Title (up) A Bright Idea for Measuring Economic Growth Type Journal Article
Year 2011 Publication The American Economic Review Abbreviated Journal Am Econ Rev
Volume 101 Issue 3 Pages 194-199
Keywords Remote Sensing
Abstract The quantity of human-generated light visible from outer space reflects variation in both population density and income per capita. In this paper we explore the usefulness of the change in visible light as a measure of GDP growth. We discuss the data, and then present a statistical framework that uses lights growth to augment existing income growth measures, assuming that measurement errors in the two series are uncorrelated. For some countries with very poor income measurement, we significantly revise estimates of growth. Our technique also produces growth estimates for cities or regions where no other data are available.

Title (up) A carbon footprint and energy consumption assessment methodology for UHI-affected lighting systems in built areas Type Journal Article
Year 2016 Publication Energy and Buildings Abbreviated Journal Energy and Buildings
Volume 114 Issue Pages 96-103
Keywords Remote Sensing; Energy
Abstract This paper investigates the effects of urban heat island (UHI) on outdoor lighting systems in terms of GHG emissions: a novel methodology is proposed to assess the carbon footprint (CF) change of lighting services in built areas caused by UHI-induced ΔT with particular focus on the evaluation of the energy consumption. The methodology can be applied also to other activities affected by the UHI, such as HVAC and transport systems. In particular, ΔCF was introduced by a two-fold approach: the quantification of the CF change due to UHI (as difference between CF in an UHI-affected case and CF for an UHI-less case) and the CF change produced by a 1 °C temperature change. A focus on LED lamps was developed: the lifetime of LEDs exponentially decreases with increasing temperature and the luminous flux exponentially decays with operation time. UHI (i.e. the increase in ambient temperature) affects the lifetime and the luminous flux of lamps producing higher energy consumption and higher replacement rates. Results showed that a positive ΔT due to UHI produces a positive ΔCF, which also becomes economically relevant in long-term scenarios. A case study was analyzed by applying the proposed methodology to Rome outdoor public lighting.

Title (up) A Comparative Study on Current Outdoor Lighting Policies in China and Korea: A Step toward a Sustainable Nighttime Environment Type Journal Article
Year 2019 Publication Sustainability Abbreviated Journal Sustainability
Volume 11 Issue 14 Pages 3989
Keywords Lighting; Policy
Abstract Light pollution is a serious environmental issue with many adverse effects on human health and the ecosystem as a whole. Accordingly, many countries have issued laws and regulations to limit the effects of artificial lighting at night (ALAN). The Republic of Korea and China are among the few countries that have drafted laws to curb light pollution. In the present study, we gathered data related to light pollution regulations and ordinances in both China and Korea. We then carried out a comparative analysis of the light pollution laws of both countries. We found that, although the two countries share a similar socio-economic background, they have different approaches to the issue of light pollution. The information provided in this study serves as a guideline to countries that wish to develop their own light pollution policies. In addition, the conclusions provided in our study offer potential improvements to local and national light pollution policies in both the Republic of Korea and China.

Title (up) A comparison between emergence and return activity in pipistrelle bats Pipistrellus pipistrellus and P. pygmaeus Type Journal Article
Year 2006 Publication Acta Chiropterologica Abbreviated Journal
Volume 8 Issue 2 Pages 381-390
Keywords animals; fying mammals: animal behaviour
Abstract Bats may be vulnerable to predation during evening emergence and morning return to their roosts. Early emergence increases the risk of exposure to raptorial birds, but emerging late confers a risk of missing the dusk peak of aerial insects. Here, both emergence and return activity was studied in detail at the same roosts for the first time. We investigated six maternity colonies of pipistrelle bats (Pipistrellus pipistrellus and P. pygmaeus) in NE Scotland and recorded light levels and time of emergence and return of the bats with respect to sunset and sunrise on the same nights. Parameters of return activity generally occurred at lower light intensities than those of emergence. Therefore, the interval between dawn return and sunrise was generally longer than that between sunset and dusk emergence. Emergence and return were equal in duration. Bats clustered more on emergence in comparison with return during pregnancy and lactation, whereas during postlactation this trend was reversed.
