Fig. 3. Analysis of workshop data and the results of other regional studies highlighted key drivers and focal relationships influencing land use in Iowa’s agricultural landscapes (Table 2). Exogenous system drivers are macroscale influences on the system that set the range of possible futures. Endogenous drivers are regionally controlled system components that vary across potential futures to influence the patterns and processes of future landscapes. Exogenous and endogenous drivers combine to influence multiple ecosystem services and societal goods, all of which were seen as important outcomes of rural landscapes.
