NAGOYA — The World Bank said Thursday in Nagoya it will begin a project to help developing countries integrate the economic benefits of nature into their state policies in an effort to save millions of people from poverty while making sure their natural assets are used in a sustainable way.

Introducing ecosystem valuation into national accounting systems will help governments make better decisions about the way their nature is managed, World Bank Group President Robert Zoellick said in Nagoya, where he is attending the Convention on Biological Diversity meeting.

"We need to give top decision-makers the tools they need to make the right decisions," said Zoellick, the first World Bank Group president to attend the biodiversity meetings.
