A review of technical and social methods for observing and monitoring extreme rainfall events

Recent extreme weather events driven by climatic variation and change have severely impacted infrastructure, human life, and ecosystems globally, increasing the urgency for Early Warning Systems (EWS) and hybrid methods to observe extreme rainfall events. This article reviews existing studies on technical and social methods for monitoring extreme rainfall to explore the integration of these approaches in rainfall observation. Given the limitations of technical and social methods when used in isolation, it has become evident that hybrid approaches that integrate social and technical methods could enhance preparedness for catastrophic rainfall events. Therefore, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method was employed to identify and analyse studies on rainfall observation. A total of 3786 articles were identified from different databases, and after applying various filters, 144 studies were selected and analysed to improve our understanding of rainfall monitoring approaches. The key findings of this review indicate four main trends: (1) technical methods dominate over social methods because of their perceived reliability and precision; (2) in the Global North, only technical methods are used, with no recorded studies incorporating social approaches; (3) social methods, along with integrated approaches, are more prevalent in the Global South; and (4) integrated methods remain limited despite their potential to enhance rainfall monitoring. This review provides insights into the benefits of combining technical and social methods, highlighting their complementary strengths. By bridging the gap between high-tech solutions and community-based monitoring, integrating these approaches could improve EWS and strengthen climate resilience. Contribution: This review addresses the gap in integrating technical and social methods for rainfall monitoring, emphasising their complementary strengths. It highlights the limited use of integrated approaches, particularly in the Global North, despite their potential to enhance EWS. This research advocates for inclusive and effective climate risk management by bridging high-tech solutions with community-based monitoring

Investigating the socioeconomic impacts of sewage spillages on businesses in the Umhlanga Rocks coastline area

Sewage spillage is fast becoming a significant concern in South Africa because of the deteriorating infrastructure and substandard service delivery. Thus, this study investigated the socioeconomic impacts of sewage spillages on businesses in the Umhlanga Rocks coastline area. A questionnaire with open and closed-ended questions was used to collect data from business owners in the affected area. One hundred business owners were handed questionnaires to complete, and 95 completed questionnaires were collected. The qualitative data from the questionnaires were analysed using thematic analysis, whereby line-by-line coding was manually completed using Excel. The quantitative data were analysed in R studio using numerous statistical tests, including the Shapiro–Wilk test, the Chi–square test, the Kruskal–Wallis test, Dunn’s test, and Cohen’s d test. The thematic analysis and statistical testing results showed that sewage spillages disrupted businesses significantly. Results indicated that businesses of different sizes experienced socioeconomic losses differently. Consequently, the results of this study have implications for business owners and communities living in the affected area. Moreover, findings have revealed practical strategies and interventions that may be used by micro- to medium-scale businesses to mitigate the socioeconomic impact of sewage spillages. Contribution: The practical strategies revealed in this study contribute to reducing the vulnerability of communities and businesses to sewage spillages. Findings of the study have also been disseminated to the business owners and other relevant stakeholders to provide them with alternative solutions in ‘softening the blow’ caused by the spillages

Factors associated with financial security, food security and quality of daily lives of residents in Nigeria during the first wave of the COVID-19 pandemic

An online survey was conducted to identify factors associated with financial insecurity, food insecurity and poor quality of daily lives of adults in Nigeria during the first wave of the COVID-19 pandemic. The associations between the outcome (experience of financial loss, changes in food intake and impact of the pandemic on daily lives) and the explanatory (age, sex, education level, anxiety, depression, HIV status) variables were determined using logistic regression analysis. Of the 4439 respondents, 2487 (56.0%) were financially insecure, 907 (20.4%) decreased food intake and 4029 (90.8%) had their daily life negatively impacted. Males (AOR:0.84), people who felt depressed (AOR:0.62) and people living with HIV -PLHIV- (AOR:0.70) had significantly lower odds of financial insecurity. Older respondents (AOR:1.01) had significantly higher odds of financial insecurity. Those depressed (AOR:0.62) and PLHIV (AOR:0.55) had significantly lower odds of reporting decreased food intake. Respondents who felt anxious (AOR:0.07), depressed (AOR: 0.48) and who were PLHIV (AOR:0.68) had significantly lower odds of reporting a negative impact of the pandemic on their daily lives. We concluded the study findings may reflect a complex relationship between financial insecurity, food insecurity, poor quality of life, mental health, and socioeconomic status of adults living in Nigeria during the COVID-19 pandemic

Factors associated with COVID-19 pandemic induced post-traumatic stress symptoms among adults living with and without HIV in Nigeria: a cross-sectional study

Background: Nigeria is a country with high risk for traumatic incidences, now aggravated by the COVID-19 pandemic. This study aimed to identify differences in COVID-19 related post-traumatic stress symptoms (PTSS) among people living and not living with HIV; to assess whether PTSS were associated with COVID-19 pandemic-related anger, loneliness, social isolation, and social support; and to determine the association between PTSS and use of COVID-19 prevention strategies.Methods: The data of the 3761 respondents for this analysis was extracted from a cross-sectional online survey that collected information about mental health and wellness from a convenience sample of adults, 18 years and above, in Nigeria from July to December 2020. Information was collected on the study's dependent variable (PTSS), independent variables (self-reported COVID-19, HIV status, use of COVID-19 prevention strategies, perception of social isolation, access to emotional support, feelings of anger and loneliness), and potential confounder (age, sex at birth, employment status). A binary logistic regression model tested the associations between independent and dependent variables.Results: Nearly half (47.5%) of the respondents had PTSS. People who had symptoms but were not tested (AOR = 2.20), felt socially isolated (AOR = 1.16), angry (AOR = 2.64), or lonely (AOR = 2.19) had significantly greater odds of reporting PTSS (p p Conclusion: The present study identified some multifaceted relationships between post-traumatic stress, HIV status, facemask use, anger, loneliness, social isolation, and access to emotional support during this protracted COVID-19 pandemic. These findings have implications for the future health of those affected, particularly for individuals living in Nigeria. Public health education should be incorporated in programs targeting prevention and prompt diagnosis and treatment for post-traumatic stress disorder at the community level.</p

Sex differences in the experience of COVID-19 post-traumatic stress symptoms by adults in South Africa

Abstract Background The COVID-19 pandemic has created multiple mental health challenges. Many residents in South Africa face pre-existing elevated levels of stress and the pandemic may have had varying impacts on sub-populations. The aims of this study were to determine: 1) the factors associated with post-traumatic stress symptoms (PTSS) and 2) sex differences in the factors associated with PTSS in adults residing in South Africa during the COVID-19 pandemic. Methods Study participants aged 18 years and above, were recruited for this cross-sectional study through an online survey implemented from June 29, 2020 to December 31, 2020. The outcome variable was PTSS; explanatory variables were sex at birth, COVID-19 status, social isolation and access to emotional support. Confounders considered were age, education level completed and current work status. Logistic regressions were used to determine the association between the outcome and explanatory variables after adjusting for confounders. Outcomes There were 489 respondents. Among all respondents, those who were older (AOR: 0.97; 95% CI: 0.95 – 0.99) and had access to emotional support from family and relatives (AOR: 0.27; 95% CI: 0.14 – 0.53) had significantly lower odds of PTSS. Respondents who felt socially isolated had higher odds of PTSS (AOR: 1.17; 95% CI: 1.08 – 1.27). Females had higher PTSS scores and higher odds of PTSS compared to males (AOR: 2.18; 95% CI: 1.41-3.39). Females (AOR: 0.27; 95% CI: 0.08 – 0.95) and males (AOR: 0.26; 95% CI: 0.11, 0.59) who had access to emotional support had significantly lower odds of PTSS than those who had no support. Females (AOR: 1.15; 95% CI: 1.04 -1.27) and males (AOR: 1.19; 95% CI: 0.11, 0.59) who felt socially isolated had higher odds of PTSS compared to those who did not feel socially isolated. Interpretation Compared to males, females had higher scores and higher odds of reporting PTSS during the COVID-19 pandemic. Access to emotional support ameliorated the odds of having PTSS for both sexes, while feeling socially isolated worsened the odds for both sexes. </jats:sec

Social media information and its association with the adoption of COVID-19 preventive measures in four Latin American countries

The study aimed to assess the association between adherence to COVID-19 preventive measures and access to media information related to COVID-19. A multicountry, cross-sectional study using an online survey was conducted from June to December 2020. The sample included 1,457 participants from Argentina, Brazil, Chile, and Mexico. The outcome variable was self-reported adherence to preventive measures (handwashing, social distancing, self-isolation, use of face masks, and working from home). The explanatory variable was self-report of following media information related to COVID-19 (watching or reading the news, following social media coverage). Multivariable logistic regression analyses were conducted to determine the associations. Following information on social media was positively associated with higher odds of practicing social distancing [adjusted odds ratio (AOR) = 5.39; 95% confidence interval (CI): 3.93–7.30], self-isolation (AOR = 1.44; 95% CI: 1.08–1.92), use of face masks (AOR = 16.84; 95% CI: 10.03–28.27), handwashing (AOR = 6.95; 95% CI: 4.98–9.71), and working from home (AOR = 1.85; 95% CI: 1.43–2.41). Differences in the use of social media for COVID-19 information were observed among the four countries. Following social media was positively associated with adherence to COVID-19 preventive measures in Latin America. Social media may be used effectively for COVID-19 behavior modification in Latin AmericaPeer reviewe

Associations between sexual orientation, financial security and relationships with family and peers during the COVID-19 pandemic in Nigeria

Background: This study aimed to determine whether factors associated with financial insecurity during the COVID-19 pandemic were associated with worsening relationships with family, peers and friends of sexual minorities living in Nigeria. Methods: Data were collected using an online survey conducted from 29th June to 31st December 2020. The outcome variable was the quality of relationship with family, friends and peers during the COVID-19 pandemic. The explanatory variables were the sexual orientation (lesbian, gay, bisexual, heterosexual), COVID-19 status, and financial security (job loss or reduced/lost wages because of the COVID-19 pandemic). Multilevel logistic regression analysis models with robust estimation were built and used to assess the association between the outcome and explanatory variables. The models were adjusted for sociodemographic profile (age, sex at birth, education status). Results: Being a sexual minority was associated with higher odds of worsened relationship with family (AOR: 1.49) and friends and peers (AOR: 2.38) during the pandemic. Having COVID-19 symptoms but not getting tested was significantly associated with higher odds of reporting worsening of the relationship with family (AOR: 1.69) and history of job loss (AOR: 1.68), while having formal education (p&lt;0.05) was significantly associated with lower odds of reporting worsening of the relationship with family. The factors significantly associated with higher odds of reporting worsened relationship with friends and peers were testing positive for COVID-19 (AOR: 1.60), reduced wages (AOR: 1.24), and being older (AOR: 1.01). Attaining a college/university education was significantly associated with lower odds of worsened relationship with friends and peers (AOR: 0.31). Conclusions: The COVID-19 pandemic may increase the risk of negative disruptions in the relationships with family, friends and peers, especially for sexual minorities. National COVID-19 response programs should include plans to support those who face social disruption in managing the crisis.</ns3:p

Fear of contagion, emotional stress and coping strategies used by adults during the first wave of the COVID-19 pandemic in Nigeria

BACKGROUND: The COVID-19 pandemic has induced high levels of stress. The aim of the study was to assess the relationship between emotional stress (COVID-19 related fear, anger, frustration, and loneliness) and the use of coping strategies among adults in Nigeria during the COVID-19 pandemic. METHODS: Data from adults aged 18 years and above were collected through an online survey from July to December 2020. The dependent variables were COVID-19 related fear (fear of infection and infecting others with COVID-19), anger, frustration, and loneliness. The independent variables were coping strategies (use of phones to communicate with family and others, video conferencing, indoor exercises, outdoor exercises, meditation/mindfulness practices, engaging in creative activities, learning a new skill, following media coverage related to COVID-19) and alcohol consumption. Five logistic regression models were developed to identify the factors associated with each dependent variables. All models were adjusted for sociodemographic variables (age, sex at birth, and the highest level of education). RESULTS: Respondents who consumed alcohol, followed media coverage for COVID-19 related information, and who spoke with friends or family on the phone had higher odds of having fear of contracting COVID-19 or transmitting infection to others, and of feeling angry, frustrated, or lonely (p < 0.05). Respondents who exercised outdoors (AOR: 0.69) or learned a new skill (AOR: 0.79) had significantly lower odds of having fear of contracting COVID-19. Respondents who practiced meditation or mindfulness (AOR: 1.47) had significantly higher odds of feeling angry. Those who spoke with friends and family on the phone (AOR: 1.32) and exercised indoors (AOR: 1.23) had significantly higher odds of feeling frustrated. Those who did video conferencing (AOR: 1.41), exercised outdoors (AOR: 1.32) and engaged with creative activities (AOR: 1.25) had higher odds of feeling lonely. CONCLUSION: Despite the significant association between emotional stress and use of coping strategies among adults in Nigeria during the COVID-19 pandemic, it appears that coping strategies were used to ameliorate rather than prevent emotional stress. Learning new skills and exercising outdoors were used to ameliorate the fear of contracting COVID-19 in older respondents

Associations between mental health challenges, sexual activity, alcohol consumption, use of other psychoactive substances and use of COVID-19 preventive measures during the first wave of the COVID-19 pandemic by adults in Nigeria

Background The aims of this study were to assess: 1) the associations among sexual activity, alcohol consumption, use of other psychoactive substances and mental health during the COVID-19 pandemic; and 2) the associations between COVID-19 preventive measures, alcohol consumption and use of psychoactive substances. Methods This was a secondary analysis of data collected from adults in Nigeria between July and December 2020. The variables extracted included change in sexual activity, alcohol consumption and use of other psychoactive substances, COVID-19 preventive behaviors (wearing face masks, washing hands, physical distancing), anxiety, depression, post-traumatic stress disorder (PTSD) and sociodemographic variables (age, sex, education, HIV status, employment status). Multivariable logistic regressions were conducted. A model was run to regress depression, anxiety, PTSD, increased alcohol consumption, and increased use of other psychoactive substances, on increased sexual activity. In separate models, anxiety, depression, and PTSD were regressed on increased alcohol consumption and on increased use of other psychoactive substances. Finally, three models were constructed to determine the associations between increased alcohol consumption and increased use of other psychoactive substances on three separate COVID-19 preventive behaviors. All models were adjusted for sociodemographic variables. Results Increased alcohol consumption (AOR:2.19) and increased use of other psychoactive substances (AOR: 3.71) were significantly associated with higher odds of increased sexual activity. Depression was associated with significantly higher odds of increased alcohol consumption (AOR:1.71) and increased use of other psychoactive substances (AOR:3.21). Increased alcohol consumption was associated with significantly lower odds of physical distancing (AOR:0.59). Conclusion There was a complex inter-relationship between mental health, sexual health, increased use of psychoactive substances. The consumption of alcohol also affected compliance with physical distancing. Further studies are needed to understand the observed relationships.Peer reviewe
