Increasing economic pressure is pushing the agri-food industry to choose yield instead of environmental care, whereas added value should be ideally created without radically deflating food output whilst using harmless practices. In this regard, several topics have been commenced in this paper, directly referring to the research results. The starting point of this study's design locates the key scientific subtopic that shapes the present academic interest and is followed by a convergence analysis based on the metadata processed after querying the Scopus database in a relevant manner. This facilitated to conclude this study with the interest analysis in form of a heat guide that is pointing towards current research trends. This specific paper aims at revealing emerging convergence points in research literature, quantitatively measuring peer-reviewed bibliometric metadata. The main research result refers to the surprising identified nexus point that confers a multidimensional approach to food security fulfillment, reflecting current sustainable trends, as well as the potential for increasing agricultural economic performance. Agriculture is known to become a more visible player in the climate change mitigation scene, especially through efficient resource allocation. However, the results of this paper indicate that key sustainability-driven elements, such as renewable energy, are already shaping the agri-food industry, as well as the research interests in this field. In the literature, the converging theme in the case of food security and added value is that of biomass, a possible equilibrium point that calls for a more economical-competitive orientation of the academic research work, without neglecting the sustainability factor. In this regard, research interests will continue to be influenced by the implementation of the SDGs roadmap and of the European Green Deal.
