Does improved tenure security reduce fires? Evidence from the Greece land registry

While tenure security is essential to effective land management, there is little empirical evidence on its environmental impact. Exploiting the staggered rollout of the land registry program across Greece, we find the regions covered by the mandatory program witness large declines in agricultural fire events, burned areas, and air pollutants. Agricultural data reveal that landowners in those regions mitigate fire risks through reducing stubble burning, expanding farming areas, and stocking more fire-suppression equipment. Our findings indicate that strengthening property rights can lead to more sustainable farming practices and promote long-term land investment, thereby reducing fire hazards.
