This report from international consultancy SYSTEMIQ sets out how farmers in different regions across Europe can transition profitably to regenerative agricultural practices. It estimates that soil degradation currently costs the European Union €97 billion per year, mostly in damage to human health.
The report lists regenerative farming practices, including minimising the use of agrochemicals, avoiding bare soil (e.g. cover crops), minimising soil disturbance, and maximising on-farm biodiversity. It also uses arable farming in France and orange growing in Spain to illustrate the costs involved in transitioning to regenerative practices.
