Critics claim that maize can cause unwanted environmental impacts. But supporters of the crop are able to show how by use of cover crops it can be grown responsibly, reducing or eliminating, for example, nutrient leaching and soil erosion. In south-west England, a Wessex Water project is using cover crops to protect and improve drinking water quality by working with growers whose farms surround boreholes and reservoirs that supply water for human consumption. Steps like this can contribute to SDG 6 to ensure sustainable management of water and SDG 12 to ensure sustainable production.
The RELX Group Environmental Challenge is awarded annually to projects that best demonstrate how they can provide sustainable access to safe water where it is presently at risk and/or access to improved sanitation. The 2016 winner was Loowatt - an innovative sanitation solution which also generates power. The Environmental Challenge directly assists SDG 6.1 and 6.2 to achieve universal and equitable access to safe and affordable drinking water and access to adequate and equitable sanitation and hygiene, for all.
