Special Issue Information

Dear Colleagues,

In the current Anthropocene era, humans have exerted unproportional impacts on the natural environment. They have caused significant environmental deterioration, resulting in threats to ecosystem functioning and further deterioration of the sustainability of human society. Worldwide, urban agglomerations have expanded rapidly since the Industrial Revolution era. Currently, cities accommodate more than 50% of the global population, but their intense activities increase the frequency of extreme events (e.g., droughts, rainstorms, and floods) and human-induced environmental degradation (e.g., biodiversity loss, water security, atmospheric pollution, the urban heat island effect, and land subsidence). Over the past decades, newly emerging techniques and methods of remote sensing, particularly optical, thermal, and microwave remote sensing approaches, have deepened our understanding of the urban–nature relationship through the facets of human-induced environmental deterioration, which can be monitored and quantitatively evaluated using multiple-source and long time series remote sensing datasets.  Although we have witnessed this boom in technology and theories of remote sensing science that facilitate the studies of the combined influences of global climate change and urbanization, it should be noted that remote sensing approaches can only provide the apparent physical evidence of the urban–nature relationship, e.g., evapotranspiration, land surface temperature, heat flux, and atmospheric CO2 concentration. In other words, an insightful analysis for interpreting the cause–effect mechanism of the urban–nature relationship requires collaborative research integrating remote sensing and related sciences. Thus, to better address the nexus between intensive human activities and their associated environmental impacts, a transdisciplinary approach that combines the knowledge of remote sensing, spatial analysis, numeric simulations, and other related domains is critical to better understand the causes and possible risks of climate change and urbanization.

This Special Issue aims to provide an opportunity to exchange ideas among scholars, planners, and decision makers who are engaged in climate change, urban resilience, land development, disaster reduction and prevention, natural resource management, ecosystem restoration, and related domains. Thus, in the sense of a transdisciplinary approach, innovative manuscripts that apply state-of-the-art theories and methods using remote sensing, spatial analysis, process-based modeling, and quantitative statistics to address the topic of this Special Issue are expected.

Original articles and review papers including, but not limited to, the following themes are welcome:

  • Weather extremes;
  • Urban resilience;
  • Climate change, mitigation, and adaptation;
  • Multi-source remote sensing data;
  • Land development pattern;
  • Artificial modification of climate;
  • Urban heat island effect;
  • Urban geological risk;

Water bodies can offer local microclimates that have the potential to attenuate the effects of urban heat islands by reducing local temperature. This capability is shaded when the river is channelized. In such cases, the river temperature rises during hot periods, leading to negative impacts on the water quality. The main aim of this paper is to develop a local simple model to predict the temperature of the Dâmbovița River at its exit from Bucharest City, the capital of Romania. The location is chosen based on the historical critical impacts, in terms of extreme heatwaves that took place during hot summers, as well as future possible risks due to climate change. The water temperature prediction model is based on an artificial neural network that uses the Levenberg–Marquardt algorithm, due to its stability and rapid convergence capabilities. The model forecasts, with an accuracy of ±1 °C, the water temperature in an ungauged, downstream location, as a function of measured air and upstream water temperatures. The proposed model represents a first attempt to provide water managers in Bucharest City with a useful tool that will allow them to take timely measures to counteract the unwanted effects that can be generated by high water temperatures.

The urban underlying surface may affect the thunderstorm process. However, current research on this phenomenon is still in its infancy. This paper aimed to analyze the influence of the urban underlying surface on the evolution of thunderstorm organization through ground observation and numerical simulation. The results indicated that when the thunderstorm system with strong synoptic conditions passed through the built-up area of Beijing, it exhibited obvious bifurcation and detour. The dynamic field of near-surface cold pools could serve as diagnostic indicators for understanding how the urban underlying surface affects the thunderstorm process. The large-scale compact-rise clusters in the city center could alter the movement direction and path of the cold pool outflow, thereby influencing the thunderstorm organization process. In addition to the spatial configuration of the building complex, the city size might also be an important factor influencing the thunderstorm process. This study might provide a fundamental foundation and technical support for predicting and assessing urban thunderstorm disasters. Full article
