Trade-offs between agriculture and biodiversity conservation in the South American Chaco

Rapid agricultural expansion and intensification threatens the Chaco’s unique biodiversity, but the exact relationship between the loss of natural areas and biodiversity patterns remains weakly understood. Within the DFG-funded CHACO project we map land-use changes during the past 30 years and improve understanding of consequences for biodiversity in the Chaco, with the goal to identify trade-offs between the contrasting goals of agriculture and conservations.
