PRECISION AGRICULTURE TECHNOLOGIES FOR SUSTAINABLE CROP PRODUCTION: A SYSTEMATIC LITERATURE REVIEW

Abstract

 Background: The global agricultural sector faces unprecedented challenges in meeting food security demands while minimizing environmental degradation. Precision agriculture technologies (PATs) have emerged as a transformative approach to achieving sustainable crop production through site-specific management and resource optimization. Objective: This systematic literature review synthesizes current evidence on the application, effectiveness, and sustainability outcomes of precision agriculture technologies for crop production. Methods: Following PRISMA 2020 guidelines, a comprehensive search was conducted across five major databases (Scopus, Web of Science, PubMed, IEEE Xplore, and ScienceDirect) for studies published between 2015 and 2025. A total of 1,268 records were identified, of which 42 studies met the inclusion criteria. Quality assessment was performed using the modified Newcastle-Ottawa Scale. Results: The review reveals that precision agriculture technologies demonstrate significant potential for enhancing both economic and environmental sustainability. Variable rate technologies showed the strongest economic benefits (22.3% ROI increase), while remote sensing and IoT-based systems improved nitrogen use efficiency by 15.1% and reduced pesticide application by 12.8%. Key technologies include GPS guidance systems, unmanned aerial vehicles, sensor networks, and artificial intelligence-driven decision support systems. However, adoption barriers persist, particularly for smallholder farmers in developing regions. Conclusion: Precision agriculture technologies offer a viable pathway toward sustainable intensification of crop production. Future research should prioritize multi-scale technology integration, climate-resilient systems, and inclusive solutions addressing the needs of diverse farming contexts. Policy support and capacity building are essential for realizing the full potential of these technologies in achieving global food security and environmental sustainability goals.
