    Assessing livelihood vulnerability and adaptation to climate variability and change among farming households in Plateau State, north-central Nigeria
    (University of the Witwatersrand, Johannesburg, 2024) Hassan, Buhari; Knight, Jasper
    It has been projected that sub-Saharan Africa would be severely affected by climate change in form of persistent and increasing climate variability. Nigeria’s situation as a developing country coupled with the fact that agricultural activities are primarily rainfed, provides a suitable case study in which to assess the vulnerability of farming households to climate variability and change. Lack of data on the nature and extent of vulnerability to climate variability (particularly annual changes in rainfall and temperature patterns) on food production systems and livelihoods in Nigeria hinders the development of effective policies to mitigate the adverse impacts of climate change and variability. The study aims to improve understanding of the socio-economic, institutional, biological and physical factors that contribute to vulnerability of farming households to climate change and variability in Nigeria. By combining descriptive, participatory and statistical analysis as well as field observations, this research develops a holistic approach to assess the level of exposure, sensitivity and adaptive capacity of farming households. Multistage sampling was used to purposely select communities in Bokkos Local Government Area, Plateau State, for the study, while farming households were randomly selected for the household questionnaire survey within four communities. Purposive sampling was used to identify key informants for interviews. Observation and taking photographs of farmers’ activities were used to complement the other data collection methods. Qualitative data was analysed using descriptive and content analysis, while the quantitative data was analysed using the Statistical Package for Social Sciences (SPSS) (v 27) and Microsoft Excel (v2020). The level of vulnerability of farming households was determined using the Sustainable Livelihood Approach. Results show that farmers are exposed to climate variability in form of changing rainfall patterns which includes late onset of rains, dry spells, and early cessation of rains and crop loss due to pests and disease infestation. Results show that the vulnerability of farming households can be linked to access to household livelihood capital assets and that households are characterised by low levels of financial, social and physical capital. Smallholder farming households adopt a range of on-farm and off-farm adaptation strategies including changing planting time, crop diversification, engaging in irrigation farming, intensifying the use of fertilizers, manure and agro-chemicals to boost crop yield, and planting of disease-resistant and drought-tolerant crop varieties. Farming households experience a number of challenges which include a lack of financial resources which has a strong influence on enhancing other capital assets such as physical and natural capitals; poor access to mechanised agricultural equipment, lack of training on how to deal with climate change and variability, limited access to improved crop varieties as well as a lack of institutional support, which constitute serious barriers to adaptation to climate variability. In applying these results to climate change adaptation it is recommended that policymakers need to institute specific and implementable climate change adaptation policies that will enable farmers to utilize their capital assets on effective adaptation measures and also engage in viable alternative livelihood diversification strategies, enhance agricultural productivity and resilience and improve institutional support including access to information and training

    Predictors of COVID-related Risk and Resilience in South African Young Adults
    (University of the Witwatersrand, Johannesburg, 2023-06) Benvenuti, Sabrina Lucia; Cockcroft, Kate
    The Coronavirus Disease of 2019 (COVID-19) pandemic has been a lengthy and stressful event for people worldwide, placing increased strain on vulnerable populations. This prompts interest in the field of risk and resilience research. There are several apparent gaps in resilience research such as in the context of a pandemic, and in adult and non-western populations. This research report aimed to identify socio-demographic variables that predict risk and resilience outcomes in young, emerging South African adults, following the COVID-19 pandemic. This study fell into a post-positivist paradigm and used a quantitative, non-experimental, correlational, ex-post facto design. Descriptive, correlational and regression analyses were conducted to identify possible socio-demographic predictors of risk and resilience outcomes in this given population. Overall, the sample population exhibited low-moderate levels of depression, and on average displayed high levels of resilience, overall and across individual, relational and contextual resilience Several significant correlations and predictors, although weak, were identified for the outcome variables of depression (risk) and resilience (at individual, relational and contextual levels) including age, gender and education, pandemic-related and perceived stress, loneliness, parental involvement and warmth, childhood and community experiences. Depression was significantly predicted by gender, perceived stress, loneliness, satisfaction with life and parental involvement, where being female, having stronger feelings of loneliness, and dissatisfaction with life predicted higher levels of depression. Furthermore, parental involvement significantly predicted all five outcomes, where high parental involvement predicted low depression and high resilience across all levels. Perceived stress significantly predicted all but one outcome, namely relational resilience. High levels of perceived stress predicted high levels of depression and poor overall, individual, and contextual resilience. All three levels of resilience were significantly predicted by both parents’ level of education and parental involvement, where levels of maternal education predicted better resilience across all domains, while paternal education had the opposite effect. Identifying such predictors can help to better the knowledge base around risk and resilience in the South African, context and in low- and middle-income contexts. Furthermore, this allows for the targeted implementation of tools and interventions to address these outcomes, such as promoting parental involvement, the implementation of targeted stress-management tools, and more female-focused depression interventions.

    Predictors of resilience among adolescents living in rural Mpumalanga in 2018: a cross sectional study
    (2024) Snijder, Michelle
    Literature suggests that resilience can be reached by practicing behaviours, thoughts and attitudes that promote resilience. To understand which behaviours, thoughts and attitudes foster resilience, predictors of resilience should be studied. This study aimed to examine predictors of resilience among adolescents living in the rural Mpumalanga Province, South Africa. Data were collected using a questionnaire from a sample of 245 adolescents between 13.1 and 15.2 years (median age 14.1 (13.1- 15.2); sex 52.7% female and 47.4% male). The questionnaire included questions from depression, stress and resilience scales as well as additional questions relating to communication with parents, and socio-demographic characteristics. The 20 question Centre for Epidemiological Studies Depression Scale (CES-D) measured depression, the 10-item Perceived Stress Scale (PPS-10) measured stress while the 25-item Connor Davidson Resilience Scale (CD-RISC-25) measured resilience. The prevalence of resilience was estimated at 46.1%. The findings suggest that perceptions of stress did not significantly predict resilience. Experiencing depressive symptoms and healthy interpersonal relationships significantly predicted high resilience. Although healthy relationships with parents predicted high resilience, adolescents relied more on relationships with friends to build resilience. However, regularly meeting with friends predicted low resilience, while always meeting with friends decreased the chances of low resilience. Thus, the study suggests that healthy relationships with both parents and friends may predict high resilience. However, when relationships with friends replaces that of parents, low resilience results. Finally, this study supports the need for further studies on the validity and acceptability of the PPS-10 and CES-D scales in the South African context.
