Lack of good post‐harvest storage of cocoa pods has been responsible for the low commercial quality of cocoa beans. This study aims to evaluate the effect of modified packaging and storage time of cocoa pods on the corresponding commercial qualities of cocoa beans.

Preweighed cocoa pods obtained from the experimental station of the Cocoa Research Institute of Nigeria, Ibadan, Nigeria were stored under three modified packaging conditions, namely: black non transparent polythene film (B_NTPEF), transparent polythene film (T_PEF) and N_A (normal atmosphere environment).

The study found that there was a rise in the mean temperatures of samples in all the storage environments up to the 12th day of storage, after which the mean temperature declined until the end of the storage period. Cocoa butter fat, bean weights, severity of decay and mould growths depended on the type of packaging and storage time.

At p<0.05 the use of modified packaging of cocoa pods significantly affects the commercial values of the beans. The best of these qualities was conserved in the T_PEF.

This paper aims to assess how cocoa supply chain companies disclose sustainable development goals (SDGs) information in their sustainability reports. This assessment highlights strategic aspects of sustainable supply chain management and reveals leveraging sustainability points in the cocoa industry.

The two-step qualitative approach relies on text-mining company reports and subsequent content analysis that identifies the topics disclosed and relates them to SDG targets.

This study distinguishes 18 SDG targets connected to cocoa traders and 30 SDG targets to chocolate manufacturers. The following topics represent the main nexuses of connections: decent labour promotion and gender equity (social), empowering local communities and supply chain monitoring (economic) and agroforestry and climate action (environmental).

By highlighting the interconnections between the SDGs targeted by companies in the cocoa supply chain, this paper sheds light on the strategic SDGs for this industry and their relationships, which can help to improve sustainability disclosure and transparency. One interesting input for companies is the improvement of climate crisis prevention, focusing on non-renewable sources minimisation, carbon footprint and clear indicators of ecologic materiality.

This study contributes to policymakers to enhance governance and accountability of global supply chains that are submitted to different regulation regimes.

To the best of the authors’ knowledge, no previous study has framed the cocoa industry from a broader SDG perspective. The interconnections identified reveal the key goals of the cocoa supply chain and point to strategic sustainability choices for companies in an important global industry.

Various models and approaches are implemented to provide technical assistance and support to improve cocoa farmers' welfare in Ghana. The Farmer Business School (FBS), which is analogous to Farmer Field School (FFS), is one of the few initiatives of GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit) and Ghana Cocoa Board (COCOBOD). The main aim of the initiative is to train smallholder cocoa farmers to perceive cocoa production as a business. However, there is limited or conflicting evidence as to the effect of FBS on productivity and food security, especially in Ghana. This study assessed FBS participation and the participation's impact on productivity and food security of cocoa farmers.

The study used primary data collected from 542 cocoa farmers in Central and Western North regions of Ghana and employed descriptive statistics, perception index and Endogenous Switching Regression (ESR) as analytical tools.

The results, which reported an overall perception index of 0.7, indicated that the farmers had a strong positive perception on the FBS program. The results also showed that sex of a farmer, number of years of formal education, farm size, extension contact, perception, distance to extension outlet and membership of farmer-based organizations (FBOs) significantly influenced the decision to participate in FBS program. Also off-farm income, years of education and household size significantly influenced farm productivity and household food security. The results further showed that participation in FBS improved productivity and food security of cocoa farmers.

The study used data from two regions of Ghana, namely the Central region and the Western North region. Findings from studies using data covering all cocoa growing areas of Ghana could be more informative in formulating policies aimed at encouraging participation in FBS and consequently help improve cocoa productivity and food security.

This article offers insights into the welfare effects of FBS on cocoa farmers as previous similar studies are without this information.

The study examines the marketing of cocoa in Nigeria as a pilot study to formulating new strategies for the marketing of agricultural commodities. Three interrelated and interdependent approaches have been developed namely, institutional, functional and market structure strategies. These reveal how exchange, physical and facilitating functions can be effectively utilised to expedite the distribution of cocoa through the marketing system. However, methods in use by the cocoa farmers are not efficient due to problems of shortages and the policies of the Marketing Boards and the commodity boards. Improved methods of cocoa cultivation and the removal of impediments on granting credit facilities are recommended.

The purpose of this paper is to examine the macro-, meso- and micro-level approaches to building sustainability in Ghana's timber, cocoa and goldmining industries s Ghana works to align sustainability efforts with the sustainable development goals proposed by the United Nations.

Using qualitative content analysis, a synthesis of contemporary literature on Ghana's timber, cocoa and gold mining industries was conducted to provide a descriptive evaluation of sustainability efforts in those industries.

At the macro-level, Ghana continues to invest in infrastructure, privatize industries and develop an urban development agenda to encourage foreign direct investment (FDI); improved forest management and green building policies and reduction of galamsey are also implemented. At the meso-level, the timber industry encourages land reclamation and green building technologies; the cocoa industry works to replenish lost trees, develop supply-chain partnerships, and encourage certifications; the goldmining industry works to regulate informal mining and reduce galamsey and the use of toxins in exploration. At the micro-level, alignment has developed between the micro- and meso-levels in the timber and cocoa industries, whereas micro-level players in the timber industry are less successful, given its large, unregulated informal sector.

Existing literature is missing discussion on the alignment of macro-, meso- and micro-level approaches to sustainability in Ghana's timber, cocoa and gold mining industries with attention to the United Nations' Sustainable Development Goals as the premise for the work.

The purpose of this paper is to provide ethnographic data on the lives of children working in cocoa‐producing communities in Ghana and to illustrate the importance of contextualisation in understanding the phenomenon of child labour.

The paper is based on anthropological fieldwork carried out in Ghana using participant observation and child‐focused participatory research methods. It also includes an analysis of media sources and policy documents.

It shows that the children involved in this study worked freely and willingly on family cocoa farms. It also shows that research and interventions must be context‐based and child‐centred as forms of child labour in cocoa are not uniform across West Africa.

Unfortunately, the scope of the paper does not allow for a discussion of recent interventions and progress relating to child labour in the West African cocoa industry.

This paper challenges many of the assumptions made about child labour in cocoa and offers new insights into the lives of children in these communities.

The purpose of this paper is to examine the significance of the direct and indirect effects (through country and firm’s specific advantages) of government policies for export promotion (GPEP) on the export performance of small and medium-size enterprise (SME) Cocoa exporters in Cameroon.

To test the proposed model, data were obtained through self-administered questionnaires using snowball sampling technique to 101 SME Cocoa exporters. This was analyzed using structural equation modeling (SEM) techniques to examine both the direct and indirect effects of GPEP on the export performance of SME Cocoa exporters in the South and Centre Regions of Cameroon.

The findings suggest that GPEP had both direct and indirect effects on the export performance of SME Cocoa exporters. Direct effect was on the usage of GPEP which reduces operating cost and increase performance. The indirect effects were through the provision of country and firms specific advantages. However, the only significant path was through the provision of export marketing information.

The research is limited to one country, one sector, and two regions and does not take into consideration other factors that may influence the effect of GPEP, country, and firms specific advantages on export performance. Moreover, the non-significant paths should be interpreted with caution and further testing required in a different context.

Empirical findings are relevant for the government and SME Cocoa exporters. It informs the government about the effectiveness of GPEP and the need to disseminate marketing information using every possible medium best understood by the SMEs. It suggests an opportunity for engagement of both SMEs and government authorities in accessing the outcome of GPEP which will increase transparency, awareness, usage, and export performance.

The research has successfully developed and tested a model for analyzing the direct and indirect effects of GPEP on export performance based on the resource-based view and SEM in a context where there is a call for more empirical and theoretical work on export performance due to limited studies. The framework reveals positive effects of GPEP, country, and firms’ specific advantages as determinants of export performance.

This paper aims to derive the time-varying relative export competitiveness (REC) of the Nigerian cocoa sector against Nigeria’s share of world agricultural exports (REC_WA) and world merchandise exports (REC_WM) from 1995 to 2018. By concentrating on different factors such as demand and supply capacity, price factors and exchange rate, the authors examine the determinants of REC.

The authors calculated three different REC indexes. The authors also developed the relative symmetric export competitiveness index for comparative advantage calculation and avoiding the possible bias. The determinants of REC for Nigerian cocoa were captured using the short-run regression (SRR) model.

The study showed that Nigeria’s cocoa exports are still competitive despite experiencing some declining stages. Based on the SRR model, higher per capita income had a positive effect on the REC, while higher domestic prices significantly reduced the REC of cocoa. Further, the African Growth Opportunity Act agreement adversely affected the REC of cocoa.

This study provides a foundation for future research and enhances the literature on agricultural trade. This research makes a few contributions both from a scientific and a policy perspective. First, it is the first study on the REC analysis for the Nigerian cocoa industry. Second, a wide range of comparisons of REC among the world’s largest cocoa exporters was provided following implications of the various economic policies and local policy strategies. Third, the latest 24-year data sets were covered.

Change in the economic status of a low-income country is accompanied by an expected increase in investment and economic activities along with land degradation and biodiversity loss. This study aims to explore Ghana's transition from a low-income to a lower-middle income economy, and the impact of the accompanying rise in extractive activities on the upstream cocoa supply chain (CSC) and its supporting ecosystem.

The author conducted interviews and made critical observations on Ghana's upstream CSC. Grounded theory (GT) and system dynamics (SD) methodologies were employed to extract and analyze themes from the data gathered. Causal loop diagrams were derived from the analyzed data to provide insight into the possible long-term structural behavior of the upstream CSC due to the change in Ghana's economic status.

The findings suggest that continuous increase in land capture by open-cast mining and logging concessionaires, poor environmental law enforcement and farmer discontentment could cause a decline in cocoa production and biodiversity.

This research could stimulate the identification of a most effective alternative policy (such as agroecological farming) to improve the living standards of upstream CSC partners and reduce biodiversity loss. The models herein could serve as a learning/demonstration tool for researchers, academia and policymakers when brainstorming students, or during stakeholder (community/society) engagement/consultation sessions, to discuss policy decisions and their consequences. The model approach could also be helpful when designing strategic land-use policies. This could improve understanding of the complex interdependent relationships and the consequences of land degradation, loss of biodiversity and rural livelihood from a system thinking perspective.

The study aimed at examining the current and future impact of climate change on cocoa production in West Africa.

A translog production function based on crop yield response framework was used. A panel model was estimated using data drawn from cocoa-producing countries in West Africa. An in-sample simulation was used to determine the predictive power of the model. In addition, an out-sample simulation revealed the effect of future trends of temperature and precipitation on cocoa output.

Temperature and precipitation play a considerable role in cocoa production in West Africa. It was established that extreme temperature adversely affected cocoa output in the sub-region. Furthermore, increasing temperature and declining precipitation trends will reduce cocoa output in the future.

An important implication of this study is the recognition that lagging effects are the determinants of cocoa output and not coincident effects. This finds support from the agronomic point of view considering the gestation period of the cocoa crop.

Although several studies have been carried out in this area, this study modeled and estimated the interacting effects of factors that influence cocoa production. This is closer to reality, as climatic factors and agricultural inputs combine to yield output.
