The purpose of this study is to review the literature on the Delphi method, its characteristics and current applications through an analysis of recent most-cited scientific papers, with an emphasis on three axes, namely, the number of rounds used, stakeholder participation relevance or only academic experts’ participation and the possibility of using indicators or techniques different from those related to descriptive statistics. In total, 57 papers were initially reviewed, 10 of them with a high citation rate. Then, an analysis was made of papers in Scopus for the period 2015-2018 published in the Technological Forecasting and Social Change Journal and in the Futures and Foresight Journal, which had the characteristic of displaying quartile Q1 or Q2 in Scimago in addition to being in Scopus. Among the main results, the authors observe the tendency to use fewer rounds, a higher prevalence of stakeholder participation and not only academic experts but also the use of new types of modified Delphi such as real-time spatial Delphi, Delphi group, market Delphi, real-world Delphi and policy Delphi. Among the conclusions, the possibility of using other indicators or complementary techniques to the descriptive statistics is highlighted such as number of justifications or comments between rounds, coefficients to quantify the competence or degree of expertise of the participants, measures of the perception of the expert on the usefulness of the presented feedback, graphs of the number of arguments according to the number of questions, the Wilcoxon Ranked Pairs Test, the k means, Kolmogorov–Simonov test and the Mann–Whitney U-test.

In this article, we focused on studying the current barriers to implementing innovations in order for the agricultural sector to become more sustainable. Through a systematic literature review (SLR), 73 scientific articles were obtained with a search equation in SCOPUS. Of these, 48 were analyzed because of the mention of an obstacle preventing the sector from implementing innovations towards sustainability. Information related to the publication year, abstract, authors, keywords, innovation, innovation type, relationship with Fourth Industrial Revolution (4IR), identified barrier, nature of the barrier (internal/external), agricultural subsector, country, and methodology of each article was identified, and with VantagePoint software, a technological surveillance technique was applied as a quantitative analysis of the information. The United States is the country with the most publications related to the subject. The most mentioned keywords were “Sustainable Agriculture”, “Agroecology”, “Climate Change”, “Innovation”, and “Organic Farming”. Additionally, a qualitative analysis showed 43 types of innovations, 16 of them related to technology. “Organic Agriculture” is the most mentioned innovation, followed by “Genetic Engineering” and “Precision Agriculture”. In addition, 51 barriers were identified, 28 external to farmers and 23 internal. “Lack of policies that promote that innovation Innovative Practices” is the most mentioned barrier, followed by “Epistemic Closure”, “Unfavorable Regulation”, Climate-Smart Agriculture, and “Unskilled Labor”. This article is intended not only to show trends in the barriers to innovation that prevents the achievement of sustainability that the agricultural sector needs, but also to serve as an input for the development of policies that provide solutions to these impediments. It was shown that 17 out of the 28 external barriers are related to topics that could be solved by formulating policies, laws, incentives, guidelines, and regulations.

This study aims to review and synthesize the rapidly evolving literature on technology transfer from universities, and the concepts and models included in it, from a knowledge-flow approach to find the factors contributing to its performance. This article provides a perspective on recent work, focusing on empirical studies on technology transfer in universities conducted in the last 32 years from a knowledge-based vision. The study was carried out from a systematic literature review in the Scopus, Web of Science, ScienceDirect, and SpringerLink databases on 135 articles selected and evaluated by peers from critical surveillance factors such as technology transfer, knowledge flow, and university–industry relationship, among others. It was possible to identify 75 factors that, from a knowledge-based vision and specifically from a knowledge-flow approach, permit and contribute to the performance of technology transfer generated from research processes in universities. We classified studies into four categories according to their approaches, each with their dimensions and factors: management of knowledge, resources and capabilities, management of technological transfer, and the university–industry relationship. This classification permitted not only identification but also the systematization of the different factors and related authors that, from a knowledge-flow approach, contribute to the performance of technological transfers in universities, reflecting their efficiency and effectiveness. In this respect, absorption capacity and open innovation are topics which are worthy of exploration.

Open innovation, understood as a strategy for business competitiveness, has experienced growing relevance, even in traditional economic sectors, such as agri-food. This article focuses on the trends and challenges of open innovation applied to the agri-food field, based on two approaches, a Systematic Literature Review (SLR) and a structured survey, answered mainly by micro-, small-, and medium-sized enterprises (MSMEs). For the SLR, the Scopus bibliographic database was chosen. Documents were filtered by type, novelty, and impact factor of the journal (based on the Scimago Rank). The final selection included 50 articles that were deeply analyzed. In addition, the survey was applied to 57 agri-food companies from the department of Nariño (Colombia), establishing a diagnosis of the extent of openness of their collaborative barriers and innovation capacities. The review’s results revealed a marked European dominance in this research field. Product co-creation, eco-innovation, and bioeconomy are main fields of interest and application of open innovation. The challenges identified are related to intellectual property rights and effective communication between stakeholders. The survey was successful in establishing a statistically significant correlation between innovation performance and collaboration with external partners. As a conclusion, an open innovation approach can provide dynamism and cohesion in agri-food systems.
