CURRENT STATE OF WASTEWATER USE IN IRRIGATED AGRICULTURE
Due to climate change, the areas affected by drought and water scarcity are increasing rapidly. Thus, wastewater has become a valuable resource to the farmers because it is a consistently available source of irrigation water. At least 10% of global population consumes food fromwastewater irrigation and over 20 million hectares (10% of irrigated land) are irrigated with untreated, partially treated / diluted or treated wastewater. More than 200 million farmers in 44 countries recover 15 million m3 of treated wastewater / day for irrigation. Although in many countries there are no regulations on the quality for irrigated wastewater, there has been growing interest in the long-term effects of wastewater irrigation on human health and the environment.
