Until the1980s, the wastewater management infrastructure in Chinese cities was virtually neglected. In 1980s, about 20 small-scale wastewater treatment plants were constructed in China that provided low levels of treatment. Wastewater was discharged to open drainage ditches, sometimes temporarily collected in septic tanks and dumped to water bodies without treatment. Impressive investments in this sector began in the 1990s. By 2000 about 400 wastewater treatment plants had been completed and the total treatment capacity increased to almost 40 per cent of wastewater generated in 2003. 2. Despite these significant achievements, wastewater treatment in urban areas results in significant risks for human health and the environment. About two thirds of all urban effluents are still discharged into surface waters without treatment. The odour of sewage is common in Chinese cities, and most rivers and lakes are excessively polluted. This generates water borne diseases, decreases the quality of life, and undermines the attractiveness of cities to foreign investors, and the competitiveness of tourism, water intensive industries, fisheries and agriculture. Moreover, there are some indications that newly-built wastewater treatment plants are not always used efficiently, and that several of them even remain idle because of backlogs in the development of wastewater collection networks, or because of the lack of funding for regular operation and maintenance. 3. The OECD secretariat has examined the financial sustainability and affordability of developing modern, centralised wastewater management infrastructure in medium sized cities and counties in China; This has been done by analysing fourteen cities in Sichuan Province, all located in the basin of the Yangtze river, in the impact

After the site was mapped in 2001, these two ichnotaxa were considered synonyms of Eubrontes and Anomoepus, respectively, the latter designation being the first identification of this ichnogenus in China. The assemblage indicates a typical Jurassic ichnofauna. The present study reinvestigates the site in the light of the purported new ichnospecies Chuanchengpus shenglingensis that was introduced in 2012.

This paper summarizes the Ms 6.0 earthquake disaster that occurred in Changning, Sichuan Province, China, on 17 10 June 2019. Additionally, a description of the disaster emergency response is provided. As determined by on-site investigation and analysis, the direct causes of earthquake casualties are summarized. Among them, 66% of the casualties can be attributed to substandard seismic protection, 25% to improper earthquake risk avoidance, 6% to earthquake-induced geological disasters, and 3% to pre-existing diseases exacerbated by the earthquake. Responding to the causes of these four casualty types, we summarize 4 lessons, which are to build in accordance with seismic protection requirements; strengthen publicity and 15 education awareness of earthquake emergency evacuation and training for the population; investigate and evaluate potential geological disaster sources in the stricken area, along with conducting prevention and control; establish cooperation with health organizations, focusing on people who are older or have serious illnesses and conducting earthquake evacuation training and psychological counselling. 1 Disaster characteristics and disaster situation 20 An Ms 6.0 (Mw 5.8) earthquake struck Changning County, Yibin City, Sichuan Province, China, at 22:55:43 on 17 June 2019 (14:55:43 UTC on 17 June 2019).

Many factors, including rapid urbanization and environmental degra- dation etc, have been challenging the water service delivery in China. Since water scarcity and quality have impact on the poor, reforms to the water ser- vice provision can produce substantial improvements in the living standard of the economically disadvantaged groups. The objective of this study is to crit- ically evaluate the strengths and weakness of China's current water financing and delivering system, with a focus on safeguarding the interests of the poor, and to offer insight into possible solutions.

However, few recent studies in English have focused on the participation subject, scope, ways, and procedure in the EDM of developing countries such as China in the worldwide governance transformation. This study aims to provide an overview of public participation in EDM in China, thus elucidating both the legislation and practice of public participation in EDM in China to a broader audience, as such an overview has not yet been provided. At the beginning of this article, we clarify the key definitions of EDM, public participation and the public, and establish an analytical framework for analyzing public participation in EDM in China. We analyze the scope of the public, the participation scope, ways of participating, and participation procedure in EDM in legislation and practice, through document analysis and empirical survey. We then comment on challenges for public participation in EDM in China—including low public participation in EDM, narrow scope of participation, unbalanced ways of participation, and unreasonable participation procedure.

Journal of Palaeogeography (2021) 10:17 https://doi.org/10.1186/s42501-021-00096-y Journal of Palaeogeography ORIGINAL ARTICLE Open Access The new ichnotaxon Eubrontes nobitai ichnosp. nov. and other saurischian tracks from the Lower Cretaceous of Sichuan Province and a review of Chinese Eubrontes-type tracks Li-Da Xing1,2* , Martin G. Lockley3, Hendrik Klein4, Li-Jun Zhang5, Anthony Romilio6, W. Scott Persons IV7, Guang-Zhao Peng8, Yong Ye8 and Miao-Yan Wang2 Abstract The Jiaguan Formation and the underlying Feitianshan Formation (Lower Cretaceous) in Sichuan Province yield multiple saurischian (theropod–sauropod) dominated ichnofaunas. To date, a moderate diversity of six theropod ichnogenera has been reported, but none of these have been identified at the ichnospecies level. Thus, many morphotypes have common “generic” labels such as Grallator, Eubrontes, cf. Eubrontes or even “Eubrontes- Megalosauripus” morphotype. These morphotypes are generally more typical of the Jurassic, whereas other more distinctive theropod tracks (Minisauripus and Velociraptorichnus) are restricted to the Cretaceous. The new ichnospecies Eubrontes nobitai ichnosp nov. is distinguished from Jurassic morphotypes based on a very well- preserved trackway and represents the first-named Eubrontes ichnospecies from the Cretaceous of Asia. Keywords: Ichnofossils, Dinosaur footprints, Theropod, Myths 1 Introduction are represented by Brontopodus-type tracks.

    International Journal of Environmental Research and Public Health Article An Optimization-Based Approach to Social Network Group Decision Making with an Application to Earthquake Shelter-Site Selection Hengjie Zhang 1, Fang Wang 1, Huali Tang 2 and Yucheng Dong 2,* 1 Business School, Hohai University, Nanjing 211100, China 2 Business School, State Key Laboratory of Hydraulics and Mountain River Engineering, Sichuan University, Chengdu 610065, China * Correspondence: [email protected] Received: 26 June 2019; Accepted: 29 July 2019; Published: 31 July 2019 Abstract: The social network has emerged as an essential component in group decision making (GDM) problems. Thus, this paper investigates the social network GDM (SNGDM) problem and assumes that decision makers offer their preferences utilizing additive preference relations (also called fuzzy preference relations). An optimization-based approach is devised to generate the weights of decision makers by combining two reliable resources: in-degree centrality indexes and consistency indexes. Based on the obtained weights of decision makers, the individual additive preference relations are aggregated into a collective additive preference relation. Further, the alternatives are ranked from best to worst according to the obtained collective additive preference relation. Moreover, earthquakes have occurred frequently around the world in recent years, causing great loss of life and property. Earthquake shelters offer safety, security, climate protection, and resistance to disease and ill health and are thus vital for disaster-affected people. Selection of a suitable site for locating shelters from potential alternatives is of critical importance, which can be seen as a GDM problem. When selecting a suitable earthquake shelter-site, the social trust relationships among disaster management experts should not be ignored.
