Rétention des mineurs à Mayotte : la loi qui inquiète juristes et associations

Source: The Conversation – France in French (3) – By Florian Aumond, Maître de conférences en droit public, Université de Poitiers

Le 10 juillet dernier, la loi de programmation pour la refondation de Mayotte a été définitivement adoptée par le Sénat. Si ce texte comprend un volet social, l’un de ses articles organise la création de lieux où pourront être enfermés des mineurs étrangers. Une pratique pourtant en principe interdite par le droit français.


Adopté définitivement par le Sénat le jeudi 10 juillet 2025, le projet de loi de programmation pour la refondation de Mayotte s’inscrit dans le processus législatif engagé à la suite des dommages causés par le cyclone Chido, qui avait ravagé l’île dans la nuit du 13 au 14 décembre 2024. Ce nouveau texte affirme « l’ambition de la France pour le développement de Mayotte », à travers une série de mesures structurelles.

La loi couvre des domaines variés, comme l’encadrement de l’habitat illégal, la convergence accélérée vers le droit commun des prestations sociales, ou encore la modification du mode de scrutin applicable à Mayotte. Mais ce texte approfondit également la dérogation au droit commun en matière d’immigration, inscrit dans le Code de l’entrée et du séjour des étrangers et du droit d’asile (Ceseda) – pourtant en vigueur à Mayotte depuis 2014.

Le titre II de la loi, intitulé « Lutter contre l’immigration clandestine et l’habitat illégal », introduit ainsi une série de dispositions qui durcissent substantiellement les conditions de séjour des personnes étrangères à Mayotte. Deux titres de séjour « vie privée et familiale » se voient fortement limités : ils étaient jusqu’ici perçus comme permettant la régularisation d’un trop grand nombre d’étrangers. Désormais, l’accès à ces titres de séjour sera soumis à la condition d’être entré régulièrement sur le territoire et à une résidence à Mayotte depuis au moins sept ans pour les titres délivrés en raison des « liens personnels et familiaux ».

Le texte prévoit en outre des dispositions relatives à la lutte contre les reconnaissances frauduleuses de paternité et de maternité, ainsi qu’un chapitre sur la lutte contre l’immigration irrégulière. C’est au sein de ce dernier que se trouve une disposition significative de cette loi. Inscrite à l’article 14, elle porte sur la création de lieux de rétention « spécialement adaptés à la prise en charge des besoins de l’unité familiale ».

À l’instar des autres dispositions relatives aux droits des étrangers, la perspective de création de nouveaux centres de rétention « familiaux » a suscité de vives critiques dès la présentation du projet de loi. De nombreuses voix, notamment associatives, ont souligné la violation par cette mesure du principe d’intérêt supérieur de l’enfant. Il s’agit pourtant d’un pilier du régime juridique de protection des droits de l’enfant, depuis sa consécration par la Convention internationale sur le sujet, en 1989.

Pour Unicef France,

« la création prévue d’unités familiales […] ne (fait) que perpétuer une logique d’enfermement des familles avec enfants, alors que la fin de l’enfermement administratif des enfants était initialement prévue en 2027. »

La « zone d’attente », une fiction juridique qui permet l’enfermement des mineurs

Pour comprendre la réaction d’Unicef France, il convient de rappeler le cadre juridique actuel en matière de privation de liberté des personnes étrangères.

Le droit français distingue deux régimes : la rétention administrative concerne les étrangers déjà présents sur le territoire français et permet à l’administration d’exécuter une décision d’éloignement ; la « zone d’attente », quant à elle, ne s’applique qu’aux étrangers non admis sur le territoire français, arrivés par voie ferroviaire, maritime ou aérienne.

Cette « zone d’attente » s’apparente à une fiction juridique. Elle permet en effet de considérer qu’un étranger physiquement sur le territoire français n’y est pas juridiquement présent. Une telle fiction comporte des conséquences majeures pour les mineurs étrangers, car s’il n’est pas possible d’édicter une mesure d’éloignement à leur encontre. Il est en revanche tout à fait autorisé de leur interdire l’entrée sur le territoire, les contraignant ainsi à retourner dans leur pays d’origine ou dans le dernier pays par lequel ils ont transité.

Les zones d’attente sont donc des sas permettant de mettre en œuvre ces mesures. Celles-ci sont non seulement susceptibles de concerner les mineurs accompagnants – souhaitant entrer en France avec leur famille ou un adulte référent –, mais également les mineurs non accompagnés.

La loi n°2024-42 du 26 janvier 2024 pour contrôler l’immigration, améliorer l’intégration a enregistré une avancée significative par rapport à cette situation en consacrant l’interdiction générale de placer les mineurs en rétention, y compris lorsqu’ils accompagnent un adulte. L’article L.741-5 du Ceseda, inséré par la loi de janvier 2024, dispose désormais expressément que

« l’étranger mineur de 18 ans ne peut faire l’objet d’une décision de placement en rétention ».

Toutefois, l’entrée en vigueur de cette disposition a été repoussée pour Mayotte au 1er janvier 2027 en raison, selon le ministre de l’intérieur, « des spécificités de ce territoire – les mineurs rest(ant) moins de quarante-huit heures en moyenne dans le centre de rétention administrative de Mayotte, voire moins d’une journée » et, plus généralement, en raison des « difficultés particulières qui se posent sur ce territoire ».

La première justification ne convainc guère, si l’on constate que la durée de maintien en rétention n’est pas spécifiquement courte à Mayotte : elle est même souvent moindre dans l’Hexagone. Pour ce qui est des conditions spécifiques à Mayotte, s’il est indéniable que l’île connaît un contexte migratoire particulier, rien ne permet d’assurer que déroger au droit commun en enfermant des mineurs en migration y apportera une quelconque solution.

La France a déjà été condamnée pour l’enfermement de mineurs par la justice européenne

C’est dans ce contexte que s’inscrit l’article 14 de la loi de programmation pour la refondation de Mayotte. Il déroge à l’interdiction de placer en rétention un étranger mineur en introduisant de nouveaux lieux : des unités familiales « spécialement aménagées et adaptées », qui devront garantir « aux membres de la famille une intimité adéquate, dans des conditions qui tiennent compte de l’intérêt supérieur de l’enfant ».

Le gouvernement justifie la mesure par le fait qu’elle permettrait de « maintenir les capacités opérationnelles d’éloignement de ce public », c’est-à-dire les familles avec enfants.

Malgré les précautions terminologiques, ces « unités familiales » constituent bien des lieux de rétention administrative, ainsi qu’il ressort expressément de l’exposé des motifs de la loi, dans lequel le ministre des outre-mer évoque « une [unité familiale pour la rétention des mineurs] ». Leur création va donc à rebours des engagements pris par le gouvernement dans la loi de janvier 2024, qui en consacrait une interdiction générale. Ces engagements visaient à aligner le droit français avec la jurisprudence de la Cour européenne des droits de l’homme (CEDH), laquelle a déjà condamné à 11 reprises la France pour des situations de privation de liberté de mineurs en migration.

Le gouvernement a pris des mesures pour éviter que ce texte ne lui vaille de nouvelles condamnations par la CEDH. À la suite de l’avis du Conseil d’État relatif au projet de loi, il a été précisé que le placement en rétention des mineurs ne pouvait excéder une durée de 48 heures. Il est en effet connu que la CEDH retient la durée de la rétention parmi les critères pris en compte afin de conclure à la violation de l’article 3 de la Convention européenne des droits de l’homme, relatif à l’interdiction de la torture et des peines et traitements inhumains ou dégradants.

Elle s’appuie cependant également sur l’âge des personnes enfermées, et les conditions du maintien en centre de rétention administrative (CRA), où sont retenues les personnes migrantes en situation irrégulière. Or, dans un rapport remis en 2023, le contrôleur général des lieux de privation de liberté dénonçait les conditions qui prévalent dans le CRA de Mayotte – situé à Pamandzi –, notamment les difficultés d’accès à l’eau, le maintien des lumières allumées toute la nuit, l’état et l’insuffisance des sanitaires ou l’impossibilité de changer de vêtements.

Une mesure en contradiction avec toutes les recommandations des associations et des organisations internationales

La création de ces nouveaux lieux d’enfermement entre, par ailleurs, en totale contradiction avec les avis de différentes institutions et autorités indépendantes, comme le défenseur des droits, la commission nationale consultative des droits de l’homme, ou encore le contrôleur général des lieux de privation de liberté, toutes ayant rappelé que la rétention – même temporaire et aménagée – compromet le développement psychique et affectif de l’enfant.

Le défenseur des droits a ainsi mis en avant que « la place d’un enfant n’est pas dans un lieu d’enfermement, fût-il conçu pour accueillir des familles ».

La France va également à l’encontre des recommandations du Comité des droits de l’homme des Nations unies, qui l’a appelée à réexaminer les régimes dérogatoires en matière d’immigration dans les territoires ultramarins et à « accélérer l’extension de l’interdiction de la rétention administrative des mineurs à Mayotte ».

Saisi le 16 juillet 2025 par le premier ministre et plus de soixante députés, le Conseil constitutionnel devra se prononcer dans un délai d’un mois sur la conformité de ces dispositions avec les droits fondamentaux garantis par la Constitution.

How states are placing guardrails around AI in the absence of strong federal regulation

U.S. state legislatures are where the action is for placing guardrails around artificial intelligence technologies, given the lack of meaningful federal regulation. The resounding defeat in Congress of a proposed moratorium on state-level AI regulation means states are free to continue filling the gap.

Several states have already enacted legislation around the use of AI. All 50 states have introduced various AI-related legislation in 2025.

Four aspects of AI in particular stand out from a regulatory perspective: government use of AI, AI in health care, facial recognition and generative AI.

Government use of AI

The oversight and responsible use of AI are especially critical in the public sector. Predictive AI – AI that performs statistical analysis to make forecasts – has transformed many governmental functions, from determining social services eligibility to making recommendations on criminal justice sentencing and parole.

But the widespread use of algorithmic decision-making could have major hidden costs. Potential algorithmic harms posed by AI systems used for government services include racial and gender biases.

Recognizing the potential for algorithmic harms, state legislatures have introduced bills focused on public sector use of AI, with emphasis on transparency, consumer protections and recognizing risks of AI deployment.

Several states have required AI developers to disclose risks posed by their systems. The Colorado Artificial Intelligence Act includes transparency and disclosure requirements for developers of AI systems involved in making consequential decisions, as well as for those who deploy them.

Montana’s new “Right to Compute” law sets requirements that AI developers adopt risk management frameworks – methods for addressing security and privacy in the development process – for AI systems involved in critical infrastructure. Some states have established bodies that provide oversight and regulatory authority, such as those specified in New York’s SB 8755 bill.

AI in health care

In the first half of 2025, 34 states introduced over 250 AI-related health bills. The bills generally fall into four categories: disclosure requirements, consumer protection, insurers’ use of AI and clinicians’ use of AI.

Bills about transparency define requirements for information that AI system developers and organizations that deploy the systems disclose.

Consumer protection bills aim to keep AI systems from unfairly discriminating against some people, and ensure that users of the systems have a way to contest decisions made using the technology.

Bills covering insurers provide oversight of the payers’ use of AI to make decisions about health care approvals and payments. And bills about clinical uses of AI regulate use of the technology in diagnosing and treating patients.

Facial recognition and surveillance

In the U.S., a long-standing legal doctrine that applies to privacy protection issues, including facial surveillance, is to protect individual autonomy against interference from the government. In this context, facial recognition technologies pose significant privacy challenges as well as risks from potential biases.

Facial recognition software, commonly used in predictive policing and national security, has exhibited biases against people of color and consequently is often considered a threat to civil liberties. A pathbreaking study by computer scientists Joy Buolamwini and Timnit Gebru found that facial recognition software poses significant challenges for Black people and other historically disadvantaged minorities. Facial recognition software was less likely to correctly identify darker faces.

Bias also creeps into the data used to train these algorithms, for example when the composition of teams that guide the development of such facial recognition software lack diversity.

By the end of 2024, 15 states in the U.S. had enacted laws to limit the potential harms from facial recognition. Some elements of state-level regulations are requirements on vendors to publish bias test reports and data management practices, as well as the need for human review in the use of these technologies.

Generative AI and foundation models

The widespread use of generative AI has also prompted concerns from lawmakers in many states. Utah’s Artificial Intelligence Policy Act requires individuals and organizations to clearly disclose when they’re using generative AI systems to interact with someone when that person asks if AI is being used, though the legislature subsequently narrowed the scope to interactions that could involve dispensing advice or collecting sensitive information.

Last year, California passed AB 2013, a generative AI law that requires developers to post information on their websites about the data used to train their AI systems, including foundation models. Foundation models are any AI model that is trained on extremely large datasets and that can be adapted to a wide range of tasks without additional training.

AI developers have typically not been forthcoming about the training data they use. Such legislation could help copyright owners of content used in training AI overcome the lack of transparency.

Trying to fill the gap

In the absence of a comprehensive federal legislative framework, states have tried to address the gap by moving forward with their own legislative efforts. While such a patchwork of laws may complicate AI developers’ compliance efforts, I believe that states can provide important and needed oversight on privacy, civil rights and consumer protections.

Meanwhile, the Trump administration announced its AI Action Plan on July 23, 2025. The plan says “The Federal government should not allow AI-related Federal funding to be directed toward states with burdensome AI regulations … ”

The move could hinder state efforts to regulate AI if states have to weigh regulations that might run afoul of the administration’s definition of burdensome against needed federal funding for AI.

Philadelphia is using AI-driven cameras to keep bus lanes clear – transparency can help build trust in the system

Source: The Conversation – USA – By Murugan Anandarajan, Professor of Decision Sciences and Management Information Systems, Drexel University

The Southeastern Pennsylvania Transportation Authority piloted a new enforcement tool in Philadelphia in 2023: AI-powered cameras mounted on seven of its buses. The results were immediate and dramatic: In just 70 days, the cameras flagged over 36,000 cars blocking bus lanes.

The results of the pilot gave the transportation authority, also called SEPTA, valuable data into bus route obstruction and insights into the role of technology to combat these problems.

In May 2025, SEPTA and the Philadelphia Parking Authority officially launched the program citywide. More than 150 buses and 38 trolleys across the city are fitted with similar artificial intelligence systems that scan license plates for possible violations. The system uses AI-powered cameras that use computer vision technology to spot vehicles blocking bus lanes and scans license plates to identify the vehicles breaking the rules. If the system flags a possible infraction, a human reviewer confirms it before a fine is issued: US$76 in Center City, $51 elsewhere.

This rollout comes as SEPTA faces a $213 million budget shortfall, with imminent service cuts and fare hikes.

I’m a professor of information systems and the academic director of LeBow College of Business’s Center for Applied AI and Business Analytics at Drexel University. The center’s research focuses on how organizations use AI, and what that means for trust, fairness and accountability.

In a recent survey the center conducted with 454 business leaders from industries including technology, finance, health care, manufacturing and government, we found that the use of AI is often rolled out faster than the governance needed to make sure it works fairly and transparently.

That gap between efficiency and oversight is especially common in public-sector organizations, according to our survey.

That’s why I believe it’s important for SEPTA to manage its AI enforcement system carefully to earn public trust, while minimizing risks.

Fairness and transparency

When cars block a bus lane, they clog traffic. The resulting delays can mess up a person’s day, causing missed connections or making riders late for work. That can leave riders with the feeling they can’t rely on the transit system.

So, if AI enforcement helps keep those lanes clear, it’s a win. Buses move faster, and commutes are quicker.

But here’s the issue: Good intentions don’t work if the system feels unfair or untrustworthy. Our survey also found that more than 70% of the surveyed organizations don’t fully trust their own data. In the context of public enforcement, whether it’s transit agencies or parking authorities, that’s a warning sign.

Without trustworthy data, AI-powered ticketing can turn efficiency into costly mistakes, such as wrongly issued citations that must be refunded, lost staff time correcting errors, and even legal challenges. Public confidence matters here because people are most likely to follow the rules and accept penalties when they see the process as accurate and transparent.

Furthermore, this finding from our survey really caught my attention: Only 28% of organizations report having a well-established AI governance model in place. Governance models are the guardrails that keep AI systems trustworthy and aligned with human values.

That’s troubling enough when private companies are using AI. But when a public agency like SEPTA looks at a driver’s license plate and sends the driver a ticket, the stakes are higher. Public enforcement carries legal authority and demands a higher level of fairness and transparency.

The AI label effect

One may ask, “Isn’t this ticketing system just like red-light or speed cameras?”

Technically, yes. The system detects rule-breaking, and a human reviews the evidence before a citation is issued.

But simply labeling the technology as AI can transform how it’s perceived. This is known as the framing effect.

Just calling something AI-driven can make people trust it less. Research has shown, whether a system is grading papers or hiring workers, that the exact same process draws more skepticism when AI is mentioned than when it isn’t. People hear “AI” and assume the machine is making judgment calls, so they start looking for flaws. Even if they think that AI is accurate, the trust gap never closes.

That perception means public agencies need to align AI-based enforcement with transparency, visible safeguards and easy ways to challenge mistakes. These measures increase trust in AI-based enforcement.

We’ve seen what can go wrong, and how quickly trust can erode, when an AI-based enforcement system malfunctions. In late 2024, AI cameras on Metropolitan Transportation Authority buses in New York City wrongly issued thousands of parking tickets, including nearly 900 cases where the drivers had actually followed the rules and parked legally.

Even if such errors are rare, they can damage public confidence in the system.

Build trust into the system

The Organization for Economic Cooperation and Development, the international body setting AI policy standards across dozens of countries, has found that people are most likely to accept AI-driven decisions when they understand how those decisions are made and have a clear, accessible way to challenge mistakes.

In short, AI enforcement tools should work for people, not just on them. For SEPTA, that could mean the following:

–Publishing clear bus-lane rules and any exceptions, so people know what’s allowed.

–Explaining safeguards, like the fact that every bus-camera violation is reviewed by Philadelphia Parking Authority staff before a ticket is issued.

–Offering a straightforward appeals process with management review and a right to appeal.

–Sharing enforcement data, such as how many violations and appeals are processed.

These steps signal that the system is fair and accountable, helping shift it from feeling like a ticketing machine into a public service that people can trust.

Iron nanoparticles can help treat contaminated water – our team of scientists created them out of expired supplements

Source: The Conversation – USA – By Ahmed Ibrahim Yunus, Ph.D. Candidate in Environmental Engineering, Georgia Institute of Technology

Today, approximately 1,800,000 acres of land in the United States is used for landfill waste disposal. In terms of volume, the U.S alone generated over 290 million tons of solid waste in 2018, an amount equivalent to about 235,000 Olympic-size swimming pools, assuming an average solid waste density of a half ton per cubic meter.

Roughly 9% – about 26 million tons – of this waste is made up of iron and steel. These are resources with a stable market value used in various civil infrastructure projects. As a team of environmental engineers, we wanted to know whether we could use iron-rich waste to produce iron oxide nanoparticles – a useful tool for combating water pollution and building engineering hardware.

All about nanoparticles

Iron oxide nanoparticles consist of iron and oxygen atoms and, because of their size, they exhibit unique physical and chemical properties. They are extremely small, typically at the nanoscale – one-billionth of a meter – in diameter.

The iron oxide nanoparticles we synthesized were a distinctive group called magnetite and maghemite. Initial studies have shown that nanoparticles in this group could help drugs get to the right part of the body, make batteries in electric vehicles more efficient and improve sensors for detecting toxic gas, as well as sound and motion.

Because these nanoparticles are made of iron, they’re both magnetic and stable. Their tiny size gives them a large surface area relative to their volume, allowing them to grab pollutants in water. Additionally, their magnetic nature makes them ideal for building extremely small and thin electrical components.

In our work, we wanted to find a new way to produce them using waste materials. In our newest study, published in the RSC Sustainability journal, we developed an eco-friendly method to synthesize iron oxide nanoparticles from expired over-the-counter iron supplements. This approach not only gives value to discarded products but also supports a more sustainable and circular method of production.

The research process

To conduct our study, we used a method called hydrothermal carbonization to produce these magnetic nanoparticles. We were able to source a large amount of expired iron supplements from a local health care center.

The hydrothermal carbonization process uses a turbocharged version of the kind of pressure cooker you might have in your kitchen. For our recipe, we combined 20 grams each of expired iron supplements and water in a specialized pressure reactor. We then cooked the mixture at 527 degrees Fahrenheit (275 degrees Celsius) for six to 12 hours. Under this intense temperature and pressure, the supplements broke down, which produced tiny – 10- to 11-nanometer – particles.

The end product included a solid charcoal-like material called hydrochar, which made up about 20% to 22% of the product. The hydrochar consisted of the iron oxide nanoparticles and graphite, a carbon-rich material that gave the hydrochar its charcoal-like look. The rest became gas and a dark, tarlike liquid separate from the hydrochar.

Hydrothermal carbonization is not the only method used to make iron oxide nanoparticles. There are other conventional methods such as coprecipitation, which involves mixing chemicals to form solids. Another method is pyrolysis, where materials are heated in the absence of oxygen. And finally, gasification, which heats materials in the presence of oxygen.

These methods usually require a higher energy input, around 1,292 to 1,832 degrees Fahrenheit (700 to 1,000 C), or harsh salt chemicals. In contrast, hydrothermal carbonization, the method we used, is water-based and can happen at a low temperature.

Initial research shows that nanoparticles created from iron clears some pollutants from wastewater. After creating the nanoparticles, researchers test them using a variety of scientific techniques. The nanoparticles have several potential future applications in the technology field.

We compared our hydrothermal carbonization process’s energy use with other methods and found it had the lowest environmental impact.

From polluted water to clean

The iron oxide nanoparticles we created are very useful for water treatment. They are particularly good at removing oil and heavy metals such as lead, cadmium, zinc and chromium from water. These are pollutants known to cause serious health issues, including cancer.

You can either mix them with polluted water or allow the water to pass through them, similar to a common household filter.

To test their performance, we mixed our iron oxide nanoparticles in wastewater samples containing methylene blue dye, a common pollutant in textile and manufacturing wastewater. We found they removed over 95% of the dye, and because the particles are magnetic, we could remove them from the treated water using a magnet so they didn’t contaminate the water.

Two vials of water, one a bright blue and one more clear.
Water polluted with methylene blue cleared up after treatment with iron oxide nanoparticles over 48 hours, and the nanoparticles attach to a magnet.
Yunus et al., 2025

Depending on the type of pollutants in the water, iron oxide nanoparticles can sometimes be reused after they’re heated again.

Moving forward

We produced a small amount of these nanoparticles in the lab for this study. However, large quantities of iron waste are sent to landfills. These include materials such as steel sludge and metal scraps. So in theory, many more of these nanoparticles could be produced in the future. If produced in large enough quantities, large water and wastewater plant filtration systems could use these particles to treat much larger amounts of water.

But landfill waste isn’t all one type of waste. Iron-rich waste may be contaminated with other materials, making its sourcing, sorting and recycling both resource-intensive and costly. To scale up this technology sustainably, researchers will need to first overcome these challenges.

On the bright side, economists predict that alternative metals, including iron oxide nanoparticles, may help meet production demands for future technologies and artificial intelligence. These nanoparticles can be used to manufacture high-performance computing components. These components include magnetic memory storage and semiconductors found in our everyday technologies.

Lots of the critical metals currently used are expensive, scarce or geopolitically sensitive: cobalt, nickel and lithium. As a result, our team is starting to explore how this hydrothermal carbonization-based method can be scaled and applied to other types of waste materials.

Our long-term goal is to expand the tool kit for sustainable nanoparticle production while continuing to address both environmental challenges and materials demands for future innovations.

History shows why FEMA is essential in disasters, and how losing independent agency status hurt its ability to function

When the head of the Federal Emergency Management Agency’s urban search and rescue team resigned after the deadly July 4, 2025, Texas floods, he told colleagues he was frustrated with bureaucratic hurdles that had delayed the team’s response to the disaster, acccording to media reports. The move highlighted an ongoing challenge at FEMA.

Ever since the agency lost its independent status and became part of the Department of Homeland Security in the early 2000s, it has faced complaints about delays caused by layers of bureaucracy and red tape, leaders at the top with little experience in emergency response, and whiplash policy changes.

Now, the Trump administration is cutting jobs at FEMA and talking about dismantling the agency, which would push more responsibility for disaster response to the states.

Yet, federal emergency management is crucial in America.

I run the Hazards Vulnerability & Resilience Institute at the University of South Carolina and for years have worked with states and communities facing hazards and disasters. To better understand FEMA’s value, let’s take a look back at how the nation responded to disasters before the agency existed, and what history reveals about when FEMA was most effective.

Disaster response without the US government

Before 1950, disaster relief and response were not considered a federal responsibility. When a hurricane, flood or tornado hit, community members and humanitarian groups, such as the American Red Cross or Salvation Army, brought in food, shelter and medical aid and solicited charitable donations to help people rebuild.

State and local governments had primary responsibility for disaster response. But mostly people relied on family, neighbors and charity.

Federal aid was approved on a case-by-case basis. War Department guidelines in 1917 stated that aid would be allowed only if a senior military officer certified that responding to the disaster would exceed local and state resources.

Then the Great Mississippi Flood of 1927 and the 1930s Dust Bowl gave new meaning to the concept of disaster in America.

In 1927, the Mississippi River broke through its levees, submerging more than 1 million acres of land across seven states. An estimated 700,000 people were displaced from their homes and workplaces.

Herbert Hoover, then U.S. commerce secretary, was given full authority to create, coordinate and carry out the federal relief effort. The Red Cross set up camps using tents provided by the War Department. Coast Guard and Navy boats rescued people stranded by flooding. But the response drew criticism for the lack of direct federal money to help flood survivors and the treatment of Black sharecroppers and laborers.

A few years later, the droughts of the Dust Bowl era began destroying crops in the Great Plains, causing widespread damage.

Federal disaster aid begins to take shape

After the flood, the federal government began to formalize its role in disaster management.

Flood control projects became a federal responsibility with the passage of the Flood Control Act of 1928. President Franklin D. Roosevelt’s New Deal provided emergency relief to farmers in the Great Plains and set up the Soil Conservation Service to help them reduce the effects of future droughts. These were among the first disaster mitigation policies at the federal level.

There was little coordination among agencies, however. Various aspects of disaster relief and recovery were handled by the departments of Defense, Agriculture, and Housing and Urban Development and the Small Business Administration. Each had its own rules and requirements.

In 1950, Congress passed the Federal Disaster Relief Act, establishing the first permanent authority for federal disaster relief.

The act gave the president the responsibility to determine how aid would be distributed and which agencies would be involved. The legislation also broadened the federal mission to include disaster preparedness and mitigation and formalized the process for issuing presidential disaster declarations.

The creation of FEMA

By the 1970s, large-scale disasters such as hurricanes Betsy (1965) and Camille (1969), and the fragmented disaster response, led the National Governors Association to call for a single comprehensive emergency management agency. Its report provided the blueprint for President Jimmy Carter’s 1979 executive order that established the Federal Emergency Management Agency, or FEMA.

The new agency became the home for emergency management within the executive branch. It was intentionally designed as an independent federal administrative agency that could work across federal agencies to support state and local governments in times of crisis.

FEMA wasn’t created to lead the disaster response. Instead it helps state and local officials by mobilizing federal resources, such as search and rescue, debris removal and funding when a disaster overwhelms the state’s capacity. FEMA could do this quickly because of established federal contracts and its ability to move equipment and responders into the region before a disaster hits.

When things began to fall apart

However, FEMA’s ability to act fast changed after the Sept. 11, 2001, terrorist attacks. The agency was restructured as a unit in the newly formed Department of Homeland Security. But the Department of Homeland Security’s focus was on terrorism and law enforcement, not natural disasters.

The loss of autonomy and direct reporting to Congress, unfunded mandates outside the scope of the 1988 Stafford Disaster Relief and Emergency Assistance Act, and major increases in the number of large and complex disasters stretched FEMA’s capabilities.

When Hurricane Katrina hit New Orleans in 2005, FEMA’s response drew widespread criticism. It was slow to deploy people and supplies and lacked enough experienced responders who knew what to do. Decision-makers were not familiar with new national response plans. Further breakdowns in communications and a lack of coordination among agencies led Congress to declare the Hurricane Katrina response a failure of initiative and agility.

FEMA’s reputation improved after the government brought in more experienced leadership and committed to preparedness planning and better response capabilities.

However, the first Trump administration, from 2017 to 2021, reversed those gains. Three different heads of FEMA in four years led to understaffing and conflicting directions.

FEMA had to battle misinformation during Hurricane Helene in 2024, including some amplified by then-presidential candidate Donald Trump.

As Trump took office for the second time in 2025, he and his administration talked about dismantling FEMA and pushing more disaster management to states. Job cuts and resignations at FEMA reduced the number of employees with training and experience vital in disasters. Political appointees to senior roles in the agency and in the Department of Homeland Security lacked emergency management training and experience.

A new policy that all purchases over US$100,000 be personally approved by Homeland Secretary Kristi Noem led to more resignations. For disaster response, a delay in waiting for a signature to work its way up the chain can cost lives.

What now?

Dismantling FEMA and leaving little or no federal coordination of disaster response puts states in a difficult position.

States must balance their budgets every year, and increasingly “rainy day” funds are insufficient to cover unexpected large disasters. As the federal government shifts other financial responsibilities to states, funds will diminish further.

A single disaster can cause hundreds of millions of dollars in damage and require widespread disaster response and then relief efforts. Since 1980, the cumulative cost of weather-related disasters has exceeded $2.9 trillion. With a warming atmosphere producing more intense storms, increasing human and economic harm are likely.

Members of Congress have proposed making FEMA an independent, Cabinet-level agency again. I see some distinct advantages in doing so:

  • Fewer management layers would enable faster deployment of federal supplies and personnel to assist disaster response.

  • A streamlined, more nimble agency could cut red tape for disaster survivors needing assistance, meaning delivering relief funding faster and more equitably.

  • If an independent FEMA had responsibility for recovery beyond its current 180-day reimbursement limits, that could improve long-term recovery efforts, especially if Congress provided permanent funding streams and consistent rules and regulations.

The Trump administration’s efforts to dismantle FEMA are shortsighted in my view. Instead, I believe the best move is to restore FEMA as an independent executive agency as it was originally envisioned.

Trump has promised to eliminate funding to schools that don’t nix DEI work – but half of the states are not complying

It’s been about six months since the U.S. Department of Education sent a “Dear Colleague” letter to all schools that receive federal funding, warning them that they could risk losing this money if they promote what the department calls “pervasive and repugnant” racial preferences.

The letter, among other things, reversed previous presidents’ positions on how diversity, equity and inclusion influences schools’ disciplinary measures. It advised schools to, within two weeks, begin to eliminate all discipline protocols rooted in DEI, on the grounds that this work is discriminatory against white students.

Trump also issued an executive order, “Reinstating Commonsense School Discipline Policy,” in April 2025, doubling down on the letter.

Trump’s letter and executive order exert an unusual level of influence over how schools can decide the best way to teach and, when necessary, discipline students. It also cuts against recognized research that Black, Latino and Native American students are disciplined more frequently and harshly than white and Asian students.

I am an educational scholar who has spent the past 13 years analyzing school discipline policy. While previous administrations have issued “Dear Colleague” letters to schools, Trump’s is the first that frames itself as though it were law – setting a potential new precedent for the executive branch to issue educational mandates without the approval of the judicial or congressional branches of government.

While all but two states have responded to Trump’s letter, about half of them have said they are not going to comply with its terms – despite the administration’s threat of cutting funding if they do not follow the guidance.

Understanding DEI in education

Equity-oriented education, or diversity, equity and inclusion, refers to an ideology and programming that intend to ameliorate patterns of racial inequality. In the context of discipline in schools, DEI strategies could include teachers having conversations with children about their behavior, rather than immediately suspending them.

Research shows that these techniques can help reduce racial discipline gaps in academic achievement and disciplinary outcomes.

The Obama administration in 2014 recognized this research in its own “Dear Colleague” letter to schools. The administration advised schools to either reform their discipline practices toward nonpunitive alternatives to suspension or risk being investigated for discrimination.

The first Trump administration rescinded this letter in 2018.

Then, in 2023, the Biden administration released a document along the same lines as Obama’s letter.

Trump’s February 2025 letter grouped all of these recommendations under the banner of “DEI” and argued that such practices are discriminatory, privileging students of color over white and Asian students.

In his April executive order, Trump reiterated that if schools did not eliminate DEI, they would be out of compliance with Title VI of the 1964 Civil Rights Act. This act prohibits discrimination on the basis of race, color or national origin,

Public school districts regularly have to issue a certificate of compliance to the government showing that their work is in line with Title VI.

While the Trump administration characterizes DEI as “smuggling racial stereotypes and explicit race-consciousness into everyday training, programming, and discipline,” it does not define exactly what constitutes DEI programming.

This puts school districts at risk of losing funding if they maintain any initiatives related to racial equality.

Legal concerns with Trump’s directives

The executive office and members of Congress typically issue “Dear Colleague” letters, which are not legally binding, to advise schools and others on policy.

Yet Trump’s letter was written like a mandate and reinforced by an executive order, which is legally binding.

Some scholars are calling the letter an “overreach” of legal authority.

In the spring of 2025, I analyzed states’ responses to Trump’s letter and executive order.

Two states, Iowa and Tennessee, had not yet provided public responses.

Twenty-three states complied with the administration’s directive by signing the letter as of May 30. Some, like Oklahoma, not only certified the letter but also passed state laws banning DEI policies and programs.

The remaining 25 states refused to certify the letter, asserting that they already complied with Title VI and that their policies are not discriminatory.

In addition, 19 of those 25 states sued the Trump administration over the letter in April, culminating in a court injunction later that month that temporarily released states from having to comply with its demands.

I noticed that many states that refuted Trump’s letter used the same exact words in their responses, signaling a concerted effort to resist Trump’s directives. States that did not sign on to the letter but objected to its intent generally resisted on legal grounds, ethics or both.

A legal argument

Most states that rejected it grounded their refusal to sign Trump’s letter in federal law. They cited the Civil Rights Act and the Paperwork Reduction Act, which protects states from having to file redundant paperwork. Because these states already certified compliance with Title VI, this argument goes, they should not have to do so again under Trump’s directive.

Education commissioners from a few states, including Illinois and Minnesota, also cited specific language used by Betsy DeVos, Trump’s former education secretary in his first term, who supported DEI policies.

Charlene Russell-Tucker, the education commissioner for Connecticut, also pointed out that in order for the federal government to cancel DEI programming, it would have to first legally change the definition of Title VI.

States resisting on other grounds

Some education officials also argued that their DEI work is ideologically necessary for providing supportive learning environments for all students.

Patrick Tutwiler, Massachusetts’ interim education commissioner, wrote in an April 16 letter, for example, that “Massachusetts will continue to promote diversity in our schools because we know it improves outcomes for all of our kids.”

Other officials displayed more subtle resistance. Randy Watson, Kansas’ education commissioner, for example, affirmed the state’s “commitment to comply with all Federal statutes,” including Title VI – but did not explicitly address Trump’s “Dear Colleague” letter.

Similarly, Kentucky informed the Department of Education of its compliance with federal law, while simultaneously encouraging local districts to continue diversity, equity and inclusion work.

Mississippi’s state department of education pointed out that school districts operate independently, so the state cannot force policies on them. However, Mississippi signaled compliance by citing a new state law banning DEI and confirmed that each of its individual school districts have already certified compliance with federal laws.

More legal pushback

It is not yet clear what might follow the April court injunction, which largely prevented the Department of Education from cutting federal funding to schools that continued their DEI-related programs and policies.

While the Trump administration has made major cuts to the Department of Education, it has not announced that states refusing to certify the letter will lose funding.

This is the first time an administration is issuing such a direct threat to withhold K-12 funding, placing schools in an unknown place, without a clear blueprint of how to move forward.

Insurance warning signs in doctors’ offices might discourage patients from speaking openly about their health

Source: The Conversation – USA (2) – By Helen Colby, Assistant Professor of Marketing, Indiana University

Have you ever noticed a sign in a doctor’s office saying that you may have to pay extra insurance costs if you discuss additional problems with your physician?

If so, you’re not alone. As health care spending continues to rise, providers are being asked to warn patients about any potential unexpected costs – for example, insurance charges for additional services at an otherwise fully covered annual wellness visit.

A sign labeled 'Attention: Important insurance information' reads 'Our office does NOT want you to be surprised by a bill, but we must ALWAYS report to your health plan the actual services rendered.'
The sign that inspired it all.
Helen Colby

But our research shows these warning signs could have an unintended consequence, discouraging patients from speaking openly with their doctors.

We are professors who research how people make spending decisions and were inspired to study this issue by real signs at a university-affiliated health care office. Other researchers have found many reasons why people hesitate to speak openly with their doctors, and we wondered whether these signs might be another factor. So we conducted some experiments.

In two studies, we found that when people saw an insurance warning sign, they were less willing to raise a wide variety of issues during a physical exam. These included both short-term issues such as headaches, fatigue and arthritis pain in the finger joints, and previously diagnosed, chronic conditions including high blood pressure, Type 2 diabetes and asthma.

In a third study, we tested whether it was what the sign said – or just the mere presence of a sign mentioning costs – that made people reluctant to speak up. We showed participants either no sign, an insurance warning sign, or a sign about a prescription drug discount program, which was also modeled after a real sign in the same doctor’s office. Only people who saw the insurance sign were less likely to speak up.

Why it matters

Frank conversations between patients and providers are essential for good health care. They allow providers to tailor medications, reduce side effects and find treatments that are right for each patient. What’s more, treating issues earlier rather than later generally leads to better outcomes and costs less in the long run.

We found that insurance warning signage, no matter how necessary or well intended, can discourage patients from sharing important health information. This could cause delays in important care, leading to unnecessary discomfort and stress as patients suffer with untreated issues.

Health care offices need to include certain insurance disclosures to inform patients of their rights under the No Surprises Act, which took effect in 2022. However, providers and administrators should be aware that their patients may often have cost concerns.

Doctors’ offices can try to find ways to communicate potential insurance costs while also encouraging patients to have open and honest discussions with their providers. The signage at the office that inspired this work had many words bolded and underlined, which may have made it feel especially aggressive to some patients.

It’s important for patients to know that they should never ignore symptoms. In fact, raising a concern as early as possible with a doctor or another health care provider can save more money down the road.

What still isn’t known

We weren’t able to study the long-term impacts of such signs, and it’s possible they have even more negative effects than we uncovered – for example, by making patients reluctant to have annual wellness visits.

It’s also unclear how often health care professionals actually report such conversations to insurers, especially when the issues are brought up briefly during a checkup and don’t require additional testing or treatment at that time.

But the research is clear on one point: When patients feel they can speak freely to their doctors, they get better care. That’s why doctors and other health care professionals should be aware that even well-intended warning signs may encourage patients to keep silent.

The Research Brief is a short take on interesting academic work.

Youth athletes, not just professionals, may face mental health risks from repeated traumatic brain injuries

On July 28, 2025, a 27-year-old gunman entered a New York City office building that is home to the National Football League’s headquarters. He shot and killed four people and injured one other before killing himself.

In a note found in his wallet, he claimed he had chronic traumatic encephalopathy, or CTE, a degenerative brain condition believed to develop from repeated traumatic brain injuries. He asked experts to study his brain.

CTE has received much attention over the past two decades as multiple NFL players have been diagnosed with the condition after their deaths. The 2015 movie “Concussion,” about a forensic pathologist named Dr. Bennet Omalu who documented the first case of CTE in an NFL player, also highlighted the issue.

The gunman in the New York City shooting played high school football, but he did not play professionally. It is not known whether he had CTE.

I’m a clinical psychologist who studies mental health issues and their relationship to physical illness. Although people generally associate CTE with professional athletes, a growing body of research, including my own work, shows that adolescents and young adult athletes experience traumatic brain injuries that can have both short-term and long-term effects on mental health. In my view, young players and their families, as well as coaches, should pay attention to these emerging risks.

A 27-year-old gunman who targeted NFL headquarters in New York City on July 28, 2025, believed he had chronic traumatic encephalopathy.

From traumatic brain injuries to CTE

At least 55 million people worldwide are thought to experience a traumatic brain injury each year. The actual number may be higher, as many brain injuries are never diagnosed or treated.

Some people with a brain injury recover quickly. Others do not. Over half of people with a brain injury reported mental health symptoms one year later. These include difficulties concentrating, memory problems and irritability, as well as physical concerns such as recurrent headaches and difficulties with balance. Many people who sustain a traumatic brain injury also report difficulties with anxiety, depression and substance misuse as they are recovering. Some report thoughts about ending their lives or suicide attempts.

Although the link between traumatic brain injuries and CTE is still being studied, many experts believe that the condition is caused not by a single, severe blow to the head but by repeated trauma to the head over time.

It is not uncommon for former competitive athletes across a range of contact sports to believe they may have CTE – not only because they remember the injuries or being diagnosed with a concussion, but also because they experience many of the cognitive symptoms that affect people with traumatic brain injuries and sometimes misuse alcohol, pain medications or other substances to cope with them.

However, there’s no way for someone to get a diagnosis for the condition while they are experiencing these symptoms. There is currently no test for CTE. Doctors generally diagnose it after an autopsy.

Repeated brain injuries in youth sports

The focus on CTE has brought greater interest in the effects of traumatic brain injuries in general. Such injuries are common not only in professional athletes but also in adolescents and young adults who play sports. They are seen frequently in military veterans as well.

In a study published in March 2025, my colleagues and I assessed more than 500 varsity and club sport athletes. We found that 75% said they had experienced a head injury before starting college. Almost 40% reported being diagnosed with at least one concussion, and just over half of those athletes experienced a loss of consciousness.

We also found that student athletes who had experienced head injuries were much more likely to be diagnosed with at least one psychiatric disorder in their lifetime. They were more likely to drink alcohol excessively and have a substance use disorder in their history. Greater symptoms of an alcohol use disorder were associated with having their first head injury at an earlier age, as well as having more head injuries, diagnosed concussions and losing consciousness from those injuries.

These troubling observations highlight the often overlooked mental health effects of head injuries in adolescents and young adults. Our study aligns with others that have found a relationship between sports-related traumatic brain injuries and mental health symptoms – and it is among the first to look not only at self-reported symptoms but also at formal psychiatric diagnoses.

How exactly these cases might relate to CTE is unknown, but there are hints of a link: Researchers examining the records of 152 former contact sport athletes who died before age 30 identified signs of CTE in the brains of 40% of them. Family members described mental health symptoms in the majority of them, and alcohol and substance misuse were reported in approximately one-third.

Increasing safeguards for brain health in young athletes

While head injuries in youth sports were once met with a shrug, youth sports leagues are increasingly paying attention to the issue.

Studies suggest that limiting the amount of physical contact in preseason training or between games can reduce young players’ head injury risks. Coaches of contact sports such as football and soccer often receive training on identifying the signs and symptoms of head injuries and are given strategies to manage them.

Athletic trainers, routinely available at many high school sporting events, are involved in sporting events for younger children as well. As first responders to athletic injuries, they are trained to assess symptoms of head injuries and can provide guidance, as part of a medical team, on when an athlete can return to play. Athletic trainers also may be well positioned to observe some of the mental health symptoms commonly seen after head injuries.

Following a head injury, parents and guardians should also keep an eye on their athlete. Changes in mood or behavior after a head injury warrant a referral to a neurologist or mental health professional for additional assessment and treatment.

The Druze are a tightly knit community – and the violence in Syria is triggering fears in Lebanon

Source: The Conversation – USA (3) – By Mireille Rebeiz, Chair of Middle East Studies, Dickinson College

Violence continues several weeks after clashes started between armed Bedouin clans, Sunni jihadist groups and Druze fighters on July 14, 2025, in Sweida, a city in southern Syria.

Hundreds of Druze were killed in the clashes, and Syria’s defense minister deployed forces to contain the sectarian fighting.

The Druze are a religious minority in the Levant, the region covering roughly modern-day Syria, Lebanon, Jordan, Israel and Palestinian territories. The faith originated in Egypt as an offshoot of the Fatimid tradition, a branch of Shiite Islam. Today, there are about 1 million to 1.5 million Druze worldwide, more than half of whom live in Syria. Most others live in Lebanon, Israel, Jordan and the Israeli-occupied Golan Heights.

We are experts in Druze and Lebanese history, and we know that the conflict in Sweida is regarded by the Druze of Lebanon – and the Druze everywhere – as a deeply personal matter.

What’s more, the horror stories coming out of Sweida are reverberating in Lebanon, where many Druze also fear the risk of sectarian violence, and distrust in current leadership.

Bonds forged through a long history

Many scholars attribute the strong bond between the Druze of Syria and Lebanon to their shared faith – which is partly true – but they often overlook an equally vital element: a collective conscience shaped by a distinctive origin story.

The Druze see themselves as an ancient, blood-related tribal coalition that evolved into an extended family spread across regions. This self-perception is so deeply rooted that it gave rise to a well-known Levantine saying: “The Druze are like a copper plate – wherever you strike it, it rings.”

According to local tradition, several Druze families from Mount Lebanon migrated to the Hawran region, south of Damascus, more than three centuries ago, paving the way for thousands of others to follow. Sweida is the capital city of the Druze region in Ḥawran. The region of Ḥawran is the second-youngest Druze settlement – after Jordan – dating back to the 18th century.

A foundational event in the community’s modern history was the Druze uprising in Ḥawran against the Ottoman governor of Egypt, Muhammad Ali Pasha, in 1837.

The governor had insisted on imposing conscription and disarmament on the Druze. The community rebelled since both measures would put their security and autonomy at risk, and the governor sent the army to occupy the Levant.

During the revolt, Druze from Mount Lebanon and Wadi al-Taym – a historical Druze region encompassing the modern-day Lebanese districts of Rashayya and Hasbayya in the southeast, near the Syrian border – rose up to divert the Egyptian army and sent fighters to support their Syrian kin.

In 1838, many of these Lebanese fighters were killed, particularly in what is known as the Battle of Wadi Bakka, near the Lebanese-Syrian border; an entire Druze battalion was besieged by the Egyptian forces and nearly wiped out.

In 1860, a third civil war involving the Druze under the Ottomans broke out in Mount Lebanon between the Druze and the Maronites. The Maronites are a group of Eastern Catholic Christians predominantly in Lebanon. The conflict centered on control of the southern regions of the mountain – historically known as the Druze Country.

As violence escalated between the two communities, the Druze of Ḥawran came to the aid of their fellow Druze in Mount Lebanon, tipping the balance in their favor.

During World War I, Mount Lebanon was hit by a famine and around 200,000 people died. The Druze of Ḥawran supported the Druze in Lebanon by supplying them with essential grain, and many Lebanese Druze resettled in Ḥawran to escape starvation.

These are just a few examples from a long history of mutual support that, in the Druze collective memory, reinforces the belief that they are not merely a community – but a tightly knit extended family that spans national borders.

Shifting borders

As a religious minority in the Levant, the Druze have long defended their religious freedom and identity.

The principalities in Mount Lebanon were most successful at realizing and keeping religious autonomy from at least the 12th century to the 19th century; they ensured the Druze were ruled by one of their own emirs and could practice their religious and social customs freely. The modern state of Lebanon evolved out of these autonomous principalities.

However, the Druze never viewed their struggle for social and religious autonomy as a license to attack their neighbors – especially fellow Arab Muslims – but rather as a safeguard for their faith and security.
The Druze do not equate religious freedom and autonomy with independence. In fact, many Druze in the region oppose the idea of a Druze state.

Starting in the 1930s, Zionist leaders hoping to create a Jewish state sought to exploit this Druze desire toward autonomy by proposing the creation of a Druze state in Ḥawran. They envisioned it as a friendly buffer state bordering the future state of Israel. More importantly, they wanted to push Druze out of Galilee and Mount Carmel knowing that they lived there for many centuries.

After the Six-Day War in 1967 between Israel and Egypt, Jordan and Syria, this idea expanded into a broader Israeli plan to fragment Syria and Lebanon into five sectarian states: an Alawite state in the north, a Christian state in the west, a Druze state in the south, a Kurdish state in the east and a Sunni state at the center.

Since Oct. 7, 2023, some Druze leaders – such as Walid Jumblatt, former minister, and head of the Progressive Socialist Party – have raised concerns that Israel could be attempting to revive this plan to reshape the region into a “New Middle East” with potentially new borders in Syria, Iraq, Lebanon, and the Palestinian territories. In fact, since the fall of the Assad regime in Syria, Jumblatt has been vocal about the rise of potential new borders.

Historically, the highest Druze religious authorities rarely engage in day-to-day politics. Yet, they are still expected to offer moral and political guidance during times of crisis, as the community sees them as guardians of faith, identity and ethics.

Recently, the leading Druze spiritual authority in Lebanon, Sheikh Amin al-Sayegh – who has been at odds with Jumblatt on internal communal affairs – voiced similar concerns in a public letter of condolence and support to the Syrian Druze. He emphasized the community’s Arab Islamic identity and warned against prioritizing material security over the historical Druze identity. Al-Sayegh’s stance reflects long-standing Druze political principles rooted in centuries of tradition.

The political message was clearly hinting at a rising tendency among some Druze, including Syrians, to consider stronger ties with Israel for security purposes.

Growing fear of sectarian violence

Lebanon has a long history of sectarian violence, and the recent events in Syria are indeed alarming to Lebanon’s religious minorities, including the Druze.

In March 2025, over 1,400 Alawite civilians were massacred, mostly in coastal cities like Latakia and Baniyas, by the newly formed Syrian forces.

In June, 25 Syrian civilians were killed and over 60 injured when a Sunni extremist group attacked the Greek Orthodox Church of the Prophet Elias in Damascus. And as of mid-July, Bedouin clans and the state security forces of the Sharaa regime have been targeting and killing Druze civilians in Sweida.

With numerous Bedouin tribes present in Lebanon, and tension evolving into an open sectarian confrontation, Druze leaders there fear that the sectarian violence could spill over into their own communities due to the Syrian Bedouins’ call for general mobilization of Arab tribes in the region against the Druze. This call is based on unverified reports of Druze killing Bedouin civilians.

Druze leadership in Lebanon

Despite growing frustration over Lebanon’s deepening economic crisis – partly attributed to political leadership – most Lebanese Druze remained loyal to traditional figures like Jumblatt, who was long viewed as the most capable guardian of their security and communal interests.

But the shock of recent violence in Sweida, where militias aligned with the Syrian regime targeted Druze civilians, has unsettled that loyalty. Many Lebanese Druze had expected their leaders to use their external influence to shield their kin across the border. The perceived failure to do so – combined with Jumblatt’s continued support for the regime led by President Ahmed al-Sharaa in Syria – has sparked widespread criticism within the community. Jumblatt himself acknowledged this strong criticism in a recent interview.

For many Druze, the brutal events in Sweida were fiercely traumatic and have forced them to painfully confront their long-standing core political priorities: security and the preservation of religious and social autonomy. And in light of this, some are beginning to reassess long-held assumptions that current leadership can preserve their religious autonomy and, more importantly, keep them safe.

Le changement climatique aggrave le fardeau de la dette africaine : de nouveaux contrats de dette pourraient aider

Source: The Conversation – in French – By Magalie Masamba, Extraordinary lecturer at the Centre for Human Rights, University of Pretoria

De nombreux pays africains croulent sous le poids de la dette. Le changement climatique aggrave encore la situation. L’Afrique contribue le moins aux émissions mondiales, mais souffre le plus des phénomènes météorologiques extrêmes, de la hausse des températures et de la sécheresse. Ces catastrophes affectent non seulement les moyens de subsistance des populations, mais aussi les recettes nationales, rendant le remboursement de la dette plus difficile. Or, les contrats de dette traditionnels ne prennent pas en compte cette réalité.

Le lien entre la dette et le climat devient de plus en plus indéniable. À mesure que les catastrophes liées au climat s’aggravent, les pays endettés disposent de moins de ressources publiques pour protéger leurs écosystèmes naturels et investir dans la santé et l’éducation.

Lorsque des pays consacrent davantage de ressources au remboursement de leur dette qu’à la santé ou à la résilience climatique, ce n’est pas seulement un signe de défaillance du système, c’est une injustice. C’est la réalité à laquelle sont confrontés aujourd’hui de nombreux pays africains.

Dans le cadre de la recherche de solutions à ce problème, mes récentes recherches ont examiné si les instruments de dette conditionnelle de l’État pouvaient constituer une piste utile.

Les instruments de dette conditionnelle de l’État sont généralement garantis par des banques de développement ou des bailleurs de fonds pour le climat. Ils sont liés à des chocs prédéfinis qui affectent l’économie d’un pays. Il peut s’agir d’une baisse de la production économique (produit intérieur brut) qui réduit les recettes publiques. D’autres chocs peuvent être dûs à des phénomènes météorologiques extrêmes et au changement climatique, qui perturbent l’activité économique et augmentent les dépenses nécessaires pour reconstruire les infrastructures, entre autres. Ces chocs peuvent réduire la capacité d’un gouvernement à rembourser ses dettes.

Lorsque de tels chocs se produisent, les instruments de dette conditionnelle de l’État permettent de réduire, de suspendre ou d’ajuster temporairement le remboursement de la dette, aidant ainsi les pays à éviter le défaut de paiement tout en se concentrant sur la reprise.

Chaque instrument de dette conditionnelle à la situation de l’État est structuré différemment, mais l’objectif fondamental reste le même : donner aux pays une marge de manœuvre financière lorsqu’ils sont confrontés à des chocs externes tels que des catastrophes climatiques ou des ralentissements économiques.

Ils sont déjà utilisés dans certains pays. On peut citer, par exemple, les obligations catastrophe de la Jamaïque, qui prévoient la suspension des remboursements en cas d’ouragan, ainsi que les obligations liées à la durabilité du Rwanda, destinées à mobiliser des capitaux privés pour soutenir ses objectifs climatiques. Un autre exemple est l’obligation liée au produit intérieur brut (si le PIB d’un pays diminue pendant une crise, les remboursements sont réduits).

En théorie, ces instruments pourraient alléger la pression financière lorsque les pays ont le plus besoin d’aide. Cela permettrait aux gouvernements de donner la priorité aux populations et à la planète plutôt qu’aux créanciers.

Je suis expert juridique et politique spécialisé dans la dette souveraine (le montant emprunté par un gouvernement), le financement de la lutte contre le changement climatique et la gouvernance économique mondiale. J’ai examiné plusieurs types d’instruments de dette conditionnels, analysé des rapports officiels et consulté des publications universitaires et politiques afin de déterminer comment ceux-ci pourraient fonctionner pour les pays africains.

Mes recherches ont montré que si certains pays ont obtenu des résultats mitigés avec ce type de contrats de dette, d’autres ont rencontré des difficultés. Il s’agit notamment de litiges concernant les conditions de déclenchement (les événements spécifiques qui activent les modifications des conditions de remboursement, comme une catastrophe naturelle ou un choc économique) et les primes élevées exigées par les bailleurs de fonds.

La faible notation de crédit de nombreux pays africains rend également les prêteurs réticents à conclure ce type de contrats.

Mes conclusions suggèrent que, bien que ces instruments soient prometteurs, ils ne constituent pas une solution automatique au problème actuel du remboursement de la dette. Néanmoins, s’ils sont mis en place de manière juridiquement irréprochable, ils pourraient constituer un élément précieux d’un système financier plus juste et plus résilient, en particulier s’ils sont associés à un allègement de la dette et à des règles multilatérales plus équitables.

La présidence sud-africaine du G20 : une opportunité

En tant que pays exerçant la présidence du G20, l’Afrique du Sud peut porter la voix du continent pour exprimer l’urgence d’une architecture financière plus équitable. L’Afrique du Sud devrait promouvoir un cadre multilatéral pour le rééchelonnement de la dette souveraine. Il s’agit d’un processus par lequel un pays restructure ou renégocie sa dette publique avec ses créanciers lorsqu’il n’est plus en mesure de respecter ses obligations de remboursement.

Un tel cadre devrait inclure tous les créanciers et tous les débiteurs. Son objectif devrait être de restructurer rapidement la dette et de veiller à ce que les pays ne s’endettent pas au point de ne plus pouvoir investir pour se protéger contre les catastrophes climatiques.

L’Afrique du Sud a mis en place le Groupe d’experts du G20 Groupe d’experts africains pour relever les défis liés à la dette. Dans le but de rationaliser les programmes de financement climatique et de restructuration de la dette souveraine, le groupe peut faire pression pour que des instruments de dette conditionnelle et d’autres outils de dette plus équitables soient mis à l’essai.

L’expert en gouvernance économique mondiale Danny Bradlow et le chercheur Kesaobaka N. Mopipi ont également suggéré que le groupe d’experts doit identifier les obstacles qui empêchent les pays africains d’accéder à des financements abordables, prévisibles et axés sur le développement. L’Afrique du Sud devrait également travailler avec l’Union africaine afin de présenter une position africaine unifiée lors des grands sommets mondiaux. Il s’agit notamment de la COP30 et de la Quatrième Conférence internationale sur le financement du développement. Cela contribuerait également à garantir que les programmes africains en matière de dette, de développement et de financement de la lutte contre le changement climatique ne soient pas traités de manière isolée, mais comme des défis étroitement liés nécessitant des solutions intégrées.

L’Afrique du Sud devrait saisir cette occasion. La présidence du G20 est plus que symbolique. Il s’agit d’une plateforme permettant de remettre en question des normes obsolètes et de mener la charge vers un système mondial de dette au service des populations, de la planète et des générations futures.

Que faire maintenant ?

Tout d’abord, la conception est importante. Les instruments de dette conditionnels à l’État doivent être équitables, transparents et adaptés aux besoins des pays. Des règles claires doivent automatiquement s’appliquer lorsque certaines conditions sont remplies, par exemple lorsqu’un pays est frappé par une catastrophe climatique. Ces règles doivent être faciles à appliquer et alignées sur les plans climatiques et de développement de chaque pays.

Il est également important que les indicateurs clés, tels que le produit intérieur brut, reflètent fidèlement les réalités locales. Dans de nombreux pays africains, une part importante de l’activité économique se déroule dans le secteur informel. Celle-ci est souvent sous-estimée dans les statistiques officielles. Plus important encore, les gouvernements africains devraient prendre l’initiative de définir la conception des nouveaux instruments de dette afin de s’assurer qu’ils soutiennent véritablement les priorités nationales et n’aggravent pas les risques futurs.

Deuxièmement, un soutien technique est essentiel. Il est nécessaire d’investir dans les capacités techniques, l’expertise juridique et la coordination intersectorielle afin de garantir le bon fonctionnement de ces instruments de dette. Les institutions multilatérales, telles que la Banque mondiale, la Banque africaine de développement et d’autres banques régionales de développement, ainsi que d’autres partenaires de développement, doivent appuyer les efforts des gouvernements pour renforcer ces capacités.

Enfin, la convergence des enjeux liés à la dette, au climat et à la conservation en Afrique exige des solutions créatives, justes et tournées vers l’avenir. Toute solution durable en matière de dette doit reconnaître que l’Afrique en particulier, et les pays du Sud en général, ne doivent pas supporter le coût d’une crise climatique qu’ils n’ont pas causée. Les systèmes internationaux de dette doivent être profondément réformés pour devenir plus équitables, transparents et adaptés aux réalités des économies menacées par le changement climatique.
