Abstract

Purpose- This study investigates the influence of environmental sustainability practices in supply chains on the performance of manufacturing firms in Dar es salaam, Tanzania.Design/Methodology- Employing a case study research design, the study utilized a mixed-methods approach, integrating qualitative and quantitative methodologies. A total sample of 155 respondents was selected using simple random sampling for questionnaires, while 13 participants were purposively selected for in-depth interviews. Data collection involved structured questionnaires and interviews, analyzed using descriptive and inferential statistics with SPSS to ensure robust findings. Findings- The findings revealed a positive and significant influence of circular packaging on manufacturing firm performance. Adopting innovative packaging materials and clear disposal instructions can enhance competitive advantage, increase profit margins, and attract environmentally-conscious consumers, leading to higher market share and revenue. Practical Implications- The study highlights the importance of environmental sustainability practices for manufacturing firms in Tanzania. By adopting sustainable approaches, businesses can contribute to a healthier environment, reduce their carbon footprint, and promote responsible consumption. This can have positive implications for both the local community and the global ecosystem. The study recommends that firms invest in circular economic practices, such as innovative packaging and recycling. Policymakers are urged to provide incentives, such as tax relief and subsidies, to support green technologies. Collaboration between public and private sectors to fund research and development is also emphasized. Additionally, consumer advocacy for sustainable products and practices is critical to driving change

Abstract

Background: Despite the prevalence of trust as an important relational governance mechanism in agrifood value chains, previous studies have overlooked its influence on their sustainability, as assessed using the triple bottom line (TBL). Using stakeholder (ST) and Resource Dependency theory (RDT) as theoretical lenses, benevolence and credibility as trust antecedents, and their influence on TBL were assessed, as they have not been explored in the literature. That stands as a novel contribution that enriches the existing scholarly discourse. Objective: This study aims to investigate how farmers' trust toward stakeholders, as reflected in the dimensions of benevolence and credibility, shapes the sustainability of cashew value chains in a developing-country context. Method: A cross-sectional design using a single key informant was used to gather data from 387 cashew nut farmers using a structured questionnaire. The collected data were examined through Partial Least Squares Structural Equation Modeling (PLS-SEM) to evaluate the proposed hypotheses. Results: Of the six hypothesized relations (H1 to H6), H1, H4, H5, and H6 had a positive (+) and significant (P ≤ 0.05) influence on sustainability dimensions, except for H2 and H3, which had positive (+) but not significant (P ≥ 0.05) relationships with sustainability dimensions. Conclusion: Trust is an important governance mechanism for achieving sustainability in cashew nut value chains. Benevolent did not have positive relations with both environmental and social dimensions, hence, attention is needed. Practically, stakeholders with a role in regulating the cashew industry should consider trust as an important factor for achieving sustainability.
