Title

The title of the thesis has not yet been finalized but a working title could be

‘Cultivation of biofuels and its effect on food security’ A look at the cultivation of Jatropha curcas L. in Ghana.

Introduction

There is no doubt about the fact that the modern world is hungry and thirsty

for an alternative source of energy to petroleum fuels. Three major reasons

may account for this hunger. Firstly, the world’s oil reserves are gradually

dwindling at a very fast rate and demand for oil is sharply outstripping

supply, thereby dramatically pushing up oil prices (Pahl, 2005). Secondly, it

is estimated that about two-thirds of the world’s oil reserves are located in

the middle east, a region considered as the most unstable part of the world.

Therefore the region cannot be effectively relied upon by the rest of the

world for an uninterrupted supply of oil. Furthermore, the production of

fossil fuel releases large amounts of greenhouse gases into the atmosphere

leading to global warming with its untold consequences.

Biofuel is one of the alternative sources of energy that has generated a lot of

enthusiasm and new possibilities in recent times. Biofuels are liquid or

gaseous fuels that are derived from the biomass of energy crops (Pahl,

2005). Biofuels include ethanol (grain alcohol), methanol (wood alcohol),

methane, hydrogen and biodiesel. However, ethanol and biodiesel are the

two fuels that have generated much interest and are in commercial

production in recent years. Ethanol is derived from the conversion of

biomass carbohydrate into sugar and the subsequent fermentation of the

sugar. Biodiesel, on the other hand, is produced through the

transesterification of organically derived oils or fats (IPC, 2006). ‘Ethanol

can be used as a fuel oxygenate and, in compatible engines, as a substitute

for gasoline (petrol). Biodiesel can replace petroleum diesel, but it is

typically mixed for commercial use in 2/98, 5/95 or 20/80

biodiesel/petroleum diesel blends’ (IPC, 2006). The commonly used Biofuel

crops include food crops such as corn, sugarcane, soybeans, sunflower and

rapeseed. The common non-food crops that are planted for their energy

conversion include switch grass, miscanthus, castor and jatropha.

Various countries have made significant strides in the production of biofuels

in recent years. These include Brazil and the United States which are

regarded as the leading producers of bioethanol from sugarcane and corn

respectively. Production of biofuel from soybeans is also increasing in the

United States. Malaysia and Indonesia are noted for the production of

biodiesel from palm oil while Germany has produced quite a significant

amount of fuel from rapeseed. In 2005, Germany produced over half of the

world’s biodiesel from rapeseed (IPC, 2006). The use of jatropha as a fuel

stock has actually taken root in India and many African countries such as

Ethiopia, Ghana, Kenya, Malawi, Nigeria, Senegal, South Africa and

Zimbabwe in recent years. For example, the government of India (GOI) has

launched a national mission on biofuels with the aim of achieving a target of

20% blending of biodiesel by 2012 and this is expected to be derived from

jatropha oil seeds to be planted on about 13.4 million hectares of marginal

land (GOI, 2003 as cited in Rajagopal, 2008).

Literature review

Jatropha curcas L. (physic nut) is a drought resistant perennial crop belonging to the family Euphorbiaceae. It is a small tree or shrub having a smooth grey bark, which exudes whitish, watery, latex when cut. The plant normally grows to a height of between three to five metres. However, under favourable growing conditions, it can attain a height of up to eight or ten metres. It is easy to establish and grows well in poor or marginal soils. It is a

tough plant, grows relatively quickly and easy to establish and propagate. Jatropha grows in many parts of Africa including Ghana.

The true origin of the plant is still not clear, however, it is believed to have originated from Mexico and Central America (Jatropha, Africa). It now grows in most parts of the world especially the tropics and subtropics.Jatropha is a drought resistant crop which is adapted to arid and semi-arid conditions. It requires an annual rainfall of 300-1000 mm to thrive, with an average of 600 mm, although it can survive three years of drought by dropping its leaves (Reuk). It usually grows at annual temperatures of about 20-28 degrees Celsius, although it can tolerate a light frost (Jatropha, Africa). It grows on well drained soils with good aeration but is also adapted to poor soils with low nutrient content. It has low water requirement and does not require irrigation. The plant sheds its leaves during the dry season and winter months in order to reduce transpiration and conserve moisture. It is cultivated at a planting distance of 2 metre intervals and about 2500 plants can be cultivated per hectare.

Jatropha is a fast growing plant which begins to bear fruits in the second year and continues for the next forty to fifty years. Optimal yields are obtained from the sixth year. Flowering of the plant occurs during the wet season and it takes about three months for the fruits to reach maturity. Two flowering seasons are usually observed during the year. However, flowering can occur throughout the year with good all year round soil moisture and sufficiently high temperatures. The annual seed yield ranges from 0.5 to 12 tonnes per hectare. Jatropha produces seeds with an oil content of about 37 to 40%. It produces over 2000 barrels of oil per square mile per year (Reuk). One hectare of jatropha yields about 7 tonnes of seeds per year which yields about 2.2 - 2.7 tonnes of oil. The oil pressed from 4 kg of seeds is needed to make 1 litre of biodiesel (Reuk).

Jatropha is regarded by many as the ‘wonder crop’ for biofuel production due to its numerous advantages over conventional petroleum diesel.

A lot of concerns have been expressed about future food security due to the potential competition of biofuel crops with other food crops for land. Using good quality arable farmland for biofuel crop production will inevitably lead to food insecurity and high food prices beyond the reach of the world’s poor people. However, jatropha can be grown on marginal land or poor soils with low nutrient content. Research has shown that jatropha increases the fertility

of the land on which it is grown, thus making it possible to be used for the production of food crops in subsequent years (Reuk).Jatropha has a very high oil yield. Over 200 barrels of oil yield can be achieved per square mile per year as compared to rice and corn which yield almost 1000 barrels and under 200 barrels per square mile per year respectively (Reuk). Jatropha oil does not contain sulphur. Therefore, it is a source of clean, low emission fuel. Unlike the common biofuel crops such as corn and sugarcane, the cultivation of jatropha does not require irrigation nor suffer during periods of drought, thus making it more suitable to cultivate by poor farmers in developing countries who almost entirely depend on rain fed agriculture.Jatropha trees shed their leaves during the dry season in order to reduce transpiration loss and to conserve moisture. The leaves form mulch around the base of the plant and also prevent soil erosion. Organic matter from the decomposition of shed leaves improves the fertility of the soil.It is possible to intercrop jatropha with many cash crops such as coffee, sugar, fruits and vegetables. Jatropha can be used as a hedge or a border plant to offer protection against livestock. The pressed cake from the processing of jatropha is a good source of organic matter. The detoxified oil pressed cake of jatropha can be used as an animal feed whilst a second by-product called bio-glycerol can also be used for soap-making and pharmaceuticals.A special characteristic of jatropha lies in its ability to absorb high levels of carbon from the atmosphere, thus helping to reduce carbon dioxide concentration in the atmosphere and hence pollution. Jatropha cultivation can also earn carbon credits.

Description of study area

The research will take place in Sogakope in the Volta region of Ghana, about 110 km from Tema, the largest seaport in Ghana, where a Norwegian biofuel company, Biofuel As, has acquired a 950 hectare farmland for jatropha cultivation. Out of the 950 hectares, about 200 hectares have already been planted with jatropha over the past 15 months.

Sogakope is the capital town of the South Tongu district of the Volta region. The district covers an area of 448 km2 with a population of 64,852

(2002 census, http://en.wikipedia.org/wiki/Sogakope). The main economic activities of the people are farming, fishing, animal rearing, petty commerce and tourism. The district has a tropical climate with moderate temperatures of about 21-30 degrees Celsius (70-90 degrees Fahrenheit) for most part of the year. The average annual rainfall figure is between 1168 mm and 2103 mm. There are two rainy seasons within the year, from March to July and from mid-August to October.Politically, the district is headed by the District Chief Executive who is responsible for the day-to-day executive and administrative functions of the district assembly and is the chief representative of the central government.

I have chosen Sogakope as my study area because it is an area of large scale jatropha cultivation for Biofuel, covering about 950 hectares of land area. Moreover, majority of the inhabitants are farmers. Therefore, it is an ideal place to conduct a research on yield analysis of jatropha.

Methodology

The nature of my research involves yield analysis, crop establishment, method of cultivation and the development of a database for jatropha cultivation at Sogakope, Ghana. These assessments require a quantitative approach. According to Bryman (2004), quantitative research is a research strategy that entails the collection of numerical data. I will employ the survey design and the face to face type of structured interview for my data collection. I will then use SPSS to analyse the data set that has been gathered. I expect to acquire this data from Biofuel As and from the interview conducted on farmers and to compare and contrast the two data sets in order to look out for any discrepancies. Where necessary, I will conduct field experiments to obtain the needed data. On the issue of establishing good relationship between the company and the community, I will employ qualitative interviews to find out the existing relationship between the company and the community and how this relationship can be improved. Bryman (2004) defines qualitative research as a type of research that emphasizes words rather than quantification and has a ‘preference for an emphasis on the ways in which individuals interpret their social world’. Here, I will employ the semi-structured type of qualitative

interview for my data collection. I will make use of interview guide or key questions. My main informants will be farmers and Biofuel As.

Ethical considerations

Ethical issues in social research can be identified in four main areas namely; harm to participants, lack of informed consent, invasion of privacy and deception (Diener and Crandall, 1978, as cited in Bryman, 2004).

In the course of my research, I will try as much as possible to make clear to my informants about who I am, where I come from and the purpose of my research. I will make sure that all informants willingly give out information without any form of coercion or negative inducement.

Finally, I will ensure that every information obtained from my informants is kept in confidentiality and their consent sought before making any publication.
