This systematic review analyzed a total of 109 scientific articles with the aim of identifying, organizing, and synthesizing academic output related to digital literacy, technology adoption in agricultural sectors, digital skills, and socioeconomic and cultural factors that influence the implementation of emerging technologies. Peer-reviewed academic publications available in open access and written in English were reviewed, complying with the PRISMA protocol guidelines. They came predominantly from Europe, Asia, and Latin America, which allowed for a global perspective. Quantitative, qualitative, and mixed approaches were applied, highlighting the use of surveys, interviews, and bibliometric analysis. Factors affecting the adoption of precision agriculture by smallholder farmers, challenges for the implementation of technologies in rural contexts, and sociocultural barriers to technological innovation were evaluated. The trend focuses on the need for sound public policies, continuous training strategies, technological accessibility, and contextualized approaches to ensure effective technology adoption. In conclusion, a broad and critical overview of the advances, limitations, and challenges surrounding digital literacy and technology adoption is provided as a basis for an in-depth debate on the digital transformation of contemporary agriculture.

Rural environment is suffering from serious problems, as reflected in the term “Empty Spain”. One of these problems is the pronounced depopulation that rural areas suffer in our time, so creating links with the land thanks to education is of great interest for, among other things, establishing population in rural areas. Interdisciplinary education becomes relevant today as the necessary education in our current world capable of providing answers and solutions to the social demands of our time. Interdisciplinary STEM education had the United States of America as its cradle in the 1990s; later it passed to the acronym STEAM when the Arts were later introduced, this is how you find a true interdisciplinary education. Since 2010, government policies have been developed in the USA, highlighting the Educate to Innovate program and in that same country the STEM4SD Education program, which develops education for sustainability by creating links with the local population. Precisely, this article will collect the educational policies that have been carried out in the USA for the development of this type of education. In this article and thanks to the analysis of certain programs, the importance of interdisciplinary STEM and STEAM education in our days will be exposed for the promotion of sustainability directed towards sustainable development, thereby creating more sustainable societies made up of more sustainable citizens, highlighting the importance of education for sustainability through STEM and STEAM education creating links with the land for the improvement of the rural world, which means establishing population, among other aspects.

Interdisciplinary STEM and STEAM education gives us the opportunity for training students to achieve all educational objectives in a sustainable development framework. Land in a rural area is a scenario with a range of educational resources for the development of STEM and STEAM projects to train students to interact with the rural environment. The possibilities of the land in order to prepare students for the needs of today’s world are linked and sensitized to the environment. In this article, we will offer contemporary examples of STEM and STEAM projects that have been carried out in Latin America. These projects are being developed in which young people establish links with their environment, territory, and the local environment surrounding them. We must look carefully at projects and works in which students’ ties to their land and environment are valued through the STEM and STEAM education necessary today. In this scenario, a comparison has been made between the projects in Latin American countries and Spain.

The Mediterranean model, introduced by Ancel Keys, has gained significant importance from the perspective of sustainability. This is why the Mediterranean diet is now called a sustainable diet. This study focuses on legumes, protein-rich foods of vegetable origin, cultivated in the area, as their production and use in cooking are highly sustainable. The analysis covers their consumption over the last 10 years in the entire Mediterranean area, looking specifically at Spain. The objectives of this work are to analyze the production of legumes in the Mediterranean area, taking into account the fact that they are an important environmental as well as food resource, and to analyze how the consumption of legumes has changed in certain countries bordering the Mediterranean in relation to social and cultural changes, with particular attention to the pandemic. The study shows how, in Spain, since 2020, the consumption of legumes has increased, demonstrating that in emergency situations, different dietary choices are made. In addition, it shows how legumes are an excellent source of vegetable protein and an important environmental resource from the perspective of sustainability.

Background: Plant genomes have been transformed with full-length cDNA copies of viral genomes, giving rise to what has been called 'amplicon' systems, trying to combine the genetic stability of transgenic plants with the elevated replication rate of plant viruses. However, amplicons' performance has been very variable regardless of the virus on which they are based. This has boosted further interest in understanding the underlying mechanisms that cause this behavior differences, and in developing strategies to control amplicon expression. Results: Nicotiana benthamiana plants were transformed with an amplicon consisting of a full-length cDNA of the potyvirus Plum pox virus (PPV) genome modified to include a GFP reporter gene. Amplicon expression exhibited a great variability among different transgenic lines and even among different plants of the same line. Plants of the line 10.6 initially developed without signs of amplicon expression, but at different times some of them started to display sporadic infection foci in leaves approaching maturity. The infection progressed systemically, but at later times the infected plants recovered and returned to an amplicon-inactive state. The failure to detect virus-specific siRNAs in 10.6 plants before amplicon induction and after recovery suggested that a strong amplicon-specific RNA silencing is not established in these plants. However, the coexpression of extra viral silencing suppressors caused some amplicon activation, suggesting that a low level of RNA silencing could be contributing to maintain amplicon repression in the 10.6 plants. The resistance mechanisms that prevent amplicon-derived virus infection were also active against exogenous PPV introduced by mechanical inoculation or grafting, but did not affect other viruses. Amplicon-derived PPV was able to spread into wild type scions grafted in 10.6 rootstocks that did not display signs of amplicon expression, suggesting that resistance has little effect on virus movement. Conclusions: Our results suggest that amplicon-derived virus infection is limited in this particular transgenic line by a combination of factors, including the presumed low efficiency of the conversion from the transgene transcript to replicable viral RNA, and also by the activation of RNA silencing and other defensive responses of the plant, which are not completely neutralized by viral suppressors.

The commercialization of Km 0 agricultural and livestock products represents a strategic opportunity to enhance rural economic resilience and reduce greenhouse gas emissions in the food sector. This paper presents an original, policy-oriented framework that connects Km 0 distribution models with measurable CO₂ reductions, proposing a structured system of economic incentives to support their adoption. Grounded in a mixed-methods approach, including normative analysis, empirical modeling, and a regional case study in Galicia, Spain, we demonstrate the alignment of Km 0 policies with the EU’s Common Agricultural Policy (CAP) 2023–2027 and the Sustainable Development Goals (SDGs). Findings reveal substantial potential for environmental mitigation, improved farm profitability, and revitalization of rural economies. This work provides a comprehensive roadmap for integrating Km 0 into national agricultural strategies, supported by data-driven justification and scalable implementation models.
