Answer:
Agriculture at this time declined completely as it was affected by the economic movement that began to emerge.
Crops in these named countries were fundamental to the world, they even had very advanced mechanisms that promoted the production of quality food, for example in
Ethiopia's cultivation system was adapted to the northern mountainous areas and did not apply to any cultivation in other regions. The most famous member of this farming system was coffee, but one of the most useful plants was sorghum, a dryland cereal; teff was endemic to the region.
But this was not enough since the world economic movement made other countries become producers of the same products as the named countries, these countries having more capital and more technology were the ones that beat them in the competition of agriculture, exporting more to the world and making agricultural production fall in the countries where the question was named in the question.
Explanation:
This is a typical example of what we call economic-agricultural competition, where world countries have always exported or imported different products according to their needs. The exporting country always seeks to produce quality for the world and thus stay in the position of exporter.
Nowadays, in comparison with 1200, it is more difficult to maintain these world positions due to overpopulation, since not only good quality products must be exported, but also a good quantity.
This system that occurred many years ago is one of the methods to maintain the world economy and food, it is for something that preserves so much over time, with the disadvantage that the positions of those who export and those who are not dynamic and this generates that many Countries not considering exporters at certain stages have a drop in agricultural production.
