  • The Amu Darya, in the west, and the Syr Darya, in
    the east
  • Their 600 tributaries take source in the Tien
    Shan and the Alai highlands.
  • They feed waterways on their way to the Aral Sea.
  • The rivers fall short of feeding the Sea properly
    to sustain it.
  • The desert has reclaimed a good portion of the
    Aral Sea and the rest struggles to survive.

Syr Darya
Amu Darya
The Syr Darya is formed by the confluence of the
Naryn and Qoradaryo rivers in the eastern
Ferghana Valley With a length of 1,374 miles
-1,876 miles including the Narynthe Syr Darya
is the longest river in Central Asia
The Amu Darya is formed by the junction of the
Vakhsh and Pandj rivers, which rise in the Pamir
Mts. of central Asia. Its length is 1,600 miles
long

Water and Pollution
  • Once the 4th biggest inland sea in the world
  • 53 Meters above sea level
  • Evaporation 60 square Kilometers of water each
    year
  • Environmental disaster
  • Large Controversy
  • Boron Pollution
  • Phenol Pollution

Agriculture
Simple Irrigation System
  • Upstream irrigation for the growing of rice and
    cotton consumed more than 90 of the natural flow
    of water from the Tien Shan mountains.
  • Sea Surface declined
  • 27,000 square kilometers of former sea bottom
    became dry surface
  • 60 of water volume was lost

7
Cotton
Cotton Harvest, Uzbekistan
  • Major Uzbekistan Crop
  • since Soviet era
  • Intense Agriculture
  • Pesticides
  • Intense Irrigation
  • Fertilizers

  • thriving environment until the 1960's
  • extensive irrigation schemes put in place
  • River water diverted from Tien Shan Mountains,
  • Would normally have flowed into the Aral sea
  • Huge amounts of this diverted water lay as
    stagnant pools across vast, badly managed cotton
    and rice fields. As a result the Aral has now
    lost more than 60 of its water.

Rice
  • South of the Aral Sea
  • Rice Paddy Fields are shown by the square boxes
  • This fields have a very high water portion.
    shown by Landsat Image
  • There are also artificial fishing ponds.
  • Usually filled in early spring helps to allow the
    fishing industry to survive.

Livelihood
  • Once a busy shipping trade between its northern
    port of Aralsk and the river ports of the
    Amu-Darya, some as distant as Tajikistan
  • Aralsk is now landlocked about 100 km from the
    water. It, like Muynak has fishing boats sitting
    high and dry on what was once the bottom of the
    Aral Sea.

The Changing Aral
13
Life blood
  • Once abundant fish resources
  • Once provided a livelihood for several hundred
    thousand people.
  • People living around those canals and using those
    waterways now depends on their existence--the
    very existence that sucks the life "blood" of the
    Aral.

14
Fishing Industry
  • 20 species of fish
  • Fish was based on three species of fishes bream,
    sazan, Aral roach (vobla). A very valuable fish -
    Aral barbal and white-eye were caught in the Aral
    Sea.
  • Located in coastal areas and rivers mouths.
  • Annual catching was 300-400 thousand centners
    (220.46 lbs) of fish.

Wastes
  • Shrinking steadily, adding to the desertification
    of the lakebed
  • Contamination of the region by exposing DDT,
    chemical pesticides, and natural salts.
  • Hazardous materials that are strewn about by
    wind, not only contaminate the food chain, water,
    and air but cause countless human health
    disorders.
  • A number of buried nuclear waste processing and
    chemical weapons sites that damage the soil.

17
Salinity
  • Salinity has increased from 10 grams/liter to
    40-50 grams/liter from 1960 to near present.
  • This is due to the lack of fresh water inflow
  • Drinking water in the region contains four times
    more salt per litre than the limit recommended by
    the World Health Organization

18
  • This figure shows areas where the environment in
    Uzbekistan and the surrounding areas have been
    severely degradated.
  • The impact of losing water has caused severe
    salinization

19
Salt Pans
The white large object on the left border of the
image is an artificial salt pan. Discharge water,
which is highly contaminated by salt
accumulation, is diverted into such pans in order
to decrease soil salinity. From these pans the
water evaporates totally unused and creates
salt crusts and olonchaks.

Climate Effects
  • Drier shorter summer
  • Longer Colder Winters
  • Growing Season now 170 Days
  • Pasture Productivity declined by Half
  • Higher Evaporation Rates

22
Dust Storms
  • More than 50 days of storms a year
  • 20-25 meters per second

23
Dust
  • Aral Sea is located along a powerful air stream
    running from west to east.
  • It contributes to aerosol
  • transference into upper
  • layers and fast spread in the
  • atmosphere of the Earth.

Dust Storm From Aral Region
24
Effects of Dust Storms
  • Reduces visibility to less than a quarter mile.
  • Respiratory ailments, Asthma
  • Erosion, Desertification, Crop Damage
  • The erosion loosens up contaminated toxic soils.

25
Dust
  • Traces of pesticides from the Aral region were
    found in the blood of penguins in the Antarctic
  • Aral dust has been found on Greenland's glaciers
  • Norway's forests
  • Belarus' fields
  • All situated thousands of kilometers away from
    Central Asia.

26
Anthrax
  • Vozrozhdeniya Island - New York Times Article
  • Renaissance Island
  • Anthrax Storage Facility
  • During Gorbachevs glasnost and perestroika
    campaign

27
Vozrozhdeniya Island
  • The island was once 77 square miles
  • In 1999 770 Square miles
  • Fear of Terrorism
  • Yeltsin vowed in 1992 to clean up
  • Uzbekistan and Kazakhstan have both independently
    asked for US help.

28
Radioactive Waste
  • MAYLUU-SUU, Kyrgyzstan
  • Outside the rusting, closed Izolit
    uranium-processing plant, 23 radioactive waste
    sites exist in the landslide-prone hills
  • Could spill poison into the river below and on to
    the most populous region of Central Asia.
  • About 70 million cubic feet of tailings left from
    refining uranium ore during the Soviet era are
    buried in this mountain valley along the
    Mayluu-Suu River.
  • Fergana Valley, the region's agricultural
    heartland with 12 million inhabitants.

29
Radioactive Waste
  • In Kazakhstan, huge mining and metallurgy
    complexes were built
  • They have never been modernized
  • Intense local air pollution.
  • In the west of Kyrgyzstan, radioactive waste from
    uranium plants is stocked without protection and
    risks polluting the rivers in neighboring
    Uzbekistan.
  • These Eventually may reach the Aral Sea.

32
Neutralization of the Problem
  • 1980s cultivation of new large irrigated areas
    banned
  • Large scale water resource projects introduced
  • 1993 Crosspiece Divided Aral Sea and water
    from the Syrdarya was diverted back into one
    part. Vegetation started to recover and salinity
    decreased.
  • It was destroyed in 1999

A footnote about the Aral Sea Disaster The
locals around the Aral sea joke that if everyone
who'd come to study this disaster had brought a
bucket of water, the sea would be full again by
now.
