1	Envisioning Agribusiness: Land, Labour and Value in a time of Oil Palm Expansion in Indonesia Bissonnette, Jean-Francois 05 March 2014 (has links) The thesis examines the social and economic implications of large-scale agribusiness expansion in Indonesia by analyzing how this economic system, as it is envisioned and materialised, reshapes livelihood possibilities. Based on original interviews with oil palm plantation workers, plantation company officials, smallholders, and on secondary research, this thesis scrutinises the forms of knowledge and practices that constitute large-scale oil palm agribusiness. While oil palm agribusiness produces economic opportunities for groups of individuals from certain social categories, it constrains the prospects of others in systematic ways. Oil palm agribusiness, as a project and as a set of practices, is deployed by a broad range of economic actors at different scales in an attempt to govern access to resources. However, the power of oil palm companies and investors over land, labour, and value is contested and negotiated by workers and smallholders who engage creatively with this economy. The thesis shows that oil palm agribusiness forms a field of power that produces specific subjectivities which transform the meanings and constraints related to this mode of production. The first part of the thesis (chapters 2 and 3) identifies the objectives pursued by those who plan and envision oil palm agribusiness. I emphasise that oil palm agribusiness serves a number of often competing and shifting aims that range from capital accumulation to welfare provision. The second part of the thesis (chapters 4 and 5) demonstrates how the modes of visioning examined in the first part of the thesis produce a broad set of material conditions for populations. I analyse the ways in which these conditions are constantly reshaped by everyday power relations and articulated around the value of labour and land. Based on ethnographic fieldwork that I conducted in West Kalimantan, Lombok, and Nias, these chapters shed light on the lived geographies of labour and the livelihood strategies used by individuals and social groups in the space of oil palm agribusiness. 0366
