In response to the publication of the new Lancet Series on Maternal and Child Nutrition, Margaret Batty, WaterAid's Director of Policy and Campaigns said: "The impact of undernutrition on millions of children globally is devastating. The new Lancet series shows that tackling the problem will require coordinated efforts across many organisations and strands of work." "With the World Health Organisation estimating that half of malnutrition cases are associated with diseases or parasites caused by lack of safe water and adequate sanitation and hygiene, we believe that efforts to increase access to these services must be a vital part of efforts to improve nutrition." "But beyond the direct disease link, access to water, sanitation and hygiene services affects, among other things, women's education and empowerment, which also impacts on their nutrition and that of their children." "We hope that the 'Nutrition for Growth' summit this weekend will recognise these links and set the scene for more effective efforts to improve nutrition."
