“…Since coming into use in the late 1990s (Moore, 1996;Cooney, 2017), the concept of SLO has evolved, and is now much discussed in T academia, industry and management circles (Prno, 2013;Boutilier, 2014;Jijelava and Vanclay, 2014a;Moffat and Zhang, 2014;Morrison, 2014;Hall et al, 2015;Moffat et al, 2016;Smits et al, 2017). Although there are various competing models (Zhang et al, 2015(Zhang et al, , 2018Lacey et al, 2017;Wright and Bice, 2017), and notwithstanding that SLO is intended to be a metaphor (Prno and Slocombe, 2012;Bice, 2014;Bice and Moffat, 2014), the basic idea is that SLO is a continuum on which a number of levels can be identified, for example: withheld, when there is no support for the project; acceptance, when local communities are not actively opposed to a project; approval, when local communities view a project positively; and psychological identification, when local communities strongly support and welcome a project (Thomson and Boutilier, 2011;Jijelava and Vanclay, 2017). SLO is often described as being an implicit social contract between a project and its host communities (Bice, 2014;Lacey and Lamont, 2014;Demuijnck and Fasterling, 2016;Lacey et al, 2016).…”
