The exploration began when a series of coincidences led me to the Basque Centre for Climate Change Centre (BC3). I had considered doing a PhD since the beginning of my professional career, but the long duration of a PhD and focusing on a particular topic discouraged such intentions. After some years working in the private sector, I realised I still had much to learn. For this reason, I applied for and subsequently received a grant for an MSc programme on soil and water management and then, in 2010, I obtained a grant to go to Ghana, working as a consultant in the UNESCO’s office in Accra. My time there made me realise that doing a PhD transcended becoming an expert in a topic. Through various positions, I shared time with politicians and professors from whom I learned that the personal and technical skills gained from pursuing a PhD were invaluable; consequently, I aspired to incorporate these aptitudes in my own self-development. Thereafter, I explored PhD opportunities, preferably in the Basque Country, as I had been studying and working abroad, and I was keen on understanding my native land. I had the opportunity to work in the BC3, but the former scientific director suggested that I pursue an additional master’s degree in economics. After reviewing several master’s programs and speaking with different professors, I understood that the masters of ecological economics offered at ICTA-UAB provided a new scientific paradigm, one of complexity, and from a notably socially and environmentally-committed perspective. It was a crucial moment of lucidity when I realised that I had to bridge those areas (the land/ecosystems dimension with the social dimension) to build my own research career. During the MSc programme at ICTA, I discovered political ecology and my enthusiasm amplified. This knowledge acquisition shaped the ideas which I then began to develop for my PhD. After completing the MSc at ICTA, I moved home and started the PhD in Bilbao with Unai Pascual. I have spent all my PhD years there, making at least one visit per year to Barcelona, where I typically spent several days with Esteve Corbera discussing PhD issues and ideas. I must admit that the early years were challenging, when after reading so much information, I was still unable to properly formulate the research questions of my thesis. I felt a bit lost, but this way of proceeding also allowed for a more creative and thought-invoking process, where I developed my own interests through my personal learning on an iterative basis. The camaraderie of BC3 and ICTA colleagues and their unconditional support have made this learning process much more dynamic and productive. By the end of the first year, I moved to Lund, Sweden, supported by EcoFINDERs project funds, an EU- funded program on Ecological Function and Biodiversity Indicators in European Soils in which Unai was involved. It was in September 2012 when I developed the ecological aspects of my ideas with the i help of Katarina Hedlund’s team in the Department of Biology of Lund University. More specifically, I assessed the effects of different types of land management practices on the soil properties and the trade-offs and synergies of soil ecosystem services (ES) under different intensities of land management. I greatly value the learning experience that I received from my participation in this group regarding statistics and understanding ecological processes. The product of this collaborative work resulted in publishing the first article of this thesis. However, I have not included it within the dissertation. The cases of Sweden and Navarre are completely different, as the Swedish case was conducted under controlled conditions (which focused on rotations of crop varieties and the amount of mineral fertilisers used), whereas the Navarre case encompassed a broad quantity of crops and land management practices, including in turn different crop varieties (not considering rotations), types of fertilisers (not considering quantities) and use of irrigation. Initially, I intended to make two separate sections addressing each case study, but as my research thinking evolved, I decided to focus the dissertation on Navarre only, in order to produce a more coherent and less convoluted thesis. The research process has been anything but linear. The learning path has been cyclical and has been continuously adapted to emerging ideas and reflections, to questions and debates arising through in- depth research. I dedicated approximately one year intermittently to fieldwork, which has been the best part of the PhD. Another year was devoted to analysing the Navarre case study results using R, which was a challenging learning process. Lastly, I dedicated a year or more on writing. Combining all the pieces together and communicating results with fluidity has been more arduous work than first expected. I hope to have succeeded in constructing an interesting research narrative, and that the final reading reflects the long and stimulating journey it entailed. I hope you enjoy and learn from it as much as I have. Amaia Albizua Aguinaco ii Peer-reviewed journal publications Albizua, A., Williams, A., Hedlund, K., Pascual, U. 2015.
