This paper applies the “average contribution to structural efficiency” index to measure the environmental performance of the European Union Member States’ agricultural sectors. The contribution index considers all of the possible combinations of observations when assessing states’ environmental performance.

Food loss and waste occur along the whole food supply chain and need to be addressed by dedicated strategies. Among all the stages of the food supply chain, food loss in primary production has been the least studied to date. In order to address this gap, this paper focuses on on-farm food loss, using Lithuania as a case study. The research comprises eleven crop products and five livestock products prevailing in Lithuanian agricultural production.

The aim of the paper is to investigate the energy intensity and efficiency in Lithuanian farms across different farming types and to perform the energy intensity in the European Union (EU) context. Four energy intensity indicators were chosen, and based on these indicators, the energy performance score is constructed using the simple additive weighting method.

This paper proposes the three-stage multi-criteria decision-making (MCDM) non-radial super-efficiency data envelopment analysis (NRSDEA) method with bootstrapping to study a discipline's scientific research efficiency from the university-level perspective. To ensure robust analysis, the proposed model incorporates the contextual variables describing the external environment and the random error.

This research aims to discuss the evolution of short food supply chain theory and practice in the context of three para‐ digm innovations that emerged in the post‐industrial economic system and suggest new paths for sustainable agri‐food system building. All three paradigm innovations are closely related to each other, but each changes a certain dimension of the mental model concerning the food production and delivery system.

The development of shipping companies relies on multiple financing channels and requires decisions to be made regarding fleet management. Therefore, a firm’s performance should be modeled based on multiple decision variables. The purpose of this paper is to develop a quantitative approach for determining the investment portfolio of a shipping company taking into account the equity value.

Functional principal component analysis (FPCA) is an extension of conventional principal component analysis (PCA) that allows the processing of functional data. Besides the reduction in dimensionality that is inherent to PCA, FPCA relies on fewer assumptions and offers a greater ability to visualize the functional data. Thus, FPCA can be used in, for example, social, economic, and medical research.

Energy policy affects the functioning of the economic and financial systems of countries worldwide. This paper provides a theoretical overview of the economy-energy nexus and discusses the particular cases of the energy policy dynamics amid the sustainability goals. This paper inte‐ grates multiple perspectives on the energy-economy nexus, with a particular focus on the energy trilemma, 4As of energy security and PESTEL approach.

Over the recent decades, the evolution of the European Union (EU) agricultural system has resulted in significant structural changes in member states. Knowledge about the nature and main patterns of structural change is critical to select a sustainable development path for the EU agriculture. This paper contributes to the academic discourse on structural changes in agriculture demonstrating the nexus between socioeconomic and environmental aspects of development. In this regard, results are important to understand the contribution of the EU agriculture to climate change, because study deals with energy use and greenhouse gas emissions.

Research on economic resilience in agriculture is quite complicated due to the interdisciplinary nature of the notion. In agricultural, climate change, sustainability and food security research it appears as an endogenous phenomenon rather as the main one. This study aims to contribute to conceptualization of economic resilience in agriculture, revealing current and identifying future research directions.
