“…Efforts to describe such linkages in the case of fishery resources have been criticized as overly simplistic (Penney, Wilson, & Rodwell, 2017). This growing criticism stems from the increased understanding that marine social-ecological systems (SESs) are complex adaptive systems (CAS), characterized by nonlinear dynamics and multiple possible outcomes (Hughes, Bellwood, Folke, Steneck, & Wilson, 2005;Morrison, 2017;Österblom et al, 2013), and that conflict over marine resources can itself be an outcome as well as a driver within those systems (Pomeroy, Parks, Mrakovcich, & LaMonica, 2016). In this review, we test the validity of the claim of simplicity (Penney et al, 2017) by assessing the degree to which the fisheries conflict literature, encompassing both subnational and international conflict, has incorporated ideas from complexity theory and SESs theory and identifying areas within this literature that would benefit from further development.…”
