Zorluk: ZorThe Columbian Exchange

Source: Official report by a local Qing dynasty magistrate in the Sichuan province of southwestern China, late eighteenth century.

"Formerly, the mountain slopes were covered with dense forests and deep grass, which held the rainwater. But since the arrival of the crop known as maize (*yumi*), migrant settlers have cleared the forests and burned the underbrush to plant it. Maize grows well in sandy, dry soils where rice cannot be cultivated. However, after only a few harvests, the soil is exhausted, and when the heavy rains come, the earth washes down into the valleys, choking the rivers and causing disastrous floods in the lowlands."

Which of the following historical processes in the period 1450 to 1750 is most directly reflected in the magistrate's report?

  1. A
    The incorporation of East Asian agricultural production into the commercial networks of the Triangular Trade.
  2. B
    The adoption of mercantilist policies by the Qing government to promote cash-crop exports at the expense of staple food production.
  3. The global diffusion of American food crops, which supported demographic growth but also placed new pressures on the environment.Cevap
  4. D
    The displacement of traditional peasant agriculture by European joint-stock companies establishing export-oriented plantations.

Cevap

The correct answer is the option stating that the report reflects the global diffusion of American food crops, which supported demographic growth but also placed new pressures on the environment.
The correct answer identifies that the cultivation of maize in China is a direct result of the global diffusion of American crops during the Columbian Exchange. These crops allowed Chinese farmers to utilize marginal lands, such as hillsides, which supported a massive population increase during the Qing dynasty but simultaneously caused significant ecological damage, including deforestation, erosion, and floods.

Adım Adım Çözüm

1
Analyze the historical context of the crop mentioned in the source.
The source discusses the cultivation of maize (*yumi*) in China. Maize is an American crop introduced to Afro-Eurasia through the Columbian Exchange.
This establishes the biological link between the Americas and East Asia, confirming the relevance of the Columbian Exchange.
2
Examine the ecological and demographic consequences described in the magistrate's report.
Peasants planted maize on cleared mountain slopes where rice could not grow. This led to soil exhaustion, erosion, and lowland flooding.
This demonstrates that the introduction of high-yield American staple crops expanded agricultural land use into marginal regions, causing environmental disruption.
3
Evaluate the distractors against historical evidence.
The Triangular Trade, European plantation joint-stock companies, and mercantilist export schemes are historically inaccurate descriptions of internal Qing dynasty peasant agricultural developments.
This eliminates incorrect choices that conflate distinct Atlantic economic systems or imperial practices with Chinese domestic ecology.
