Kyiv vs Savannah

Informations

Kyiv or Kiev (Ukrainian: Київ) is the capital and most populous city of Ukraine. It is in north-central Ukraine along the Dnieper River. Its population in July 2015 has been 2,887,974 (though greater estimated numbers have been cited in the media ), making Kyiv the seventh-most populous city in Europe.Kyiv is an important industrial, scientific, educational and cultural center of Eastern Europe. It is home to many high-tech businesses, higher education institutions, and historical landmarks. The town has an extensive system of public transport and infrastructure, including the Kyiv Metro. The city's name is said to derive from the name of Kyi, one of its four legendary creators. During its history, Kyiv, one of the oldest cities in Eastern Europe, passed through several phases of prominence and obscurity. The city probably existed as a commercial centre as early as the 5th century. A Slavic settlement on the wonderful trade route between Scandinavia and Constantinople, Kyiv was a tributary of the Khazars, until its capture by the Varangians (Vikings) in the mid-9th century. Under Varangian rule, the town became a capital of the Kievan Rus', the first East Slavic state. Completely destroyed during the Mongol invasions in 1240, the city lost most of its influence for the centuries to come. It was a provincial capital of marginal value in the outskirts of the lands controlled by its powerful neighbours, first Lithuania, then Poland and Russia.

The city prospered again during the Russian Empire's Industrial Revolution in the late 19th century. In 1918, following the Ukrainian People's Republic declared independence from Soviet Russia, Kyiv became its capital. From 1921 onwards Kyiv was a town of Soviet Ukraine, which was proclaimed by the Red Army, and, from 1934, Kyiv was its capital. The town was almost completely ruined during World War II but quickly recovered from the postwar years, remaining Soviet Union's third-largest city. After the collapse of the Soviet Union and Ukrainian independence in 1991, Kyiv remained Ukraine's capital and experienced a steady influx of cultural migrants from different regions of the country. During the country's transformation into a market economy and electoral democracy, Kyiv has continued to be Ukraine's biggest and wealthiest city. Its armament-dependent industrial output fell after the Soviet collapse, adversely affecting science and technology, but new sectors of the economy such as services and finance facilitated Kyiv's increase in salaries and investment, as well as providing continuous funding for the development of housing and urban infrastructure. Kyiv emerged as the most pro-Western area of Ukraine; parties advocating tighter integration with the European Union dominate during elections.

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.
