很优秀的帖子。我只是偶然看到你的网站,并且我希望说,我真的很喜欢阅读您的博客文章。
詹姆斯•沃克曼和蒙哥马利•赛蒙斯认为,水资源短缺不仅限制着中国的经济增长以及城市化进程,还使危机进一步加剧。他们分四部分对水资源的价值这个在保护水资源过程中需要克服的第一个挑战进行了探讨。

我真的很享受阅读这篇有见地的文章。我二十四岁,因此我属于I 人口(I demographic).为了寻找健全的能源政策并逆转资源耗尽的危险,我们需要付出极大努力。但中国引人关注的消费增长趋势,却令我十分担忧。我相信Garret Hardin的研讨会文章《公地悲剧》应当作为中学的必读文选。我们需要缩小国际环境教育之间的鸿沟。我认为中外对话是一个极好的例子,并觉得类似的措施应能得以在更大范围内实施。随着视频会议以及网上论坛的兴起,我想看到世界领导者们在环境教育项目上合作,能让孩子们聚在一起讨论他们的未来。另一件事,国家地理曾在去年冬日举行过一个以“70亿人口”为主题的节目,其中有精彩的图表以及模型,若是你对这个主题感兴趣不妨一看。我曾和其他中国年轻人在新浪微博上讨论70亿人口的问题。我很高兴看到社会媒体将人们聚在一起,让人们关注影响我们所有人的重大议题。

I really enjoyed reading this comprehensive article. I'm 24 so I'm part of l demographic that will have to fight hard to reverse resource exploitation and seek sound energy policy. What worries me greatly however is the growing trend of conspicuous consumption in China. I believe Garret Hardin's seminal work "Tragedy of the Commons" should be required reading in high schools. We need to bridge the gaps of international environmental education. I think 中外对话 is an excellent example of the measures that needed to be expanded to a much larger scale. With video-conferencing and internet forums so popular these days, I'd like to see world leaders collaborate on environmental education programs that will bring children together to talk about their future. On another note, National Geographic had a fantastic "7 billion" themed issue last winter which has some fantastic graphs maps and models for those interested in this topic. I had a good discussion with other Chinese in their 20s about the 7 billion issue on the Sina Weibo social media site and glad to see social media being used to bring people together on issues that impact us all!

我并不是唯一督促美国检察官对故意煽动CO2气候变化危机恐慌的IPCC的科学家和媒体的新闻编辑兴师问罪的前气候变化信徒。气候变化危机跟可持续性无关。25年前二氧化碳对亿万儿童的死亡威胁到现在也没有发生。现在是谁使美国的新保守主义共和党恐惧呢?布什让伊拉克战争的谎言和恐惧散播;现在奥巴马有了他自己的理由(气候变化危机),虽然他并没有在他的最后一个国情咨文中提到“危机”

I'm not the only former believer urging American prosecutors to lay criminal chargers to the leading IPCC scientists and media news editors for knowingly inciting this needless panic of CO2 climate crisis. Climate Change Crisis wasn’t sustainability. It was a 25 year old failed CO2 death threat to billions of children. Now who’s the fear mongering American neocon Republican? Bush had is Iraq War of lies and fear mongering, now Oboma has his, although he never even mentioned the “crisis” in his last state of the union address.

To fully understand the Euphrates conflict, it would be best to first have a look at my humble work entitled "The Middle East, War for Water" (enlarged edition), chapter 9, pages 211-244 and chapter 5, pages 87-92.

我很欣赏你的文章,特别是奥尔多·利奥波德的引文。但是你在描述浪费水资源的时候用了“愚蠢”一词,我觉得这样既不负责任又不正确。浪费水资源这个问题全球各地都在发生,这当然和人们管理不善有关,但问题的征结是:(一)人们(从小开始)缺乏环保教育及(二)资质差的政治领袖不愿意或者根本没有能力去实行有效的措施来限制发展水源短缺的地区或者提高水的价格。

I appreciate your article, especially the Aldo Leopold quotes. I think the use of the word "stupid" though, in your description of the depletion of water resources, is irresponsible and inaccurate. This depletion occurring internationally is, of course, due to human mismanagement. The problem lies in: (1) the lack of environmental education (from a young age) and (2) poor political leaders unwilling/incapable of making pivotal moves to restrict development in water-scarce areas and/or to increase water prices.

对于节约这件事情的研究,我们还不是很多。这篇文章为我们提供了一个楷模,那就是,美国人说的不总是对的,至少是理论上如此。美国,最为全球最先进,也是最先开展public utility管制的国家,各州以及各县的管制情况应该是千差万别,所以呢,中国读者不用为美国这么多的自来水公司感到吃惊。
自来水行业呢,实际上是垄断性比较小的行业,绝大多数都是地区性质的小企业,这也难怪美国那么多的水公司。相反,电力行业的集中度就很高,目前在美国大约有3600多个电力公司。所以,本文上来就说自来水公司这种自然垄断实际上是不很合适。另外,按照美国著名的托梅因教授(Professor Joseph Tomain)的意见,垄断最主要的特征是随着规模的扩大,或者营业额的提高,成本会自然下降,这实际上是对消费者有好处的。当然了,前提是,政府要“管得住”,公用事业公司的财务要透明,要接受监督,要民主参与才行。
关于这位女士遇到的问题,我在想象中也遇到过。我认为实际上这不是问题的“问题”。因为,对水的需求侧管理实际上呢,在加州以及很多地方开展的很多,成效也很大。关键在于市政当局的参与,而不是像这位女士这样的,孤军奋战。作为公用事业单位,首先部位盈利为主要目的,主要目的在于提供公众服务,也就是纳税人的钱为自己服务,为了吸引投资人,一般也会为这样的业务提供一个相对有吸引力的投资回报率,在中国一般是年回报率4-5%左右。别忘了,这些所有的投资以及回报最主要的目的是为公众服务。那么,如果用水量持续下降,那么为了取得必须的、受到法律保护的投资回报,就需要提高水价,以便实现财务平衡或者取得预设之盈利目标。这在电力行业很普遍,不足为奇。或者说到底,就需要把水公司的盈利部分或者全部和营业额脱钩,英语叫做decoupling。
回到这位女士的问题,很遗憾她是个好人,但是好人并不一定就做得了好事,因为这不是她的个人努力就能实现的事情。简单来说,这说明这个女士的公司没有一个明确的营业战略,特别是从节水的角度来说。这也很可能说明,当地政府对节水还停留在表面状态,一点也没有深入下去, 和我们中国的情况类似。如何做呢,我可以在下一篇中解释。

We have done very little study on saving. This article has provided an example that what Americans say is not always right, at least in theory. The US, the most advanced country on earth, which is also the ealiest to implement public utility regulations. There must be much difference in regulations among states and counties given various different situations. Therefore, Chinese readers shouldn't be surprised that there are so many water companies in the US.
In fact there is relatively low level of monopoly in water industry. Most of water utilities are small regional firms. So no wonder there are so many water companies in the US. On the contrary, the level of concentration is high in electricity industry. At present, there are over 3600 electricity companies. Therefore, it is not appropriate that the article started by saying that water companies have natural monopoly. In addition, accoding to the renowned Aemrican Prof. Joseph Tomain, the most important nature of monopoly is that the costs would decrease with the expansion of the scale or the increase of the revenue, which would benefit comsumers. Of course, the assumption is that the government is able to "control" and the untilitles's financials have to be transparent and are monitored by public.
I imagined that problems encountered by this lady mentioned in the article. I don't think these problems are actual issues. Because the water demand management is actually implemented in many places including California with remarkable achievements. The key to success is to involve authourities, not to fight alone like the way that lady did. The utitlies as a company is focused on profit, providing a public service, ie, serve the taxpayers with their own money. In order to attract investors, a reasonable investment return has to be in place. In China, the annual return is about 4-5%. Don't forget, the overriding purpose of the investment is provide a public service. If the water consumption is declining, it's necessary to increase water rates so as to reaslise the profit target or financial balance in order to achieve the necessary investment returns set out by law. It is the common place within elelctricity industry. The bottum line is that the profit of a water company should be partially or entirely decoupled with the revenue.
Go back to the lady's problems. She is a good person. Unfortunately the fact is that being a good person doesn't mean that good deed can get done as the deed can not be accompolished by her indivivual effort only. Put it plainly, her company lacks a clear business strategy, especially from the water saving point of view. It is possible that the local government's water saving startegy is only at the superfacial level without diving itself deep down the issue, similar to situations in China.
I will explain how to tackle this next.
