Acknowledgement Many hearty thanks to Prof. Dr. Hans-Rudolf Bork and Prof. Dr. Joachim Schrautzer for their excellent supervisory role in my master’s thesis. Their words of encouragement when I informed them that I would travel to my home country for the fieldwork were invaluable. I appreciate immensely Dr.
Wilhelm Windhorst, the environmental management coordinator of blessed memory whose supervisory role in my projects 1 and 2 helped to improve my scientific writing skills. I am eternally grateful to my amiable wife (Tokunbo Adedara) and handsome little boy (Samuel
Adedara), who bore the pain of a temporary separation from them to enable me to pursue my dream career in a faraway land. The daily prayers of my mother (Ms. Ajibola Adedara) and her resounding words of hope cannot be ignored.
I cannot forget in a hurry, the timely funding support from Stube Nord (Diakonisches Werk Hamburg) in making the field trip a reality. Finally, I thank the leadership
of the church I attend in Kiel,
and all my friends, home and abroad as well as the ESG (the university church)
for their unflinching support, especially in the most challenging times.
