O despovoamento das áreas rurais do interior de Portugal, com os sucessivos decréscimos da sua população residente, é um fenómeno que não é novo, sendo as suas causas conhecidas. Na sequência de trabalhos anteriores sobre o desaparecimento estatístico dos lugares, este estudo efectua uma análise aos lugares da faixa raiana do território de Portugal Continental. Comprova-se que também aqui se regista um grau de desaparecimento estatístico de lugares que no espaço de duas gerações pode vir a ocorrer em 44% dos lugares atualmente existentes. || The depopulation of rural areas in the interior of Portugal, with the successive decreases in its resident population, is a phenomenon that is not new, its causes being known. Following previous work on the statistical disappearance of places, this study analyzes the places in the border strip of the territory of mainland Portugal. It can be seen that this region also registers a degree of statistical disappearance of places that in the space of two generations can reach 44% of the places currently in existence.

Data obtained through Volunteered Geographical Information (VGI) have gradually been used to monitor and support planning mainly in urban contexts. Regarding recreational activities in peri-urban green and natural areas, VGI has been used to map, measure use intensity, profile users, and evaluate their preferences and motivations. Given their extensive use, it is now worthwhile to assess the value of VGI data to (1) compare recreational uses, profile users and map recreational activities in different contexts (metropolitan vs. rural areas), and (2) evaluate outdoor and adventure tourist products such as Grand Routes (GR). Data from former GPSies (AllTrails nowadays), one of the most popular web-share services, were used to assess recreational uses in Lisbon Metropolitan Area (LMA) and southwest Portugal (SWPT). A set of 22,031 tracks of “on foot” and “on wheels” activities, submitted by 3297 national and foreign users, covering 12 years, was analysed within a GIS modelling environment. Results indicate that, although there are many more submissions in the LMA, the influence of foreigners in the SWPT is higher (11% vs. 19%). The existing GR in SWPT concentrates the foreign use for hiking (71% of foreign vs. 28% of national users), demonstrating its attractiveness. For the favourite activity in both areas—Mountain biking—results show a higher spatial dispersion, yet part of the activity in SWPT still conforms to the GR (16% of foreign and 20% of national use). This study proves other applications for VGI, showing its usefulness for assessing recreational uses in both metropolitan and rural areas. Spatial knowledge about recreational uses is a valuable tool to evaluate and monitor such activities, and to know what users like to do, and where, and is also useful information when designing recreational products considering their tourist potential, thus adding value to these offers.

Urban solar potential for vehicle integrated photovoltaics

Integrating solar photovoltaics in electric vehicles can reduce operating costs and extend the driving range. It is particularly appropriate for urban mobility due to the relatively short typical daily travels of urban vehicles. However, shadowing cast by buildings will reduce the solar irradiation falling on the vehicle, reducing its PV generation. This study assesses the solar potential of onboard solar for roads and urban parking using data in a geographical information system for the case study of Lisbon. Results show that annual losses due to shadowing may reach 25% for roads and over 50% for urban parking spaces. Nevertheless, despite these losses, the annual solar extended range for onboard solar vehicles is between 10 and 18 km/day/kWp, thus significantly reducing charging needs.
