Sources: 5. Developments: 2. In Curitiba, Brazil, local authorities and social movements are navigating the intersection of urban development, housing rights, and environmental protection. Officials and activists have held workshops to implement Municipal Decree 390/2026, which sets new parameters for regularizing occupations in flood risk areas and permanent preservation zones. This effort seeks to balance the necessity of dignified housing in communities like Bom Menino and Nossa Senhora da Paz Norte with legal environmental requirements. Concurrently, the ‘Despejo Zero no Paraná’ campaign, representing over 9,000 families, has formally presented demands for land and housing rights to political candidates. In a separate effort to bolster environmental preservation, the Curitiba city council is considering a land exchange project to expand São Lourenço Park. The proposal involves trading a plot in Vista Alegre for ten lots in Colônia Abranches containing native forests. This exchange is intended to support the Rio Belém Hydrographic Basin Revitalization Plan by increasing leisure areas and reducing siltation in the park’s lake. ## Timeline ### 2026-09-11: Curitiba considers land exchange to expand São Lourenço Park Curitiba officials are voting on a land exchange with Urbs to expand the São Lourenço Park preservation area and support the Rio Belém revitalization plan. 3 sources. https://clstr.news/cluster/curitiba-considers-land-exchange-to-expand-so-loureno-park ### 2026-08-31: Curitiba officials and activists debate land rights and environmental preservation Stakeholders in Curitiba are navigating land regularization in environmental zones while social movements demand stronger housing rights and land protections from political candidates. 2 sources. https://clstr.news/cluster/curitiba-officials-and-activists-debate-land-rights-and-environmental-preservation --- Cite as: Curitiba land rights and environmental preservation.
