ACKNOWLEDGM ENT
Several persons have been actively involved in allowing this thesis to be concluded. First
of all, I would like to thank my first supervisor, Prof. Dr.-Ing. Gerhard Lappus for
accepting my topic and enable me to work in this particular field. I would also like to
acknowledge my second supervisor, Dr. Jörg Becker for his time and consideration
giving me useful hints and thought-provoking ideas. He provided me with the most
valuable guidance and critique for the completion of this thesis.
My friend Andrea Tönjes deserves credit as well because of her support teaching me how
to put together the pieces of my (sometimes) disjointed thoughts. Additionally, I would
like to thank PD Dr. Oliver Dilly from the Chair of Soil Protection and Recultivation for
his important inputs to this thesis.
Thanks also to MSc. Piotr Jaworski for the time he invested providing me with scientific
support.
I would also like to thank my "Cottbus family" for their encouragement for developing
this topic (I will not forget that late night kitchen-debate that shaped the beginning of this
wonderful project - Thanks Lauro!). Juan Pi Gutierrez deserves a special mention. He
managed to be surer of my ability than myself from the beginning of this venture.
Moreover, I would like to give my appreciation to Ivan Zaleta, with who I am immensely
indebted for his inspiration and support, professionally and personally.
Naturally, I would also like to thank my family, which makes everything I do, possible.
Finally, I would like to express my gratitude to the Programme Alßan. Without its support
it would not have been feasible for me to carry out and to complete this project.

FOREWORD
In the light of availability concerns and environmental implications of fossil fuels,
attached with the remarkable rise in the price of oil during the past several years; biofuels
are getting a significant increase in interest worldwide from governments, private
investors, farmers and the public in general.
Nevertheless, the use of cropland for biofuels had become a very controversial topic.
On one hand, promoters state that biofuels represent opportunities to increase the energy
security and to generate environmental and social benefits (through greenhouse gases
emissions reductions and poverty alleviation through rural development respectively).
On the other hand, topics such as the effects on food prices and availability, soil fertility
and erosion, competition for scarce land and water resources and biodiversity loss are
also widely discussed as important concerns related to further development of bioenergy.
Notwithstanding this, several developing countries around the world are turning into the
biofuels direction to satisfy the demand of developed countries while contributing to their
economical growth and/or diversifying their current options of energetic arrangements.
For Latin America and the Caribbean (LAC), a geographical area with privileged natural
resources; home-grown energy crops emerge as an appealing possibility, especially given
the example of Brazil, a historical leader in ethanol production.
After assessing some core elements of the biofuel′s debate, the evidence seems to
suggest that biofuels may represent a valuable source of renewable energy. Nonetheless,
in order to represent a promise to the LAC region, local governments will be required to
firmly normalize land use and agricultural activities, while cautiously shaping public
policies. Whether the biofuels′ boom will represent an opportunity or a risk for the LAC
region would depend on how each country regulate agricultural and manufacturing
practices, including how many small farmers and workers from rural areas would benefit
from the industry.

1. I NTRODUCTION
1.1 M OTIVATION
Today, the modern global community is greatly dependent on non-renewable resources,
especially, on fossil fuels. Growth of their employment for long periods of time had taken
place as if there were not limitations in terms of availability or environmental implications.
Nevertheless, fossil fuels (especially oil) are distressed by geopolitical complexities that
augment price instability, affecting the economy in global terms.
In the light of the remarkable rise in the price of oil during the past several years and
considering that they can replace petroleum fuels in today′s vehicles; biofuels are getting a
significant increase in interest from governments, private investors, farmers and the public
in general worldwide. Therefore, it should not be a surprise that biomass is considered by
some players as a feasible alternative to comply with the current energy requirements.
Promoters state that biofuels represent opportunities to increase the energy security and
to generate environmental and social benefits (through greenhouse gases emissions
reductions and poverty alleviation through rural development respectively).
On the other hand, topics such as the effects on soil fertility and erosion, competition
for scarce land and water resources, and biodiversity loss are also widely discussed as
important concerns related to further development of bioenergy.
Maybe the most controversial implication of biofuels expansion is the significance of
agricultural resources for food security worldwide. This aspect has been intensively
discussed in the scientific and political sphere.
This last point is exactly from where the main motivation of this research came from.
It came from the concern about the possibility that large scale political decisions in this
matter would be justified notwithstanding social and environmental costs. This unease
might have been aggravated by the fact of coming from a net food importing country.
