    Can Geoinformation Help to Better Protect Informal Settlements? - A Concept For the City of Medellín

    Gi4DM 2019 – GeoInformation for Disaster Management, vol. XLII-3/W8

    2019

    DOI: 10.5194/isprs-archives-XLII-3-W8-115-2019

    Abstract anzeigen

    New contributions to disaster research need to address the increasing vulnerability of informal settlements in a changing climate situation. Informal settlements are frequently built in hazardous areas and are often left out of traditional disaster risk management concepts. Hence, formal and informal societal structures, as well as technical systems to warn against, handle or mitigate natural hazards, need to evolve. Within the project Inform@Risk we are addressing these issues based on a case study in Medellín (Colombia). Here, as a result of civil conflicts informal dwellings were partly constructed by people displaced from rural areas. They are mainly located in the urban peripheral areas along steep and unstable slopes, where the resettlement of all inhabitants at risk of landslides is unfeasible. This contribution presents the technical infrastructure and the concept to incorporate geodata from different sources in an integrated landslide early warning system for some selected informal settlements of Medellin. Special attention is given to possibilities on how building societal institutions, supported by information systems, increases local resilience. Using geoformation as a basis, we will combine classical participatory planning methods with digitally assisted concepts. These include combining satellite and UAS based remote sensing data with terrestrial sensor networks, crowd sourcing and citizen science to collect volunteered geographic information about the settlement and its environmental parameters, as well as distribute this information and disseminate warnings to the local population.

    Assessing Middle and Low Voltage Grid Requirements in Bavaria for the Decades to Come

    Shaping a Sustainable Energy Future: 9th Colloquium of the Munich School of Engineering (August 1, 2019)

    2019

    Abstract anzeigen

    Increased urbanization and rural depopulation processes are going to produce a high impact on the future electric grid. The impact of these developments on the shape and characteristics of the electricity transmission and distribution systems is however today not discussed as much as the transition to renewable energies. Current research dedicated to electrical grids focuses on the integration of renewables and the related necessary measures to increase stability and reliability. Topics such as the changes in the shape and length of grid as well as redundant infrastructure issues due to demographic changes are barely studied in previous literature. The present work is a pioneer attempt to address these issues using a spatially explicit approach for the state of Bavaria in Germany. The main consequence emerging from depopulation is not only the increase on size and number of very low populated regions but also growing city-sizes, which up to now already have difficulties of being supplied with sufficient energy. Especially the difference in needs for the electricity grid length per person is going to be even more pronounced than already today. The resulting costs per person to provide everyone with a reliable electricity supply will diverge similarly between urbanized and rural regions. The medium and low voltage grids should be capable of delivering sufficient electricity to users and simultaneously allow the integration of distributed renewable generation installations. While data for analysing the transmission systems (high voltage grids) are widely available, spatial and attribute data of the medium and mainly the low voltage grids are scarce. The first step for the analysis of urbanization and rural depopulation effects on the future Bavarian low and medium voltage grid therefore is the estimation of todays’ electric grid. The present study proposes a method that relies on a) a data set that estimates the topology of the medium and low voltage grids of Bavaria (Germany) based on a minimum spanning tree principle, and b) data from the LUISA territorial modelling platform of the European Commission to calculate grid requirements for the years 2030 and 2050. Two alternative paths are proposed to carry out grid requirement estimations. The first is based on population data and the second on land use data. Grid length typologies are created based on population thresholds or land use types for 2010. The same typologies are afterwards used to extrapolate grid requirements for the future, which follow the population and land use changes of the LUISA data set. The future estimations are therefore in conformity with the forecasts utilized by the European Commission. As a reference base map for comparing grid estimations based on population or land use clusters, the length of the grid calculated based on a) is cumulated for each square kilometer so that the resolution and extend match the LUISA data for Bavaria (the map on the left is the reference map for the medium voltage grid). Results show that when estimating the current electricity grid based on land use clustering, it is not possible to get close to the beforehand calculated reference map. Using population density clusters on the other hand, makes it feasible to estimate the current electric grid based on mean or median grid lengths per cluster category. When comparing statistics as well as the resulting maps, the best method to produce a grid map based on clusters, is when using the median grid length per population cluster category (e.g. map on the right for the medium voltage grid). When using the mean of each category, the results seem not to be as precise. In the particular case of Bavaria, the forecast shows that total grid length requirements will decrease until 2030 and 2050. In rather urbanized regions, the grid needs to be prepared for expansions, while in rural regions existent grid infrastructure will become unnecessary. Hot-spots of such changes can be located using the results of the presented methodology.

    This paper argues that a digital infrastructure is vital to the work of cultural institutions today. In order to develop a well running system for smaller museums, which are hardly ever center of focus of donating companies and sponsors, we develop four measures, an integrated content management and digital signage system, an application for smart phones and a 3D city model, that will allow the visitors to connect with the city's history, virtually and physically.

    The effects of digitization on social coexistence have been a subject of controversynot only since the increased use of social media for political campaigns. Digital platforms are also being developed which,from the perspective of spatial planning and geography,enhancecommunication between administrations and citizens at the local municipal level. These applications are being developedin relation to three areas:(1)the everyday experiences and competences of citizens in dealing with geomedia, especially the use of smartphones; (2)the individual process design for a particularparticipatory case; (3)the desired societal or local political benefit. This paperdeals with these three aspects and discusses five selected examples of how digital participation platforms can be designed to include the use of geomedia. Based on experiences with the proprietary development of the web application PUBinPLAN in particular and on itscomparisonwith other platforms, insights can be derived with regard to success factors as well as to opportunities and risks

    Abstract anzeigen

    The number of electric vehicles is steadily growing and commercial fleet owners follow this trend. However, the charging of fleets has a major impact on the already stressed power grid. To prevent negative impact on the grid, it is necessary to schedule charging processes. This charging scheduling should not only utilize the existing charging infrastructure and the available resources, but it should furthermore allow an optimized charging schedule, e.g. in terms of cost reduction. This scheduling problem is complex and it needs significant information about infrastructure and fleet in order to create a viable charging schedule. However, not all of the relevant information is always available. For this reason, this paper analysis the possibilities to create a charging schedule with missing information. To achieve this, the paper provides a detailed description of the charging scheduling problem for a day ahead planning and the necessary input parameters. It clarifies the influence of the input parameters on the viability and optimality of a charging schedule. On this base, the paper establishes data sets with different degrees of scheduling possibilities. Further, the paper analyses the affectation of missing input parameters on the scheduling and it provides possible solutions to approximate the missing parameters under the proposition to guarantee the viability of a charging schedule.

    DOI: 10.1007/978-3-658-26954-8_11

    Abstract anzeigen

    Betriebsleiter in der Gemeinschaftsverpflegung stehen bei ihren Kalkulationen vor großen Herausforderungen. Sowohl externe Einflüsse als auch der Speiseplan selbst beeinflussen die Zahl der Essensteilnehmer. Die Verkaufsmengen der einzelnen Speisen weisen einen hohen Zusammenhang mit der Zusammenstellung des Speiseplans auf. Die Kalkulation der Einkaufs‐ und Produziermengen basiert in den meisten Gastronomien auf der Expertise und den Erfahrungswerten der Betriebsleiter und Küchenchefs. Ziel dieses Beitrags ist die Entwicklung von Prognosealgorithmen für die Gemeinschaftsverpflegung, um die Kalkulationen von Lebensmitteleinkäufen zu erleichtern und somit den Verlust von Lebensmitteln zu verringern. Dazu werden die Daten aus drei Pilotunternehmen mithilfe von statistischen Datenanalysemethoden untersucht. Es werden Prognosemodelle entwickelt, die die zukünftigen Essensteilnehmerzahlen sowie die Anzahl an benötigten Portionen pro Gericht vorhersagen und damit die Kalkulationen für Küchenleiter erleichtern sollen. Eine Verallgemeinerung der Modelle sichert die Übertragbarkeit auf andere Betriebsgastronomien.

    A spatially explicit assessment of middle and low voltage grid requirements in Bavaria until 2050

    Geoscape, vol. 13, no. 2, pp. 88-97

    2019

    DOI: 10.2478/geosc-2019-0008

    Abstract anzeigen

    The energy transition towards high shares of renewables and the continued urbanization process have a direct and strong impact on the shape and characteristics of the electricity transmission and distribution systems. At the continental and national scale, improved high voltage grids should allow the transmission and balance of electricity from hot-spots of variable renewable energy generation installations to demand centres. At the regional and municipal scale, the medium and low voltage grids should be capable of bringing sufficient electricity to users and allow the integration of distributed renewable generation installations. While data on the transmission systems is widely available, spatial and attribute data of the medium and mainly the low voltage grids are scarce. Additionally, while there are plenty of studies on the requirements of the grid to allow the energy transition, there is very little information on the necessary transformation of the grid due to changes generated by the expected urbanization process. This study relies on a data set that estimates the topology of the medium and low voltage grids of Bavaria (Germany) as well as data from the LUISA territorial modelling platform of the European Commission to calculate key figures of grid requirements depending on population and land use for the current case and the decades to come. Typologies of grid requirements are proposed based on a statistical analysis of population and land use data of each square kilometre of the federal state. These typologies are extrapolated to changes in the structure of settlements that are expected in the years 2030 and 2050. Results are presented using maps with expected absolute values of grid requirements and their temporal changes for each square kilometre of the project area. Grid requirements are expected to increase in cities and to be reduced in most of the rural areas. The largest changes are expected to take place in the suburbs of the major cities.

    Potential Analysis of Hybrid Renewable Energy Systems for Self-Sufficient Residential Use in Germany and the Czech Republic

    Energies, vol. 12, no. 21

    2019

    DOI: 10.3390/en12214185

    Abstract anzeigen

    Independence from the power grid can be pursued by achieving total self-sufficient electricity supply. Such an energy supply model might be particularly interesting for settlements located in rural areas where enough space is available for energy generation installations. This article evaluates how and at what cost electricity demand of residential users across Germany and the Czech Republic could be covered by hybrid renewable energy generation systems consisting of photovoltaics, micro-generation wind turbines and batteries. High-resolution reanalysis data are used to calculate necessary system sizes over a large area by simultaneously accounting for the temporal variability of renewable energy. For every potential location in the research area, the hybrid system requirements for clusters of 50 self-sufficient single-family houses are calculated. The results indicate no general trend regarding the size of the respective technologies, although larger areas where PV-wind power complementarity enables lowering the total system costs and required storage capacities were determined. Assuming that the cluster of households could be constituted and depending on the location, the total installation and operation costs for the proposed systems for a lifetime of 20 years range between EUR 1.8 Million and EUR 5 Million without considering costs of financing. Regions with the lowest costs were identified mainly in the south of Germany.
