Unsafe water reuse in the informal irrigation sector dominates in the Global South and requires more attention to protect food safety and public health. Promoting formal wastewater use in conjunction with (usually constrained) investment in treatment capacities is not sufficient in LMIC. New approaches and indicators are needed across the formal and informal reuse sectors to increase food safety and monitor progress on safe reuse. Current reuse guidelines need to be updated with greater attention to policy, regulations, investments, and behavior change for a higher implementation potential.

支持和监测中低收入国家农业废水安全利用的挑战


在南半球国家，非正规灌溉部门的不安全水再利用占主导地位，需要更多关注以保护食品安全和公共卫生。在中低收入国家，促进废水的正式利用与处理能力投资（通常受到限制）是不够的。正式和非正式再利用部门需要新的方法和指标，以提高食品安全并监测安全再利用的进展。当前的重用指南需要更新，更加关注政策、法规、投资和行为变化，以获得更高的实施潜力。
