The availability of freshwater is limited for agriculture systems across the globe. A fast-growing population demands need to enhance the food grain production from a limited natural resources. Therefore, researchers and policymakers have been emphasized on the production potential of agricultural crops in a sustainable manner. On the challenging side, freshwater bodies are shrinking with the pace of time further limiting crop production. Poor-quality water may be a good alternative for fresh water in water scarce areas. It should not contain toxic pollutants beyond certain critical levels. Unfortunately, such critical limits for different pollutants as well as permissible quality parameters for different wastewater types are lacking or poorly addressed. Marginal quality water and industrial effluent used in crop production should be treated prior to application in crop field. Hence, safe reuse of wastewater for cultivation of food material is necessary to fulfil the demands of growing population across the globe in the changing scenario of climate.
全球农业系统的淡水资源供应有限。快速增长的人口需要从有限的自然资源中提高粮食产量。因此，研究人员和政策制定者一直强调以可持续的方式提高农作物的生产潜力。具有挑战性的是，随着时间的推移，淡水体正在萎缩，进一步限制了作物产量。在缺水地区，劣质水可能是淡水的一个不错替代品。它所含的有毒污染物不应超过某些临界水平。不幸的是，缺乏针对不同污染物的此类临界限值以及不同废水类型的允许质量参数，或者对此处理不当。用于作物生产的边际质量水和工业废水在应用于农田之前应进行处理。因此，在气候变化的背景下，为满足全球不断增长的人口需求，安全回用废水进行粮食作物种植是必要的。
