This study analyses income inequality and distribution patterns among key actors in the cassava value chain. The study also identifies factors that influence profit of key actors in the cassava value chain.

The study was conducted in Oyo State, Nigeria, using primary data from 620 actors, consisting of 400 farmers, 120 processors and 100 traders in the cassava value chain. The Gini coefficient was used to estimate income inequalities within and between actors. Multiple linear regression was applied to identify factors that influence the profit of the actors in the cassava value chain.

The result shows a gender pattern in the participation in the cassava value chain: men dominate in the production, whereas women mostly engage in processing and marketing of processed cassava products. We also find that incomes are unequally distributed among actors, favouring traders and processors more than farmers in the value chain. Women are better off in processing and trading of value-added products than in the raw cassava production. Spatial differences also contribute to income inequality among farmers in the cassava value chain. An increase in farmers and processors’ incomes reduces inequality in the value chain while an increase in traders’ income widens inequality. Age is significantly negatively correlated with actors’ profit at 1%, while educational level significantly increases their profit at 5%. Processors and traders with large households have a higher profit. We also find that farm size, experience and labour input have significant positive effects on farmers’ profit only at 5%. Membership in an association increases farmers and processors’ profit at 1 and 10%, respectively.

The study recommends that agricultural policies that promote agrifood value chains should aim at minimizing income inequality by targeting vulnerable groups, particularly female farmers to achieve sustainable development in rural communities.

Existing studies recognise income inequality in agricultural value chains in sub-Saharan Africa. However, there are few rigorous quantitative studies that address this pressing issue. Our paper fills this knowledge gap and suggests ways to minimise income inequality in the agri-food value chain, using the example of the cassava value chain in Nigeria.

The purpose of this paper is to analyse the effects of the determinants of farmer participation in value addition through cassava processing in Nigeria.

This study employs the probit model to analyse the determinants of farmer participation in value addition whereas the Tobit model is used to investigate the determinants of the extent of producer’s involvement in value addition using a data set of 400 cassava farmers drawn from the Oyo State of Nigeria.

The findings further indicate that among other factors, human capital factors including farmer age and location variable tend to reduce farmer participation in value addition through processing whereas experience and record keeping promote farmer participation in cassava processing. Institutional variables, notably membership of farmer association, extension access and credit access, enhance farmer participation in value addition. Finally, ownership of a radio set, a television set and access to electricity strengthen the value-adding capacity of farmers.

This study only considers the determinants of producers’ participation in cassava processing but does not explicitly analyse the impact of value addition on their profit margin. This issue would form a basis for future research to enhance knowledge in the extant literature.

The study suggests that if the value-adding capacity of farmers is strengthened, rural economy is likely to be improved upon through the proliferation of rural food processing enterprises.

Despite the relevance of developing food value chains in Africa and integrating farmers in them, there are limited studies on promoting value addition among farmers. This study contributes to narrowing this knowledge gap.

The purpose of this paper is to evaluate consumers’ willingness to pay (WTP) for composite flour bread produced with a blend of 15-40 per cent cassava flour blended with wheat flour in Ghana.

The analysis is based on interviews with 350 consumers in the Ashanti and Eastern Regions of Ghana to assess their awareness, perceptions and WTP for cassava-wheat composite bread. From these consumer interviews, a hedonic regression model was applied to evaluate consumers’ WTP for various attributes of composite flour bread. Price-related and health-related perceptions of consumers on cassava-wheat composite bread were investigated with perception indices. Multi-attribute preference-based contingent ratings that rate product attributes in terms of importance to consumers was employed. The implicit prices of the product attributes representing the contribution of the product attributes to the WTP amount were also computed.

The paper finds that consumers who are aware of cassava-blended flour bread and who like its taste and texture are willing to pay more than consumers who are unaware. This leads to a policy recommendation advocating increased advertising of the economic and nutritional benefits of cassava-wheat blended composite flour bread.

Future studies should explore the choice experiments to examine preferences for the food product.

This paper evaluates consumers’ WTP for composite flour bread produced with a blend of 15-40 per cent cassava flour and wheat flour. Given widespread reliance on imported wheat flour and the simultaneously large volumes of locally available cassava, it is important to consider opportunities for import substitution (and possible cost reduction for consumers) of blended flour products such as cassava-wheat composite flours. Nigeria has imposed a 10 per cent blending requirement for this reason. Ghana has taken important measures recently for the development of high-quality cassava flour, and so research on its potential and actual uptake is welcomed and highly relevant to food security and agribusiness development.

This study aims to assess gender-based differences on farmers’ perception of impacts and vulnerability to climate change and the implementation of adaptation strategies in the Pra River Basin of Ghana, while also providing lessons for other Sub-Saharan nations and regions with similar conditions.

The study used semi-structured interviews and questionnaires to collect data from 344 farmers, 64 participants in focus group discussions and 6 agriculture extension officers (key informants) from 10 districts in the Pra River Basin of Ghana.

Results showed several differences in how climate change is perceived and tackled by male and female genders. In the perception of male farmers, for example, they were found to be more vulnerable to increased temperature, and changes in rainfall and growing season, whereas female farmers on average were considered to be less resilient to floods and droughts for different reasons. Moreover, floods posed higher risks to farming than other climate change impacts. Gender roles had a significant correlation with the type of adaptation strategies practised. Men adopted agrochemicals more often than women, as an adaptation strategy.

Gender-differentiated interventions should be incorporated in the national climate change action plan for sustainable development in a rain-fed agricultural economy such as Ghana. The study recommends several actions to promote gender equity in the assessed region.

This research assessed the gender differentials in climate trends, impact, vulnerability and adaptation based on primary data collected between April and May 2019 and compared the results with climate data in the basin for the period 1991–2014. It is an empirical study focused on primary data analysis obtained in loco by authors, involving approximately 400 participants.

The purpose of this paper was to determine the effect of route optimization on travel distance, travel time and fuel consumption of municipal solid waste (MSW) collection trucks.

The study modeled the existing waste collection routes in three local authorities in Ghana and proposed optimal routes using Esri’s ArcGIS Network Analyst Extension. The system generated optimal distances and times were validated by subjecting collection trucks to the optimal routes. Paired sample t-test was used to analyze the differences in means of the existing and optimal outcomes. The collected data were subjected to correlation and uncertainty analyses.

Results from the study indicated that weekly travel distance reduced by 81.27 km, translating into saving of 4.79 percent when trucks used the optimal routes. Travel time and fuel consumption reduced by 853.59 min and 145.86 L, making savings of 14.21 and 10.81 percent, respectively. Significant differences occurred between the means of the existing and optimal routes for travel time and fuel consumption, for each of the three local authorities.

The study was conducted in Ghana using data collected from three local authorities.

Significant reduction of MSW collection cost can be achieved by waste management practitioners through route optimization.

The effect of route optimization on travel distance, travel time and fuel consumption has been established. Statistical analyses of the existing and optimal outcomes of the three local authorities have been provided. The findings from this study support the hypothesis that optimal routes reduce operating cost through savings in travel distance, travel time and fuel consumption.

The purpose of this paper is to find out and document what reforms have taken place in the institutional structure for solid waste management (SWM) in Kumasi since the inception of a National Environmental Sanitation Policy (NESP) in Ghana in 1999, and what impact institutional reforms have made on solid waste collection service efficiency.

The study undertook a before‐and‐after assessment of key institutional issues as well as service efficiency within five years of the inception of the policy using questionnaires and interviews to collect data and information from relevant SWM stakeholders in the metropolis.

It was found that the implementation of the policy has led to changes in the organisational structure for SWM in the city with the introduction of private sector participation, which has led to improvement in efficiency in terms of service coverage and cost recovery. Service coverage increased from about 50 per cent in 1999 to an annual average of 87.4 per cent between 2000 and 2004, while the amount recovered through house‐to‐house collection services increased from 26.5 per cent of the WMD's expenditure in 2001 to 68.6 per cent in 2004.

The findings and recommendations can inform future SWM policy reviews and implementation in the city and elsewhere.

The study is the first attempt at documenting the historical evolution towards the current institutional structure and a scientific assessment of the impact of the reforms on service efficiency in Ghana.

In Ghana, the practice of landlords demanding that renters pay rent advance (RA) of between six months and five years is well noted. Surprisingly, renters appear divided into the benefits and drawbacks of the rent advance payment. Ahead of the 2020 general elections, the two leading political parties in Ghana promised to establish a rent assistance scheme to help renters working in the formal and informal sectors and earning regular incomes to pay their RA. This paper aims to scrutinize the differences in the demographic, employment and housing characteristics between the critics and non-critics of the RA payment in Ghana and the factors that predict the likelihood of being a critic of the RA system.

The study is exploratory and draws empirical data from surveys administered to 327 graduate renters from 13 regions in Ghana. It uses non-parametric and parametric tests, namely, Chi-square goodness-of-fit and T-test to explore these differences between both critics and non-critics of the RA.

There are statistically significant differences between critics and non-critics in terms of the association between their educational attainment on the one hand and their marital status, employment status and employment sector on the other hand. The research also reveals that monthly expenditures, number of bedrooms and RA period significantly predict the likelihood of being a critic of the RA payment or otherwise.

The study provides evidence which policymakers can draw upon to inform housing policy.

The study is the first to study the housing characteristics of graduate renters and to quantitatively distinguish between critics and non-critics of RA payment in Ghana.

Apprenticeship programmes are designed to provide young trainees with essential broad-based skills. Through apprenticeships, different sectors that are underpopulated can fill up their skills gaps. Apprenticeships are particularly useful to the construction sector which has a high ageing workforce and associated lower labour productivity. However, the completion rates of apprenticeship training programmes in the construction sector remain low in several countries across the globe. Thus, the purpose of this paper is to review the published research on apprenticeship training that is specifically focused on the construction sector, to determine the current status quo and suggest a direction for future research.

A systematic review approach was adopted. Based on a comprehensive search using SCOPUS databases, 33 relevant journal articles were identified and analysed.

It was found that monitoring and control is the most mentioned factor responsible for improvements in the completion rates of apprenticeship training. In contrast, the length of time required for going through the full training is the most common factor responsible for low completion rates. Three research gaps were identified, among which is the dearth of studies that has focused on apprentices training in developing countries.

The gaps identified in the current knowledge on apprenticeship training would serve as a justification for future investigations. However, the scope of the review is limited to papers published in academic journals and citable through SCOPUS.

The outcomes of the study provide researchers and other relevant stakeholders with a concise report on the findings of previous studies. It also provides insight into strategies for improving the completion rates of apprenticeship training in the construction sector.

A systematic evaluation of the extant literature draws on theoretical evidence and highlights the factors that are more likely to influence the outcomes of apprentice training for craftspeople in the construction sector.

The objective of this paper is to evaluate the learning gap between private and public school children in primary school, and ascertain the part of the private–public school learning gap that is due to differences in observables and the part that can be attributed to private school effect.

The paper utilized a household survey data from Ghana that assessed children on numeracy and literacy in both English and local languages. The primary methodology for this study is non-linear Oaxaca decomposition. The study also utilized Welch's t-statistics to test if there are any differences in the private–public school learning gaps across several sub-groups.

Findings from this study show a substantial gain for private school attendance on both numeracy and literacy. The results show that a little over 60% of the total learning gap in numeracy and literacy in English is explained by observable characteristics. However, observable characteristics almost explain all the learning gaps in the reading and writing of local languages. Evidence from the study suggests that the private school effect is homogeneous across several sub-groups. The results reveal years of education, expenditure on extra classes, religion and urbanicity as the most important variables explaining the gap that is caused by differences in observables.

Despite the belief that private school children in Ghana have better learning outcomes, there has not been any study to quantify this learning gap in the country and this study fills this gap. While there is literature on the differences in the learning outcomes between public and private schools, those studies have focused on the differences that are attributable to the private school effect. This article does not only present the differences in the learning outcomes but also shows the proportion that is due to observable characteristics and the part that can be attributed to the private school effect.

Aquaculture insurance has the potential of redressing climate-change because it serves as an alternative source of finance in the event of unforeseen circumstances. To this end, the authors examine the prospects, determinants and profitability of aquaculture insurance among fish farmers in the Eastern region of Ghana.

A total of 140 fish farmers were sampled for the study. Thematic analysis was used to determine perceived aquaculture insurance prospects. The Heckman's two-stage model, profitability index (PI) and return on investment (ROI) was employed to respectively determine the factors influencing aquaculture insurance participation and amount intensity and the profitability of aquaculture.

The thematic analysis revealed three themes on the perception of aquaculture insurance prospects: loss recovery, farm renovation and promotes agriculture. Different sets of demographic and institutional factors have varying influences on aquaculture insurance participation and amount intensity. Profitability index (PI) and return on investment (ROI) were respectively 2.07 and 3.2%.

The research provides relevant information on perceived aquaculture insurance prospects, aquaculture insurance participation, and amount intensity and profitability of aquaculture which can contribute to enhancing aquaculture insurance and the aquaculture industry in Ghana.
