Abstract
The unresolved territories are privileged places for the proliferation of degradation phenomena that affect the environment and human well-being. The impacts of their critical conditions go beyond the limits of the damaged urban fragments, involving the built environment, society, economy, culture, and conditioning quality of life. This paper proposes a methodological approach to landscape design supported by an evaluation framework to orient strategic design planning with specific attention to unresolved territories consistent with the circular economy perspective. The circular city principles are applied to landscape spatial planning, by operationalising Ecosystem Services, Landscape Services, and Ecosystem Disservices, as interpretative categories for multi-dimensional regenerative strategies. Starting from a theoretical framework, the objective of the analysis is to implement an approach to the regenerative design of landscapes of waste, defined wastescapes. The industrial area of East Naples is the case study where an incremental evaluative approach has been defined to design scenarios to provide services and values, aimed to drive the conversion in a regenerativescape. A multi-criteria analysis through preference ranking organisation method for enriched evaluation (PROMETHEE)-GAIA method has been implemented to compare the base case scenario with two incremental new scenarios and identify situated sustainable priorities.
Highlights
Two-thirds of the European Union (EU) population resides in urban areas, and they use around 80% of energy resources [1], determining critical conditions for quality of life and increasing crisis complex environments
The implementation and optimisation of some composite indicators aim at driving the transition of wastescapes in regenerativescapes, in a progressive and systemic logic to host adaptive processes developed in incremental phases
Pairwise comparisons of alternatives are based on three preference flows to consolidate the results: Positive, negative, or net flow
Summary
Two-thirds of the European Union (EU) population resides in urban areas, and they use around 80% of energy resources [1], determining critical conditions for quality of life and increasing crisis complex environments. The widespread crisis in urban areas in recent decades has led to the definition of European plans and agendas to adopt common policies [2] and to activate shared processes to support cities policies, where human settlements act as main catalysts for creativity and innovation across the EU. Anyhow, they are places where various persistent environmental problems reach the most worrying levels, especially related to waste proliferation. The New Urban Agenda, adopted at the United Nations Conference on Housing and Sustainable Urban Development (Habitat III), aids as a shared vision for world urban areas for the 20 years [5]
