But during the dry season, weather can be extremely hot, and rainfall will amount to only four inches each month. Some rivers and streams Unreliable rainfall in the future will also play a big part in any crisis over water resources, but frustratingly again for scientists, it is much harder to make confident predictions about rain than it is about temperature. Tropical forests have exceptionally high animal and plant species. Humans create savannas by burning grasslands and cutting down trees so they can plant crops. edition, Washington, D.C. 1999.All commercial rights reserved. The Surprising Role of CO2 in Changes on the African Savanna Recent studies show that many of the world’s savannas, including famed southern African landscapes, are experiencing significant change as rising levels of carbon dioxide in the atmosphere favor the growth of trees over grasslands. In West Africa The African Savanna has a wet, dry climate. C). enough. trees can only grow in the wet season.To survive the dry

In tropical savanna climates, the dry season can become severe, and often drought conditions prevail during the course of the year.
savanna climate there is a distinct dry season, which is The suggested afforestation of large areas of Africa to mitigate climate change will destroy valuable ecological, agricultural, and tourist areas, while doing little to reduce global CO2 levels.This is the view of 46 scientists from around the world -- many of whom are leading scientists in Africa -- in a Technical Comment published in the journal The Technical Comment is a critique of another recent paper in Using remote sensing and machine learning to estimate the amount of atmospheric carbon that could be sequestered by global tree restoration, the Bastin study highlighted large tracts of land in southern Africa -- and the tropics in general -- as potential sites for large scale afforestation in efforts to fight against climate change. Higher tree cover in Namibian and Botswanan savannas is considered degradation by the people living there.

Its Köppen climate group is Aw. The average temperature Savanna biome has a wet/dry climate. Large animals, like elephants, can turn a forest into a savanna by knocking trees down, stripping the bark from the trees, and tramping on tree seedlings. Many plants tend to shrivel up and die during the winter, which is a real problem to the Africans that depend on farm-grown crops. According to the reports' authors, it is not only maize crops which are likely to benefit from the warmer temperatures, but malarial mosquitoes, causing increased epidemics of Africa's biggest killer, and introducing the disease to altitudes above 2,000 metres, which have so far been considered out of harm's way.
Finally, tree planting in grasslands and savannas, as proposed by the Swiss researcher team, is damaging to the environment as ancient grasslands and savannas contain immense biodiversity and provide services to humanity, such as livestock forage and groundwater recharge.The group of scientists' main concern is that a myopic focus on tree planting will retract from the real issue of fighting climate change through reducing CO2 emissions and reduce the capacity of people to adapt to climate change while distracting from efforts to conserve intact ecosystems and reduce fossil fuel consumption.
