expand commercial opportunities rather than scientific understanding or health benefits for patients.

Cannabis’ evolving legality in the US

Cannabis is a plant that contains chemical compounds called cannabinoids. One such compound, tetrahydrocannabinol, or THC, produces psychoactive effects, while another compound called cannabidiol, or CBD, is often used to relieve anxiety and pain. However, there has been insufficient evidence on how effective cannabis products are in treating medical conditions, as well as a lack of consistent medical and dosing guidance.

At the federal level in the U.S., cannabis has been classified as a Schedule I drug for over a half-century. This classification indicates that the federal government considers cannabis to have a high potential for abuse and no accepted medical use.

As a Schedule I drug, there are significant restrictions on cannabis research. Researchers who seek to conduct cannabis-related clinical trials must obtain approval from both the Food and Drug Administration and the Drug Enforcement Administration, a process that can take over a year. They are also limited to using select varieties of cannabis obtained from federally authorized cannabis suppliers, and are generally prohibited from studying products available in state-authorized markets.

Cannabis interacts with the brain’s endocannabinoid system.

There are ongoing pushes to relax these restrictions. Meanwhile, cannabis has been legalized to varying extents in many states. California became the first state to pass a medical cannabis law in 1996, allowing qualified patients to grow, possess and use cannabis for medical purposes. Many states followed suit in the late 1990s and early 2000s. As of June 2025, 40 states allow medical cannabis use.

A number of states also allow recreational or nonmedical cannabis use among adults, which is regulated in similar ways to alcohol. Colorado and Washington enacted the first recreational cannabis laws in 2012, and there are 24 states that permit adults to use cannabis recreationally as of January 2026.

Altogether, the legal landscape for cannabis in the U.S. has varied considerably across states and over time. States with more permissive laws can lower the costs of medical research and product development with cannabis, even if federal drug scheduling continues to restrict access. For instance, one group of Washington State University researchers asked participants to independently purchase and smoke cannabis from a legal dispensary before returning to their lab for study.

State legalization and cannabis innovation

To systematically examine how state legalization affects cannabis-related innovation, we compiled and analyzed datasets tracking cannabis-related clinical trials and patent applications.

We distinguished different types of cannabis-related innovation. Specifically, we categorized cannabis-related clinical trials based on whether they focused on its potential as a treatment, its usage and effects, or its role in drug abuse. Similarly, we categorized cannabis-related patents based on whether they focused on chemical compounds, medical uses, methods or products.

We also assessed public health concerns across three measures: patents explicitly involving THC; patents with a high risk of misuse; and patents targeting consumers directly, such as high-potency formulations, edibles or vaporizers.

Then, we compared changes in cannabis-related innovation over time in states that legalized cannabis earlier with those in states that did so later or not at all. We measured innovation by counting the number of cannabis-related clinical trials and patent filings. We distinguished between medical and recreational legalization to assess how different policies affect innovation.

Overall, we found that when states legalize cannabis for recreational use, cannabis-related patents increase – but mostly in commercial-oriented areas rather than health-focused ones. Patents were concentrated in market-oriented innovations like cultivation equipment and consumer products, rather than in clinical or science-based research. We also found some evidence that these innovations may raise public health concerns.

Legalization did not result in meaningful increases in clinical trials. This suggests that barriers to cannabis-related clinical research – such as limited access to research-grade cannabis, limited funding and stigma around working with a federally controlled substance – remain substantial.

Gaps between research and product

As 420 – signifying April 20, a day celebrating cannabis culture – approaches each year, public attention turns toward the legal status of cannabis.

The legal landscape has evolved rapidly over the past few decades, and further changes are in the pipeline. Both the Biden and second Trump administrations have made efforts to reclassify cannabis as a Schedule III substance, which would indicate that it has an accepted medical use and low-to-moderate potential for dependence.

These reevaluations of the legality of cannabis come at a critical time. There has been an explosion of recreational cannabis products in recent years, including increasingly potent strains and a wider variety of ways to use cannabis. Meanwhile, critical research on the health and safety of cannabis use has lagged due to heavy restrictions accompanying Schedule I status.

This gap between medical research and product innovation can have significant public health consequences. The 2019 to 2020 outbreak of lung injuries related to e-cigarette or vape use was linked partly to the use of unregulated or illicit cannabis vaping products. These harms highlight the risks of allowing product innovation for controlled substances to outpace scientific understanding.

Policies that significantly reduce obstacles to clinical research can in turn help close the widening gap between cannabis markets and addressing their public health implications.

‘Bouncing back’ is a myth – resilience means integrating hard experiences into your life story, not ignoring them

When Maria looked at herself in the mirror for the first time after her mastectomy, she stood very still.

One hand rested on the bathroom counter. The other hovered near the flat space where her breast had been. The scar was raw and angry. The loss was quiet but enormous. Her body felt foreign.

In moments like these, people are often urged to be resilient – which can feel like being told to show no weakness, to push through no matter what. Or they imagine resilience as bouncing back: returning somehow unscathed to be the person you were before.

But standing in that bathroom, Maria knew there was no going back. And toughness wouldn’t change what had happened. The real question was how she could move forward, carrying this experience into her new reality.

Maria’s story, one I came to know personally, is far from unique. Loss, trauma and illness often bring the same wrenching questions of identity and the painful uncertainty of what comes next.

I’ve spent more than two decades studying resilience, particularly among individuals and families navigating these kinds of life-changing events. I am also a four-time cancer survivor and author of a new book, “Falling Forward: The New Science of Resilience and Personal Transformation.” If there is one myth I wish society would retire, it’s the idea that resilience means “toughness” or “bouncing back.”

Rethinking resilience based on research

Moments like Maria’s reveal something important: The way people tend to talk about resilience often doesn’t match how people actually live through adversity.

In popular culture, resilience is often equated with grit, toughness or relentless positivity. People celebrate the warrior, the fighter, the triumphant survivor.

But across research, clinical practice and lived experience, resilience is something far more nuanced, raw and human.

It’s not a personality trait that some people simply have and others lack. Decades of research show resilience is a dynamic process. It’s shaped by the small, everyday decisions and adjustments individuals make as they adapt to significant adversity while maintaining, or gradually regaining, their psychological and physical footing over time.

And importantly, resilience does not mean the absence of distress.

Research on people facing serious life disruptions shows that distress and resilience often coexist. For example, in my study of adolescent and young adult cancer survivors, participants reported being upset about finances, body image and disrupted life plans, while simultaneously highlighting positive changes, such as strengthened relationships and a greater sense of purpose.

Resilience, in other words, is not about erasing pain and suffering. It is about learning how to integrate difficult experiences into a life that continues forward.

How resilience really works

At one point, Maria told me she had started avoiding mirrors, intimacy, even conversations that made others uncomfortable.

“Well, you’re strong,” people would tell her. “Just stay positive. This too shall pass.”

But strength, she said, felt like a performance.

What ultimately shifted for Maria was not an increase in toughness. It was permission to grieve.

She began speaking openly about the loss of her breast; not just as a medical procedure but as a symbolic loss tied to identity, sexuality and womanhood. She joined a support group. She allowed herself to feel anger alongside gratitude for survival.

This kind of emotional processing turns out to be central to resilience.

My colleagues and I have found that people who actively process loss, rather than suppress it, demonstrate better long-term adjustment. Tamping down negative feelings may provide short-term relief, but over time it is associated with greater stress on your body and more difficulty adapting.

In other words, resilience is not about sealing the wound and pretending it no longer aches. It is about learning how to carry the wound without letting it consume your entire story.

Neuroscience supports this integration model. When people engage in meaning-making – reflecting on their experiences and incorporating them into a coherent life narrative – brain networks associated with emotional regulation and cognitive flexibility become more active. The brain, quite literally, reorganizes as you adapt to new realities.

Maria described the change simply.

“I don’t like what happened,” she told me. “But I’m not at war with my body anymore.”

That is resilience.

Practices that help build resilience

If resilience is about integration rather than toughness and bouncing back, how can you cultivate it? Research across psychology, neuroscience and chronic illness points to several evidence-based strategies:

  • Allow emotional complexity: Resilient people are not relentlessly positive. They allow space for the full range of emotions, such as gratitude and grief, hope and fear. Paying attention to your feelings through strategies such as reflective writing or psychotherapy have been linked to improved psychological adaptation.

  • Build a coherent narrative: Human beings are storytellers. Trauma can shatter one’s sense of self, but constructing a narrative that acknowledges loss while identifying continuity and growth supports adaptation. The goal is not to spin suffering into silver linings, but to situate it within a broader life story. For example, someone might say, “Cancer derailed my plans and changed my body, but it also clarified what matters to me and how I want to move forward.”

  • Lean into connection: Isolation magnifies suffering. Social support is one of the strongest predictors of how well people are able to cope and move forward after illness or trauma. For Maria, connection with other women who had had mastectomies normalized her experience and reduced shame.

  • Practice deliberate pauses: Intentionally give yourself some time to breathe. Mindfulness and contemplative solitude can strengthen your ability to regulate emotions and recover from stress. Pausing allows experience to be processed rather than avoided.

  • Expand identity: Illness, loss and trauma reshape how you think of yourself. Rather than clinging to who you were, resilience often involves expanding who you are becoming. Research on post-traumatic growth shows that people often report deeper relationships, clarified priorities and renewed purpose – not because trauma was good, but because it forced reevaluation. Maria no longer describes herself simply as a breast cancer patient. She is a survivor, yes, but also an advocate, a mentor, a woman whose sense of femininity is self-defined rather than dictated by her anatomy.

Moving forward

We are living in a time of widespread burnout and rising mental health challenges, where cultural pressure to appear strong often leaves people silently struggling. An insistence on grit and relentless optimism can backfire, making people feel inadequate when they inevitably feel pain.

Resilience is not about returning to who you were before illness, loss or trauma. It is about becoming someone new: someone who carries the scar, remembers the loss and still chooses to engage with life.

Maria still pauses when she sees her reflection. But she no longer turns away.

“This is my body,” she told me recently. “This is my story.”

Resilience is not forged in the denial of vulnerability, but in its acceptance. Not in bouncing back, but in integrating what has happened into who you are becoming.

And that, I believe, is where real strength lives.

25 million people lost Medicaid after the COVID-19 pandemic — and state policies shaped who stayed covered

Source: The Conversation – USA (3) – By Aparna Soni, Associate Professor of Health Policy and Management, Indiana University

Medicaid enrollment surged during the COVID-19 pandemic. SDI Productions/E+ via Getty Images

During the COVID-19 pandemic, the number of people covered by Medicaid rose month after month – an unusual pattern for the government’s
insurance program for people with low incomes and disabilities.

Why? A policy of continuous coverage during the pandemic essentially halted Medicaid disenrollment to make it easier for people to stay insured during the public health emergency. By early 2023, enrollment had reached an all-time high of more than 94 million people.

Then the trend abruptly reversed.

Between April 2023 – when states began resuming eligibility checks that had been paused during the pandemic – and mid-2025, more than 25 million people were disenrolled from Medicaid. The process became known as the “Great Unwinding.”

As a health economist who studies the effects of public policy on insurance coverage and health outcomes, I’ve been following these enrollment shifts closely. Now that the unwinding has mostly played out, Medicaid enrollment data reveal a fragmented, state-by-state picture. Coverage losses were not evenly distributed, reflecting differences in how states carried out eligibility checks and how much administrative burden they placed on eligible people trying to stay enrolled.

That patchwork of state policies still matters now. Under the 2025 budget law, widely referred to as the One Big Beautiful Bill Act, as of Jan. 1, 2027, states will have to enforce new Medicaid work rules and more frequently check eligibility for many adults who gained coverage during the expansion. So the same administrative differences exposed by the rollback of Medicaid coverage after the pandemic are likely to play a role again in who keeps their coverage and who loses it.

Pandemic enrollment jump

Before the pandemic, Medicaid and the Children’s Health Insurance Program, which provides coverage for children in families with modest incomes, together covered about 71 million Americans.

At its peak in 2023, during the COVID-19 pandemic, Medicaid enrollment reached more than 94 million people.

Normally, people must regularly renew their eligibility for these programs by confirming their income and household information. States remove people who no longer qualify or who fail to complete paperwork.

During the pandemic, however, those routine disenrollments largely stopped as part of the March 2020 Families First Coronavirus Response Act, which included a provision requiring states to keep most people continuously enrolled in Medicaid in exchange for additional federal funding. At the same time, job losses and income declines made more Americans eligible for Medicaid.

Together, those factors caused Medicaid enrollment to surge. Enrollment increased by roughly 23 million people during the COVID-19 pandemic, reaching about 94.1 million by 2023.

While the national uninsured rate fell to a record low of 8% during the pandemic, the increase in Medicaid enrollment did not translate one-for-one into fewer uninsured people. Some of those who gained Medicaid coverage had previously been insured through employer-sponsored plans, reflecting shifts in coverage as well as new coverage gains.

The ‘Great Unwinding’

The pandemic era’s continuous coverage policy was always meant to be temporary. Congress ended it in late 2022, allowing states to restart eligibility reviews beginning April 1, 2023.

That process required tens of millions of people to confirm they were still eligible or else lose their Medicaid coverage.

By the time most states finished the process, more than 25 million people had been disenrolled, while about 56 million had their coverage renewed.

One striking feature of the unwinding is that the majority – 69% of people who lost coverage – did so not because they were formally determined to be ineligible but because of administrative reasons, such as failure to return renewal forms or outdated contact information. These are known as “procedural disenrollments.”

Administrative hurdles during the unwinding disrupted continuity of coverage and, in turn, access to care. Racial and ethnic minorities and those with greater health needs were most affected.

State policy shapes coverage losses

As the number of people covered by Medicaid plunged, many states adopted policies to reduce unnecessary coverage loss. These administrative choices ultimately influenced how many eligible people remained covered.

The most common and most effective administrative tool was ex parte – or automatic – renewals. Instead of requiring beneficiaries to submit paperwork, states used existing government data such as tax records or participation in other assistance programs to automatically verify eligibility.

Six months into the unwinding process, more than half of Medicaid renewals were being completed automatically. States that relied more heavily on ex parte renewals had lower disenrollment rates.

States also experimented with other approaches, including extending deadlines for renewal paperwork, adding more staff to answer phones and help people complete renewals, and running outreach campaigns reminding people to update contact information.

Where Medicaid enrollment stands now

The most recent data shows that Medicaid enrollment has largely stabilized after several years of dramatic change. As of December 2025, the most recent month for which data is available, total enrollment stands at roughly 76 million – above prepandemic levels of about 71 million but below the pandemic peak of 94.1 million.

The unwinding offers a clear picture of how Medicaid functions when its rules change. During the pandemic, continuous coverage policies largely eliminated the usual cycle of people moving in and out of the program. When those policies ended, that churn returned – often driven not by changes in eligibility but by how renewal processes were implemented.

Looking ahead, the same state-by-state differences in policies that helped or hindered people’s ability to maintain Medicaid enrollment as pandemic coverage wound down are likely to matter again. Under the 2025 budget law, states must begin checking eligibility for many adults every six months instead of once a year. States must also enforce new work requirements for many adults starting in 2027.

The law also delayed some federal changes that were supposed to make Medicaid enrollment and renewal easier. So even when the rules come from Washington, who keeps their coverage may still depend heavily on how much paperwork, automation and hands-on help each state builds into the process.

Together, these trends suggest that future enrollment levels will be shaped by both expanding and constraining forces. These forces will have real consequences for the millions of people who rely on Medicaid – not just for coverage, but for consistent access to care, medications and financial protection during periods of instability.

The enduring legacy of medieval Christian depictions of Islam in today’s political discourse

The war with Iran is not just a geopolitical conflict. We see religious rhetoric used to cast strategic interests as a moral or sacred matter.

U.S. House Speaker Mike Johnson described Iran’s majority faith tradition, Shiite Islam, as a “misguided religion” while discussing the ongoing U.S. strikes against Iran on March 4, 2026. A complaint made to the Military Religious Freedom Foundation alleged that same month that an unnamed military commander had said that “President Trump has been anointed by Jesus to light the signal fire in Iran to cause Armageddon and mark his return to Earth.” In the Book of Revelation, Armageddon represents the final battle between good and evil, associated with the second coming of Jesus Christ.

Soon after the U.S. attack on Iran, right-wing pastor Andrew Sedra commented that “Trump is going after the head of the snake, which is Islam.” He added that “God is using President Trump in a prophetic moment of time to execute judgment on evil and wicked civilizations.”

In part, such religious rhetoric draws on older narratives about Islam in Christian thought. In medieval times, Islam was often portrayed as a violent and extremist faith. Over the past few decades, many American politicians and Christian clergy have disparaged Islam and its believers. My research shows that these earlier portrayals remain recognizable in the rhetoric today.

Hostile depictions

Early Christian theologians began to designate Islam as a theological rival soon after its emergence in 610 C.E. In the eighth century, the monk John of Damascus described Islam as a “heresy” in his work “The ‘Heresy of the Ishmaelites.’” This is widely considered the earliest documented critique of Islamic doctrine.

In his 2002 book, “Saracens: Islam in the Medieval European Imagination,” historian John Tolan writes that medieval Christian writers disseminated “crude insults to the Prophet, gross caricatures of Muslim ritual [and] deliberate deformation of passages of the Koran.” They portrayed Muslims as “libidinous, gluttonous semi-human barbarians,” he adds.

Tolan and other historians show how these hostile depictions developed in time in monasteries and royal courts. In popular culture, epic poems called “chansons de geste” glorified Christian heroes vanquishing Muslim foes.

Notably, medieval Muslim theologians also produced cutting critiques of Christian doctrines such as the Trinity, which they viewed as polytheistic. However, these writings circulated largely within scholarly circles. In Christian Europe, however, anti-Muslim writings were often used to justify the Crusades. Pope Urban II urged in 1095 that Holy Land be wrested from those who inhabited it and brought under Christian control.

Similarly, the Second, Third and Fourth Crusades were preceded by papal letters that depicted Muslims as enemies of the faith and called on Christians to reclaim Palestine.

The eventual military failure of the Crusades posed a new theological problem to Christian thinkers.

Medieval Christians believed history reflected God’s judgment. As a result, they struggled to explain the military success of Muslim armies in theological terms, since such victories in the Holy Land would imply divine favor for Muslims. In order to reconcile this, some medieval Christians developed the idea that the defeats were a punishment for Christian sin.

Accordingly, medieval epic poems and art often depicted Muslims as near-demonic, bloodthirsty figures wearing turbans and strange robes.

Christian missionary narratives

In later centuries, these anti-Muslim depictions were reworked to justify colonialism. Scholar Edward Said famously critiqued early modern narratives about people and cultures from the Middle East and Arab world in his foundational 1978 work, “Orientalism.”

He argued that Orientalist stereotypes reduced diverse peoples to a set of mostly negative traits: barbaric, violent, incomprehensible, but also lazy, gullible and mysterious. While not held by all Christians, these ideas circulated broadly within Christian and Western intellectual traditions, shaping durable representations of Muslims in literature, art, theology and politics.

Scholar Deepa Kumar, who recognized this tension, wrote that “while ordinary people can and do resist dominant ideas, those who rule the society tend to set the terms of discussion.”

Anti-Muslim tropes were reflected in Christian missionary narratives. In the 19th century, figures such as David Livingstone promoted what later came to be known as the “three C’s” of colonial expansion: Christianity, commerce and civilization, all portrayed as benefiting the colonized peoples.

Over time, these ideas became part of a broader moral justification for European imperial expansion, framing colonial rule as a civilizing mission. As part of this effort, missionaries often contrasted the moral authority of Christianity with Islam, which they portrayed as a morally stagnant and simplistic.

Islamophobia today

While these hostile themes have been adapted over centuries to fit new contexts, they are recognizable in political and media rhetoric today. This rhetoric shapes popular understandings of Islam in troubling ways.

In a survey of American Baptist clergy conducted for my 2026 book, “Confronting Islamophobia in the Church,” with co-author and Baptist pastor Michael Woolf, I found that many pastors describe Islam and Muslims as inherently violent, blasphemous, oppressive toward women, or incompatible with Western society. These pastors have adapted old Christian tropes to contemporary moral language. Theological accusations of Islamic “heresy” have morphed into concerns about apparent Muslim violence and women’s oppression.

A 2019 study found that 9 in 10 pastors believe that they influence what their congregants think about social issues, suggesting that religious prejudice, including Islamophobia, can be reinforced in church contexts. Indeed, historians of American evangelicalism such as Kristin Kobez du Mez note that Islam has been often portrayed in evangelical church contexts as violent and opposed to Christian values. In her 2020 bestselling book, “Jesus and John Wayne,” she cites a 2002 poll that found that 77% of evangelical leaders held an overall unfavorable view of Islam, and 70% agreed that Islam was “a religion of violence.”

At the same time, Muslim groups like Council on American-Islamic Relations and national interfaith coalitions such as Shoulder to Shoulder Campaign have worked with Christians to challenge these portrayals and promote more nuanced understandings of Islam. For example, Shoulder to Shoulder Campaign delivers anti-Islamophobia training to pastors and congregations – Faith over Fear – around the country.

Researchers have linked incendiary rhetoric about Muslims to spikes in discrimination and hate crimes in Europe and North America. A study by the Center for the Study of Organized Hate found a significant surge in anti-Muslim hate speech in the first week of the war in Iran. When politicians describe Islam as the enemy and the West as a civilizing force, they risk turning distant wars into everyday hostility toward American Muslim communities.

Does ‘federated unlearning’ in AI improve data privacy, or create a new cybersecurity risk?

Source: The Conversation – Canada – By Abbas Yazdinejad, Assistant Professor, Department of Computer Science, University of Regina

As the capacity of artificial intelligence (AI) increases at an exponential rate, so do concerns about the privacy of user data.

Increasingly, organizations around the world are adopting something called federated unlearning that enables AI training without centralizing sensitive data. This allows hospitals, banks and government agencies to collaborate while keeping data local — an approach that’s regarded as a major advance in privacy.

Federated unlearning promises that user data can be removed from a trained AI system. A hospital, for example, could ask its AI system to forget a patient’s data.

In the European Union, this is defined as the “right to be forgotten.” Similar data deletion rights exist globally, though with different legal strengths and technical interpretations.

But what if the request to forget is not itself trustworthy? Our research shows that while federated unlearning appears to be a natural extension of data rights, it also introduces new hidden security risks that undermine trust in our digital world.

Silent cyber threats: How shadow AI could undermine Canada’s digital health defences


New stealth vulnerabilities

During a process of federated unlearning, participants train local models on personal data, then send updates for those models to a central server. The server aggregates these updates to learn a single, shared system, which allows models to benefit from both the scale and scope of data.

Researchers already know these federated systems can become affected by data poisoning attacks where attackers bias the data they use to train their local model to alter the shared model’s performance.

Poisoning attacks can create stealth vulnerabilities, also known as “backdoors,” that only activate under specific conditions.

Federated unlearning introduces a new and subtle dimension to this threat.

An attacker could first inject harmful patterns into the model. Later, they could submit a request to remove their data. If the unlearning process is imperfect — as many current methods are — the visible traces of the attack may disappear, while the hidden effects remain.

A new security blind spot

This issue creates a new kind of cross-sectoral national security vulnerability that is easy to overlook.

In one hypothetical scenario, repeated unlearning requests could gradually degrade a model’s performance — a slow, hard-to-detect disruption. Unlike traditional cyberattacks, this would not cause the immediate failure of a model, but would erode its reliability over time.

In another case, carefully timed data removal could bias outcomes. A financial risk model, for instance, could be subtly shifted by removing certain data contributions at key moments.

These risks are amplified by the very nature of federated systems. Because data remains distributed, there is often limited visibility into how individual contributions affect the final model.

What emerges is a security blind spot — a mechanism designed to enhance privacy that may also weaken system integrity.

Why current solutions fall short

Many federated unlearning techniques are designed with efficiency in mind. Instead of retraining a model from scratch — which can be costly — the techniques attempt to approximate the removal of data influence. While practical, this approach has limits.

Emerging evidence shows that machine learning models can retain complex patterns even after attempts to remove data and, in adversarial settings, harmful effects may persist even after “unlearning.”

At the same time, there are few safeguards to verify whether an unlearning request itself is legitimate. This gap is not only technical, but also structural, and can lead to multiple security vulnerabilities.

Unlearning is a security problem

Federated unlearning is often framed as a privacy feature. This framing is incomplete. In practice, removing data from a model changes its behaviour — sometimes in unpredictable ways. This makes unlearning a security-sensitive operation, and not just a data management tool.

Like other critical system actions, federated unlearning should be subject to verification, auditing and monitoring. These additional actions could include:

  • Validating the origin of unlearning requests.
  • Tracking how model behaviour changes after data removal.
  • Detecting repeat or suspicious requests.
  • Designing methods that ensure complete removal of harmful influence.

A critical moment for AI governance

AI systems are increasingly used in decisions affecting people’s lives — from medical diagnoses to financial approvals. Here, privacy and reliability both matter.

Federated unlearning sits at this intersection. It aims to protect data rights, but may introduce risks not widely understood. If ignored, systems which are designed to enhance trust could become undermined.

Canada is at an important juncture in shaping how AI systems are governed. Policies around data deletion, accountability and transparency are evolving rapidly.

Federated unlearning will likely become part of this landscape. As it’s adopted, it must be treated with the same level of scrutiny as other security-critical mechanisms.

The challenge is no longer to just make AI forget data. It is to ensure that, in the process of forgetting, we are not allowing something more dangerous to remain.

La conversación docente: las escuelas de 0 a 3 años como inversión de futuro

A los ocho meses de tener a mi primera hija, después de alargar la baja de maternidad al máximo y añadirle los meses de excedencia que me fueron posibles, llegó el momento de llevarla a una guardería. Todavía recuerdo lo importante que fue para mi tranquilidad mental el momento de conocer a su cuidadora. La dulzura y empatía que me transmitió Rosa transformaron completamente ese momento angustioso de dejar a mi bebé en manos de una persona extraña. De pronto, supe que estaría bien cuidada y se sentiría querida durante esas horas.

La influencia de las maestras y cuidadoras de infantil (la mayoría son mujeres), especialmente en la etapa de 0 a 3 años, es difícilmente exagerable. Y va mucho más allá de permitir a las familias conciliar con tranquilidad y garantías. En esta etapa inicial de la vida, tener una buena atención en la escuela es tan determinante para el rendimiento escolar posterior que se considera uno de los principales contribuyentes a la equidad educativa.

Por eso es tan necesario que la cobertura pública y la oferta de plazas no se convierta en un artículo de oferta electoral de quita y pon: los proyectos, la financiación y los equipos necesitan un apoyo y compromiso permanentes de las instituciones. Como explica Estefanía Hita, de la Universidad Internacional de La Rioja, para este objetivo ayuda pensar en esta etapa educativa no en términos de gastos presupuestarios, sino de inversión de futuro.

Especialmente para los niños y niñas en situaciones más vulnerables. Actuar pronto es más eficaz, mientras que corregir desigualdades cuando ya están consolidadas resulta más difícil y costoso. Es la razón del potencial de esta etapa como ascensor social.

“España tiene una alta tasa de escolarización en la etapa de 0 a 3 años, con un 41,8 % de niños escolarizados, por encima de la media de la OCDE. Pero escolarizar no es lo mismo que garantizar igualdad de oportunidades. Lo importante no es solo cuántos niños asisten, sino en qué condiciones lo hacen”, nos explica esta experta. El precio, los horarios, la estabilidad de los centros o la calidad de los proyectos cambian mucho según el lugar. Estas diferencias aparecen incluso antes de que los niños empiecen a hablar, y tienen consecuencias reales en su desarrollo.

Desde que mi hija, mi marido y yo conocimos a Rosa en aquella guardería de Madrid, la formación y la investigación en esta etapa del desarrollo infantil han evolucionado mucho. En The Conversation hemos hablado de cómo el papel de los especialistas en la etapa de 0 a 3 años es cada vez más profesional y especializado. Su acompañamiento experto permite a los niños explorar y desarrollarse cognitiva y motrizmente de manera satisfactoria, sin por supuesto olvidar su rol fundamental como referencia afectiva e incluso corporal.

Todos estos avances influye en cómo la sociedad percibe a estos profesionales y cómo su imprescindible labor es categorizada, protegida y retribuida. Está demostrado que ir a la escuela infantil es positivo para el desarrollo mental, físico y social. Y la escuela infantil solamente puede tener este papel beneficioso cuando está compuesta de profesionales bien formados y justamente reconocidos.
