Our cities are often characterised by a complex, ungrammatical articulation of spaces, volumes, intended uses, and values. The residual green urban areas are representative of a low level or absence of order, but above all, of functions and values. The study proposes a new methodological and operational approach to the rehabilitation of green residual urban areas, participatory type that can generate a new order between values, functions and actors, to mediate private and public needs, to promote new forms of responsibility and thus to implement some of the priority objectives set out in the 2030 Agenda. The operational tools supporting the approach are the Contingent Valuation Method (CVM), public and private partnership (PPP) and crowdfunding. This approach supported the selection of the project and the creation of a budget with public and private funding to support the participatory rehabilitation of a residual green urban area in the municipality of Acireale. The amount of funding identified largely covers rehabilitation costs. The issue of the quality and quantity of urban greenery is crucial for the sustainability and resilience of cities to climate change. Rehabilitation of remaining urban green areas is an opportunity to meet the new needs of green areas, supporting communities in this new challenge.

剩余绿色城市地区的价值论

我们的城市通常以空间、体量、预期用途和价值的复杂、不合语法的表达为特征。剩余的绿色城市区域代表了低水平或无秩序，但最重要的是功能和价值。该研究提出了一种新的方法论和操作方法来恢复绿色剩余城市地区，参与型可以在价值、功能和行为者之间产生新秩序，调解私人和公共需求，促进新形式的责任，从而实施2030 年议程中提出的一些优先目标。支持该方法的运营工具是或有估值法 (CVM)、公共和私人合作伙伴关系 (PPP) 和众筹。这种方法支持了项目的选择，并通过公共和私人资金制定了预算，以支持阿奇雷亚莱市剩余绿色城区的参与式修复。确定的资金数额主要包括康复费用。城市绿化的质量和数量问题对于城市对气候变化的可持续性和适应力至关重要。剩余城市绿地的修复是满足绿地新需求的机会，支持社区应对这一新挑战。城市绿化的质量和数量问题对于城市对气候变化的可持续性和适应力至关重要。剩余城市绿地的修复是满足绿地新需求的机会，支持社区应对这一新挑战。城市绿化的质量和数量问题对于城市对气候变化的可持续性和适应力至关重要。修复剩余的城市绿地是满足绿地新需求的机会，支持社区应对这一新挑战。
