AP Human Geography

Definition

The Green Revolution refers to a period of agricultural transformation that began in the mid-20th century, characterized by the introduction of high-yielding varieties of crops, the use of chemical fertilizers and pesticides, and advancements in irrigation techniques. This revolution significantly increased food production in many developing countries, particularly in Asia and Latin America, and played a crucial role in addressing global hunger and food security issues.

5 Must Know Facts For Your Next Test

  1. The Green Revolution began in the 1940s and gained momentum in the 1960s, with major contributions from scientists like Norman Borlaug, who is often called the 'Father of the Green Revolution.'
  2. It primarily focused on staple crops such as wheat and rice, leading to dramatic increases in crop yields in countries like India and Mexico.
  3. While it successfully reduced hunger in many regions, the Green Revolution also led to negative environmental impacts, including soil degradation and water scarcity due to overuse of fertilizers and irrigation.
  4. The Green Revolution was not uniform; its success varied by region and socio-economic context, leading to increased disparities between wealthy and poor farmers.
  5. The advances made during the Green Revolution paved the way for ongoing agricultural research and technology, including biotechnology and genetically modified organisms (GMOs).

Review Questions

  • How did the introduction of high-yielding varieties impact food production during the Green Revolution?
    • The introduction of high-yielding varieties (HYVs) was a cornerstone of the Green Revolution that significantly boosted food production. These genetically improved strains of crops were engineered to resist diseases and produce more grain per plant. As a result, countries like India saw wheat and rice yields increase dramatically, helping to alleviate hunger for millions. However, this shift also required substantial inputs of water and agrochemicals, which had mixed effects on sustainability.
  • Evaluate the environmental consequences of the Green Revolution's agricultural practices.
    • The environmental consequences of the Green Revolution were significant and multifaceted. While it succeeded in increasing food production, the heavy reliance on chemical fertilizers and pesticides led to soil degradation, reduced biodiversity, and contamination of water sources. Additionally, extensive irrigation practices contributed to water scarcity issues in some regions. These negative impacts highlight the need for sustainable agricultural practices that balance productivity with environmental health.
  • Assess how the Green Revolution influenced social structures within agrarian societies.
    • The Green Revolution had profound effects on social structures within agrarian societies by altering land ownership patterns and income distribution. Wealthier farmers who could afford new technologies gained significantly from increased yields, while poorer farmers often struggled with debt due to the costs of inputs like seeds and fertilizers. This created a divide between rich and poor farmers, exacerbating social inequalities. Furthermore, as agriculture became more mechanized, there was a shift in labor dynamics that impacted rural communities and traditional farming practices.
