Unsustainable short-term improvements in agricultural productivity

Other Names:
Misguided green revolution
Negligent disregard of environmental consequences of forced growth in agriculture

The very things that made the Green Revolution so stunning - that made the last doubling in agricultural productivity possible - now cause trouble. Efforts to improve agricultural productivity in the short-term are often designed to succeed at the expense of long-term sustainability, whether this takes the form of ecological stress, loss of genetic diversity in standing crops, salinization and alkalization of irrigated lands, nitrate pollution of ground-water, or pesticide residues in food.


The doubling of agricultural yields experienced earlier this century required an eightfold increase in the use of nitrogen fertilizers and thirtyfold increases in the application of potash and phosphorus. In some places, additional applications of fertilizer are no longer economically feasible because they produce only fractionally higher yields.

At the beginning of the 21st century, the states of Punjab and Haryana are on the edge of a grave environmental crisis. They were at the forefront of the Green Revolution in the late 1960s and early 1970s, in which farm machinery, pesticides and fertilizers, irrigation and the replacement of traditional crops with high-yielding varieties dramatically increased productivity. The two states together provide 80 percent of India's food supply. But the land is increasingly unable to support this burden of intensive agriculture. Crop yields and water resources are declining alarmingly, and some parts are close to becoming barren. Many farmers are heavily in debt from their investments in new equipment and reliance on chemicals, and rural unemployment is increasing. In the wheat belt of Ludhiana, Punjab, heavy use of fertilizer has caused excess nitrates to leach into the groundwater, posing hazards for human health. Without massive change towards more sustainable agriculture, say using less-intensively farmed sorghum and millet, there is little doubt that this food basket of India will collapse within a decade, placing the country's population at great risk of famine.


The Green Revolution and its technologies, short term or otherwise, helped prevent widespread famine throughout Asia at least.

Counter Claim:

The Green Revolution only provided immediate solutions, thereby compounding the long term problem.
