Alternative to fossil fuel

A very important facet to energy security is to look for alternative fuel options. India has joined the list of countries who have taken a commitment to move to 10 - 20% biodiesel in commercial vehicles. A lot of research is ongoing to meet this requirement by 2020, and jatropha seed oil is one of them. However, jatropha is plagued with variability in seed yields and oil content in seeds. So, an article in Deccan Chronicle recently highlighted the work in M. S. Swaminathan Research Foundation, Chennai
--------------------------------------------------------------------------------------------
An initiative by the scientists of the M S Swaminathan Research Foundation will see the country’s jatropha growers hitting gold and the possible emergence of an alternative to fossil fuel. “We are zeroing in on a variety of jatropha capable of yielding 60 times more oil seeds per plant per year. The variety of the plant which we are developing will grow in all kinds of wasteland and non-arable lands,” said Dr Rajalakshmi, principal scientist, MSSRF.
Speaking to Deccan Chronicle on the sidelines of a seminar on the bioenergy scenario in India held here on Tuesday, Dr Rajalakshmi, a biotechnologist, said the three jatropha plantations set up by MSSRF in Tamil Nadu, Orissa and Puducherry have given encouraging results. “We are in the process of scientifically testing and validating the best variety which will bring good returns to the jatropha growers and the end users,” said Dr Rajalakshmi. When crushed and processed, the jatropha seeds produce an oil that can be used in a standard diesel engine and the residue can be processed into a biomass to power electricity plants. Farmers who grew jatropha had suffered losses because of the poor yield. “They were getting hardly 100 grammes of seed per plant per year. The yield from the seeds too was meagre. Hence we launched the initiative through micro propagation and tissue culture. We succeeded in producing from a single jatropha plant many plantlets which have the same yield as that of the parent plant,” said Dr Rajalakshmi. The jatropha plants developed by the MSSRF biotechnologists will yield anything between two and six kg seeds per plant per year. “Their oil yield is more than 40 per cent than that of the traditional jatropha. Now we will isolate the seed with maximum yield and returns and distribute them to farmers,” said Dr Rajalakshmi. The bio-diesel from jatropha is unique since its emission levels would be too low compared to fossil fuels. “This will bring down the greenhouse gas emissions in the country,” she said.

Bt Brinjal and GM crops

Well, very soon, we are going to see Bt brinjal and other edible GM crops being released in India. So, we are seeing a lot of activists holding rallies, campaigns against GM. In Chennai, recently, we saw such a rally in Besant Nagar Beach. I think these activists ought to first learn a little science before trying 'to educate the public' as they claim. I do wish, sanity prevails and the public see through these publicity stunts and see logic and reason. There was an article in the Deccan Chronicle today that I wish readers of this blog to read. http://www.deccanchronicle.com/chennaichronicle/Chennai%20Chronicle/Chennai%20ChronicleDescription.asp
Let me give you all a little background.. General public ought to know that 80% of the brinjal produced by the farmer is infested with pests. To increase yields, farmers indiscriminately spray pesticides on the brinjal crop. Is this alright with public?? This is not brought to the attention of public during these publicity seeking rallies by Green Peace activists. Bt brinjal reduces the pesticide spray by 75%. Now, isn't it sensible to eat Bt brinjal if all other tests like allergenicity and toxicity studies certify that its safe for human consumption? Besides, most medicines today are being produced by GM, if they can be consumed, I don't see why its unsafe to eat GM crops....

Why Prince Charles is right - and wrong on GM crops

Well, I am reproducing here what Prince Charles had said from New Scientist as published in Aug 2008. I request you all to read his outburst (emotional) and the comments some of us left for a better understanding of GM crops.
-------------------------------------------------------------------------------------------
Many of us in the UK woke up this morning to hear Prince Charles ranting about genetically modified crops on the radio, or to see this ominous headline in The Daily Telegraph: "Earth faces GM crops catastrophe, warns Prince".
The sub-headline: "Multinational firms conducting a gigantic experiment that has gone seriously wrong'."
So far, so predictable, given the prince's well-known passion for organic farming and trenchant opposition to anything that smacks of tinkering with "realms that belong to God and God alone" (from an earlier anti-GM rant in 1998).
Yes, Charles does have another pop at genetic engineering. And yes, Charles does have a very big and justifiable pop at the multinational corporations and supermarket chains that dominate food production and distribution, especially in rich countries.
But listen to the interview and you can hear his voice rise to a pained crescendo when he says: "What we should be talking about is food security, not food production - that is what matters and that's what people [raises voice considerably] will not understand."
Food for all
How right he is. What matters most is not how much food we produce (although that is self-evidently important), but whether people everywhere can be confident of always having enough to eat, whatever the state of the world economy, whatever the climate locally and wherever people happen to live.
He is also correct in saying this objective of achieving food security for everyone can't be solved either by global multinationals or by "one form of clever genetic engineering after another".
Multinationals don't exist to feed the poor. They exist to generate profit for investors. And genetic engineering isn't a saviour technology that can feed the world, although some scientists and commentators have made the mistake of saying as much.
No. The main obstacles destroying Charles's dream of food security for all are of a political and economic nature, as underscored by a global initiative recently launched which sees poor farmers as the saviours of the planet.
Ambitious goals
The International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD), launched in April, sees poor farmers as the agents to achieve everything that Charles wants: using farming to raise the world's poor out of poverty, to even out the share of resources between rich and poor, and to reverse the decimation of forests and natural resources on which the future of the world depends.
Ambitious goals indeed. But importantly, the backers of the plan argue that the strongest tools to bring this about are economic and political, primarily through altering world trade rules to stop rich countries from providing their own farmers with subsidies that effectively exclude poor farmers from world markets. Other goals of the IAASTD sure to please Charles are to rein in the power of the multinationals through global anti-monopoly rules, and to provide buffers against drought and famine by encouraging poor countries to stockpile surpluses regionally, so spare food is always at hand locally to compensate when harvests fail.
Even building roads and railways could have a much bigger impact on food security than improving yields per se, according to nutrition and policy professor Per Pinstrup-Andersen of Cornell University in Ithaca, New York. He says that countless successful schemes to improve agricultural productivity in Sub-Saharan Africa, for example, have ultimately backfired because farmers have lacked the roads and transport links to transport and sell surplus produce in neighbouring villages and towns. Instead, they went broke because the introduced efficiencies improved surpluses for all farmers locally, flooding the market and depressing prices. Again, the message is that food security relies as much, if not more, on economics, politics and infrastructure as on agricultural productivity. So again, Charles is right.
Disaster guaranteed?
Charles is wrong, however, to reserve so much of his bile for genetic modification which, he says, will "be guaranteed to cause the biggest environmental disaster of all time". Really? Charles bases this damning prediction on examples from India and Australia.
In India, the wells started running dry long before GM cotton arrived on the scene. Most of the water was sucked out by poor farmers to irrigate new, non-GM strains of rice, sugar cane and alfalfa; the richer farmers with the most powerful pumps exacerbated the crisis by sucking shallower wells dry. Again, GM was not to blame, but the edge that the rich invariably have over the poor everywhere on the planet.
In Western Australia, where Charles reports having witnessed "huge salinisation problems", GM crops are not even grown, although a moratorium on cultivation in the state could be lifted this year. Most problems in Australia occur in the most populated areas as a result of prolonged lack of rainfall coupled with general over-consumption of water.
Damning reports
Then there is Charles's anti-GM talk of "corporate monsters" engaging in "an experiment that's gone seriously wrong, causing untold problems which become very expensive to undo". Has it really gone "seriously wrong"? The answer, it seems, depends on who you ask.
Organisations that oppose genetic engineering are never going to say anything complimentary about it. So it's little surprise that Friends of the Earth, for example, has condemned GM crops. Much of the data in anti-GM reports, though, has not been peer-reviewed, but is frequently cited without independent scrutiny.
Can seemingly independent environmental assessments of GM crops be trusted? A study of the global impact of GM recently published by Graham Brookes and Peter Barfoot of the UK consultancy PG Economics, concluded that globally in 2006, the technology reduced pesticide spraying by 286 million kilograms, decreasing the environmental impact of herbicides and pesticides by 15%.
Similarly, by reducing the amount of ploughing needed, GM technology led to reductions of greenhouse gases from soil equivalent to removing 6.56 million cars from the roads.
Cherry-picking the facts
The problem is that a dispassionate assessment of the green credentials of GM crops is almost impossible to come by at present, given the ideological baggage, mistrust and value-laden prejudice that have accompanied the technology throughout its tortured existence. It is clear that Prince Charles simply ignores or completely distrusts any data that challenges his own prejudices, or his contention that fiddling with nature is wrong.
He is to be congratulated for highlighting the importance of food security, even though the message is buried beneath a mountain of bile on the more peripheral question of whether GM crops are to blame for everything bad on this planet.
He should remember, however, that all farming - including organic farming - interferes with, and steals resources from, his beloved nature.
A key question is whether de-intensification of agriculture in rich countries simply transfers intensive production to other parts of the world, perhaps resulting in even worse environmental degradation overall. Whatever the answer, it would be interesting to know where Charles himself gets his data to support his assertions.

"I Think Auckland's rich Volcanic soil would have rather more to do with agricultural productivity. My grandmother tells the story of her grandparents arriving in Auckland from Scotland "and everything they planted grew, they though they'd found heaven on earth".Could someone please explain to my why GM is so much more dangerous than selectivel breeding? As far as I know the result - genetic changes in plants, is the same, GM is just quicker."

"Particularly in the case of GM cotton, where the botulism toxin (nasty!) has been introduced to kill boll weevils, if this were to get out, by plasmid transfer into bacteria for instance, and then to get into crops it would be a really big disaster - and guess who's stumping-up the insurance for that one...?"That's a flat out lie. Botulism toxin has never been introduced in crops.BT cotton uses a toxin which is not known to cause any harm to human(only insects have the required receptors in their stomach) from B. Thuringiensis.Coincidentally, this toxin is widely used in "organic" farming."

I fully endorse Jeremy's view on GM crops. GM crops are no different from many accepted strategies for varietal improvement, namely, plant breeding through mutation genetics, conventional breeding between selected parents. What we must ensure is that each transgenic event is carefully studied and tested before approval as is being ensured in all GM crops

State of Indian Agriculture - part 1

There is so much written on this topic, yet so little is understood by most people!! Maybe I can say, a lot is misunderstood. I feel compelled to put my thoughts down... My thoughts are largely what I have learnt from Scientists I have been inspired by and also, facts on agriculture, working in this field for well over a decade. One thing I have noticed in most people is that he /she often take a stand /position, in other words, their mind is made up and is therefore not open for discussions. So, very conveniently people opt to refer to only those aspects that support their argument and therefore give a narrow picture of events. So, here I attempt to take you all through a journey of basics in agriculture and I will use quotes from well known scientists to present a balanced picture of things as they are. I would like you all to understand the issues, concerns and challenges facing us today.

In an effort to meet our food requirements, about 11% of the world's land surface is used to produce crops, a collective area about the size of South America, and only limited potential remains for expanding the area of land under cultivation. Most of the additional gains can be made in South America and in sub-Saharan Africa, and they will be made only with the full application of all the tools available to agriculture. At the same time, about 20% of the arable land since 1950 has been lost subsequently, to salinization, desertification, urban sprawl, erosion, and other factors, so we are left with feeding 6.3 billion people today on about four-fifths of the land on which we were feeding 2.5 billion people in 1950, this being possible though a combination of selection, breeding, improved irrigation systems, soil conservation, and the judicious application of fertilizers. Modern agriculture scarcely resembles the agriculture of the 1940s, and yet it is not adequate, partly for political and social reasons, to feed all people well.

Having said this, I would like to highlight that these past 40 /50 years, particularly, post green revolution, dramatic yields were obtained in the two main staple crops of India, rice and wheat. Scientists involved in the revolution had warned all farmers to adopt sustainable agriculture, namely, rotation of crops, leaving land fallow, to name a few. But being human beings, greed took over, and the soil in India today is far from desirable. Now, allow me to please bring to your attention an important fact. All countries that uses pesticides and fertilizers are not in the same situation as India, for example, the Netherlands. Therefore, the problem lies elsewhere and not on Inorganic agriculture.

Many NGOs think switching to Organic farming is the solution. But the fact is, that nowhere has any farmer shown comparable yields between the two types of farming. Few NGOs also use 'fear psychosis' to instil fear and apprehensions amongst laymen about the technological advances in Agriculture today. All these have created doubts, insecurities, mistrust against Scientists and the Government. Fact of the matter is inspite of fertilizers and other inputs, the farmer gets only half of what is the potential yield. I will address the problems faced in the second part of the post.

Let me draw your attention to a very important quote by Dr. Peter Raven, Director at the Missouri Botanical Garden, well respected by his peers both within and outside his country. He says says and I quote, "Among all human activities, agriculture, grazing, and forestry are the most destructive of biodiversity, accounting for the exploitative use of more than half of the world's land surface." Having said that he goes on to say that however, we need to practice agriculture to feed ourselves. In other words, its all about weighing our pros and cons.
There is no perfect way or solution. All we need to do is weigh our options and take calculated risks for survival of as many species on Planet Earth as we know. In the second post on this topic, I plan to present the advances Agriculture has made since 19th century, particularly in India and the challenges we face today. I decided to write on this subject as 2 separate posts, for easy assimilation. I would love to hear your thoughts and comments.
