抗擊500年來最嚴(yán)重的干旱,,看美國加州如何用新技術(shù)節(jié)水

????布里斯克說,,與金融投資一樣,,擁有多元化的水資源“資產(chǎn)組合”很重要。水量充足的時候可以使用廉價的水源,;較為昂貴的水源則可以在困難時期維系一個地區(qū)的用水,。

????布里斯克將成功治理旱情的澳大利亞作為例證。該國推出了一個全新的水資源期貨交易所,。他說:“他們擁有一整套非常靈活的機(jī)制,,能夠充分體現(xiàn)水的利用價值。一旦水資源擁有這種價值之后,,對于新技術(shù)的巨大需求就會顯現(xiàn)出來,。而這一機(jī)制的信息和技術(shù)密集度也會越來越高?!?/p>

????他解釋道,,“我們在試圖提供一條市場化道路,。我們有很多卓越的技術(shù),只是它們沒有被市場利用而已,。為了接觸那些能將新業(yè)務(wù)模式引入這一領(lǐng)域的人士,,公司投入了很多的精力,而新業(yè)務(wù)模式與新技術(shù)的重要性幾乎是不相上下的,?!保ㄘ敻恢形木W(wǎng))

????‘We’re trying to offer a path to market’

????To make an impact in drought conditions, “there are two legs you have to walk on,” said John Briscoe, a professor of environmental engineering and environmental health at Harvard University and the director of the Harvard Water Security Initiative.

????“First, you have to have infrastructure,” Briscoe explains. “Second, you have to have institutions”—that is, rules and organizations to govern the effective management of water.

????As in financial investing, it is important to have a diverse “portfolio” of water sources, Briscoe says. Cheaper ones can be used when water is plentiful; more expensive ones can sustain an area during difficult conditions.

????Briscoe points to Australia, home of a new futures exchange focused on water, for its success dealing with drought. “They have a very flexible set of institutions with very clear signals about the value of water use,” he says. “Once water has this value, there’s a huge call for new technology. It becomes more information- and technology-intensive.”

????Globally, the water market is worth roughly half a trillion dollars per year, says Scott Bryan, chief operating officer at the clean water nonprofit Imagine H2O. “If you look at the magnitude of the ecological and humanitarian need plus the market need, why don’t we have more entrepreneurs and investors looking into this issue?” Bryan asks. Even in California itself, “very little of the tech boom focuses on our region’s most pressing issue,” he adds.

????For the last five years, Bryan’s firm has offered an annual business innovation competition through which early stage entrepreneurs and researchers can submit their ideas for judging by a panel of venture capitalists and other experts. It then gives the top 12 contenders a place in its accelerator program. “Our winners and finalists now represent one in every six dollars of early stage financing in the water sector,” Bryan says.

????“What we’re trying to offer is a path to market,” he explains. “We have a lot of great technology out there, it just doesn’t make it to market. A lot of our work is reaching out to people who can bring new business models to the sector—that’s almost more important than new technology.”
