New Framework for Antimicrobial Resistance Risk Management in Agricultural Water Reuse

As global food demand rises and freshwater resources become increasingly scarce, a newly published international study is shedding light on the critical role of Antimicrobial Resistance (AMR) management in sustainable agriculture. The paper, titled “A Framework for Antimicrobial Resistance Risk Assessment, Monitoring, and Risk-Reduction Practices along the Reused Water–Soil–Crop–Human Continuum,” has been published in the prestigious journal Environmental Science & Technology.

The publication features a significant contribution from Alfieri Pollice of the National Research Council of Italy (CNR), a key partner in the universwater project. The research addresses a vital gap in current resource management by integrating “One-Health” and “One-Water” approaches to tackle the challenges of safe water reuse in crop production.

As traditional water sources dwindle, irrigating crops with reclaimed water has become an essential practice for global food security. However, this transition requires a robust understanding of how antimicrobial resistance can move through the water-soil-crop-human continuum. The framework proposed in this study provides a comprehensive overview of risk management practices, regulatory considerations, and the various pathways of human exposure.

By defining primary contamination entry points and potential barriers such as contaminant dissipation in soil and post-harvest management, the research offers a roadmap for more targeted guidance in water quality assessment. The authors emphasize that managing AMR is not merely a technical challenge but a fundamental aspect of maintaining the sustainability of agricultural systems in a climate-stressed world.

This collaborative effort was conducted by an international multidisciplinary team of experts under the leadership of Edward Topp. The contribution of the universwater project through CNR highlights the project’s ongoing commitment to high-level scientific research and the development of innovative solutions for the global water sector. The findings are expected to influence future policy and practice regarding the implementation of advanced wastewater treatment and alternative irrigation sources.
