ABSTRACT

Cashew consumption has been increasing globally, but environmental issues through the whole cashew supply chain, from production, processing and transportation, have been raised. Thus, green supply chain redesign has been put forward but implementation of related practices faces many barriers. Using the case of the Africa cashew industry, which produces over half of global raw cashew nuts but only process less than 10% to kernel, this paper systematically identifies these barriers considering stakeholders through the whole cashew supply chain. Based on evaluation of four experts, results by grey Decision Making Trial and Evaluation Laboratory reveal that successful green supply chain redesign implementation needs two elementary efforts by kernel distributors. One is increased collaboration with multi-tier suppliers (producer organizations and processors) and the other is to get strategic support from industry bodies, non-governmental organizations and development agencies. Additionally, in the short-term, kernel distributors need to overcome three key operational barriers, lack of internal top-level management commitment, lack of integrated management information and traceability systems, and uncertainty of economic benefits. Furthermore, barriers such as difficulties to assess environmental sustainability performance and lack of consumer demand for green cashew should be addressed in the long-term. This study contributes to identify barriers to the successful implementation of green supply chain redesign from perspectives of both the focal enterprise and the whole supply chain. A robust multi-criteria decision making method further reveals the most important and fundamental barriers which can offer decision support for kernel distributors and policymakers in the cashew industry.

Conclusions

Due to the impact on the environment, especially in regards to climate change, there has been critical pressure on focal enterprises to enhance the environmental sustainability performance in supply chains (Walker et al., 2008; Zhu and Sarkis, 2007). GSCR brings an opportunity for focal enterprises, particularly in agrifood supply chains to address environmental sustainability concerns (Iakovou et al., 2014). However, barriers to GSCR exist in many industries. In this study, guided by two objectives highlighted in the first section, we systematically identified numerous barriers to GSCR and implementation of related practices in the West Africa cashew industry. These barriers are based on both operational and strategic perspectives of the supply chain. The operational barriers are related to the role of a kernel distributor as the focal enterprise of the cashew supply chain and the role of other internal supply chain actors. The strategic barriers are related to the role of external actors in the supply chain environment. Subsequently, based on data from two top-level managers of kernel distribution enterprises and two cashew supply chain experts, the relationships among the identified barriers were analyzed with the aid of the grey-based DEMATEL method. The results of analysis provide decision support for kernel distributors and policymakers in the cashew industry to develop effective approaches for GSCR and the implementation of related practices. The results of the study show that the highest prominence barriers are fairly spread across the various actors of the supply chain. As such, overcoming the numerous barriers to GSCR and implementation of related practices in the West Africa cashew industry strongly rest on the role of both internal and external actors of the supply chain. Therefore, kernel distributors need to strengthen their collaboration with multitier suppliers in the operation of West Africa cashew supply chains. Also, the strategic support from industry bodies, NGOs and development agencies is crucial for successful GSCR implementation. In the short-term, government policies and regulations should support kernel distributors to overcome three key operational barriers which are lack of top-level management commitment, lack of integrated management information and traceability systems and the uncertainty of economic benefits for GSCR and implementation of related practices.
