Special Issue Information

Dear Colleagues,

Cities are the physical manifestations of major physical and social forces. Those forces interact to change the urban environment and consequently affect the well-being of the people living in cities. In the era of rapid global warming and urbanization, various kinds of environmental problems in cities are getting more severe, engendering significant health impacts on urban dwellers. There is a need for scientific communities to determine the severity and the causes of these environmental problems in urban settings in order to solve the problems, contributing to urban sustainability in the long term. We invite researchers to contribute articles dealing with the various environmental impacts brought by climate change and urban development in cities.

This Special Issue will serve as an interdisciplinary platform for urban study. Scholars from various disciplines may use methods ranging from field research, questionnaire surveys, statistics, remote sensing, geographical information systems, computer modeling, and so on to systematically analyze the effects of climate change and urban development on the physical environments in cities.

This Special Issue will publish original research articles and review articles that help to identify possible future research directions. Topics of interest include, but are not limited to, the following:

  • How and to what extent urban environments are affected by climate change or human activities;
  • The use of big and open data in investigating urban environmental problems;
  • In-depth case studies illustrating the environmental problems in cities;
  • Urban planning in response to environmental problems;
  • Methodological advancement in tracking and tracing urban environmental problems.

This paper proposes a geo-hazard risk assessment technique to analyze the impacts of surface subsidence monitored in a major coal mine in Nigeria. In many developing countries, disaster risk management schemes have mainly focused on traditional singular hazard assessment, vulnerability assessment, or risk assessment. However, it is difficult to use a singular application to adequately address hazard assessment due to the variation in data requirements, factors associated with the hazards, and the various elements at risk. Most times, hazard assessment schemes heavily rely on data and techniques from different global organizations that collate data on disasters, using various scales and objectives to make informed decisions. Several challenges seemingly arise from total reliance on these kinds of data due to standardization, the exact number of potential victims, and the purpose of the data collection. This makes disaster information collected at the local level unique and assessment schemes more complete; however, the coverage is limited worldwide. The proposed approach combines the spatial relationship between vulnerability assessment and elements at risk to highlight the grave consequences of potential disasters. Thus, the aim is to underscore the importance of integrating local-level inputs in analyzing risk factors and vulnerability indicators for hazard assessment. This study was conducted at the Onyeama coal mine in South East Nigeria. This area has experienced severe negative impacts of subsidence over the years. We exploit data from Sentinel-1 Synthetic Aperture Radar (SAR) Satellites and Small-Baseline Subset Differential Interferometric Synthetic Aperture Radar (SBAS-DInSAR) technique to map the study area. The results generate an elements-at-risk database with a particular focus on population density, road networks, and building networks identified as indices for loss estimation. Full article
