While water pollution is starting to receive the attention it deserves, the contribution of agriculture requires greater consideration as current agricultural practices have an unprecedented impact on water quality. This paper reviews knowledge in selected areas of agricultural water pollution (AWP) and identifies future research needs. These include source attribution, emerging contaminants, costs and incentives for adoption of pollution reduction measures. Future research priorities include identification and testing of locally appropriate markers; modelling the effects of contaminants on biota and pathways of microbial contaminants; harmonization of data collection and calculation of economic costs of AWP across countries and projects; and how to better share relevant knowledge to incentivize improved agricultural practices.

尽管水污染开始受到应有的重视，但由于当前的农业实践对水质产生了前所未有的影响，因此农业的贡献需要得到更多的考虑。本文回顾了农业水污染（AWP）特定领域的知识，并确定了未来的研究需求。其中包括污染源归属，新出现的污染物，成本和采取减少污染措施的诱因。未来的研究重点包括识别和测试适合当地的标记；模拟污染物对生物群和微生物污染物传播途径的影响；协调国家和项目之间的AWP数据收集和经济成本计算；以及如何更好地分享相关知识以激励改进的农业实践。
