“…In the discipline of system dynamics, the system boundaries are determined relative to behavior(s) of interest, and a system is defined as the structural components and causal connections that lead to the behavior(s). Very frequently, coupled systems are defined by geographical, political, administrative, and management boundaries, e.g., continental, national, subnational, regional, provincial, state, county, township, village, nature reserve, protected area (Asbjornsen et al 2015, Dong and Sherman 2015, Rammer and Seidl 2015, Boone and Lesorogol 2016, Giuliani et al 2016, Iwamura et al 2016, Noel and Cai 2017, Shindler et al 2017, Tesfatsion et al 2017, which may include both social and natural boundaries, e.g., in the example of Wolong Nature Reserve as an administrative unit. Such a definition has some advantages.…”
