Stephen has today lent his support to World Water Day. The day, which is organised by WaterAid is held to raise awareness of the importance of freshwater in the developing world. According to the UN, 783 million people around the world still lack access to clean water.
The day was initially recommended at the 1992 United Nations Conference on Environment and Development (UNCED) and the UN General Assembly designated 22 March 1993 as the first World Water Day.
Speaking about his involvement in the campaign Stephen said: "In recent years there has been real progress in reducing the number of people in developing countries that do not have access to clean water or sanitation. However, more needs to be done.
"The UN's High Level Panel on Post-2015 Development identified that achieving universal access to water and sanitation by 2030 as one of their 12 illustrative goals and targets. Governments must work together to widen access to basic utilities such as clean water and sanitation to ensure this vital target is met."
