Emphasis on the potential roles diverse farm production systems could play in enhancing food consumption variety and nutritional well-being in rural developing countries has increased in recent times. However, there are paucities of empirical works connecting diversity in agricultural production and dietary diversity in Africa, and Nigeria in particular. The purpose of this paper is to, therefore, examine, among others, the causal link between farm production diversity and consumption of varied diets among farm households in Nigeria using a nationally representative panel data.

Unlike the simple food count measure, the authors adopt two-dimensional indices to assess food diversity, and estimated both fixed and random effects versions of panel data econometrics models with the two-dimensional indices as regressands.

Results show that food production system is less diverse with an average farm household consuming fairly varied foods across seasons. All the econometrics models estimated consistently established positive and statistically significant influence of farm production diversity on household dietary diversity. Higher food prices, especially rice and roots and tubers could substantially reduce dietary diversity with the negative effects likely to be more devastating for low-income farm households. The specificity of household being a net food seller had positive, although weak influence on dietary diversity.

The findings accentuate, among others, the need for strategies to promote farm production diversity, transform farm households to net-sellers of foods and enable them take advantage of food price signals to boost farm incomes as important pathway for diet quality improvement and reduction of food insecurity, malnutrition and related diseases in rural Nigeria

This study assessed the extent of women empowerment and empirically investigated its effect on the adoption of climate-smart agricultural practices at the plot level in Nigeria.

Using the empowerment score and women empowerment gap for each household which were derived from the Abbreviated Women's Empowerment in Agriculture Index, a multivariate probit model which controlled for the influence of gender and women empowerment on climate-smart agricultural practices' adoption was estimated. The study made use of data from the ECOWAS-RAAF-PASANAO survey conducted in Nigeria in 2017.

The results show that men are significantly more empowered than women in four out of the five domains of empowerment and are more likely to adopt crop rotation. However, female plot managers have a higher likelihood of adopting green manure and agroforestry, while no significant gender differences in the adoption of organic manure and zero/minimum tillage were found.

The results suggest that closing the empowerment gap between women and their spouses would positively influence the adoption of agroforestry.

This study represents the first attempt to examine the adoption of these practices from a gender perspective using a nationally representative plot-level dataset in Nigeria. Furthermore, this study contributes to existing literature on how gender differences influence technology adoption by modelling the effect of empowerment score for each plot manager, and the women empowerment gap for each household on the adoption of five climate-smart agricultural practices.

The purpose of this paper is to investigate urban tree forest utilisation and management through application of contingency valuation approach in Ogun State, Nigeria.

A total of 120 respondents residing in Abeokuta Metropolis were randomly sampled. Data collected were analysed using descriptive statistics, probit and Tobit regression analyses.

Results revealed that respondents demonstrated willingness to pay (WTP) monthly for management of urban trees. Larger percentage (94.0 per cent) of the respondents benefited from shade, 48.0 per cent benefited from reduction of pollution while 76.7 per cent benefited from prevention from harsh weather. Results of probit analysis revealed lower probability of WTP for urban tree management among older respondents ( p<0.1); while females respondents had a higher probability of payment for tree management ( p<0.05). In the same vein, younger respondents (p<0.05) as well as higher income earners ( p<0.01) exhibited more WTP for urban trees management.

The study concluded that trees were an invaluable environmental asset among urban households, while the households also demonstrated strong willingness to manage and sustain their uses.

Older respondents need to be further enlightened on sustainable management of urban trees for environmental stabilisation and provision of aesthetic benefits.

This paper introduces an innovative technique to the valuation of urban tree and brought to the fore, importance attached to trees as a non-market environmental commodity.

The economic importance of palm oil produced by its producers in food requirement, income generation, production and consumption has led to a significant increase in its demand over the years. Thus, this chapter evaluates the effects of palm oil price fluctuations on the welfare of palm oil producers in Nigeria based on annual time series data (1980–2018). In achieving its objectives, the study employs Autoregressive distributed lag model (ARDL). The result establishes the presence of a long-run relationship in the welfare of palm oil producers. The long-run estimates show that palm oil prices had a positive but insignificant relationship with the welfare of palm oil producers. In the short-run estimates, palm oil price and the exchange rate had adverse and significant effects on the welfare of palm oil producers, while the inflation rate positively and significantly influenced welfare. Therefore, the welfare programme should adopt policies that will stabilise the palm oil price and other foodstuffs to increase the standard of living of palm oil producers and raise their literacy levels.

Although African markets have incorporated various selling practices originating from the West, there are still some selling practices that are indigenous to the African people and are widely practised by sellers across the continent. This chapter is an attempt at documenting those indigenous practices with the aim of providing managers, educators and policymakers of the continent with a reference document on what these indigenous selling practices are, how sellers invoke them in the course of transactions and the cultural values that guide these practices. Primary data were gathered from three countries representing western, eastern and southern Africa through observations, field surveys and in-depth and key informant interviews while literature was sourced for secondary data. The chapter identified street selling, haggling and credit-based selling as the major indigenous selling practices found among sellers in Africa. The cultural values that guide selling in the continent include respect, trustworthiness and kindness. The chapter displayed a framework to explain the subject matter and made some practical suggestions that are relevant for managers, educators and policymakers.

This study aims to assess the factors influencing the effective implementation of extended producer responsibility (EPR) practices within the context of sustainable accounting goals and circular economy principles. It seeks to provide insights into the significance of EPR policies for manufacturing industries striving to enhance their environmental, social and governance performance while ensuring sustainable accounting of their business operations.

The methodology proposed in this article is based on the decision-making trial and evaluation laboratory (DEMATEL) technique. This approach formulates a structural framework for evaluating influential elements among critical recognized factors. By using DEMATEL, the study examines the interconnectedness between assessed factors through a cause-and-effect diagram, facilitating the integration of EPR into sustainable accounting practices.

The research findings reveal that the most impactful contributors to sustainable accounting practices of EPR within the framework of sustainable development goals and circular economy are producers, consumers, eco-design, public awareness and the support of local authorities. These findings underscore the importance of considering these factors in implementing EPR and advancing sustainable accounting practices.

This paper contributes to the literature by proposing a DEMATEL-based model for evaluating the factors affecting the implementation of EPR within the context of sustainable accounting goals and circular economy principles.

Cassava is a starchy crop with several industrial applications, but it deteriorates very fast after harvest. Refrigeration has been used to extend the storage life of the root and the starch isolated from the stored roots characterized. Hence, the purpose of this research is to investigate the chemical, functional, pasting and sensory properties of custard prepared from starch isolated from refrigerated cassava root.

Freshly harvest cassava root were cleaned and stored in a refrigerator operating at 4 °C for a period of one, two and three weeks. Starch was extracted from the fresh and stored roots using established method and custard prepared from each of the starch sample. The custard sample was analysed for amylose content, functional, pasting and sensory properties.

Amylose content in the pastes varied significantly from 18.45 to 25.45%. Refrigeration showed a significant impact on the swelling power of the custard, which could be linked to variation in amylose content. Colour and textural properties of the custard were similar across the samples suggesting a minimal impact of refrigeration on the isolated starch. Refrigerated cassava roots can produce acceptable custard with minimal changes in sensory properties if the storage period is closely monitored.

In a previous study, the authors have shown that starch and cooked paste may be made from stored cassava roots without substantial changes in the quality of these products. This study further confirms the possibility of using starch from the stored roots in food applications such as in custard formulation. No report has documented the properties of custard from starch obtained from refrigerated cassava root.

This study was aimed to develop and evaluate nutritional efficacy and bio-efficacy of food products from plantain, soycake, rice-bran and oat-bran flour.

The flour samples were blended as follows: plantain 70% and soycake 30% (PS); plantain 65%, soycake 30% and rice bran 5% (PSR); plantain 65%, soycake 30% and oat bran 5% (PSO); and plantain 60%, soycake 30%, rice bran 5% and oat bran 5% (PSRO). Antioxidant and nutritional properties of the blended foods and controls (100% plantain and Cerolina) were determined.

Protein (16.2–19.4 g/100g) and biological values (98.5–99.3%) of the food samples were significantly (p = 0.03) higher than 100% plantain (5 g/100g, 31.6%) and Cerolina (17.9 g/100g, 98.3%). Pack cell volume (36.2–42%), serum protein (7.3–9.3 mg/dL), urea/creatinine (1.1–2.8) and aspartate-aminotransferase/alanine-aminotransferase ratio (0.9–1) of the foods were significantly (p = 0.03, 0.01, 0.02 and <0.01, respectively) higher than 100% plantain (28%, 1.6 mg/dL, 4.6 and 0.8) and Cerolina (46%, 4.9 mg/dL, 3 and 0.73). In vivo antioxidant activity of the food samples decreased from PSRO to PSO, PSR and PS, respectively and were higher than control samples. Nutritional performance of formulated foods in rats was similar to that of Cerolina, but higher than in 100% plantain. Cerolina and 100% plantain were rated higher in overall acceptability than formulated foods; however, PSO was most preferred followed by PSRO for the formulated foods.

The study established that PSRO was rated best in terms of nutrition, growth performance and antioxidant activities. Hence, this food may be suitable as functional food to prevent malnutrition and oxidative stress.

This study aims to investigate the facilitating conditions (FCs) and how these FC affect institutional repository (IR) sustainability practices in public universities in Nigeria.

A survey research design was adopted in this study. The study population comprised 542 librarians from public universities that have IRs across Nigeria. A sample size of 230 librarians was determined using Taro Yamane’s formula. A multi-stage sampling technique was used to select the respondents in three stages, which were purposive, stratified and purposive sampling. A structured, validated questionnaire was used for data collection. Data were analyzed using descriptive and inferential (simple and multiple regression) statistics at a 5% level of significance.

The result revealed that the availability of FCs (ßeta = 0.459, t(211) = 7.719, p = 0.000) has a positive and significant influence on IR sustainability in public university libraries in Nigeria. The F-test (1, 223) value of 59.582 shows that there is sufficient evidence to substantiate the model’s usefulness in explaining IR sustainability. The R² (0.211) indicates that 21.1% of the variation in IR sustainability is explained by the availability of FCs in public university libraries in Nigeria. The finding suggests that the availability of FCs is a vital predictor of IR sustainability in public university libraries in Nigeria. The result also depicts that out of the eight parameters that measure the availability of FCs, it was current awareness of IR that had a positive and significant influence on IR sustainability.

This study concluded that ICT skills and FCs are contributory factors to IR sustainability practices by librarians in public university libraries in Nigeria. It was recommended that university administrators formulate policies that promote the sustainability of IR and provide adequate funds to support IR sustainability. Furthermore, the library management in public university libraries in Nigeria should drive content recruitment and create awareness of the IRs among students and faculty to ensure continued use.

This study aims to investigate the adoption and use of electronic voting (e-voting) system as an option to credible elections in Nigeria, as well as the factors that could influence the readiness of Oyo state citizens in Nigeria to use the system.

The study adopts the survey research design, while the Technology Readiness Acceptance Model provides the theoretical framework. A two-stage sampling procedure (random and convenience) was used to select 500 Nigerian citizens, who are of voting age, while data were collected with a structured questionnaire.

Findings reveal that the citizens are ready to use the e-voting system if adopted by the Nigerian Government. Optimism and innovativeness are positively correlated, and perceived discomfort and perceived insecurity are negatively correlated, with readiness to use e-voting system by Oyo state citizens. The Technology Acceptance Model constructs (perceived usefulness and perceived ease of use), as well as computer self-efficacy also have positive correlations with readiness to use of e-voting.

The population of the study was limited to only citizens in one state of the federation; hence, the results cannot be generalised to all citizens in Nigeria.

The study contributes to existing knowledge on adoption and use of technology and confirms that optimism and innovativeness are motivators and discomfort and insecurity are inhibitors of intention to use and actual usage of technology. Hence, these constructs should be taken into account and promoted when Nigeria is planning to adopt the e-voting system.

This paper could assist the Nigerian Government on the factors to consider when implementing the e-voting system.

This paper is one of the first pieces of empirical research that attempted to investigate the factors that could promote acceptance and use of the e-voting system in Nigeria.
