CONTEXT: The adverse effects of land fragmentation on agricultural productivity prompted governments to apply consolidation programs to overcome unfavorable farm structures that impede rationalization of agricultural resource use. In Austria, the total area where land consolidation and voluntary land exchange schemes were ever implemented amounts to more than 40% of the total agricultural area. While the private costs for farmers associated with fragmented land are well understood, the potential benefits of land fragmentation in terms of risk reduction have received much less attention. OBJECTIVE: Using a 2007–2014 panel of Austrian crop farms, we analyze the effect of multiple dimensions of land fragmentation on farms’ production efficiency and risk performance. METHODS: We use Data Envelopment Analysis (DEA), a non-parametric linear programming approach, to estimate efficiencies. Technical efficiency is decomposed into i) scale efficiency, ii) pure technical efficiency, and iii) input-mix efficiency. Risk efficiency, a concept borrowed from modern portfolio theory, measures the performance of a farm relative to a mean-variance frontier. RESULTS AND CONCLUSIONS: A second-stage DEA analysis reveals that farms with fewer plots and a shorter average farmstead to plot distance tend to be more technically efficient. Larger plots allow for better exploitation of returns to scale. The scattering of plots has no statistically significant effect on technical efficiency but provides benefits in terms of higher risk efficiency. Land consolidation projects should carefully weigh the costs and benefits associated with different dimensions of land fragmentation.
