FRESH water is one of our most vital resources, but some nations have much greater access to it than others. That is partly down to the geographical good fortune of being sited upstream on a great river. But it is also because there is no functioning international treaty governing the sharing of transboundary waterways. In the age of mega-dams, downstream countries get water at the whim of their upstream neighbours.
There should be a treaty. The was signed 15 years ago. It required countries to ensure the sustainable and equitable use of shared rivers. At the time, only three countries 鈥� China, Turkey and Burundi 鈥� voted against. All three are upstream countries on major rivers. But despite this apparent assent, only 24 nations have subsequently ratified it, 11 short of the threshold that would bring it into force.
Some countries鈥� reluctance to ratify the treaty is laughable. When questioned three years ago, the UK government claimed it did not want to 鈥渂urden partner countries鈥�, though it did not say who those partner countries were or how ratification would burden them. At least , arguing that it has 鈥渋ndisputable territorial sovereignty over those parts of international watercourses that flow through its territory鈥�.

This week, we report escalating concern about China鈥檚 bullying tactics over five mighty rivers flowing out of Tibet, upon which downstream countries including Bangladesh, Cambodia and Vietnam depend (see 鈥淐hina is taking control of Asia鈥檚 water tower鈥�). There are many other festering disputes, including on the Nile, Tigris and Euphrates. We also reported recently on a proposed dam on the Guinea stretch of the Niger river, which threatens vital wetlands in downstream Mali (New 杏吧原创, 24 March, p 9).
Almost half the world鈥檚 people depend on water flowing down international rivers. Yet two-thirds of those rivers have no water-sharing agreements. This is a scandal that June鈥檚 Earth Summit in Rio should address. It should call for rapid ratification of the UN treaty. The world鈥檚 water bullies need to be tamed.
