A Composite Indicator to Measure Agricultural Sustainability
This paper deals with a comparative analysis of alternative methods of constructing composite indicators to measure the global sustainability of the agricultural sector. The comparison is implemented empirically on the irrigated agriculture of the Duero basin in Spain as a case study. For this purpose, the study employs a dataset of indicators previously calculated for different farm types and policy scenarios. The results enable us to establish a hierarchy of policy scenarios on the basis of the level of sustainability achieved. By analysing the heterogeneity of different farms types in each scenario, it is also possible to determine the main features of the most sustainable farms in each case. All this information is useful for the support of agricultural policy design and its implementation, as we attempt to improve the sustainability of this sector.
