“…Wrathall et al ( 2015 ) while discussing the gravely unequal impacts of climate change state: “Climate-linked stresses threaten to overwhelm regions such as small island developing states (SIDS), coastal settlements and semi-arid regions” (277). Wasko et al ( 2021 ) illustrate how the storm- and flood-related catastrophes caused due to climate change result in economic losses for the people who lose their indigenous livelihood options. Lack of public awareness and unpreparedness of governments further feeds into global adversities (Ismail-Zadeh 2021 ).…”

Pandemics leave their mark quickly. This is true for all pandemics, including COVID-19. Its multifarious presence has wreaked havoc on people's physical, economic, and social life since late 2019. Despite the need for social science to save lives, it is also critical to ensure future generations are protected. COVID-19 appeared as the world grappled with the epidemic of climate change. This study suggests policymakers and practitioners address climate change and COVID-19 together. This article offers a narrative review of both pandemics' impacts. Scopus and Web of Science were sought databases. The findings are reported analytically using important works of contemporary social theorists. The analysis focuses on three interconnected themes: technology advancements have harmed vulnerable people; pandemics have macro- and micro-dimensions; and structural disparities. To conclude, we believe that collaborative effort is the key to combating COVID-19 and climate change, while understanding the lessons learnt from the industrialised world. Finally, policymakers can decrease the impact of global catastrophes by addressing many socioeconomic concerns concurrently.

“…The National Meteorological Administration (NMA) has put floods, droughts, freezing disasters (mainly frost disasters), and winds as the most important meteorological disasters, and the NBS Poverty Monitoring Survey (NMS) also lists and counts these disasters separately. It can be found that there is a strong correlation between climate shocks and economic losses [24].…”

Climate change is widespread, rapid, and is intensifying. Using Chinese disaster data and the China Family Panel Studies (CFPS) data, this study examines the impact of climate shocks on the vulnerability of farm households to poverty and the mechanism of household resource allocation in this process. The results show that (a) climate shocks can significantly increase the poverty vulnerability of farm households. (b) The effect of climate shocks on farm household poverty vulnerability is regionally and individually heterogeneous. Climate non-security zones, risk-averse farmers, and low social capital farmers are more vulnerable to climate shocks and fall into poverty. (c) The mediating effects suggest that climate shocks affect the poverty vulnerability of farm households by influencing their developmental investment, productive investment, and precautionary saving. The paper finally concludes and discusses some policy implications in the national response to climate change and transformation of farmers’ livelihoods.

“…Hydrologic events, such ‘pulses’ or ‘peak periods’ of rainfall or streamflow, have important environmental and ecological functions (Frazier et al, 2003; Tonkin et al, 2019). On the one hand, extreme precipitation events can cause flooding and risk to life (Razavi et al, 2020; Wasko et al, 2021a), but on the other hand, a lack of precipitation events can result in drought, water scarcity, and threaten agricultural production (Vogel et al, 2019). The calculation of hydrologic event characteristics such as event runoff coefficients can describe runoff generation processes and classify catchment behaviour (Merz et al, 2006; Tarasova et al, 2018; McMahon and Nathan, 2021).…”

Identification and pairing of hydrologic events form the basis of various analyses, from identifying events for the calibration of hydrologic models, to calculation of event runoff coefficients for catchment characterization. Despite this, there is no unified approach for identifying hydrologic events. Here, using the R package, hydroEvents (https://cran.r-project.org/package=hydroEvents), we compare multiple methods of extracting and pairing hydrologic events focussing on the relationship between rainfall and runoff. We find the four common analytical approaches used to identify runoff events—based on either event threshold, local maxima/minima, or proportion of baseflow contribution, give similar results. However, when rainfall events are paired to runoff, the type of algorithm and the direction of pairing (either from rainfall to runoff, or runoff to rainfall) make a considerable difference to the final event pairs identified and resulting analyses. Here, we demonstrate the value of automated event extraction and pairing algorithms for large‐sample hydrology analysis by calculating event runoff coefficients across Australia. Our results show that climatology is a key driver of catchment rainfall‐runoff response with much of Australia dominated by excess rainfall runoff generation. However, our results also show that the variability due to pairing method can introduce a variability equal to that of the climatology due to biasing the runoff mechanism within the sample. With this analysis we demonstrate the importance of systematic and consistent approaches to hydrologic characterization when identifying and pairing hydrological events.
