Impact Of a Low-Income Informal Settlement in a Headwater Area at High-Risk Of Erosion in Brazil
Bibliographic record
Abstract
The largest remaining area of preserved Atlantic Forest in the Belo Horizonte City (Minas Gerais, Brazil) protects many headwaters and watercourses.Among them, the Macacos stream is considered the most preserved with high water quality.However, since 2013 this region has suffered an intense and disorderly of informal settlement process by low-income communities, which resulted in a progressive loss of the original vegetation.Due to the lack of vegetation, this area became prone to erosional process as demonstrated by the topographic analysis.The Normalized Difference Vegetation Index (NDVI) demonstrated the great impact of the settlement process over the vegetation, ranging from 1 to 0. Besides, this eroded area has faced the loss of biodiversity as estimated by the richness and Shenon's index as well as the invasion by exotic species as Brachiaria sp and Typha domingensis.Also, the erosional process in this hilly site resulted in the accumulation of high level of sediments in the Macacos stream.Therefore, the restoration of headwaters and riparian sites aiming at soil stabilization and vegetation restoration is highly recommended.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
