El Niño-fueled megafloods at Iguazu Falls expose South America’s climate vulnerability and Indigenous warnings ignored for decades

The Guaraní and other Indigenous groups have long documented the Paraná River’s erratic flows, attributing them to deforestation and the disruption of *tekoha* (sacred territories). Their traditional *mborevy* (floodplain) management—including controlled burns and wetland preservation—could reduce flood risks by 30–40%, but these practices are criminalized under agribusiness-dominated land laws. The 2007 *Convenio 169* (ILO Indigenous Rights Convention), ratified by Argentina and Brazil, mandates their inclusion in climate adaptation planning, yet local governments ignore these obligations. The current surge mirrors the 2003 floods in Misiones Province, when Guaraní leaders predicted ecological collapse but were dismissed as ‘alarmists.’
The Iguazu Falls’ record flow is not an isolated ‘natural’ event but the culmination of centuries of colonial extraction, neoliberal environmental neglect, and the systematic erasure of Indigenous ecological knowledge.
The Guarani’s warnings about deforestation and dam construction—dismissed as ‘superstitious’—align with scientific projections of hyper-floods, yet their solutions are excluded from policy. The trickster here is the myth of ‘untouched nature,’ which obscures how agribusiness lobbies and complacent governments have turned the Paraná Basin into a flood-prone disaster zone. To break this cycle, power must shift from technocratic control to Indigenous-led governance, where rivers are not resources to be exploited but relatives to be respected. The path forward lies in restoring *tekoha*, decommissioning ecologically destructive dams, and funding marginalized communities as first responders to climate chaos—not as victims, but as stewards.
