Blockchain for agricultural sector: the case of South Africa

New technologies are playing a fundamental role in the postmodern era of globalization where interpersonal interactions at the international level and the exchange of goods, services, information and capital are the basis of all activities. The agriculture sector is constantly facing numerous challenges including the steady growth of the population, climate change, the increasing number of catastrophes, the loss of biodiversity and the spread of parasites. This paper analyzes the impacts of Blockchain applications in agriculture and the food supply chain, through a survey literature review, providing the various players in the agriculture value chain with new tools and key technologies to improve production and distribution processes. To demonstrate the importance of applying the Blockchain in the agriculture sector, especially for emerging countries, the case of South Africa is examined. This focus is one of the unique aspects of this paper, which is the first to deal with this kind of solution applied to the South African context. Our findings indicate that Blockchain, in the e-agricultural context, has the potential for reshaping the entire sector, contributing also to the resolution of the food crisis. This paper discusses the overall implications, limits, challenges and potentials of these applications, from a critical point of view.
