Item Blockchain based solution for Sri Lankan agricultural supply chain to ensure food security(Research Symposium on Pure and Applied Sciences, 2018 Faculty of Science, University of Kelaniya, Sri Lanka, 2018) Basnayake, B. M. A. L.; Rajapakse, R. A. C. P.Low quality agricultural products are added to the market daily. Overuse of chemicals in the production process, using uncertified chemicals and mechanisms for preservation and ripening processes, are the major issues with an impact on agricultural product’s quality as well as overall health of the consumers. Mechanisms for identifying the quality of the agricultural products are highly demanded due to the lack of transparency in the current process. A crowd-based decentralized certification system is required instead of a central authority to certify the products. Blockchain technology is emerging as a decentralized and secure infrastructure which can replace involvement of a third party to verify the transactions within the system. The purpose of the research is to implement a blockchain based solution to verify the food quality and the origin of the agricultural supply chain. The data on the transactions, existing certification process, actors and their roles within the Sri Lankan agricultural supply chain context were identified and collected through self-experience and related institutes. The Agricultural department's Good Agricultural Practice certification process was studied to get data on the existing certification process. Furthermore, Hector Kobbakaduwa Agrarian Research and Training Institute’s publications were used to gather data on local food supply chain. All the actors who are engaged with the supply chain must be able to interact with the system to achieve the goal. Each transaction and events related to a product is validated by peers of the blockchain system. Product ownership is changed for each relevant transaction. A token-based mechanism is used to indicate the farmers’ reputation with their products. Farmers can place a certification request regarding their products and, they can be gained reputation tokens for each certification done by peers. A unique Quick Response (QR) code is used to identify each product container or package. In each step of the supply chain, the QR code is used to validate physical product with the virtual product. Consumers will be able to ensure the origin and the quality of each product by scanning the QR Code, with the mobile application. The proposed system will be implemented, following a systematic review of a literature as well as a series of interviews with stakeholders, as a prototype on a private blockchain and validated with the involvement of real users to arrive at conclusions.Item Effective information sharing and integration to enhance performance of fresh produce supply chains: A systematic review of literature.(International Research Symposium on Pure and Applied Sciences, 2017 Faculty of Science, University of Kelaniya, Sri Lanka., 2017) Weeabahu, W. M. S. K.Effective information sharing and integration are enablers of supply chain integration and have become a major driver of supply chain performance improvement. Agricultural supply chains involve larger number of stakeholders including, private sector, logistics partners, and regulatory bodies. From mud to mouth, multiple supply chain player’s information requirement varies through supply chain processes. The lack of information sharing and integration among supply chain players, result in inefficiency in the supply chain processes. The purpose of this paper is to systematically review the literature on effective information sharing and integration in the fresh produce supply chains for performance enhancement. In defining the scope of the study mainly fresh fruits and vegetable supply chain related literature is considered for the review. A comprehensive systematic review of existing literature specifically focusing on the supply chain information flow and supply chain performance is carried out to identify supply chain players’ information network and their various information needs. In most research studies, information integration has been viewed as information sharing and collaborative planning among supply chain entities using information and communication, technology. Even though the relationship between effective information integration and supply chain performance is not clearly examined, various studies have recognized the presence of a tacit relationship. Effective information flow from upstream to downstream as well as downstream to upstream with fresh produce supply chain entities affect the performance of supply chain. Some of the past research studies highlighted the importance of analyzing and validating exact information needs of the supply chain entities for effective supply chain performance. These findings of the study are useful for policymakers in formulating supply chain performance improvement strategies and for practitioners to understand the supply chain players’ information specific needs and network for supply chain performance improvement.
