This study aims to analyze the atmospheric conditions associated with an event of intense precipitation caused by Easterly Wave Disturbances (EWDs), as well as the environmental conditions related to the mass gravitational movement that occurred between 14th June and 15th June of 2014, in the district of Mãe Luiza, Natal/RN/Brazil. The synoptic conditions, the vertical integrated moisture flux and the energetic behavior in the EWD’s performance phases were analyzed. In addition to these factors, local environmental aspects were assessed, classifying the vulnerability to disaster events in the affected area. Over the days of the operation of the atmospheric system, the daily accumulation of precipitation was greater than 100 mm, with precipitation accumulated in 3 h in the order of 60 mm for the stages of maturation of the disturbance. The main synoptic conditions associated with EWDs were exhibited by the intense anomalies of wind speed and high humidity flux on the east coast of the Northeast, which intensified the influx of moisture into the continent over the period of the operation of the system. Conditions of high to very high vulnerability were identified in the area where the event took place and also in other expressive parts of the district.

One of the priority lines of action in Poland is to increase energy production from renewable energy sources (RESs). Based on the “Poland’s national energy and climate plan for the years 2021–2030”, Poland aims to achieve 21%–23% of RES share in gross final energy consumption by 2030. While coal is still the most important source of energy, new technological and organisational solutions for increasing RESs are being tested and implemented. Therefore, the creation of energy clusters based on the idea of urban and industrial symbiosis was first proposed by the Ministry of Energy in 2016. To date, there are 66 clusters in different regions in Poland, but only a few of them are active and innovative. One of them is located in the city of Zakopane, a mountain resort, which attracts about 3 million tourists annually and has developed the wide-ranging use of geothermal sources for energy supply and recreation. The paper aims to analyse the impact of the creation of energy clusters on the city’s development, including economic, social, and environmental aspects. The “willingness to pay” (WTP) method was used to calculate the impact of air pollution on Zakopane and to compare it with the Polish average to estimate the significance of the transformation to RESs in this tourist city. The results from the studies are as follows: health cost per capita in Zakopane is between 252.07 and 921.30 euro. The investigations presented can be the basis for recommendations in strategic documents in the field of regional development and environmental protection, especially on the use and promotion of urban symbiosis for increasing use of RESs.

Urban regeneration involves the integrated redevelopment of urban deprived areas, covering physical, socio-economic and environmental aspects of cities, and it is concerned with interventions on early/inner-ring suburbs and historic centers, which are under pressure from population growth and sustainable development policies. The planning and management of urban regeneration interventions usually depend on the city and regional context. Although these interventions involve multiple issues and stakeholders, common characteristics can be identified, thus appealing for a holistic vision and coordination among the various dimensions of the problem. Based on the above context, and on the experience from a large-scale urban regeneration project, this article introduces an integrated methodology to support the planning and management of urban regeneration interventions. The methodology proposes a flexible baseline that can be adapted to urban regeneration projects of different contexts and dimensions, and defines steps, the corresponding stakeholders, and the teams’ engagement, in an integrated framework to plan and oversee urban regeneration actions towards more sustainable and resilient interventions.

New strategies to improve the quality of urban pedestrian environments are becoming increasingly important in sustainable city planning. This trend has been driven by the advantages that active mobility provides in terms of health, social, and environmental aspects. Our work explores the idea of walkability. This concept refers to the friendliness of the urban environment to pedestrian traffic. We propose a framework based on the multi-criteria decision analysis (MCDA) methodology to rank streets in terms of walkability levels. The city of Lisbon (Portugal) is the location of the streets under examination. Findings confirmed the framework’s replicability and suggested the possibility of this strategy being used as a support tool for designing urban policies.

As destination of choice for many short-term study abroad programs, Berlin offers students of German language, culture and history a number of sites richly layered with significance. The complexities of these sites and the competing narratives that surround them are difficult for students to grasp in a condensed period of time. Using approaches from the spatial humanities, this article offers a case study for enhancing student learning through the creation of digital maps and itineraries in a campus-based course for subsequent use during a three-week program in Berlin. In particular, the concept of deep mapping is discussed as a means of augmenting understanding of the city and its history from a narrative across time to a narrative across the physical space of the city. As itineraries, these course-based projects were replicated on site. In moving from the digital environment to the urban landscape, this article concludes by noting meanings uncovered and narratives formed as we moved through the physical space of the city.

Abstract Amendment to the Act on special rules of preparation and implementation of investment in public roads resulted in an accelerated mode of acquisition of land for the development of roads. The decision to authorize the execution of road investment issued on its basis has several effects, i.e. determines the location of a road, approves surveying division, approves construction design and also results in acquisition of a real property by virtue of law by the State Treasury or local government unit, among others. The conducted study revealed that over 3 years, in this mode, the city of Krakow has acquired 31 hectares of land intended for the implementation of road investments. Compensation is determined in separate proceedings based on an appraisal study estimating property value, often at a distant time after the loss of land by the owner. One reason for the lengthy compensation proceedings is challenging the proposed amount of compensation, unregulated legal status of the property as well as imprecise legislation. It is important to properly develop geodetic and legal documentation which accompanies the application for issuance of the decision and is also used in compensation proceedings.

Based on the experiences of a Koreatown scholar, the executive director of a Koreatown nonprofit, and a longtime resident student, the article advocates for greater attention to the complex and dynamic power structures of ethnic enclaves in community-academic partnerships. We discuss the changing landscapes of Koreatown as the global nexus of the Pacific Rim economy, the city of Los Angeles’s urban redevelopment plans, and growing diversity and inequality. Programs that aim to engage effectively with ethnic communities must reassess how knowledge is produced and conveyed, how we structure partnerships within stratified communities, and how to grow from issue-based partnerships to broader communities of interest.

The Postponement

Research Question: This analysis arises from the decision of the current local council of Barcelona regarding the postponement of the sporting mega-event ‘World Roller Games’, due to a lack of a social and sportive implication in this event. This research tries to shed some light on the matter and give evidence to the local council to become the world capital of skating. The research question is to analyse whether non-economic impacts could be relevant enough to organise a mega-event.Research Methods: The methodology is based on the perception and experience of spectators and participants on four main impacts (social, economic, sports city image and sports practice) using a survey from a National Roller Skating Championship in Spain, considering that this profile of respondents have a better knowledge of the current situation of this sport.Results and Findings: There are positive expected future consequences of this mega-event to be held in Barcelona in social and sportive terms. We can also conclude that the local council must still introduce some social and sportive policies in the city in order to improve the chances of success in social, sports practice and sportive brand image development.Implications: It is demonstrated that a mega-event should not be seen purely from a perspective of business generation, especially with minority sports like roller skating. There is a clear opportunity to develop social and sportive practice initiatives that can push social cohesion throughout the city thanks to a mega-event such as this one.
