摘要

The paper studies the dynamics of agricultural land use at the global scale as measured from space using satellite imagery between 2003 and 2018. It shows large global movements in and out of cropland and correlates these movements with biophysical, economic, and institutional variables. The empirical identification of these effects relies on a two-stage approach that disentangles the effect of local geography from national-level characteristics. Beyond the anticipated influence of local geographic factors (such as droughts leading to land degradation) or market access (such as proximity to cities facilitating cropland expansion), this study makes a substantial contribution by demonstrating the significance of national economic contexts and institutions. In particular, the research finds that income inequality, weak land administrations, land tenure insecurity, a bad business environment, and pressure on land resources are closely associated with cropland loss and land degradation.
