New Frontiers in Flood Risk Management

Flood risk management has been studied extensively and intensively in many academic fields from civil engineering, sociology, economics, culture, and even psychology. However, the fact that flooding accounts for a greater number of damaging events than any other type of natural events worldwide on an yearly scale proves that our understanding of flooding is still insufficient, flawed, and fragmented. This chapter intends to shed new light on a number of issues that deserve more comprehensive study in order to advance flood risk management. As a result, a new two-layer framework of vulnerability is proposed, which can lead to a better understanding of, and new approaches to, flood risk management

(Special issue on Environment Management and Spatial Planning)

This special issue is a collection of papers presented in the 2017 Workshop on Urban Planning and Management held in Tokyo, Feb. 18-19, 2017. The selected papers are published with IRSPSD International, which can be grouped around two pillars. Namely, Water dimension and Energy dimension in urban studies

Move from Resilience Conceptualization to Resilience Enhancement

This chapter provides an analysis of various resilience definitions and depicts the differences in definition between engineering, ecological and socio-ecological resilience in an easy-to-understand graphic representation. It also articulates commons and differences between conventional flood risk management and resilience-based flood management and presents a mathematical formulation to facilitate resilience discussion. Furthermore, it highlights some studies and initiatives towards the operationalization of the resilience concept in flood disaster management practice. The most important message this chapter is intended to deliver is that resilience is not just about bouncing back. Indeed, it should be enhanced to bounce forward

Proceedings of International Virtual Conference 2020 on Spatial Planning and Sustainable Development: Lockdown Urbanism

The ongoing pandemic has led to more than 100 million of confirmed cases and 2.16 million deaths of people globally (up to late January 2021). A variety of health and well-being issues resulting from the largest scale lockdown in the 21st century have addressed emerging global challenges for urban sustainability and smart city development: how to creatively design local neighbourhood and home in response to changing lifestyles? How to smartly design digital and social infrastructure to support individual adaption to changed life-styles? How urban governance and smart city deal with a variety of social, spatial and information inequalities? The multi-disciplinary and international discussion and debates on these timely questions help rethink the planning and governance of healthy city in the uncertain contexts

Research on Power Grid Resilience and Power Supply Restoration during Disasters-A Review

Electric power system plays an indispensable role in modern society, which supplies the energy to residential, commercial, and industrial consumers. However, the high-impact and low-probability natural disasters (i.e., windstorm, typhoon, and flood) come more frequent because of the climate change in the recent years, which may sequentially cause devastating damages to the infrastructure of power systems. The aim of this paper is mainly to explore and review the resilience of power grid system during the disaster and the power supply management strategies to recover the power grid. Firstly, the category of natural disasters and different influences on power grid are discussed. Then, the definition of power grid resilience is explored and the supply management strategies copying with disasters are introduced, such as microgrids and distributed generation systems. Specially, the electric vehicles (EVs) equipped with large-capacity battery pack in the transportation network can also be considered as the distributed power sources with mobility. Thus, the conceptual frameworks of integrating large-scale EVs into the power grid to fasten restoration of the power systems in the pre-disaster/post-disaster are emphatically investigated in this paper. Finally, the opportunities and challenges in further research on employing EVs for emergency power supply in the extreme weather events are also discussed

The novel method for LAI inversion using Lidar and hyperspectral data

For inversion of Leaf area index (LAI) in large scale, it is of great significance to integrate space-borne Lidar and optical remote sensing data effectively. In order to improve the estimation precision of leaf area index, an analyzing method based on Lidar and hyperspectral data was proposed. Through the processing of Lidar (Light Identification Detection and Ranging) and hyperspectral data, the LAI estimation model was established based on statistic analysis method in the study area. The results showed that the Lidar and hyperspectral data joint inversion model which considers the optical remote sensing of biophysical parameters can provide good estimates of LAI inversion, shows high accuracy (R2=0.8948, RMSE=0.2120),which reveals the great potential to enhance the accuracy of LAI estimation by using Lidar and hyperspectral data
