The Environment and Human Rights (6): The World’s Water Supply

If all of the earth’s water – salt and fresh water – would be collected into a single sphere, it would be this big compared to the size of the Earth:

The sphere includes all the water in the oceans, seas, ice caps, lakes and rivers as well as groundwater, atmospheric water, and even the water in you, your dog, and your tomato plant.

A telling visualization of the world’s water crisis, albeit with a hint of alarmism, and an ideal occasion to link back to some of my older posts about the water crisis: here, here, here, here and here.

The Environment and Human Rights (4): A Right to Water

The United Nations General Assembly recently voted in favor of an international human right to water. It’s only appropriate that people have a right to the most basic resource. Only a few countries (e.g. South Africa) have already instituted this right. The recognition of this right of course doesn’t mean that the water crisis has magically disappeared. Like the right to free speech doesn’t mean that there’s no more censorship. The real work of bringing water to people who don’t have enough still needs to be done, and some serious thinking and debating is required. Opponents and proponents of privatization, of the introduction of a water market and of other possible policies (including the policy of setting water prices high enough to discourage waste and low enough to help the poor) will continue to disagree and it will have to be settled empirically which water policy provides the best access to all.

On the other hand, the water crisis seems to be abating:

some 5.9 billion people, or 87% of the world’s population, enjoyed access to drinking water from an “improved” source in 2008. In other words, those people had water piped to a dwelling, or got it from a public tap or a protected well. Back in 1990 only 77% of the world’s population enjoyed such a luxury. Yet in some parts of the world, notably in Africa, great improvements in water supply are still needed. Some 884m people are still not using an improved water source, more than a third of them in sub-Saharan Africa. Eastern Asia has seen the greatest recent progress: 89% of the population in that region now have access to an improved water source, up from just 69% in 1990. (source)
