Tanzania's Climate
Tanzania represents a wealth of ecological diversity, ethnic diversity, and geographical diversity. It contains both the tallest mountain in Africa as well as the largest lake, and is a tourist hotspot for safaris and expeditions to Mt. Kilimanjaro. The citizens of Tanzania are utterly dependent on the weather for their two major businesses, agriculture and tourism. Thus, the climate of Tanzania is worth examining in greater detail.
Tanzania has two distinct seasons, wet and dry. However, the northern region of Tanzania can experience two wet seasons, the longest of which spans from March to May and the shortest from November to December. The March to May period is known as “the long rains”, during which excessive rainfall occurs. The shorter period from November to December is known as “the short rains”, where rainfall occurs intermittently and may last into January. The rest of the country experiences one wet season from November to May. Since Tanzania is located in the Southern hemisphere, December to March can be considered the country’s summer, and June to September its winter.
The seasons are “in fact the transition between the two main trade wind systems which dominate at different times of the year; the northeasterly trades between December and March, and the southeasterlies between June and September” (Sumner 53-66). Caused by the highly cyclic weather patterns of the intertropical convergence zone, these trade winds are the main factor in determining the change of seasons and are abetted by the very geography of Tanzania. The flow of air over the East African plateau causes the formation of the Southerly Jet which in turn regulates the Indian monsoon season. The jet flows in parallel to Ta...

...does not bode well for its inhabitants. If remedial measures are not taken, Tanzania’s economy and quality of life will suffer greatly in the near future, and we as a planet will suffer greater consequences in the far future due to the rising temperature of the Earth.

Water scarcity is a crucial issue in a country called Djibouti. Djibouti lies in “The Horn of Africa” which is a peninsula in Northeast Africa. However, due to climate change and variability, refugees from Somalia and poverty, Djibouti is now considered an extremely water poor country. The aim of this report is to inform the government about the water crisis in Djibouti and that climate change is one of the main factors that cause it.
Not only is it ridiculously hot year round, but Africa has vast wildlife. One great example is an occurrence where John and thousands of refugees were trapped on the banks of the Gilo River. They had Ethiopian soldiers on one side and a crocodile filled river on the other. As John started to hear grenades being launched, he saw many soldiers and vehicles. He had no choice but to jump into the river, face the vicious crocodiles, and “attempt” to swim ten minutes without having the physical skills to do so.
In a straight forward manner, the author shows in vivid details that a game of climate change is on a real roll. May be in a few years, the island nations like Indonesia may sink, food belts of Bangladesh destroy and countries and states set over their river system. The whole scenario projects that sooner or later the whole world could end up in famines, floods and wars; wars with political grudges on environment. This means we, the desperate people, will all land up fighting even for our basic resources i.e., food, water and energy. A change of 1.5oC instead of 2oC in global temperature would certainly be a reason of joy but if it is 2-2.5oC, impacts may be havocking.
The most common sites of malaria-carrying mosquitoes is in tropical and subtropical areas with warm climates. Also, there must be a source of water, such as a lake, ocean, or stream, because this is where the mosquitoes breed. While Africa is the site of most malaria cases, there are a few other countries that account for some of the malaria cases. In fact, in 1990, seventy-five percent of all recorded malaria cases outside Africa were condensed in nine countries, which were India, Brazil, Afghanistan, Sri Lanka, Thailand, Vietnam, Cambodia, Indonesia, and China. There was once a small malaria epidemic in the United States. It occurred mainly in Army families. This was because U.S. troops in other countries were not on the proper medication, contracted the disease, and brought it back to the United States.
According to the World Health Organization; there are about up to 20 different known locally important species of anopheles around the world. All of the vector species feed at night. But although all Anopheles mosquitoes need a body of stagnant water to breed, each species has its particular breeding preference; for example some prefer small and shallow collections of fresh water, such as rice fields, or the Oshana’s in Southern Africa. We find that the transmission rate is more concentrated in areas where the parasite has a chance at surviving longer (The parasite needs a long life span so the parasite has sufficient time to replicate and mature and to complete its growth inside the mosquito).Infection concentration is also found to be more in areas where the vector favors feeding on humans as opposed to other animals. For example, most published research suggests that the resilient human-biting habit and long lifespan of the Africa...
Hello Coach Willaim’s, i am going to tell you about African savannas. Im at The savannas in Kenya, Africa. Savannas have warm temperature throughout the year. There really isn't a difference in the Savannas seasons. Savannas has a very long dry season which is during the winter, and a very wet season which is during summer.
From the economy to its culture Kenya has felt the devastating results of the ...
Kakadu is often described as having 2 seasons. The ‘wet’ and the ‘dry’. This is caused by a monsoon, a seasonal reversal in wind direction.
In this essay I will outline the ways in which the international community has failed to respond to climate change in the right way, specifically looking at the effect that climate change has had on poor countries and their peoples. The international community has failed to address climate change in a way that is effective in helping not only those in the developed world but also those in poor countries. The irony of global warming is that developed countries that contribute most to it are often in areas that are least effected by the consequences and yet they have the most power to combat the effects. In contrast poor countries, such as pacific island countries (PICs) and those in the arctic, are often situated in areas that are most effected
My first article, “Study Finds Pattern of Severe Droughts in Africa” which I retrieved from The New York Times, written by Andrew C. Revkin on April 17, 2009, has the main point that Sub- Saharan Africa is home to tens of millions of the world’s poorest people as said by climate researchers. Most of Africa’s 390 million people live off of less then a $1.25 a day. These people’s lives depend on the quality of the land and rainfall. Kevin Watkins, director of Human Development Reports of the United Nations, says, “Even small climate blips such as a delay in rains, a modest shortening of the drought cycle, can have catastrophic effects”. Timothy M. Shanahan of the University of Texas and Jonathan T. Overpeck of the University of Arizona have warned that global warming that is caused by human exposure of greenhouse gases is a major reason for droughts in Africa. Major droughts have also been linked to pattern increases and reductions in surface temperatures of the Atlantic Ocean. In 1972 to about 1974, Ethiopia’s human population was about 31 million; from 31 million, one million died due to t...
One concept that became apparent in this unit was how climate change has had such a dramatic effect on the island of Kiribati and its people. Climate change in Kiribati is allegedly associated with the environmental pollution and chemical by-products of other nations such as Australia, England, China, and the United States. Evidence has been presented showing the Kiribati Island is at risk of vanishing as a result of the monstrous waves in the South Pacific Ocean. However, even though the United States is one of the largest known sources of extreme gas emissions, we cannot only blame it and the other developed countries. We must look also to the government of the Kiribati itself, which has done little to decrease their
Mali is an African country. It is located in the hot desert in West Africa. The capital is Bamako .Mali has different type of Climate: tropical climate in the south and arid climate in the north. Droughts are frequent and the rainfall all over the country is negligible. It has two main seasons, the wet season from June to October and the cool and hot dry season the remainder of the year. We find some species of trees such as the doom palm, the baobab, and leguminous fruit bearing plants.
The Sahara’s climate is very hot and dry. Although it is very hot during the day, it does become cold at night. On average, it only has 8 inches of rainfall per year. The Sahara's climate consists of b...
Tanzania is a multi-purpose destination. From fabulous game parks, the richest in animals in the whole of Africa, to the opportunity of experiencing the ‘Snows of Kilimanjaro’ personally, the hustling and bustling metropolis of Dar Es Salaam, to dream islands in the Indian Ocean, Tanzania proves to be absolutely rich in diversity.
