Analysis of causes of food shortage problem

1. Demographic reasons:

Rapid population growth, deforestation, land reclamation, and overgrazing have led to land desertification.

3. Climatic conditions:

Under the influence of the tropical grassland climate, some seasons are long and the wet season is short, resulting in drought and food harvest loss.

summary:

1 Location in the world: The part of Africa south of the Sahara Desert.

2Sea and land location: Indian Ocean to the east and Atlantic Ocean to the west.

3. Three important latitudes: the Tropic of Cancer passes through the north, the equator passes through the middle, and the Tropic of Cancer passes through the south.

4. Latitude position: Most of them are between the Tropic of Cancer and the Tropic of Cancer.

5Climate: Climate types are symmetrically distributed from north to south with the equator as the center. Savannah climates are the most widespread.

6 Location in the Five Belts: Most are located in the tropics.

7 main terrain areas: Congo Basin, East African Plateau, South African Plateau, Ethiopian Plateau.

8Terrain: Mainly plateau, known as "Plateau Continent".

9Main rivers: Congo River, Nile River.

1 Mineral resources: Diamond and gold production and reserves rank first in the world.

2 Abundant tropical cash crops: coffee, cocoa, oil palm, etc.

3. Economic development: Due to the long-term colonial rule, the economic development was slow and dominated by a single commodity economy. It exports primary agricultural and mineral products and imports industrial manufactured products, putting it at a disadvantage.

4 Population, food, and environment: Population is growing faster than food—famine—deforestation, overgrazing—water and soil erosion, land desertification—resulting in reduced food production— --famine, poverty

5 solutions:

1. Control the population size and improve the quality of the population.

2. Change the single commodity economic structure and develop the economy rapidly.

3. Use land rationally and protect the environment.
