Political Backing Fuels Land Grabbing in Brazil's Distrito Federal

In the Distrito Federal, Brazil, a significant issue of land grabbing in conservation areas is emerging, intensified by political support. These activities are particularly rampant in the Colônia Agrícola 26 de Setembro, a settlement approximately 26 km from the Palácio do Planalto, housing around 35,000 residents. This area, characterized by its lack of urban infrastructure and public services, was largely built on public lands designated for conservation.
