Environmental improvements and land-use reforms in disadvantaged neighbourhoods may actually trigger exclusion by driving property' prices up and attracting wealthier residents while displacing working-class residents (Cowell and Thomas, 2002; Banzhaf and McCormick, 2007; Bunce, 2009; Dale and Newman, 2009; Dooling, 2009; Quastel, 2009; Checker, 2011). This concern is reinforced in brow'nfield areas, where gentrification becomes extremely profitable through the realisation of the rent gap, the difference between actual and potential ground rent (Smith, 1979). Urban regeneration strategies therefore need to strike a careful balance between environmental and socio-economic goals. Designing urban spaces that are “just green enough” requires government authorities, residents and business ow'ners to w'ork together to achieve environmental remediation without environmental gentrification.
