It was a journey of many challenges and I would not have made it through without the support of others. Naturally, I thank my supervisors Lenny and Marjolein for guiding me through the process of performing scientific research and reporting it. Additionally, I thank Bart Willers, Tiny Wigman, Maarten Merkus, Eric Marsman and Zeger Stappershoef for the valuable input they gave through the interviews. I am glad to have met such passionate people and I regard your work as highly valuable. Also, thank you for the cover picture, Bart. Many others supported me and I cannot list them all. However, very important factors were: my partner Jelle, my thesis buddies Ingeborg, Merijn and Marjolein, my parents Hannie en Gideon, and Rinske and Petra. I am thankful for being surrounded by such loving people. I could add more people to the list, but it would remain endless. Additionally, I am very glad that I was able to work on the theme of nature and landscape and the use thereof by society. I regard handling nature and landscape as one of the major challenges of our time. Studying this can contribute enormously to sustaining nature, ecosystem services and human life on earth. For now, I wish you a good read, Enjoy your day and enjoy ecosystem services! With kind regards, Nina 5 Summary Temporal changes in the supply of ecosystem services (ESs) are important to address, but they are often neglected. These changes are difficult to assess and their drivers are poorly known. This study therefore demonstrates a method to assess temporal changes in potential supply so to evaluate the used method and this study identifies the effects of governance changes on ES supply in Berg en Dal in the Netherlands over the last two decades. Literature review and stakeholder interviews identified the most important ESs. Land use and land cover (LULC) and their recent changes are assessed from detailed LULC maps from 1997, 2000, 2003, 2007 and 2012. These maps are converted by a matrix method to ES potential supply maps for seven ESs (i.e. water-flow regulation; pest and disease control; pollination; crops; livestock; recreation and tourism; and natural heritage and natural diversity). This allows to calculate potential supply and changes therein for each ES. Additionally, temporal changes in LULC and ESs potential supply are assessed through stakeholder interviews and literature review. The ES maps from 2012 are further validated using stakeholder interviews and reference maps for two ESs. Governance changes, potential and actual drivers of change in ES supply, changes in demand for ESs
