While the funding gap is vast, 147 countries have previously demonstrated the ability to mobilize the resources required to meet the Millennium Development Goal target of halving the proportion of people without an improved source of water, and 95 met the corresponding target for sanitation.

用于水和环境卫生的官方发展援助拨款（支出）在2012年至2015年从63亿美元增加到74亿美元。

Considering the greater needs to make progress towards universal access to safely managed WASH services under the SDG targets, the possibility of future reductions in aid disbursements is at odds with global aspirations.
