a, The control variables for each of the Earth system processes used for the elicitation purposes. Control variables indicated with an asterisk are the same as defined in ref. 7. For control variables without existing boundary values, safe ranges were developed and set (Supplementary Section 2). b, A hypothetical area of 100 km2 with control variables within safe ranges was used to assess the interactions among the Earth system processes relevant to food production by experts in this scenario-based elicitation.
