Joris Van Zeghbroeck, Michele Remer, Nicholas Manning, Emilio F. Moran, Jianguo Liu
TL;DR
The paper shows how economic and social factors at different scales influence agricultural land use in India and Argentina.
Contribution
The study introduces a metacoupling framework to analyze how socioeconomic flows affect cropland changes across local to global scales.
Findings
Intracoupled crop flows in India and Argentina significantly influenced cropland area changes.
Capital investments and migration flows impacted infrastructure and urban land expansion.
Domestic and international capital investments supported agricultural production infrastructure.
Abstract
Agriculture is the key to global food security and environmental sustainability; however, little is known about how cross-scale socioeconomic flows influence agricultural land use. We addressed this knowledge gap by evaluating the metacoupled flows of crops, capital investments, and migration. We assessed how these flows impacted land used for crop production in India and Argentina, which contain global biodiversity hotspots and high levels of agriculture. During our study time frame (1990–2015), land used for crop flows increased by 33.6 Mha, primarily driven by increases in crops produced for domestic consumption. Capital investments from distant countries and within the focal countries increased transportation infrastructure and processing capacity, supporting the expansion of crop production. Migration from adjacent countries and within the focal countries increased urban…
