Summary

Informational fragmentation in the Brazilian forestry sector was the starting point of this research, which investigated how data governance impacted analytical capacity, financial risk, and the competitiveness of forest management, through a comparative study between Brazil and Finland. 332 documents were submitted, including 307 CEPEA/Esalq/USP reports (2001–2025) and 25 sectoral reports (Bracelpa, ABRAF, Ibá, 2003–2025), to an automated extraction pipeline based on OCR, text mining, and regular expressions, yielding 13,059 structured records. Sensitivity analysis of Net Present Value (NPV) and lexical sentiment analysis were performed. Only 12.1% of cost records contained the Effective Operational Cost filled out, and none presented a calculable net margin. Uncertainty in input data fluctuated the NPV of a forestry project by more than R$ 20,000/ha, evidencing the distortion of data-driven decision-making when algorithmic sophistication did not replace the quality of the source data. Lexical sentiment analysis confirmed the transition of Brazilian sectoral reports from a statistical to a promotional format. In contrast, the Finnish model demonstrated the viability of integrated governance, with consolidated forest inventory as a pillar of industrial intelligence. The results indicated that strengthening data governance was a prerequisite for the sector’s transition to an evidence-based planning system.

1. Introduction

Currently, data occupies the center of geopolitical and economic disputes, being frequently compared to commodities like oil due to its strategic value. In the context of digital transformations driven by Artificial Intelligence, the ability to process large volumes of data has become an indispensable asset for the competitive advantage of nations and organizations (Provost and Fawcett, 2013; Turban and Volonino, 2013; Brazil, 2025). Just as with raw materials, the value of data lies in its treatment: when integrated into statistical and Machine Learning models, they are transformed into critical information and knowledge for sovereign decision-making.

Despite Brazil possessing historical institutions for systematic data collection, such as the Brazilian Institute of Geography and Statistics and the Informatics Department of the Unified Health System, significant barriers to the integration and reuse of its databases persist. Although the country shows good open data rates, a structural flaw in the reuse pillar is observed: the data is available, but lacks a workable format (Lafuente, 2020). The absence of standardization results in deficient interoperability, keeping informational assets fragmented in institutional silos and increasing analytical latency and operational risk (Belli et al., 2024). Brazil’s digital governance structure has advanced through successive frameworks — from the Marco Civil da Internet (Brazil, 2014) and the General Data Protection Law (Brazil, 2018) to Decrees No. 12.069 and 12.198 (Brazil, 2024) —, however, the practical implementation of interoperability between agencies remains incipient.

This fragmentation manifested itself in a particularly critical way in the forestry sector, where access to operational data is crucial for short- and long-term strategic decisions, both in ecosystem conservation and production efficiency. Data gaps limit the application of Data Engineering and Data Science techniques, tools that are now indispensable for the competitiveness of the private sector and for the development of adaptation plans in the face of extreme climate events. The modernization of the sector depends not only on technological advances but also on governance that integrates technical competence and systemic interoperability, given that analytical effort requires the cross-referencing of heterogeneous sources — foreign trade data, records from regulatory bodies, land registries, and geospatial monitoring platforms — in a context of scarcity of specialized human capital (Silva and Costa, 2024).

From the perspective of operational efficiency, the quality of decisions is intrinsic to the precision of informational inputs; inconsistencies feed the Garbage In, Garbage Out principle, generating uncertainties and financial losses (Turban and Volonino, 2013; Ferrari and Silva, 2017). For the forestry sector, data integrity has been the foundation for the transition from intuitive management to rational management, where information is organized to achieve sustainable objectives with efficiency (Schneider, 2004). The absence of standardization and the lack of articulation between public and private databases introduce latent operational and financial risks, capable of catalyzing failures in management execution and budget overruns. In this sense, data governance acts as a prerequisite for the transition from empirical management to evidence-based decision-making, providing the necessary inputs for models that mimic biological and economic reality (Anderson, 2015).

In contrast, international models such as the Finnish one have demonstrated the viability of integrated governance, in which forest biophysical data are open by law, national inventories are continuously updated by remote sensing, and owners exercise sovereignty over their information through digital platforms (Finland, 2011; Sitra, 2021; Metsäkeskus, 2023). The contrast between the two scenarios highlighted that the efficiency of the bioeconomy depends not only on the gross availability of data but on the existence of digital ecosystems that convert them into intelligible assets. Faced with this scenario, the present research seeks to answer the following question: how do differences in data governance between Brazil and Finland impact the analytical capacity, financial risk, and efficiency of evidence-based forest management? To this end, the work adopts an empirical approach, subjecting real data from the Brazilian forest sector to an automated extraction and structuring pipeline, and confronting the results obtained with the informational maturity of the Nordic model.

2. Material and Methods

2.1. Classification of the research

The research is exploratory in nature and quali-quantitative in approach (Yin, 2015). It combined documentary analysis and comparison of governance models (qualitative dimension) with automated extraction of 13,059 records, lexical sentiment analysis, and Net Present Value (NPV) simulation (quantitative dimension). The methodological design investigated the maturity of data governance in the forestry sector, analyzing the relationships between private market practices, public policies, and State digital sovereignty models. The study focused on the fragmentation of forest management into operational silos (silviculture, harvesting, and logistics) in Brazil and Finland, treating fragmentation as a critical data governance failure and a vector of operational risk.

2.2. Database

The data for analysis were obtained from public and private entity databases, organized into three categories, as synthesized in Table 1.

2.4. Extraction and Storage Pipeline

Due to the heterogeneity of the documents, two complementary extraction “pipelines” were built: one for scanned documents (images) via OCR and another for native PDFs, with direct extraction of text and tables. The selection logic and techniques of each flow are synthesized in Table 3.

The data from both streams were stored in a SQLite relational database with a normalized “schema” (tables: documents, costs, cost composition, technical indicators, and market prices) and in CSV replicas for a “data lake”, allowing structured queries (SQL) and exploratory analyses (Pandas).

2.5. Heuristic Refinement with Artificial Intelligence

The extraction “pipelines” were optimized through iterative heuristic tuning, with the aid of two commercial Artificial Intelligence (AI) models. Table 4 details the role of each tool in the process.

Source: Elaborated by the author (2026)

Text mining sought 28 typical forestry operations (Appendix D) and adjacent quantitative data in sectoral reports, using regular expressions to capture non-tabular information and validate extraction. Sentiment analysis followed Loughran and McDonald’s (2011) lexical frequency classification approach, adapted to the Brazilian forestry sector. A domain lexicon in Portuguese (Appendix B) was built, composed of 16 positive, 17 negative, and 16 ESG terms, iteratively refined to remove ambiguities. The normalized sentiment “score” was calculated as the frequency of terms per thousand words, allowing for comparison between documents. The analysis of three representative documents served as a qualitative indication of the tone change over the period.

2.7. Context of the Finnish “benchmark” and Brazil-Finland comparative matrix

For the comparison between the governance models of Brazil and Finland, a matrix was used that crossed governance indicators (transparency, interoperability, legal compliance, data sovereignty) with competitiveness indicators (digital infrastructure, informational transaction costs, access to certification). The analysis was systematic, considering data sustainability and governance as continuous processes of institutional improvement.

The Finnish “benchmark” is based on the concept of “Fair Data Economy”, which balances technological innovation with state sovereignty and citizens’ digital rights. This framework is enabled by legal and technical instruments, such as the Information Management Act (Tiedonhallintalaki) and the decentralized infrastructure of the Suomi.fi portal (Finland, 2019), which promote open data via APIs. The “MyData” model ensures individual sovereignty over information, allowing control over access to personal data (Sitra, 2021).

The management of Finnish natural resources is integrated by Metsäkeskus, Luke, and Syke. The Forest Information System Act (Metsätietolaki) democratized access to biophysical data of nature (Finland, 2011), separating it from personal data (protected by GDPR). This openness is supported by massive and continuous data collection via LiDAR and satellite imagery for high-precision digital forest inventories.

The Metsään.fi portal allows owners to view a digital twin of their forest and grant access to companies, optimizing the industry’s logistical planning (Metsäkeskus, 2023). Networked harvester machines send real-time data, dynamically updating the national inventory. Table 6 summarizes the structural differences identified between the two forest data governance models.

3. Results and Discussion

Information fragmentation and the hidden cost of data acquisition

Brazil generated and published a large volume of data for multiple purposes. However, the absence of consistent standards in the modeling of these databases and the complex way they were presented severely hindered the analytical reuse of this information, both in the public and private sectors.

In the public sector, institutions such as the Brazilian Institute of Geography and Statistics (IBGE) and CEPEA/Esalq/USP provide a large volume of information, but the architecture of their platforms often hinders large-scale data export. In the private sector, the main difficulty was the way information was made available, with data diluted in sectoral reports or statistical yearbooks of various and regionalized formats.

Most of the effort in this research consisted of locating, extracting, and consolidating these bases, demanding data engineering to transform 332 unstructured documents into permanent information assets. The resulting infrastructure, an SQLite relational database and CSV repository, represented a technical contribution. The cost of this effort was conservatively estimated at over 150 hours of technical work.

Evolution of sectoral reports (2003 – 2025)

National sectoral reports underwent significant changes in content and tone throughout the analyzed period. The documentation went through three distinct phases: in the first (2003–2006), Bracelpa’s statistical yearbooks prioritized quantitative data in charts and tables, favorable for automated extraction. In the second phase (2007–2014), ABRAF’s yearbooks combined technical analyses with tables, charts, and images, resulting in a mixed and partially extractable format. In the third phase (2015–present), Ibá’s reports began to prioritize qualitative content, with texts and images over tables and charts, adopting a predominantly promotional and difficult-to-automate extraction format.

This paradigm shift demanded more aggressive data collection and “data wrangling” techniques, given the absence of public APIs or structured data deliveries. The migration from statistical to promotional reports represented a reduction in the supply of reusable data by the Brazilian private sector, in contrast to the trend of increasing openness observed in Finland.

Sentiment analysis of reports

Lexical sentiment analysis corroborated the transition observed in the reporting phases. The positive “score” grew almost sixfold between 2004 and 2025 (from 3.24‰ to 19.02‰), while the negative one jumped from zero to 10.17‰. Bracelpa’s (2004) zero reflected the purely statistical nature of that document, with neutral technical language. The simultaneous increase in both polarities, with a positive/negative ratio of 1.87:1 in 2025, indicated progressively more emotionally charged language and a deliberate promotional bias. Bracelpa (2004) presented a neutral and statistical profile; ABRAF (2012) reflected a cautious tone, consistent with the economic crisis of the period; and Ibá (2025) exhibited pronounced ESG optimism. From 2015 onwards, reports began to prioritize communication objectives over statistical ones, significantly reducing their usefulness as a source of structured data for quantitative analysis.

Structured data extraction and integrity diagnosis

To quantify the effort of obtaining and the quality of the available data, automated extractions were conducted on monthly bulletins from CEPEA/Esalq/USP (307 bulletins, 2001–2025), sectoral reports from Bracelpa, ABRAF, and Ibá (25 reports, 2003–2025), and cost reports from CNA/Senar (36 documents).

CEPEA Bulletins (307 documents, 2001-2025)

Two complementary “pipelines” were developed: extraction of native tables from PDFs and extraction of prices and percentage variations from narrative text via regular expressions applied to OCR files. The result was the acquisition of structured records, distributed according to Table 7.

Despite the significant volume, the temporal coverage revealed structural discontinuities: from 2009 onwards, CEPEA reports replaced price tables with graphs, making absolute price data by region inaccessible for automated extraction. For the period 2009–2025, it was only possible to extract percentage variations mentioned in the narrative text, useful for trend analysis, but insufficient to feed NPV models that require absolute values.

Sectoral reports (25 documents, 2003 – 2025)

The extraction of reports from Bracelpa, ABRAF, and Ibá required the construction of specific “parsers” for each organization due to variations in table formats, state nomenclature, and document structure. A total of 1,541 records were obtained, as shown in Table 8.

Planted area data dates back to 1980 due to retrospective historical series in ABRAF yearbooks. The “Production” category presents only 9 records because Ibá’s reports provide production data as consolidated national indicators in narrative text, not in standardized tables, hindering automated extraction. In total, the extraction from CEPEA and sectoral sources (Tables 7 and 8) resulted in 13,059 structured records from 332 documents, requiring three distinct Python scripts with over 500 lines of domain-calibrated regular expressions.

CNA/Senar Reports (36 documents)

Of the 36 CNA/Senar documents processed by the same automated “pipeline”, only 33 cost records were extracted. Table 9 presents the fill rate of critical fields for financial analysis.

Revenue (R$/m³)3 of 339,1%

Source: Elaborated by the author (2026) from the SQLite database, with the aid of AI

No records presented a calculable net margin; only 9.1% contained revenue and 12.1% contained Effective Operational Cost (COE), essential variables for viability analysis. In addition to the low fill rate, the data presented artifacts in three dimensions: geographical (region fields corrupted by OCR), temporal (numerical values interpreted as dates), and financial (implementation costs ranging from R$ 989/ha to R$ 29,500/ha). Excluding the extremes, the operational range was between R$ 3,000/ha and R$ 14,000/ha. The technical “pipeline” worked correctly, indicating that the problem lay in the quality and standardization of the source data.

The contrast between the volume of records obtained from CEPEA and from sectoral reports (Tables 7 and 8) and the poverty of financial data from CNA (Table 9) revealed a pattern: Brazil produced descriptive data in reasonable quantity (planted area, exports, macro indicators), but the operational data necessary for financial decisions — costs, revenues, margins — remained practically inaccessible in structured format. This fragmentation was not restricted to CNA reports; a review of 12 academic studies published between 1999 and 2020 revealed that each research collected primary data independently, in different regions and base years, reporting costs in incomparable units. This scarcity was not recent, with Rodrigues (1991) already warning about the non-existence of reliable experimental data for Brazilian forest management. The results of this research demonstrated that this effort did not materialize, and the macroeconomic models that underpinned Brazilian public policies never included forest resources as a relevant variable (Bacha, 2004).

The distortion of data-driven decision

The most revealing aspect of this exercise was the methodological path. Before the present extraction round, an attempt to structure the sectoral reports using the Gemini Flash model (Google) resulted in CSVs with numerically corrupted values, such as eucalyptus areas in scientific notation and numeric fields filled with zeros. Given the impossibility of working with this data, the original quantitative approach of financial viability analysis via NPV was replaced by lexical sentiment analysis, not because it was more relevant, but because it was the only viable technique with the obtained data.

This phenomenon was termed “data-driven decision distortion”, occurring when the research question is shaped by data availability, rather than the other way around. In the Brazilian forest context, an analyst seeking to assess the viability of a project cannot find the necessary data in a structured format; if they have AI tools, they obtain corrupted data; and they often end up needing to reformulate their analysis around what is possible to extract, losing the ability to answer the original question.

Illustrative scenario: NPV and the financial risk of uncertainty

To demonstrate the concrete financial impact of uncertainty in the input data, a sensitivity analysis was built by crossing the two parameters with the greatest variability: the deployment cost and the standing timber price.

Table 10. Sensitivity analysis of NPV (R$/ha) for eucalyptus, 7-year rotation, 8% annual rate.

Implementation costPrice R$ 100/m³Price R$ 130/m³Price R$ 160/m³
R$ 3,000/ha (minimum CNA, excluding artifacts)+1.236+6.014+10.793
R$ 5,500/ha (literature reference)-1.264+3.514+8.293
R$ 14,000/ha (CNA Jaguariaíva/PR)-9.764-4.986-207

Source: Elaborated by the author (2026) from data extracted from Senar/CNA reports, with the aid of AI. Values in R$/ha, rounded

Table 10 revealed that, depending exclusively on the deployment cost data used, the same forestry project would present a positive NPV of R$ 10,793/ha (optimistic scenario) or negative of R$ -9,764/ha (pessimistic scenario), an oscillation of over R$ 20,000/ha. This meant that a Brazilian forestry manager attempting to assess the viability of a eucalyptus project based on publicly available data would not be able to determine, with reasonable confidence, whether the investment would generate profit or loss.

This result empirically validated the “Garbage In, Garbage Out” principle in the forest context: uncertainty in the “inputs” is not a theoretical risk, but a concrete barrier to rational decision-making. The contrast with the Finnish model showed that this uncertainty is not inherent to the sector, but a product of data governance.

The fundamental difference was not in the quantity of data produced — Brazil generated significant volumes — but in the governance architecture that made them usable. The Finnish legal mechanism of separating biophysical data from personal data created an ecosystem where information flows between owners, companies, and government with low friction, while Brazil kept its informational assets in institutional silos and formats that were difficult to reuse. This paradigm difference manifested with greater clarity in the function assigned to the forest inventory: Finland consolidated it as a pillar of industrial intelligence, while Brazil largely confined it to environmental management and enforcement. The result was an informational transaction cost that, in Brazil, made financial analyses unfeasible that would be trivial in the Finnish context.

In summary, the research demonstrated that informational fragmentation in the Brazilian forestry sector constitutes a quantifiable financial and operational risk. The automated extraction of 13,059 records from 332 documents demanded over 150 hours of technical work, but revealed a critical asymmetry: descriptive data were obtained in a reasonable quantity, while elementary financial variables presented filling rates below 12.1% for the Effective Operational Cost, and no calculable net margin. Sensitivity analysis indicated that uncertainty in input data can fluctuate the NPV of a forestry project by more than R$ 20,000/ha, compromising the return on investment assessment. The phenomenon of “data-driven decision distortion” was observed, where the lack of data quality forced the reorientation of financial viability analysis towards sentiment analysis. This analysis, in turn, confirmed the transition of sectoral reports from a statistical format to a predominantly promotional one, reducing their analytical utility. The comparative study with Finland highlighted that the central issue is not the volume of data, but the governance that makes it usable, with the Finnish model promoting a low-friction information ecosystem, in contrast to Brazilian institutional silos. Strengthening data governance, including standardization and API access, is a prerequisite for the Brazilian forestry sector’s transition to evidence-based planning.

4. Conclusion

This research investigated how data governance differences between Brazil and Finland impact analytical capacity, financial risk, and the efficiency of evidence-based forest management. It was found that informational fragmentation in the Brazilian forest sector constituted a significant barrier, requiring considerable effort to extract and structure 13,059 records from 332 documents. However, a critical asymmetry was observed in the findings: while descriptive data were obtained in a reasonable quantity, essential financial variables, such as Effective Operational Cost, showed fill rates below 12.1%, with no calculable net margin. Sensitivity analysis demonstrated that uncertainty in this input data could fluctuate the Net Present Value of a forestry project by more than R$ 20,000/ha, compromising the determination of return on investment. This scenario materialized the phenomenon of data-driven decision distortion, where the lack of quality in informational inputs forced the reorientation of financial feasibility analysis towards lexical sentiment analysis. This, in turn, confirmed the transition of Brazilian sectoral reports from a statistical format to a predominantly promotional one, reducing their analytical utility. In contrast, the Finnish model demonstrated the viability of integrated governance, with consolidated forest inventory as a pillar of industrial intelligence, facilitating data flow and reuse.

The study’s main contribution lies in the empirical demonstration that informational fragmentation in the Brazilian forestry sector is not merely a technical limitation, but a quantifiable financial and operational risk. Strengthening data governance, which includes standardizing publication formats, creating public APIs for sectoral data, clearly defining roles in the information custody chain, and investing in specialized human capital, is a prerequisite for the sector’s transition to an evidence-based planning system. Limitations acknowledged include that the sentiment analysis was based on a reduced sample of documents and that the extraction results reflected the sources and tools available during the study period. For future studies, it is suggested to replicate the research with expanded corpora, build standardized forestry data repositories, and evaluate the economic impact of adopting open data standards in the sector.

Consumer Journey in the Decision to Purchase Infoproducts in the Digital Environment

The expansion of e-commerce and technological transformation have driven the need to understand consumer behavior regarding infoproducts, whose perceived experience has become crucial for professional development. The study aimed to analyze the factors that influenced the purchase decision of infoproducts in the digital environment, considering the stages of the consumer journey. An applied, quantitative, and descriptive research was conducted through a field survey with 100 consumers from Serra Gaúcha. Data collection occurred via a structured questionnaire, using non-probabilistic sampling. The results revealed a qualified audience with strong “mobile-first” behavior. It was found that the availability of detailed information and social approval were the main attraction triggers in the pre-purchase phase. In the transactional and subsequent stages, the minimization of operational friction, the agility of immediate access, and system security proved crucial for conversion and satisfaction, although gaps in human support efficiency were identified. Retention was based on the trust generated by positive past experiences, overcoming the price factor. It was concluded that the infoproduct consumer journey operates as an integrated system, requiring alignment between technological infrastructure, content curation, and support humanization to ensure engagement.

Aggregate non-payment in the Brazilian financial system is a crucial indicator of credit risk, the prediction of which is regulated by CMN Resolutions n.° 4.557/2017 and 4.966/2021 for the prospective measurement of expected losses. Aggregate non-payment was modeled and predicted using the SARIMAX model, projecting its trajectory until December 2026 under optimistic, base, and pessimistic scenarios. 164 monthly observations (July/2012 to February/2026) and macroeconomic variables such as unemployment, Selic, IPCA, IBC-Br, and household debt were used. The specification with contemporaneous variables was selected based on information criteria and coefficient stability, and residual diagnostics confirmed statistical adequacy, with a MAPE of 3.12%. Historical non-payment ranged between 4.33% and 7.64%. The estimation identified unemployment (β = 0.2534; p < 0.001) and Selic (β = 0.2128; p < 0.001) as the main positive determinants, with strong temporal persistence (AR(1) = 0.8965). Selic showed increasing correlation with non-payment (r = 0.62 at lag 12), while unemployment demonstrated a contemporaneous effect (r = 0.33). Projections indicated non-payment between 6.30% and 7.98% in December 2026, with a range of 1.68 percentage points, highlighting direct implications for provisioning in financial institutions.

Combating Commercial Electric Energy Losses Using a Time Series Model

Commercial losses of electric energy represented one of the main challenges for distributors, directly impacting economic sustainability and supply quality. The efficiency of time series models, focusing on exponential smoothing techniques, was evaluated in forecasting billed consumption of consumer units, to support the identification of deviations associated with non-technical losses. Historical data of monthly consumption from an electric energy distributor in Brazil were used, segmented by behavior profiles (stationarity, trend, and seasonality). Simple exponential smoothing models, Holt, and Holt-Winters (additive and multiplicative) were applied, compared to a traditional moving average. The Mean Absolute Percentage Error (MAPE) was the evaluation criterion. Additionally, the ETS approach was employed for automatic model selection and residual diagnostic tests, such as Ljung-Box and autocorrelation function analysis. The results demonstrated that more robust models showed a greater capacity for adaptation to the series’ characteristics and lower error, with a highlight on superior performance in scenarios with trend. For seasonal series, the ETS model showed a greater capacity for adaptation to transitions. It was concluded that the use of more structured time series models contributed significantly to the improvement of forecast accuracy and offered relevant analytical support for the identification of commercial losses and the optimization of operational and commercial processes in the electric sector.
