Title Night light intensity and women's body weight: Evidence from Nigeria Type Journal Article
Year 2018 Publication Economics and Human Biology Abbreviated Journal Econ Hum Biol
Volume 31 Issue Pages 238-248
Keywords Remote Sensing; Human Health; Adolescent; Adult; Body Mass Index; *Body Weight; Cross-Sectional Studies; Female; Health Surveys; Humans; Lighting/*statistics & numerical data; Middle Aged; Nigeria/epidemiology; Obesity/epidemiology; Overweight/*epidemiology; Prevalence; *Urbanization; Young Adult; *Bmi; *Nigeria; *Night light; *Obesity; *Overweight; *Urbanization
Abstract The prevalence of overweight and obesity are increasing in many African countries and hence becoming regional public health challenges. We employ satellite-based night light intensity data as a proxy for urbanization to investigate the relationship between urbanization and women's body weight. We use two rounds of the Demographic and Health Survey data from Nigeria. We employ both nonparametric and parametric estimation approaches that exploit both the cross-sectional and longitudinal variations in night light intensities. Our empirical analysis reveals nonlinear relationships between night light intensity and women's body weight measures. Doubling the sample's average level of night light intensity is associated with up to a ten percentage point increase in the probability of overweight. However, despite the generally positive relationship between night light intensity and women's body weight, the strength of the relationship varies across the assorted stages of night light intensity. Early stages of night light intensity are not significantly associated with women's body weight, while higher stages of nightlight intensities are associated with higher rates of overweight and obesity. Given that night lights are strong predictors of urbanization and related economic activities, our results hint at nonlinear relationships between various stages of urbanization and women's body weight.

Title Licht über Wien VI Type Journal Article
Year 2018 Publication Abbreviated Journal
Volume Issue Pages
Keywords Skyglow
Abstract Im Zentrum Wiens sättigt die Erhellung der Nacht, am Stadtrand sinken die jährlichen Zuwächse, wäh-rend im Abstand von 36 Kilometern (Großmugl) die Nächte um 10 % pro Jahr heller werden.Der Gesamtaufwand der Wiener Lichtglocke liegt 2018 bei 37 MW. Der Verlauf von 2011 bis 2018 zeigt ein deutliches Lichtmaximum um 2014 und 2015. Danach stellen wir einen allmählichen Rückgang fest.Der Verlauf der Lichtglocke und noch deutlicher jener der Einzelstationen zeigt signifikante Schwankun-gen von Jahr zu Jahr. Zur Aufklärung der Ursachen, die weder astronomisch noch meteorologisch sind, wur-den monatliche Analysen des Lichtmessnetzes mit Daten des Luftmessnetzes der Wiener MA 22 kombiniert. Die natürliche Variation über das Jahr wurde genutzt, um Zusammenhänge zwischen den Monatsmedianen von Luftfeuchtigkeit und Feinstaub mit jenen der Globalstrahlungsdaten zu suchen.Von 2016 bis 2018 korrelieren die Globalstrahlungswerte mit der relativen Luftfeuchtigkeit und den Feinstaubwerten (PM10 und PM2,5). Die engste Beziehung besteht auf der Kuffner-Sternwarte, wo eine Verdoppelung der Luftfeuchtigkeit statistisch von einer Verzehnfachung der Globalstrahlung begleitet wird. Die gefundenen Relationen sind über einen Faktor 100 in der Globalstrahlung äußerst robust und die Koeffizienten der Relationen sind an allen Stationen sehr homogen.Damit stehen gut bestimmte Zusammenhänge zwischen der Luftgüte und dem Zustand der klaren Atmo-sphäre zur Verfügung. Das wird es erlauben, Lichtmessnetze auf Standardatmosphären zu beziehen und damit eine wesentlich bessere Vergleichbarkeit der Daten zu unterschiedlichen Zeitpunkten herzustellen.- 130 Gigawattstunden Jahresaufwand für die Wiener Lichtglocke- 8 Jahre Vermessung der Lichtglocke zeigen Ansätze eines Rückgangs der Lichtflut- Mehr Feinstaub bewirkt überproportional mehr Lichtverschmutzung

Title Fluctuations in anthropogenic nighttime lights from satellite imagery for five cities in Niger and Nigeria Type Journal Article
Year 2018 Publication Scientific Data Abbreviated Journal Sci Data
Volume 5 Issue Pages 180256
Keywords Remote Sensing
Abstract Dynamic measures of human populations are critical for global health management but are often overlooked, largely because they are difficult to quantify. Measuring human population dynamics can be prohibitively expensive in under-resourced communities. Satellite imagery can provide measurements of human populations, past and present, to complement public health analyses and interventions. We used anthropogenic illumination from publicly accessible, serial satellite nighttime images as a quantifiable proxy for seasonal population variation in five urban areas in Niger and Nigeria. We identified population fluxes as the mechanistic driver of regional seasonal measles outbreaks. Our data showed 1) urban illumination fluctuated seasonally, 2) corresponding population fluctuations were sufficient to drive seasonal measles outbreaks, and 3) overlooking these fluctuations during vaccination activities resulted in below-target coverage levels, incapable of halting transmission of the virus. We designed immunization solutions capable of achieving above-target coverage of both resident and mobile populations. Here, we provide detailed data on brightness from 2000-2005 for 5 cities in Niger and Nigeria and detailed methodology for application to other populations.

Title Roadway Lighting Retrofit: Environmental and Economic Impact of Greenhouse Gases Footprint Reduction Type Journal Article
Year 2018 Publication Sustainability Abbreviated Journal Sustainability
Volume 10 Issue 11 Pages 3925
Keywords Economics; Lighting
Abstract Roadway lighting retrofit is a process continuously developed in urban environments due to both installation aging and technical upgrades. The spectacular example is replacing the high intensity discharge (HID) lamps, usually high pressure sodium (HPS) ones, with the sources based on light-emitting diodes (LED). The main focus in the related research was put on energy efficiency of installations and corresponding financial benefits. In this work, we extend those considerations analyzing how lighting optimization impacts greenhouse gas (GHG) emission reduction and what are the resultant financial benefits expressed in terms of emission allowances prices. Our goal is twofold: (i) obtaining a quantitative assessment of how a GHG footprint depends on a technological scope of modernization of a city HPS-based lighting system; and (ii) showing that the costs of such a modernization can be decreased by up to 10% thanks to a lowered CO 2 emission volume. Moreover, we identify retrofit patterns yielding the most substantial environmental impact.

Title Experimental Study of the Levels of Street Lighting Using Aerial Imagery and Energy Efficiency Calculation Type Journal Article
Year 2018 Publication Sustainability Abbreviated Journal Sustainability
Volume 10 Issue 12 Pages 4365
Keywords Remote Sensing; Lighting
Abstract This article describes an innovative method for measuring lighting levels and other lighting parameters through the use of aerial imagery of towns and cities. Combined with electricity consumption data from smart electricity meters, it was possible to measure the energy efficiency of public lighting installations. The results of this study also confirmed that lighting measurements, installation material, luminaire position, and electricity consumption data can be easily integrated into geographic information systems (GIS). The main advantage of this new methodology is that it provides information about lighting installations in large areas in less time than more conventional procedures. It is thus a more effective way of obtaining the data required to calculate the energy efficiency of lighting levels and electricity consumption. There is even the possibility of generating street lighting maps that provide local administrations with up-to-date information regarding the status of public lighting installations in their city. In this way, modifications or improvements can be made to achieve greater energy savings and, if necessary, to correct the distribution or configuration of public lighting systems to make them more efficient and sustainable. This research studied levels of street lighting and calculated the energy efficiency in various streets of Deifontes (Granada), through the use of aerial imagery.
