Impact of digital development on farm performance and agglomeration dynamics

All firm attempt to improve their economic performance, however in our modern-day world, they must be also concerned about their environmental performance. New digital technologies are seen as a new source of performance and innovation gain. In this thesis we will investigate how far these technologies can improve the farm's economic and environmental performance. Also, we will investigate how far these technologies influence the agglomeration and the concentration of agricultural activities by realising the constraints of geographical proximity for the accumulation of knowledge (spillover of knowledge localized) and/or by reducing the congestion tfacors related in particular to regulations and to the environmental nuisances.
