Aral Sea Disappearing
W33dz writes "The BBC is reporting today that the Aral Sea on the border of the former Soviet republics of Uzbekistan and Kazakhstan has lost half its size and 75% of its volume in the last 15 years. The article includes some stunning pictures from both NASA and the new European Space Agency's Envisat satellite.
This seems especially poignant since the US Government is hosting a summit on a proposed International Earth Observation System in Washington this month (BBC article). The meeting is intended to defend much of the Bush Administration's environmental policy and has an amazing guest list filled with the Who's Who of US politics."
Dissappearance, why stop it? There's a lot of things we dont know about nature and ecological climates.
For all we know, this could be based on the 13000 year cycle of the earth.
It's due to excessive draw on the rivers that feed the sea for irrigation. According to the article, the much of the water is actually wasted due to poor-quality irrigation systems.
Oh Oh...editor didn't check the first link!
What does Bush or his policies have to do with a sea in Asia that started to disappear 10 years before he came to office?
I know that people will post comments saying the Bush administration is trying to protect big business in the U.S. and doesn't want the bottom line hurt but has anyone considered that these less developed nations who are pushing for new regulations to be imposed want to see developed nations crippled and therefore the wealth they have redistributed to the rest of the world? Politicians the world over are usually most interested in the money issue - not the earth issues. So, more study is always a good thing, in my opinion. Has any scientist come out and said if we do not start changing things now, in ten years everyone will be dead or in ten years things will be so bad they won't be able to be fixed?
I hate liberals. If you are a liberal, do not reply.
If the border between Uzbekistan and Kazakhstan is disappearing, then at the point when it is gone, what sort of war will ensue in an attempt to claim the land? 75% in 15 years is a lot. It should be completely dissipated soon.
Where/How will the border be defined?
I recall watching a documentary on a Soviet-era facility dedicated to researching and developing bioweapons. As of the late '90s, there were massive stores of anthrax and smallpox buried there, and some of it was leaking.
They mentioned that the sea was shrinking, and that would make it easy for animal life to transfer the deadly pathogens to the mainland.
Or make it easier for the terrorist bad guys to get their hands on it.
I think this is a bad thing all around.
no thanks
Errr, not to nitpick but the Soviet governments that were responsible for the disastrous irrigation projects in Central Asia were led by Nikita Khrushchev and Leonid Brezhnev. The current Bush administration had very little to do with it.
What I'm listening to now on Pandora...
I watched a video about this in a Political Science class that I had to take. In the video, they showed places that used to be shipping piers that are now desert. The video also stated that 80% of the feeder rivers' water is lost due to evaporation in inefficient irrigation canals.

More than enough BS
If anything, the Aral Sea situation shows that these issues are not as simple as environmental extremists would like to make them out to be. Farmers need water. As the article says, their irrigation systems are not efficient, but who will pay for a new one? Perhaps the farmers should be made to pay for such a system, and maybe they should even compensate the fishermen who have lost their livelihoods. But answers that are acceptable to all sides are not so no-brainer obvious.
A lot is made of the "leaky irrigation" and such, but that makes no sense. Is the irrigation surrounding the rivers taking the water out of the sea's watershed? Seems unlikely. The water would just eventually run back into the river and the sea. I mean, how is water leaking from a poorly-built irrigation system different from the rain that falls right next to it and feeds the rivers and the sea to begin with? This reeks of sensationalism. There may be a real environmental problem here, but "leaky irrigation" is a red herring.
Nonperiodic Central Trajectory
Just to clarify and emphasize why this is a big deal: Aral is not really a sea - it's a lake. A sea is a body of water that has direct exit into an ocean. A lake - doesn't connect to any ocean. Aral Lake is the second largest lake in the world - the first on is Caspian. Both of them are usually referred to as Sea because of their great size.
Just because I don't care, it doesn't mean I don't understand. Homer J. Simpson
I remember seeing stories about this back in 1985, for fuqs sake. Back then, more than half of the sea had already dissapeared because of mismanagement by the Soviet government. I've seen several referneces to it since then. If I recall correctly, that first story was from National Geographic, but that was a looong time ago, so don't hold me to that.
Life is hard, and the world is cruel
In other news, the largest freshwater lake in the United States west of the Mississippi no longer exists.
Life's tough. Without the death of Lake Tulare, California would produce far less crops to feed the world. Without the Three Gorges Dam, China would have to build lots of fossil fuel or nuke plants.
It's always bad when we lose a valuable and unique ecosystem like the Aral Sea, but sometimes we humans must make tradeoffs. I have no clue whether the death of the Aral is an appropriate one, but I think we should not presume that the Aral's death is all bad. For example, do more people get fed by selling irrigated cotton that would have been fed by fishing?
"ust to clarify and emphasize why this is a big deal: Aral is not really a sea - it's a lake. A sea is a body of water that has direct exit into an ocean. A lake - doesn't connect to any ocean"
huh? It is a sea, primarily because it is salty.
The vast majority of what is called lakes do connect to the ocean: from Lake Superior to Lake Placid.
See dictionary.com concerning sea " A relatively large body of salt water completely or partially enclosed by land." This applies to the Caspian Sea as well. Lake Superior is the largest lake in the world, not the Caspian Sea.

This was when George W Bush was working for his dad on a secret CIA project back in 1986.
Not wanting to commit things to paper and have them get out through the Freedom of Information Act, the planning went around by word of mouth. Dick Cheney (fresh back from a mission to pollute the canals on Mars) wanted to tell Bush Jr over the phone to get rid of the CCCP (Russian acronym for USSR).
However, the phone cut off mid-conversation, and all Bush could hear Cheney say was "About Russia? I want you to get rid of the C..."
Bush took this partial instruction literally, and proceeded to eliminate the smaller of Russia's internal salt seas.
Don't blame Durga. I voted for Centauri.
What was that again? Johnson rises to defend Dick's honor?
The largest freshwater lakes in the United States west of the Mississippi (Lake Powell and Lake Mead) are there because of irrigation needs, as are a wide variety of other lakes created by dams on rivers and streams all over the country.
Don't blame Durga. I voted for Centauri.
The Central US will be running out of water in the next 50 to 100 years because of irrigation. Right now, farmers from Texas to the Dakotas get their water from deep aquifers. The problem is that these aquifers were filled by meltwater from the last ice age and are no longer being replenished. Within the next 50 to 100 years, that water will be gone. Plans are already being discussed to divert the Missouri, Mississippi, and Arkansas rivers so that their waters can be used to continue irrigation in America's breadbasket. This could have devistating effects on water supplies and ecosystems downstream.

...compared to the 1000 miles of streams that have been buried in West Virginia. Not to mention the 15%-25% of southern West Virginia's mountains that have been leveled causing the loss of 300,000 acres of highly productive hardwood forests.
All so you can have electricity for 3 cents per kilowatt-hour.
- Hail to our fearless misleader! Fool speed ahead!
We're going to divert rivers. We're going to alter the natural habitats of pretty much all life on the planet. Animal species will go extinct (unless we take the time to specifically preserve each and every one). We're going to change the mixture of gases in the air...
At some point, everyone is going to have to come to grips with this. The Earth can't support this many people and still exist in it's "Natural" state. The hard part is not screwing it totally up and ending up with a toxic environment.
Eventually, the land's all going to be either populated area (city / suburb), agricultural, or a managed wildlife "park".
Go to Google and search on
"aral sea" saltwater.
You will see many references to it being a saltwater sea, including Encyclopedia Brittanica, The Aral Sea Homepage, and a wide variety of geographical and educational pages.

How did they make the desert bloom?
The most important innovation in coping with scarce water supplies has been drip irrigation. This method of irrigation applies water and nutrients directly to the root of the plant at a controlled rate. See the drip irrigation pipelines. With traditional irrigation, most of the water evaporates from the ditch and is wasted. Drip irrigation uses less water, works with saline water, requires less fertilizer, and produces more crops.
It was invented in 1965 and has been used all over the world. If those former Soviet republics aren't using it, I suspect the reason is that they don't think they can afford to pay for the equipment. I would say that perhaps they can't afford not to pay for it.
In soviet russia, lakes disappear you!
You think wars for oil are bad?
Wait until there are wars for water.
People can live without oil. They may not want to (what would happen to the US without oil?), but they can. Water, however, is a different story.
I've seen an incredible number of stories about water, water shortages, fights over water rights and irrigation, and such in the past year. As the population of the Earth continues to rise, so does the demand for water. Many of the water supplies currently being used are already being used faster than they can replenish - and they're only going to get more use.
Eventually areas are going to start having serious water shortages.
The most wasteful country in the world in terms of water? No suprise, the US. The combination of all the endless golf courses, which is the #1 use of water in the US IIRC, and all those suburban laws, especially in areas they're not supposed to be growing such as the Southwest, and incredible amounts of water are being taken from rivers and aquifers for pretty silly purposes.
I wonder how long until serious money starts being spent on how to make cost efficient desalinization of ocean water, and better pumping to get the water from coasts to inland. Because there aren't going to be enough sources elsewhere to supply all the water needs at the rate things are going.
So much water on the planet, and still there seems to not be enough...
"You know your god is man-made when he hates all the same people you do."
It can't be that big of a deal.. the water has to go someplace.. water doesn't really leave the water cycle it just moves around.. I'm sure an ocean someplace just got 1/16 of an inch deeper or something.
The Aral sea used to be the 4th largest lake in the world. (Quick quiz: name the top 3.) It's now the 12th largest. (Slower quiz: name the intervening 8.)
Not only has it lost half its surface area since 1985, it seems to have lost two thirds since 1960. outlines are interesting. I wonder what it's like on that island that's almost a peninsula.
And while this has little to do with global warming, it's a prescient example of significant human-caused environmental change.
Ceci n'est pas une signature.
this book might be interesting to some of you who are interested in climate change and the changes in ecosystems, 2030 by Hunter (co-founder of greenpeace) is a wake up call if nothing more, while it may be slightly blown out of proportion it still gives a basic overview of the problems and what may be yet to come
I guess once every 13000 years two countries might actually share....

Insert Signature Here
I was taught this in school 7 years ago.
I've heard of these things called analogies. It's where one thing being like another in some aspect, is used as a basis for describing another aspect. Certainly, without any sort of indepth careful investigation they aren't much, but they aren't unknown in the world either.
Wastful management of resources in and around the aral sea are causing its disappearence because of the faulty assumption that it was too vast for the sum of human activity to have a significant impact. In this light, it is very much like the administration's philosophy reguarding how the vast American resources should be managed. (Off shore drilling, artic drilling, the great wastelands periodically created in the gulf of mexico off louisiana, single hulled oil vessels being permitted in puget sound, fuel efficency standards, tax credits for early adoptors of clean alternative energy (which Bush the sequel derided as part of his campaign and his father took advantage of), mexico's water debt, blah blah blah.) The argument put forth, admittedly on tenious grounds, isn't that Bush Mk ][ vaporized a soviet sea, but rather we will see similar rewards of his stewardship because of the kindred outlook, and same faulty assumptions.
However, regardless of how good the irrigation methods, it was my understanding that all irrigation eventually desroys the soil through salinization. "Better" irrigation methods merely reducing either or both the rate at which salinization occurs and the rate at which water is wasted through evaporation.
How efficient is hydroponics in contrast? It or other more or less closed methods would be useful in farming extreme climates such as underground or space.
Beta is broken and the link to classic doesn't work. Stop wasting our time or there won't be anybody left here.
Nothing to do with the U.S., "Global Warming" or the Kyoto treaty? Why bother? Unfortunately since this has everything to do with local squandering of water resources, nobody is interested railing against a bunch of local farmers or thirsty populace. Why even post an eco disaster story that so obviously is not the U.S.' fault and even worse point it out in the story. You should have waited for Reuters or the BBC to do a hatchet job on the story, distort the facts, & quote some anti-U.S. bigot to spice it up & blame it all on Bush before you posted this. Come on don't you even know how junk science and ecco-bunkum are supposed to be used to advance an adgenda?
Reading over the original post, the only link made between the lake's drying up and the Bush administration is that its "especially poignant" considering the recent debate over Bush's environmental policy. That's hardly trying to pin the blame on Bush, and people who reach this conclusion are reading far more than what's really there.
The Aral Sea's disappearance serves as warning to how much damage poor farming techniques and industry can do to the environment. As previous posts have stated, water resources are still being squandered at an alarming rate all over the world, and governments and industry should start taking precautions.
This isn't really a trade off between "natural ecosystems" and supporting the population; if the farmers around the Aral Sea are poor now, just wait until the watershed is depleted beyond use.
On-Topic Portion: This is a good justification for the space agencies' continued investigation into environmental problems on earth.
The sending of this message pretty much inconveniences everyone involved.
Having written the oringal post, I need to clarify that I was only pointing out the irony of Mr. Bush hosting an environmental summitt while his government's policies are so obviously ambivalent to the environment. Remember, this is the man who refused to even consider the Kyoto treaty and has opened up MILLIONS of acres of federal land to oil and timber companies. He and many in his administration are ex-oil executives. They made their livelihoods in petrochemicals and are not going to stop now. This is not saying that he is evil. . .it is saying that we need to pay attention to what he does not what he says.
We are Pentium of Borg. Division is futile. You will be approximated.
In a moving river, the water shallow and warmed by the sun, but in a large resevoir, it get's cold. The river water temp is therefore much colder downstream of the dam which screws with the wildlife.
Too bad Mexico can't sue the US over taking all the water before it gets to the ocean though...
Eat at Joe's.
hehehe
Though now, I bet if you lived next to the stinky rotten fish and brine shrimp salt lake, you couldn't wait for it to go away. I wonder who owns the land after a lake dries up?
Eat at Joe's.
This is not meant to be flamebait, I really think this, but whatever..
The fact is that the human race will not stop raping the environment until it's unconsious or dead. Only when the environment is so badly damaged that human beings can not reproduce fast enough to replace all those that die of starvation and cancer will the environmental impact caused by humans really let up a little.
From then on, we'll still take as much as we can which will never be enough.
Why is this true? Because we can not help ourselves. We are alive. As such we are bound to do as best for ourselves as we can, and make as many offspring as we think we can raise to adulthood. If there are some humans who would be 'altruistic' and sacrifice time/energy for the environment's sake then that is just more resources for the rest. If there are some people who would limit their own reproduction - for any reason be it altruism or merely because they want to have enough time/money for each child, they will eventually be bred out of existance by the welfare queens and deadbeat dads that make babies with them.
Watch the Jerry Springer show. That is the future, past and present of the human race. Anybody with 'dignity' is not playing the game.
A mouse does not think about the environment. It accepts it and does it's mousely best. That not optional over generations. Nature demands it of the ancestors of any lifeform. No lifeform exists on earth now whose ancestors did not live up to that mandate and none ever will.
In short we'll never stop raping Mother Nature, because she's a whore who likes it, and She's in charge.
Eat at Joe's.
There's a long section in the Economist about two weeks ago on the Central Asian Republics with one article that talks about the politics of water there. The Aral Sea is drying up because the irrigations systems of the countries along the rivers that feed it are horrendously inefficient, and because the water system as a whole in the region is poorly managed. Unfortunately, with one megalomaniacal ruler in Turkmenistan, and a whole host of other political solipsists in the region, this isn't likely to change in the near future.
The island in the Aral Sea, Vozrozhdeniya Island, (which incidentally means something like "rebirth" or "revival") was the test site for Russia's expansive bioweapons program.
Think it through - island inhabited by all manner of animal life, and stocked with certain animal life, and this animal life and environment repeatedly blasted year after year with a variety of biological weapons, and the results recorded. What survived, what didn't. Et cetera.
Now, this island is becoming/has become a peninsula so that things can freely wander on and off the island at will.
So from the history books - Many indigenous peoples were wiped out due to a lack of immunity to the influx of disease brought by travellers (among other things - but that is off topic).
What is going to happen to the rest of us when all this badness escapes Vozrozhdeniya Island ?
One dollar to the person who connects this event (island to peninsula) with monkey pox.

Read Ken Alibek's _Biohazard_ for more information. He is one of the former heads of the Soviet bioweapons program who defected back in the late 80s/early 90s.
No.
Where does a developing nation get its wealth? From trade. Weakening the developed countries means they have less money that can be used to buy whatever it is developing countries have to sell, and a side effect is weakening the currencies of developed countries so the manufactured goods and high-level services they can't make for themselves become even more expensive for them.
To use my favorite Ferrengi question, "Where is the profit?"

Not surprising, most of us don't consider Rush Limbaugh and Monsanto and White House spokesdroids as "Men of Science".
Tech Public Policy stuff
I can go into a tobacconist's shop and purchase enough electricity to heat and light my home for two weeks. This much power can be storted on a little plastic key about 6cm. long by 1.5cm. by 0.5cm, and released slowly by the electric meter under the stairs. Furthermore, it is an alternating current {and they said you couldn't store AC!} of 230V and up to several tens of amperes - yet rigidly fixed at exactly 50 cycles a second. No measuring instrument I have encountered can detect the error. Yet, this little plastic key is safely insulated, lest this raw, dangerous energy should find a way to leak into my pocket, for example.
So why can't they adapt this technology to give us all cheap, clean, safe electric cars?
Now, if you want to defend the shrub's pollution policies, there's some chance of success.
If the Aral Sea's bed was not a windswept wasteland of toxic, radioactive, and teratogenic compounds that will pose a danger to local citizenry for a thousand years, there would be no border dispute.
This is not exactly news... the problem was well documented before the collapse of the Soviet Union, after all.
Yes, but it does so just over the border in Mexico, so no one cares. The Colorado delta is a wasteland rivaling the Aral Sea.
an ill wind that blows no good
