Environmental Issues In Uzbekistan
Uzbekistan is a country in Central Asia, located north of Turkmenistan and Afghanistan. With an area of approximately 448,900 square kilometers, Uzbekistan stretches from west to east and from north to south. It borders Turkmenistan to the southwest, Kazakhstan to the north and Tajikistan and Kyrgyzstan to the south and east. Uzbekistan also has four small exclaves in Turkmenistan. Uzbekistan is the only Central Asian state to border all of the other four. Uzbekistan also shares a short border with Afghanistan to the south. As the Caspian Sea is an inland sea with no direct link to the oceans, Uzbekistan is one of only two "doubly landlocked" countries—countries completely surrounded by other landlocked countries. The other is Liechtenstein. Topography and drainage The physical environment of Uzbekistan is diverse, ranging from the flat, desert topography that comprises almost 80% of the country's territory to mountain peaks in the east reaching about above sea level.

Syr Darya
The Syr Darya ( ),; ; ; ; ; /. historically known as the Jaxartes ( , ), is a river in Central Asia. The name, which is Persian language, Persian, literally means ''Syr Sea'' or ''Syr River''. It originates in the Tian Shan, Tian Shan Mountains in Kyrgyzstan and eastern Uzbekistan and flows for west and north-west through Uzbekistan, Sughd province of Tajikistan, and southern Kazakhstan to the North Aral Sea, northern remnants of the Aral Sea. It is the northern and eastern of the two main rivers in the endorheic basin of the Aral Sea, the other being the Amu Darya. In the Soviet Union, Soviet era, extensive irrigation projects were constructed around both rivers, diverting their water into farmland and causing, during the post-Soviet era, the virtual disappearance of the Aral Sea, once the world's fourth-largest lake. The point at which the river flows from Tajikistan into Uzbekistan is, at above sea level, the lowest elevation in Tajikistan. Name The second part of the nam ...

Arid
Aridity is the condition of geographical regions which make up approximately 43% of total global available land area, characterized by low annual precipitation, increased temperatures, and limited water availability.Perez-Aguilar, L. Y., Plata-Rocha, W., Monjardin-Armenta, S. A., Franco-Ochoa, C., & Zambrano-Medina, Y. G. (2021). The Identification and Classification of Arid Zones through Multicriteria Evaluation and Geographic Information Systems—Case Study: Arid Regions of Northwest Mexico. ''ISPRS International Journal of Geo-Information'', ''10''(11), 720. https://doi.org/10.3390/ijgi10110720 These areas tend to fall upon degraded soils, and their health and functioning are key necessities of regulating ecosystems’ atmospheric components. Change over time The distribution of aridity at any time is largely the result of the general circulation of the atmosphere. The latter does change significantly over time through climate change. For example, temperature increase by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Steppe
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSh'' and ''BSk'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): * multi ...

Cold Desert
Cold Desert Biosphere Reserve is a biosphere reserve located in the Western Himalayas, within Himachal Pradesh in North India. It was established as a biosphere reserve in August 2009. Biosphere reserves are the areas of terrestrial and coastal ecosystems which promote the conservation of biodiversity with its sustainable use. There are over 738 biosphere reserves around the world in over 134 countries . The ministry of environment and forest provides financial assistance to the respective state governments for conservation of landscape, biological diversity and the cultural heritage. This region has the status of a Cold Desert biome, for two reasons, one is the leeward part of the Himalayas which is spared from monsoon winds and the other is its position at high altitude, on average 3000–5000 metres. Geography Cold Desert has an area of . The biosphere reserve encompasses the Chandra Taal, Kibber Wildlife Sanctuary, Pin Valley National Park and Sarchu. Location The col ...

Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...

Humid Continental Climate
A humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900, typified by four distinct seasons and large seasonal temperature differences, with warm to hot (and often humid) summers, and cold (sometimes severely cold in the northern areas) and snowy winters. Precipitation is usually distributed throughout the year, but often these regions do have dry seasons. The definition of this climate in terms of temperature is as follows: the mean temperature of the coldest month must be below or depending on the isotherm, and there must be at least four months whose mean temperatures are at or above . In addition, the location in question must not be semi-arid or arid. The cooler ''Dfb'', ''Dwb'', and ''Dsb'' subtypes are also known as hemiboreal climates. Although amount of snowfall is not a factor used in defining the humid continental climate, snow during the winter in this type of climate is almost a guarantee, either intermitte ...

Mediterranean Climate
A Mediterranean climate ( ), also called a dry summer climate, described by Köppen and Trewartha as ''Cs'', is a temperate climate type that occurs in the lower mid-latitudes (normally 30 to 44 north and south latitude). Such climates typically have dry summers and wet winters, with summer conditions being hot and winter conditions typically being mild. These weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to the ocean, altitude and geographical location. The dry summer climate is found throughout the warmer middle latitudes, affecting almost exclusively the western portions of continents in relative proximity to the coast. The climate type's name is in reference to the coastal regions of the Mediterranean Sea, which mostly share this type of climate, but it can also be found in the Atlantic portions of Iberia and Northwest Africa, the Pacific portions of the United States ...

1966 Tashkent Earthquake
The 1966 Tashkent earthquake (; ; ) occurred on 26 April in the Uzbek SSR. It had a moment magnitude of 5.2 with an epicenter in central Tashkent at a depth of . The earthquake caused massive destruction to Tashkent, destroying most of the buildings in the city, killing between 15 and 200 people and leaving between 200,000 and 300,000 homeless. Following the disaster, most of the historic parts of Tashkent had been destroyed and the city was rebuilt, based on Soviet architectural styles. Soviet authorities created an institute of seismology in order to forecast future earthquakes. Background Tashkent and its immediate vicinity are in a seismically active zone, and 74 earthquakes of a magnitude between 3 and 6 had been recorded from 1914 to 1966. The city had been damaged by earthquakes in 1866 and 1886. Concerns about possible earthquake damage to the city were raised in the 1940s and 1950s, especially after Ashgabat was devastated in an earthquake in 1948. Before the Tashkent ...

Tashkent
Tashkent (), also known as Toshkent, is the Capital city, capital and List of cities in Uzbekistan, largest city of Uzbekistan. It is the most populous city in Central Asia, with a population of more than 3 million people as of April 1, 2024. It is located in northeastern Uzbekistan, near the border with Kazakhstan. Before the influence of Islam in the mid-8th century AD, Sogdian people, Sogdian and Turkic people, Turkic culture was predominant. After Genghis Khan destroyed the city in 1219, it was rebuilt and profited from its location on the Silk Road. From the 18th to the 19th centuries, the city became an Tashkent (1784), independent city-state, before being re-conquered by the Khanate of Kokand. In 1865, Tashkent fell to the Russian Empire; as a result, it became the capital of Russian Turkestan. In Soviet Union, Soviet times, it witnessed major growth and demographic changes due to Population transfer in the Soviet Union, forced deportations from throughout the Soviet Unio ...

Sarygamysh Lake
Sarygamysh Lake, also Sarykamysh or Sary-Kamysh (, , , ), is the largest lake in Turkmenistan located about midway between the Caspian Sea and the Aral Sea. A quarter of the lake's area is in Uzbekistan. The Sarykamysh basin and the Sarykamysh delta of the Amu Darya river are physical and geographical nature regions of the Daşoguz Region of Turkmenistan. Up until the 17th century, the lake was fed by the Uzboy River, a distributary of the Amu Darya River, which continued on to the Caspian Sea. Today, its main source of water is a canal from the Amu Darya, but also the runoff water from surrounding irrigated lands, containing high levels of pesticides, herbicides and heavy metals. Etymology The name of the lake comes from the Turkic languages, Turkic words ''sari'' (yellow) and ''qamish'' (depression), a reference to the yellow color of silt and salt in the old dried up basin before its flooding by the Soviets. The modern Turkmenistan, Turkmen authorities wish to "Turkmenize" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
