The Aral Sea by Shawni Hedberg-Sola

Volume 1, Issue 1 8 Jun 2011 The Aral (Turkish for island) Sea is located in Central Asia between Kazakhstan and Uzbekistan. Positioned between the Black Desert and Red Desert, the Aral Sea was once the fourth largest inland sea in the world fed by the Amu Darya and Syr Darya rivers. This flourishing body of water spanned over 25,000 square miles providing fish and wildlife a sustaining ecosystem. Surrounding villages thrived comfortably from the economy of fishery and beach holi- Fishing on the Aral. Fishing was big business and brought in over 50,000 tons of fish per year.

Ecological Deterioration
Between 1960 and 1970, water from the Amu Darya and Syr Darya was diverted from the Aral Sea to the Kara Kum Canal. This water was used to irrigate cotton and rice export crops.

Climatic Changes
In the last decade, climatic changes have increased in the Aral Sea region. As a result of these changes, winters are longer and colder reaching temperatures below freezing. Summers are shorter and drier reaching temperatures of 113 degrees Fahrenheit. Precipitation has decreased and evaporation has increased causing an air pressure reduction of 10%. Dust storms occur at least fifty days annually with gusts peaking at 20-25 mph.

Economic Decline
A majority think cotton irrigation was the cause of the evaporated Aral, but for those fisherman who thrived from fishery, it is a fact.

Village Health
Uzbekistan villagers health has declined since the Aral Sea began to deteriorate. Over usage of pesticides, like DDT and HCB, over the years, has affected generations of families. Tuberculosis, respiratory diseases, asthma, typhus, blood disease, and increased birth defects have resulted from pesticide exposure, high mineral water consumption, and other environmental and social factors.

Restoration Efforts
Central Asian states meet annually to discuss Aral Sea recovery. In 2000 they had a vision for recovery, but have yet to act on it. Claims it would take 75 years to replenish the Aral Sea if the Amu Darya was open to run into have been discussed, but the time is a very discouraging factor. Kazakhstan and the World Bank have made actual efforts to restore the northern sector of the Aral Sea. An 8-mile dam was erected and seemingly water levels began to rise to 42 meters which replenished the northern end by 50%. Furthermore, salinity levels decreased by two-thirds which made the waters survivable by indigenous fish. To date, seven fish species have been returned to these waters after being raised in fish hatcheries built along the north end. Although positive recovery effects have occurred on the northern end, no movement end restorations has occurred.

Authors Comments
The Aral Sea once provided Central Asia a steady economic flow from its flowing waters. Fishery, cotton and rice export, and resorts brought in a comfortable revenue to sustain the lives of those who lived in surrounding villages. Slowly the Aral Sea level lowered which destroyed its ecosystem, changed the regions climate, eliminated livelihood, and caused lifethreatening illness and disease because of air pollution. Nothing positive seemed to possible for this region for the longest time and as the years past the sea level continued to drop. Today, with the efforts of the World Bank and the Khazakhstan government, over $100 million dollars in restoration efforts have enabled the northern Aral Sea to refill to a noticeable level. Continued restoration efforts will continue on the north end as they have since 2001, but south Aral Sea recovery has only been a dream. The hope and dream of those communities which dwell on the south Aral Sea will not return to sea level anywhere near the level it was before 1960. Opening up the two main rivers to refill the south Aral Sea would be a great start. The effects poisonous pesticides have ridden communities generation after generation causing illness, diminishing health, and decreased lifespans. For the future of Central Asia habitants, in April 2011, the World Bank granted Uzbekistan a $93 million bank loan for health reform. A positive step to aid the most important part of this region— the people.

Lesson

...The Aral Sea is actually not a sea at all. It is an immense lake, a body of fresh water, although that particular description of its contents might now be more a figure of speech than practical fact. In the last 30 years, more than 60 percent of the lake has disappeared. The sequence of images above, acquired by Landsat satellites, shows the dramatic changes to the Aral Sea between 1973 and 2000. Beginning in the 1960s, farmers and state offices in Uzbekistan, Kazakhstan, and Central Asian states opened significant diversions from the rivers that supply water to the lake, thus siphoning off millions of gallons to irrigate cotton fields and rice paddies. As recently as 1965, the Aral Sea received about 50 cubic kilometers of fresh water per year—a number that fell to zero by the early 1980s. Consequently, concentrations of salts and minerals began to rise in the shrinking body of water. That change in chemistry has led to staggering alterations in the lake's ecology, causing precipitous drops in the Aral Sea’s fish population. The Aral Sea supported a thriving commercial fishing industry employing roughly 60,000 people in the early 1960s. By 1977, the fish harvest was reduced by 75 percent, and by the early 1980s the commercial fishing industry had been eliminated. The shrinking Aral Sea has also had a noticeable affect on the region's climate. The growing season there is now shorter, causing many farmers to switch from cotton to rice, which demands even more diverted water. ...

Turkemistant Swot Analysis

...Turkmenistan is one of the Turkic states in Central Asia bordered by Kazakhstan, Uzbekistan, Afghanistan, Iran, and the Caspian Sea. It gained its independence upon the dissolution of the Soviet Union in 1991. Upon researching the country and reading different articles, I will be conducting a SWOT analysis to evaluate the strengths, weaknesses, opportunities, and threats involved with the country. Strengths being characteristics of the country that give it an advantage over others, weaknesses being characteristics that place the country at a disadvantage to others, opportunities being elements that the country could use to its advantage, and threats being elements that could cause problems for the country. Turkmenistan’s country has many good aspects about it. The land and resources available contribute to a lot of the strengths that Turkmenistan has. The country has large areas for non-irrigated farming. Mountains and foothills within the region are rich in mineral resources. With the resources available, the people who live there are able to produce cotton silk, handmade carpets and rugs, and raise cattle, sheep, goats, and camels. The raising of this livestock contributes most to the agricultural economy. They use camels for transporting sheepherders, drawing water from the desert wells, and as a main source of meat, wool, and milk. This country is one of the most industrially developed regions of the republic. Oil extraction and refining, fisheries and fish processing...

Karakalpakstan

...Karakalpakstan Kayla Woodhouse Summer, 2015 Introduction The Aral Sea has been a source of jobs, stability, and nutrition for centuries. But since the time when Uzbekistan was under the control of the Russian government – the Union of Soviet Socialist Republics, also known as USSR and the Soviet Union – the region has experienced many difficulties. The Aral Sea was once the fourth largest lake in the world, but it has shrunk in tremendous proportions causing many effects such as pollution, temperature fluctuations, and disease. In this paper, six of the nine thematic concepts of geography are examined in Uzbekistan, and specifically in the region around the Aral Sea, Karakalpakstan. The topics covered are society, politics, environment, economy, culture, and history. History The history and story of Uzbekistan is an essential part of Central Asian development. Until the mid-1920s, the region of Uzbekistan and its neighboring countries was called Turkestan. After the campaigns of Alexander the Great during the 330-320s BC, Uzbekistan (then Turkestan) became a major trade center because of its location and the emergence of the Silk Road. In the 900s, Turkestan became deeply rooted in the Muslim religion. In the second half of the 19th century the Russian empire had conquered much of the region. Cotton became a major crop in both rural and urbanized areas. But many people were dissatisfied with the Russian rule and revolted. By 1916,rebellions – both large and small –...

...The changed course of the sea was a skewed route going to the Aral Sea and it left the areas that were linked with the Aral Sea and Caspian Sea with no water. Soon the areas were left, and they became deserts. The lands that became deserts were used by the empire rulers as boundary markers. The pastoral nomad groups wanted to turn the regions into territorial expansions. Pastoral nomads joined with other states and used their horse riding abilities. Many of these nomads were Turkic people whose mission was to control lands that were unpopulated in the across the Aral and Caspian seas. There was a problem however, as the environmental consequences started to get worse for the people living in the Aral and Caspian areas that pastoral nomad groups had to resettle and flee from their locations. The areas that they fled to be a lot friendlier and social. According to Khazeni though the effects of the environment played a huge factor in how these nomads made their decisions.

...cattle or grow crops to provide food for the worlds growing population. With the increase in agricultural also comes with it a series of environmental problems that end up hurting the earth as well as ourselves in the process. Although agriculture can help provide much needed food for the world population, the fact is that the earth cannot healthily sustain and produce this much food without some extreme environmental consequences. Agriculture both directly affects the local wildlife as well as damages ecosystems. About 70% of the earth’s freshwater withdrawals are in fact due to crop irrigation. Withdrawing this much freshwater can majorly impact the ecosystem as well as the local human population with no better example of this then Aral Sea area in Russia. Not only does agriculture effect common animals but also effects endangered and threatened species, approximately 53% of the species on the threatened list are directly and negatively affected by agriculture.

The Turan tiger was in the past found populating a multitude of areas like the southeast hill and lowland forests of the Caucasus, lowlands forests of Priship, and subsequently moved toward the eastern plains of the Trans-Caucasus, and the Zangezur Mountains. Within Middle Asia it populated the southwestern Turkmenia, Sumbar and Chandyr rivers; in the western and southwestern parts of Kapet- Dag, the northern foothills of Ashkabad, in the Afghanistan upper range at Herat and along the jungles in the lower river areas around Tedzhen, Murgap, Kushka, and Kashan rivers.

Water Drainage Techniques

...Water drainage techniques, materials, processes and maintenance (Name of Student) (Name of Institution) Water drainage techniques, materials, processes and maintenance Under ordinary conditions rain water seeps into the ground and forms underground water. Most of the water that falls as rain soaks into the ground or gets carried away by rivers. But in urban areas, the built environment alters the natural drainage of water, with hard surfaces increasing both the rate and amount of rainwater that turns into run-off. And it has to go somewhere. Traditional piped ‘drains’ have a limited capacity to cope with the high levels of surface water generated by extreme rainfall events. And, when the capacity of one or more parts of the drainage system is exceeded, the worst happens. For example, in the floods of June 2007, extreme rainfall in the Midlands and the north of England led to large-scale urban flooding, with over 55,000 properties affected: two thirds of these were from surface water run-off overloading drainage systems. In addition to flood risk, large amounts of surface water run-off can cause water quality problems. As water runs over hard urban surfaces, it picks up pollutants that are washed into water courses. For example, run-off from roads contains heavy metals and hydrocarbons which can seriously impact on water quality. A well planned drainage infrastructure helps to manage water run-off by preventing domestic...
