The Open Wound: Deforestation in Mato Grosso from Fonseca to the Present Day
A journey through time exploring the transformation of Brazil's forests from the 19th century expeditions to today's environmental challenges

Introduction: A Journey Through Time in the Lost Forest
Between 1875 and 1878, physician and naturalist João Severiano da Fonseca undertook an epic expedition through Brazil, recording his impressions in the work "Viagem ao Redor do Brasil". While he described landscapes and populations, he could hardly imagine the radical transformation that one of the regions he traveled through, Mato Grosso, would undergo in the following decades. Today, this state is simultaneously one of the country's largest grain producers and one of the epicenters of deforestation in the Legal Amazon.

of deforestation occurs within 50km of roads 6
Fonseca's journey represents a symbolic starting point for understanding the long history of transformation of the Brazilian natural landscape, a process that evolved from localized exploitation to environmental change on a continental scale, with consequences that extend to the entire planet.
"The loss of forest is not merely the removal of trees; it is the erosion of a vital system that regulates the climate, shelters immeasurable biodiversity, and sustains cultures."
Mato Grosso in Fonseca's Work: A Portrait of a World in Transformation
João Severiano da Fonseca's expedition took place during a crucial period in Brazil's history. The independent country was directing its efforts to integrate and explore its vast interior, a movement that would gain even more strength in the following century. "Viagem ao Redor do Brasil" therefore serves as a valuable record of the state of the natural landscape in a pre-industrial acceleration era.
Although the specific records about Mato Grosso in his work require direct consultation of the bibliographic material 3 , the historical context allows us to infer that Fonseca witnessed the beginnings of anthropogenic pressure on the forest. At that time, human intervention was punctual, limited by technology and logistics, but already signaled the start of a process that would intensify dramatically.

Timeline of Deforestation in Mato Grosso
Fonseca's Expedition
João Severiano da Fonseca travels through Brazil, documenting the natural landscape in its relatively preserved state.
Initial Settlement
Limited deforestation primarily for subsistence agriculture and small-scale resource extraction.
Road Construction & Colonization
Government programs build highways like BR-163, opening the region to large-scale settlement and agriculture.
Agricultural Expansion
Rapid expansion of cattle ranching and soybean cultivation accelerates deforestation rates.
Control Efforts
Mato Grosso implements pioneering deforestation monitoring and control program 8 .
Ongoing Challenges
Mato Grosso remains both an agricultural powerhouse and deforestation hotspot with fluctuating rates based on policy and economic factors.
The Multiple Faces of Destruction: What Drives Deforestation
Deforestation is defined as the complete and permanent disappearance of forests, mostly caused by human activities 1 . In Mato Grosso, this process accelerated in the last decades of the 20th century, driven by a development model that prioritizes the conversion of forests into commodities.
Expansion of monocultures, especially soybeans, on large properties 8 . Intensive land use leads to biodiversity loss and soil alteration.
Legal and illegal extraction of noble woods, which often serves as the first step towards definitive occupation 7 . Degrades the forest, making it more vulnerable to fires and subsequent total clearance.
In addition to these factors, large-scale projects such as the construction of hydroelectric dams also contribute to forest loss, not only by flooding areas but by attracting workers and opening roads, facilitating the disorderly occupation of the territory 2 .
Beyond Fallen Trees: The Environmental and Social Impact
The consequences of deforestation go far beyond the altered landscape. It triggers a cascade of negative effects:
Water Cycle Disruption
The "flying rivers" – moisture currents formed by forest evapotranspiration – are essential for rainfall in much of South America. The reduction of forest cover weakens this mechanism, potentially leading to prolonged droughts both in the region and in other areas of the continent .

The Mato Grosso "Experiment": A Case Study in Deforestation Control
The complexity of deforestation requires equally complex solutions. Mato Grosso was the stage for a pioneering control program in the late 1990s and early 2000s, which functioned as a large-scale experiment on the effectiveness of state action.
Methodology: Data-Based Enforcement
The program, executed by the State Environmental Foundation (FEMA-MT), adopted an innovative approach for the time 8 :
Satellite Detection
Illegal deforestation was initially identified through the analysis of satellite images (such as those from LANDSAT), which allowed locating clearings with precision.
Field Inspection
Teams of technicians were sent to the identified locations. Using global positioning systems (GPS), they located the deforestation and the headquarters of the responsible property.
Legal Action
Property owners were notified, and documentation was forwarded to the Public Prosecutor's Office for legal action. The system allowed offenders to contest, but the burden of proof fell on them.
Results and Analysis: Repression Works, but with Nuances
The results of this "experiment" were remarkable. Deforestation rates in Mato Grosso decreased after the program began, while they continued to increase in other parts of the Legal Amazon 8 . Data analysis revealed crucial insights:
FEMA data showed that the vast majority (about 72% of the deforested area in a biennium) consisted of clearings larger than 100 hectares, indicating that large landowners were the main responsible for total deforestation 8 . This allowed enforcement, with limited resources, to have a significant impact by focusing on large infractions.
The program created a new regulatory "environment," progressively convincing landowners to adapt their behavior due to the real risk of punishment 8 .
Distribution of Deforested Area Sizes in Mato Grosso (2000-2001 Biennium)
| Clearing Size | Percentage of Total Deforested Area |
|---|---|
| Up to 100 hectares | 36% |
| 101 - 500 hectares | Part of remaining 64% |
| 501 - 1,000 hectares | Part of remaining 64% |
| Above 1,000 hectares | Part of remaining 64% |
| > 100 hectares (aggregate) | 64% |

Key Insight: This case demonstrates that deforestation is not an uncontrollable process. Political will, combined with the use of technology and consistent law enforcement, can effectively contain its speed.
The Toolkit for Combating Deforestation
The success of the program in Mato Grosso highlighted the importance of a set of tools and policies for conservation. These solutions range from technology to market mechanisms.
Satellite Monitoring
Allows near real-time detection of deforestation and heat spots, being fundamental for enforcement and quick action.
Field Enforcement
Action by environmental agents to verify infractions on site, notify offenders, and embargo illegally deforested areas.
Environmental Certifications
Seals such as FSC (for wood) and RSPO (for palm oil) assure consumers that products come from sustainable sources, rewarding good practices in the market 5 .
Indigenous Land Protection
Indigenous territories are proven effective barriers against deforestation, preserving the forest and the ways of life of native peoples 6 .
Robust Public Policies
Creation and implementation of plans like PPCDAm (Action Plan for Prevention and Control of Deforestation in the Legal Amazon), which coordinate actions between different government levels.
Economic Incentives
Financial mechanisms that reward forest conservation and sustainable practices, making preservation economically viable for landowners.

Conclusion: Between Fonseca's Past and an Uncertain Future
The journey of João Severiano da Fonseca through 19th century Brazil reminds us of a more intact landscape, a natural heritage whose integrity was beginning to be tested. The Mato Grosso of today is the result of economic, political, and social choices made over generations.
The agricultural frontier that advanced over the forest brought economic prosperity for some, but at a deeply alarming environmental and social cost.
The future of the forest in Mato Grosso and throughout the Amazon hangs in the balance. Scientists warn of a tipping point, where deforestation, combined with climate change, could trigger an irreversible process of savannization (dieback) of the forest . Studies show that the impact of deforestation is not restricted to the cleared areas; for every 100 trees lost, another 22 may die due to changes in rainfall patterns, a devastating "domino effect" .
Critical Threshold
Scientists estimate that if deforestation reaches 20-25% of the original Amazon forest cover, it could trigger an irreversible tipping point leading to large-scale savannization .
Progress toward estimated 25% tipping point
The Way Forward
However, the case of the control program in Mato Grosso proves that the trajectory can be altered. The solution will require a paradigm shift: we must value the standing forest more than the cleared forest.
- Conscious consumption
- Consistent public policies
- Economic incentives for conservation
- Respect for the knowledge of forest peoples
The journey to preserve Mato Grosso and the Amazon is far from over, and its final destination will be decided by the actions – or inactions – of the present.
