Abstract. How can FOSS GIS support generative economy processes in small settled communities? The paper answers this question by proposing a toolbox made up of specific open geospatial data that can be processed through FOSS GIS. These data consist of specific maps, accompanied by numerical values.The information collected is intended to lay the foundations for an open-access manual of procedures to support the creation of an open database. This manual, currently under development, is created within a research funded by the Department of Architecture and Urban Studies of the Politecnico di Milano and is an integral part of an experimental game aimed at supporting students in the development of local self-sustainability scenarios.The manual is called the GED Toolkit. The acronym GED stands for Generative Environmental Design, with this term we refer to an approach to the design of the anthropized environment oriented towards the development of generative economies.The paper presents good practices, measuring their consistency with Generative Economy Principles through resource and impacts mapping. These are useful in the first place to understand the systemic features of the practice itself and the relationship with the territory that hosts it, and secondly to verify the possible transferability to other contexts.

Open access geospatial data represent a range of metrics relevant to global human population mapping at fine spatial scales. Detailed and contemporary spatial datasets that accurately describe population distributions are vital in order to measure impacts of population growth, monitor change, and plan interventions. To construct such datasets the harmonisation of geospatial data layers is a prerequisite because layer specifications differ widely. <br><br> To this end the WorldPop Project is producing an open access archive of 3 and 30 arc-second (~&amp;thinsp;100&amp;thinsp;m and ~&amp;thinsp;1&amp;thinsp;km, respectively) resolution gridded data in a predominantly open source environment, using OSGEO4W utilities. Five tiled raster datasets form the basis of the archive: (i) Viewfinder Panoramas topography clipped to CIESIN national level administrative coastlines; (ii) a matching ISO 3166 country identification grid; (iii) country area; (iv) pixel area; (v) and slope layer. Further layers will include transport networks, landcover, urban extent, nightlights, climate, travel time to major cities, forest stand change, livestock densities, vegetation indices, and waterways. We here describe the base datasets and the production methodology in development. The alpha version of the archive can be downloaded both from the WorldPop Dataverse Repository and the WorldPop Project website. The improved and expanded beta version of the archive is in development for release next year, and will offer significantly improved standardisation of country boundaries, and inland water boundaries (forthcoming), to global census unit data.

Achieving universal access to electricity is a development challenge many countries are currently battling with. The advancement of information technology has, among others, vastly improved the availability of geographic data and information. That, in turn, has had a considerable impact on tracking progress as well as better informing decision making in the field of electrification. This paper provides an overview of open access geospatial data and GIS based electrification models aiming to support SDG7, while discussing their role in answering difficult policy questions. Upon those, an updated version of the Open Source Spatial Electrification Toolkit (OnSSET-2018) is introduced and tested against the case study of Malawi. At a cost of $1.83 billion the baseline scenario indicates that off-grid PV is the least cost electrification option for 67.4% Malawians, while grid extension can connect about 32.6% of population in 2030. Sensitivity analysis however, indicates that the electricity demand projection determines significantly both the least cost technology mix and the investment required, with the latter ranging between $1.65–7.78 billion.

Abstract Despite the explosion of geospatial data collected on water points, there have been relatively few efforts to date to use these data to understand the correlates and potential causes of water point breakdowns. We add to this literature by coding open-ended responses around functionality status in the open-access WPDx (Water Point Data Exchange) database. We code responses into 41 different categories of functionality problems for 244,075 water points from 25 countries in Africa, Asia and Central America, though we narrow our analysis to 41,716 points in six countries. We find that descriptions of technical breakdowns or problems are most common, though concerns about water resources and water quality feature prominently. We also find that 7% of records in our analysis subset spontaneously mention concerns over vandalism or theft, something which has received relatively little attention in the sector. Information on user financial contributions is mostly omitted by uploaders to WPDx, but we find that users are not contributing at all in 40% of the 96,651 water points with these data. Our results should be interpreted cautiously considering the obvious selection and subjectivity concerns, but the analysis highlights the potential benefits of coordinating an augmented data collection standard.

Zusammenfassung. Psychische Störungen können über die ganze Lebensspanne auftreten. Strukturierte klinische Interviews sind zentrale Hilfsmittel für ihre rasche, zuverlässige und umfassende Diagnostik. Im deutschsprachigen Raum stehen mit den Verfahren der DIPS-Familie Interviews zur Diagnostik psychischer Störungen über die gesamte Lebensspanne zur Verfügung, die seit den 90er Jahren regelmäßig aktualisiert wurden. Ihre Reliabilität, Validität und Akzeptanz wurde wiederholt in großen Stichproben aus ambulanten, stationären und Forschungssettings überprüft. Die Einführung des DSM-5 erforderte eine umfassende Überarbeitung der DIPS-Interviews, deren wesentliche Merkmale dargestellt werden. Um die breitere Verwendung von strukturierten klinischen Interviews zu fördern, werden die Verfahren der DIPS-Familie neu als „Open Access-Dokumente“ zur Verfügung gestellt. Abschließend werden weitere Entwicklungen zu Training, Dissemination und Computerisierung im Ausblick angesprochen.
