Henk Ovink, Special Envoy for International Water Affairs for the Kingdom of the Netherlands, referred to the Blue Marble planet of which 71 percent is oceans, and yet only 0.4% can be used. “It looks like there is an abundance of water, but it is actually very scarce,” he said. “We have to manage water on every scale much better than we do now,” said Ovink, summing up the take-home message of the conference.
