Abstract.The interplay between land take and climate change is reviving the debate on the environmental impacts of urbanization. Monitoring and evaluation of land-cover and land-use changes have secured political commitment worldwide, and in the European Union in particular -following the agreement on a "no net land take by 2050" target. This paper addresses the ensuing challenges by investigating how open data services and spatial indicators may help manage urban sprawl more effectively. Experts, scholars, students and local government officials were engaged in a living lab exercise centered around the uptake of geospatial data in planning, policy making and design processes. Main findings point to a great potential, and pressing need, for open spatial data services in mainstreaming sustainable land use practices. However, urban sprawl's elusiveness calls for interactive approaches, since the actual usability of proposed tools needs to be carefully investigated and planned for.
Strategic Environmental Assessment (SEA) is a major policy evaluation tool, for institutional processes, when they need to cope with fundamental risks, give voice to non-human agents, manage commons, and address environmental justice. The interplay of SEA with planning, unravels key issues and criticalities in both urban governance and environmental democracy. How can evaluation be developed to support the process? Structured evaluation methods applied in environmental assessment are maybe not sufficient to solve complex social conflicts. We point out some key reflections with the aim of opening up the discussion, by taking the case study of the environmental assessment of pollutant activities in the main industrial port cities of Southern Italy. They represent, at the moment, the most significant social criticality in our country, related to the interplay between environmental assessment and risk for labor. The paper focuses on the case study by mentioning the evolution of some thoughts about the red stripe that links sustainability, environmental democracy, and social evaluation, and illustrates the issues of these aspects in the case study, with the aim of underlining the difficulty of environmental assessment tools as a major support for planning processes, when social conflicts arise.
The purpose of this paper is to define a methodological proposal towards a Spatial Decision Support System for strategic planning, based on the evaluation of Cultural Landscape Services (CLS). A combination of multidimensional evaluation techniques, multi-group analysis and Geographic Information Systems is applied to the simulation of landscape enhancement scenarios in the "National Park of Cilento, Vallo di Diano and Alburni", in order to explore the effectiveness and helpfulness of the evaluation of CLS in structuring both hierarchic and networking relationships among the municipalities comprised in the study area
