Abstract: Urban areas are growing, often at the expense of native ecosystems. As a result, indigenous lands (ILs) have become critical refuges for biodiversity, essential for sustainability and sit at the intersection of cultural, economic, and environmental interests. ILs play a double role in this context: they protect native biodiversity but are often framed as barriers to economic growth. In Brazil, nearly 14% of the territory is demarcated as ILs. This has led to conflicts with Brazil’s agricultural sector, particularly in the southernmost states, where agribusiness drives the economy. We hypothesize that this conflict leads to agricultural encroachment of ILs, which might become extension of farms, compromising their sustainability. We analyzed two decades of public data on soy coverage within ILs in Brazil’s southernmost states (Paraná, Santa Catarina, and Rio Grande do Sul) and found that soy cultivation in ILs increased by over 116% in the last two decades, peaking in 2019 at 177% above the 2001 baseline. We argue that ILs urgently need a framework that enables the communities therein to benefit from income originating from land lease, while ensuring that encroachment is limited and does not pose threats to native biodiversity. This can be challenging due to growing political pressure to weaken socioenvironmental protection and ILs’ demarcation but is nevertheless essential for the sustainable coexistence of urban areas, farms, and ILs.
