Challenging the Environmental History of the Cerrado: Science, Biodiversity and Politics on the Brazilian Agricultural Frontier
Bibliographic record
Abstract
This article presents an overview of the environmental history of the Brazilian Cerrado, its environmental characteristics and the processes related to the historical change in the landscapes of this endangered ecosystem. It highlights competing classifications of the Cerrado, the role of politics in establishing them, and the environmental consequences of such classifications. More than just describing an environment, classifying an ecosystem is a political process that involves complex socio-environmental interactions. The sources used points out the different attempts to get to know and "conquered" the Cerrado, bringing together interdisciplinary perspectives from a variety of actors and institutions. Historiographic challenges go beyond environmental descriptions in that the socio-environmental interactions that made up this unique ecosystem are equally complex. This paper’s conclusions reinforce the interdisciplinary role of environmental history in the study of ecosystems and the complex relationship between culture and nature.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
