5.3 The Green Revolution

• What was the main goal of the Green Revolution?

  Enhance food security
• One key development of the Green Revolution was the introduction of high-yielding varieties (HYVs) of crops such as wheat
• The Green Revolution saw an increased use of chemical fertilizers and pesticides.
• What type of systems were expanded during the Green Revolution to support increased crop production?

  Irrigation
• Match the farming feature with its type during the Green Revolution:

  Crop Varieties ↔️ High-yielding varieties (HYVs)

  Fertilization ↔️ Chemical fertilizers

  Pest Control ↔️ Chemical pesticides

  Irrigation ↔️ Large-scale systems
• The Green Revolution introduced mechanized equipment and advanced techniques
• The Green Revolution significantly increased agricultural productivity in developing countries.
• What type of crop varieties were introduced during the Green Revolution?

  High-yielding varieties (HYVs)
• Organic manure was used for fertilization during the Green Revolution.

  False
• Chemical pesticides were used to control pests
• What were some key technologies introduced during the Green Revolution?

  High-yielding crop varieties
• Large-scale irrigation systems were a feature of the Green Revolution.
• What type of seeds were used in traditional farming?

  Low-yielding, native seeds
• The Green Revolution expanded the use of irrigation systems.
• Manual labor and simple tools were characteristic of traditional farming.
• What type of crop varieties were used in the Green Revolution?

  High-yielding varieties (HYVs)
• Match the feature with its farming type:

  Manual labor, simple tools ↔️ Traditional Farming

  Mechanized equipment, advanced techniques ↔️ Green Revolution
• What replaced organic manure in the Green Revolution for fertilization?

  Chemical fertilizers
• The Green Revolution significantly increased agricultural productivity in developing countries.
• What type of crop varieties were used in traditional farming?

  Low-yielding, native seeds
• The Green Revolution relied on mechanized equipment and advanced techniques.
• What were some positive impacts of the Green Revolution?

  Increased food production
• The Green Revolution helped reduce hunger and malnutrition in many regions.
• What was the main goal of the Green Revolution?

  Reduce famine and enhance food security
• Order the key developments of the Green Revolution:

  1️⃣ Introduction of HYVs

  2️⃣ Increased use of fertilizers and pesticides

  3️⃣ Expansion of irrigation systems

  4️⃣ Improved agricultural management practices
• The Green Revolution primarily focused on developed countries.

  False
• The Green Revolution led to improved food security worldwide.
• How did the Green Revolution increase crop yields?

  High-yielding varieties (HYVs)
• Rice production in Asia nearly tripled between 1960 and 1990 due to the Green Revolution.
• One negative impact of the Green Revolution was its reliance on chemical fertilizers.
• What was the main goal of the Green Revolution?

  Increase food production
• Crop yields increased dramatically due to high-yielding varieties, fertilizers, and irrigation
• The Green Revolution significantly reduced hunger by increasing food availability.
• Higher incomes for farmers improved their living standards and overall quality of life
• How much did rice production in Asia increase between 1960 and 1990?

  Nearly tripled
• Increased use of fertilizers and pesticides led to environmental degradation
• The Green Revolution resulted in a loss of traditional crop varieties due to the focus on high-yielding varieties.
• Steps leading to water overuse during the Green Revolution

  1️⃣ Expansion of irrigation systems

  2️⃣ Over-extraction of groundwater
• What is the environmental impact of fertilizers and pesticides?

  Soil degradation, water pollution
• Match the feature of the Green Revolution with its environmental impact:

  Fertilizers & Pesticides ↔️ Soil degradation, water pollution

  High-Yielding Varieties ↔️ Loss of biodiversity

  Irrigation Systems ↔️ Water overuse, groundwater depletion
