Meanwhile, deforestation in the region continues, with the planned zone accounting for 76.5% of deforestation in the three states between 2018 and 2022, warns an article published in the journal Perspectives in Ecology and Conservation.
They used official data based on remote sensing to analyze an area in southern Amazonas, eastern Acre, and northwestern Rondônia measuring some 454,000 square kilometers (km2), about the size of Sweden, the fifth-largest European country. Sometimes referred to as the new deforestation arc, the area contains 32 municipalities and has 1.7 million inhabitants. Planning and organization of the SDZ is in progress.
Deforestation rates in Legal Amazonia, an area of more than 5 million km² comprising nine Brazilian states (Acre, Amapá, Amazonas, Maranhão, Mato Grosso, Pará, Rondônia, Roraima, and Tocantins) created by federal law to promote environmental protection and regional development, rose gradually in the last decade, surpassing 10,000 km2 per year and reaching 13,038 km2 in 2021, the highest level since 2006, according to PRODES, INPE’s Amazon Forest Satellite Monitoring Service. However, after four consecutive years of high rates, annual deforestation fell 22% to 9,001 km2 between August 2022 and July 2023.
In an analysis of deforestation rates by land tenure, the researchers show that they were highest and rising on private property but accelerated alarmingly in conservation units between 2018 and 2022.
Public land, a large proportion of the proposed SDZ, including extractive reserves and Indigenous territories, was also under growing pressure. In 2021, for example, 64% of deforestation occurred on public land.
For the authors, the lack of environmental impact studies and socioenvironmental policies to protect traditional communities is a cause for concern, raising doubts about the viability and sustainability of the project.
The idea of establishing the SDZ originally focused on soybean growing, Chaves recalled, and for this reason it was at one time referred to as a “northern MaToPiBA.” Almost 12% of the nation’s soybean crop is grown in the area known as MaToPiBa, a portmanteau of Maranhão, Tocantins, Piauí, and Bahia, parts of which form another agricultural frontier and are seeing an increase in conversion of native vegetation into pasture and cropland.
When Agência FAPESP asked the Ministry for Integration and Regional Development to comment on the plan, it pointed them to SUDAM, which has not replied to the request.
In absolute terms, deforestation increased in all land tenure classes, but the acceleration was most intense in conservation units, especially since the SDZ project was announced in 2018. In land reform settlements (assentamentos rurais), the highest level was 625.56 km2 in 2021, 83.34% above the 2012-20 average (341.20 km2).
The study used data from PRODES, which has consistently maintained its methodology since 1988 and is considered the most accurate source for estimates of annual deforestation rates in the Amazon. This was combined with geographic information and data from the Rural Environmental Register (CAR) and the Land Management System (SIGEF).
All landowners are required to register with the CAR, which is supposed to ensure compliance with the Forest Code. The process is essentially self-declaratory. Landowners are also required to register properties with the Land Management System (SIGEF) administered by the National Institute for Colonization and Agrarian Reform (INCRA) in order to obtain title, financing, and permits for developments such as hydroelectricity or mining projects.
For penultimate author Felipe Gomes Petrone, a master’s candidate and remote sensing researcher at INPE, “Merely defining rural development zones without socioenvironmental impact assessments and public policies can do more harm than good to the agri-environmental sector.”
According to Adami, “Farmers need to be strong allies of environmental protection because it raises yields and leads to many other improvements via conservation of natural factors such as rain, nutrient cycling, pollination, and so on. Disruption of climate regulation and the useful water cycle for agricultural production in important producer states can lead to losses worth billions.”
The authors advocate diversified agricultural production in the SDZ, with appropriate environmental safeguards, strategies to add value to local production, and valorization of the standing forest.
