The Aral Sea is a terminal lake amidst the deserts of Central Asia. Its size and water balance are fundamentally determined by river inflow and evaporation from its surface. Until the 1960s, the Aral was the world’s fourth largest lake in surface area. Over the A. Introduction 1 The two main sources of water in the Aral Sea basin of Central Asia, the Amu Darya and the Syr Darya, have been so diverted for irrigation in the last half century that the Aral Sea, once the world’s fourth–largest freshwater lake, has shrunk to less than a quarter of its volume. The depletion of the sea and these two → international watercourses has been called

This scientific article uses primary and secondary data to explore the history and current status of fishery culture in the Aral Sea region, the

The primary cause of the Aral Sea’s decline is human activities, most importantly the careless handling of the irrigation project that drained it. Kazakhstan assumed leadership of the International Fund for Saving the Aral Sea (IFAS) on January 1, 2024, underlining its commitment to One of the worst natural, economic, and social catastrophes caused by human activity is the Aral Sea crisis in Central Asia. The Aral Sea’s desiccation, which has an impact on the region’s overall sustainable development, human welfare, security, and survival, is what led to the problem. This study assesses the effects of economic expansion, population ageing, life

We present the first comprehensive taxonomic and environmental study of dinoflagellate cysts in 185 surface sediment samples from the Black Sea Corridor (BSC) which is a series of marine basins extending from the Aegean to the Aral Seas (including Marmara, Black, Azov and Caspian Seas). For decades, these low-salinity, semi-enclosed or endorheic basins None is them is from Karakalpakstan – the region where Aral Sea is located, so they have not directly witnessed the consequences of the crisis. Their interviews contribute to understanding of the level of awareness among the youth and their exploration of the problem, as well as their perception of potential solutions. The Caspian Sea lies in Eastern Europe, at the border between Europe and Central Asia. As the largest inland body of water on Earth, it has been vital to the economy of the surrounding regions. The Caspian sea was formed 30 million years ago, around the same time as the Black Sea and the Aral sea. However, it faces the adverse effects of climatic changes and

The Amudarya in the Southern Region and also Syrdarya in the Northern Region are both significant river containers in the Aral Sea. The Aral Sea obtains its water from these 2 rivers, which mostly depends upon dissolved snow, hence optimizing its amount in summertime. The Aralkum is a new desert created by the desiccation of the Aral Sea and is an efficient source of dust aerosol which perturbs the regional Central Asian radiation balance. COSMO–MUSCAT model

The Aral Sea International Program selected for the UN IDSSD supports the Green Aral Sea Initiative by fostering regional collaboration in green technologies to advance sustainable development across the region. It focuses on four core areas: researching ecosystem evolution and sustainable development in the Aral Sea region; piloting green and innovative Abstract. The restoration of the North Aral Sea was an unprecedented effort to save a large water basin by construction of a dam that separates it from the rest of the desiccating Aral Sea area. As a result, the lake volume has stabilized at 27.5 km3, the area has increased from 2800 km2 (2006) to 3400 km2 (2020), and the salinity has dropped from 18 to 10 g kg−1.

Once the world’s fourth-largest lake, the Aral Sea disappeared over three decades as the Soviets diverted its source rivers to serve Moscow’s regional irrigation schemes. Environmental Degradation in the Aral Sea Region The Aral Sea, located in Central Asia, is a prime example of severe environmental degradation that has led to the inability to support both wildlife and human communities. Once the fourth largest lake in the world, the Aral Sea has now shrunk to less than 10% of its original size. Causes of the

The Aral Sea, once one of the world’s largest lakes, is now a toxic desert. Explore how its disappearance reshaped the region. The World Bank’s Kokaral dam project has raised water levels and replenished fish in the North Aral Sea, reviving Kazakhstan fishing towns. Recent satellite imagery shows that the Aral Sea continues to disappear.

The Aral Sea region is one of the poorest in the oil producing states. Almost 90% of this lake has gone now because the rivers that fed the lake were used for irrigation by Soviet Union. – from technical advice to capacity building in the fields of climate change, agriculture, economic growth, governance, health and education, among others. In the Southeast Asian region alone, GIZ’s climate change, agriculture and forestry portfolio consists of [40] national projects and [10] regional projects to the amount of EUR [ ] million/billion.

Since its initial filling, the Aral Sea has periodically been connected with the Caspian Sea via the Sarykamysh Depression and the Uzboi Channel to the southeast, and this has been important for colonisation of marine biota (Boomer et al. 1996, 2000). Due to catastrophic desiccation, today’s Aral Sea consists of a few separate residual basins, characterized by different ecological conditions (the Large Aral, Lake Tshchebas, the Small Aral). This study is the first report on dissolved methane concentrations in these basins. Overall, 48 water samples were obtained and analyzed for Presents in a systematic description the knowledge accumulated on the physical oceanography, marine chemistry and biology, and pollution of the Aral Sea Based on numerous observational data of the authors, on archival data of several Russian oceanographic institutions and on the broad scientific literature mainly published in Russian editions Includes supplementary

What is the primary reason for the shrinking of the Aral Sea? A. There is climatic change in Central Asia. B. Large-scale irrigation projects implemented by the Soviets in the 1950s have diverted water from the two rivers that feed the sea. C. Tectonic rifting in the region is causing the sea’s water to be removed beneath the ground surface. D.

We review the past, present and possible future of the Aral Sea system in context of the human caused regression crisis that resulted in the drying out of the larger part of this original brackish water sea. The results are put into the context of

The Aral Sea has split into several separate water bodies, of which the most notable are the so-called Small Sea in the north and the Large Sea in the south (Figure 1). The latter consists of now almost separate western and eastern basins, connected through the narrow channel. Abstract. The article examines the history of the Aral Sea and the environmental disaster of the twentieth century associated with the disappearance of the world’s fourth sea body of water. A comprehensive author’s research at the interdisciplinary level showed the role and place of the Aral Sea from the moment of its formation in the surrounding space, its influence on the socio

Government-Led Initiatives and Regional Cooperation Kazakhstan’s commitment to restoring the Aral Sea is backed by strategic water management policies and regional cooperation. Speaking at a meeting with residents of the Aral district, Minister of Water Resources and Irrigation Nurzhan Nurzhigitov emphasized the significance of these efforts. “These figures

Vanishing Waters: From sea to dust

The eastern part of the Tethys Ocean is sometimes referred to as Eastern Tethys. The western part of the Tethys Ocean is called Tethys Sea, Western Tethys

The Aral Sea is also four times larger than Lake Balkash in surface area. But if those are the ultimate distinctions between a lake and an in-land sea, why is the Dead Sea a sea? It is only 15 km wide, after all, with a surface area 25 times smaller than Lake Balkash. After 225 million years of existence (1), 85% of the world’s sturgeons are nearing extinction (2). The sturgeon is particularly vulnerable to anthropogenic activities because it is large, moves slowly, migrates between saltwater and freshwater, and reproduces late and infrequently (3). The ship sturgeon (Acipenser nudiventris) distribution used to include the

Microplastic transport during desertification in drylands: Abundance and characterization of soil microplastics in the Amu Darya-Aral Sea basin, Central Asia The agricultural policies that prioritized cotton cultivation over ecological balance have had devastating consequences. The shrinking of the Aral Sea has not only resulted in the loss of marine life and biodiversity but has also halted economic development turning the lake into the Aralkum Desert (Gourlay,2015). This is the newest human made desert which reminds us

Abstract— Based on the literature and studies carried out by the authors over more than 30 years, an analysis of the fauna of crustaceans of the Aral Sea is presented. The faunal composition, the changes that have taken place since the 1950s, and the relations to the salinity factor are considered. Crustaceans in the Aral Sea make up about one-quarter of the
