The boom of short-term rental (STR) intensifies the debate on overtourism because of some negative effects on destinations. Conversely, the STR was a way out in moments of crisis. Until now, only a few studies extend the analysis outside the limits of individual cities; that's why this case-study research was conducted by the analyses of Airbnb listings and the tourists' spatial distribution in Lisbon Metropolitan Area (LMA). For this purpose, this chapter uses two cartographic tools: 1) Airbnb listing from Inside Airbnb Project of Lisbon and 2) Geotaggers' World Atlas (map of sites that tourists took photos). Also, institutional Lisbon urban planning plans fed this study. Methodologically, combining the selected maps is a way to understand tourism spatial analysis by bringing together data on supply-side (rooms) and demand-side (distribution of tourists). The analysis demonstrates that a time-spatial distribution of visitors and the STR throughout the LMA could contribute to avoiding tourism congestion and proper distribution of economic benefits.

Research Period

During the seven-year research period, the average annual removal was by 3274 m3 higher than the average annual removal prescribed by the existing management plan (MP). The main reason lies in the high amount of salvage felling volume at 55,238 m3 (38.3%) in both the main and the intermediate felling due to oak dieback. The analysis of forest accessibility took into account the spatial distribution of cutblocks (with ongoing felling operations) and the volume of felled timber for two proposed factors: (1) the position of the cutblock and (2) the position of the removal. Cutblock position factor took into account the spatial position of the felling areas/sites, while removal position factor besides the spatial reference took into account the amount of felled timber (i.e., volume) both concerning forest infrastructure network and forest operations. The analysed relative forest openness by using geo-processing workflows in GIS environment showed four types of opening areas in the studied management unit (MU): single-opened, multiple-opened, unopened and opened areas outside of the management unit. Negative effects of the piece-volume law and low harvesting densities on forest operations are highlighted in this research due to high amount of salvage felling particularly in the intermediate felling by replacing timber volume that should have come from thinnings.

Predominant Effect

Aquaponics, the water-reusing production of fish and crops, is taken as an example to investigate the consequences of upscaling a nature-based solution in a circular city. We developed an upscaled-aquaponic scenario for the German metropolis of Berlin, analysed the impacts, and studied the system dynamics. To meet the annual fish, tomato, and lettuce demand of Berlin’s 3.77 million residents would require approximately 370 aquaponic facilities covering a total area of 224 hectares and the use of different combinations of fish and crops: catfish/tomato (56%), catfish/lettuce (13%), and tilapia/tomato (31%). As a predominant effect, in terms of water, aquaponic production would save about 2.0 million m3 of water compared to the baseline. On the supply-side, we identified significant causal link chains concerning the Food-Water-Energy nexus at the aquaponic facility level as well as causal relations of a production relocation to Berlin. On the demand-side, a ‘freshwater pescatarian diet’ is discussed. The new and comprehensive findings at different system levels require further investigations on this topic. Upscaled aquaponics can produce a relevant contribution to Berlin’s sustainability and to implement it, research is needed to find suitable sites for local aquaponics in Berlin, possibly inside buildings, on urban roofscape, or in peri-urban areas.

Spatial Practices

In cities across the United States, groups of mostly men congregate in public and semipublic spaces in hopes of being hired for short-term work. The particular spaces where laborers congregate each day are crucial to their economic and social fortunes, yet to date, there is limited research examining the spatial organization of these sites. In this article, I draw on relational perspectives on the production of space and governmentality practices to examine day-labor hiring spaces in the San Diego Metropolitan Area. Drawing on more than seven years of mixed-methods research, I argue that laborers collectively employ strategic visibility: a set of spatial practices that reduces the potential for conflict and ensures laborers’ continued access to the particular spaces on which their survival depends. This analysis suggests that laborers’ site-selection and spatial practices are driven by pragmatic, economic concerns, rather than fear of interactions with policing agencies and/or anti-immigrant residents.

The tugboat is the vessel that helps to maneuver large ships for berthing and un-berthing operations. To achieve efficient tugboat operations, investigating the features of tugboat activities is of crucial importance. This study aims to use automatic identification system (AIS) data to identify the maneuver services and analyze the characteristics of tugboat activities. A two-stage algorithm is developed to extract the time, locations, and involved tugboats for berthing and un-berthing operations from AIS data. The AIS data from Tianjin port, China, are used in the case study to demonstrate the effectiveness of the proposed method and analyze the pattern of tugboat activities. First, some important features of tugboat jobs are presented, such as the daily number of jobs and the spatial distribution of jobs. Then, a temporal and spatial analysis is conducted to investigate tugboat assignment, service time, tugboat utilization, and locations of berthing and un-berthing operations. The obtained results and implications could shed light on the deployment of tugboat berths, tugboat scheduling, and evaluation of tugboat fleet operation.

We present a collection of small multiple graphics that support analysis and understanding of the geography of labour-market self-containment across London’s 33 boroughs. Ratios describing supply-side self-containment, the extent to which working residents access jobs locally, and demand-side self-containment, the extent to which local jobs are filled by local resident workers, are first calculated for professional and non-professional occupations and encoded directly through geographically-arranged bar charts. The full distribution of workers into-and out-of- boroughs that underpins these ratios is then revealed via Origin-Destination flows maps (OD maps) – sets of geographically-arranged choropleths. In order to make relative and absolute comparison of borough-to-borough frequencies between occupation types, these OD maps are coloured according to signed chi-square residuals: for every borough-to-borough pair, we compare the observed number of flows to access professional versus non-professional jobs against the number that would be expected given the distribution of those jobs across London boroughs. Our geographically-arranged small multiples demonstrate potential for spatial analysis: a rich, multivariate structure is depicted that reflects London’s economic geography and that would be difficult to expose using non-visual means.

The risk induced by landslides on residential infrastructure, transport infrastructure and agricultural land causes problems of local management that need to be solved by reducing negative effects and decrease the frequency of their occurrence. This study followed the development and implementation of a model for identifying the risk induced by landslides through the analysis of spatial occurrence probability for landslides at the administrative territorial unit of Șieu, following the semi-quantitative method governed in Romania by G.D. no 447/2003 and then through the exposure of housing infrastructure at landslides was possible to frame landslides on risk classes. The entire approach was based on GIS spatial analysis, creating a specific detailed database of causing and triggering factors of landslides and not at least, a database for risk receptors, in this study, represented by the constructions of villages associated with the studied administrative territorial units. The final result of the model highlights the framing of constructions on qualitative risk classes at landslides, revealing the elements of infrastructure that need post and pre event measures of protection.

Positive Effects

Purpose – This paper tries to explore the possibilities of developing sustainable, community-based tourism (CBT) in Boa Vista in Cape Verde, Africa. Island territories are generally considered preferential tourist destinations. However, the negative effects of tourism in these destinations should not be overlooked, among them environmental concerns and impacts on the culture of the island’s inhabitants. The development of CBT takes on special relevance, as it based on planning schemes in conjunction with the local community who share the positive effects derived from tourism. Design/methodology/approach – The methodology used consisted in designing two surveys: one focusing on the supply side and another on the demand side of tourism to define and analyse the current status of this sector in Boa Vista. The survey on tourism supply was distributed among a panel of experts formed by tourism service providers located in Boa Vista. The statistical results of the responses and the discussion carried out by the panel of experts permitted the development of a SWOT matrix. The survey on demand was administered to foreign tourists in different parts of the island. A total of 202 valid surveys were obtained. Findings – The main results of the fieldwork are twofold. On the supply side of tourism, the community is making an enormous effort to actively participate in the development of sustainable tourism, efforts which are often constrained by the geographical barriers of Boa Vista (sandy soil, poor accessibility to other islands) and the institutional and political situation of the island. As regards the demand side of tourism, the vast majority of tourists stay at the island’s all-inclusive resorts, whereas few tourists require the services provided by the community, mainly because they are unaware that such services exist. Originality/value – Certain island destinations are more appropriate for tourists wishing to flee mass tourism enclaves due to their natural environment, relative isolation and the traditional culture of their inhabitants. For this reason, it is important to develop a CBT model for these destinations in which initiatives are planned in conjunction with members of the local community who participate in decision-making processes and benefit equally from the positive effects of tourism. Although several case studies have been reported in the research on CBT initiatives, few studies have been carried out on CBT in island territories. This is the main contribution in this paper.

Efficient Power

Integrated Resource Strategic Planning (IRSP) is an extension of Integrated Resource Planning (IRP) at the national level for power planning. It provides a new theoretical foundation for the implementation of demand-side management (DSM) in the deregulated conditions. In this paper, IRSP model for power planning is proposed. In the model, both supply-side and demand-side resources as efficient power plant (EPP) are considered in the optimization process. A case study for the power planning in the United States is presented in the paper. The results indicate that, comparing with traditional planning the IRSP model can not only achieve the minimum total costs, but also reduce the supply-side capacity installation and the related pollution emissions.
