The Asian Development Bank (ADB) has developed a draft framework for its water operations that promotes public-private sector partnership in resolving the water crisis in the region.

In a statement issued Tuesday, the Manila-based lender said the Draft Water Operational Framework for 2011-2020 is focused on the efficient use of water resources such as advanced water-efficient irrigation practices, reducing losses in urban water supply systems, and the development and adoption of technologies that offer cost-effective ways to treat and reuse wastewater.

The framework also aims to encourage private companies to invest more in developing the water resources in the region.

"Increased investments from the private sector, especially in managing and delivering water services, and in using technology and innovation to reduce our water footprint will be critical to securing a sustainable water supply," Arjun Thapan, ADB's Special Senior Advisor, said in a statement.

Thapan said that Asia is an "inefficient water user." Most countries in the region have "a constant bias towards growing supply rather than managing demand."

The efficient use of water resources is important as urbanization, pollution, and competing demands for water for energy and food production reduced water stocks in many Asian countries.

Climate change, which can lead to extreme weather events, is also threatening the region's water resources. ADB estimates that by 2030, there will be a shortfall of 40 percent between water supplies and demand in the region.

The inefficient use of water is contributing to the impending shortage. Leakage in urban water supply systems alone amounts to the loss of as much as 29 billion cubic meters a year, valued at US$9 billion.

Thapan, who also serves as convener of this week's international water conference, said ADB's draft Water Operational Framework proposes a new paradigm for developing countries, spurring them to "focus on efficiency gains, business-like approaches, and effective partnerships to make better use of scarce resources."

The framework -- drafted in consultation with stakeholders -- will serve as a guide for ADB's work in the water area.

The framework recommends a study to examine the outlook for available sources of freshwater in the region over the next 20 years. It will also forecast the impact of water use policies and practices on food, energy production, industrial growth and domestic use. The framework will also consider potential technology solutions to improve efficiency, and business models to encourage private sector investment.
