What causes the Subsistence farmers of Latin America to use Slash and Burn Agriculture?

What caused the Inca to create Terraces?

What caused the Aztec to create Chinampas?

Answers

Answer:

The slash and burn agriculture is used because of lack of development and bad treatement of the soil.

The Incan terraces were created so that the steep slopes can be used for agriculture.

The Aztec chinampas were created to maximize production by using the surface of the water as a basis because of the huge demand and limited resources.

Explanation:

In multiple parts of Latin America, the people use slash and burn techniques for agriculture. This technique consists of cutting down and burning the vegetation in order to open up space for agriculture. This is done in countries that are not well developed, so nature is not taken into consideration, nor the agricultural land is treated properly so it quickly becomes useless.

The Incas were people with big ingenuity, and this was also seen in their agricultural practices. They predominantly lived in high mountainous areas with very steep slopes, but that didn't stop. In order to make use of the terrain and satisfy the demand for food, the Incas carved the steep slopes horizontally and made terraces, on which they were able to produce a lot of food.

The Aztecs lived in an area that had a very high population density, so the demand for food was very big, but the land and fertile soil were limited. In order to solve the problem, they came up with the chinampas. The chinampas were basically made up of floating gardens, small and easy, filled with fertile soil, and having access to water all the time because they were on the surface of a lake. The production levels were very high with this technique.

Answers

Answer:

The Baltic states in Eastern Europe have become a region of interest because of their market economy.

Explanation:

The Baltic states, all three of them, were part of the Soviet Union. When they gained independence, they were the first to quickly move and make big steps to transform their societies to democracies and to have market economies. This was done because they despised the system in which they forcefully were included, but also to become as close as possible to the Western World.

All three, Estonia, Latvia, and Lithuania, managed to develop quickly and as planned, and they were soon on the radar of the Western countries as places for investment and trade. Also, seening the progress that they make and willingness to move away and secure themselves from Russia, the European Union and NATO all made these three states their members, aiding big strategic advancement for these organization, and safety and prosperty for the Baltic states.
