Jatropha Biofuel Around the World: A 13-country Tour of Development Activity

Good Article.
Jatropha has been a total failure in the world. Thinking that there will be much demand for Biodiesel from Jatropha,thousands of Government Land was taken on lease by some vested interests in India. Many people undertook cultivation of Jatropha in Madagaskar,Kenya,Tanzania etc. But they were not successful.
I had been advocating Biofuel from Agave and Opuntia besides Biogas for power production. Unfortunately in India, we are in most cases imitators but not innovators. First Box Type solar cooker was from India. But often we adopt western designs. Unless west recognizes, we don’t recognize.
I submitted a research project on Biofuel from Agave and Biogas from Opuntia to Government of India. If any industrial houses/organisations are interested in promoting this in India I have collaboration with leaders in the field from Mexico,UK.US and Australia.
Here is more important information:
Agave's lower lignin content (down to 2.4%) and higher cellulose content (62%) makes it ideal for production of Biofuel. Agave can be intercropped with Opuntia(Prickly Pear) which will be used to generate biogas for renewable electricity generation. Biogas power generators from KW size to MW size are commercially available from Germany,China,Vietnam etc. The cost of production per Kwh with Opuntia can be as low as US$ 3.00 per million BTU. On an annual basis,one hectare of agave can yield upto ten times the ethanol one hectare of sugarcane in Brazil. Agave to Ethanol's CO2 e emissions are lower than sugarcane and corn.
Water - footprint -- agave does not have any. Agave uses water,light and soil most efficiently amongst plants/trees on earth. Agave is packed with sugars, on an annual basis one hectare of agave yoelds upto 10 thousand gallons of ethanol(from its sap/juice) and 6500 gallons of cellulosic ethanol. No other plant in the World has such potential.
I have a plan: We have SPECIAL ECONOMIC ZONES (SEZ). Just like that we can start YOUTH ECONOMIC ZONES (YEZ). Wastelands can be given to youth on a lease basis(about 10 acres per youth) and 1o such youth can form a co-operative. They can cultivate fast growing multiple use plants like Agave and Opuntia. Power generation plants can be set up at local level. This way there will be decentralised power. This fits in Mahatma Gandhiji's Concept of AGRO INDUSTRIES utilising local resources and resourcefulness. Youth can be given short term training in Agricultural operations. This way we can provide employment to Youth besides bringing waste and vacant land under cultivation.
What is more, large plantations of Agave and Opuntia lead to climate Stability as both are CAM plants. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions. In a plant using full CAM, the stomata in the leaves remain shut during the day to reduce evapotranspiration, but open at night to collect carbon dioxide (CO2). The CO2 is stored as the four-carbon acid malate, and then used during photosynthesis during the day. The pre-collected CO2 is concentrated around the enzyme RuBisCO, increasing photosynthetic efficiency.

Here is an interesting analysis on Jatropha in India.
“The Indian experience The National, a newspaper published in Abu Dhabi in its May 11, 2009 issue, published an article titled; ‘Jatropha seeds yield little hope for India’s oil dream.’ The article referred to a project that was embarked upon by Professor R. R. Shah in 2005, when he sent a team to Navsari Agricultural University’s most parched and desolate strip of land, a farm in the Vyasa district of India’s northern state of Gujarat. The team was instructed to set up a model farm for jatropha, the hardy shrub with oil-rich seeds that were then emerging as one of the most promising alternatives to crude oil. At the time, jatropha’s promise seemed boundless. A. P. J. Abdul Kalam, the president of the University, even used his presidential address that year to extol the virtues of jatropha. “Jatropha can survive in the most arid wastelands”, the story went. And so vast barren swathes of India could be put to productive use. It is inedible so it would not cause a backlash by competing with food crops, it said. The government, according to the publication announced a scheme to plant 13 million hectares, enough to generate nearly 500,000 barrels of jatropha oil per day. But as Prof Shah’s project in Vyasa nears its end this month, the dean of agribusiness at Navsari is sceptical. “There is no yield,” he says. “The literature said that with dry land, after four years’ growth, you can get a yield of 1kg per plant. For us, it is hardly 200g per plant.” The consensus of the team of experts after evaluating India’s jatropa projects from 22 agribusiness colleges across the country was that, indeed, jatropha would grow on wasteland, but would give no appreciable yield. “This is not a wasteland crop. It needs fertiliser, water and good management. Yes, it grows on wasteland, but it doesn’t give you any yield,” the publication quotes Dr Suman Jha a researcher on Prof. Shah’s team as saying. If this observation is anything to go by, then the persistent argument that jatropha could grow on unproductive agriculture land should be looked at again. This argument also challenges the assertion that investors are not a threat to smallholder farmers,whose productive agriculture land stands to be annexed by powerful multinationals for the cultivation of biofuel crops. Non of the projects cited in The National story, including D1 Oils’, a London-listed biofuels company, which has planted about 257,000 hectares of jatropha, mainly in India was successful. The company moved far too early. The report indicated that D1 is also having some nasty surprises on yield. It said in 2006 that it aimed to produce 2.7 tonnes of oil per hectare from areas planted with its new E1 variety, and 1.7 tonnes of oil from normal seed. That is equivalent to about 8 tonnes and 5 tonnes of seed per hectare respectively, or 3.5kg and 2kg a plant. According to the report, Pradip Bhar, who runs the company’s D1 Williamson Magor Bio Fuel joint venture in India’s north east, admits he has yet to achieve a fraction of that. “Hitting 500g is the challenge,” he says. “Mortality is quite high. But if we can reach 500g in two years’ time, after that the bush will continue to grow. Our expectation is that after the fourth year we will hit 1kg. The 1.5kg mark we haven’t touched as yet.” Those are the results from the fertile state of Assam, According to the report. The yields in other, dryer states such as Jharkand and Orissa, he says, are much worse. Mr Bhar intends to hold the area under cultivation steady at about 132,000 hectares this year. As his plantations account for more than half of D1 Oils’ Jatropha crop, the company’s goal of planting 1 million hectares by 2011 looks like a tough one. He is concentrating instead on ensuring his small contract farmers continue tending it for the two or three years needed before it becomes profitable. This challenge is one of the reasons why Prof Shah doubts the 500,000 hectares of jatropha the Indian government estimates has been planted so far. Only last month, he unsettled an annual meeting of the universities researching jatropha and India’s National Oilseeds and Vegetable Oil Development Board by reporting that only 5,000 hectares was actually under plantation in Gujarat, half the official estimate, the report added. The Indian experience can provide sufficient evidence for a careful, and thorough, cost-benefit analysis of Ghana’s jatropha dream, before the bubble most probably bursts. From May 27 to 28, an international conference on jatropha in Ghana would be considering the benefits of the crop to the global economy. Hopefully, the conference would not hype the benefits of jatropha and neglect the possible pitfalls. An objective consideration of all the possibilities, including that of possible failure, as the Indian experience has shown so as to minimize any collateral damage in the long term is necessary for the move forward. The companies investing in jatropha and other non-food crops for the production of biofuels including the ones from India, have lots of lessons to learn from India’s example, so as not to repeat the mistake

Developing countries like ours which have millions of hectares of waste lands can transform rural economy by going in for Agave and Opuntia plantations on a massive scale. As one Economist put it, IT IS NOT THE LACK OF RESOURCES BUT RESOURCEFULNESS THAT EXPLAINS WHY PEOPLE PERISH IN THE MIDST OF PLENTY.

India Makes Plans To Spur More Renewable Energy Development

Glad to know that India plans to have massive deployment of Renewables.

Here is a BLUE Print for Renewables Usage in India:
1. Promote Offshore Wind Farms.
2. Promote small wind generators as decentralised systems
3. Roof Top PV Solar
4. Creating Renewable Energy Fund. Investment by Income Tax Payers to be exempted
under Section 80C.
5. Wind Farm Co-operatives on the lines of those in Germany,Denmark etc.
6. Solar Co-operatives on the lines of those in US.
7. Energy Conservation by replacing most of the inefficient 2.6 million irrigation
electric pump sets(About 30% power can be saved). Agriculture consumes much power
next only to Industry
8. Reading lights with reliable and quality dual powered(Solar/Electricity/USB) to save
enormous energy.
9. Biofuel/Biogas for power generation and cooking from Agave/opuntia care-free
growth,regenerative and CAM plants. In China Biogas for cooking is supplied trough pipes.
In the vast vacant land in India Agave and Opuntia can be grown and power generation
established as decentralised locally.
10. Simple Box Type Solar Cooker with frying facility( 3D approach,Design,Demonstrate and
11.Cost effective vertical and cylindrical,mobile solar water heater design.
12. Low head Micro hydro device to generate power from the head of falling water from the
delivery pipe of Electric/diesel pumpsets.
13. KW size Biogas power/cooking plant for villages.
14. Simple solar drier
15. Growing CAM Plants in Waste and Vacant lands which act as Carbon Sink.

In carrying out the above innovative projects services of Experts in the field,NGOs etc. can be utilised by the Government.

Preventing Bird Deaths at Solar Power Plants, Part 2

EXcellent. The simplest way to scare birds is to create bird idols with a casette inside resembling cries of dirrefet birds with timer. It can be switched off in the nights. This is cheapest way than the' radar, mobility, and digital recordings of distress calls — and also other alarming noises like the sound of helicopters — is able to drive birds away along a specific trajectory over long distances.'. Perhaps the investment is so high that one person can be employed from 9 am to 5 pm with a mike to set cries of birds.
There is:
Bird Scare Flash Tape. Used in agricultural industry to control and scare birds and pigeons by making use of holographic images, these tapes are appraised among clients as it moves in the wind with changing colors and patterns.. Some features of this Bird Scare Flash Tape are as follows:
• Lightweight
• Simple to use
• Durable

Other details:

Irri-tape pigeon scarer is effective, according to the distributor, because it flashes as it moves in the wind with constantly changing colours and patterns. The flashing ripple effect unsettles the target species and is perceived as a danger signal. Viewed from a distance, Irri-tape has a reptilian sheen and as a result may beperceived as a predator by other birds, thereby scaring them. The perceived movement of Irri-tape, courtesy of the holographic images, may even be seen by the target species as a rival for food or territory.
Irri-tape not only scares pest species of birds visually but also by making a metallic rattling sound when caught in the wind. The combination of audio and visual scarers in one product makes Irri-tape pigeon scarer an interesting bird control option.


There is a proverb used for BUTTERING PEOPLE(CROW CATCHING), but is it so difficult to scare Crows?
Local methods used by Farmers to scare birds in Agricultural fields and while sowing Groundnut(Peanut) need to be studied by Solar PV project promoters as well as wind energy promoters.
