Questions: The Green Revolution: Technology and Food Production

Question 1

Norman Borlaug won the Nobel Peace Prize in 1970 for his work developing high-yielding wheat varieties. Why was a Peace Prize awarded for agricultural science?

Model answer: The Nobel Committee awarded Borlaug the Peace Prize — not the science prize — because his high-yielding dwarf wheat varieties, combined with fertilizers and irrigation, dramatically increased wheat production in Mexico, India, and Pakistan in the 1960s, helping avert famines that population forecasters had predicted as inevitable. The Committee reasoned that averting mass starvation contributed to world peace. By 1968, India had become wheat self-sufficient; Pakistan followed. Estimates suggest the Green Revolution may have saved over a billion people from starvation.

The selection of the Peace Prize was deliberate: food security and famine prevention were understood as prerequisites for political stability and peace. The Cold War context also mattered — the US government supported Green Revolution research partly to prevent famine-driven Communist movements in developing countries.

Question 2

The Green Revolution increased total food production but was criticized for failing to address food insecurity at the household level. Why?

• A. Because Green Revolution crops were less nutritious than traditional varieties
• B. Because production gains primarily benefited wealthy farmers who could afford inputs, while poor farmers were disadvantaged
• C. Because all Green Revolution crops were exported rather than consumed locally
• D. Because the technology only worked in temperate climates

Answer: (B)

High-yielding varieties required purchased inputs — fertilizers, pesticides, irrigation — that required capital. Wealthier farmers with land collateral could access credit for these inputs and capture productivity gains; smaller and poorer farmers often could not. The Green Revolution thus increased inequality within farming communities. Amartya Sen's analysis of famines argues that food insecurity is primarily about access and entitlement, not total production — even with increased output, people without income to buy food go hungry.

Question 3

What was the 'Punjab crisis' in India, and what does it reveal about the long-term sustainability of Green Revolution agriculture?

Model answer: Punjab, India's most productive Green Revolution state, experienced severe agricultural sustainability problems by the 1990s-2000s: groundwater tables fell dramatically due to intensive irrigation; soils degraded from chemical overuse; fertilizer requirements increased as soils lost natural fertility; pesticide-resistant pests emerged. Farmers faced rising input costs and declining marginal returns. This 'treadmill' dynamic — where maintaining yields requires ever-increasing inputs — is a systemic problem of Green Revolution agriculture's dependence on external chemical inputs rather than soil ecology management.

The Punjab crisis is a key case study in environmental history showing how short-term production gains from technological intensification can create long-term sustainability problems. Similar dynamics have emerged in other Green Revolution regions.

Question 4

The Green Revolution preserved traditional crop biodiversity by introducing improved varieties.

• T. True
• F. False

Answer: False

The Green Revolution had the opposite effect on biodiversity. Replacing thousands of traditional local varieties with a handful of high-yielding varieties dramatically reduced crop genetic diversity — a process called 'genetic erosion.' Traditional varieties represented millennia of local adaptation to specific soil, climate, and pest conditions. When farmers switched to standardized high-yielding varieties, these locally-adapted varieties were abandoned. This loss of biodiversity increases vulnerability: a single pathogen or climate change could devastate monoculture crops in ways it could not affect the diverse portfolio of traditional varieties.

Question 5

In what regions did the Green Revolution have the least impact, and why?

Model answer: Sub-Saharan Africa largely missed the Green Revolution for several reasons: the region's highly variable soils and complex agro-ecologies were less amenable to standardized high-yielding varieties; African agriculture relied heavily on diverse subsistence crops (sorghum, millet, root crops) rather than wheat and rice; infrastructure for distributing inputs and marketing surpluses was weak; African countries were poorer and had less capacity to subsidize inputs. A second generation of agricultural development programs — including the Alliance for a Green Revolution in Africa (AGRA) — has attempted to bring similar gains to Africa since the 2000s, with contested results.

The Green Revolution's regional imbalance illustrates that agricultural technology transfer is not automatic — it requires appropriate institutional, infrastructural, and ecological conditions.
