Mexico continues to face a complex landscape of environmental and fiscal challenges. Budgetary projections for 2027 indicate a stark disparity in resource allocation, with climate change adaptation and mitigation funds expected to decrease by 24.6% from 2026 levels, falling to approximately 160,120.9 million pesos. This trend highlights a heavy fiscal priority toward the energy sector; for every peso of projected public spending in 2027, only about 1.5 centavos are allocated to climate change, while Pemex is projected to receive 678,662.7 million pesos.

In contrast to these federal budget cuts, the government is driving over 180 billion pesos in water infrastructure projects. Specific allocations include 80 billion pesos for 17 strategic projects, 20 billion pesos for the sanitation of the Atoyac, Lerma-Santiago, and Tula rivers, and 3 billion pesos for the recovery of the Tijuana River. Conagua is currently managing 24,000 works across 2,183 municipalities. Data from INEGI indicates that piped water access in homes rose from 77.6% to 82.4% between 2020 and 2025, benefiting approximately 7 million more people.

Beyond water management, the government is addressing environmental degradation through the ‘Aguacate Cero Deforestación’ mechanism, which prohibits the export of avocados grown in deforested areas to combat illegal logging. To support the industry, President Claudia Sheinbaum has signed agreements with the Association of Avocado Producers and Packers Exporters of Mexico (APEAM) to strengthen security, sanitation, and labor conditions, ensuring environmental traceability. Additionally, authorities are intensifying efforts against wildlife trafficking, reporting the seizure of approximately 20,000 flora and fauna specimens at airports. Recent reports also highlight a 111% increase in funding for science and technology research.
