This comprehensive study synthesizes two decades of international research to uncover how tannins – natural compounds abundant in many plants – play a pivotal role in accelerating wound recovery and reducing inflammation. The authors delve into the biochemical pathways, therapeutic mechanisms, and clinical applications of tannins, demonstrating how these compounds act as natural antioxidants, antimicrobial agents, and physical barriers that protect damaged tissue. The paper also highlights modern extraction methods, applications in diabetic wound care, and the potential for sustainable biotechnological innovations in natural medicine. Editor’s note: “This article is one of my personal favorites from our latest issue. It represents the kind of scientifically grounded, interdisciplinary research we aim to publish – bridging natural sciences, medicine, and biotechnology with a clear, evidence-based narrative. The authors have made a substantial contribution to understanding natural healing mechanisms.” This publication underscores IJDR’s commitment to promoting innovative, high-impact research that connects digital, biological, and applied sciences across disciplines. 📘 Citation:Domingues de Barros, M., da Cunha, R.

Tannins are secondary metabolites constituents of plants whose action on wounds is the most reported. The present work aims to do an exploratory descriptive literature review of tannins action as a therapeutic agent in wound healing through different mechanisms. Tannins work by forming a film on the lesion, creating an environment favorable to cell anticipation and extracellular matrix agents such as collagen and elastin, also having antioxidant and anti-inflammatory action. This polyphenol can adapt to different conditions according to their specificity and degree of aggression, thus proving to be superior to conventional means that have already been eliminated, leading to a brief discussion about these mechanisms that act synergistically during the healing process assisting in the development of new therapies.

New Article Published: Analysis of Climate Change and PM₁₀ Air Pollution
Historical and Contemporary Analysis of Climate Change and PM₁₀ Air Pollution in Plovdiv The International Journal of Digital Research (IJDR) is pleased to announce the publication of a new research article by Krasimir Stoyanov, Galina Bezinska, and Ruslana Ivanova-Dobreva from the South-West University “Neofit Rilski,” Bulgaria. This study provides an in-depth examination of the relationship between long-term climate trends (1976–2024) and PM₁₀ air pollution dynamics (2015–2024) in the city of Plovdiv. The authors highlight a significant warming trend of +1.5–2°C, increasing precipitation variability, and persistent air pollution challenges during winter months due to solid-fuel heating and temperature inversions. 📘 Citation:Stoyanov, K., Bezinska, G., & Ivanova-Dobreva, R.

Long-term climate data spanning 1976–2024, together with contemporary air quality records from the Kamenitsa and Trakia automatic monitoring stations for the period 2015–2024, were analysed. The results indicate a marked increase in annual mean temperature of approximately 1.5–2°C over the past five decades, accompanied by greater variability in precipitation, manifested through alternating droughts and short but intense rainfall events. PM₁₀ pollution persists as a major environmental challenge, with peak concentrations occurring during the winter months, primarily due to domestic solid-fuel heating and frequent temperature inversions. Exceedances of the EU and WHO daily limit value of 50 μg/m³ are widespread. A strong correlation was observed between meteorological conditions and PM₁₀ dynamics: calm conditions and inversions facilitate particle accumulation, whereas precipitation and stronger winds exert a cleansing effect. The study underscores the need for improved monitoring, restrictions on solid-fuel heating, and the adoption of sustainable urban policies to reduce environmental and public health risks.

New Article Published: The Role of European Union’s Agricultural Policy
The Role of European Union’s Agricultural Policy in the Development of Rural Areas in Bulgaria A new review article by Valentin Shlyakov, PhD student at the Department of Geography, Ecology and Environmental Protection, South-West University “Neofit Rilski”, has been published in International Journal of Digital Research, Volume 1, Issue 3 (2025), pp. 53–71. The article provides a comprehensive analysis of the impact of the EU’s Common Agricultural Policy (CAP) on Bulgaria’s rural development. It examines how CAP instruments under Pillar I (direct payments) and Pillar II (rural development programmes) have influenced the modernization of agriculture, environmental sustainability, economic diversification, and demographic resilience in Bulgaria since its EU accession. Key findings highlight significant improvements in farm productivity, biodiversity protection, and infrastructure development, while also addressing persistent challenges such as land fragmentation, subsidy inequality, and rural depopulation. The study further offers strategic policy recommendations for the post-2027 period, emphasizing digital transformation, targeted support for small and medium-sized farms, and stronger integration with the EU Green Deal. 🔗 DOI: https://doi.org/10.63711/ijdr.net20250306📚 Citation: Shlyakov, V.

The Role of European Union’s Agricultural Policy in the Development of Rural Areas in Bulgaria
Valentin Shlyakov PhD Student Department of Geography, Ecology and Environmental Protection Faculty of Mathematics and Natural Sciences South-West University “Neofit Rilski”, Blagoevgrad, Bulgaria ORCID ID: 0009-0002-7414-7825 E-mail: shlyakov@swu.bg Download https://doi.org/10.63711/ijdr.net20250306 ABSTRACT This article critically examines the role of the European Union’s Common Agricultural Policy (CAP) in shaping the development trajectory of rural areas in Bulgaria. Emphasis is placed on the evolution of CAP measures, their economic, social, and environmental impacts, and their contribution to the structural transformation of Bulgarian agriculture since EU accession. The analysis explores key policy instruments under Pillar I (direct payments) and Pillar II (rural development programmes), with a focus on modernization, competitiveness, sustainability, and demographic resilience. Drawing on strategic policy documents, statistical data, and comparative assessments, the study evaluates the extent to which CAP interventions have supported income stability, stimulated employment, enhanced biodiversity protection, and improved infrastructure in rural regions. Findings indicate that EU support has significantly increased farm productivity, diversified local economies, and strengthened environmental practices, although persistent structural challenges, such as land fragmentation, unequal distribution of subsidies, and demographic decline, continue to limit the full realization of rural development objectives. The article concludes by highlighting policy priorities and strategic directions for the post-2027 programming period, including digital transformation, targeted support for small and medium-sized farms, and stronger integration with cohesion and Green Deal policies.

Following the PRISMA guidelines, a systematic research was conducted. Evidences recognize that ICT boosts data-driven management, automation of service delivery and also community participation, improves strategic planning, and boosts crisis resilience. In addition, innovation technologies like gamification, virtual reality, and intelligent infrastructure enrich the tourist experience, particularly for young generations such as Generation Z. However, although the above developments occur, there are challenges that come in terms of digital dependency, unequal access to technology, as well as a potential loss of authenticity in tourist experiences. Overall, ICT is an innovative driver of active tourism, guiding future models of competitiveness, sustainability, and innovation through technology use, marketing, and visitor experience.
