摘要

Our study analyzes potential agro-industrial soybean expansion dynamics and is the first to project soybean expansion Paraguayan Chaco. This biodiverse region, home to the greatest diversity of indigenous groups in Paraguay, has recently seen some of the world's highest deforestation rates, losing 3.4 Mha of forestland between 2001 and 2014. Soy, a globally traded commodity crop and Paraguay's largest export product, recently arrived in the area and may exacerbate the high deforestation rates currently attributed to pastureland expansion. We combine extensive field, trade, and satellite data, to analyze the context, and push-pull factors that are driving frontier expansion dynamics, and assess the potential impacts of soybean-based land use change using geo-located accounts of current soybean production sites. Our analysis finds that roughly 742,000 ha in the Paraguayan Chaco are suitable for soybean frontier expansion with an additional 940,000 ha moderately suitable for expansion. We identify the main drivers of soybean expansion in the region as agricultural technology and land price appreciation. However, infrastructure investments are set to further drive soybean expansion dynamics and connect the region via navigable rivers and roads with access to ports on the Atlantic and Pacific oceans as part of the multi-national Corredor-Bioceanico "bi-oceanic corridor" road project. The continued rapid development of this fragile landscape could transform the Paraguayan Chaco into a major South American logistics hub for soybean and other agricultural production. Without appropriate governance systems in place, this development could lead to irreversible large-scale damage to the socio-environmental systems, similar to boom dynamics seen in other South American frontiers.
