Finally, Microsoft Excel software was used to graph water surface area over time and the best fit line of this data was used to infer average Aral Sea loss in water surface area per year from to Vast areas of solonchaks and strongly saline lands, being sources of salt and dust transfer due to wind erosion, have occurred here.
Driving around the sea bed is a strange experience, she says. Motivated by geo-political issues, the United States government has pursued a policy through economic, political, and environmental assistance programs to assist Central Asian states.
Time Series showing change in water surface area from Landsat imagery left column and derived cluster analysis in Idrisi right column. Salt and pesticide chemicals have seeped into groundwater and caused health disasters and further complications for agriculture.
It was right here where we stand now. Abandoned fishing vessel stranded on the dry basin of the Aral Sea Wikimedia Commons, Afghanistan, Iran, Kyrgyzstan, Tajikstan, and Turkmenistan. American business interests require a stable political and economic climate particularly in the energy zone.
Fishing ports suddenly found themselves in a desert. In fact, most of the countries in the region actually intend to increase irrigation in order to support growing populations.
Introduction Degradation of the Aral Sea and South Prearalie Introduction The tragedy of Aral Sea disappearance is one of the most convincing and vivid cases against unbalanced activities undertaken by the human society neglecting sustainable development, which are so numerous in the creative and simultaneously destructive latter half of the 20th century.
There is no river to replenish the water evaporating in the heat of the Central Asian summer, and little rainfall. The receding sea has left huge plains covered with salt and toxic chemicals resulting from weapons testingindustrial projects, and pesticides and fertilizer runoff.
The diminishing sea Physiographic changes In the surface of the Aral Sea lay feet 53 metres above sea level and covered an area of some 26, square miles 68, square km. Christopher Staecker The health costs to people living in the area began to emerge soon after water levels had dropped enough to uncover portions of the seabed.
Although measures have been taken on a limited scale to address the environmental and health problems in the basin, no conclusive or all-encompassing program has yet to make satisfactory progress.
During its history the Aral Sea has shrunk out several times as evidenced by the numerous remains of flora and fauna found in the dried bed of the Aral Sea. The main aims of this phase are to improve the irrigation systems currently in place, whilst targeting water management at a local level.
Geology The Aral Sea depression was formed toward the end of the Neogene Period which lasted from about 23 to 2. In the deepest parts of the sea, the bottom waters were saltier than the top, and not mixing. The groundwater originates in the Pamirs and Tian Shan Mountains and finds its way through geological layers to a fracture zone  at the bottom of the Aral.
The scheme was drawn up by the World Bank, government representatives, and various technical experts, without consulting those who would be affected. Nobody on a lower level would dare to say a word contradicting those plans, even if it was the fate of the Aral Sea.
People talk about the days when Aralsk was full of people selling fish, the cheapest fish given away for almost nothing. Araloriginally the main fishing port, is now several miles from the sea and has seen its population decline dramatically since the beginning of the crisis.
Since then the Syr Darya, in the north, and the Amu Darya, in the south, each of which carried water across the Central Asian steppes from as far away as the mountain ranges of Tien-Shan and the Pamirs, have flowed not into the Aral but instead into a canal system that irrigates vast fields of cotton.
Although this project spent tens of millions of dollars in ten years, the first goal is no longer thought feasible, the second and third are just getting underway. Then five months ago, in Octoberthe eastern sea disappeared, leaving just the Small Aral and the western basin.It’s a dead sea, without fish, and it’s still shrinking.
There is no river to replenish the water evaporating in the heat of the Central Asian summer, and little rainfall.
By contrast, in Kazakhstan at the northern end of the no-longer-existing Aral Sea, the Small Aral has been making a comeback, for two reasons.
With the breakup of the Soviet Union, the responsibility for the Aral Sea was transferred to the independent republics (Kazakhstan, Uzbekistan, Turkmenistan, Tajikistan, and Kyrgyzstan) that together with Afghanistan share the Aral Sea watershed.
Aral Sea A satellite image of the northern portion of the Aral Sea in ; the lighter-coloured areas represent sections of the seabed that have been exposed since U.S. Geological Survey Beginning aboutthe Aral Sea’s water level was systematically and drastically reduced, because of the diversion of water from the Amu Darya and Syr Darya rivers for purposes of agricultural irrigation.
History of the Aral Sea: from Antiquity to Present The results of the researches carried out under the Project “Integrated Water Resources Management for Wetlands Restoration in the Aral Sea Basin” being implemented under the NATO Program “Science for Piece” were published in the monograph “South Priaralie: New Prospects” printed by the Scientific-Information Center of ICWC in History and Analysis of Water Loss in the Aral Sea By Justin Abel, Daniel O'Crowley, and Logan Sleezer ES Remote Sensing Introduction: Once the world’s fourth largest lake, the Aral Sea supported thriving fishing and fur harvesting industries.
economic development of Aral sea. At the same time a decade ago the International Fund for saving the Aral was established. To this date the authors decided to dedicate this small book, chronologically enlighten the history of studying and development of Aral basin.Download
