Net present value (NPV) comparison for different yield and price scenarios across the four vineyards studied (Optimistic, minor yield declines and higher prices; Pessimistic, larger yield reductions and lower prices). Reported values are the differences in NPV between regenerative agriculture (RA) under each scenario and the conventional viticulture baseline calculated in Table 4. The RA scenario refers to the outsourced implementation. Bold text highlights the only scenario with a positive profit.
