ACKNOWLEDGEMENTS I am grateful to my dissertation chair, Dr. James Boyce, for all his guidance, kindness, and support in every process of this dissertation. I would also like to extend my gratitude to Dr. Michael Ash and Dr. James Hafner, my dissertation committee members. I would also like to thank Dr. Eric Baran for introducing me to the Lower Sesan 2 hydropower project and connecting me with the Challenge Program on Water and Food (CPWF) Mekong team. My meeting and conversation with Dr. Ian Baird in Laos was a helpful step for this dissertation. A big thank you to Ms. Yumiko Kura of WorldFish Center Cambodia, project leader of the CPWF Mekong-MK 2: Water Valuation Project, for introducing me to the works of CPWF Mekong and supporting me in undertaking the Lower Sesan 2 hydropower project as a case study. Also, I am grateful for all her help in sponsoring me to the International Forum on Water and Food in South Africa, arranging my field visit to Stung Treng province, and recommending me as a grantee for the Mekong Program on Water, Environment and Resilience (M-POWER) fellowship. I want to thank Dr. Claudia Ringler of the International Food Policy Research Institute (IFPRI) for sending me the spreadsheet of primary data. Thank you to Mr. Samonn Mith who helped me with translation and coordination of my field visits in Cambodia. I would also like to thank Dr. Sokhem Pech, my mentor under the M-POWER fellowship program. I am grateful for the opportunity and financial supports I got in my PhD study from the v Royal Thai Government scholarship, M-POWER fellowship, and the Political Economy Research Institute (PERI) fellowship. During my PhD study, I was very lucky to live with people who shared with me a sense of family. I would like to thank my former housemates, Martin Rapetti, Avanti Mukherjee, Joao Paulo De Souza, Benjamin Storrow, Joshua Finn, and Mittens. The wonderful memories you all created when we lived together will always be with me. I am very fortunate to develop friendships with three wonderful friends who always shared with me a good laugh, and always were there for me during my tough times: thank you Jooyeoun Suh, Jessica Carrick-Hagenbarth, and Anilyn Diaz. I also want to thank Thai students of UMass Amherst for all the fun, the food, and the laughs we had, thank you Thai Mafia. Josh Arond helped me go through the last two years of my dissertation stage; his words always assured me that things will get better whenever I had a bad day. I also want to thank the Arond family for welcoming me into their lives. Lastly, I cannot express how lucky and grateful I am to have the love and support from my parents during all these years. vi ABSTRACT COMMON POOL RESOURCES AND RURAL LIVELIHOODS IN STUNG TRENG PROVINCE OF CAMBODIA SEPTEMBER 2014 PITCHAYA BOONSRIRAT, B.S., KASETSART UNIVERSITY M.S., KASETSART UNIVERSITY Ph.D., UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor James K. Boyce This dissertation assesses the contribution of fish and forest products in the livelihoods of villagers in Strung Treng province of Cambodia, as these two common pool resources are threatened by the construction of the Lower Sesan 2 hydropower project. Household survey data collected under the Challenge Program on Water and Food (CPWF) are used in the analysis. It is found that, in general, fish accounts for a higher overall contribution in household’s livelihoods compared to forest products. Fishery products are most important for direct consumption, while forest products are more important for cash income. Across the study area, the households that most heavily extract and depend most on these resources are the relatively poorer households. The households that highly depend on forest products are distinct, however, from the households that highly depend on fish. The results indicate that these households’ livelihoods are vulnerable to changes in the quality of common pool resources or restriction in access to them due to implementation of the Lower Sesan 2 hydropower project. Compensation and income generation vii programs that can ensure food security and substitute for losses of common pool resource-based income are a necessity for impacted households. In addition, further restrictions on accessing common pool resources should be minimized in order to secure rural livelihoods and reduce poverty. viii TABLE OF CONTENTS Page ACKNOWLEDGEMENTS………………………………………………………………………….…………….v ABSTRACT…………………………………………………………………………………………...…………….vii LIST OF TABLES…………………………………………………………………………………….……………xi LIST OF FIGURES……………………………………………………………………………………………….xvi LIST OF ABBREVIATIONS……………………………………………………………………….…………xvii CHAPTER 1.
