Historical Roads and Deforestation Spillovers in the Brazilian Amazon, 1968-1993

LBA-ECO LC-24 data spans 1968 to 1993 for the Legal Amazon region. It provides evidence of spatial spillovers from road investments, showing deforestation rises in census tracts without roads but within 100 km of a tract with a new road. The dataset supports a complete evaluation of infrastructure expansion impacts on habitat conversion.

Use Cases

• Modeling spatial spillover effects of roads on deforestation based on distance thresholds.
• Evaluating infrastructure development policies in the Brazilian Amazon using historical road data.
• Benchmarking land cover change models against a 25-year historical record.

Strengths

• Temporal coverage spans 25 years (1968-1993).
• Cross-platform presence on Data.gov and NASA EarthData indicates recognized importance.
• Dataset is associated with a specific research finding on spatial spillovers within 100 km.

Limitations

• Column names and exact row counts are unknown across all sources.
• Metadata conflicts exist: last updated dates range from 1993 to 2026.
• File formats are diverse (PDF, ZIP, PNG, etc.), suggesting potential documentation rather than a single core data table.
