criteria could be used to derive user-specified preferences (weights) for aggregation in the
real-time use of the model in public settings. However, for this paper, equal weights were
considered for all indicators.
A high OI indicates relatively higher adverse impacts on sustainability. This is because
all the indicators, except agricultural output, were designed to represent unsustainability.
For aggregating in the OI, the Agricultural output indicator value was taken as 1
(standardized score of Ag output). Fig. 9 shows the OI values for all scenarios. Maximum
adverse impacts on sustainability are observed for the Agbus-b scenario. Prot-a scenario
results in the least unsustainability followed by the Vege-a scenario. It should, however, be
noted that these summary results have been obtained by assigning equal weights to all of
the indicators. Different stakeholder groups may place different importance on various
issues, which will result in different values of the index.
