Alternative fuels, Jatropha cultivation in Mali & India

Alternative Agro-fuels: Jatropha cultivation in Mali & India

Hamza Hasan
Food First

Agro-fuels first entered the development discourse in the aftermath of the second oil crisis in 1980. Seen as a renewable energy source, many policy makers around the world supported increased production of Agro-fuels as a substitute for increasingly expensive imported oil. In the last few years, with increasing political instability in the Middle East, and rising oil prices, Agro-fuels are once again being promoted aggressively. Proponents of corn-based ethanol argue that in addition to reducing American dependence on imported crude oil, increased ethanol production will benefit rural economies and provide a solution to the farm crisis. However, as the increasing numbers of corporate owned ethanol plants testify; instead of increased rural development, the major beneficiaries of the ethanol boom are large agro-industrial corporations such as ADM. Since corn based ethanol production is unlikely to serve as an efficient medium of development, it is necessary to study alternative agro-fuels, and in particular, examine agro-fuels that may be beneficial to developing countries. The Jatropha crop is one such alternative agro-fuel. Jatropha production, as the case studies of Mali and India will illustrate, is labor intensive, does not compete with food crops for land, and most importantly, provides an engine for growth in rural economies.
With food prices reaching new highs, it is not only important to re-evaluate the food security implications of agro-fuel production but it is imperative to find an alternative to corn-based agro-fuels that threaten existing food supplies. Fuel oil extracted from the Jatropha plant, an inedible shrub with the capacity to grow in the world’s semi-arid regions, may provide an environmentally sustainable agro-fuel option that does not compromise the world’s existing food system.
Jatropha oil is extracted from the Jatropha Curcas plant. Originally known as a plant used for traditional medicine; the plant also produces small seeds which contain more than 30 % content of non-edible oil. Jatropha’s usefulness as an energy crop stems from its hardy physical characteristics. According to the World Agroforestry Center, the Jatropha plant is drought resistant, can grow in a low quality arid soil, and requires minimum rainfall. In addition to its suitability as a side plant for food crops, the Jatropha plant also repels insects, requires little care, and can grow in tough arid climates, preventing soil erosion and making it an ideal fence to protect other plants. (1)
One of the best examples of a sustainable usage of Jatropha is found in the West African country of Mali. The Jatropha program in Mali began in 1993 with German Technical Assistance. The program not only aimed to use Jatropha oil as a fuel but also use Jatropha cultivation as a springboard for energizing rural economies. (2) The small village of Simiji has recently been transformed by Jatropha production. By crushing the seeds of the Jatropha plant and extracting the oil, village residents have found a renewable power source that does not conflict with the local food supply. Oil from the Jatropha plant, long considered useless, now powers a small generator. Simiji now has enough power to run 40 streetlights and give 60 families power at night. The usage of Jatropha in Simiji is not an isolated case of success in Mali. It is one of 700 communities that have installed a generator; which can run on plant oil, part of a larger state run project to electrify the country’s 12000 villages through a renewable energy source that does not harm the local food supply. Aboubacar Samake, head of the Jatropha program at the government funded National Center for Solar and Renewable energy, noted that a number of foreign companies had shown an interest in developing a Jatropha industry in Mali. Encouragingly for the local villages, Samake said that the foreign companies had been told that no agro-fuels would be exported until Mali’s domestic needs were met. (3)
Another country that is also investing heavily in Jatropha production is India. Similar to Mali, the Indian Jatropha grows in the wild, does not require large-scale irrigation projects and can be harvested within two years of planting. In contrast to Mali, India’s investment in Jatropha follows a more conventional path of development in alternative energy resources. While the Jatropha plant in India is the same as the one in Mali, the goals of the Jatropha program in India are somewhat different. In Mali, the Jatropha plant was used to develop a renewable power supply for each individual village, however, in India, Jatropha planting is primarily aimed at reducing oil imports and achieving energy independence. Jatropha cultivation in India also received a strong boost after the President of India Abdul Kalam announced he was a supporter of the project. (4) Moreover, as the cultivation and harvesting of Jatropha is labor intensive, increased Jatropha cultivation is seen as a way of providing employment to the many of India’s rural poor, thus rejuvenating India’s rural economy. Moreover, and perhaps most importantly for India’s food supply, since Jatropha grows primarily in the semi arid regions where food crops would not be able to survive without expensive irrigation projects, Jatropha cultivation will not compete with existing food crops.(5) As a result, fuel from Jatropha plants will not alter the existing Indian food system.
A fork in the road
As noted earlier, although both Mali and India are investing in Jatropha as an alternative energy fuel, their respective Jatropha strategies are vastly different. Recently, Mali’s President Amadou Toumani Touré, hosted the World Forum for Food Sovereignty, and publicly declared the goal of achieving food security as one of the major policies of his government. (6) Thus, the Malian Jatropha project’s emphasis on the local sustainable usage of Jatropha as an agro-fuel comes as no surprise. In fact, it is part of a broader drive towards food sovereignty in the entire country.
In India, however, we note the slowly permeating influence of biotech companies and large agro-industrial corporations into the Jatropha industry. In 2004, India’s largest state, Uttar Pradesh, announced the creation of a Jatropha Genetic Enhancement Research Centre. This research facility would experiment with genetically modified varieties of the Jatropha Curcas plant while also helping farmers interested in commercially planting Jatropha.(7) The growing influence of large corporations is seen in the entry of Daimler Chrysler into the Indian Jatropha production market. The German automobile giant, working together with an Indian research organization CSMCRI, have attempted to adapt Jatropha oil for usage in commercially produced car engines. In fact, as part of a public relations campaign to raise awareness about Jatropha oil’s possible usage as an automobile fuel, a specially modified Daimler Chrysler C220 sedan toured India in April and May 2004, visiting 11 major cities.(8)
Thus, before endorsing Jatropha as an alternative agro-fuel, we must strike a note of caution. Mali’s usage of Jatropha purely on a grassroots level is commendable, and its decision to disallow foreign companies from commercializing Malian Jatropha production can serve as an example for other developing countries. The Indian government’s policy towards Jatropha, however, is a cause for concern. The government’s flirtation with corporate behemoths such as Daimler Chrysler and indulgence of biotechnology firms could end Jatropha’s utility to the Indian farmer, and will only serve to further enrich the pockets of large agro-industrial and energy corporations. At this stage, the Jatropha bandwagon is presented with a fork in the road. Whether to use Jatropha as part of a broader sustainable strategy for development, as is occurring in Mali, or to extend, as India seems to be doing, the tried (and largely unsuccessful) strategy of industrial agriculture into the field of Jatropha production. The corporate takeover of the Jatropha production – as it seems to be occurring in India – will undoubtedly lead to Jatropha becoming just another tightly controlled plantation based agro-fuel. In order for Jatropha to truly serve as a vehicle for rural development, the Malian model of small-scale sustainable production must become the dominant discourse in the use of Jatropha as an alternative agro-fuel.

Jatropha Curcas


Jatropha Curcas

Jatropha Curcas  

The Jatropha Curcas plant is a poisonous shrub that is being hailed as the next alternative fuel source.  The jatropha curcas is ideal for the town of Mole Saint-Nicholas, as it can thrive in the worst agricultural conditions.  The plant can essentially grow in a wasteland, and can even flourish between rock crevices.  With a germination period of only 9 days, the plant needs only 10 inches of rain a year (most important during the first two years), and can survive up to three years of droughts.  The plant produces seeds after its first year, and can survive up to fifty years.

Once seeds are produced, they are crushed.  The crushed seeds yield up to 40% oil per seed.  The oil can go right into a standard diesel car engine.  The residue of the plant can be converted into a biomass to power electricity plants.  In addition, the leaves dropped by the plant act as a fertilizer and enrich the soil, as well as prevent erosion.  Since the Jatropha curcas absorbs carbon dioxide, using the biodiesel fuel can reduce carbon emissions up to 80%.

British Helius Energy chief executive Lex Worrall says: “Every hectare can produce 2.7 tonnes of oil and about 4 tonnes of biomass. Every 8,000 hectares of the plant can run a 1.5 megawatt station, enough to power 2,500 homes.”  Although ingesting three uncultivated seeds can kill a human, the jatropha curcas is a promising alternative fuel source.

CDGK to grow Jatropha plants

 CDGK to grow Jatropha plants


KARACHI - The Forest Department, in collaboration with Pakistan Army, has successfully cultivated Jatropha plants used to obtain biodiesel fuel in various developing countries, sources revealed to The Nation on Monday.
Jatropha is cultivated in Mexico and Brazil and its oil is used produce bio-diesel to combat the increasing prices of petroleum.
The forest department initiated the cultivation on experimental basis four months ago in Malir Cantt. The seeds of Jatropha plants were given by Pakistan State Oil (PSO) to forest department of CDGK, sources said.
The importance of Jatropha plant increased during 2007-08 when high prices of petroleum were increased manifold and developing countries started its cultivation to maintain the pace of their economic progress. Its cultivation is successful in arid areas and Sindh province is an ideal place for this purpose. The idea of cultivating Jatropha in Karachi was conceived by the DO Forests, who had approached PSO to get seeds of the plant, sources said.
Four months ago, the seeds of Jatropha were sowed on the land of Malir Cantt, and now around 3,000 plants making fast growth.
Sources added that due to the success of Jatropha plants on experimental basis, its fame spread among the farmers community.
The agriculturalists are interested to start its cultivation in their areas and many among them have approached forest department to get seeds of the plant and other details.
At present, the forest department has more than 10,000 saplings of Jatropha at its nurseries, which would be provided to the farmers and planted in other parts of the province.
The sources said that credit of achievement goes to the forest department and Pakistan Army, who took a bold decision at the right time without spending any funds.
Corps Commander Karachi has also visited the cultivated land in Malir Cantt and appreciated successful cultivation of Jatropha plant on Pakistani soil.
Currently the oil from Jatropha curcas seeds is used as bio-diesel in Philippines and Brazil, where it grows naturally. Likewise, Jatropha oil is being promoted as an easily grown bio-fuel crop in hundreds of projects in India and other developing countries, sources said.
Jatropha oil is significantly cheaper than crude oil.

Jatropha curcas, Jatropha Tree

Jatropha curcas  a species of flowering plant in the spurge family, Euphorbiaceae, that is native to the American tropics, most likely Mexico and Central America.It is cultivated in tropical and subtropical regions around the world, becoming naturalized in some areas. The specific epithet, "curcas", was first used by Portuguese doctor Garcia de Orta more than 400 years ago and is of uncertain origin. Common names include Barbados Nut, Purging Nut, Physic Nut, or JCL (abbreviation of Jatropha curcas Linnaeus).
J. curcas is a poisonous, semi-evergreen shrub or small tree, reaching a height of 6 m (20 ft). It is resistant to a high degree of aridity, allowing it to be grown in deserts.
The seeds contain 27-40% (average: 34.4% ) that can be processed to produce a high-quality biodiesel fuel, usable in a standard diesel engine. The seeds are also a source of the highly poisonous toxalbumin curcin.
