Old Tractors, New Policies and Induced Technological Transformation: Agricultural Mechanisation, Class Formation and Market Liberalisation in Ghana
MetadataShow full item record
This article examines the recent uptake of tractor ploughing services in northern Ghana. It examines the historical continuities in mechanisation and the emergence of a class of medium-scale commercial farmers. In the light of this, it questions the thesis that the recent uptake of mechanisation and emergence of medium-scale farmers reflects the successes of market liberalisation. It is critical of neoclassical theories of agricultural transformation rooted in theories of induced innovation and argues for a political economy approach that links agricultural transformation to processes of social differentiation and the historical role of the state in promoting agricultural commercialisation.
