F.  aCrop farm development in the Brazilian Cerrado regionban ex-ante evaluation.  aEdinburgh: University of Edinburghc1990  a268p.  aTese Doutorado.  aSome large commercial farms have been established in the "Cerrado" region due to a large amounts of subsidised capital being made available for special projects, (Franz et aI 1985). However, the appropriate use of technological packages indicated by research stations, on a large number of other Brazilian farms, has been limited by factors which include the difficulties the farmers face in borrowing capital for basic investments (such as: adequate soil fertility correction and soil conservation measures). This has consequently resulted in lower yields at the national leveI.  Analysis of some of the technologies recommended by  CPAC/EMBRAPA(1) for each enterprise at the farm leveI, did  not indicate alI the possible implications and results. Factors which have been excluded from analysis include economic, environmental and social aspects and their interactions with the technological recommendations.  Given that capital is a scarce resource, its use must be rationalised to ensure the effectiveness, of agricultural development, in the "Cerrado" region. Thus, research should be carried out in an inter-disciplinary manner to explore investment alternatives available to farmers.  The proposed study will analyse different sets of producer decisions aimed at developing an optimal investment schedule while at the garoe time maintaining adequate working capital for ongoing activities and living expenses.
