Paraná court backs two IBAMA forest cases that used MapBiomas Alerta

Paraná's Court of Justice kept a regeneration injunction in 2021 and upheld a repair order in 2024 for clearings of 49.41 ha and 17.40 ha that IBAMA pursued with MapBiomas alerts.

  • 2 for an organization

    IBAMA acted on two clearings found with alerts, and the court kept a regeneration injunction for 49.41 ha and upheld a repair order for 17.40 ha.

  • Not rated society

    The decisions order regeneration and repair, but neither reports whether the forest grew back.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

Status
Reported benefit.
Evidence

foundstudiedreportedclaimed

Two independent court documents support the benefit.

The system’s part
Not isolated. Neither decision compares enforcement with and without the alerts or tests their accuracy. In 2019 IBAMA called the alert experimental and relied on its own field measurement, which gave a larger area than the alert. MapBiomas states that analysts validate each alert on Planet images and that a supervised Random Forest classifier refines its outline.

AI system

Workflow

IBAMA staff used MapBiomas alerts with multitemporal satellite analysis to find clearings. Agents measured one clearing in the field with GPS and corrected the area in their notice. State prosecutors sought injunctions and repair orders on IBAMA's findings.

Follow-up

Conditions for replication

Field measurement must confirm the area, since one alert understated a clearing. Courts must accept IBAMA's notices and comparative satellite images as proof of the damage.

Entry details

Sector

Environmental enforcement: Atlantic Forest clearing.

Purpose

MapBiomas built MapBiomas Alerta to compile, validate and refine deforestation alerts from detection systems across Brazil and to publish each confirmed clearing with a report.
