    The transition to more sustainable and climate-resilient agriculture is an urgent challenge in agricultural regions of developing countries such as Lambayeque (Peru), especially in rice cultivation. In this context, digital literacy is emerging as a key enabler for accessing climate data, adopting precision agriculture technologies, and implementing sustainable agricultural practices. However, there are gaps linked to sociodemographic variables such as age, which can moderate these technology adoption processes. The objective of this study was to analyze the patterns of association between digital literacy, access to finance, risk perception, and the adoption of sustainable agricultural practices, and to examine whether age moderates the association between digital literacy and access to climate data. To this end, a quantitative, non-experimental approach was applied, using Partial Least Squares Structural Equation Modeling (PLS-SEM). The sample consisted of 101 rice farmers in the Lambayeque region, who were given a validated questionnaire that included five theoretical constructs measured using Likert scales. The results of the structural model confirmed that digital literacy has a positive and significant association with access to climate data (β = 0.461, p < 0.001) and with the adoption of sustainable agricultural practices (β = 0.259, p = 0.015). A positive association was identified between access to finance and risk perception (β = 0.411, p < 0.001). Age was negatively associated with digital literacy (β = −0.196; p = 0.027); however, the formal moderation test (DL × Age) was not significant (β = −0.054, p = 0.421), so there is no evidence that age moderates the association between digital skills and access to climate information. These findings support the design of differentiated interventions that incorporate intergenerational digital training, inclusive financing policies, and hybrid technology transfer strategies tailored to access gaps. Taken together, the evidence is consistent with the idea that reducing the digital divide can strengthen agricultural sustainability and climate resilience in rural contexts in Latin America.

    Digital Literacy and Technology Adoption in Agriculture: A Systematic Review of Factors and Strategies
    (Multidisciplinary Digital Publishing Institute (MDPI), 2026-09-01) ; ;
    Lucini-Baquero, Cristina
    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.

    Background/Objectives: Oreganum vulgare essential oil (OEO) is safe, effective, multifunctional, and widely used. This study aimed to evaluate OEO’s chemical composition and antimicrobial activity in vitro against S. aureus and E. coli. Methods: The composition of OEO was determined by gas chromatography–mass spectrometry (GC-MS). Results: Compounds included monoterpenes with known antimicrobial activity, such as 2-menthen-1-ol (36.33%), linalyl acetate (9.26%), terpinene-4-ol (9.01%), 4-thujanol (6.33%), menthen (5.81%), sabinene (5.18%), and carvacrol methyl ether (5.14%). Conclusions: OEO had a strong antimicrobial activity with a minimum inhibitory concentration (MIC) of 1.90 mg/mL for S. aureus and 0.49 mg/mL for E. coli after 18 h incubation. The minimum bactericidal concentration (MBC) was 7.9 mg/mL against S. aureus and 0.99 mg/mL against E. coli. Thus, OEO could be used as a natural antimicrobial against S. aureus and E. coli infections.

    Aplicación del ultrasonido para conservar las propiedades antioxidantes de la pitahaya
    (Latin American and Caribbean Consortium of Engineering Institutions, 2024-01-01)
    Pitahaya fruit has a considerable content of antioxidant and nutraceutical substances. Traditional techniques and thermal treatments used in fruit processing alter the phytochemical and nutritional components and limit their utilization, so a modern and suitable technology was sought to help preserve its components, finding ultrasound as one of the techniques that favors the preservation of the nutritional properties, bioactivity and antioxidants of the fruit pulp and its derived or processed products. In the processing of the pitahaya, the pulp was extracted by cutting it into slices and freezing it at -50°C, then freeze-drying it for about 49 hours. The dry ground sample was macerated in methanol for 7 days, separated into portions to determine the antioxidant capacity by DPPH method and analyzed by spectrophotometer. In a filtered portion, the antioxidant capacity was determined directly, and other portions were subjected to ultrasound before analysis, evaluating the times, power and frequency of application in order to preserve the natural antioxidant and nutritional composition of the pulp; it was found that the sample to which ultrasound was applied for 20 minutes at 180 W power and 40 kHz frequency was the most relevant to preserve the antioxidant capacity of the pitahaya pulp. © 2024 Latin American and Caribbean Consortium of Engineering Institutions.
