Title How can the urban landscape affect urban vitality at the street block level? A case study of 15 metropolises in China Type Journal Article
Year 2020 Publication Environment and Planning B: Urban Analytics and City Science Abbreviated Journal (up)
Volume Issue Pages
Keywords Remote Sensing
Abstract Urban vitality, as a metric, measures the attractiveness and competitiveness of a city and is a driver of development. As the physical and social space of human activities, the urban landscape has close connections with urban vitality according to classical theories. However, limited quantitative criteria for the urban landscape and gaps between macro urban planning and micro design create difficulties when constructing a vibrant city. In this study, we quantitatively examined the relationship between the urban landscape and urban vitality at the street block level using geospatial open data to discover where, how, and to what extent we could improve urban vitality, taking 15 Chinese metropolises as a case study. Results indicate that, among the three aspects of the urban landscape considered, the city plan pattern has the highest effect on stimulating vitality, followed by the land use and the patterns of building form. Specifically, the three-dimensional form of buildings has a greater effect than a two-dimensional form. In addition, convenient transportation, a compact block form, diverse buildings, mixed land use, and high buildings are the main characteristics of vibrant blocks. The results also show that the effects of the urban landscape have spatial variations and obvious diurnal discrepancies. Furthermore, over 20 and 33% of the blocks in these cities are identified as low-vitality blocks during the day and night, respectively, and are then categorized into six different types. The identification of the common characteristics of these low-vitality blocks can be taken as references for designing a vibrant urbanity.

Title The Effect of Public Expenditure on the Housing Deficit in Peru at the Municipal Level Type Journal Article
Year 2020 Publication Housing Policy Debate Abbreviated Journal (up)
Volume Issue Pages 1-23
Keywords Remote Sensing
Abstract What impact does public expenditure on housing have on the deficit in a municipality? This article answers this question for Peru for the period 2001–2013. Municipalities with high expenditure levels saw a reduction in the number of households lacking access to water, sanitation, and electricity. There was no significant change in cohabitation, overcrowding, or lack of documents of ownership. The analysis was based on the empirical association between mineral exploitation and housing deficit at the municipal level. Municipalities that benefited from the mineral boom after 2007 saw housing expenditures increase dramatically, which reduced the housing deficit associated with poor materials to 18% from 33% (the national average). In addition, the housing deficit related to lack of water, sanitation, and electricity decreased from 26% to 22%.

Title Analysis of the Status of Light Pollution and its Potential Effect on Ecosystem of the Deogyusan National Park Type Journal Article
Year 2020 Publication Korean Journal of Environment and Ecology Abbreviated Journal (up)
Volume 34 Issue 1 Pages 63-71
Keywords Conservation; Ecology; Remote Sensing
Abstract This study characterized the spatial and seasonal patterns of light pollution in the Deogyusan National Park and examined the potential effects of light pollution on ecosystems in the park using light intensities derived from VIIRS (Visible Infrared Imaging Radiometer Suite) DNB (Day and Night Band) nightlight images collected in January and August 2018. Results showed that the Muju Deogyusan resort had the greatest light intensity than other sources of light pollution in the park, and light intensity of the resort was much higher in January than in August, suggesting that artificial lights in ski slopes and facilities were the major source of light pollution in the park. An analysis of an urban-natural light pollution gradient along a neighboring urban area through the inside of the park indicated that light radiated from a light pollution source permeated for up to 1km into the adjacent area and contaminated the edge area of the park. Of the legally protected species whose distributions were reported in literature, four mammals (Martes flavigula, Mustela nivalis, Prionailurus bengalensis, Pteromys volans aluco), two birds (Falco subbuteo, Falco tinnunculus), and nine amphibians and reptiles (Onychodactylus koreanus, Hynobius leechii, Karsenia koreana, Rana dybowskii, Rana huanrenensis, Elaphe dione, Rhabdophis tigrinus, Gloydius ussuriensis, Gloydius saxatilis) inhabited light-polluted areas. Of those species inhabiting light-polluted areas, nocturnal species, such as Prionailurus bengalensis and Pteromys volans aluco, in particular, were vulnerable to light pollution. These results implied that protecting ecosystems from light pollution in national parks requires managing nighttime light in the parks and surrounding areas and making a plan to manage nighttime light pollution by taking into account ecological characteristics of wild animals in the parks.

Title Making Darkness a Place-Based Resource: How the Fight against Light Pollution Reconfigures Rural Areas in France Type Journal Article
Year 2020 Publication Annals of the American Association of Geographers Abbreviated Journal (up)
Volume Issue Pages
Keywords Conservation; Society
Abstract Light pollution refers to the degradation of darkness through the use of artificial light at night in and around human infrastructures. This pollution is intrinsically related to urbanization and spills out from urban areas to affect both rural and protected areas. Several countries are organizing the fight against light pollution. There, local communities are experimenting with environmental policies designed to protect darkness. The challenge is about preserving biodiversity and fostering the energy transition. In France, a number of pioneering rural areas are experimenting with mechanisms that include this dual implication. Two of them provide the case study for this article. We show how these areas turn darkness into a specific resource. We identify three specification processes. The first obeys an anthropocentric utilitarian rationale and is part of the “economicization” of the environment in the line of shallow ecology. The second follows a rationale of ecocentric conservation and is part of the radical ecologization of the economy, in line with deep ecology. The third is in keeping with an integrated socioecosystemic rationale enshrining the interdependence between development, planning, the preservation of biodiversity, and energy savings. Local areas are plagued with specification controversies. These areas become incubation rooms; that is, spaces for resolving these controversies. These are reflected in a transition operator enabling the local area to take a fresh trajectory in terms of development and planning.

Title Lighting for Heritage Building: A Case Study of the Lighting Design Applied on St. George’s Church in George Town, Penang Island Type Journal Article
Year 2020 Publication Awang M., Meor M Fared M. (eds) ICACE 2019. Lecture Notes in Civil Engineering Abbreviated Journal (up)
Volume 59 Issue Pages 113-119
Keywords Lighting
Abstract Light is one of the critical aspects of architecture, yet it is one of the understated elements in our daily lives. Light has a significant spot to form events, activities, and memories. Scientific studies have shown that appropriate and proper lighting does not only affect human health but daily human moods as well. Nowadays, lighting fixtures play essential roles in architecture and markets. A proper lighting fixture helps to highlight the structure, textures, and form of the shape of a building. However, the designers tend to focus more on the art aesthetics rather than the conservation ethics, such as the colorful design and the attractive lighting fixtures on the building, while the prime concern should be on realizing the impact of the lighting fixture toward the environment. The objectives of this study are to highlight the issues of the lighting system of the heritage building and suggest some recommendations to meet the requirements for the heritage building for better lighting design. The data for this research was collected using the quantitative method. Thus, as a result, it is found out that lighting design highlights the historical building, and therefore, attracts tourists, which benefit the economy. However, improper lighting installation leads to a negative impact on the society and human health.
