“…(4) In this study, a specific industry in vulnerable areas is assumed to suffer consistently from flood‐related losses, implying that variations in the industry’s losses among regions are insignificant. Indeed, these industries are distributed over YREB, with the data on the exact locations for production capacities of each affected sector being available from the background information of regional IO tables (Han et al., 2021; Tan & Bi, 2018; Zhai et al., 2021). Neglection of regional differences in approaching flood‐related losses can lead to an overestimation of TGP’s impact in this study.…”

Climate change has resulted in an increasing number of natural catastrophes during the last few decades, such as heatwaves (Z. Li et al., 2018), hurricanes (Weinkle et al., 2018), drought (Trenberth et al., 2014), and especially floods (Mallakpour & Villarini, 2015). Floods have been recognized as the most prevalent natural catastrophe, posing a hazard to the majority of locations worldwide. Floods accounted for 40% of all weather-related disasters, affecting over 1.65 billion people over the previous two decades, while the number of floods around the world has climbed from 1,389 to 3,254 (UN Office for Disaster Risk Reduction, 2020). Thus, although the construction of large-scale hydraulic projects (LHPs) not only is time-consuming but also requires numerous human and material resources, many LHPs have been built in both developed and developing countries to improve river basin flood-resilience and promote flood-risk management. Under such circumstances, it becomes critical to investigate the comprehensive effects of LHPs during and after floods, as well as to develop cost-effective postflood adaptation and mitigation strategies.It is preferable to have a solid understanding of how to estimate the flooding losses in order to be aware of LHPs' economic flood-retention impacts. Many recent studies have focused on the direct social and economic impacts of natural catastrophes (e.g., the loss of life and tangible possessions; Okuyama, 2014). Direct economic losses resulting from natural hazards were typically assessed by government authorities or insurance companies based on first-hand data surveys and interviews (Ansell & Valle, 2021), or disaster models. However, the direct losses during a flood event only account for a small portion of total losses, whereas indirect losses may impose a much longer and larger impact (Cunado & Ferreira, 2014;Okuyama & Santos, 2014). Some approaches have been developed to analyze such indirect losses. Zeng et al. (2019) distinguished the main approaches for estimating the indirect flood losses of a natural disaster, such as postdisaster economic surveying (Molinari et al., 2014), econometric modeling (Cavallo et al., 2013, input-output (IO) models (Miller & Blair, 2009), and computable general equilibrium (CGE) models (Rose & Liao, 2005). Since the first two methods inevitably require primary data sources and can hardly capture the complex interrelationships in the socioeconomic system, academics preferred the IO and CGE models for investigating indirect flood losses (Koks & Thissen, 2016). However, the IO approach

“…First, to increase yields to supply the growing population, farmlands in China (e.g., in the Huaihe River Basin) used to apply large of fertilizers (highly soluble ammonia fertilizers in particular), which drained into waterways and increased total nitrogen pollution 46 . Second, products (including these chemical fertilizers) are manufactured in industrial areas (mainly in the Haihe, Songhua & Liaohe, and Yangtze downstream River Basins), where large numbers of chemical compounds are discharged into water as part of their production processes 47 . Third, domestic sewage discharge is also high in these areas because of the high population density 48 .…”

Little is known about the association between surface water quality and cancer incidence, especially in China. Drinking water quality has been linked to the incidence of several cancers in individual-level studies. However, few studies have attempted to examine multiple pollutants and multiple cancers at population level. This study used water monitoring and population-level cancer data from across China to examine spatial associations between water pollutants and types of cancer. We found a “dose–response” relationship between the number of pollutants present at high levels and cancer incidence. These results provide evidence of a nationwide spatial association between water quality and cancer in China. The precise relationship varies with cancers and pollutants. However, the overall consistency of the “dose–response” relationship suggests that surface water quality is an important factor in cancer incidence. Our findings highlight new issues such as the changing effects when different pollutants co-exist and an increasing number of new cancer cases partially attributable to poor water quality. Our work also points to some ways to deal with these challenges.

“…Wastewater discharges from industrial, commercial and domestic sources pollute rivers with nutrients, pathogens, toxins, and other contaminants if not properly treated before release (Osibanjo et al, 2011;Edokpayi et al, 2017;Huang et al, 2019). Sewage may contain pharmaceutical residues and antibiotic resistant bacteria that persist in aquatic environments (Ternes et al, 2015;Kuang et al, 2020).…”

This paper presents the theoretical study of forced Van der Pol oscillator equation. Oscillatory systems are studied to know measures that can reduce the amplitude of oscillation of the oscillatory system. Here, multiple two-timing regular parameter perturbation is applied since it is a kind of perturbation among other perturbation techniques that enables the study of the behaviour of a system under certain conditions. Asymptotic expansion technique was also applied. Excel Microsoft was used to analyse the uniformly valid asymptotic solution of the Van der Pol oscillator equation obtained. The uniformly valid asymptotic solution in the independent variable obtained, showed that damping alters the amplitude of the oscillatory system thereby affecting its motion. Increase in damping decreases the amplitude of oscillation of the system. With damping incorporated in the system though very small damping, the amplitude of oscillation reduces with time.
