Study links education, monitoring to lower abandonment in Maceió: full analysis
A new study from Maceió, Brazil, suggests that companion animal abandonment during disaster-driven relocation can be reduced when rescue and adoption efforts are paired with systematic monitoring and environmental education. The research examines the long-running displacement crisis tied to ground subsidence from rock salt mining in Maceió and finds that abandonment remained substantial, but declined over the 2020-2024 intervention period, with the trend shifting more clearly in 2023 as educational activities intensified.

The backdrop is a major urban environmental disaster. Ground instability linked to decades of rock salt extraction forced the relocation of more than 55,000 residents from several Maceió neighborhoods, according to the study, while broader reporting has described the crisis as affecting far more people across the city. Braskem says it halted rock salt extraction in May 2019 and later moved to close and backfill wells, while legal and political scrutiny has continued: in November 2024, Brazil’s federal police indicted 20 people in connection with the catastrophe, according to the AP.

The study’s most striking early figure comes from the relocation phase before the intervention matured. Using prior local data, the authors note that among 567 animals recorded in affected households from March 2018 to September 2020, only 245, or 43.2%, were relocated; the rest were abandoned or escaped. To address that, the Federal University of Alagoas-backed Integra Animal project combined rescue and sheltering, clinical and surgical support, adoption campaigns, and school-based outreach framed around responsible pet parentship and One Health.

Across October 2020 to December 2024, the project sheltered 1,826 animals, including 1,147 classified as abandoned. Cats made up the large majority of abandoned animals, and 75.8% were younger than 1 year. The highest abandonment burden was seen in Pinheiro and Bebedouro. The paper reports a decreasing correlation in abandonment over time, while 864 animals were adopted during the study window. Among animals identified as belonging to families, only 9 of 159 were reclaimed, a low reunification rate that highlights how quickly displacement can fracture the bond between families and animals when planning is incomplete.

The educational component appears central to the authors’ argument. In 2023, the Alagoas public security department partnered with the university group behind Integra Animal on an awareness and action plan against mistreatment. That same year, 30 students at a nearby public school took part in seven classes on mistreatment, legal protection, welfare, environmental impacts, and responsible pet parentship. Students then organized an adoption campaign that resulted in 12 adoptions. The authors say the broader reversal in abandonment trends from 2023 coincided with strengthened educational activity, though the design supports association rather than proving causation.

A related 2025 analysis in BMC Veterinary Research, drawing on the same Maceió context and Integra Animal data, reached a similar conclusion: educational and community-based initiatives played a “decisive role” in reversing abandonment trends and argued for institutional frameworks, systematic monitoring, and state-supported education programs. That follow-up paper also documented 52 mistreatment and abandonment reports in affected neighborhoods in 2023, involving 109 animals, mostly dogs, through the state hotline system.

Why it matters: For veterinary professionals, the study reinforces that companion animals need to be built into disaster relocation planning from the start, not handled as an afterthought. The practical implications are familiar but often under-resourced: field identification, transport planning, temporary housing that accepts animals, triage and sterilization capacity, reunification systems, and communication that helps pet parents understand their options before evacuation deadlines hit. The Maceió experience also points to a broader One Health lesson: abandonment during displacement can become both an animal welfare issue and a public health, shelter capacity, and community confidence issue.

What to watch: The next question is whether these findings translate into permanent policy. The authors call for sustained public policies around responsible pet parentship, sterilization, enforcement, and monitoring in crisis-affected urban areas. Given the continuing fallout from the Maceió mining disaster, veterinary teams, municipalities, and civil defense agencies will be worth watching for signs that pet-inclusive relocation protocols become formal practice rather than project-based exceptions.
