Soil pollution diffusion in a spatial agricultural economy
Résumé
There exists a pressing need to analyze the impact of agriculture on soil fertility. This paper develops a spatial growth model for an agricultural economy, in which pollution diffuses across space. In order to produce, the economy needs fertile soil, naturally bounded by the amount of available land. When regions have not yet reached their maximal soil fertility, they can locally invest in abatement in order to reduce soil pollution. Once a
location reaches this maximum of fertile land, the economy is split in two: a fertile region and a polluted region. We analytically show how the polluted region can either stagnate at low levels of fertility, or catch up with the fertile region. Our results are numerically illustrated, including the resiliency of the economy to recover from pollution shocks.
