Evidence

Preprint

Geography

Brasília integrated development region, Brazil

System

Watershed landscape indicators; urban growth

## WHAT THE EVIDENCE SAYS

A SciELO preprint maps land-cover-related vulnerability across parts of Paraná, São Francisco and Tocantins–Araguaia basins in the Brasília region over a multi-decade period. Indicators varied by basin and by the ecological dimension measured.

## WHY IT MATTERS / OUR READ

A single sustainability score can conceal divergent pressure on biodiversity, contamination pathways and land conversion; watershed planning needs separate indicators.

## CAVEATS / UNCERTAINTY

Preprint, not established peer review. Modeled vulnerability proxies do not directly measure water contaminants or ecosystem response; verify updates before using for decisions.
