In Africa the problem is much severe to the extent that farmers are abandoning the crop. Controlling T. absoluta by use of chemical pesticides is profoundly tricky due to development of rapid resistance. Alternative options such as biological controls are either scarce or expensive and only a handful of microbial agents are currently registered for management of T. absoluta in Africa. It has been observed that T. absoluta causes damage and loss in tomato ranging from 50-100% in South America, Europe and Africa where management options are most limited. Although several synthetic pesticides are registered for management of T. absoluta including; chlorantraniliprole spinetoram and emamectin benzoate group, little success are reported in Africa due to various factors including fast resistance development of T. absoluta.

Tomato (Solanum lycopersicum L.) is an important vegetable crop for income and nutrition of smallholder farmers in sub-Saharan Africa. However, it is attacked by many insect pests that cause high economic losses. This review focuses on one insect pest, namely Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae). Many studies have shown that chemical pesticides have failed to control tomato leafminer in many parts of the world including America, Europe, Asian and Sub-Saharan Africa, where the pest is impacting significantly the tomato value chains as farmers were unaware of the pest and unprepared to control it. The review has also evaluated current approaches used to manage T. absoluta in different countries and proposes areas for future investment in research for effective and affordable management to prevent further losses caused by T. absoluta in tomato production is Sub- Saharan Africa.

Local Government Authorities (LGAs) are crucial in translating national climate policies into local climate adaptation actions. While research indicates that trust influences support, attitudes, and behaviours regarding climate and environmental policies, few studies treat trust as a multidimensional concept directly linked to the implementation of local climate adaptation. Based on the organizational trust theory and policy implementation theory, this study examines how three aspects of perceived organizational trust, competence, benevolence, and integrity influence the perceived implementation of CCAS. A mixed-methods approach was employed, combining survey responses from 351 village development committee members with insights from twenty key informant interviews and six focus group discussions. Data analysis involved PLS- SEM and thematic analysis. Findings indicate that perceived benevolence and perceived integrity positively influence the perceived implementation of CCAS, whereas perceived competence does not. The study concludes that positive evaluations of local CCAS implementation are more strongly associated with perceptions of benevolence and integrity than with perceptions of competence. The study contributes to climate governance and policy implementation research by indicating that trust in LGA operates through multiple dimensions in shaping the perception of local climate adaptation implementation. The study suggests that more positive perceptions of local climate adaptation implementation may be strengthened where LGAs adopt practices that enhance their perceived integrity and benevolence, such as community oversight, participatory budgeting, capacity building and responsiveness to community climate adaptation priorities. https://doi.org/10.1016/j.sbr.2026.100196 Received 9 March 2026; Received in revised form 28 May 2026; Accepted 3 June 2026 Available online 6 June 2026 3051-0643/© 2026 Elsevier Ltd.

The job commitment of student counsellors is crucial in Tanzanian universities, as they play a vital role in supporting students' academic, personal, and career development, addressing issues that can impact their wellbeing and performance. This study aimed to investigate the impact of work-life conflict on job commitment among student counsellors in higher education institutions in Tanzania. The study aimed to examine the influence of work-to-family conflict, family-to-work conflict, and gender differences on job commitment among student counsellors. The study employed an explanatory research design using a mixed-methods research approach. In this study, both quantitative and qualitative data were collected through a structured questionnaire and an interview guide. The target population of 179 student counsellors was purposely selected, resulting in a sample size of 83 respondents obtained through the Yamane Formula. Quantitative data analysis included descriptive and inferential statistics, where Spearman correlation and regression analysis were used to summarise, explore, and make inferences. Likewise, qualitative data were analysed thematically to understand patterns and meanings within textual or observational data. The findings showed a significant correlation between work-life conflict and all employee commitment factors. Furthermore, the findings reveal that work-family conflict significantly contributed to employee commitment, with work-to-family interference found to be higher than family-to-work conflict among student counsellors. Furthermore, based on work-family role conflict, the results indicate a considerable difference in organisational commitment between male and female respondents. Based on the study's findings, an organisational support program should be developed and made available to all student counsellors to lessen the strain of role conflict between work and family and to encourage their job commitment practically. 2025-01-01T00:00:00Z
