A new report by the Joint Research Centre of the European Commission on “Scientific evidence showing the impacts of nature restoration actions on food productivity” has been published recently. This report is a narrative review of the effects reported in the scientific literature about the relationships between some nature restoration practices and food production. The reported effects are extracted from systematic reviews, meta-analyses and individual papers. 
Although we cannot extract a quantitative estimate without a proper meta-analysis, our review suggests that nature restoration measures have a remarkably positive impact on food productivity in the long-term, while most of the short-term impacts are context- and species-dependant. Thus, we consider that the restoration of degraded and overexploited ecosystems is an insurance policy to ensure the long-term sustainability and resilience of our food systems.
