Producing possession: labour, law and land on a Brazilian agricultural frontier, 1920-1945

In this essay I interpret land-access strategies on the mid- twentieth-cent ury Brazilian frontier as the result of local usufruct-based labour relatio ns that manipulated regionally-interpreted land law. Political ecology, New Institutional Economics and bureaucratic institutions literatures inform m y labour-law approach to examine how land-tenure regimes are created, contr olled and maintained. The microeconomics of two labour systems, contractual claim-staking (the preposto system) and share-tenant farming, reduced the transaction costs involved in land claiming, while capitalising on informat ion asymmetries between workers and land claimants. In several instances co ercion was a key element in mobilising labour to create judicially relevant evidence of possession and generate significant rent streams. Land law did not demand such labour relations, but its contradictions encouraged claima nts to use prepostos and share-tenant farmers to produce secure land access . This argument supports the notion, developed within political ecology, th at local conditions (labour relations and uneven geographical information) mediate the influence of regional factors (interpretation and enforcement o f land law). While adopting some concepts from the New Institutional Econom ics, the argument rejects the claim that land title determines land use and other economic behaviour. (C) 2001 Elsevier Science Ltd.
