Sub-Saharan Africa PPT, Part 2: The Hometown of Black People

Location:

South of the Sahara Desert, it is bounded by the Atlantic Ocean to the west and the Indian Ocean to the east.

The terrain of sub-Saharan Africa is dominated by plateaus

Most of this area belongs to the middle ___ zone of the five zones, and the climate types are:

_____________climate,

_____________climate,

_____________climate,

_____________climate,

_____________climate.

This area is dominated by ________ climate, ___________ climate and ________ climate. Among them, ________ climate types are the most widely distributed.

What are the characteristics of the savannah climate? What natural disasters does this climate often lead to?

Tip: The savanna area is clearly divided into dry and wet seasons, and the wind and precipitation in the dry and wet seasons are obviously different. In the wet season, the wind comes from the ocean and there is abundant precipitation; in the dry season, the wind comes from the inland and there is little rain. In some years, the dry season is extended and the wet season is shortened, or there are several consecutive years of drought, which can easily lead to severe drought, resulting in poor agricultural harvests and a "food problem." Therefore, the natural cause of the increasingly serious food problems in sub-Saharan Africa is drought caused by the savanna climate.

sahara desert

The Sahara Desert is the largest desert in the world outside of Antarctica. It is located in northern Africa. It has extremely harsh climate conditions and is one of the most unsuitable places on earth for biological growth. It is located south of the Atlas Mountains and the Mediterranean Sea (about 35° north latitude) and north of about 14° north latitude (250 mm isohyet), starting from the Atlantic coast in the west and ending in

The shores of the Red Sea. It traverses the northern part of the African continent, with a length of 5,600 kilometers from east to west and a width of about 1,600 kilometers from north to south, with a total area of ​​approximately 9,065,000 square kilometers, accounting for approximately 32% of the total area of ​​Africa.

The Sahara Desert divides the African continent into two parts, North Africa and southern Black Africa. The climate and culture of these two parts are completely different. The southern boundary of the Sahara Desert is a semi-arid savanna, which is called "Sahel" in Arabic. To the south is southern Africa, which has abundant rain and luxuriant plants. It is called "Sudan" in Arabic, which means black Africa.

The political struggle of the people of sub-Saharan Africa is divided into three stages:

The first stage: From the 15th century to the 20th century, colonialism frantically plundered black people and natural resources and products.

Second stage: After World War II, national liberation struggles flourished and many countries became independent.

The third stage: After independence, many countries are gradually getting rid of the shackles of the colonial economy and developing their own national economies.

Sub-Saharan Africa PPT, Part 3: Economy dominated by a single commodity

What is a single-commodity economy?

An economy that relies too much on the production of one or more primary products.

Think about what a single commodity economy looks like?

Tip: This region has been subject to political aggression and economic control and exploitation by colonialists for a long time, which is the fundamental reason for the formation of the "single commodity economy" in this region.

African efforts:

1. Efforts should be made to reduce the population and control the spread of the disease.

2. Increase the domestic industrial structure to enhance the ability to resist risks in the international market.

3. Vigorously develop the country's independent industries to reduce dependence on foreign industrial products.

4. Establish a regional international cooperation organization - the Union of African States - to jointly resist international risks.

5. Strengthen South-South cooperation.

Sub-Saharan Africa PPT, Part 4: Population, Food and Environment

According to statistics, the global AIDS death toll in 2002 was 5 million, 3.5 million from African countries, and Botswana is the country with the worst AIDS situation in the world. Maun, a town with a population of 70,000, is the heartland of Botswana's AIDS epidemic and the area with the highest incidence of AIDS in the world. Botswana's official statistics report states that 48% of the country's citizens are infected with HIV. A local priest said: AIDS is not easily transmitted and is mainly transmitted through sexual intercourse. As the economy and contact with the outside world suddenly developed in the area, alcoholism and crime rates also increased, and the locals believed in the value of carpe diem. Later, the priest took us to the cemetery in the town, where hundreds of new graves were added and there was a putrid smell. Most of the deceased were born in the 1970s and died between 2001 and 2003. The town's cemetery has been filling up quickly, and young people are dying one after another. Many old people think it is a witch bringing disaster, but young people know that disasters are mainly spread through promiscuous sexual behavior.

Tip: The population of sub-Saharan Africa is growing too fast, exceeding the food and economic growth rate, which has constituted an increasingly serious population and food problem.

question. Overpopulation is one of the important causes of food problems. The rapid growth of the population requires more food and meat. However, the increased production of food and meat cannot meet the needs of the rapid population growth, which limits economic development. In order to maintain survival, people are deforestation and reclaiming grasslands to plant food crops. Or overgrazing in grassland areas causes loss of soil fertility and expansion of desertification. To solve these problems, we must control the population growth rate, protect the natural environment, and improve the level of agricultural and animal husbandry production. Controlling excessive population growth and improving population quality; mitigating natural disasters and protecting the ecological environment; vigorously developing food production and solving food shortages have become the three important tasks of this region in the future.
