Changes

In many developing countries, transfers remain a major source of financing for sanitation and drinking-water, most for [[Capital Expenditure (CapEx)|capital expenditure]] (GLAAS, 2012). Over US$ 8.9 billion in official development assistance (ODA), part of transfers, was directed to sanitation and drinking-water in 2009 (GLAAS, 2012). It accounts for more than 1% of Gross Domestic Product (GDP) in seven developing countries (see table 1).
