“Father of the Green Revolution in India”: The Man, the Myth, the Legend: MS Swaminathan

MS Swaminathan Research Foundation, Chennai, Tamil Nadu, India
November 26, 2013

I can’t think of a better way to wrap up my research than visiting the MS Swaminathan Research Foundation in the southern coastal city of Chennai.  Almost since the beginning of my time in India, I had been hoping to meet and interview Dr. MS Swaminathan himself.  He is known as the “Father of the Green Revolution in India” and worked with the original “Father of the Green Revolution” (American Norman Borlaug), as well as the late and former prime minister Indira Gandhi in the 1960s to double India’s grain production, transforming the hungry nation from food insecure to a self-sufficient net exporter of food.  I should note that the Green Revolution in and of itself is controversial for a variety of reasons including:

·         The development of high yielding varieties of hybrid wheat demanded increased inputs of chemical pesticides, fertilizers, and irrigation to maintain performance, which has environmental ramifications (e.g. degraded soil, diminishing water table, resistance in pests and weeds)
·         The health consequences such as increased rates of cancer from exorbitant chemical applications
·         The social effects of causing indebtedness among farmers who were forced to adopt HYVs and rely on expensive external inputs from the market, thus exacerbating the issue of farmer suicides
·         The nutritional consequences in that people were consuming less traditional/coarse/nutritional grains such as millet and instead began consuming more wheat and rice
·         The consequences on biodiversity and a reduction in the crop gene pool as a large number of farmers stopped saving indigenous seeds and after adopting HYVs, many these traditional seed varieties have since disappeared (and biodiversity of seed is crucial for resilience in the era of climate change)

By no means is this an exhaustive list.  However, we cannot ignore that the Green Revolution probably saved India from widespread famine.  As stated though, we must consider the entire picture when assessing its status.  Needless to say, Dr. MS Swaminathan is a bit of a foodie/ag celebrity in my mind, so I was shocked and exhilarated when his secretary was able to arrange an interview.  In fact, he doesn’t usually meet or do interviews with students, so I was elated.  Especially because I made the big trip all the way to Chennai just to see him!  According to Wikipedia, “From 1972 to 1979 he was director general of the Indian Council of Agricultural Research. He was minister of Agriculture from 1979 to 1980. He served as director general of the International Rice Research Institute (1982–88) and became president of the International Union for the Conservation of Nature and Natural Resources in 1988.  In 1999, Time magazine placed him in the 'Time 20' list of most influential Asian people of the 20th century.”  He just celebrated his 88th birthday but is still very much young at heart.

I had originally submitted an 8-page list of questions for the interview, which I have been compiling since Tanzania.  Slowly, the pieces of the puzzle seem to be coming together, albeit in a complicated and convoluted manner.  However, when I discovered that he could only spend 15 minutes with me, I had to quickly trim my questions and choose the most important.  So here goes:

Interview with Dr. MS Swaminathan
MS Swaminathan Research Foundation, Chennai

To what degree should agriculture become mechanized and large scale?

Dr. MS Swaminathan: The story of mechanization in India is that it is taking place according to the need.  You see now labor is becoming short.  We have a program called Mahatma Gandhi National Rural Employment Guarantee Program (MNREG), which guarantees employment for 100 days.  So many of the workers who used to be in agriculture are taking advantage of this program because the payment is prompt, it’s a government program and so on.  As a result, farmers are finding it difficult to get adequate labor at the time of planting and harvesting, therefore, more and more tractors.  And also, with an increase in irrigated area, the intensity of cropping is going up.   With the whole of Punjab, wheat and rice rotation.  So the rice has to be harvested quickly or else wheat sowing becomes delayed and if it’s delayed, yield goes down.  So they use combined harvesting, Punjab started.  Then take a place like Kerala or Karnataka where workers were against mechanization in the past, but now that labor is not available, they don’t mind.  So all the crop is harvested by combined harvesting, so the tractor industry in India is growing.  The leading tractor company is here in Chennai and a very good training center to train farmers in mechanization.  And secondly, India’s population is predominantly young people, more than 50% of our population is below the age of 30.  And those young people, don’t want to do the farming in the old way with bullock cart and buffalo.  They want to have more mechanizing.   For example, look at Punjab, when young people took agriculture only when tractors and combines all came.  So the predominance of young people in agriculture necessitates relevant [mechanization].  The third very important reason for mechanization is the increasing role of women in agriculture.  Nearly 50% of our workforce is women.  For example, rice transplanting, a very tedious job, therefore transplanters are necessary since women have multiple burdens on their time: housekeeping, child rearing, and other economic activities.  Therefore, they need relevant mechanization.  So India’ agricultural future depends upon mechanization.  But I don’t mean very large horse power tractors, also what the Japanese call Kiboko – walking tractors and small for women, 10-15 horsepower.  Our mechanization will be according to our own socioeconomic circumstances based on the three reasons I gave you: labor shortages at critical times, increasing youth in agriculture, and increasing role of women in agriculture.  

Do you think organic farming can feed the world and if so, how do we “scale up” organic?

Dr. MS Swaminathan:  Organic farming, see it depends on the soil conditions.  The plant does not make a difference if the nutrient is organic or mineral fertilizer.  You may give nitrogen through urea or cow dung, animal waste.  The problem is that the majority of farmers are small farmers, holding 2 hectares (5 acres) or below or 2-3 acres.  They do not have many animals, so how will they replenish soil fertility?  You have to give back to the soil what you take out of it.  And if you are large farmer with a large number of farm animals, then it is easier.  You can use all the animal dung for the soil.  So organic manure, to produce 3 billion tons of food grains, which is what we need in the world, is not very easy.  This is why we’ve been advocating integrated nutrient supply.  Use whatever organic matter you have: animal refuse, plant refuse, compost, green manure crops (put one nitrogenous/leguminous fodder [and plow it in]).  For example, Prince Charles in the UK has a 7-year rotation with 5 years of clover and 2 years of wheat or barley to build up the soil fertility.  So essentially there are two major challenges in organic farming.  One is soil health management and the other is plant health management.  How are you going to control against pests and diseases?  How are you going to improve soil fertility?  So organic farming is not the panacea for everything because when nations were doing organic farming, India for example, until 40 years ago when fertilizer first came, it was all organic farming and we were mostly starving because productivity is so low.  If I want one ton of rice, it requires 20 kg of nitrogen.  If you want 5 tons of rice, it requires 100 k of nitrogen.  100 kg of nitrogen to give through organic manure is very difficult for a small farmer.  And you have to make it clear that the plant itself doesn’t make a distinction – organic or inorganic – it requires nutrients.

Are hybrids and GMOs necessary to feed the world’s growing population or can we relying on traditional open pollinated varieties of seeds?

Dr. MS Swaminathan: GMO is only one more technology.  Ever since Gregor Mendel announced Mendel’s Laws of Inheritance in 1865, the science of genetics has been progressing.  We have methods for doubling the chromosome, for altering patterns of chromosomes.  In 1953, Watson and Crick identified the double helix structure of the DNA model and the chemical substance of heredity.  From that time onwards, the science of molecular genetics – we have two periods 1900-1953 – Mendelian genetics and 1953 onwards is molecular genetics.  A combination of the two, Mendelian and molecular genetics, is what we use in breeding.  Normal breeding: Mendelian breeding, plus some.  For example, you must have seen upstairs, the gene from mangrove for salt water tolerance.  This is part of our program on anticipatory breeding to meet the challenge of sea level rise.  Today, the Warsaw negotiations of the climate convention have not made any progress. The richer countries do not want to cut down on emissions.  Therefore there is no way, so with higher temperature, there will be sea level rise.  And both sub-Saharan Africa and South Asian will be the worst sufferers because they have the least coping capacity against these kinds of calamities.  Therefore, I think the GM technology or the transfer of genes across sexual barriers - what is important is now that the old concept of Linnaeus, of species, was based on sexual isolation.  One species will not cross with the other.  But today, we can cross all species, we can more parasexually the genes.  It is a pretty powerful technology but it can be used effectively for certain purposes when you don’t have a gene.  For example, if I don’t have a good gene for sea water tolerance, then I can take a gene from a helophyte like mangrove.  There is now what is called marker-assisted selection, so from molecular markers, we can take a precise gene you want and transfer it.  So molecular genetics has opened up completely new opportunities.  It’s a scientific evolution.  I wouldn’t put GM versus Mendelian genetics, it’s a continuation.  We should use both.  There is no need for recombinant DNA unless it is necessary.  For example, in medicine it is being used extensively because new vaccines and so on.  And we have no concern about medical biotechnology because people want vaccines against Alzheimer’s, Parkinson’s and so on, but with the case of food crops, there is fear.  And environmental damage. 

How do you distinguish between your vision for a new “Evergreen Revolution” with the first “Green Revolution”?

Dr. MS Swaminathan: The first Green Revolution, the term was coined by William Gaud of the United States.  Suddenly there was a quantum jump in yield, from 1 ton to 4-5 tons.  It was not a small increment.  And with the shorter variety, you can apply more fertilizer and get more yield.  So he called it.  Indira Gandhi released a stamp called the wheat revolution.  Green Revolution was criticized by environmentalists saying too much harm to the soil, too much fertilizer, too much pesticide.  And there was a famous book in the United States by Rachel Carson “The Silent Spring.”  That created a lot of awareness.  She was criticizing DDT and the discoverer of DDT was given the Nobel Prize, and within ten years, Rachel Carson produced that book.  And with science, no one can ever know, so one has to do some anticipation or action-reaction.  I want one action, but reactions may be many.  So with the Green Revolution, there are 2-3 criticisms.  One is that groundwater was going down from over exploitation of aquifers.  Secondly, soil was getting salinized. Thirdly, pests were getting resistant to the pesticides.  That is well known everywhere, whether it is human disease, tuberculosis, leprosy, they become drug resistant. And that is one of the problems with medicine, agriculture, or animal husbandry, you will find there is a problem with the resistance to drugs

[[Then I added that another critique is farmer indebtedness and reliance on external inputs from the market; he replied]] Farmers have to depend on inputs.  You can’t have output without inputs.  When we were having no inputs – farmers were doing natural farming – the yields were only half a ton.  When we became independent in India, we were only 300 million people.  Today we are 1.2 billion people and today there is no famine.  There is under nutrition.  It is not like the Bengal famine, which occurred when our population was 300 million.  Therefore, you have to produce more.  Land is going out of agriculture.  Every day, land is going out, new buildings in Chennai.  The same is true in Massachusetts.  Land is a shrinking resource for agriculture. 

So I coined the term “evergreen revolution” about thirty years ago.  In fact, both the Agronomy Society of the United States and the Crop Science Society had 50th anniversary about 7-8 years ago in Salt Lake City and the theme was “From Green to Evergreen Revolution” and I was the keynote speaker.  And the book is also there.  Evergreen revolution means an increase in productivity in perpetuity without ecological harm.  You have to mainstream ecological factors in technology development and dissemination.  Today you can all it sustainable agriculture.  Green Revolution has a specific connotation: yield.  Sustainable agriculture can also be organic agriculture, but we want more yield because we have increased population and many are undernourished, therefore we need to produce more.  That can be done only by integrated pest management, integrated nutrient supply, improved post harvest technology, improved soil and water management and so on.  Now people accept this.  Even president Obama, when he addressed the parliament of India, he said we need an evergreen revolution.  Therefore, everyone recognizes that increasing yield should not be at the cost of the environment, because then we can’t have it forever.  That’s why evergreen, in perpetuity, sustainable agriculture.

Any advice for a young person like myself who is aspiring to make positive change in this area?

Dr. MS Swaminathan: My advice would be don’t go by slogans or because somebody says, “this is bad.  That is bad.”  Apply your own mind.  Ask yourself, what is the end point, what do you want to reach?  For example, we want to reach a hunger free India.  This first requires an adequate supply of food at an affordable cost, which is what our government aspires with the Food Security Act.  But the food security bill would not have been possible without the green revolution because we have so much grain because the yield of wheat and rice has been improved.  So my advice would be that young people should not just go by emotions or slogans.  You must be compassionate and have a mind of compassion and helping others, but our aim should be to ensure the first among the human requirement: adequate food and food for all, forever.   









--

I think that Dr. Swaminathan is known for his balanced approach to issues, however, he is also critiqued for giving conflicting messages (e.g. on GMOs).  Regardless, it was an honour speaking with him and I appreciate his advice.  After this quasi-celebrity encounter, I was able to spend a bit of time with some of the directors and principal scientists of the other divisions at MSSRF. 

According to their website, “MS Swaminathan Research Foundation is a non-profit research organization and was established in 1988. M S Swaminathan Research Foundation (MSSRF) has all along been developing and following a pro-nature, pro-poor, pro-women and pro-sustainable on-farm and non-farm livelihoods through appropriate ecotechnology and knowledge empowerment.

MS Swaminathan Research Foundation is carrying out research and development in six major thematic areas such as:

         Coastal Systems Research
         Biodiversity
         Biotechnology
         Ecotechnology
         Food Security
         Information, Education and Communication”

I was able to spend time with the biodiversity, ecotechnology, and biotechnology divisions.  In the biodiversity interview, I learned that they are focusing on a “4C model” approach to conservation, which pays concurrent attention to:

         Conservation
         Cultivation
         Consumption
         Commerce

One of the main points of this division is the recognition that tribal communities often hold traditional varieties, which necessitates in situ (on-site) conservation, as well as gene/seed/grain banks and participatory plant breeding (PPB) that directly involves the farmer.  MSSRF has facilitated 25 community-managed village seed banks, which also serve as storehouses for surplus grain in times of need (farmers have to return 2x as much grain as they borrow as a sort of interest).  Mill technology for local varieties can address the issues of hidden hunger.  They are also doing work on ex situ conservation and have 1,134 accessions in their seed bank with an emphasis on Prior Informed Consent (PIC), which ensures that farming communities will receive recognition if their varieties are used in any new developments.  In my interview, the principal biodiversity scientist explained that the progression of seeds is usually:

Wild type à land race à farmer variety à traditional à modern seed

I am still trying to understand the difference between various accessions including: varieties, land races, modern cultivars, traditional cultivars, wild types etc., so I will continue to ask about this and attempt to read up.  The scientist explained that the Indian state of Orissa is perhaps one of the birthplaces of rice worldwide, and this can be figured out by the vast number of varieties found in this one area (i.e. biodiversity hotspot).  Therefore, we need to support traditional/tribal communities that are working directly with wild-types.  In-situ conservation, however, has inherent limitations; for instance, these community-level programs can only be scaled up to a certain extent to remain economically viable and also because local seed is intrinsically place-based.  In-situ conservation is also important because it promotes knowledge development of the people alongside seed preservation (so this indigenous wisdom isn’t lost once local seeds are put into a far off gene bank).  The scientist has doubts if in-situ conservation will survive alongside the commercialized seed production industry, which has a bit of a choke hold around India (as well as other parts of the world).  He believes that marginal areas that are biodiversity hotspots should be excluded from markets to protect the genetic resource base, which requires strong policy (could be subsidizing people who maintain biodiversity through seed).  He doesn’t necessarily support GMOs and believes that hybrids also have their own problems.

According to the director of the eco-technology centre, “it’s about taking technology from the shelf to the grassroots level.  It’s knowledge transfer.”  I learned about their efforts to balance conserving natural resources and also utilizing them for livelihood development in a sustainable way.  They are working on eco-friendly microenterprises (e.g. food processing of oils, coconut, cashew) and allied sectors such as livestock.  For this, communities require knowledge, skills, finance, and markets.  MSSRF is operating using a SSSHG model – self-sustaining self-help group (precursor to a cooperative) and the bio-village scheme.  These bio-villages are human centered but also focus on environmental conservation (e.g. promoting vermicompost, raising on and off farm incomes, intensive integrated farming system (IIFS), integrated pest management, etc.).  The bio-village model is 20 years old and looks at natural resources and rural poverty concurrently (e.g. tapping into mushroom cultivation and floriculture for generating women’s incomes).  They have 50 villages with 3,000 women beneficiaries, the majority are landless laborers and small/marginal farmers.  The importance of technology transfer involves: on farm technologies (e.g. productivity, post-harvest, marketing etc.); off-farm/related technologies (e.g. dairy, vermicompost), which present a major challenge because they want to generate jobs and income here; and non-farm technologies (e.g. vocational skills).  The director noted that to promote youth retention in agriculture, we need ABC – attitudinal behavior change.  Farming is still largely traditional, but we are linking it to the information and communications technology sector (ICT), biotechnology, and climate-smart technology to name a few.  For instance, the MSSRF scheme of bio-industrial watersheds is a good example of linking watershed development with job creation.  The key is that unlike government schemes, these watershed projects are driven by community participation and interests, which generate work in storage, harvesting, recycling to the farms etc.).  They are going above and beyond traditional water management and scaling up, creating producer-owned companies, women’s groups etc.  MSSRF takes a “rights-based approach” and through sensitization and mobilization, it is possible to make farming lucrative.  In terms of technology and mechanization, the director noted how we need to examine village-level assets and for that, it might involve 3-4 villages coming together and utilizing tractors or SRI transplanters on a custom-hire basis, with funds recycling back into the ICT center, monitored by the producer company.

As part of the ICT initiative, MSSRF has rural knowledge centers, which help bridge the digital divide and provide location specific information to local communities (e.g. weather data, disaster management).  I was able to go to one of these village resource/rural knowledge centers when I was in Vidarbha and I saw how computers and available information were really an asset to the community.       

I wanted to meet with someone from the Food Security division, but time did not allow.  Fortunately, my interview with the biotechnology department was by far the most fruitful and useful.  Here are some notes from my interview with the director of the Biotechnology Division:

         Biotechnology is the western sense usually involves molecular biology and GMOs.  Biotechnology in India also includes molecular level science, but also a large number of techniques practiced by the people.  We are interested in how to marry traditional wisdom and modern techniques, alongside many other institutions in India.
         We are currently conducting anticipatory research for impending issues such as climate change, nutrient deficiency, salinization, sea level rise, etc.  For example, developing shielding crop varieties for salinity and drought tolerance and bioremediation in times of contamination.
         In terms of address nutrient deficiencies through biofortification, we are not allowed to experiment with Basmati rice per a restriction from the department of biotechnology, since the majority is exported abroad and the EU demands GM-free products.  But for non-basmati rice varieties, we are developing salt tolerance through genetic engineering (taking a gene from a mangrove).  In our contained trials, GM salt tolerant varieties are outperforming traditional and once this ban on large scale field experiments on transgenics is lifted, we can better test for long-term health and environmental impacts, which we will then put this info in the public domain.  Currently, we are collaborating with independent labs to test for biosafety under animal models, which have shown no adverse effects over more than three years of testing.
         Most notably, MSSRF operates and conducts research using public funds, so we do not have vested interests and are accountable first to the general population.  We must research and understand these technologies very well.  The problem is that in most developing countries, only corporations have access to GM technology, but at MSSRF, we are neither pro nor anti GM-technology but realize that it must be pursued in a safe and precautionary manner from a scientific perspective, looking at benefits and risks.   We also promote capacity building within PhD and post-graduates, so they can further independently assess this technology (rather than corporate sector).  Moreover, MSSRF has generated our own genetic material.  That is, we didn’t buy a gene from Monsanto and insert it.  We are using defensive patents to safeguard our claim on these genes and afterwards, we have every right to transfer this technology to any like-minded organization and to make the product available at a cheaper price.  Remember, we are a not for profit and our focus is abiotic stress, so we aren’t dealing with BT-cotton or Monsanto.  The problem is that early on, biotechnology entered into the hands of the private sector, who in the name of profit, often exploit people.  Remember that Golden Rice was a private endeavor pursued by a Monsanto-affiliated company.  Now GMOs have become an emotional issue and many people are not working with completely independent organizations under public funds, so of course there are vested interests.
         A huge problem is that the general public does not often understand advanced science and technology and this lack of comprehension spawns fear.  I feel that this is true with GMOs.  GMOs are a matter of sensitizing people and also not letting it become an issue of emotions or ideology.  Science needs to be ideology-free and instead, data driven.
         People are taking a stand based on flimsy arguments – they say there is no data, it’s imprecise etc. and throwing it are in the dustbin technology prematurely.  We need to research it thoroughly instead of just “beating the drum.”  Investment in biotechnology is very high, especially in the government.  Malnutrition is such a complex issue that needs to be tackled from multiple approaches.  Not saying that biofortification through GM technology is the cure-all.  But consider that we used to think that pesticides were the panacea, but now people are realizing that integrated pest management is key.  Similarly, we need to look at integrated approaches to issues such as malnutrition, which may involve GE but also diet diversification, traditional crops etc.  In biotechnology, now we have marker assisted plant breeding (plant molecular technology) in which scientists can identify exact areas where genes are located.
         Attempts to demystify technology, promote ecological and genomic literacy among children through school programs etc.
         BRAI – now it’s about biosafety regulatory authority – it should be a completely autonomous and scientific body that can independently scrutinize a technology with vested interests rather than an administrative and politicized body.  For example, in the USA, the FDA says yes or no and people generally accept the response without blinking an eye.  However, India does not have this kind of body, which is necessary.  Furthermore, BT Brinjal was recently approved in Bangladesh and has the potential to quickly enter into Indian soil, so we need a regulatory body to screen this.
         Biofuel – food versus fuel debate? 
o   MSSRF does not support transforming food stuffs into biofuel, which is why research is concentrated on crops such as jatropha, which are non-edible oil plants.  Genetic mechanisms exist to increase oil yield, so we are looking at options to promote over expression of this gene.  Moreover, jatropha prefers to grow on wasted drought affected soil (e.g. rainshadow regions, areas becoming desertified etc.), so there is no need to convert fertile soil into biofuel cropping area.  And at MSSRF, we feel that in India, feeding people is the priority.  Regarding multi-use crops such as sweet sorghum (grain, fodder, and fuel), this is a good idea in principle, but eventually private companies will get involved and push for their vested interests, which may potentially hurt the “food” component. 
         We also need to examine everything under the issue of climate change – how to best conserve fuel, water, soil etc.  We cannot just take a fragmented approach.  Everything is changing and therefore, we must use adaptive research.
         In terms of bringing youth back to the land, we need to make farming intellectually rewarding (through our programs like biotechnology, ecotechnology, ICT, which work for people) and infuse young minds with the idea of critical thinking and finding creative solutions to maximize production; most importantly, farming needs to become economically viable (intellectual stimulation may also involve teaching farmers about markets etc.)
         “Technologies not technology” – we should view this as a multi-pronged approach.  The singular phrasing gives it an ideological connotation, whereas “technologies,” plural, implies a range and combination of appropriate solutions.
         It’s all location and problem specific – cannot simply say how much traditional knowledge should be preserved as it will depend on the specific conditions: water, land, soil etc. and these must all be considered both independently and collectively at the same time.
         MSSRF can create models (e.g. how to effectively use ICT, where to sell product etc.) and these models have been adopted by Government of India and are being implemented as national programs.
         The case with India is even more difficult since the country is heavily divided based on language, caste, creed, etc. further exacerbated by the growing gap between the rich and the poor and the technological/digital divide.
         A huge part of MSSRF is empowering women.  For example the “Empowering Women Farmers Program” under the Food Security division is in direct response to the farmer suicides in Vidarbha.

In essence, I feel like my time at MSSRF was useful because of the overall balanced approach to these issues.  The biotechnology director and Dr. Swaminathan summed up very well the point that everyone has to devise their own thoughts on new developments and technologies, but it should not be based upon emotions, ideology, whims, or other people’s flimsy opinions but rather data-driven, independent science.  This especially holds true for GMO technology, which demands extensive testing, biosafety measures, application of the precautionary principle, and education/sensitization among many things.  Furthermore, again there is no magic bullet solution to the agrarian crisis – as Dr. Swaminathan said, “organic is not the panacea for everything” (and neither are GMOs).  Yes, sustainable agroecological farming may hold the answer to many of our problems, but perhaps it really does entail some integrated approaches (i.e. not ruling out external inputs, chemicals, and hybrid seeds all together) – honestly, I really don’t know.  And as stated before, I’ve spent my fair share of time with conspiracy theorists and ideology-driven people on both ends of the spectrum: comparing the March Against Monsanto protest with the corporate-laden World Agricultural forum is a stark contrast.  However, I finally feel like neutral voices are coming through.  This weekend reminds me of many conversations I had with Ginny, the Post-Graduate Fellowships Coordinator at my alma mater Hamilton College.  Frequently, Ginny would remind me to take a balanced approach, remove biases from my application, and quote – “don’t beat the drum.”  Naturally, my background and involvement with Slow Food, Real Food Challenge, and other progressive movements render me somewhat biased, but slowly I am trying to let them go.
