Health and Nutrition Literacy among Community Health Workers in Rural and Urban Tanzania: A Comparative Study
Journal ArticleIntroduction: Community health workers (CHWs) are vital in primary health care delivery, especially in low and middle-income countries (LMICs). However, the quality of their services is often questioned due to their limited training compared to professional healthcare providers. Despite evidence of CHWs’ contributions to health and nutrition in Tanzania, the country continues to face high levels of malnutrition and preventive diseases. This underscores the need to evaluate CHWs’ literacy in health and nutrition to enhance their role in promoting these areas. This paper aimed to assess health and nutrition literacy among Community Health Workers (CHWs) in rural and urban Tanzania while exploring factors influencing these literacy levels.
Materials and Methods: This cross-sectional study, conducted in Pwani and Dar es Salaam, Tanzania, involved 194 CHWs, who were obtained using Yamane’s formula for sample size determination. Data was collected via face-to-face interviews using the adapted European Health Literacy Questionnaire (HLS-EU-Q47) for health literacy and the Short Food Literacy Questionnaire (SFLQ) for nutrition literacy. Pearson correlation analysed the association between nutrition literacy (NL) and health literacy (HL), while multinomial logistic regression identified factors influencing HL and NL among CHWs.
Results: Our study found limited health literacy among CHWs to be higher in rural areas (24.5%) than in urban areas (17.6%), while health literacy rates were higher in urban (31.9%) compared to rural (22.9%). Regression analysis showed limited health literacy was significantly associated with age (P = 0.048, OR = 1.041, 95% CI), area of residence (P = 0.002, OR = 0.318, 95% CI) and supervision frequency (P = 0.01, OR = 5.266, 95% CI). Limited nutrition literacy was significantly associated with weekly time spent on CHW activities (P = 0.006, OR = 0.183, 95% CI), age (P = 0.013, OR = 1.050, 95% CI) and area of residence (P = 0.008, OR = 0.387, 95% CI). The correlation between health literacy and nutrition literacy had a Pearson coefficient of 0.517 (P = 0.000).
Conclusion: Our study shows a higher prevalence of limited health and nutrition literacy among rural CHWs than urban ones, with area of residence being the most decisive associated factor. The area of residence is the strongest associated factor for NL and HL. Policymakers can use the identified factors in areas with similar social demographic characteristics to improve community-based health intervention that will, in turn, improve the health and nutrition outcomes of the community
Assessment of food hygiene knowledge, attitude and practices of night street food vendors in Morogoro, Tanzania
Journal ArticleThe consumption of street food is associated with the provision of unhealthy, unsafe, and
nutritionally unbalanced meals, presenting a public health concern. This study was designed to
assess food safety knowledge, attitude and practices of night street food vendors in Morogoro
Municipality. A cross-sectional study involved 256-night street food vendors was performed, using
a structured questionnaire. The results reported that most of the vendors were females (77%) and
half of the vendors were aged between 20 to 30 years. Majority of vendors ,62.9% had been
vending food for 4-5 years. Generally, the study revealed medium attitudes (95.3%) and moderat
The pedagogical implications of ability grouping on students performance in Secondary Schools in Tanzania
International Journal of Humanities and Social Science Invention (IJHSSI) Volume 14 Issue 2, PP. 44-50Students learning abilities vary from one individual to another. This implies that teaching
instructions must be modified to reflect students’ capacities, leading to ability grouping as one of the strategies
for this purpose. This study was conducted to examine the effects of ability grouping in secondary schools in
Tanzania. A descriptive phenomenological design embedded with qualitative approach was used for this study.
Ten secondary school teachers were interviewed for the study, among them five were male and five female
teachers. The findings of the study revealed some various opinions about ability grouping. The positive
implications were shown, whereby, higher-achieving students were grouped in the fixed grouping and some
positive implications when learners in the low-ability group were placed in the mixed grouping. However, there
were also negative effects of ability grouping, whereby ability grouping is not effective as it causes many harms
and damages to students; there are no overall effects of ability grouping on academic performance if students
are grouped by achievement; it is not only ability grouping itself that increases students’ performance but also
the role of peers. It is also not clear whether teachers really use appropriate strategies to instruct groups with
different abilities. Many teachers use the ability approach as a mechanism to identify low achievers in learning;
in some cases, teachers even demoralize lower achievers or pay less attention to the lower achievers, attributing
their poor performance to laziness. Consequently, the tendency towards labelling results in the declining
performances of lower achievers. This study recommends the use of effective practices and alternatives to
ensure equality and access to learning. There is a need to conduct a study to determine teachers’ use of
strategies along with ability grouping
Socio-demographic determinants of climate change adaptation practices in agro-ecological zones: A Case study of Chamwino and Igunga districts, Tanzania
Journal ArticleThe global impacts of climate change have led to the development of various adaptation strategies, including Climate Change
Adaptation (CCA) practices. In Tanzania, the introduction of CCA practices through eco-village projects between 2011 and 2019
reflects ongoing efforts to combat climate change effects. However, scientific understanding of the socio-demographic factors
influencing households' decisions to adopt CCA practices remains limited. This study investigates the influence of sociodemographic
factors on the adoption of CCA practices in the agro-ecological zones of Chamwino and Igunga districts, representing
central and western Tanzania. Data were collected from 295 respondents through household surveys, complemented by key
informant interviews (KIIs) and focus group discussions (FGDs). Socio-demographic factors such as gender, age, education level,
land ownership, and training attendance were analyzed using descriptive statistics. Pearson’s Chi-square test was employed to assess
the statistical significance of the association between socio-demographic factors and agro-ecological zones, while a multivariate
probit model was used to analyze the impact of socio-demographic factors on the adoption of CCA practices. The findings reveal
that CCA adoption varies across zones, with the western zone showing a higher adoption rate. Chi-square results indicated significant
associations between CCA adoption and factors such as soil water conservation, farmyard manure, mixed cropping, plant spacing,
and the use of improved seeds and breeds (p<0.05). The multivariate probit model showed that gender, experience, land ownership,
and training attendance significantly influenced adoption, with these factors promoting more practices compared to age, marital
status, and education level. These insights are crucial for policymakers and local agencies to ensure that CCA initiatives ar e inclusive

Farmers’ willingness to pay for hermetic storage bags: The effects of training and free trial
Journal articleMaize is a staple food for smallholder farmers in Africa, but poor postharvest management leads to high grain
losses, contributing to food insecurity. Improved on-farm storage such as hermetic storage bags can reduce these
losses, yet their adoption remains low. Full one-off subsidies can be an effective development policy to enhance
technology adoption. However, policymakers are often opposed to such subsidies, arguing that it lowers will
ingness to pay (WTP) once the subsidy ends and thereby constrains the future market. Using the Becker-DeGroot-
Marschak (BDM) mechanism to investigate WTP and building on a prior randomized control trial among
smallholders in Tanzania, this study analyzes how prior free distribution influences long-term WTP for hermetic
storage bags (six years later). Additionally, we analyze how offering a deferred payment option influences
farmers’ WTP for hermetic storage bags. We find that the prior provision of free hermetic storage bags had
decreased WTP. As an alternative intervention, we show that providing the opportunity to pay later increases
WTP as compared to immediate payment. The study highlights that free technology provision may reduce future
market engagement but a pay later option can be considered as a valuable policy tool for quick technology

Industrialization and economic development in Tanzania from independence to today: a review of historical strategies, challenges and prospects
South Asian Journal of Social Studies and Economics Volume 22, Issue 7, Page 319-332Tanzania got her independence from the British in 1961, by then, Tanganyika, before joining
Zanzibar in 1964. Tanzania started the move towards industrialization just after the independence
in 1961. The Industrial development in Tanzania is categorized in various phases namely
immediately after independence, during Ujamaa na kujitegemea (Socialism & Self-reliance
ideology) after the Arusha Declaration of 1967, economic and political reforms in mid 1980s,
beyond 1996 - privatization and establishment of private sectors, and free market economy period to date. The Industrial Development in Tanzania was strengthened in 2000s when the Tanzania
Development Vision (TDV) 2025 was formulated with the aim of enabling the country to reach the
semi-industrialized economy by 2025. Various strategies and economic development plans have
been formulated in order to meet the TDV 2025. Many industrial development efforts were
observed such as constructions of infrastructures such as buildings for offices, hotels, roads,
railways, marine facilities, purchasing of airplanes, and establishment of power energy plants and
service delivery facilities. However, the Industrial Development sector faced a number of
challenges. The challenges include lack of capital, Inadequate supply of power, lack of technical
skills, discontinuation of policies between succeeding regimes, price fluctuation, unstable
currencies, corruption and economic crises due to various shocks such as the Tanzania –Uganda
war of 1978/1979. However, the Industrial development in Tanzania keeps on pacing since
independence 1961 to date. Industrialization in Tanzania has a positive, though complex,
relationship with economic growth. In order to improve development of industries and country’s
economic growth towards achieving the TDV 2025, the challenges and constraints which hinders
industrial development should be evaded
Genetic variation and lack of hybridization in five cichlid fish species in the Malagarasi River basin, Tanzania
Journal ArticleAmong the most widely cultured groups of freshwater fish species are tilapiine cichlids. This has contributed to
introduction of cichlid fish species in area where they were not native. Consequently, has contributed to negative
ecological effects on local species and their habitats through competition, habitat alteration and loss of unique
population genetic structures due to hybridization. This research study aimed to assess the genetic status of five
cichlid fish species red listed by the International Union for Conservation of Nature (IUCN) as least concerned
species. A mitochondrial Cytochrome Oxidase Subunit I (COI) gene fragment from 112 individuals collected from
three sampling sites were used to determine the present genetic diversity of the cichlid species inhabit the
Malagarasi River system which discharge water into Lake Tanganyika. The highest nucleotide diversity (0.02 ±
0.01) and haplotype diversity (0.94 ± 0.04) were recorded from Haplochromis pharyngalis. The lowest levels of
nucleotide and haplotype diversity were recorded from Oreochromis leucostictus. The Analysis of Molecular
Variance (AMOVA) resulted into statistically significant genetic differences (Φst: 0.96, P < 0.001) among the
cichlid species studied. The minimum spanning haplotype network and maximum-likelihood phylogenetic an
alyses support the AMOVA findings as no species is sharing any haplotype with other species. The values of
neutrality tests suggested that the studied cichlid fish species are stable and not expanding. These findings
highlight the necessity of conservation interventions in the area especially for the species which displayed low
nucleotide and haplotype diversity
Agro-meteorological services in the era of climate change: a bibliometric review of research trends, knowledge gaps, and global collaboration
Journal ArticleIntroduction: Agro-meteorological services are crucial for mitigating climate
variability’s impact on agriculture and enhancing food security. Despite their
importance, the global research landscape in this field remains underexplored.
This study examines the evolution of agro meteorological research from 2010 to
2024, focusing on trends, contributors, and regional developments.
Methods: A bibliometric analysis was conducted using the Dimensions database,
with visualizations created via VOSviewer. The study analyzed publication trends,
key institutions, authors, journals, and subject clusters. Statistical correlations
assessed collaboration and institutional impact.
Results: The results revealed that publications increased steadily, peaking
in 2020 (r = 0.92, p < 0.01), reflecting emphasis on sustainability and climate
adaptation. Collaborative publications correlated strongly with institutional
impact (r = 0.75, p < 0.01), led by Wageningen University and the University
of Chinese Academy of Sciences. Sustainability and The Science of the Total
Environment were key journals. Sub- Saharan Africa and South Asia showed
significant research growth (r = 0.85, p < 0.01).
Discussion: The results highlight the field’s global, interdisciplinary scope and
rising contributions from developing regions. However, capacity gaps and
limited integration of indigenous knowledge persist. Inclusive partnerships and
capacity building are essential to strengthen agro meteorological services and
address climate challenges effectively
Revisiting chemical and microbiological quality and safety of fish and fish products
Journal ArticleFish and fishery products constitute a primary global food source, providing essential protein and nutrients. Ensuring their
safety and quality throughout the supply chain is paramount. The safety and quality of fish and fish products are paramount
considerations in the global food industry but their quality and safety may be compromised at various stages of transport,
handling, and processing. The major contaminants of fish and fish products are chemical and microbiological in nature.
Chemical contaminants commonly found in fish, including heavy metals, pesticides, and persistent organic pollutants which pose
significant risks to consumers. Microbiological contaminants are both pathogenic and spoilage microorganisms such as
Salmonella, Listeria monocytogenes, and Vibrio spp which are often implicated in foodborne illnesses associated with seafood
consumption. This review synthesizes current knowledge on the chemical and microbiological contaminants facing the fish
industry while advocating for enhanced regulatory frameworks and sustainable practices to ensure consumer safety as well as
modern methods for detecting these microorganisms, including molecular techniques like PCR (Polymerase Chain Reaction) and
biosensors that enhance detection sensitivity
