Human induced land use change has a greater effect on savanna structure and NPP than any other environmental changes. Savannas generally have low human population density as their capacity to support intensive agriculture and livestock grazing are poor; however, population pressure and land-use changes are likely to be greater here than in other biomes over the coming decades. The agro-pastoral communities in savannas are highly dependent on the natural vegetation, which is vulnerable to degradation. Strong social and economic forces will continue to force the conversion of forests to savannas and grasslands to pasture or agriculture fields, although tourism is supporting conservation of large areas of savannas in Africa.
Cattle rearing has been occurring for more than 6000 years in India and Africa and was sustainable before more recent increases in population, changing social practices, colonialisation, war, extensive commercial ranching, etc. Shifting cultivation has also been practised for thousands of years, generally in areas with rainfall greater than 700mm, but this is being affected by reduced fallow periods, larger commercial operations and increased use of fertiliser and irrigation which increases short-term productivity but can lead to long term depletion of resources and environmental degradation. South American savannas are rapidly being transformed for soybean cultivation and cattle raising. Australian savannas are likely to remain as grazing lands as alternative economic land uses are limited (Young & Solbrig, 1993; Solbrig, 1996; Joe Scanlan, pers. comm.).
Humans influence savannas by managing fire, wildlife and domestic livestock, and wood and grass removals. Intensive livestock grazing, exclusion of indigenous browsers and fire prevention leads to rapid bush encroachment. In areas of high population and charcoal production, intensive wood harvesting leads to decreased woody biomass, which, combined with high grazing, leads to erosion. The same happens when fire frequency is increased and the animal load is too high (Young & Solbrig, 1993).
The main producers in a savanna biome are grasses, shrubs, and some trees. These plants have adaptations to survive in the dry conditions and periodic wildfires common in savannas. They provide the foundation of the food chain for animals in the savanna biome.
Approximately 20% of the Earth's land area is covered by savanna biome, making it one of the largest biomes in the world. Savannas are characterized by a mix of grasses and scattered trees, and are found in tropical and subtropical regions.
The biome that has animals such as zebras, lions, rhinoceroses, and owls is the savanna biome. This biome is characterized by grasslands with scattered trees and shrubs, making it an ideal habitat for grazing animals and predators. Owls are typically found in the savanna due to the abundance of prey and suitable nesting sites.
These are the Biomes: * Temperate Deciduous Forest * Desert * Tundra * Rain Forest * Grasslands (Savanna and Prairie) * Taiga, Boreal, Coniferous Forest ( They are all kinda the same things, look up images of them, and then you will understand) * Aquatic Biomes ( Marine, Fresh Water, and Estuary) * Those are the Biomes names * (:
A savanna is a biome that has weird weather:D happy now that i used biome in asentence..
what are good impacts humans have on the savanna biome
There is no such thing as a savanna desert. The savanna is a semi-arid biome that is a transition zone between a desert and another biome, such as a grassland.
It is a savanna biome or grassland
The savanna is a distinct biome as is the desert. There is no 'savanna desert.'

The Human activies on the savanna has reduced the size of the natural land. The villiges and towns have cleared part of the savanna for houses and streets and gardens, which takes away many of the nutrients out of the ground and not allowing the natural biome to grow back. Humans have taken the many savannas and because of our activities turned much of it to desert. most likely in the future the savanna will be no more. with the way we clear it and the pollutants we put into the environment the savanna will be reduced to nothing.
Cheetahs inhabit a grassland (savanna) biome.

Yo ma!
