ACKNOWLEDGEMENTS

During my PhD study at department of Cartography, GIS and Remote Sensing of
Geographical Institute at Georg-August-Universität Göttingen, I received support
from many colleagues and friends. This thesis is the most important work of my PhD
research which would not have been finished without help and cooperation of many
individuals and organizations. I would like to express here my sincere thanks to them
all.
First of all, I would like to express my deepest appreciation to my supervisor,
Professor. Dr. Martin Kappas, who guided me in my research work by providing
valuable advice. His feedbacks have been extremely helpful in improving this thesis.
I would also like to express my sincere gratitude to Dr. Stefan Erasmi for discussions,
suggestions and occasionally technical support at various stages of this study. I would
like to thank Msc. Nguyen Xuan Quan and Mr. Phan Van Tien for working together
with me to develop the Decision Support System program.
My thanks are also extended to Prof. Dr. Dao Chau Thu, Prof. Dr. Ho Tu Bao and
Prof. Dr. Nguyen Hai Thanh, Dr. Daniel Kathe, Dr. Nguyen Trung Thanh for their
comments.
I would like to thank Ms. Bui Thi Thanh Hoa, Ms. Nguyen Thi Hoai Thu, and Ms.
Catrin Collatschny for helping me with proof reading of the thesis manuscript.
I am also indebted to staff members in Tam Nong district, Committee, Department of
Resource and Environment, Phu Tho Province and Hanoi University of Agriculture
for providing data, helping me collect field data for relevant maps and providing soil
property detailed.
I would like to thank the Vietnamese Government, specifically the Ministry of
Education and Training, for giving financial support to my studies via Project No.322
- the Vietnamese Overseas Scholarship Program and the German Academic Exchange
Service (DAAD) for supporting my studies in Germany
Finally, I would like to express my deepest gratitude to my family, especially to my
wife and son for giving great support, love and inspiration during my doctoral study.
