  Title Why artificial light at night should be a focus for global change research in the 21st century Type Journal Article
  Year 2018 Publication Global Change Biology Abbreviated Journal (up) Glob Chang Biol  
  Volume 24 Issue 3 Pages 872-882  
  Keywords Commentary; Animals; Plants  
  Abstract The environmental impacts of artificial light at night have been a rapidly growing field of global change science in recent years. Yet, light pollution has not achieved parity with other global change phenomena in the level of concern and interest it receives from the scientific community, government and nongovernmental organizations. This is despite the globally widespread, expanding and changing nature of night-time lighting and the immediacy, severity and phylogenetic breath of its impacts. In this opinion piece, we evidence 10 reasons why artificial light at night should be a focus for global change research in the 21st century. Our reasons extend beyond those concerned principally with the environment, to also include impacts on human health, culture and biodiversity conservation more generally. We conclude that the growing use of night-time lighting will continue to raise numerous ecological, human health and cultural issues, but that opportunities exist to mitigate its impacts by combining novel technologies with sound scientific evidence. The potential gains from appropriate management extend far beyond those for the environment, indeed it may play a key role in transitioning towards a more sustainable society.

  Title Commercial farming within the urban built environment – Taking stock of an evolving field in northern countries Type Journal Article
  Year 2018 Publication Global Food Security Abbreviated Journal (up) Global Food Security  
  Volume 17 Issue Pages 30-37  
  Keywords Planning  
  Abstract Urban horticulture has historically contributed to the supply of fresh produce to urban dwellers and has been gaining popularity over the last years in the Global North, with growing awareness of environmental and health concerns. Over the past few years, commercial farms have been emerging in major northern cities, promoting a trend of environmentally friendly food, grown in highly efficient installations on top of or in buildings. This paper presents a scoping study, including: (i) a review of the scientific literature addressing environmental, economic and social aspects of commercial farming in urban contexts; and (ii) a consultation exercise to inform and validate findings from the review, consisting of semi-structured interviews with a few practitioners in the Netherlands. The main findings are: (1) while the recent proliferation of commercial farms in major cities shows that these new modes of urban agricultural production are gaining momentum, establishing their viability as compared to conventional agricultural practices is a challenge when it comes to scalability, resource efficiency, and cost-effectiveness; (2) as it is still a relatively new field, very few studies have been conducted to quantitatively assess the impacts of commercial farming in urban areas; (3) given the complex environmental, economic and social dimensions of urban agriculture, holistic decision support tools could help integrating them in urban areas.

  Title Ice plant growth and phytochemical concentrations are affected by light quality and intensity of monochromatic light-emitting diodes Type Journal Article
  Year 2018 Publication Horticulture, Environment, and Biotechnology Abbreviated Journal (up) Hortic. Environ. Biotechnol.  
  Volume 59 Issue 4 Pages 529-536  
  Keywords Plants  
  Abstract The ice plant (Mesembryanthemum crystallinum L.), widely known to be an effective cure for diabetes mellitus, is also a functional crop. This study was conducted to examine the effects of light quality and intensity of monochromatic light-emitting diodes (LEDs) on ice plant growth and phytochemical concentrations in a closed-type plant production system. Ice plant seedlings were transplanted into a deep floating technique system with a recycling nutrient solution (EC 4.0 dS m−1, pH 6.5). Fluorescent lamps, as well as monochromatic red (660 nm) and blue (450 nm) LEDs, were used at 120 ± 5 or 150 ± 5 µmol m−2 s−1 PPFD with a photoperiod of 14 h/10 h (light/dark) for 4 weeks. Ice plants showed higher growth under the high light intensity treatment, especially under the red LEDs. Furthermore, the SPAD value and photosynthetic rate were higher under the red LEDs with 150 µmol m−2 s−1 PPFD. The ice plant phytochemical composition, such as antioxidant activity and myo-inositol and pinitol concentrations, were highest under the blue LEDs with 150 µmol m−2 s−1 PPFD. Total phenolic concentration was highest under the blue LEDs with 120 µmol m−2 s−1 PPFD. Despite a slightly different dependence on light intensity, phytochemical concentrations responded positively to the blue LED treatments, as compared to other treatments. In conclusion, this study suggests that red LEDs enhance ice plant biomass, while blue LEDs induce phytochemical

  Title Factors influencing Manx Shearwater grounding on the west coast of Scotland Type Journal Article
  Year 2018 Publication Ibis Abbreviated Journal (up) Ibis  
  Volume 160 Issue 4 Pages 846-854  
  Keywords Animals  
  Abstract Grounding of thousands of newly fledged petrels and shearwaters (family Procellariidae) in built‐up areas due to artificial light is a global problem. Due to their anatomy these grounded birds find it difficult to take off from built‐up areas and many fall victim to predation, cars, dehydration or starvation. This research investigated a combination of several factors that may influence the number of Manx Shearwater Puffinus puffinus groundings in a coastal village of Scotland located close to a nesting site for this species. A model was developed that used meteorological variables and moon cycle to predict the daily quantity of birds that were recovered on the ground. The model, explaining 46.32% of the variance of the data, revealed how new moon and strong onshore winds influence grounding. To a lesser extent, visibility conditions can also have an effect on grounding probabilities. The analysis presented in this study can improve rescue campaigns of not only Manx Shearwaters but also other species attracted to the light pollution by predicting conditions leading to an increase in the number of groundings. It could also inform local authorities when artificial light intensity needs to be reduced.

  Title Smart Outdoor Light Desktop Central Management System Type Journal Article
  Year 2018 Publication IEEE Intelligent Transportation Systems Magazine Abbreviated Journal (up) IEEE Intell. Transport. Syst. Mag.  
  Volume 10 Issue 2 Pages 58-68  
  Keywords Lighting  
  Abstract Light pollution and nature preservation, are new trends in which the European cities are involved as they evolve into Smart Cities. Internet of Things are changing the way that sensors and management control systems are designed and implemented. In this article, our main objective is to present an Outdoor Light Desktop Central Management architecture using current IoT (Internet of Things) and GIS technologies to improve the energy efficiency, user experience and safety feeling at the same time we are going to decrease light pollution of LED lamps. The challenge is to provide a lighting control system to suit each zone, from residential areas and public spaces to industrial parks, and each context. Furthermore, the design of the technological multi-platform able to operate with any kind of electrical device will be useful in the area of outdoor lighting.
