Title Seasonal population estimates based on night-time lights Type Journal Article
Year 2018 Publication (up) Computers, Environment and Urban Systems Abbreviated Journal Computers, Environment and Urban Systems
Volume 68 Issue Pages 133-141
Keywords Remote Sensing
Abstract The objective of this paper is to present a method for estimating seasonally specific ambient population counts. The central assumption is that the variation in observed night-lights is a valid proxy for ambient population. Island populations are used for validation, where it is possible to derive estimates of ambient population from national statistics. The method is then applied to the whole of Greece. The validation shows a strong correlation amongst night-lights derived estimates and the reference dataset. Based on the proposed method, national maps are produced showing the month when seasonality is in its peak, the peak value during that month and the overall length of the season, in terms of how many months exceed a certain threshold. Different seasonality patterns are revealed. An advantage of the proposed method, compared to other contemporary approaches, is that it is based on public domain, global data.

Title Estimating population and energy consumption in Brazilian Amazonia using DMSP night-time satellite data Type Journal Article
Year 2005 Publication (up) Computers, Environment and Urban Systems Abbreviated Journal Computers, Environment and Urban Systems
Volume 29 Issue 2 Pages 179-195
Keywords Remote Sensing
Abstract This paper describes a methodology to assess the evidence of human presence and humanactivities in the Brazilian Amazonia region using DMSP/OLS night-time satellite sensorimagery. It consists on exploring the potential of the sensor data for regional studies analysingthe correlation between DMSP night-time light foci and population, and the correlation be-tween DMSP night-time light foci and electrical power consumption. In the mosaic of DMSP/OLS night-time light imagery from September 1999, 248 towns were detected from a total of749municıpiosin Amazonia. It was found that the night-time light foci were related to human presence in the region, including urban settlements, mining, industries, and civil construction,observed in ancillary Landsat TM and JERS imagery data. The analysis considering only thestate of Para revealed a linear relation (R2¼0:79) between urban population from the 1996census data and DMSP night-time light foci. Similarly, electrical power consumption for 1999was linearly correlated with DMSP night-time light foci. Thus the DMSP/OLS imagery can beused as an indicator of human presence in the analysis of spatial–temporal patterns in theAmazonia region. These results are very useful considering the continental dimension ofAmazonia, the absence of demographic information between the official population census(every 10 years), and the dynamics and complexity of human activities in the region. ThereforeDMSP night-time light foci are a valuable data source for global studies, modelling, and planning activities when the human dimension must be considered throughout Amazonia.

Title Designing digital displays and interactive media in today’s cities by night. Do we know enough about attracting attention to do so? Type Journal Article
Year 2018 Publication (up) Conscious Cities Anthology Abbreviated Journal
Volume Issue Pages
Keywords Commentary; Lighting
Abstract With the huge transformation in the development of digital screen technology and its consistently decreasing cost, digital billboards are progressively replacing traditional static, two-dimensional poster advertisements in our cities1. Previously, due to the substantial expenditure involved, they were only available to major international brands with vast promotional resources to build their brand fame. Today, however, they are being used increasingly by advertisers to deliver all kinds of messages from simple ones to more sophisticated, interactive storytelling. Soon, however, even newer ways of purchasing advertisements using computers will be introduced by the outdoor media industry to address the public, so potentially everybody will be able to rent out available advertising space and communicate the message. But are we ready for this next step? As there are no proper guidelines or regulations in place for this new medium in the urban realm, today we are facing issues such as no integration of the display’s location into the built environment, no specifications based on knowledge of human perception and the human centric design approach, no control over its content quality, and so called ‘display blindness’2 seems to be a common collective urban experience at night. Taking London as one of the most cutting-edge outdoor digital advertising environments in the world3 (with the largest number of these screens traditionally located in or in close proximity to Piccadilly Circus) this paper discusses various aspects of this new medium. Besides the layout and geometry of the space, it also focuses on navigation and attracting the visual attention of passers-by at night in a practical human oriented context. Additionally, questions regarding complex sensory, social, special and interactional issues and the necessity for interdisciplinary collaboration have been addressed.

Title Implications for conservation of anthropogenic impacts on visual communication and camouflage Type Journal Article
Year 2016 Publication (up) Conservation Biology : the Journal of the Society for Conservation Biology Abbreviated Journal Conserv Biol
Volume 31 Issue 1 Pages 30-39
Keywords Conservation
Abstract Anthropogenic environmental impacts can disrupt the sensory environment of animals and affect important processes from mate choice to predator avoidance. Currently these effects are best understood for auditory and chemo-sensory modalities and recent reviews highlight their importance for conservation. Here we summarise how anthropogenic changes to the visual environment (ambient light, transmission, backgrounds) affect visual communication and camouflage, and highlight implications for conservation. These implications are particularly evident for disrupted camouflage due to its tight links with survival while the conservation importance of impaired visual communication is less well-documented. Such effects can be potentially severe when they affect critical processes such as pollination or species recognition. However, when impaired mate choice does not lead to hybridization, the conservation consequences are less clear. We suggest that the demographic effects of human impacts on visual communication and camouflage will be particularly strong when: (a) human-induced modifications to the visual environment are evolutionary novel, that is, very different from natural variation, (b) affected species and populations have low levels of intraspecific (genotypic and phenotypic) variation and low levels of behavioural, sensory or physiological plasticity and (c) the processes affected are directly related to survival (camouflage), species recognition, or number of offspring produced, rather than offspring quality or attractiveness. The evidence summarized here suggests that anthropogenic effects on the visual environment might be of similar conservation concerns as those on other sensory modalities.

Title A global review of seabird mortality caused by land-based artificial lights Type Journal Article
Year 2017 Publication (up) Conservation Biology : the Journal of the Society for Conservation Biology Abbreviated Journal Conserv Biol
Volume 31 Issue 5 Pages 986-1001
Keywords Animals; Ecology
Abstract Artificial lights at night cause high mortality of seabirds, one of the most endangered groups of birds globally. Fledglings of burrow-nesting seabirds, and to a lesser extent adults, are grounded by lights when they fly at night. We review the current state of knowledge of light attraction, identify information gaps and propose measures to address the problem. Although other avian families such as Alcidae and Anatidae can be involved, the most affected seabirds are petrels and shearwaters: at least 56 species, more than one-third of them (24) threatened, are grounded by lights. Grounded seabirds have been found worldwide, mainly on oceanic islands but also at some continental locations. Petrel breeding grounds confined to formerly uninhabited islands are particularly at risk from ever-growing levels of light pollution due to tourism and urban sprawl. Where it is impractical to ban external lights, rescue programs of grounded birds offer the most immediate and extended mitigation measures to reduce light-induced mortality, saving thousands of birds every year. These programs also provide useful information for seabird management. However, the data typically are fragmentary and often strongly biased so the phenomenon is poorly understood, leading to inaccurate impact estimates. We identified as the most urgent priority actions: 1) estimation of mortality and impact on populations; 2) assessment of threshold light levels and safe distances from light sources; 3) documenting the fate of rescued birds; 4) improvement of rescue campaigns, particularly in terms of increasing recovery rates and level of care; and 5) research on seabird-friendly lights to reduce attraction. More research is necessary to improve our understanding of this human-wildlife conflict and to design effective management and mitigation measures. This article is protected by copyright.
