of the near-endemic amphipod ''Dikerogammarus aralensis'', which now survives only in the Syr Darya basin. The copepod ''
Calanipeda aquaedulcis'' was introduced to the Aral to replace the zooplankton species reduced by the herring population, and the
North American mud crab ''
Rhithropanopeus harrisii'' was inadvertently introduced during this attempt as well.
Later, as the lake's salinity increased, many of the freshwater-adapted species disappeared, only leaving behind the marine and saline species. However, the zooplankton population in the North Aral Sea has recovered as salinity has decreased from the 1990s onwards, with extirpated crustacean and rotifer species returning naturally via the Syr Darya River, at the expense of the saltwater species. The cladoceran ''
Moina mongolica'', extirpated by the introduced fish species, has also returned. The zebra mussel (''Dreissena polymorpha aralensis'') has been reintroduced. In contrast, in the South Aral Sea only a few
nematodes, rotifers, and
parthenogenic brine shrimp (''Artemia parthenogenetica'') exist. The future prospects for aquatic invertebrates in all remaining Aral Sea fragments depend on their future changes in salinity.
History
Climate shifts have driven multiple phases of sea-level rise and fall. Inflow rates from the Amu Darya and Syr Darya are affected by glacial melt rates at the rivers' headwaters as well as precipitation within the river basins and cold, dry climates restrict both processes.
[Cretaux et al. 2013, pp. 100, 105-106] Geologically driven shifts in the course of the Amu Darya between the Aral Sea and the Sarykamysh basins and anthropogenic water withdrawal from Amu Darya and Syr Darya have caused fluctuations in the Aral Sea's water level.
Artificial irrigation systems began in ancient times and continue to the present.

[Ryszard Kapuscinski, ''Imperium'', 2019, pp.255-260.] This temporarily succeeded, and in 1988, Uzbekistan was the world's largest exporter of cotton. Cotton production is still
Uzbekistan's main cash crop, accounting for 17% of its exports in 2006.
Large scale construction of irrigation canals began in the 1930s and was greatly increased in the 1960s.
[Simon N. Gosling, ''Sustainability - The Geography Perspective'', University of Nottingham, 2012] Many canals were poorly built, allowing leakage and evaporation. Between 30 and 75% of the water from the
Qaraqum Canal, the largest in Central Asia, went to waste.
It was estimated in 2012 that only 12% of Uzbekistan's irrigation canal length was waterproofed.
Only 28% of interfarm irrigation channels, and 21% of onfarm channels have
anti-infiltration linings, which retain on average 15% more water than unlined channels. Only 77% of farm intakes have
flow gauges.
By 1960, between of water each year was going to the land instead of the Aral Sea and the sea began to shrink. From 1961 to 1970, the Aral's level fell an average of per year. In the 1970s the rate nearly tripled to per annum, and in the 1980s to per annum. The amount of water taken for irrigation from the rivers doubled between 1960 and 2000. In the first half of the 20th century prior to the irrigation, the sea's water level above sea level held steady at 53 m. By 2010 the large Aral was 27 m and the small Aral 43 m above sea level.
The disappearance of the lake was no surprise to the Soviets, they expected it to happen long before. As early as 1964, Aleksandr Asarin at the

and the
Politburo. Nobody on a lower level would dare to say a word contradicting those plans, even if it was the fate of the Aral Sea."
The reaction to the predictions varied. Some Soviet experts apparently considered the Aral to be "nature's error", and a Soviet engineer said in 1968, "it is obvious to everyone that the evaporation of the Aral Sea is inevitable." On the other hand, starting in the 1960s, a
large-scale project was proposed to redirect part of the flow of the rivers of the
Ob basin to Central Asia over a gigantic canal system. Refilling of the Aral Sea was considered one of the project's main goals. However, due to its staggering costs and the negative public opinion in
Russia proper, the federal authorities had abandoned the project by 1986.
From 1960 to 1998, the sea's surface area shrank by 60%, and its volume by 80%. In 1960, the Aral Sea had been the world's
fourth-largest lake with an area of and a volume of . By 1998, it had dropped to and eighth largest. Its salinity increased, by 1990 it was at 376 g/L.
(By comparison, seawater is typically 35 g/L, and the
Dead Sea between 300 and 350 g/L.)
In 1987, the lake split into two separate bodies of water, the

In 2003, the South Aral further divided into eastern and western basins. The waters in the deepest parts of the sea were saltier and not mixing with the top waters, so only the top of the sea was heated in the summer and it evaporated faster than had been predicted. A plan was announced to recover the North Aral Sea by building

s feeding into it have been nearly destroyed, largely because of the drastically higher salinity than seawater.
The receding sea has left huge plains covered with salt and toxic chemicals from
weapons testing, industrial projects, and pesticides and fertilizer runoff. Due to the shrinking water source and worsening water and soil quality, pesticides were increasingly used from the 1960s to raise cotton yield, which further polluted the water with toxins (e.g.
DDT

and heavy metal contamination.
Due to the minimal amount of water left in the Aral sea, concentrations of these pollutants have risen drastically in remaining water and dry beds. This results in wind-borne toxic dust that spreads quite widely. People living in the lower parts of the river basins and former shore zones ingest pollutants through local drinking water and inhalation of contaminated dust. Furthermore, due to absorption by plants and livestock, toxins have entered the food chain; many of these bioaccumulate and are not easily broken down/excreted by the liver and kidneys.

Inland seas and lakes generally moderate a region's climate by moistening, regulating thermal energy and peri-winter

Loss of water in the Aral Sea has changed surface temperatures and wind patterns. This has led to a broader annual temperature range (about a 4˚ to 12˚C broadening) and more dust in storms locally and regionally.
Biology
The Aral Sea fishing industry, which at its peak employed some 40,000 and reportedly produced one-sixth of the Soviet Union's entire fish catch, has been devastated. In the 1980s commercial harvests were becoming unsustainable, and by 1987 commercial harvest became nonexistent. Due to the declining sea levels, salinity levels became too high for the 20 native fish species to survive. The only fish that could survive the high-salinity levels was flounder. Also, as water has receded, former fishing towns along the original shores have become

s.
Aral, originally the main fishing port, is now about 15 kilometres from the sea and has seen its population decline dramatically since the beginning of the crisis. The town of
Moynaq in Uzbekistan had a thriving harbour and fishing industry that employed about 30,000 people; now it lies 30–90 kilometres from the shore. Fishing boats lie scattered on the dry dusty land that was once covered by water; many have been there for 20 years.
The South Aral Sea remains too saline to host any species other than

organisms. The South Aral has been incapable of supporting fish since the late 1990s, when the flounder were killed by rising salinity levels.

Vulnerable populations
Women and children are the most vulnerable populations in this environmental health crisis due to the highly polluted and salinated water used for drinking and the dried seabed.
Toxic chemicals associated with pesticide use have been found in blood and breast milk of mothers; specifically organochlorides, polychlorinated biphenyl compounds (PCBs), DDT compounds, and TCDD.
These toxins can be, and often are, passed on to the children of these mothers resulting in low birthweight children and children with abnormalities. The rate of infants being born with abnormalities is five times higher in this region than in European countries.
The Aral Sea region has 26% of its children born at low birthweight, which is two standard deviations away from a national study population gathered by the WHO.
Exposures to toxic chemicals from the dry seabed and polluted water have caused other health issues in women and children. Renal tubular dysfunction has become a large health concern in children in the Aral Sea region as it is showing extremely high prevalence rates. Renal tubular dysfunction can also be related to growth and developmental stunting. This, in conjunction with the already high rate of low birth weight children and children born with abnormalities, poses severe negative health effects and outcomes on children. These issues are compounded by the lack of research of maternal and child health effects caused by the demise of the Aral Sea. For example, only 26 English-language peer-reviewed articles and four reports on children's health were produced between 1994 and 2008.
In addition, there is a lack of health infrastructure and resources in the Aral Sea region to combat the health issues that have arisen.
There is a lack of medication and equipment in many medical facilities, so health professionals do not have access to the necessary supplies to do their jobs in the Kazakhstan and Uzbekistan regions.
There is also meager development of a health information system that would allow for extensive research or surveillance of emerging health issues due to Aral sea issues.
An absence of a primary care approach in the health systems of this region also hinders services and access that could prevent and treat issues stemming from the Aral Sea crisis, especially in women and children.
The impoverished are also particularly vulnerable to the environmental and health related effects of changes to the Aral Sea. These populations were most likely to reside downstream from the Basin and in former coastal communities.
They were also among the first to be detrimentally affected, representing at least 4.4 million people in the region.
Considered to have the worst health in this region, their plight was not helped when their fishery livelihoods vanished with the decreasing levels of water and loss of many aquatic species.
Thus, those in poverty are entrenched in a vicious cycle.

. In 1994, they adopted the Aral Sea Basin Programme.
The Programme's four objectives are:
*To stabilize the environment of the Aral Sea Basin
*To rehabilitate the disaster area around the sea
*To improve the management of the international waters of the Aral Sea Basin
*To build the capacity of institutions at the regional and national level to advance the programme's aims
ASBP: Phase One
The first phase of the plan effectively began with the first involvement from the World Bank in 1992, and was in operation until 1997. It was ineffectual for a number of reasons, but mainly because it was focused on improving directly the land around the Aral Sea, whilst not intervening in the water usage upstream. There was considerable concern amongst the Central Asian governments, which realised the importance of the Aral Sea in the ecosystem and the economy of Central Asia, and they were prepared to cooperate, but they found it difficult to implement the procedures of the plan.
This is due in part to a lack of co-operation among the affected people. The water flowing into the Aral Sea has long been considered an important commodity, and trade agreements have been made to supply the downstream communities with water in the spring and summer months for irrigation. In return, they supply the upstream countries with fuel during the winter, instead of storing water during the warm months for hydroelectric purposes in winter. However, very few legal obligations are binding these contracts, particularly on an international stage.
ASBP: Phase Two
Phase Two of the Aral Sea Basin programme followed in 1998 and ran for five years. The main shortcomings of phase two were due to its lack of integration with the local communities involved. The scheme was drawn up by the World Bank, government representatives, and various technical experts, without consulting those who would be affected. An example of this was the public awareness initiatives, which were seen as propagandist attempts by people with little care or understanding of their situation. These failures have led to the introduction of a new plan, funded by a number of institutions, including the five countries involved and the World Bank.
ASBP: Phase Three
In 1997, a new plan was conceived which would continue with the previous restoration efforts 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. The largest project in this phase is the North Aral Sea Project, a direct effort to recover the northern region of the Aral Sea. The North Aral Sea Project's main initiative is the construction of a dam across the Berg Strait, a deep channel which connects the North Aral Sea to the South Aral Sea. The Kok-Aral Dam is long and has capacity for over 29 cubic kilometres of water to be stored in the North Aral Sea, whilst allowing excess to overflow into the South Aral Sea.
Aral Sea Basin Programme – 2
On 6 October 2002, the Heads of States met again to revise the ASBP program. ASBP-2 was in place from 2003 to 2010. The main purpose of the ASBP-2 was to set up projects that covered a vast amount of environmental, socioeconomic and water management issues. The ASBP-2 was financed by organization such as the UNDP, World Bank, USAID, Asian Development Bank, and the governments of Switzerland, Japan, Finland, Norway and others. Over 2 billion US Dollars was provided by the IFAS country members to the program.
Aral Sea Basin Programme – 3
On 28 April 2009, the Head of States came together with the Interstate commission for Water Coordination, Interstate Commission for Sustainable Development and National Experts and donors to develop the ASBP-3. This Program was in effect from 2011- 2015. The main purpose of the ASBP-3 was to improve the environmental and socio-economic situation of the Aral Sea Basin. The four program prioritizes were:
*Direction one: Integrated Use of Water Resources
*Direction two: Environmental protection
*Direction three: Socio-economic Development
*Direction four: Improving the institutional and legal instruments
ASBP-3: Direction One
Direction One's main purpose is to propose program that focus on addressing transboundary water resources management, establishment of monitoring systems and addressing safety concerns in water facilities. Examples of programs that have been proposed include:
*"Developing proposals to optimize the management and use of water resources in Central Asia, taking into account environmental factors, effects of climate change to meet the national interests of the Aral Sea basin."
*"Improving the quality of hydrometeorological services for weather-dependent sectors of the economy of Central Asia."
*"Creating a database and computer models for the management of transboundary water resources."
*"Assisting the countries in reducing the risk of natural disasters, including through the strengthening of regional cooperation, improve disaster preparedness and response."
ASBP-3: Direction Two
Directions two's main focus is on addressing the issues related to environmental protection and improvement of the environment. Areas of interest include:
*"The environment in the deltas of the Syr Darya and Amu Darya improved."
*"Mountain environments improved."
*"The environment and productivity of pastures improved."
*"A regional information system on the environment established."
ASBP-3: Direction Three
Direction three looks to address socio-economic issues by focusing on education and public health, improving unemployment rates, improving water systems, increasing sustainable development and improving living conditions. The expected outputs are:
*"An improved access to safe drinking water."
*"For the rural population: establishment and/or development of private small enterprises, creation of new jobs, and increased labor efficiency."
*"An improvement in the quality of medical services"
*"An improvement in the effectiveness and quality of education in schools and pre-school facilities in rural areas."
ASBP-3: Direction Four
Direction Four aims to address issues related to institutional development and the development of policies and strategies that relate to sustainable development and public awareness. Expected outputs include:
*"Conditions for a transparent and mutually beneficial regional dialogue and cooperation, including setting up a sectorial dialogue between governments established."
*"A Prototype of the single information and analysis system for the water sector established."
*"A Communication Strategy for stakeholders and the public established."
*"Training systems for the water sector and the hydrometeorological services in Central Asia improved."
North Aral Sea restoration work
Work is being done to restore in part the North Aral Sea. Irrigation works on the Syr Darya have been repaired and improved to increase its water flow, and in October 2003, the Kazakh government announced a plan to build
Dike Kokaral
Dike Kokaral is a 12 km long dam across a narrow stretch of the former Aral Sea, splitting off the North Aral Sea (also called "The Small Sea") from the area that once contained the much larger South Aral Sea ("The Large Sea"). The dike is c ...
, a concrete dam separating the two halves of the Aral Sea. Work on this dam was completed in August 2005; since then, the water level of the North Aral has risen, and its salinity has decreased. , some recovery of sea level has been recorded, sooner than expected.
"The dam has caused the small Aral's sea level to rise swiftly to 38 m (125 ft), from a low of less than 30 m (98 ft), with 42 m (138 ft) considered the level of viability."
Economically significant stocks of fish have returned, and observers who had written off the North Aral Sea as an environmental disaster were surprised by unexpected reports that, in 2006, its returning waters were already partly reviving the fishing industry and producing catches for export as far as Ukraine. The improvements to the fishing industry were largely due to the drop in the average salinity of the sea from 30 grams to 8 grams per liter; this drop in salinity prompted the return of almost 24 freshwater species.
The restoration also reportedly gave rise to long-absent rain clouds and possible microclimate changes, bringing tentative hope to an agricultural sector swallowed by a regional

Aralsk, is now a mere away. The Kazakh Foreign Ministry stated that "The North Aral Sea's surface increased from in 2003 to in 2008. The sea's depth increased from 30 meters (98 ft) in 2003 to 42 meters (138 ft) in 2008."
Now, a second dam is to be built based on a World Bank loan to Kazakhstan, with the start of construction initially slated for 2009 and postponed to 2011, to further expand the shrunken Northern Aral, eventually reducing the distance to Aralsk to only . Then, it was planned to build a canal spanning the last 6 km, to reconnect the withered former port of Aralsk to the sea.
On 15 June 2021 the Central Communications Service of Kazakhstan announced that they plan to plant
saxaul trees on one million hectares of the drained bottom of the Aral Sea as part of efforts to stop dust storms on the region. Other efforts include expanding the sea's water mirror.
Future of South Aral Sea
The South Aral Sea, half of which lies in Uzbekistan, was abandoned to its fate. Most of Uzbekistan's part of the Aral Sea is completely shriveled up. Only excess water from the North Aral Sea is periodically allowed to flow into the largely dried-up South Aral Sea through a
sluice in the dyke. Discussions had been held on recreating a channel between the somewhat improved North and the desiccated South, along with uncertain wetland restoration plans throughout the region, but political will is lacking.

river to irrigate their cotton, and is moving toward oil exploration in the drying South Aral seabed.[
Attempts to mitigate the effects of desertification include planting vegetation in the newly exposed seabed; however, intermittent flooding of the eastern basin is likely to prove problematic for any development. Redirecting what little flow there is from the Amu Darya to the western basin may salvage fisheries there while relieving the flooding of the eastern basin.

in the hopes of solving environmental, as well as socioeconomic problems in the Aral Sea region. The River Basin Organizations (the BVOs) of the Syr Darya and Amu Darya rivers were institutions called upon by the ICWC to help manage water resources. According to the ICWC, the main objectives of the body are:
* River basin management
* Water allocation without conflict
* Organization of water conservation on transboundary water courses
* Interaction with hydrometeorological services of the countries on flow forecast and account
* Introduction of automation into head structures
* Regular work on ICWC and its bodies' activity advancement
* Interstate agreements preparation
* International relations
* Scientific research
* Training
The International Fund for Saving the Aral Sea (IFAS) was developed on 23 March 1993, by the ICWC to raise funds for the projects under Aral Sea Basin programmes. The IFAS was meant to finance programmes to save the sea and improve on environmental issues associated with the basin's drying. This programme has had some success with joint summits of the countries involved and finding funding from the World Bank to implement projects; however, it faces many challenges, such as enforcement and slowing progress.
