Celebrating World Water Day, The Lancet Editors1 highlighted the gains made towards Millennium Development Goal (MDG) 7c, “to halve, by 2015, the proportion of the population without sustainable access to safe drinking water and basic sanitation”, and noted UN-Water's call for sustainable water management in view of future increases in demand and shortfalls in supply. As the primary water collectors worldwide, women are disproportionately affected by the scarcity of adequate resources; however, global estimates of improvements in water access do not reflect gender-disaggregated benefits and burdens.
