In this article, the agricultural sector in Romania provides the basis of a sociological enquiry into the contribution of statistics to the definition of legitimate economic organization. Using the analytical tools developed by James C. Scott, the emphasis is laid on the Farm Accountancy Data Network (FADN) developed by the European Commission to define ‘economically viable’ farms. The measurement units which the FADN provides are applied at national level to determine legitimate agricultural practices. This imposes a productivist definition of the agricultural economy which diverges from the modes of social and economic organization observed in rural areas in Romania. Four million Romanian citizens make their living directly from working the land. The majority own smallholdings received during decollectivization and practise subsistence farming at the fringes of the legal economy. Instead of employing a definition of agriculture consistent with their practices and developing local distribution channels, quantification instruments provided by the European Commission form the basis of a selection procedure among these smallholders. These instruments have enabled the Romanian Ministry of Agriculture to set a threshold of ‘economic viability’ below which producers are deemed unable to develop a commercial approach to their activities. The objective is to help those who just about reach the required level to consolidate their agricultural holdings and take up intensive farming. The remainder are disqualified and encouraged to leave the sector. To further this objective, the category ‘semi-subsistence’ agriculture has been created and takes centre stage in all measures implemented. Nevertheless, the statistical dividing lines on which this category is based have no substance and the structure of agriculture is manifesting high levels of inertia< Réduire
