“…At higher scale levels, computer simulation models, performing a comprehensive analysis of the land-use system, appear to be indispensable research tools (Bouma et al, 2007). This was acknowledged by the European Commission, who introduced Impact Assessment Guidelines and promotes the use of modelling tools to make policy development better informed and improve the quality of European policies (EC, 2005;Bäcklund, 2009;Thiel, 2009). This resulted in a large number of studies on impact assessment of land use, policies and sustainable development (e.g., Boulanger and Bréchet, 2005;Rossing et al, 2007;Hacking and Guthrie, 2008;Walter and Stützel, 2009;Binder et al, 2010).…”
