Analysis of only smallholder studies by region and development class. Pollination and biological control studies from smallholder farming landscapes as a percent of all unique pooled studies for each service are compared by A) World Bank regions and B) development class. Expected values for A and B were derived from [9, 17] and were generated by multiplying the global percent of agricultural land/agricultural population for a region/development class by the within factor percent that was estimated to be smallholder.
