Green Revolution

Definition

The Green Revolution refers to a period of significant agricultural transformation that began in the 1940s and continued into the late 1960s, marked by the introduction of high-yielding varieties of crops, advanced agricultural techniques, and increased use of fertilizers and pesticides. This movement aimed to enhance food production globally, particularly in developing countries, to combat hunger and improve food security.

5 Must Know Facts For Your Next Test

1. The Green Revolution began in Mexico in the 1940s, with Norman Borlaug leading efforts to develop high-yield wheat varieties that dramatically increased production.
2. This movement led to a significant rise in food production in developing countries, particularly in Asia and Latin America, helping to alleviate famine and hunger in those regions.
3. The widespread use of chemical fertilizers and pesticides during the Green Revolution raised concerns about environmental impacts, including soil degradation and water pollution.
4. Irrigation infrastructure improvements were a key component of the Green Revolution, allowing for better water management and crop productivity in arid regions.
5. While the Green Revolution increased food availability, it also contributed to social inequalities, as wealthier farmers could afford the necessary inputs while smaller farms struggled.

Review Questions

• How did the introduction of high-yield varieties during the Green Revolution impact global food production?
  • The introduction of high-yield varieties during the Green Revolution significantly boosted global food production by providing crops that produced more grains per plant. This change was crucial for many developing countries facing food shortages, allowing them to increase their harvests and support growing populations. The improved crop yields played a vital role in reducing hunger and improving food security in regions that had previously struggled with agricultural output.
• What are some environmental concerns associated with the agricultural practices promoted during the Green Revolution?
  • The agricultural practices promoted during the Green Revolution, such as the extensive use of chemical fertilizers and pesticides, raised several environmental concerns. These practices led to soil degradation, contamination of water sources, and loss of biodiversity due to monoculture cropping systems. As a result, there are ongoing discussions about the sustainability of these methods and their long-term effects on ecosystems.
• Evaluate the social implications of the Green Revolution on rural communities in developing countries.
  • The Green Revolution had significant social implications for rural communities in developing countries. While it increased food production and alleviated hunger for many, it also deepened economic disparities. Wealthier farmers who could afford high-quality seeds and inputs thrived, whereas smallholder farmers often fell behind due to a lack of resources. This division created tensions within communities and highlighted issues related to land ownership and access to agricultural technology.
