CAR · PRA · GIS Evidence · Amazon
Environmental regularisation is one of the most pressing legal obligations facing rural landholders in Brazil. The Cadastro Ambiental Rural (CAR) and the Programa de Regularização Ambiental (PRA) both require precise spatial documentation, land-cover history, vegetation remnant evidence, APP delineation, that most producers cannot produce alone and that most agronomists and lawyers cannot produce without dedicated GIS support.
I provide that support. Working from Acre, with active experience across Rondônia and southern Amazonas, I produce the spatial evidence layer that CAR/PRA processes require, using MapBiomas, PRODES and field data to build documentation that holds up under regulatory and judicial scrutiny.
The spatial evidence problem
The Forest Code (Lei 12.651/2012) requires rural properties to document their boundaries, quantify vegetation remnants and map permanent preservation areas. Where deforestation occurred after 2008, PRA requires a restoration commitment backed by spatial evidence of what existed before, and what exists now. That evidence must come from a defensible spatial methodology.
In practice, CAR registration is frequently completed with imprecise or unverified boundary data. Property limits are drawn from memory or transferred from paper deeds with no georeferencing. Vegetation remnants are estimated rather than classified. APPs, the legally protected strips along watercourses, hilltops and steep slopes, are often not delineated at all, or delineated incorrectly using coarse national datasets that do not reflect actual property conditions.
When a CAR registration reaches the PRA stage, or when it is challenged in a regulatory inspection, credit application or legal proceeding, the weakness of the original spatial evidence becomes a serious problem. Correcting it retroactively, under legal or commercial pressure, is significantly harder and more expensive than producing defensible evidence from the outset.
The gap exists because producing rigorous spatial evidence requires satellite data analysis, GIS expertise and knowledge of Brazil's specific regulatory datasets, a combination that is rarely available within the property owner's own circle of advisors. Agronomists and environmental lawyers may understand the regulatory requirement; they generally do not have the tools to meet it alone.
What Forestana delivers
Every regularisation engagement produces a documented, reproducible spatial evidence set, from boundary review through to the producer-facing summary that makes the technical work legible to the people who will act on it.
Property boundary review and georeferencing
Verification and correction of property perimeter data against cadastral records, SICAR files and satellite-visible features. Output: a validated boundary polygon in the required datum and format.
Land-cover history from MapBiomas
Annual land-cover classification from 1985 to the present at 30 m resolution (MapBiomas Collection 8), extracted for the specific property boundary. Documents what was native vegetation, when deforestation occurred and what regeneration has taken place since.
Deforestation detection with PRODES
Cross-referencing property history against PRODES annual deforestation increment polygons (INPE) to establish the date, extent and legal status of any clearings, the critical step for determining PRA obligations under the Forest Code's 2008 baseline.
APP mapping, river buffers, hilltops, slopes
Delineation of Permanent Preservation Areas using property-specific hydrography from ANA (Otto-coded) and DEM-derived topographic analysis. Buffer widths applied according to Forest Code specifications for each watercourse type.
Compliance maps for legal and agronomic review
Cartographic plates showing the full compliance picture: property boundary, land cover by year, APP extent, legal reserve, consolidated areas and areas under restoration obligation. Formatted for use in regulatory filings and legal proceedings.
Producer-facing summary report
A plain-language summary in Portuguese, translating the technical spatial analysis into decisions the property owner can understand and act on, what the property's situation is, what obligations apply and what the path to compliance looks like.
Who this is for
Environmental regularisation brings together rural producers, technical advisors and legal professionals, each needing something slightly different from the spatial evidence layer.
Rural producers
Rural credit from public banks (Pronaf, ABC Mais) increasingly requires a clean CAR and documented compliance status. Land transactions and inheritance processes demand the same. Producers need documentation that is credible to lenders, registries and inspectors, not just a form that has been submitted.
Agronomists
Registered agronomists (engenheiros agrônomos) are frequently the professionals responsible for signing off on CAR/PRA technical files. Where GIS analysis is needed but not available in-house, Forestana provides the spatial evidence layer, with full methodology documentation, that the agronomist can rely on and stand behind professionally.
Environmental lawyers
Environmental litigation and administrative proceedings frequently turn on spatial questions: when did deforestation occur? What was the vegetation cover in a given year? Where is the APP boundary? Forestana provides court-ready spatial evidence with documented sources, methodology and reproducible outputs, the kind of technical backing that survives cross-examination.
Regional expertise
Acre, Rondônia and southern Amazonas are three of the states where the distance between formal regularisation requirements and the capacity to meet them is greatest. These are regions of recent agricultural frontier expansion, complex tenure history, significant indigenous territory overlap and limited access to qualified GIS professionals.
They are also the regions where the Amazon-specific data environment, cloud cover, PRODES classification boundaries, FUNAI territory overlaps, outdated hydrographic data, is most consequential. A regularisation file produced without understanding these local data conditions will have gaps that a well-resourced adversary will find.
Through Forestana and ACS Consultorias, I have worked on regularisation and geotechnology in these regions since 2021. The institutional relationships, data familiarity and field experience that come from working within the landscape, not remotely at it, are part of what I bring to every engagement.
Acre
Home state and primary operational base. Direct institutional relationships with SEMA/AC, IMAC, FUNAI regional offices and CPI-Acre. Active ACS Consultorias network across municipalities.
Rondônia
High-priority state for CAR/PRA work due to frontier deforestation dynamics and significant rural property portfolio. Active project experience and partner network.
Southern Amazonas
Complex tenure landscape with large indigenous territory footprint and significant regularisation backlog. Engaged through partner networks and Envreg pipeline development.
Envreg, scaling this workflow
Individual regularisation engagements are one part of a larger effort. Envreg is the systematic service I am building to handle environmental regularisation at scale, combining the same GIS evidence pipelines with structured legal and agronomic partner workflows, designed for the volume of properties that need attention across the Brazilian Amazon.
Envreg
Envreg is in active development. If you are a regional agronomist, environmental lawyer, fintech operator or investor who works with the regularisation challenge at scale, the Envreg page has more detail on the partnership model and what the platform will deliver.
