(May 2010) Daniel J. Redo, B.S.; M.S., The University of Southern Mississippi Chair of Advisory Committee: Dr. Andrew Millington The Corredor Bioceánico is a major transportation project connecting the agricultural heartlands of South America to the Atlantic and Pacific coasts. The final link is in southeastern Bolivia – an underdeveloped area that is home to two indigenous groups and globally-significant woodlands and wetlands. Infrastructure developments – comprising a major highway upgrade, revitalized railway services and increased flows along gas pipelines to Brazil – pose major threats to livelihoods and the region‘s ecological integrity. There are two broad objectives: (i) to map and quantify the spatial patterns of land change using a time-series of coarse and medium resolution satellite imagery; and (ii) to understand the socio-economic and political drivers of change by linking household surveys and interviews with farmers; environmental, climatic, and political data; and classified satellite imagery. Overall, large-scale deforestation has occurred along the Corredor Bioceánico for mechanized commercial production of oil-seed crops such as soybeans and sunflower. The significance of these findings is that agriculture-driven deforestation is pushing into sensitive areas threatening world-renowned ecosystems such as the Chaco, Chiquitano iv and Pantanal as well as noteworthy national parks. Though quantity remains relatively small compared to other parts of South America, rates of forest loss match or exceed those of more publicized regions such as Rondônia or Mato Grosso, Brazil. Moreover, rates of forest loss are accelerating linearly with time due to policies implemented by incumbent president Evo Morales. Results also show that in the first years of cultivation, pasture is the dominant land-use, but it quickly gives way to intensively cropped farmland. The main findings in terms of percentage area cleared according to forest type is that farmers appear to be favoring transitional forest types on deep and poorly drained soils of alluvial plains. Semi-structured interviews with farmers and representatives of key institutions illustrate that price determined by the global market is not proportionally the most dominant motive driving LULCC in the lowlands of Santa Cruz, Bolivia – an area seen as a quintessential neoliberal frontier. v ACKNOWLEDGEMENTS This dissertation was funded by the National Science Foundation, SBE DDRI Geography and Regional Science and Office of International Science and Engineering (Grant: BCS-0802672), and was additionally funded by Texas A&M University. I thank both institutions for their support. My particular thanks to Don Lucho Rámirez, who drove me for hours on end on unpaved, dusty, and potholed roads with much good humor; and Phil Bender who patiently set up interviews with farmers, producer organizations, helped with the inevitable translation issues, and helped us achieve one of our holy grails – to interview Mennonite farmers. My advisor, Andrew Millington, challenged me to write a dissertation that was beyond my scholarly ability. I greatly appreciate your ability to serve as a teacher, advisor, mentor, counselor, and friend, and to direct me through the trials and tribulations of the Ph.D. experience. I also thank committee members Christian Brannstrom, Wendy Jepson and Amanda Stronza. Their efforts have been truly instrumental in my academic achievements and my professional development. I would also like to thank my family, whom I love dearly and who have always encouraged me in my endeavors. I would never made it this far without their support and patience. Finally, I thank my wife Katherine, who accompanied me on my first expedition to Latin America many years ago. For me to have adventures is lucky enough, but to share them with a beautiful, intelligent and wonderful woman like her is all a man could ever ask for. You have also been willing to endure the difficulties of student life today for a more promising tomorrow. To all of you, words cannot express vi my gratitude – my accomplishments would not have been possible without your support. I hope that I have made all of you proud. vii NOMENCLATURE ANAPO Asociación de Productores de Oleaginosas y Trigo (Association of Oilseed and Wheat Producers) AVHRR Advanced Very High Resolution Radiometer CAF Corporación Andina de Fomento (Andean Development Corporation) CAO Cámara Agropecuaria del Oriente (Agricultural Chamber of the East) CBERS Chinese-Brazil Earth Resources Satellite DN Digital Number ETM+ Enhanced Thematic Mapper GLCF Global Land Cover Facility HRCCD High-Resolution Charge Coupled Device IADB Inter-American Development Bank IMA Integrated Management Area INPE Brazilian National Space Research Institute IRS Indian Remote Sensing Satellite KINP Kaa-Iya del Gran Chaco National Park LULC Land-Use and Land-Cover LULCC Land-Use and Land-Cover Change MAS Movimiento al Socialismo (Movement Towards Socialism) MERCOSUR Mercado Común del Sur (Common Market of the South) MODIS Moderate Resolution Imaging Spectroradiometer viii MSS Multispectral Scanner MVC Maximum Value Composite NDVI Normalized Difference Vegetation Index NGO Non-Governmental Organization NP National Park LP DAAC Land Processes Distributed Active Archive Center RMSE Root Mean Square Error SEA Strategic Environmental Studies SEF Socio-Economic Function SPOT Satellite Pour l'Observation de la Terre (Earth Observation Satellite) TM Thematic Mapper USGS United States Geological Survey WB World Bank WWF World Wildlife Fund ix TABLE OF CONTENTS Page ABSTRACT .............................................................................................................. iii ACKNOWLEDGEMENTS ...................................................................................... v NOMENCLATURE .................................................................................................. vii TABLE OF CONTENTS .......................................................................................... ix LIST OF FIGURES ................................................................................................... xii LIST OF TABLES .................................................................................................... xvi 1.
