The Green Revolution, spearheaded by Norman Borlaug, dramatically transformed global agriculture in the mid-20th century. This period saw a surge in crop production, particularly in wheat and rice, thanks to new, high-yielding varieties. However, “What Is The Green Revolution” beyond just increased yields is a question that demands deeper exploration, considering both its benefits and drawbacks.
Raymond C. Offenheiser, former president of Oxfam America and Distinguished Professor at Notre Dame, offers insights into Borlaug’s groundbreaking work and its complex legacy.

The Core of the Green Revolution: High-Yielding Varieties
Offenheiser defines the Green Revolution as the introduction of new crop varieties, mainly wheat and rice, capable of doubling or tripling production in countries like Mexico, India, and Pakistan. Borlaug’s dwarf wheat variety in Mexico served as a model for developing similar high-yielding crops worldwide. These new varieties significantly reduced malnutrition in Mexico and helped avert famines in India and Pakistan during the 1960s.
Borlaug’s Trailblazing Techniques: Redesigning the Plant
Borlaug’s genius lay in his ability to redesign the plant itself. He recognized that traditional wheat varieties with tall stalks were primarily focused on maximizing sunlight exposure. By developing a shorter, sturdier dwarf variety, the plant could support more grains on its head. A similar approach was adopted for rice at the International Rice Research Institute in the Philippines.
Norman Borlaug’s work in developing high-yielding wheat varieties significantly impacted global food production.
Furthermore, Borlaug developed a dwarf wheat variety adaptable to diverse environments, overcoming the limitations of traditional varieties sensitive to light, temperature, and other environmental changes. This adaptability was crucial for widespread adoption and impact.
Unintended Consequences: Environmental and Socioeconomic Impacts
While the Green Revolution dramatically increased food production, it also had unintended consequences. Offenheiser highlights that these new varieties required significant inputs of fertilizers and water to achieve their high yields.
Environmental Concerns
The reliance on fertilizers and pesticides led to environmental concerns, including soil and water pollution. Environmentalists criticized the intensified use of these crop varieties, fearing it would exacerbate pollution problems already seen in the United States.
Socioeconomic Disparities
The need for purchased inputs like fertilizers, pesticides, and access to irrigation created socioeconomic disparities. Only capitalized farmers could afford these inputs, leading to consolidation in the agricultural sector and, in some cases, displacement of the small farmers Borlaug initially intended to help. This disparity was more pronounced in Latin America than in Asia.
A Broader Critique: Evaluating the True Costs
The Green Revolution faced a broader critique, questioning its intentions and the need to consider environmental, social, political, and economic factors alongside productivity increases. The initial focus on simply boosting yields was challenged by a growing awareness of the interconnectedness of agricultural systems.
Borlaug’s Vision: Sustainable Development Before Its Time
Offenheiser points out that Borlaug’s background in forestry and plant pathology gave him a unique perspective on the convergence of environment, population, and food security. He was concerned with the broader food system and the need to balance productivity with environmental sustainability.
The Green Revolution transformed agricultural practices, but also raised concerns about sustainability and environmental impact.
Borlaug believed that increasing productivity on small plots of land would minimize deforestation and environmental damage. Ironically, Offenheiser notes that the modern food system is now seeing rapid deforestation for crops like soybeans, a trend Borlaug likely would have opposed.
Borlaug’s Legacy: A Humble Midwestern Agriculturalist
Offenheiser remembers Borlaug as a humble, down-to-earth Midwestern agriculturalist who remained grounded despite the global impact of his work. He took on the challenging task of developing a breeding program in Mexico, a country facing significant food challenges.
Borlaug’s ability to connect with farmers, understand their problems, and apply the best science of his era to solve those problems was a key to his success. He exemplified the sensibilities of the Depression generation, bringing a practical and problem-solving approach to agriculture.
The Green Revolution: A Complex Legacy
In conclusion, understanding “what is the green revolution” requires acknowledging its successes in increasing food production and averting famines. However, it’s equally crucial to recognize its unintended consequences, including environmental degradation and socioeconomic disparities. Borlaug’s vision of sustainable development, although ahead of its time, remains relevant today as we strive to create a food system that is both productive and environmentally responsible. The lessons learned from the Green Revolution inform ongoing efforts to develop more sustainable and equitable agricultural practices.
