Energy productivity and efficiency of the ‘gher’ (prawn-fish-rice) farming system in Bangladesh

摘要: Abstract ‘Gher’ farming is a unique system that incorporates the joint operation of three enterprises: freshwater prawn, fish and HYV rice, expanding rapidly in coastal regions Bangladesh because its proven high income earning potential. In this paper, sustainability evaluated by analysing performance terms energy use applying stochastic distance function approach which revealed interesting unexpected results. The prawn enterprise key component found to be technically inefficient while rice efficient. net balance efficiency ‘gher’ estimated at 18,510 MJ ha−1 1.72 respectively. farmers are operating very level technical (energy) (92%). Diversification amongst enterprises associated with inefficiency. However, larger size enhances efficiency. policy implication can sustained long run provided productivity from remains high. Also, policies support expansion farm sizes will improve
