Analyzing complexities in the Brazilian soybean supply chain: a systems thinking and modeling approach

Abstract

Purpose This study aims to analyze the complexities of the Brazilian soybean supply chain (SSC) and develop strategic interventions to improve the origin system’s performance. Design/methodology/approach This study used stakeholder interviews to identify the SSC bottlenecks and determine and assess drivers of competitiveness. A methodological framework based on the systems thinking approach for developing long-term structural changes was used. The problem was structured using behavior over time graph and causal loop modeling to propose three investment strategies to solve the logistics problem in SSC. Findings This study highlights the gaps in coordination between stakeholders and the public sector regarding the public policy for infrastructure investment. Three strategic interventions were developed to address the agro-industrial logistical problem, namely, investment in storage, multimodal transport systems and improvements in existing transport infrastructure. To overcome transport and storage logistics limitations, the authors suggest different forms of partnerships, including public-private partnerships. Research limitations/implications This research is limited to evaluating an agricultural commodity (soybean) and does not include its by-products. The sample of stakeholders was limited and the boundary of analysis was Brazil. Nevertheless, the study showed how strategic interventions could be developed following a holistic analysis. Practical implications The proposed integrated approach illustrates the development of three strategic initiatives. It can be implemented by stakeholders, including the public sector, which is the basis for providing assertive long-term investments in Brazilian logistics. Social implications The SSC analysis could promote the implementation of systemically determined interventions and strategies. It could significantly improve the performance of agricultural systems and help the formulation of public policies aimed at rural development. Originality/value The use of system dynamics to identify intervention points is an essential contribution to mitigating the SSC’s hindrances. Moreover, the combining methodologies resulted in comprehensive intervention strategies.

Brazilian soybeans as feed for livestock in Europe: an insight into the nitrogen flows

“…Furthermore, Brazil is hindered by low quality highways, too little and inefficient railway services and long wait times at ports in the harvest season. All these factors contribute to increased losses in production and an upsurge in costs (Oliveira and Scheneider 2016 ; Filassi et al 2021 ; Lopes 2021 ).…”

“…Higher nitrogen outflows to the environment are concentrated in the Brazilian production chain, with the impact of harvest and logistic losses being significant on the environmental pressure of N r ; therefore, in applying a scenario without any loss in harvesting and logistics, the NCI showed an average reduction of 2.84% in the evaluated period. These results highlight the need for better governmental policies to improve soybean production in Brazil (Filassi et al 2021). Currently, the logistics, harvesting, storage and transportation of Brazilian soybean is based on long distance routes to the international market (Oliveira and Scheneider 2016;Lopes 2021).…”

Efeito da aplicação boratada em diferentes estádios fenológicos na qualidade fisiológica de sementes de soja

“…Os avanços significativos da produção e o aumento na capacidade produtiva da soja brasileira estão aliados aos avanços científicos e à disponibilização de tecnologias no setor produtivo, como a disponibilização tecnológica de fertilizantes minerais (Pereira et al, 2020;Filassi et al, 2021). De acordo com o intenso crescimento populacional, a utilização de programas de melhoramento da soja tem sido crescente e fundamental, pois contribui de forma significativa no desenvolvimento de sementes e de cultivares cada vez mais resistentes aos estresses bióticos e abióticos, eficientes na absorção de água e nutrientes, competitivas e altamente produtivas (Lopez et al, 2021).…”

Lean Manufacturing: Mapeamento de fluxo e cadeia de valor de uma indústria de produtos apícolas

“…Mesmo durante o período de crise causado pela pandemia de Covid-19 (SCHEIDGEN et al, 2021), o agronegócio nacional registrou crescimento em diferentes índices, como de valor bruto da produção ou na soma de bens e serviços gerados, por exemplo. Os resultados alcançados em volume e receita consolidam o Brasil como um dos principais players mundiais na produção e exportação agropecuária (FILASSI et al, 2021), principalmente envolvendo soja, café, suco de laranja, açúcar, carne de frango, carne bovina, milho e carne suína (CNA, 2021). Em meio ao agronegócio está a agroindústria.…”
