This paper addresses quarries rehabilitation issue within a Metropolitan Area. Areas where mining activity is carried out have been subjected to physical and environmental degradation linked both to pursue the building materials extraction and to the city expansion continuously asking for new areas to be developed with residential and service functions. These changes also occurred where environmental and landscape values are present. It has been therefore pointed out the issue of such areas redevelopment that, to be functionally reintegrated, must be consistently linked to the activities and the territorial local contexts characteristics. In this paper the quarries reuse issue is carried out through parameters identification able to define the quarries relationship with the neighboring towns and with their surroundings besides to identify their physical, environmental and landscaping characteristics. Quarry reuse alternatives have been identified among those consistent with the rehabilitation goals, as defined by the planning sector and internationally approved, while their selection is derived from the application of a two-step methodology: a multi-criteria analysis related to punctual parameters at a "site-specific" level, followed by a further territorial indicators checking over the wide area. This application has led to socially accepted results identifying the examined quarries for reuses ranging from agricultural-forestry and urban to functional or naturalistic. The proposed method has also proved to be suitable to address the abandoned quarries reuse problem with a systemic and consultative approach, as it is able to correlate the many variables present in the social and spatial complexity of the Metropolitan Areas.
The study analyses the greenway projects implemented in Italy, summarising their characteristics in a table that contains basic information concerning the geographical location, year of implementation, the type of layout and size, the state of implementation; the Institution that proposed the implementation, the official name, the territorial feature, the socio-economic and cultural aims, references to bibliographic and web resources and to their inclusion in plans and projects. The analysis has allowed to verify the compliance of individual contributions to the definitions attributed to the greenway from national and international associations. It has been possible to verify the use of greenways as physical support to spatial planning and the promotion of economic and productive development of rural areas
Agroforestry areas have a significant and recognized productive, socio -economic, environmental and landscape role. An important ecological function performed by these areas is the net absorption of considerable quantities of atmospheric carbon dioxide. The scientific knowledge of the CO2 assimilation capacity of agroforestry ecosystems in a territory, is a useful and innovative means to support territorial planning. In the interests of environmental sustainability, emissions from human activities carried out in a specific local context, must be adapted by the simultaneous capacity of CO2 sequestration. For the protection of environmental quality, the choice of land use should therefore optimize the circuit of interaction between emissions and absorption. This work takes into account the agroforestry areas of the Province of Bari to estimate the potential capacity to absorb CO2 and compare it, with the current emission levels.
