The implementation of Good Agricultural Practices (GAPs) in developing countries, particularly Tanzania, requires strong government intervention to achieve sustainable agricultural outcomes in line with both national and international standards. Given the high costs and institutional demands associated with GAP implementation, the central–local government interface plays a critical role in facilitating, coordinating, and overseeing this process. This formal interface comprises key dimensions, including the transfer of authority, interaction channels, adherence to existing legislation, and resource-sharing mechanisms. However, limited understanding of how these institutional arrangements influence the effective implementation of GAPs has contributed to persistent inconsistencies and inefficiencies. This study investigated the extent to which Tanzania’s formal central–local government interactions affect GAP implementation. A total of 228 respondents were surveyed across Local Government Authorities in the Morogoro, Mbeya, and Shinyanga regions, and data were analysed using multiple linear regression. The results demonstrate that the transfer of authority (? = 0.124, p < 0.05), interaction channels (? = 0.540, p < 0.001), and resource-sharing mechanisms (? = 0.134, p < 0.001) significantly influence the implementation of GAPs. In contrast, adherence to existing laws and regulations showed no statistically significant effect (? = 0.018, p = 0.587). These findings underscore the importance of decentralised authority, effective intergovernmental communication, and coordinated resource allocation in strengthening agricultural governance. The study recommends more targeted policy reforms that empower local governments and foster institutional synergy to enhance GAP implementation, thereby contributing to Tanzania’s agricultural transformation and broader development objectives. It is therefore, the study reinforce the need for integrated governance as a pathway to achieving agricultural modernisation and food security goals in line with SDG 2.

This study investigates the effects of revenue enhancement plans (REPs) on revenue collection performance in Tanzanian local government authorities (LGAs), focusing on Mwanza City Council, Manyara Urban Council, and Mbeya City Council. The research adopts a mixed approach, collecting data from 400 respondents using a multistage sampling technique. The data were analyzed using a multivariate ordered probit model. The results reveal that reducing revenue leakage and improving revenue forecasting accuracy significantly enhance revenue collection performance. Specifically, the coefficient for revenue leakage was -1.221 for effectiveness (p<0.01) and -1.59 for increment (p<0.01), indicating a strong negative impact on performance. In contrast, accurate revenue forecasting positively impacted effectiveness (1.390, p<0.01) and increment (0.516, p<0.01). The model also showed that high implementation costs negatively impacted revenue growth (increment: -1.634, p<0.05). Compliance was found to positively influence reliability (1.533, p<0.01) and efficiency (1.029, p<0.01), underlining the importance of adherence to regulations. The results also highlighted the need for cost management strategies, as implementation costs and leakages hinder revenue growth and efficiency. The study recommends policy measures such as adopting digital solutions to reduce revenue leakages, investing in forecasting tools, and strengthening compliance mechanisms to optimize revenue collection and improve financial sustainability.

Land distribution is a key factor in income inequality in rural areas of developing countries. This study examines the impact of land tenure security on household income and its distribution in Iringa district, Tanzania, focusing on the Certificate of Customary Right of Occupation (CCRO). Using a quasi-experimental design and Propensity Score Matching, 404 respondents were randomly selected and divided into groups with and without CCROs. Both quantitative and qualitative data were collected through surveys and in-depth interviews. Analysis using SPSS/STATA revealed that households with CCROs had higher agricultural yields, sales, and lower production costs. They also invested more in modern farming techniques and soil conservation, leading to higher incomes and reduced income inequality. Despite over 50,000 CCROs issued, credit access remains limited due to a lack of awareness and additional collateral requirements. The study concludes that secure land rights are vital for economic growth and poverty alleviation. Recommendations include increasing awareness about CCROs, facilitating their use as collateral, and exploring barriers to credit access for CCRO holders. Further research is needed to address these challenges.

This paper uses a multinomial endogenous treatment effect model and data from a sample of 470 farming households to assess the impacts of adopting sustainable agricultural practices (SAPs) on farm yield and household incomes among smallholder maize farmers in Morogoro region. Results show that combination of improved maize and crop residual significantly increased maize yield by 46%, while intercropping with crop residual (65%), improved maize seeds with manure use (58%), and maize rotation with intercropping (57%). The model estimates indicate that individual elements of SAPs increased yield by crop residual (30%), crop rotation (38%), improved maize varieties (85%), intercropping (58%), and manure (43%) whereas, the application of bundled SAPs had significant impacts on the household income via the following combinations; maize-legume rotation and crop residual (50%), improved maize and crop residual (46%), improved maize and manure (70%), maize-legumes rotation and improved maize (46%), maize rotation and intercropping (68%), maize rotation, improved maize, crop residual, and intercropping (41%), and lastly improved maize, intercropping, manure, crop residual, and crop rotation (55%). The study recommends actors involved in the design, promotion and dissemination of SAPs to find a suitable mix or combination of these practices that will enhance maize productivity and incomes, while simultaneously addressing issues related to the dis-adoption of SAPs, and climate change, by raising awareness and educating to farmers about the benefits of using SAPs and implementing mitigative measures for climate change. This includes providing financial incentives such as loans and subsidies, as well as conducting policy reforms to evaluate and adjust policies that currently favor the use of conventional practices in Tanzania.

The study, using a comparative case study design, explored the attitude of local direct beneficiaries concerning the cessation of resources for two donor-funded agriculture-related projects in Tanzania from a Social Cognitive Theory perspective. Using a 5-point Likert Scale, data from 274 respondents were collected and analysed. Before data analysis, validity and reliability tests were performed and determined to be good. Descriptive statistics including percentages and frequencies were done. Additionally, a chi-square test was done to establish the association between variables. The findings show that local beneficiaries with higher self-efficacy and wider outcome expectancies had a positive attitude as opposed to their counterparts. Also, a positive significant relationship existed between self-efficacy and attitude (P<0.01) and between outcome expectancies and attitudes (P<0.05). Equipping local beneficiaries with the competencies needed to solve problems on their own and the continued functioning of VBAAs can aid local beneficiaries in maintaining a positive attitude post-project resources withdrawal. The study recommends that a transition phase is critical for project implementers to solidify benefits and benefit-enhancing behaviours. Also promoting community-based extension services by institutionalising VBAAs within the LGAs should be given a priority for enhancing sustainability.
