Most ODA for water is committed by a small number of mainly bilateral donors. Among the 30 donors listed by the OECD (22 bilateral donors and 8 multilateral, the top four donors provided more than 60% of the ODA for water between 2000 and 2004, and the top eight provided more than 80%. Japan is by far the largest donor, providing approximately 25% of overall ODA allocated to the water sector. It thus has a great influence on the evolution of overall ODA for water. The other main donor countries are Germany, France, and the United-States.
Similarly, most ODA for water goes to a relatively small number of recipient countries. Between 2000 and 2004, 43% of ODA commitments for water were allocated to the top-10 recipient countries. China and India, large emerging countries, are among the three main recipient countries. Latin America and Sub-Saharan Africa feature little (except for Peru, Ghana, Tanzania and Mozambique).
