Abstract
Mechanization is a key ingredient for raising agricultural productivity. Currently, however, globally comparable information on agricultural mechanization rates is hard to come by. Here, we globally model agricultural mechanization at an unprecedented ~ 5km resolution and examine its empirical association with crop yield gaps but also soil compaction and forest loss. We find that many high-income countries are close to fully mechanized by now, whereas, especially in Sub-Saharan Africa and Southern Asia, mechanization rates are still low. We then estimate that for each ten-percentage point increase in the mechanization rate, the average crop yield gap shrinks by 2 to 3 percentage points and soil compaction increases by 1.5 to 2 percentage points. There is no clear effect of agricultural mechanization on tree cover loss.
