Insects, especially bees, mediate the production of about 75% of crop plants consumed worldwide, and smallholders in the tropics produce about 40% of the world’s food. Both bees and traditional small-scale production systems are threatened because of the expansion of industrial agriculture. In this dissertation I aim to understand how agrarian change – the transformation from traditional to industrial agriculture– has influenced the relationships between humans and bees through effects on Anolaiman livelihoods and landscapes. In doing so, I re-construct the environmental history of the region and describe socio-economic, cultural and ecological drivers and trajectories of socio-ecological change shaping the current state of Anolaima. To evaluate the interdependence between humans and bees, I evaluate the contribution of animal pollinators to rural livelihood security. I find that local socio-economic asymmetries associated with agrarian change influenced food access in Anolaima in such a way that pollination deficits could disproportionately affect poor households, while nutrient-rich, animal-pollinated crops become luxury foods. To understand the effects of environmental change on bees, I assess the influence of agricultural management and habitat factors at the local and landscape scales on bee diversity, and vii find that bee communities are undergoing a process of biotic homogenization associated with environmental change. This empirical and interdisciplinary study represents a holistic understanding of bee declines and its emergence from multiple layers of socio-cultural, economic, political and environmental dynamics associated with agrarian change, an urgent issue with important implications for food security throughout the world. viii Acknowledgements Ithaka C.P. Cavafy (Translated by Edmund Keely) As you set out for Ithaka hope your road is a long one, full of adventure, full of discovery. Laistrygonians, Cyclops, angry Poseidon—don’t be afraid of them: you’ll never find things like that on your way as long as you keep your thoughts raised high, as long as a rare excitement stirs your spirit and your body. Laistrygonians, Cyclops, wild Poseidon—you won’t encounter them unless you bring them along inside your soul, unless your soul sets them up in front of you. Hope your road is a long one. May there be many summer mornings when, with what pleasure, what joy, you enter harbors you’re seeing for the first time; ix may you stop at Phoenician trading stations to buy fine things, mother of pearl and coral, amber and ebony, sensual perfume of every kind— as many sensual perfumes as you can; and may you visit many Egyptian cities to learn and go on learning from their scholars. Keep Ithaka always in your mind. Arriving there is what you’re destined for. But don’t hurry the journey at all. Better if it lasts for years, so you’re old by the time you reach the island, wealthy with all you’ve gained on the way, not expecting Ithaka to make you rich. Ithaka gave you the marvelous journey. Without her you wouldn't have set out. She has nothing left to give you now. And if you find her poor, Ithaka won’t have fooled you. Wise as you will have become, so full of experience, you’ll have understood by then what these Ithakas mean. x When I decided to leave Colombia to study abroad, I did not contemplate the many ways in which my life would change. All the challenges, beautiful people, celebrations, refusals, and achievements have been opportunities to learn. I am grateful that life has given me so many opportunities. I truly hope I can share the privileges of experiencing all what has come to my life with others, especially with those less privileged, many times forgotten. After I left to conduct fieldwork in Anolaima, I asked myself whether it was a good idea to renounce to the expectations of “my world” for two years. Experiencing a different reality with all its challenges and opportunities was a great gift brought by this dissertation. My fieldwork season was the best–and perhaps the only–way to learn about the infinite generosity, warmth and great sense of humor of peasants; the deep reasons for their supposed irrationality; the wonder and potential of a child holding a camera; and the wisdom and strength of spirit someone develops after a lifetime of apparent failure and indisputable marginalization. I learned about hope, joy, collaboration, and life priorities with farmers; and faced fears, reflected about the limits and consistency of my practices as a scientist, and re-learned how my family is “my team.” I have uncountable and unforgettable lessons; all of it was worth it. To all the farmers, beekeepers and people in Anolaima who shared pieces of their lives with me: I have no words to define my immense and absolute gratitude. You helped me grow as a person in ways I could have not imagined, and made me dream – xi now realistically– about building a reality in which we all can coexist. To Ceineth Murcia, Angelita, Santi and Simón: thanks so much for your friendship and trust, and for letting me stay with you during the first months
