Savannah vs Donetsk

Informations

A savanna or savannah is a mixed woodland-grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests. The South American savanna types cerrado sensu stricto and cerrado dense typically have densities of trees similar to or higher than that found in South American tropical forests, with savanna ranging from 800–3300 trees per hectare (trees/ha) and adjacent forests with 800–2000 trees/ha.

Similarly Guinean savanna has 129 trees/ha, compared to 103 for riparian forest, while Eastern Australian sclerophyll forests have average tree densities of approximately 100 per hectare, comparable to savannas in the same region.Savannas are also characterised by seasonal water availability, with the majority of rainfall confined to one season; they are associated with several types of biomes, and are frequently in a transitional zone between forest and desert or grassland. Savanna covers approximately 20% of the Earth's land area.

Donetsk (UK: don-YETSK, US: də-N(Y)ETSK; Ukrainian: Донецьк [doˈnɛtsʲk] (listen); Russian: Донецк [dɐˈnʲetsk]), formerly known as Aleksandrovka, Hughesovka, Yuzovka, Stalin and Stalino (see also: cities' alternative names), is an industrial city in eastern Ukraine located on the Kalmius River in the disputed Donetsk region. While internationally recognized as in Ukraine, the city is under the de facto administration of the unrecognized Donetsk People's Republic, which claims it as its capital city. The population was estimated at 929,063 (2016 est.) in the city core, with over 2,000,000 in the metropolitan area (2011). According to the 2001 Ukrainian Census, Donetsk was the fifth-largest city in Ukraine.Administratively, Donetsk has been the centre of Donetsk Oblast, while historically, it is the unofficial capital and largest city of the larger economic and cultural Donets Basin (Donbass) region. Donetsk is adjacent to another major city, Makiivka, and along with other surrounding cities forms a major urban sprawl and conurbation in the region. Donetsk has been a major economic, industrial and scientific centre of Ukraine with a high concentration of heavy industries and a skilled workforce. The density of heavy industries (predominantly steel production, chemical industry, and coal mining) determined the city's challenging ecological situation. In 2012 a UN report ranked Donetsk among the world's fastest depopulating cities.The original settlement in the south of the European part of the Russian Empire was first mentioned as Aleksandrovka in 1779, during the reign of the Empress Catherine the Great.

In 1869 the Welsh businessman John Hughes founded a steel plant and several coal mines in the region, and the town was named Hughesovka or Yuzovka (Юзовка) in recognition of his role ("Yuz" being a Russian-language approximation of Hughes). During Soviet times, the city's steel industry expanded. In 1924 Yuzovka was renamed Stalin. In 1929 Stalin was renamed Stalino, and in 1932 the city became the centre of the Donetsk region. Renamed Donetsk in 1961, the city today remains a centre for coal mining and for the steel industry. Since April 2014 Donetsk and its surrounding areas have been one of the major sites of fighting in the ongoing Donbass War, as pro-Russian separatist forces battle against Ukrainian military forces for control of the city and surrounding areas. Throughout the war, the city of Donetsk has been administered by the pro-Russian separatist forces as the center of the Donetsk People's Republic (DPR), with outlying territories of the Donetsk region divided between the two sides. Donetsk International Airport became the epicenter of the war with almost a year-long battle leading to massive casualties among civilians and a total ruination of the northwestern neighborhoods of the city. As of July 2020, the DPR has full control of the city, with Ukrainian and DPR forces still engaging in combat outside of the city.
