Title Contrasting trends in light pollution across Europe based on satellite observed night time lights Type Journal Article
Year 2014 Publication Scientific Reports Abbreviated Journal Sci Rep
Volume 4 Issue Pages 3789
Keywords remote sensing; light pollution; light at night; DMSP-OLS; satellite; light pollution reduction
Abstract Since the 1970s nighttime satellite images of the Earth from space have provided a striking illustration of the extent of artificial light. Meanwhile, growing awareness of adverse impacts of artificial light at night on scientific astronomy, human health, ecological processes and aesthetic enjoyment of the night sky has led to recognition of light pollution as a significant global environmental issue. Links between economic activity, population growth and artificial light are well documented in rapidly developing regions. Applying a novel method to analysis of satellite images of European nighttime lights over 15 years, we show that while the continental trend is towards increasing brightness, some economically developed regions show more complex patterns with large areas decreasing in observed brightness over this period. This highlights that opportunities exist to constrain and even reduce the environmental impact of artificial light pollution while delivering cost and energy-saving benefits.

Title Repeatable and standardised monitoring of threats to Key Biodiversity Areas in Africa using Google Earth Engine Type Journal Article
Year 2020 Publication Ecological Indicators Abbreviated Journal Ecological Indicators
Volume 109 Issue Pages 105763
Keywords Remote Sensing
Abstract Key Biodiversity Areas (KBAs) are sites that make significant contributions to the global persistence of biodiversity, but identification of sites alone is not sufficient to ensure their conservation. Monitoring is essential if pressures on these sites are to be identified, priorities set and appropriate responses developed. Here, we describe how analysis of freely available data on a cloud-processing platform (Google Earth Engine) can be used to assess changes in three example remotely sensed threat indicators (fire frequency, tree loss and night-time lights) over time on KBAs in Africa. We develop easily repeatable methods with shared code that could be applied across any geographic area and could be adapted and applied to other datasets as they become available. Fire frequency was found to have increased significantly on 12.4% of KBAs and 15.9% of ecoregions, whilst rates of forest loss increased significantly on 24.3% of KBAs and 22.6% of ecoregions. There was also evidence of significant increases in night-time lights on over half (53.3%) of KBAs and 39.6% of ecoregions between 1992 and 2013, and on 11.6% of KBAs and 53.0% of ecoregions between 2014 and 2018.

Title Exploring the Spatial Economy by Night Type Report
Year 2016 Publication n/a Abbreviated Journal n/a
Volume n/a Issue n/a Pages n/a
Keywords Economics; DMSP; DMSP-OLS; remote sensing; spatial distribution
Abstract Night satellite images may offer an interesting tool to generate socio-economically relevant data and to analyse the evolution of space, e.g. cities or rural areas, and how spatial units interact over time. This paper is just an essay with preliminary ideas for discussion; the approach is explorative-methodological rather than one putting an empirical focus on a defined research item. Empirics discussed in this paper are just various examples collected from tinkering.

The DMSP-OLS images and adequate image analysis software such as ImageJ (in some cases to be complemented by further statistics software) provide a useful perspective for the analysis of spatial change. Since there is a stable and significant correlation between social and economic variables (population density, GDP PPP) and luminosity, such image analyses contain important information on spatial economic development. Analysis of night imagery is certainly not adequate to replace the statistical analysis of regional data, but it is a good tool to confirm and illustrate patterns of spatial heterogeneity and spatial dependence over time.

Title What do night satellite images and small-scale grid data tell us about functional changes in the rural-urban environment and the economy? Case studies Frankfurt-Rhein/Main and Ljubljana Urban Region Type Journal Article
Year 2018 Publication Abbreviated Journal
Volume Issue Pages
Keywords Remote Sensing
Abstract This study addresses how nocturnal satellite imagery can be used in spatial analysis of rural-urban relations. It shows how a novel approach can be used to complement the prevalent traditional survey methods below the data resolution level of official regional statistics. The overarching aim is to contribute with a novel database and different empirical tools to broaden spatial information for decision-making in policy and planning at small spatial scale amongst municipalities. The accuracy of spatial information is expected to be substantially enhanced, paving ways for better rural-urban planning coordination and synergies.
