Grasslands are very sensitive to disturbances, such as people hunting and killing key species, or plowing the land to make more space for farms. Explore strategies to mitigate the human impact on biomes. Land development drives animals away from populated areas and changes the conditions of the environment. Some animals that roam the Savanna include elephants, wild dogs, hyenas, zebras, lions, mice, vultures, cheetahs termites, and crocodiles. For example, in the drier parts of the African savanna, overgrazing by goats and cattle has removed most of the vegetation that holds the soil in place. They sustain a lot of plant and wildlife. Rainforest. There are many threats which assail the grassland biome of Savanna, most of which are caused first and foremost by humans and their actions towards this place (most of which are explained in Effects and impact of human progress), although there are still several threats which are caused without any (or with little) human involvement. Desertification means that the land is increasingly dry, losing much of its plant life and water. Human Impact. The primary threats are land cover‐change and transformation, landscape fragmentation that disrupts herbivore communities and fire regimes, climate change and rising atmospheric CO 2 . Human Impact on the Tropical Savanna There are two major issues of human interaction on the savanna. Fires are a big part of the human impact caused on the savanna biome. This statement is particularly true of the Earth's tropical savannas. Humans have a relatively negative impact on the savanna biome through desertification and tourism. Also humans being in the grasslands increase the chance of fires.

They also play a crucial role in regulating the global climate, for example by storing lots of carbon. The savanna covers about half of the surface of Africa and is a large biome in australia and parts of Asia and South America too. Humans live in this biome and affect it immensely. *Grasslands are sadly being threatened by human impacts. Humans have killed predators, built dwellings, and cleared land to be able to farm. However, the increased tourism has had some positive impacts, such as increased conservation efforts, according to the BBC. Human Impact on the Grasslands. Human Impact on the savanna. Dividing up the land for farming is bad because the animals of the grasslands don't have any way to move around. It has a distinct wet and dry season. Humans also impact upon the environment of the Savanna by trying to control it. On the other side people view humans as a helping source for the environment such as conserving endangered animals of the grasslands. Some positive impacts that humans have had on the savanna is, humans are starting to develop more and more perserves and wildlife parks, that are protecting animals from hunters and giving them natural space which are being destroyed by tourism and urban developments. To feed a growing human population, most of the world's grasslands, including the American prairies, are converted from natural landscapes to fields of corn, wheat or other crops.

Temperate grasslands have hot summers and cold winters. Tropical savannas are indeed a curious biome, neither grassland nor forest, but one in which two contrasting life forms—C 3 trees and C 4 grasses—compete for dominance in the face of limited resource availability and frequent disturbances such as fire and herbivory. They are being hunted by poutchers and their habitats are being destroyed by the furthering of the human environment. Some streams and rivers also dry up.

The people living in this biome are mainly farmers who grow cereals and other plants that can resist long dry spells, such as millet, sorghum, barley and wheat, as well as peanuts, cotton, rice and sugarcane, while breeding prevails in drier savannah areas. Logging makes the rainforest lose up to 137 plant and animal species every day just from deforestation. Peoples of the African savannah. Because grazing and fire are strongly affected by human activities and have been for thousands of years, humans continue to have a controlling influence on the nature, dynamics, development, structure, and distribution of savannas in many parts of their global range. Extinction of animals in this biome is caused by humans releasing foreign species into the savanna. Grasslands are threatened by habitat loss, which can be caused by human actions, such as unsustainable agricultural practices, overgrazing, and crop clearing. The increased use of the savanna by humans has caused degradation of this biome. In the dry season, dry grasses can be fuel for the fires. With the advent of human settlements in some savanna areas, controlled burns may be used for land clearing and cultivation. The trees and animals have less space to be so the population decreases with the land, making everything smaller. Human Impact Humans impact the Grassland Savanna by lessening the area of the land by making new space for industrialization. Humans also lead many successful conservation associations protecting our wildlife and maintaining a balance. Human Impacts & Conservation Savannas are subject to natural wildfires during dry seasons, but humans often cause fires as well. They stop the fires which would naturally clear the land, keep out certain animals which should naturally be there and remove grass and some of the few trees which grow there.
