Investment in ecosystems will reap rewards: UNEP

From a Reuters article by Nina Chkestney:

LONDON (Reuters) - Nations that take into account natural resources in their investment strategies will have higher rates of return and stronger economies, a report backed by the United Nations' Environment Programme said on Friday.

With less than one month until a U.N. climate summit in Copenhagen, the report urges policymakers to reform their economic policies to stop the destruction of natural resources such as forests and oceans.

"Repairing the ecosystem by replanting forests, restoring mangroves along coastlines or rebuilding coral reefs are very smart ways of doing adaptation. People going into Copenhagen are not necessarily aware of these things," Pavan Sukhdev, the leader of the study prepared by UNEP's Economics of Ecosystems and Biodiversity Initiative, told Reuters.

For example, planting and protecting nearly 12,000 hectares of mangroves in Vietnam costs over $1 million but it saves over $7 million in dyke maintenance expenditure.

The report estimates that investment in mangrove and woodland restoration could achieve rates of return up to 40 percent, tropical forest investment up to 50 percent and grassland investment 79 percent.

"We studied the economics of using nature better -- through adaptation and restoration. In each case we found the benefits exceed the cost, typically between 3 and 75 times," Sukhdev said.
