ACKNOWLEDGMENT



( 768-824)

“Without the horse master Bole there would be no horses of one
thousand miles. A horse which can run one thousand miles in one
stroke is not at all rare. However, a master like Bole, who can tell
which horse has such ability, is rare. As a consequence, many horses
of excellent capacity only have an ordinary life being humiliated by
ordinary man without earning a name of being a horse of one thou-
sand miles” – (Han Yu, 768-824 AD)

I thank Professor Bogardi for being a wise “master of horses” who saw my potential
(which is still not even known to myself; I feel more like the donkey of Don Quixote) and
has been “whipping”/supporting me through my entire PhD rearing process. No other
words can better describe his contribution to my personal academic development than
the story of the horse master Bole.

It is Professor Jürgen Pohl who gives the word “Doktorvater” (doctor father - the Ger-
man expression for PhD supervisor), a true meaning. Without his fatherly encourage-
ment and sometimes even psychological support, on top of all his inspiring academic
guidance, I might still be fumbling in the total darkness of confusion.

Dr. Katharina Marre as my tutor within the UNITED NATIONS UNIVERSITY Institute
for Environment and Human Security (UNU-EHS) has accompanied me throughout my
PhD journey and always been there for me whenever I needed a guiding and helping
hand. I thank her for her constant intellectual inspiration, important comments and
invaluable feedback especially through the writing-up phase.

I also wish to thank Professor Libor Jansky for helping me to find and define additional
dimensions of my work and for his useful counsel.

In addition, my thanks go to my friends Basak Baglayan Ceyhan and Patrick Schröder
who went through the “construction phase” of my PhD work, breathing in all the dust
and hearing all the noise of a construction site as well as helping me to polish the
facade of my work by proof reading. The final proof-reading was jointly accomplished
by my friends Claudia Maurer, Susanne Krings and Olivia Dun. I owe them many
thanks - and dinners (If you find any mistakes in my work, do not hesitate to contact
them).

I thank the UNITED NATIONS UNIVERSITY Institute for Environment and Human
Security for funding my PhD research as well as providing me with an excellent work-
ing environment with pleasant and helpful colleagues.

Last but not least, I owe many thanks to the following institutions in China and Ger-
many for assisting me to organise my research and providing me with valuable infor-
mation essential for my field work:
