“…However, as I have suggested earlier (Visseren-Hamakers, 2015), “the debate on fragmentation has itself been rather fragmented,” with authors from different disciplines contributing to the debate over time, using different terminologies, focusing on different levels of governance, and studying relationships between various units of analysis. Used concepts include interorganizational relations (see e.g., Schmidt and Kochan, 1977), legal pluralism (Griffiths, 1986; Merry, 1988), polycentric governance (Ostrom, 2010), regime complexity and fragmentation (Alter and Meunier, 2009; Biermann et al., 2009; Fischer-Lescano and Teubner, 2003), integrated management (Born and Sonzogni, 1995; Hughes and Pincetl, 2014), landscape governance and approaches (Buizer et al., 2015; Görg, 2007; Sayer et al., 2013), (environmental) policy integration (EPI) (Jordan and Lenschow, 2010; Persson et al., 2018; Weber and Driessen, 2010; Winkel and Sotirov, 2015), coordination (Geddes and Jordan, 2012; Peters, 1998), mainstreaming (Brouwer et al., 2013; Karlsson-Vinkhuyzen et al., 2017; Kok and de Coninck, 2007), coherence (Jones, 2002), smart regulation and policy mixes (Gunningham and Grabosky, 1998), multilevel governance (Hooghe and Marks, 2003; Marks et al., 1996; Rambonilaza et al., 2015), governance architectures and systems (Biermann et al., 2009; Visseren-Hamakers, 2009), regime complexes (Abbott, 2012; Raustiala and Victor, 2004), institutional interaction and interaction management (Oberthür, 2016; Oberthür and Gehring, 2006), metagovernance and orchestration (Abbott Kenneth and Bernstein, 2015; Abbott and Snidal, 2010; Kooiman and Jentoft, 2009), telecoupling (Liu et al., 2013), the governance of complex systems (Young, 2017), and the nexus approach (Benson et al., 2015; Rasul and Sharma, 2016).…”
