From lost biodiversity to corporate control: Unmasking the myths of the green revolution in India

By Bharat Dogra
 
The Green Revolution has long been celebrated as a turning point in Indian agriculture, but it is time to re-examine this legacy with a clearer lens. While touted as a scientific breakthrough that saved millions from hunger, the revolution’s deeper impacts—on biodiversity, soil health, farmer independence, and long-term sustainability—paint a far more complex picture.
At its core, the Green Revolution was driven by the introduction of exotic seed varieties that were designed to respond well to high doses of chemical fertilizers and pesticides. These so-called “high-yielding varieties” (HYVs)—better termed High Response Varieties (HRVs)—were promoted as necessary for increasing food production. But this narrative ignored a wealth of indigenous knowledge and traditional seed varieties that had evolved over generations to thrive in local conditions, often without chemical inputs.
What was sidelined—sometimes deliberately—was the fact that many traditional varieties could deliver comparable, if not better, yields using eco-friendly and low-cost methods. The Green Revolution led to the erosion of this biodiversity. Thousands of indigenous crop varieties, nurtured by farmers across centuries, began vanishing from the fields. Instead of building on this rich agricultural heritage, policy and research fixated on a narrow technological path—one that often brought profits to large agribusinesses but high costs to farmers and the environment.
The Yield Myth
Contrary to popular belief, the Green Revolution did not always result in a dramatic boost in yields. Data from the 12th Five-Year Plan of India provides a revealing comparison of agricultural productivity before and after the Green Revolution. From 1951–52 to 1967–68, crop yields were already improving significantly. In fact, the average annual growth in rice, wheat, jowar, maize, and cotton yields during this pre-Green Revolution era was in several cases higher than during the subsequent period from 1968–69 to 1980–81. For instance, maize yields grew at 4.8% annually before the Green Revolution, but only 1.7% after. Overall, the value of output for many non-horticultural crops declined in the post-Green Revolution period despite massive inputs.
Lost Alternatives and Suppressed Innovation
What makes this trajectory even more tragic is that promising, eco-friendly innovations were underway in India just as the Green Revolution was being promoted. At the Central Rice Research Institute (CRRI), a remarkable technique—clonal propagation of rice—was being developed under the guidance of Dr. R.H. Richharia. This method, based on the use of genetically diverse indigenous rice varieties, showed immense potential for increasing productivity sustainably.
Dr. Richharia’s work, even published in the prestigious journal Nature in 1962, was gaining traction across research centers in India. But this promising line of innovation was systematically dismantled in favor of Green Revolution technologies imported from international institutions. Years later, Dr. Richharia recalled with anguish how CRRI was pressured to abandon its indigenous program and instead adopt the international dwarf rice varieties. His opposition, rooted in national interest and scientific integrity, was ignored.
By 1979, the harm of this narrow approach had become evident. A government task force on rice breeding, led by Dr. Richharia, acknowledged the grave risk posed by the narrow genetic base of Green Revolution rice varieties. It warned of increased vulnerability to pests and diseases and the unsuitability of these HYVs for most of India’s rice-growing regions. Yet, these warnings went largely unheeded.
A Lesson in Policy Priorities
The Green Revolution reflects a broader pattern: policy and research that prioritize corporate and international interests over local needs and sustainability. Indigenous knowledge systems and self-reliant farming methods were marginalized, while large agribusinesses benefited from subsidies and government support.
Farmers lost not only their traditional seeds but also a measure of autonomy. Today, multinational corporations increasingly control seed technologies, often building their patents on genetic material that once belonged to the commons. This shift has serious implications for food sovereignty and the future of farming.
Looking Forward: A Call for Agro-Ecology
India stands at a crossroads. The myths of the Green Revolution must be dismantled—not to dismiss its contributions entirely, but to recognize its deep flaws and missed opportunities. The future lies in promoting agro-ecological practices that build on India’s vast heritage of crop diversity and local knowledge. This includes supporting small and medium farmers through affordable, sustainable, and environmentally responsible technologies.
As we confront climate change, soil degradation, and rural distress, our policies must center on the long-term well-being of both farmers and ecosystems. This requires moving away from a one-size-fits-all model of agriculture and toward an inclusive, ecologically balanced vision rooted in our own agricultural heritage.

A comrade in culture and controversy: Yao Wenyuan’s revolutionary legacy

By Harsh Thakor*  This year marks two important anniversaries in Chinese revolutionary history—the 20th death anniversary of Yao Wenyuan, and the 50th anniversary of his seminal essay "On the Social Basis of the Lin Biao Anti-Party Clique". These milestones invite reflection on the man whose pen ignited the first sparks of the Great Proletarian Cultural Revolution and whose sharp ideological interventions left an indelible imprint on the political and cultural landscape of socialist China.

What's behind Donald Trump's 'narco-state' accusation against Venezuela

By Manolo De Los Santos  The US government has revived its campaign to label Venezuela a "narco-state", accusing its top leadership of drug trafficking and slapping hefty bounties on their heads for capture. This campaign, which only momentarily took a backseat, is a strategic fabrication, not a factual assessment. This accusation, particularly amplified under the Trump Administration, is a calculated smokescreen to justify a long-standing agenda: the overthrow of the Venezuelan government and the seizure of its vast oil and mineral resources. A closer examination of the facts reveals a country that has actively fought drug trafficking on its own terms and a US government with a clear and consistent history of destabilizing independent countries in Latin America.

Two more "aadhaar-linked" Jharkhand deaths: 17 die of starvation since Sept 2017

Kaleshwar's sons Santosh and Mantosh Counterview Desk A fact-finding team of the Right to Feed Campaign, pointing towards the death of two more persons due to starvation in Jharkhand, has said that this has happened because of the absence of aadhaar, leading to “persistent lack of food at home and unavailability of any means of earning.” It has disputed the state government claims that these deaths are due to reasons other than starvation, adding, the authorities have “done nothing” to reduce the alarming state of food insecurity in the state.

1857 War of Independence... when Hindu-Muslim separatism, hatred wasn't an issue

"The Sepoy Revolt at Meerut", Illustrated London News, 1857  By Shamsul Islam* Large sections of Hindus, Muslims and Sikhs unitedly challenged the greatest imperialist power, Britain, during India’s First War of Independence which began on May 10, 1857; the day being Sunday. This extraordinary unity, naturally, unnerved the firangees and made them realize that if their rule was to continue in India, it could happen only when Hindus and Muslims, the largest two religious communities were divided on communal lines.

New RTI draft rules inspired by citizen-unfriendly, overtly bureaucratic approach

By Venkatesh Nayak* The Department of Personnel and Training , Government of India has invited comments on a new set of Draft Rules (available in English only) to implement The Right to Information Act, 2005 . The RTI Rules were last amended in 2012 after a long period of consultation with various stakeholders. The Government’s move to put the draft RTI Rules out for people’s comments and suggestions for change is a welcome continuation of the tradition of public consultation. Positive aspects of the Draft RTI Rules While 60-65% of the Draft RTI Rules repeat the content of the 2012 RTI Rules, some new aspects deserve appreciation as they clarify the manner of implementation of key provisions of the RTI Act. These are: Provisions for dealing with non-compliance of the orders and directives of the Central Information Commission (CIC) by public authorities- this was missing in the 2012 RTI Rules. Non-compliance is increasingly becoming a major problem- two of my non-compliance cases are...

Epic war against caste system is constitutional responsibility of elected government

Edited by well-known Gujarat Dalit rights leader Martin Macwan, the book, “Bhed-Bharat: An Account of Injustice and Atrocities on Dalits and Adivasis (2014-18)” (available in English and Gujarati*) is a selection of news articles on Dalits and Adivasis (2014-2018) published by Dalit Shakti Prakashan, Ahmedabad. Preface to the book, in which Macwan seeks to answer key questions on why the book is needed today: *** The thought of compiling a book on atrocities on Dalits and thus present an overall Indian picture had occurred to me a long time ago. Absence of such a comprehensive picture is a major reason for a weak social and political consciousness among Dalits as well as non-Dalits. But gradually the idea took a different form. I found that lay readers don’t understand numbers and don’t like to read well-researched articles. The best way to reach out to them was storytelling. As I started writing in Gujarati and sharing the idea of the book with my friends, it occurred to me that while...

Ground reality: Israel would a remain Jewish state, attempt to overthrow it will be futile

By NS Venkataraman*  Now that truce has been arrived at between Israel and Hamas for a period of four days and with release of a few hostages from both sides, there is hope that truce would be further extended and the intensity of war would become significantly less. This likely “truce period” gives an opportunity for the sworn supporters and bitter opponents of Hamas as well as Israel and the observers around the world to introspect on the happenings and whether this war could have been avoided. There is prolonged debate for the last several decades as to whom the present region that has been provided to Jews after the World War II belong. View of some people is that Jews have been occupants earlier and therefore, the region should belong to Jews only. However, Christians and those belonging to Islam have also lived in this regions for long period. While Christians make no claim, the dispute is between Jews and those who claim themselves to be Palestinians. In any case...
