| Abstract: | This article described a comparative analysis of alternative methods of constructing composite indicators to measure the sustainability of the agricultural sector. The three methods employed were Principal Component Analysis, the Analytic Hierarchy Process and a Multi-Criteria technique. Based on the comparison focused on the irrigated agriculture of the Duero basin in Spain as a case study, it is used a dataset of indicators previously calculated for various farm types and policy scenarios. It is established a hierarchy of preferred policy scenarios on the basis of the level of sustainability achieved and showed that the most recent CAP reform was the most sustainable agricultural policy scenario. The author argued that full-time farmers with small to medium-sized farms and sowing profitable crops are the most sustainable farm types in all the policy scenarios. |
