Abstract
The following article summarizes the findings of 30 studies on efficiency and productivity of organic farming systems. In a lot of studies organic farms shows a lower productivity than conventional farms, however, we cannot find evidence for a systematic lower efficiency. Environmental variables (if included) show a strong impact on efficiency and productivity of organic farms. We finally discuss conclusions from the productivity and efficiency literature. Keywords: technical efficiency, productivity, organic farming, environmental efficiency
Highlights
The question of how productive and efficient are organic farms are widely discussed
One important outcome of a Stochastic Frontier (SFA) efficiency model in organic farming are ‘output-elasticities of inputs’ which characterize the structure of production, which is a unit-free measure for the impact of one input on the output of a farm
Productivity and efficiency analysis can provide a complete overview on farm performance, going beyond the typical farm-success indicators or partial productivity measures
Summary
The question of how productive and efficient are organic farms are widely discussed. During the last 15 years there has been an increasing number of studies, who explicitly model efficiency and productivity of organic farms. The following short paper summarizes the literature on efficiency and productivity and draws some short conclusions
