Assessing the suitability of settlement delineations for monitoring infilling
21 st century urbanisation features not only the growth of city populations but also the emergence of densification (infilling) as significant trends in urban development. While urban sprawl has long been acknowledged for its adverse effects, understanding densification remains challenging due to inadequate empirical and statistical frameworks. This study investigates the suitability of different geospatial datasets and methods for delineating se…
Reflecting on the practice of citizen science projects for cities – the case of ‘Colouring Dresden’ in Germany
Citizen Science Projects (CSP) are emerging as innovative approaches to urban research and practice. This paper reports on the data-driven CSP ‘Colouring Dresden’ in Germany through the lens of Critical Data Studies (CDS). CDS-scholars urge CSP-partners to be aware of the ‘political nature’ of their projects. However, this claim requires some conceptual specification. In case of ‘Colouring Dresden’, the paper adopts a micro-oriented approach that…
Cost-effectiveness of a simplified acute malnutrition program
Acute malnutrition (AM) causes large loss of life and disability in children in Africa. Researchers are testing innovative approaches to increase the efficiency of treatment programs This paper presents results of a cost-effectiveness analysis of one such program in the Democratic Republic of the Congo (DRC) based on a secondary analysis of a randomized controlled trial Optimizing Treatment for Acute Malnutrition (OptiMA), conducted in DRC in 201…
Prediction of residential and non-residential building usage in Germany based on a novel nationwide reference data set
Building usage is an important variable in modelling the energetic, material and social properties of a building stock. Gathering this data on large geographical scale, and in the necessary temporal and spatial resolution, that means, on building level, is a challenging task. Machine Learning algorithms like Random Forest have proven useful in predicting building-related features in the past but often resort to training sets of limited geographic…
Leveraging tuberculosis programs for future pandemic preparedness
Worldwide, COVID-19 has decimated healthcare systems and highlighted the pressing need to ensure resilience for future pandemics. Given the almost 30% likelihood of another respiratory disease similar to COVID-19 manifesting in the next 10 years, it is imperative to prioritize pandemic preparedness in the immediate future. To this end, tuberculosis (TB) and its management share many similarities to respiratory disease protection, offering an oppo…
Global Burden and Trends of Norovirus-Associated Diseases From 1990 to 2019
Introduction: As an important pathogen causing diarrheal diseases, the burden and change in the death rate of norovirus-associated diseases (NADs) globally are still unknown. Methods: Based on global disease burden data from 1990 to 2019, we analyzed the age-standardized death rate (ASDR) of NADs by age, region, country, and Socio-Demographic Index (SDI) level. The discrete Poisson model was applied in the analysis of NADs' spatiotemporal aggrega…
Comparative Study on Matching Methods for the Distinction of Building Modifications and Replacements Based on Multi-Temporal Building Footprint Data
We compare different matching methods for distinguishing building modifications from replacements based on multi-temporal building footprint geometries from 3D city models. Manually referenced footprints of building changes were used to determine which thresholds are suitable for distinction. In addition, since the underlying LoD1 (Level of Detail 1) data is highly accurate, randomly generated position deviations were added to allow for transfera…
Geospatial Modeling Approaches to Historical Settlement and Landscape Analysis
Landscapes and human settlements evolve over long periods of time. Land change, as one of the drivers of the ecological crisis in the Anthropocene, therefore, needs to be studied with a long-term perspective. Over the past decades, a substantial body of research has accumulated in the field of land change science. The quantitative geospatial analysis of land change, however, still faces many challenges; be that methodological or data accessibilit…

Do land policies make a difference? A data-driven approach to trace effects on urban form in France and Germany
Against the backdrop of rapidly expanding urban structures, land policies in many countries have been adapted to contain and redirect growth to existing urban structures. However, obstacles remain to measure the effects of policies. In the meantime, geoinformation technologies have given rise to a wide range of approaches to measure and describe urban form. Nevertheless, its application for the assessment of land policy has a high, but not yet fu…
Automatic Delineation of Urban Growth Boundaries Based on Topographic Data Using Germany as a Case Study
Urban Growth Boundary (UGB) is a growth management policy that designates specific areas where growth should be concentrated in order to avoid urban sprawl. The objective of such a boundary is to protect agricultural land, open spaces and the natural environment, as well as to use existing infrastructure and public services more efficiently. Due to the inherent heterogeneity and complexity of settlements, UGBs in Germany are currently created man…
Mapping Public Urban Green Spaces Based on OpenStreetMap and Sentinel-2 Imagery Using Belief Functions
Public urban green spaces are important for the urban quality of life. Still, comprehensive open data sets on urban green spaces are not available for most cities. As open and globally available data sets, the potential of Sentinel-2 satellite imagery and OpenStreetMap (OSM) data for urban green space mapping is high but limited due to their respective uncertainties. Sentinel-2 imagery cannot distinguish public from private green spaces and its s…
Utilization patterns, outcomes and costs of a simplified acute malnutrition treatment programme in Burkina Faso
Access to treatment for acute malnutrition remains a challenge, in part due to the fragmentation of treatment programmes based on case severity. This paper evaluates utilization patterns, outcomes and associated costs for treating acute malnutrition cases among a cohort of children in Burkina Faso. This study is a secondary analysis of a proof-of-concept trial, called Optimizing treatment for acute Malnutrition (OptiMA), conducted in Burkina Faso…
Urban infill development potential in Germany
Limiting land take is an important sustainability target. To this end, infill development is a primary strategy. To implement this strategy, policy-makers need a reliable knowledge base on infill development potential (IDP), such as brownfields, vacant lots and underused lots. This study presents the results of the first comprehensive national survey of IDP in Germany. Almost 12% of German municipalities were contacted by questionnaire. In contra…

Estimating the Population Size of People Who Inject Drugs in Malaysia for 2014 and 2017 Using the Benchmark-Multiplier Method
Background: As hepatitis C elimination efforts are launched, national strategies for screening and treatment scale-up in countries, such as Malaysia, must be designed and implemented. Strategic information, including estimates of the total number of patients chronically-infected with hepatitis C virus (HCV) and the size of key populations, such as people who inject drugs (PWID), is critical to informing these efforts. For Malaysia, the estimate o…

Transitioning financial responsibility for health programs from external donors to developing countries
The investment case for hepatitis B and C in South Africa
Even though WHO has approved global goals for hepatitis elimination, most countries have yet to establish programs for hepatitis B and C, which account for 320 million infections and over a million deaths annually. One reason for this slow response is the paucity of robust, compelling analyses showing that national HBV/HCV programs could have a significant impact on these epidemics and save lives in a cost-effective, affordable manner. In this co…

Reaching the global target to reduce stunting
Childhood stunting, being short for one's age, has life-long consequences for health, human capital and economic growth. Being stunted in early childhood is associated with slower cognitive development, reduced schooling attainment and adult incomes decreased by 5-53%. The World Health Assembly has endorsed global nutrition targets including one to reduce the number of stunted children under five by 40% by 2025. The target has been included in th…
Overcoming challenges to sustainable immunization financing
Over the 5-year period ending in 2018, 16 countries with a combined birth cohort of over 6 million infants requiring life-saving immunizations are scheduled to transition (graduate) from outside financial and technical support for a number of their essential vaccines. This support has been provided over the past decade by the GAVI Alliance. Will these 16 countries be able to continue to sustain these vaccination efforts? To address this issue, GA…
Immigration, land transfer and tenure changes in Divo, Ivory Coast, 1940-80
Opening ParagraphThe relationship between land tenure forms and the twentieth-century transformation of agriculture throughout much of Africa from a strong subsistence to a market orientation - and from food crop production to predominantly export crop production - is a topic of great importance both to Africanists and to policy-makers. From a scholarly perspective, contemporary Africa presents an unusual opportunity to study dramatic changes in …

The Ivory Coast Economic 'Miracle
The pattern of rapid economic growth in the Ivory Coast since the early 1950s has been frequently described with some hyperbole, by foreign experts and Ivorian politicians, as an economic 'miracle'. While most African nations, with the exception of the oil-exporters, have taken a rough ride on the economic roller-coaster during the past two decades, and while some like Guinea, Ghana, and Uganda, have followed a steadily downward trajectory, the e…
