“…Seventy-one articles were categorised by the year of publication and the type of participation mechanisms based on citizen participation models (Thomas, 2013;Roberts, 2004;Callahan, 2007;Nabatchi et al, 2017). One group of articles (52 articles of 71) deals with 'basic citizen participation mechanisms' involving simple one-or twoway citizen participation methods, such as public meetings, focus groups, simulations and advisory committees (Dudley et al, 2018;Ammons and Madej, 2018;Amirkhanyan et al, 2019;Kroll et al, 2019;van Holm, 2019;Jo, 2021), and political participation, such as mobilisations and protests (Marx and Nguyen, 2018;Schmidthuber et al, 2019;Nesti and Graziano, 2020). Citizens in this category might be considered informed observers or limitedly engaged participants in policymaking processes (Hensengerth and Lu, 2019).…”
