Blockchain is a technology that can be applied in different sectors to solve various problems. As a complex system, agribusiness presents many possibilities to take advantage of blockchain technology. The main goal of this paper is to identify the purposes for which blockchain has been applied in the agribusiness sector, for which a PRISMA-based systematic review was carried out. The scientific literature corpus was accessed and selected from Elsevier’s Scopus and ISI of Knowledge’s Web of Science (WoS) platforms, using the PRISMA protocol procedures. Seventy-one articles were selected for analysis. Blockchain application in agribusiness is a novel topic, with the first publication dating from 2016. The technological development prevails more than blockchain applications since it has been addressed mainly in the Computer Sciences and Engineering. Blockchain applications for agribusiness management of financial, energy, logistical, environmental, agricultural, livestock, and industrial purposes have been reported in the literature. The findings suggest that blockchain brings many benefits when used in agribusiness supply chains. We concluded that the research on blockchain applications in agribusiness is only at an early stage, as many prototypes are being developed and tested in the laboratory. In the near future, blockchain will be increasingly applied across all economic sectors, including agribusiness, promoting greater reliability and agility in information with a reduced cost. Several gaps for future studies were observed, with significant value for science, industry, and society.

Information technologies such as blockchain are developing fast, overcoming bottlenecks, and quickly taking advantage of their application. The present study analyzes recent changes concerning the benefits, disadvantages, challenges, and opportunities of blockchain applications in agribusiness. Interviews were conducted with and a questionnaire was applied to professionals working in the development and application of blockchain technology in agribusiness, to compare their perception of the recent advances. The results showed that the importance of blockchain technology to improve governance and information flow along supply chains has increased, and this is the main perceived benefit. The main disadvantages were removing intermediaries and the high cost of implementing the technology. The absence of a widely accepted platform in blockchain operations is the leading and growing challenge, while patterns for blockchain technology seem to be being overcome. The integration of blockchain with new technologies, and the competitiveness provided by the technology, are seen as the main and growing opportunities. Despite the study limitations, we conclude that the benefits and opportunities associated with blockchain application in agribusiness outweigh the challenges and disadvantages in number and importance, and are becoming more relevant.

O objetivo desse estudo foi analisar a viabilidade econômica do cultivo de Tilápia do Nilo em um sistema de produção semi-intensivo em uma propriedade no interior do noroeste do Rio Grande do Sul. Foi realizada uma pesquisa de campo, com o acompanhamento das atividades realizadas na propriedade para a obtenção dos dados e informações relevantes ao estudo. Por meio dos custos e receitas da propriedade foram calculados alguns indicadores considerados essenciais como: Valor Presente Líquido, Payback, Taxa Interna de Retorno e Índice de Lucratividade. Ao final do estudo os índices calculados, apresentaram resultados positivos de viabilidade econômica para a propriedade rural, por ser um projeto de longo prazo, são necessários cinco anos para ter retorno sobre o valor investido, a partir desse período, a atividade é lucrativa. Este estudo apresenta bons resultados para todos os índices calculados, tanto o VPL e a TIR resultaram em valores positivos indicando que o cultivo de tilápias remunerará mais que a taxa mínima esperada pela propriedade rural.
