12.3. Africa

industry

farms

Africa, together with the islands belonging to it (the largest of them is Madagascar) has an area of ​​30.3 million sq. km, the population is more than 750 million people.

In terms of the size of its territory, Africa surpasses all other large regions of the world, and in terms of the main indicators of economic and social development, it is significantly inferior to them. Africa ranks last in terms of industrialization, transport availability, health and science development, crop yields and livestock productivity.

In the international division of labor, Africa is represented by the products of the extractive industry, branches of tropical and subtropical agriculture. Its share is especially large in the world production of gold and diamonds, uranium and bauxite, phosphorites, coconuts in palm oil, coffee and cocoa.

Some geographic features of the region:

1. Among other continents, Africa occupies a special geographical position. The equator crosses it almost in the middle and divides it into two parts, approximately equally located (to the north and south) in the equatorial, tropical and subtropical latitudes. Therefore, a huge amount of heat enters the entire territory of Africa evenly throughout the year, and the seasons in its northern and southern parts opposite: while in the northern hemisphere it is summer, in the southern hemisphere it is winter.

The nature of the geographical position provides the possibility of year-round navigation off the coast of Africa, since the seas washing it do not freeze.

The Strait of Gibraltar separating Africa and Europe (its distance is only 14 km) and the Suez Canal connecting the Mediterranean and Red Seas are of great importance for shipping. Many African countries are landlocked.

2. Africa is ahead of all other regions of the world in terms of pace natural growth population (more than 3% per year), as it stands out for its high birth rate. However, Africa is the region with the highest mortality rates. As a result, the age structure of the population is characterized by a high proportion (about 45%) of children and adolescents under 15 years of age.

With an average density of 25 people per 1 sq. km, the population is distributed very unevenly across Africa. The most densely populated are the sea coasts, coastal regions of South Africa, Zambia, Zaire and Zimbabwe. In these areas, the population density ranges from 50 to 1000 people per 1 sq. km. In the vast areas of the Sahara, Kalahari, Namib deserts, the population density barely reaches 1 person per 1 sq. km.

Despite the world's highest rates of urbanization, Africa lags behind other regions in terms of the share of urban population (about 30%).

Linguistically, half of the African population belongs to the Niger-Kordofan family, and a third to the Afrozian family. Residents of European descent make up only 1%.

3. Africa is characterized by significant population migration (external and internal). The main centers of attraction work force from the African continent are Western Europe and Western Asia (especially the Gulf countries). Within the continent, migration flows of labor mainly go from the poorest countries to the richer ones (South Africa, Nigeria, Cote d'Ivoire, Libya, Morocco, Egypt, Tanzania, Kenya, Zaire, Zimbabwe).

4. On political map Africa is represented by 55 states, the overwhelming majority of which are developing countries. The only economically developed country is South Africa. Among the countries, the overwhelming majority are republics (with the exception of Morocco, Lesotho and Swaziland, which are constitutional monarchies). The administrative-territorial structure of states, with the exception of South Africa and Nigeria, is unitary.

5. Geopolitically and economically, Africa is divided into two parts: North Africa and Tropical Africa.

North Africa includes an area (about 10 million square kilometers with a population of 160 million people) adjacent to the Mediterranean, inhabited mainly by Arabs professing Islam. The countries located on this territory (Algeria, Egypt, Western Sahara, Libya, Mauritania, Morocco, Tunisia), thanks to their geographic location(seaside, neighboring countries Southern Europe and Western Asia) and a higher (in comparison with the states of Tropical Africa) level of economic and industrial development, are distinguished by greater involvement in the international division of labor (export of oil, gas, phosphorites, etc.). Tropical Africa includes the territory located south of the Sahara, within which, in turn, Western, Central, East and South Africa are distinguished. The overwhelming majority of the population of the countries located on their territory belongs to the equatorial (Negroid) race. Ethnic composition The population is very diverse (there are more than 200 peoples), multinational states prevail. The main sphere of activity of the population is agriculture (with the exception of the countries of South Africa, in whose economy industry and the service sector play a decisive role). Tropical Africa is the most economically backward, least industrialized and least urbanized part of the developing world. Of the 49 countries within its borders, 32 belong to the group of "least developed countries of the world". Average per capita GNP in the countries of Eastern, Western and Central Africa several times (5-7 or more times) less than in the countries of North and South Africa.

Economy: minerals, leading industries

industry

Extractive industries dominate in Africa's industry, the share of manufacturing industries is small, and many branches of modern industry (precision engineering, instrument making, machine tool construction, etc.) are generally absent.

Among other continents, Africa ranks first in reserves of diamonds, gold, platinum, manganese, chromite, bauxite and phosphorite. There are large reserves of coal, oil and natural gas, copper, iron, uranium, cobalt ores.

The main branches of the extractive industry are developed in the places of occurrence of the largest and most well-developed minerals:

South Africa is distinguished by the concentration of reserves and mining of coal (South Africa), gold (South Africa, Zaire, Zimbabwe, Tanzania) and diamonds (Zaire, South Africa, Botswana), manganese, chromium (South Africa), iron (Angola), copper (Zaire, Zambia and South Africa) and uranium (South Africa, Namibia) ores;

North Africa - phosphorites (Morocco, Algeria »Tunisia), oil and natural gas (Algeria, Libya);

West africa- bauxite (Guinea, Ghana, Cameroon), oil (Nigeria), iron (Mauritania, Liberia, Gabon) and uranium (Niger) ores.

The mining industry in Africa is weakly connected with other sectors of the economy, most of its products are exported. A few branches of heavy industry (smelting copper, alumina and aluminum, the production of phosphorus and nitrogen fertilizers, mining equipment, the oil refining industry, etc.) occupy a very modest position in the economy of African countries.

Among the branches of the manufacturing industry, the textile and food industries have received the greatest development. Leading industries textile industry- production of cotton fabrics (Egypt, Sudan, Algeria), food - production of vegetable oils (palm, peanut, olive), coffee, cocoa, sugar, wine, canned fish.

Economy: natural conditions, leading agricultural sectors

farms

The prevailing flat relief (the Atlas, Futa-Djallon, Cape and Drakonov mountains are located only on the outskirts of the continent), a high supply of thermal resources (the sum of active temperatures is 6,000-10,000 ° C), the presence of fertile soils (red-yellow, black, brown soil equatorial forests, brown soils of subtropics, alluvial soils of river valleys), vast natural pastures (areas of savannas, steppes and semi-deserts occupy about half of Africa's area) are favorable for various types of agricultural activities.

However, the conditions of moisture supply significantly limit the possibilities for the development of agriculture in this region. In almost 2/3 of Africa's territory, sustainable agriculture is possible only with land reclamation. In the equatorial region of Africa, where the amount of precipitation is 1500 mm or more per year, there is an excess of moisture, in the semi-deserts and deserts of the northern and southern hemisphere(Sahara, Namib, Kalahari) - on the contrary, its lack. The most favorable natural conditions for agriculture are the windward slopes of the Atlas and Cape Mountains, the Mediterranean regions, the eastern marginal regions of South Africa, where the amount of precipitation is 800-1000 mm per year.

The leading branch of agriculture in Africa is crop production. In the structure of crop production, two areas are distinguished: the production of food crops for local consumption and the production of export crops.

Crops consumed in African countries include millet, sorghum, rice, wheat, corn, cassava (or cassava), yams, and sweet potatoes (yams).

The main grain crops of the African continent, millet and sorghum, are cultivated almost everywhere. Corn is the main food crop of the savannah zone. Wheat crops are concentrated in North Africa and South Africa. Rice is mainly grown in well-humid regions of East Africa (Nile Valley, Madagascar, etc.) - The scale of wheat and rice production does not cover the domestic needs of the region, so many African countries import wheat and rice.

The main export crops of Africa are coffee, cocoa, tea, cotton, peanuts, bananas, agave (sisal). Most of the coffee production is provided by Ethiopia and the Republic of Cote d "Ivoire, cocoa beans - Ghana and the Republic of Cote d" Ivoire, raw cotton - the countries of East Africa (Egypt, Sudan, Uganda, Tanzania, Mozambique), peanuts - Nigeria, Senegal.

Africa is a major supplier of coconut kernels and palm oil and olives to the world market. The oil palm is a culture of West and Equatorial Africa. The olive tree grows mainly in the countries of North Africa (Tunisia and others). The countries of North and South Africa produce citrus fruits (oranges, tangerines, lemons, grapefruits, etc.), tea, tobacco, and grapes.

Livestock production is characterized by low productivity. Nomadic, semi-nomadic and distant pasture animal husbandry prevails. The main branches of animal husbandry are sheep (wool and meat and wool), cattle (mainly meat), camel breeding.

Transport. Length railways small - vehicles cover more significant territories. For some countries of Central and East Africa, the internal water transport... In terms of length and intensity of use, the basins of the Congo, Nile and Niger rivers stand out.

External transportation is carried out by sea transport. More than 90% of exports of African countries are mineral and agricultural raw materials and food. The main export items are oil (Nigeria, Libya, Algeria), copper (Zambia, Zaire), iron ore(Liberia, Mauritania), manganese ores (Gabon), phosphorites (Morocco), uranium (Niger, Gabon), cotton (Egypt, Sudan, Chad, Mali, Tanzania, etc.), coffee (Ethiopia, Angola, Rwanda, Burundi and etc.), cocoa beans (Cote d "-Ivoire, Ghana, Nigeria, etc.), peanuts (Senegal, Gambia, Sudan), olive oil (Tunisia, Morocco), tobacco (Malawi, etc.), citrus fruits, grape wines (Algeria, Tunisia, etc.).

African countries mainly import machinery and equipment, manufactured goods, and foodstuffs.

Africa, together with the islands belonging to it (the largest of them is Madagascar) has an area of ​​30.3 million sq. km, the population is more than 750 million people.

In terms of the size of its territory, Africa surpasses all other large regions of the world, and in terms of the main indicators of economic and social development, it is significantly inferior to them. Africa ranks last in terms of industrialization, transport availability, health and science development, crop yields and livestock productivity.

In the international division of labor, Africa is represented by the products of the extractive industry, branches of tropical and subtropical agriculture. Its share is especially large in the world production of gold and diamonds, uranium and bauxite, phosphorites, coconuts in palm oil, coffee and cocoa.

Some geographic features region:

1. Among other continents, Africa occupies a special geographical position. The equator crosses it almost in the middle and divides it into two parts, approximately equally located (to the north and south) in the equatorial, tropical and subtropical latitudes. Therefore, a huge amount of heat enters the entire territory of Africa evenly throughout the year, and the seasons in its northern and southern parts are opposite: while in the northern hemisphere it is summer, in the southern hemisphere it is winter.

The nature of the geographical position provides the possibility of year-round navigation off the coast of Africa, since the seas washing it do not freeze.

The Strait of Gibraltar separating Africa and Europe (its distance is only 14 km) and the Suez Canal connecting the Mediterranean and Red Seas are of great importance for shipping. Many African countries are landlocked.

2. Africa is ahead of all other regions of the world in terms of natural population growth (more than 3% per year), as it stands out for its high birth rate. However, Africa is the region with the highest mortality rates. As a result, the age structure of the population is characterized by a high proportion (about 45%) of children and adolescents under 15 years of age.

With an average density of 25 people per 1 sq. km, the population is distributed very unevenly across Africa. The most densely populated are the sea coasts, coastal regions of South Africa, Zambia, Zaire and Zimbabwe. In these areas, the population density ranges from 50 to 1000 people per 1 sq. km. In the vast areas of the Sahara, Kalahari, Namib deserts, the population density barely reaches 1 person per 1 sq. km.

Despite the world's highest rates of urbanization, Africa lags behind other regions in terms of the share of urban population (about 30%).

Linguistically, half of the African population belongs to the Niger-Kordofan family, and a third to the Afrozian family.

Residents of European descent make up only 1%.

3. Africa is characterized by significant population migration (external and internal). The main centers of attraction for labor from the African continent are Western Europe and Western Asia (especially the countries of the Persian Gulf). Within the continent, migration flows of labor mainly go from the poorest countries to the richer ones (South Africa, Nigeria, Cote d'Ivoire, Libya, Morocco, Egypt, Tanzania, Kenya, Zaire, Zimbabwe).

4. Africa is represented on the political map by 55 states, the overwhelming majority of which are developing countries. The only economically developed country is South Africa. Among the countries, the overwhelming majority are republics (with the exception of Morocco, Lesotho and Swaziland, which are constitutional monarchies). The administrative-territorial structure of states, with the exception of South Africa and Nigeria, is unitary.

5. Geopolitically and economically, Africa is divided into two parts: North Africa and Tropical Africa.

North Africa includes an area (about 10 million square kilometers with a population of 160 million people) adjacent to the Mediterranean, inhabited mainly by Arabs who profess Islam. The countries located on this territory (Algeria, Egypt, Western Sahara, Libya, Mauritania, Morocco, Tunisia), due to their geographical position (coastal, neighboring in relation to the countries of Southern Europe and Western Asia) and higher (in comparison with the states Tropical Africa) level of economic and industrial development, are more involved in international division labor (export of oil, gas, phosphorites, etc.). Tropical Africa includes the territory located south of the Sahara, within which, in turn, Western, Central, East and South Africa are distinguished. The overwhelming majority of the population of the countries located on their territory belongs to the equatorial (Negroid) race. The ethnic composition of the population is very variegated (there are more than 200 peoples), multinational states prevail. The main sphere of activity of the population is agriculture (with the exception of the countries of South Africa, in whose economy industry and the service sector play a decisive role). Tropical Africa is the most economically backward, least industrialized and least urbanized part of the developing world. Of the 49 countries within its borders, 32 belong to the group of "least developed countries of the world". The per capita GNP in the countries of East, West and Central Africa is several times (5-7 times or more) less than in the countries of North and South Africa.
