Cotton also has a reputation as a water-intensive crop, and questions have been raised about the efficiency of water extracted for flood irrigation, water quality concerns such as pesticide run-off into groundwater, and water scarcity in relation to water availability.
Furthermore, consumers are highly sensitive to water and pesticide usage in cotton production [6].
One figure from the World Wildlife Fund (WWF) [38] states that it takes up to 2700 litres of water to produce a cotton t-shirt.
Another claim, from the Textile Exchange [39] report, suggested that organic cotton uses 91% less blue water consumption than conventional cotton.
