“…There have been a number of studies and examination of sustainable development practice and its measurements at the local (Button & Pearce, 1989;Despotakis, Ciaoutzi, & Nijkamp, 1991;Saha & Paterson, 2008), regional (Berger, 2003;Healey & Shaw, 1993;Nijkamp & Ouwersloot, 1997;Roberts, 2006;Shearlock, James, & Phillips, 2000), national (Bass & Dalal-Clayton, 2007;Button & Pearce, 1989; Carew-Reid, Prescott-Allen, Bass, & Dalal-Clayton, 2013;Swanson et al, 2004), and international levels (Bebbington, 2001;Khan, 1995;Stren, White, & Whitney, 1992). However, there is almost no literature that addresses sustainable development at the megaregion level, while there is increasingly more recognition about the importance of megaregions as an emerging geographical scale that subsumes a great portion of population growth, economic growth, and environmental impact (Ross & Woo, 2011;Ross, Stiftel, Woo, & Rao, 2010;Wheeler, 2009).…”
