Title Unawareness in environmental protection: The case of light pollution from traffic Type Journal Article
Year 2012 Publication Land Use Policy Abbreviated Journal Land Use Policy
Volume 29 Issue 3 Pages 598-604
Keywords Public Safety; public policy; traffic safety
Abstract New information is often emphasized as a basis of effective and scientifically sound environmental policy and management. However, outdated or incorrect information is not automatically nor instantly replaced by new insights. This article focuses on the various ways environmental information can be unintentionally left with insufficient attention or purposefully neglected. Energy-related emissions caused by road traffic in Finland are used as an illustrative example and light pollution caused by artificial lighting is identified as an emerging issue that has gained especially low recognition in the environmental agenda. Four different reasons for this lack of recognition are discussed: recognized unawareness, false awareness, deliberate unawareness and concealed awareness. Paying attention to light pollution is important because of various ecological, socio-cultural and economic effects but also because implementing measures aimed for reducing light pollution create possibilities for alleviating other social and environmental problems in transport and land use policies.

Title Energy and urban form. The growth of European cities on the basis of night-time brightness Type Journal Article
Year 2017 Publication Land Use Policy Abbreviated Journal Land Use Policy
Volume 61 Issue Pages 103-112
Keywords Remote Sensing
Abstract The European urban system has experienced significant transformations over the last two decades, affecting both the system’s articulation and hierarchy, and the morphology of urban areas. The sources of information on land use, although increasingly precise and exhaustive, present some limitations when it comes to identifying and quantifying this development, particularly due to their sporadic nature. In this context, the advances in the availability, precision, territorial coverage and recurrence of night-time satellite images offer new opportunities to assess the transformation of land uses. Under the assumption that there is a direct relationship between light emissions and the level of urbanisation, the present study identifies the development of the European urban system between 1992 and 2012. In this respect, the level of brightness suggests that the extension of urban land uses has been much greater than those calculated by using other sources, such as aerial photography or planning regulations. The contrast with these sources demonstrates that, even though night-time images are subject to significant limitations, their use can have advantages in the explanation of new patterns of land use. Thus, brightness could contribute to a more complex picture of the urbanization process, measuring not only the artificialisation of land but also the spread and intensity of urban uses of space.
