Abstract: The travel restriction leads to the enormous economic loss to the tourism industry. In this paper, the economic loss and the environmental gains (e.g., water and energy resources) from COVID-19 impact on China’s tourism industry are estimated based on environmentally extended multiple regional input-output model. Results indicate that the China’s tourism consumption loss triggered 921 billion US$ output loss via supply chain in 2020, which account for 7 % of GDP in 2019. Additionally, the economic loss further ripples tourism water footprint conservation of 10 billion m3 (equal to the annual water consumption of Poland) and tourism energy footprint conservation of 116 million tce (equal to the annual energy consumption of Australia). Findings reveal that regions with large tourism economic losses are not completely consistent with the regions with significant relief of water and energy pressures. Water pressure in Xinjiang (Northwest) and energy pressure in Hainan (South) have been alleviated due to reduced tourism consumption along the Southeast coast. These knock-on effects highlight a deeper internal link between the economy and the environment. The development of tourism in the post-COVID-19 era needs to reduce the direct water and energy footprint of local area by applying advanced water-saving and energy-saving technologies.

Abstract: The mechanism of internal erosion in porous media involves the microstructural evolutions induced by washing out of fine particles under different loading and seepage flow actions. Consequently, the effective stress on the solid skeleton is governed by the transition in velocity and stress of fine particles due to their detachment from the skeleton and then transport through pore channels, in addition to pore pressure. This study is to develop a formulation of work input to account for the interactions and mass exchanges between solid and fluid phases. Coupled mechanical-hydraulic erosion processes can be properly reflected through mass, momentum and energy balances based on Biot’s mixture theory of a three-phase model. This leads to three separate stress-like variables, effective stress, erosion force and hydraulic gradient, in conjugation with three strain-like variables, strain, mass loss and seepage velocity, respectively. The effective stress tensor, different from the classical form by Terzaghi due to the effect of erosion, and coupled hydro-mechanical-erosion criteria are naturally derived from the proposed work input. They consider grain scale mechanisms describing the transition of erodible particles from the solid skeleton to the fluidized state. Systematic formulations and discussions are presented to highlight the promising features of our approach.2023-01-01T00:00:00ZWillingness to Pay for Sponge City Developments: A Perceived Value PerspectiveWang, Y.Liu, X.Zuo, J.Huang, M.https://hdl.handle.net/2440/1399392023-11-27T01:39:35Z2019-01-01T00:00:00ZTitle: Willingness to Pay for Sponge City Developments: A Perceived Value Perspective

Author: Hawken, S.
Abstract: The Drying Green is a radical new urban wetland and park in Gadigal Country, Green Square, Sydney. The park presents a fascinating abstraction of the original wetland systems that characterized the south Sydney landscape more than 200 years ago. The digitally inspired design of the park fuses folded origami-like geometries with smart technologies and natural systems. Designed by landscape architect McGregor Coxall with architect Chrofi and built by Regal Innovations for the City of Sydney, this new landscape celebrates the intensely urban culture of Green Square town centre, which will eventually have a population of over 6,000 residents and 6,000 workers, with densities rivalling parts of Hong Kong or Tokyo.2023-01-01T00:00:00Z
