Furthermore, globally 19.2% of the land that would climax to grassland (primary) is estimated to have been converted for arable production, despite the general perception that the environment therein is often too arid, too cold or otherwise unsuitable for intensive farming systems19. Consequently, ...
However, the combined impact of the agricultural input shocks on crop yields has not yet been systematically assessed globally. Here we modelled the effects of agricultural input shocks using a random forest machine learning algorithm. We show that shocks in fertilizers cause the most drastic yield ...
