Resumen de The role of regulation in the land-take control. The italian case of the metropolitan city of cagliari
Anna Maria Colavitti, Sergio Serra
Using natural land for the transformation of settlements into extensive and sprinkled agglomerations is particularly clearly seen in the urban and the metropolitan contexts. The European Union provisions will move the European Countries towards the target of zero land-take by 2050, including regulatory measures and incentives to pursue this goal. This paper proposes to assess the effectiveness of the regulatory approach adopted by Italy for landscape planning. In particular, the Landscape Plan developed by Sardinia Region will be analysed. This one aims at limiting the urban expansion for the construction of new housing units only as a result of actual housing requirements that cannot be met only through the recovery and reuse of areas. Focusing on the case of Cagliari metropolitan city, the study assesses the increase in the urbanised areas as well as the incoherence among the demographic trends – the housing needs and the planning of new residential expansion in the municipal urban plans adapted to the Regional Landscape Plan. The research highlights the ineffectiveness of landscape planning regulation in the reduction of land-take phenomenon and the need for a strategy at the supra-municipal scale to coordinate urban demand planning.
