Universities are central players and important economic actors in many regions, and many of them are, in general, nationally and internationally active in respect of matters related to sustainable development. But there is a paucity of research which examines their contributions towards sustainability efforts at the local level, i.e. in the places they are situated. This paper addresses this need, by reporting on a qualitative study deploying a Matrix, which allows an analysis and reporting of regional sustainable development initiatives of a set of 22 universities in industrialised and developing countries. Recommendations to enhance their role are provided, including the importance of pursuing partnerships and joint initiatives, understanding the need of local communities, and making their know-how more widely available. The scientific value of this research is related to the understanding of how the interaction between universities and local communities happens and by shedding light to this topic, it supports universities to improve their own actions. Its implications are twofold: it demonstrates the potential of universities as local players, and outlines the range of activities they may engage with, and which may allow them to act as pillars to local sustainability initiatives.

Walking is a sustainable mode of transport and a healthy way of doing physical activity. Walkability is a concept that has gained enormous popularity in recent years due to its potential to promote more sustainable urban environments and healthy lifestyles. This paper provides a literature review to analyze the influence of built environment attributes on walkability. The Scopus and Web of Science databases were chosen to survey the peer-reviewed documents published up to June 2020. A total of 132 documents were selected by the search. The review of these 132 documents showed that various built environment attributes were differently analyzed and assessed. More specifically, the search identified 32 built environment attributes that were assessed by using 63 measures. Intersection density, residential density and land use mix were the most used attributes for assessing walkability, namely by using objective methods, such as ratios and spatial score tools. In turn, attributes related to streetscape design and security were much less adopted in walkability assessments. This paper provides additional insights into how built environment attributes influence walkability and identifies gaps and issues that should be analyzed in-depth in the future. The review could be helpful for researchers and urban planners in developing walkability studies and in defining policies to improve walkability.

The definition and the subsequent development of eco-industrial parks (EIPs) have been deeply based on the application of industrial ecology theory, which pays specific attention to metabolic exchanges within industrial processes to address a deep reduction of limited resource consumption and a minimization of waste production in the framework of a sustainable development approach. Despite the EIPs configurations being essentially based on the overall idea of sustainability, the problem of defining their proper location inside the territory and the consequent land use model, to minimize land consumption, have not always been central in the wide range of studies and practices concerning the EIPs. Nevertheless, the specific problem of a drastic reduction of land consumption at the EIP planning stage acquires a crucial role and, therefore, needs to be carefully assessed inside the perspective of sustainable urban development. In this framework, the paper firstly aims at facing the nontrivial relationship between the EIPs' theorizations and implementations and the reduction of land consumption by referencing specific studies and shared tools, where new developments have been favored despite the conversion and redevelopment of existing industrial parks; secondly, it focus on an Italian case study and its emblematic EIP planning processes, in order to deepen the contradictions between sustainable spatial planning and eco-industrial parks. Finally, some final conclusions will be presented, in order to integrate some main issues concerning the reduction of land consumption inside the more traditional EIP design processes.

Walking is a mode of transport that offers many environmental and health benefits. Utilitarian walking refers to walking trips undertaken to fulfil routine purposes. The aim of this paper is to examine the extent to which walking is used as a transport mode for short urban trips in the city centers of Bologna and Porto and the barriers preventing utilitarian walking. Based on a questionnaire (n = 1117) administered in the two cities, results indicated that 21% of the individuals travel by foot, while 47% combine walking with other modes. This means that 68% of the daily trips to these city centers involve walking activity. From the overall trips, 84% were made to reach work and school/university. Statistical tests showed that utilitarian walkers were more likely to be females (p < 0.001) and undergraduates (p < 0.001). People from Bologna were more likely to engage in utilitarian walking than people from Porto (p < 0.001). Travel distance and time were the main barriers preventing people from engaging in utilitarian walking. The findings described in this paper provide a better understanding of utilitarian walking in the central areas of both cities, which can guide policies to promote healthier lifestyles and sustainable mobility.

Rural areas in Europe host more than 55% of the overall population and embed a unique and peculiar cultural and natural heritage. Nevertheless, they are facing common issues of disengagement, depopulation and economic and social crises. Rural communities are increasingly interested in setting up inclusive and participatory regeneration processes, but participatory planning experiences in rural areas are still limited. This paper introduces the Community-based Heritage Management and Planning methodology (CHMP) developed within the RURITAGE project, and analyzes and presents the results of its implementation in six demonstrators around Europe and beyond. The methodology is based on the establishment of Rural Heritage Hubs (RHH), intended as the community of local stakeholders and a physical place to run the co-creation activities. We used four types of feedback—online survey, in-presence survey, consultations and interviews with RHH Coordinators—to analyze the implementation of the CHMP. The research findings show that through built capital (RHH places activated) and through the activation of local social and human capitals (RHH communities engaged in the process), participatory processes can attract local communities and engage them into the development and the implementation of local regeneration plans, fostering heritage ownership and inclusion.

Densification is generally proposed as the solution to the excessive soil consumption that has characterized the urban development of European cities in the recent decades. Even if the "compact city" can generally be regarded as a preferred urban form over the "dispersed city", the strategy of densification is not applicable to any context, leaving aside the local conditions. Densification operations should consider the state of the environmental and urban context and assess threats and opportunities offered by the specific site. Thus, this paper describes a method for the environmental sustainability analysis of the built urban fabric. It proposes a set of sustainability objectives and pre-conditions to be evaluated in order to estimate the possibility to increase the urban density without compromising the environment, and it defines implementation measures, declined for the various environmental aspects which are considered to be affected by the densification interventions (water, soil, energy, electromagnetism, seismic, public facilities, waste, mobility, noise, air). The implementation measures are considered as guidelines for the inclusion of new volumes or for the completion of existing ones into the built areas, to be codified in the municipal building rules in order to guarantee the sustainability of the densification. The theme is explored both at the building scale and the urban scale, considering both the environmental aspects dealing with the building, such as the energy and seismic improvement, the urban morphology and the infrastructures capacity at urban scale, such as transport and green networks, water and road traffic flows.
