Abstract
This study adopts a policy‐centric perspective to explore the complex relationship between sustainable nitrogen management (SNM) and the health risks associated with unsafe drinking water. The critical policy challenge lies in balancing the essential role of nitrogen fertilizers in achieving high agricultural productivity with their detrimental environmental impacts. Using the Sustainable Nitrogen Management Index (SNMI) as a measure of nitrogen use efficiency, this research analyzes data from 143 countries spanning 1990 to 2015. The findings reveal that SNM significantly reduces health risks by decreasing water contamination. However, food production plays a critical mediating role. Although SNM improves environmental sustainability, increased agricultural output can counteract its benefits by contributing to further water pollution. These results highlight the complex interplay between SNM, food production, and public health. The study underscores the need for integrated strategies that address both the environmental and health impacts of nitrogen use while supporting global food security. These insights provide a foundation for developing evidence‐based policies to balance agricultural productivity with safeguarding water quality and public health. They also set the stage for deeper institutional analysis. 本研究以政策为中心,探究了可持续氮管理 (SNM)与不安全饮用水相关健康风险之间的复杂关系。关键的政策挑战在于如何平衡氮肥在实现农业高产方面的重要作用及其对环境的不利影响。本研究将可持续氮管理指数 (SNMI)作为氮利用效率的衡量指标,分析了1990年至2015年143个国家的数据。研究结果表明,SNM通过减少水污染而显著降低了健康风险。然而,粮食生产发挥了关键的中介作用:尽管SNM改善了环境可持续性,但农业产出的增加可能会加剧水污染,从而抵消其带来的益处。这些结果强调了可持续氮管理、粮食生产和公共卫生之间复杂的相互作用。本研究强调,需要制定综合战略,后者能在支持全球粮食安全的同时应对氮肥使用产生的环境影响和健康影响。这些见解为制定循证政策一事奠定了基础,以平衡农业生产力与保障水质和公众健康。它们也为更深入的制度分析奠定了基础。 Este estudio adopta una perspectiva centrada en las políticas para explorar la compleja relación entre la Gestión Sostenible del Nitrógeno (GSN) y los riesgos para la salud asociados con el agua potable contaminada. El desafío político crucial radica en equilibrar el papel esencial de los fertilizantes nitrogenados para lograr una alta productividad agrícola con sus impactos ambientales perjudiciales. Utilizando el Índice de Gestión Sostenible del Nitrógeno (IGSN) como medida de la eficiencia en el uso del nitrógeno, esta investigación analiza datos de 143 países que abarcan el período 1990‐2015. Los hallazgos revelan que la GSN reduce significativamente los riesgos para la salud al disminuir la contaminación del agua. Sin embargo, la producción de alimentos desempeña un papel mediador crítico: si bien la GSN mejora la sostenibilidad ambiental, el aumento de la producción agrícola puede contrarrestar sus beneficios al contribuir a una mayor contaminación del agua. Estos resultados resaltan la compleja interacción entre la gestión sostenible del nitrógeno, la producción de alimentos y la salud pública. El estudio subraya la necesidad de estrategias integradas que aborden los impactos ambientales y de salud del uso del nitrógeno, a la vez que apoyan la seguridad alimentaria mundial. Estos conocimientos proporcionan una base para el desarrollo de políticas basadas en la evidencia para equilibrar la productividad agrícola con la protección de la calidad del agua y la salud pública. También sientan las bases para un análisis institucional más profundo.
