Article
Full-text available
Monitoring change in informal settlements remains a critical challenge, particularly in data-scarce contexts across the Global South. While satellite remote sensing provides strong temporal coverage, conventional approaches for mapping the built environment often rely on very high-resolution imagery or LiDAR, which lack consistent temporal availabi...

Background Spatial accessibility to healthcare is a critical factor in ensuring equitable health outcomes. While studies on a global, continental, and national level exist, our understanding of intra-urban differences, particularly between formal and informal areas within cities in sub-Saharan Africa, remains limited. Methods This study integrates...
Article
Full-text available
Accurate population data is crucial for assessing exposure in disaster risk assessments. In recent years, there has been a significant increase in the development of spatially gridded population datasets. Despite these datasets often using similar input data to derive population figures, notable differences arise when comparing them with direct gro...
Chapter
This chapter presents a concise synthesis of recent research efforts, emphasizing the combined use of ecosystem services and landscape metric concepts for quantifying provision, quality, and accessibility to ecosystem services as indicators of socio-ecological well-being in deprived urban areas in the Majority World. Such analyses are challenging d...

Purpose: Spatial accessibility to health-care is a critical factor in ensuring equitable health outcomes. While studies on a global, continental, and national level exist, our understanding of intra-urban differences, particularly between formal and informal areas within cities in sub-Saharan Africa, remains limited. Methods: This study integrates...
Article
Closing delivery units increases travel time for some women. Whether increased travel time is associated with maternal outcomes is important for understanding the consequences of such closures. Previous studies are limited in measuring travel time and restricted to the outcome of caesarean section. Our population-based cohort includes data from th...

Denna rapport, som redovisar del 2 av projektet Social sårbarhet för klimatrelaterade hot, syftar till att ta fram ett generellt sårbarhetsindex för Sverige, men också specifika index för tre olika naturhot: översvämning (älv respektive kust), skogsbrand och ras/skred/erosion. För dessa specifika index har sårbarheten kombinerats med en bedömd expo...

Att förstå och sätta mått på sårbarheter hos människor och samhälle är centralt för att reducera risker. I denna rapport utforskas social sårbarhet för olika klimathot i Norden i tre delar: en litteraturstudie av den vetenskapliga kunskapen i en nordisk kontext, en sammanställning av grå litteratur inom området, och ett speciellt fokuskapitel som b...
Article
Full-text available
Rapid urbanization in developing countries often results in uncontrolled urban growth. In order to support sustainable urban development, reliable and up-to-date information on urban land cover changes and their environmental impact is needed. In this study, we aim at evaluating the potential of Sentinel-2 (S-2) Multispectral Instrument (MSI) data...

Cloudburst flash floods cause big casualties and economic losses. This study primarily investigated if a cloudburst catastrophe (cat) model could be constructed to meaningfully assess such a hazard, exposure and vulnerability in Swedish urban context. Rainfall intensity was used directly as hazard measure, bypassing hydraulic water-level modelling,...

Studien har tagit fram ett sårbarhetsindex på kommunal nivå i Sverige, baserat på 37 socio-ekonomiska variabler. Metoden som utvecklats i USA bygger på statistisk analys (PCA) och visualisering i ett GIS. Resultaten visar på tydliga regionala skillnader för social sårbarhet. Metoden behöver fortsatt utveckling, med studier för att öka förståelsen f...

Full-text available
Introduction: Over the last decade, a number of delivery units have been closed in Sweden, justified by both economic incentives and patient safety issues. However, concentrating births to larger delivery units naturally increases travel time for some parturient women, which may lead to unintended negative consequences. We aimed to investigate the...

In Europe, flash floods are one of the most significant natural hazards, causing serious risk to life and destruction of buildings and infrastructure. The intense rain causing those floods has a few different names, however, with very similar meaning. The term chosen in this study, ‘cloudburst’, was introduced by Woolley (1946) as “…a torrential do...

Full-text available
Social vulnerability is mostly described as specific social inequalities in the context of a disaster. Following this understanding, empirical research focuses on the unequal exposure of different groups to disasters and/or on the unequal capacities of groups to anticipate, cope and recover from the impact of a hazard. Although social vulnerability...

Genom en litteraturstudie identifierades ett flertal olika metoder som kan användas för att uppskatta, mäta och modellera oskyddade trafikanters rörelsemönster. En utvärdering och jämförelse av metodernas pålitlighet och lämplighet för framtida implementering i Sverige är dock svår i dagsläget på grund av stora skillnader i studiernas ansatser. Fra...

Objectives Early defibrillation in out-of-hospital cardiac arrest (OHCA) is of importance to improve survival. In many countries the number of automated external defibrillators (AEDs) is increasing, but the use is low. Guidelines suggest that AEDs should be installed in densely populated areas and in locations with many visitors. Attempts have been...
