Feeding a rising world inhabitants has been a critical concern for many years, however right now there are new causes for alarm. Floods, warmth waves and different climate extremes are making agriculture more and more precarious, particularly within the Global South.
The struggle in Ukraine can be a issue. Russia is blockading Ukrainian grain exports, and fertilizer costs have surged due to commerce sanctions on Russia, the world’s main fertilizer exporter.
Amid these challenges, some organizations are renewing requires a second Green Revolution, echoing the introduction within the Nineteen Sixties and Seventies of supposedly high-yielding styles of wheat and rice into creating international locations, together with artificial fertilizers and pesticides. Those efforts centered on India and different Asian international locations; right now, advocates concentrate on sub-Saharan Africa, the place the unique Green Revolution regime by no means took maintain.
But anybody involved with meals manufacturing must be cautious what they want for. In latest years, a wave of recent evaluation has spurred a important rethinking of what Green Revolution-style farming actually means for meals provides and self-sufficiency.

As I clarify in my ebook, The Agricultural Dilemma: How Not to Feed the World, the Green Revolution does maintain classes for meals manufacturing right now – however not those which can be generally heard. Events in India present why.
A triumphal narrative
There was a consensus within the Nineteen Sixties amongst improvement officers and the general public that an overpopulated Earth was heading towards disaster. Paul Ehrlich’s 1968 bestseller, The Population Bomb, famously predicted that nothing might cease “hundreds of millions” from ravenous within the Seventies.
India was the worldwide poster little one for this looming Malthusian catastrophe: Its inhabitants was booming, drought was ravaging its countryside and its imports of American wheat have been climbing to ranges that alarmed authorities officers in India and the U.S.
Then, in 1967, India started distributing new wheat varieties bred by Rockefeller Foundation plant biologist Norman Borlaug, together with excessive doses of chemical fertilizer. After famine failed to materialize, observers credited the brand new farming technique with enabling India to feed itself.

Borlaug acquired the 1970 Nobel Peace Prize and continues to be extensively credited with “saving a billion lives.” Indian agricultural scientist M.S. Swaminathan, who labored with Borlaug to promote the Green Revolution, acquired the inaugural World Food Prize in 1987. Tributes to Swaminathan, who died on Sept. 28, 2023, at age 98, have reiterated the declare that his efforts introduced India “self-sufficiency in food production” and independence from Western powers.
Debunking the legend
The customary legend of India’s Green Revolution facilities on two propositions. First, India confronted a meals disaster, with farms mired in custom and unable to feed an exploding inhabitants; and second, Borlaug’s wheat seeds led to file harvests from 1968 on, changing import dependence with meals self-sufficiency.
Recent analysis exhibits that each claims are false.
India was importing wheat within the Nineteen Sixties due to coverage selections, not overpopulation. After the nation achieved independence in 1947, Prime Minister Jawaharlal Nehru prioritized creating heavy trade. U.S. advisers inspired this technique and provided to present India with surplus grain, which India accepted as low-cost meals for city staff.
Meanwhile, the federal government urged Indian farmers to develop nonfood export crops to earn overseas forex. They switched hundreds of thousands of acres from rice to jute manufacturing, and by the mid-Nineteen Sixties India was exporting agricultural merchandise.

Borlaug’s miracle seeds have been not inherently extra productive than many Indian wheat varieties. Rather, they only responded extra successfully to excessive doses of chemical fertilizer. But whereas India had considerable manure from its cows, it produced nearly no chemical fertilizer. It had to begin spending closely to import and subsidize fertilizer.
India did see a wheat growth after 1967, however there’s proof that this costly new input-intensive strategy was not the primary trigger. Rather, the Indian authorities established a new coverage of paying increased costs for wheat. Unsurprisingly, Indian farmers planted extra wheat and fewer of different crops.
Once India’s 1965-67 drought ended and the Green Revolution started, wheat manufacturing sped up, whereas manufacturing developments in different crops like rice, maize and pulses slowed down. Net meals grain manufacturing, which was rather more essential than wheat manufacturing alone, truly resumed on the similar development fee as earlier than.
But grain manufacturing grew to become extra erratic, forcing India to resume importing meals by the mid-Seventies. India additionally grew to become dramatically extra depending on chemical fertilizer.
According to knowledge from Indian financial and agricultural organizations, on the eve of the Green Revolution in 1965, Indian farmers wanted 17 kilos (8 kilograms) of fertilizer to develop a median ton of meals. By 1980, it took 96 kilos (44 kilograms). So, India changed imports of wheat, which have been nearly free meals help, with imports of fossil fuel-based fertilizer, paid for with valuable worldwide forex.
Today, India stays the world’s second-highest fertilizer importer, spending US$17.3 billion in 2022. Perversely, Green Revolution boosters name this excessive and costly dependence “self-sufficiency.”
The toll of ‘green’ air pollution
Recent analysis exhibits that the environmental prices of the Green Revolution are as extreme as its financial impacts. One purpose is that fertilizer use is astonishingly wasteful. Globally, solely 17% of what’s utilized is taken up by vegetation and finally consumed as meals. Most of the remainder washes into waterways, the place it creates algae blooms and lifeless zones that smother aquatic life. Producing and utilizing fertilizer additionally generates copious greenhouse gases that contribute to local weather change.
In Punjab, India’s prime Green Revolution state, heavy use of fertilizers and pesticides has contaminated water, soil and meals and endangered human well being.
In my view, African international locations the place the Green Revolution has not made inroads ought to take into account themselves fortunate. Ethiopia presents a cautionary case. In latest years, the Ethiopian authorities has compelled farmers to plant rising quantities of fertilizer-intensive wheat, claiming this can obtain “self-sufficiency” and even permit it to export wheat price $105 million this 12 months. Some African officers hail this technique as an instance for the continent.
But Ethiopia has no fertilizer factories, so it has to import it – at a value of $1 billion simply previously 12 months. Even so, many farmers face extreme fertilizer shortages.
The Green Revolution nonetheless has many boosters right now, particularly amongst biotech corporations which can be keen to draw parallels between genetically engineered crops and Borlaug’s seeds. I agree that it presents vital classes about how to transfer ahead with meals manufacturing, however precise knowledge tells a distinctly totally different story from the usual narrative. In my view, there are various methods to pursue much less input-intensive agriculture that will probably be extra sustainable in a world with an more and more erratic local weather.
