The report finds a widespread failure in the Mexican flour industry to adhere to mandatory fortification laws, with only 7% of tested pre-packaged flours meeting both nutrient level and iron-compound requirements. Maize flour, which holds 72% of the cereal market share, is particularly critical as no tested brands were adequately fortified. The study highlights that even government-distributed flours for vulnerable populations, such as those from Diconsa and DIF Chiapas, fail to meet legal standards. The authors argue that the industry's negligence exacerbates 'hidden hunger' and anemia, and they call for the Mexican government to implement stricter monitoring and sanctions.

The report finds that only 7% of tested flour products in Mexico are adequately fortified, with maize flours performing particularly poorly. It highlights a systemic failure by the food industry to comply with regulation NOM-247-SSA1-2008, including failures in government-funded social welfare programmes like Diconsa and DIF Chiapas.

The report proposes eight strategic policy axes for Mexico City to transition toward a sustainable urban model: Transit-Oriented Development, territorial delimitation, public transport integration, mixed land use, small blocks, non-motorized mobility, automobile use control, and recreational public spaces. It establishes quantitative benchmarks for 2018, 2024, and 2030 to reduce car dependency and improve air quality and public health. Key recommendations include implementing a single payment card for integrated transport, establishing strict urban growth boundaries, and promoting 'urban recycling' to create walkable neighborhoods.

The document presents a comprehensive dataset of iron and zinc concentrations in wheat and corn flours, including fortified and non-fortified samples. It details the brand, producer, and specific iron sources (such as ferrous fumarate, ferrous sulphate, and electrolytic iron) for products across multiple Mexican states and imported brands.

During the second half of December 2022, monarch butterfly colonies in Mexico occupied 2.21 hectares of forest, representing a 22% decrease from the 2.84 hectares recorded in 2021. Of the 11 colonies identified, six (1.52 ha) were located within the Monarch Butterfly Biosphere Reserve (MBBR) and five (0.69 ha) were outside the reserve. The largest colony (0.797 ha) was found in Ejido El Rosario, while the smallest (0.004 ha) was in Ejido El Potrero. The report identifies climate change, forest degradation in Mexico, and the decline of milkweed in the United States as primary threats to the species.

During the second half of December 2023, nine monarch butterfly colonies in Mexico occupied a total of 0.9 hectares of forest, representing a 59.3% decrease from the 2.21 hectares recorded in 2022. Five colonies (0.273 ha) were located within the Monarch Butterfly Biosphere Reserve, while four (0.627 ha) were outside. The largest colony was found in the San Antonio Albarranes ejido (0.346 ha) and the smallest on Federal Property (0.003 ha).

During the second half of December 2021, 10 monarch butterfly colonies were recorded in Mexico, occupying a total of 2.835 hectares of forest. This represents a 35% increase from the 2.10 hectares recorded in 2020. The colonies were distributed equally between Michoacan and the State of Mexico, with 2.174 hectares located inside the Monarch Butterfly Biosphere Reserve (MBBR) and 0.661 hectares outside of it. The largest colony was found in the Sierra Campanario Sanctuary at 1.187 hectares, while the smallest was in the Lomas de Aparicio Sanctuary at 0.003 hectares.

During the 2024-2025 overwintering season, monarch butterfly colonies in Mexico occupied 4.42 acres of forest, marking a 99% increase from the 2.22 acres recorded in 2023-2024. Eight colonies were identified: three within the Monarch Butterfly Biosphere Reserve (MBBR) covering 3.01 acres and five outside the MBBR covering 1.42 acres. The largest colony was found in ejido El Rosario, Michoacán (2.46 acres), while the smallest was in San Andrés (0.005 acres).
