This research aims to assess the effects of legal amendments and land use changes on riparian areas in São Paulo, Brazil.
Analyzed land use and land cover dynamics in riparian Permanent Preservation Areas (PPA) from 1985 to 2022.
Utilized geoprocessing and spatial statistics to identify patterns of native vegetation maintenance and degradation.
Compared historical conditions under different versions of the Forest Code.
Native vegetation transitioned from 54% being agricultural and forestry in 1985 to 49% being forest and natural formations in 2022.
Significant regeneration of native vegetation from pastures accounted for 262,297 hectares.
Anthropic areas increased by 113%, particularly in São Paulo's metropolitan region, with 0.4% of PPA already occupied by 1985.
