“…The first line of research focuses on identifying the determinants, often termed as ‘enablers and barriers’. The research on the barriers on donor’s side, for instance, identified various factors such as sectoral departmentalization or specialization (Hertin and Berkhout, 2001; Peters, 1998), absence of policy assessment processes (Nilsson and Persson, 2003), lack of political commitment and low levels of awareness (Dessai et al, 2009; Lorenzoni et al, 2007). Though such studies have largely succeeded in identifying and categorizing these factors, they have been less successful in explaining the hidden dynamics of policy integration (Russel et al, 2018), like why certain barriers hinder mainstreaming (Eisenack et al, 2014) and what mechanism leads to effective mainstreaming (Biesbroek et al, 2015).…”
