Title Nocturnal resting behaviour in urban great tits and its relation to anthropogenic disturbance and microclimate Type Journal Article
Year 2019 Publication Behavioral Ecology and Sociobiology Abbreviated Journal Behav Ecol Sociobiol
Volume 73 Issue 2 Pages
Keywords Animals
Abstract The ecological novelty of urbanisation poses many challenges to animals. We investigated whether anthropogenic disturbance (artificial light at night and noise) and abiotic factors in cities (temperature and humidity) predict nocturnal activity and rest in free-living urban great tits (Parus major). Our study is the first to relate nocturnal rest in wild birds to levels of noise pollution during the night, an issue that has been shown to be particularly damaging to human health. Unlike previous work on nocturnal behaviour of urban birds, we considered the combined effect of anthropogenic disturbance and urban microclimate to acknowledge that the umwelt of an animal is composed of multiple environmental variables. Using infrared cameras, we observed the nocturnal resting behaviour as a proxy for sleep in 17 birds in nest boxes deployed across the city of Munich, Germany. Although we found marked differences in resting behaviour between individuals, this variation was not related to the measured environmental factors. This finding contrasts earlier studies that reported nocturnal resting behaviour of birds to vary with temperature and light exposure. Although we did not find evidence that urban environmental factors disrupt resting behaviour in great tits, their sleep might still be impaired by the anthropogenic disturbances. To elucidate this issue, further studies are necessary that, for instance, measure brain activity.

Title Colour remote sensing of the impact of artificial light at night (I): The potential of the International Space Station and other DSLR-based platforms Type Journal Article
Year 2019 Publication Remote Sensing of Environment Abbreviated Journal Remote Sensing of Environment
Volume 224 Issue Pages 92-103
Keywords Remote Sensing; Instrumentation
Abstract Sensors on remote sensing satellites have provided useful tools for evaluation of the environmental impacts of nighttime artificial light pollution. However, due to their panchromatic nature, the data available from these sensors (VIIRS/DNB and DMSP/OLS) has a limited capacity accurately to assess this impact. Moreover, in some cases, recorded variations can be misleading. Until new satellite platforms and sensors are available, only nighttime images taken with DSLR cameras from the International Space Station (ISS), airplanes, balloons or other such platforms can provide the required information. Here we describe a theoretical approach using colour-colour diagrams to analyse images taken by astronauts on the ISS to estimate spatial and temporal variation in the spectrum of artificial lighting emissions. We then evaluate how this information can be used to determine effects on some key environmental indices: photopic vision, the Melatonin Suppression Index, the Star Light Index, the Induced Photosynthesis Index, production of NO2-NO radicals, energy efficiency and CO2 emissions, and Correlated Colour Temperature. Finally, we use the city of Milan as a worked example of the approach.

Title New nighttime roadway lighting documentation applied to public safety at night: A case study in San Antonio, Texas Type Journal Article
Year 2019 Publication Sustainable Cities and Society Abbreviated Journal Sustainable Cities and Society
Volume 46 Issue Pages 101459
Keywords Lighting; Public Safety; Security; Planning
Abstract Built environment and public safety professionals view street lighting as an important factor in improving the well-being of the community at night. Extant research that has examined the relationship between street lighting and public safety has found inconclusive or mixed results and has called for more extensive lighting metrics. Using new lighting measurement technologies and geographic information science, this study builds on previous work to demonstrate new metrics to consider when evaluating public safety, specifically crime and traffic accidents. Downtown San Antonio, Texas is used as a case study to explore illuminance levels on roadways and the driver’s eye, and how these metrics can be used to understand the lighting characteristics of where crime and traffic accidents occur. The findings indicate that the central downtown district in San Antonio has higher illuminance levels than the existing roadway lighting guidelines while the residential downtown neighborhoods have insufficient light levels. Statistical analysis reveals that roadway illuminance levels are higher in areas where no crime occurred and driver’s eye illuminance levels are lower in areas with no traffic accidents. The findings prove the usefulness of new lighting documentation techniques and support the importance of considering illuminance metrics when assessing crime and traffic accidents at night.

Title Study on the emergy-based thermodynamic geography of the Jing-Jin-Ji region: Combined multivariate statistical data with DMSP-OLS nighttime lights data Type Journal Article
Year 2019 Publication Ecological Modelling Abbreviated Journal Ecological Modelling
Volume 397 Issue Pages 1-15
Keywords Remote Sensing
Abstract Emergy analysis is one of the ecological thermodynamics methods. With a specific set of indicators, it is proved to be highly informative for sustainability assessment of national/regional economies. However, a large amount of data needed for its calculation are from official statistical data by administrative divisions. The spatialization of emergy in early researches were limited to the administrative boundaries. The emergy inside an administrative boundary renders a single value, which hides plenty of information for more precise regional planning.

This study develops a new methodology for mapping the spatial distribution of emergy density of a region. The renewable resource distribution can be mapped based on latest geospatial datasets and GIS technology, instead of solely relying on statistics and yearbooks data. Besides, a new spatialization method of non-renewable emergy based on DMSP-OLS nighttime lights data is proposed. Combined with the radiation calibration data, the problem of light saturation of DMSP-OLS nighttime lights data was solved to improve the emergy spatial detail of city centers. With a case study of Jing-Jin-Ji region, results showed that this method could generate a high-resolution map of emergy use, and depict human disturbance to the environment in a more precise manner. This may provide supportive information for more precise land use planning, strategic layout and policy regulation, and is helpful for regional sustainable development.

Title The lighting transition in rural Africa — From kerosene to battery-powered LED and the emerging disposal problem Type Journal Article
Year 2017 Publication Energy for Sustainable Development Abbreviated Journal Energy for Sustainable Development
Volume 39 Issue Pages 13-20
Keywords Lighting; Energy
Abstract People without electricity access, numbering today more than 500 million in rural Africa alone, have been using dim and sooty kerosene lamps and candles for their lighting purposes for decades. In the present paper, current lighting usage patterns are systematically assessed using detailed new survey data from seven countries across Sub-Saharan Africa. The data makes evident that a transition has taken place in recent years, both unnoticed by and without external support from governmental or non-governmental organizations: the rural population without electricity in Africa has replaced kerosene lights and candles by simple, yet more efficient and cleaner LED lamps powered by non-rechargeable batteries. Nevertheless, we also show that the discharged batteries are generally disposed of inappropriately in latrines or the nature. The toxic content of many dry-cell batteries and their accumulation at local litter hotspots may have harmful repercussions on health and the environment. We conclude by suggesting that rapid action is needed to, first, install an effective monitoring system on batteries that enter the continent and, second, put in place an appropriate waste management system.
