This systematic review examines digital transformation in post-pandemic supply chains through a bibliometric analysis of literature from 2020 to 2024. Using the PRISMA protocol, we analyzed publications from Scopus, Web of Science, and ScienceDirect databases. Results show that sustainability has become the dominant keyword in digital transformation research, with China, the United States, and India forming the main research triangle. The most influential technologies driving transformation are big data, blockchain, artificial intelligence, and Internet of Things (IoT). Co-citation network analysis revealed three major research clusters: the green cluster led by Gunasekaran and Angappa focusing on supply chain management; the red cluster led by Rahman and Muhammad Saddiq addressing implementation aspects; and the blue cluster led by Calatayud and Rodriguez examining innovation and adaptation. Organizations are shifting from purely operational approaches to more holistic transformations that integrate strategic and organizational dimensions. We identified important research gaps in developing regions and in the integration of emerging technologies with existing systems. This review enhances the understanding of post-pandemic supply chain digitization while providing a framework for future research in this rapidly evolving field.

South American coffee producers face growing challenges due to external trade dependencies and climate-induced disruptions. This study investigates the role of export market diversification as a sustainability strategy for four major regional exporters of roasted non-decaffeinated coffee: Brazil, Colombia, Peru, and Ecuador. A quantitative and comparative methodology was applied over a ten-year period using the Herfindahl–Hirschman Index (HHI) to evaluate export market concentration and the Revealed Comparative Advantage (RCA) Index—including its normalized variant—to assess international competitiveness by destination. The results reveal substantial disparities: Brazil and Colombia exhibit moderate to high diversification and relative competitiveness in select markets, while Peru and Ecuador remain dependent on a few strategic buyers, with limited or declining comparative advantages. The findings emphasize that sustained export performance in the coffee sector requires not only a broader destination portfolio but also improved positioning through trade agreements, infrastructure development, and climate-resilient innovation. This study concludes with a strategic proposal based on three pillars—commercial, logistical, and technological—to support structural transformation and enhance the long-term sustainability of the coffee trade in South America.

This study examined the sustainability of global table grape exports from 2020 to 2024, focusing on two key dimensions: market diversification and international competitiveness. Using data from Trade Map and applying the Herfindahl–Hirschman Index (HHI) and the Revealed Comparative Advantage Normalized Index (RCAN), the research analyzed the export performance of major grape-exporting countries, including Peru, Chile, the Netherlands, Italy, the United States, South Africa, and China. The results showed significant differences in both market structure and competitive positioning. Countries like Peru and South Africa demonstrated rapid export growth and high competitiveness in certain markets, but faced elevated levels of market concentration, exposing them to external shocks. In contrast, Italy and the Netherlands maintained more diversified portfolios but showed modest competitiveness. The study concluded that no country achieved an ideal balance between diversification and competitiveness. As a result, it is recommended that governments pursue integrated trade strategies that promote geographic expansion alongside measures to enhance export competitiveness. Investments in logistics, quality certifications, and market intelligence are essential to reduce vulnerability and ensure long-term export sustainability.

This study asks how diversified and how competitive banana exports from Ecuador, Colombia, Peru and Bolivia were during 2020 to 2024, and what risks arise from their market mix. The original contribution is a two-metric approach that jointly applies the Herfindahl Hirschman Index by destination to measure geographic concentration and the normalized Revealed Comparative Advantage to measure relative competitiveness. Using both indicators together creates a clear and reproducible benchmark for policy and firm decisions. A quantitative and descriptive design was applied to official trade data for HS 0803. Results show that Ecuador combined strong comparative advantage with low concentration, which supports regional leadership. Colombia expanded exports while its concentration rose, a sign of greater exposure despite solid performance in Europe. Peru lost shares and became more dependent on a few outlets, yet kept advantages in organic and niche segments. Bolivia displayed extreme concentration centered on Argentina. Practically, the findings support market diversification, staged entry into new destinations, stronger commercial partnerships, and the integration of sustainability and risk management. Theoretically, the study clarifies that diversification and competitiveness are distinct constructs and that assessing both together with transparent indices improves the diagnosis of resilience.

Esta revisión sistemática analiza la relación entre las estrategias de gestión de recursos humanos (GRH) y la retención de talento en la administración portuaria, con énfasis en Terminal Internacional del Sur (TISUR). Alineado con el Objetivo de Desarrollo Sostenible 8, el estudio aborda la intersección entre operaciones marítimas y gestión del capital humano. Siguiendo la metodología PRISMA, se seleccionaron 40 artículos indexados en Scopus y Web of Science (2006-2024) bajo un enfoque cualitativo con criterios de evaluación estandarizados. Los resultados evidencian que la implementación de marcos integrados de gestión del talento mejora la eficiencia operativa y reduce la rotación de personal. Se identificaron cinco dimensiones clave: planificación estratégica de la fuerza laboral, desarrollo de competencias digitales, sostenibilidad, diversidad y gobernanza organizacional. La capacitación en gestión ambiental incrementa la retención de personal especializado, mientras que las iniciativas de igualdad de género aumentan la satisfacción laboral. Este estudio contribuye al conocimiento teórico y práctico al proponer un marco conceptual que integra digitalización, sostenibilidad y gobernanza inclusiva como pilares esenciales para fortalecer la competitividad portuaria mediante una gestión estratégica del talento en entornos marítimos globales.

Wheat trade sustainability has become critical amid compounding shocks—pandemic disruptions, extreme weather events, and the Russia–Ukraine war—that exposed vulnerabilities in global food supply systems. This study documents how five major wheat suppliers (Australia, Canada, the United States, Russia, and Ukraine) adjusted destination structures and revealed competitive positions during 2020–2024, and whether these structural configurations coincided with more or less stable export outcomes. Using annual FOB export data from the International Trade Centre, destination concentration is measured through the Herfindahl–Hirschman Index (HHI), revealed competitive positioning is assessed using the symmetric revealed comparative advantage (SRCA) (the symmetric transformation of the Balassa RCA), and outcome stability is summarized with volatility (coefficient of variation) and maximum drawdown computed from annual export values. The United States maintained structural diversification; Canada shifted toward high concentration; Australia preserved moderate dispersion but exhibited pronounced outcome volatility; Ukraine experienced a post-2022 reconfiguration with elevated concentration and large drawdowns, whereas the Russian Federation is reported only up to 2021 due to ITC data availability in the extraction used (thus interpreted as a pre-shock baseline). Overall, export sustainability under shocks is best interpreted as a combination of destination-risk architecture, revealed positioning, and observed stability of outcomes rather than inferred from competitiveness alone.
