- The use of bicycles in Italy is still poor and the main cause of this phenomenon is certainly relating to a general lack of safety in cycling. In the last decade the trend of road accidents and victims is generally decreasing, but, at the same time, the number of cyclists involved in road accidents increased by 24,5%. The causes of this high accident rate is mainly relating to a lack of national legislation or to standards which are old, often overlapped to regional guidelines, uneven, confusing and in some case also contradictory.In terms of cycle network planning, it should be reminded that in Italy there is no regulation that establishes the criteria for a functional classification of bicycle paths. As a consequence, the infrastructure geometry and facilities (bicycle parking, places of refreshments, cycle repair shops, etc.) are not properly put in relation to the role played by the cycle path in the territory.In the course of time, we assisted to the realization of isolated cycle path trunks, generally out of a planning strategy and characterized by their own geometry. Therefore, taking also inspiration by the standards developed in other European countries, this research tries to provide guidelines for pre-normative functional classification of cycle paths, for their design and planning, in order to obtain safe and homogeneous cycling routes in Italy.It should be noted that the technical solutions, devices and traffic regulations, adopted in other countries, are very effective for a safe cycle mobility, but need to be revised in relation to the existing Italian law.

- A loss of natural capital within cities and their surrounding areas has been noticed over the last decades. Increasing development associated with higher sealing rates has caused a general loss of Urban Green Spaces (UGS) within the urban environment, whereas urban sprawl and the improvement of road networks have deeply fragmented the surrounding landscape and jeopardized ecosystems connectivity. UGS are an essential component of the urban system, and their loss has a greater impact on, e.g., ecological and hydrological processes, threatening human well-being. Different types and spatial configurations of UGS may affect their own ability to provide ecosystem services, such as biodiversity support and water regulation. Nevertheless, the study of UGS spatial patterns is a research branch poorly addressed. Moreover, UGS analyses are mainly focused on public and vast green spaces, but seldom on informal, private, and interstitial ones, returning a myopic representation of urban green areas. Therefore, this study investigates the UGS spatial patterns within six Southern European cities, using the urban morphology analysis to assess all urban vegetated lands. Results revealed three main Urban Green Spatial Patterns (UGSPs): Fragmented, Compact, and Linear Distributions. UGSPs taxonomy represents a novelty in the urban morphology field and may have important implications for the ability to provide ecosystem services and, thus, human well-being.

- The major event that hit Europe in summer 2021 reminds society that floods are recurrent and among the costliest and deadliest natural hazards. The long-term flood risk management (FRM) efforts preferring sole technical measures to prevent and mitigate floods have shown to be not sufficiently effective and sensitive to the environment. Nature-Based Solutions (NBS) mark a recent paradigm shift of FRM towards solutions that use nature-derived features, processes and management options to improve water retention and mitigate floods. Yet, the empirical evidence on the effects of NBS across various settings remains fragmented and their implementation faces a series of institutional barriers. In this paper, we adopt a community expert perspective drawing upon LAND4FLOOD Natural flood retention on private land network (https://www.land4flood.eu) in order to identify a set of barriers and their cascading and compound interactions relevant to individual NBS. The experts identified a comprehensive set of 17 barriers affecting the implementation of 12 groups of NBS in both urban and rural settings in five European regional environmental domains (i.e., Boreal, Atlantic, Continental, Alpine-Carpathian, and Mediterranean). Based on the results, we define avenues for further research, connecting hydrology and soil science, on the one hand, and land use planning, social geography and economics, on the other. Our suggestions ultimately call for a transdisciplinary turn in the research of NBS in FRM.
