Title Characterizing the zenithal night sky brightness in large territories: how many samples per square kilometre are needed? Type Journal Article
Year 2017 Publication Monthly Notices of the Royal Astronomical Society Abbreviated Journal (up)
Volume 473 Issue 3 Pages 4164-4173
Keywords Instrumentation; atmospheric effects; light pollution; numerical methods; photometry
Abstract A recurring question arises when trying to characterize, by means of measurements or theoretical calculations, the zenithal night sky brightness throughout a large territory: how many samples per square kilometre are needed? The optimum sampling distance should allow reconstructing, with sufficient accuracy, the continuous zenithal brightness map across the whole region, whilst at the same time avoiding unnecessary and redundant oversampling. This paper attempts to provide some tentative answers to this issue, using two complementary tools: the luminance structure function and the Nyquist–Shannon spatial sampling theorem. The analysis of several regions of the world, based on the data from the New world atlas of artificial night sky brightness, suggests that, as a rule of thumb, about one measurement per square kilometre could be sufficient for determining the zenithal night sky brightness of artificial origin at any point in a region to within ±0.1 magV arcsec–2 (in the root-mean-square sense) of its true value in the Johnson–Cousins V band. The exact reconstruction of the zenithal night sky brightness maps from samples taken at the Nyquist rate seems to be considerably more demanding.

Title Insights into the impacts of three current environmental problems on Amphibians Type Journal Article
Year 2018 Publication European Journal of Ecology Abbreviated Journal (up)
Volume 4 Issue 2 Pages 15-27
Keywords Animals; Review
Abstract Global warming, light pollution and noise are common human-induced environmental problems that are escalating at a high rate. Their consequences on wildlife have mostly been overlooked, with the exception of a few species with respect to climate change. The problems often occur simultaneously and exert their negative effects together at the same time. In other words, their impacts are combined. Studies have never focused on more than one problem, and so, such combined effects have never been understood properly. The review addresses this lacuna in the case of amphibians, which are a highly vulnerable group. It divides the overall impacts of the problems into seven categories (behaviour, health, movement, distribution, phenology, development and reproductive success) and then assesses their combined impact through statistical analyses. It revealed that amphibian calling is the most vulnerable aspect to the combined impacts. This could provide important input for conservation of amphibians.

Title Night Lights, Economic Growth, and Spatial Inequality of Thailand Type Journal Article
Year 2016 Publication PIER Discussion Papers Abbreviated Journal (up)
Volume 26 Issue Pages
Keywords Remote Sensing
Abstract This paper explains the method using a set of night light imaginary to estimate GPP of Thailand. This method is quite new but widely acceptable in the area of economics because luminosity of night lights is normally based on the amount of economic activities in each area. The results showed a high and significant correlation betweein the night lights and the GPP growth. Even if the estimation was controlled by some specific factors, such as population density, timing size of agricultural or manufacturing sector, the relationship is still robust. After this relationship is confirmed in the provincial level of Thailand, this research applied the results to show the relationship between economic values and spatial inequality, which indicates new understanding about spatial development patterns.

Title Light Pollution in the Galician Atlantic Islands Maritime-Terrestrial National Park 2018 Report Type Report
Year 2018 Publication Abbreviated Journal (up)
Volume Issue Pages
Keywords Conservation; Spain; Galicia; Europe; national park
Abstract The Galician Atlantic Islands Maritime-Terrestrial National Park (PNMTIAG), with the exception of the island of Cortegada, still has night skies of acceptable quality. However, the PNMTIAG islands are under strong photic pressures, both internal and external, that hinder the preservation of the basic features of the natural night, and call for an immediate action of all concerned stakeholders

Title Contentious Light: An Analytical Framework for Lighting Conflicts Type Journal Article
Year 2018 Publication International Journal of Sustainable Lighting Abbreviated Journal (up)
Volume 20 Issue 1 Pages 62-77
Keywords Society; Lighting; Planning
Abstract This paper takes into view the broad range of contemporary conflicts regarding outdoor lighting. It proposes a working-definition that allows for differentiating lighting conflicts from other forms of lighting-related contention, as well as an analytical framework that allows for the structured description of individual lighting conflicts, and the comparative analysis of multiple cases. The analytical framework was developed based on the social-scientific analysis of media reports of existing conflict cases in Europe and North America, and informed by existing knowledge from the fields of lighting and conflict studies. A central challenge for developing such a framework is dealing with the high level of contingency and complexity of lighting conflicts. The framework reduces this complexity by focusing its field of vision to those aspects that are directly related to the lighting and its contestation. For each of these aspects, it provides sets of descriptive variables that allow for describing the conflicts’ individuality in a standardized – and thus comparable – way. The framework strictly separates the regarded aspects from their judgment by the conflict parties, making it possible to contrast their views on one and the same lighting situation. A visual template supports the process of analysis. It allows for depicting individual cases in short, and for clearly identifying where perspectives differ. At the multiple-case level, the framework not only opens up possibilities for spatial and temporal comparisons of lighting conflicts and the subsequent development of typologies, but also for harnessing their potential for informing the development of more sustainable planning and policy approaches for artificial lighting.
