President Claudia Sheinbaum has reshuffled the leadership of Mexico’s agricultural sector, appointing Columba Jazmín López Gutiérrez as the new head of the Secretariat of Agriculture and Rural Development (Sader). The move comes following the resignation of Julio Berdegué Sacristán, a transition that signals a strategic pivot as Mexico prepares for the high-stakes review of the United States-Mexico-Canada Agreement (USMCA).
The appointment of López Gutiérrez marks a historic first for the administration, as she becomes the first woman to lead Mexico’s agricultural policy. Her arrival is not merely a personnel change but a re-alignment of the country’s agro-ecological strategy, integrating a focus on sustainable development and productive inclusion as the nation navigates complex trade tensions with its northern neighbor.
While Berdegué has stepped down from his role as Secretary, he remains within the administration. The government has indicated that he will transition into a strategic role, advising and coordinating international agricultural affairs. This arrangement allows the administration to retain Berdegué’s expertise in trade diplomacy specifically to defend Mexican agricultural interests during the upcoming USMCA review process.
A Strategic Shift in Agricultural Leadership
Columba Jazmín López Gutiérrez enters the role of Secretary of Agriculture with a deep background in agroecology and rural development. An agricultural engineer by training from the Universidad Autónoma Metropolitana, she brings more than 30 years of experience to the position. Prior to this appointment, she served as the undersecretary of Productive Inclusion and Rural Development within the Secretariat of Welfare, where she focused on the socio-economic integration of small-scale producers.
López Gutiérrez’s background suggests a shift toward a more sustainable, agro-ecological approach to farming. Her previous leadership of the Commission of Natural Resources and Rural Development in Mexico City underscores her expertise in balancing urban expansion with the preservation of rural productive zones. This expertise is expected to play a critical role as Sheinbaum seeks to modernize the countryside while adhering to environmental standards that are increasingly scrutinized in international trade agreements.
The transition occurs at a moment of significant vulnerability for the Mexican agricultural sector. The administration is currently balancing the need to support domestic farmers—many of whom rely on government subsidies—with the pressure to maintain the competitiveness of high-value exports like avocados, tomatoes, and berries in the U.S. Market.
Navigating the USMCA Review and Trade Tensions
The timing of the leadership change is inextricably linked to the impending review of the USMCA. Under the terms of the agreement, the three nations must undergo a periodic review to ensure the treaty continues to meet its objectives. With the U.S. Administration emphasizing “great deals” and science-based trade rules, Mexico is under pressure to prove its compliance with phytosanitary and labor standards.
Julio Berdegué’s new role as an international coordinator is a tactical move to ensure continuity. In recent months, Berdegué had been a vocal advocate for science and technology-based decision-making
in trade, particularly in response to U.S. Measures affecting Mexican livestock and produce. By keeping Berdegué in a coordinating capacity, Sheinbaum aims to maintain a steady hand in negotiations while López Gutiérrez manages the internal restructuring of the agricultural strategy.
Trade tensions have been exacerbated by disputes over biotechnology—specifically genetically modified (GM) corn—and labor rights. In March 2026, President Sheinbaum sent an initiative to the Senate to strengthen the rights of agricultural day laborers, aiming to ensure that the agro-industry operates under verifiable labor standards to avoid trade sanctions according to legislative reports.
The Screwworm Crisis and Sanitary Challenges
Beyond trade policy, the new Secretary inherits a critical sanitary crisis: the outbreak of the New World Screwworm (NWS). This flesh-eating parasite has caused significant economic damage and led to the U.S. Keeping its borders largely closed to Mexican cattle imports since May 2025.
The fight against the parasite has been a primary focus for Sader and the National Service for Agri-Food Health, Safety and Quality (Senasica). While the administration reported a 57% decrease in active cases as of early January 2026 via official government data, the threat remains a major hurdle for the livestock industry. The continued closure of the U.S. Border to cattle imports represents a significant loss in export revenue and a point of contention in bilateral relations.
López Gutiérrez will need to oversee the completion of the sterile fly plant and the expansion of containment zones in the northeast region to convince U.S. Regulators that the risk has been mitigated. The ability to reopen the livestock trade is not only an economic necessity but a key diplomatic win that could ease tensions ahead of the USMCA review.
Key Pillars of the New Agricultural Strategy
- Agro-ecological Transition: Moving toward sustainable farming practices to reduce chemical dependence and improve soil health.
- Productive Inclusion: Integrating small-scale farmers into formal value chains to reduce rural poverty.
- Phytosanitary Rigor: Accelerating the eradication of the New World Screwworm to restore livestock exports.
- Trade Diplomacy: Utilizing a dual-track approach with a dedicated coordinator (Berdegué) for international negotiations and a Secretary (López) for domestic implementation.
What So for the Global Market
For international observers and trade partners, the appointment of Columba López Gutiérrez signals that Mexico is doubling down on a “social-ecological” model of agriculture. This may lead to more stringent environmental requirements for domestic producers, which could potentially align Mexico more closely with the “Green Deal” standards seen in Europe, while simultaneously attempting to satisfy the pragmatic, science-based demands of the U.S. Department of Agriculture (USDA).
The success of this strategy will be measured by two primary metrics: the ability to maintain export volumes of key produce and the successful reopening of the cattle trade. If the administration can resolve the sanitary crisis and stabilize labor disputes, Mexico will enter the USMCA review from a position of strength.
The transition also reflects a broader trend in the Sheinbaum administration to place women in high-stakes technical roles. By appointing a specialist in agroecology to one of the most contentious portfolios in the cabinet, the President is betting that technical expertise and a focus on sustainability can resolve long-standing political and economic frictions in the countryside.
The next critical checkpoint for the administration will be the formal commencement of the USMCA review process, where the coordinated efforts of Secretary López and advisor Berdegué will be put to the test. Further updates on the status of the New World Screwworm containment are expected from Senasica in the coming months.
