3. Research conducted by scientists led to significant advancements in irrigation techniques, enabling farmers to cultivate arid and semi-arid lands effectively.
4. The work of scientists during the Green Revolution has been credited with saving millions from starvation, especially in countries facing food shortages.
5. However, some scientists have raised concerns about the environmental impact and sustainability of the practices promoted during the Green Revolution.

Review Questions

• How did scientists contribute to the development of high-yielding varieties of crops during the Green Revolution?
  • Scientists contributed significantly by researching and breeding high-yielding varieties (HYVs) of crops such as wheat and rice. Through a combination of traditional breeding techniques and scientific methodologies, they were able to create new strains that could produce more grain per plant. This research helped address food shortages in various regions and was fundamental in transforming agricultural practices during this period.
• Evaluate the positive and negative impacts that scientists' contributions during the Green Revolution had on global agriculture.
  • The contributions of scientists during the Green Revolution had several positive impacts, such as drastically increasing food production and helping to prevent famine in many developing countries. However, there were also negative consequences, including increased reliance on chemical fertilizers and pesticides, which can harm the environment. Additionally, the focus on a few high-yield crops may have led to a loss of biodiversity in agricultural systems.
• Discuss how the role of scientists in the Green Revolution reflects broader trends in science and technology's influence on societal issues like food security.
  • The role of scientists in the Green Revolution illustrates how science and technology can profoundly influence societal issues such as food security. By applying scientific research to agriculture, they not only increased crop yields but also addressed urgent challenges like hunger and malnutrition. This reflects a broader trend where scientific advancements are utilized to solve complex global problems. However, it also highlights the need for careful consideration of long-term effects and sustainability when implementing technological solutions.
