AcknowledgmentThough I was the one to take all steps in preparing, conducting and finalizing my PhD research, I did not travel alone. Many other people travelled with me, contributing to the success of my learning process and making my tough journey also a pleasant one. They invested their time and energy, sharing their intelligence in my research endeavour. There are far too many people to thank, without whom this project would not have materialised.I am fortunate to have received several years of funding from an interdisciplinary research program called 'Towards Environmentally Sustainable and Equitable Palm Oil' funded by the Interdisciplinary Research and Education Fund (INREF) of Wageningen University. When I started considering PhD research, I could not imagine that I would finally embark on a sixyear journey of research and writing. I would say that in these six years, it has been a luxury to spend most of my time working as a researcher, while also struggling to secure a livelihood from short-time assignments.
