Congratulations to Simon Briole, Junior Professor Chair at CEE-M, who has officially joined the Abdul Latif Jameel Poverty Action Lab,(J-PAL Europe) network as an “invited researcher” for a three-year period.

The Abdul Latif Jameel Poverty Action Lab brings together affiliated researchers from universities around the world. It is organized into seven regional offices, each hosted by a local university.

J-PAL Europe is committed to reducing poverty by ensuring that social policies are grounded in rigorous scientific evidence. Its approach relies on randomized controlled trials (RCTs), which make it possible to accurately measure the effectiveness of social interventions. The organization then shares these findings with governments, NGOs, and donors to support the scaling up of effective programs.

Created in 2014 by two members of the CEE-M, Sophie Thoyer and Pauline Lécole, the CAPeye website brings together a wide range of resources to explore, analyze, and deepen one’s understanding of the Common Agricultural Policy (CAP). We met with the two coordinators of this monitoring and training initiative dedicated to the CAP..

• What led you to create the CAPeye platform? What needs were you aiming to address?

What led you to create the CAPeye platform? What needs were you aiming to address?

The original idea, when we launched CAPeye, was to design a tool that could serve two main purposes. The first was to provide information on a regular basis, but not in the same way as the press or mainstream media. We wanted to deliver content that is more thoroughly analyzed and better explained, aimed at a specific audience.

The second objective was to collect and offer training resources on the Common Agricultural Policy (CAP). We wanted to provide courses accessible to everyone: those who are not very familiar with the CAP but wish to understand how it works, how it is funded and decided, as well as those who already have some knowledge and are looking for more in-depth, specialized insights. We therefore organized the content into two main categories: “CAP for Beginners” and “CAP for Experts.”

• You mentioned a specific audience — who exactly are you targeting?

First of all, it is important to clarify that we are not addressing farmers who want to learn how to complete their CAP declarations or estimate the subsidies they are entitled to. Our goal is not to replace agricultural advisory services, but rather to clearly explain how the CAP was built, its objectives, and how it has evolved over time.

We primarily target an informed audience that seeks to better understand the logic behind CAP interventions. This includes researchers, academic staff, and secondary or technical education teachers. For instance, an agronomist working on crop rotation may need to understand how public policy incentives related to crop diversification function.

Our second target audience consists of master’s students, engineering students in agronomy, spatial planning, or natural resource management. This audience is often in a learning phase and can benefit from CAPeye as a way to gain a broad and structured overview of the CAP.

Finally, our website is also widely used by media professionals and journalists. When agricultural issues make the headlines, they need to understand the CAP—its regulations and mechanisms—since it frames agricultural activity in France and across Europe. For non-specialists, this is highly complex. We are therefore frequently contacted by journalists seeking clarification, as the CAP is a particularly intricate topic.

• CAPeye also offers online training. Could you tell us more about the content you provide?

For all these audiences, we felt it was important to offer targeted training on the CAP, whether for self-learning or for deepening specific topics.

On CAPeye, we provide two types of training. The first is called “CAP for Beginners,” which is freely accessible. Users can find short video clips, concise PowerPoint presentations, and thematic dossiers covering major CAP periods or specific topics such as “peri-urban agriculture and the CAP” or “mountain agriculture.” All of this content is designed to help users understand why agricultural policies are needed, why the CAP exists, how it functioned in the 1960s, how it works today, and so on. To help users assess what they have learned, we also provide a series of quizzes.

We also offer more advanced content in the form of structured courses. These are available upon free registration and are distributed under a Creative Commons license, making them freely accessible. Several modules are specifically dedicated to the CAP, such as its purpose, its history, and so on. We also provide an additional module on public policy evaluation.

In total, we offer around ten online courses that can be followed independently of one another. It is not a MOOC, as there is no predefined progression between the available courses.

• There is also the “News” section, which could even be described as “News Analysis.” How do you choose your topics and sources?

Our objective is not to simply reproduce information that can be found elsewhere. We aim to provide thoughtful content that takes a step back, drawing on our expertise to place current events within a broader historical and contextual perspective, and to explain the underlying reasons and mechanisms behind them.

As for topic selection, it varies. Sometimes we jointly decide to address a topic from an original angle. At other times, we build on the research we conduct with our PhD students or interns. For example, we wrote an article on the history of CAP simplification—a topic that is currently in the spotlight due to farmers’ protests, but which has in fact been part of the CAP reform agenda for over 30 years and is the subject of ongoing doctoral research.

Regarding sources, we subscribe to Contexte Agro, which allows us to closely follow developments in agriculture and agricultural policy. It is a very comprehensive but paid source. We also monitor general media outlets such as France Info, Libération, and Le Monde, as well as professional press and more specialized journals where valuable insights can sometimes be found. However, we try as much as possible to go directly to primary sources. We therefore also follow platforms such as Euractiv, and more specifically for CAP-related issues, CAP Reform, a blog run by an Irish colleague.

Keeping up with the news also requires time, as developments move very quickly. We have therefore moved away from a twice-monthly publication schedule. Today, we publish less frequently, which suits us better, as we prioritize quality over quantity.

Today, our newsletter has more than 400 subscribers, and CAPeye offers a comprehensive resource with over sixty news analyses that can be searched by keywords. All articles are archived on the platform, as we believe it is important to preserve these analyses, which contribute to documenting the evolving history of the CAP.

Article CAPeye: a leading resource on the Common Agricultural Policy appeared first on Center for Environmental Economics - Montpellier.

“Too much tax kills tax,” says the famous phrase by the American economist Arthur Laffer. But what if, for France, it were more complicated than that? Aren’t there other social, emotional, or moral considerations at play?

Although taxation has historically been the financial tool used to collect the resources necessary for the functioning of the state, it is nonetheless a complex social phenomenon. This is what our research has highlighted. Because alongside financial gain, many other social, emotional, or moral considerations help explain our complex relationship with taxation.

In an article published in The Conversation, Cécile Bazart (University of Montpellier, CEE-M), Aurélie Bonein (University of Rennes), and The Conversation, Cécile Bazart (University of Montpellier, CEE-M) examine the current underlying factors behind the loss of legitimacy of tax collection.**

Article Visiting : Marie-Ève Gaboury-Bonhomme, from Laval University (Quebec) appeared first on Center for Environmental Economics - Montpellier.

Since the winter of 2024, farmers’ mobilisations have often been portrayed in the media as a widespread rejection of environmental regulations. But is this really the case? What do the farmers involved in these protests actually say?

A large-scale study conducted in France, Germany, Belgium and the Netherlands provides a more nuanced perspective. It shows that, depending on the country, the weight of environmental regulations ultimately appears to be a secondary issue, even though it has been at the heart of political responses to the protests.

In an article published in  The Conversation, Sophie Thoyer and Pauline Lécole analyse the drivers of this contestation at the European level and present the main findings of the study they conducted with several European researchers. The results have been published in the scientific journal Food Policy.

Article Farmers’ Mobilisations in Europe: Beyond the Rejection of Environmental Regulations appeared first on Center for Environmental Economics - Montpellier.

Climate change is affecting agriculture first and foremost, with particularly strong impacts in certain highly exposed territories. Just a few dozen kilometres from Montpellier, the Haut-Languedoc — a predominantly rural area covering nearly 1,900 km², stretching from the Orb valley in the north to Capestang in the south, and from the Lauragais plain in the west to the Béziers area in the east — provides a striking illustration of these dynamics.

Over the past twenty years, the number of farms in the region has fallen by nearly 60%. This sharp decline raises serious concerns about the territory’s capacity for resilience. While climate change is not the sole cause, it is likely to become a major driving factor in the coming years if no action is taken. This leads to a central question: how can the resilience of local agricultural systems be strengthened?

To address this issue, Abderaouf Zaatra (CIHEAM), Mélanie Requier (CIHEAM) and Hélène Rey-Valette (CEE-M) were guests on the radio programme À l’UM la Science, broadcast on Divergence FM on 22 January 2026 and now available as a podcast. During the discussion, they presented findings from a study conducted with Thierry Blayac and Hatem Belhouchette (CIHEAM), combining two complementary approaches: an objective assessment of farm vulnerability and an analysis of farmers’ own perceptions of the vulnerability factors they face.

In an article published in the Swiss daily Le Temps , Sophie Thoyer, Research Director at INRAE (CEE-M) and a specialist in the Common Agricultural Policy (CAP), sheds light on the factors behind France’s opposition to the EU–Mercosur trade agreement.

According to her, the European Commission has, overall, negotiated the agreement relatively well. “If we take the example of the French beef sector, the agreement poses relatively limited risks to its future. The import quota from Mercosur countries, with reduced tariffs set at 7.5%, amounts to 99,000 tonnes for the entire European Union. For France, this represents roughly 250 grams per person per year,” she explains. She nevertheless points out that competition could intensify for certain cuts of beef that are particularly valued by French consumers and on which the sector generates most of its margins. She also notes that progress has been limited with regard to so-called “mirror measures”, which aim to ensure that imported products comply with environmental, sanitary, and social standards equivalent to those applied within the EU.

Sophie Thoyer also recalls that, “in France, perhaps more than elsewhere, agriculture remains a structuring pillar despite its relatively small share of GDP. Large agricultural cooperatives play a significant role in exports, and the prominence of agriculture in political discourse has deep historical roots.” These factors are compounded by growing concerns surrounding the renegotiation of the Common Agricultural Policy. As the largest beneficiary of EU agricultural subsidies, France could see farmers’ incomes affected by any reduction in funding. “This issue has been present in the background since March 2024 and mobilises farmers who are not directly concerned by slaughtering or exports. Over the past two years, agricultural incomes have declined significantly, prompting many farmers to express a deep sense of distress,” she observes.

Article CEE-M Workshop on Dynamic Problems in Environmental and Resource Economics, January 13, 2026 appeared first on Center for Environmental Economics - Montpellier.

Drawing inspiration from one’s peers—and thereby modifying one’s own practices—is a behavioural pattern frequently observed across various contexts. As this article illustrates, it can also constitute a substantial lever for reducing pesticide use, particularly when directives perceived as ‘top-down’ lead those most affected to resist change.

Authored by Rose Deperrois (CEE-M and UMR GAEL), Julie Subervie (CEE-M), Adelaïde Fadhuile (UMR GAEL) and Solal Courtois-Thobois (CEE-M, Sciences Po Lyon), the article presents findings stemming from a study previously published in the European Review of Agricultural Economics. It highlights how peer influence can effectively support the evolution of farmers’ practices.
