European water policy, as set out in the Water Framework Directive (WFD), requires all EU Member States to implement volumetric water pricing at rates that roughly cover the total costs of providing water services. The objective of this paper is to develop a methodology that, for the different farmtypes in an irrigable area, will enable us to analyse the(More)
volume 28 number 8 AuGuST 2010 nature biotechnology We first compiled a database of crossfertilization rates and distance by collating different publications and unpublished studies on maize cross-fertilization, to obtain a total of 1,174 observations covering four European countries (Germany, Italy, Spain and Switzerland). Details on the sources of data(More)
This paper describes 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. The comparison focused on the irrigated agriculture of the Duero basin(More)
This article analyses European Union (EU) farmers' attitudes towards adoption of genetically modified crops by identifying and classifying groups of farmers. Cluster analysis provided two groups of farmers allowing us to classify farmers into potential adopters or rejecters of genetically modified herbicide-tolerant (GMHT) crops. Results showed that(More)
[1] European water policy requires all EU Member States to implement volumetric water pricing at rates that roughly cover the total costs of providing water services. The objective of this paper is to develop a methodology that will enable us to analyze the differential impact that a water pricing policy for irrigation would have on heterogeneous farmers of(More)
In modelling farm systems it is widely accepted that risk plays a central role. Furthermore, farmers’ risk aversion determines their decisions in both the short and the long run. This paper presents a methodology based on multiple criteria mathematical programming to obtain relative and absolute risk aversion coefficients. We rely on multiattribute utility(More)
The agricultural sector is having an increasing impact on water resources in Spain, both from a quantitative (consumption) and qualitative (pollution) point of view. Therefore, the implementation of the Water Framework Directive (WFD) will have a deep impact on this productive sector. In fact, new river management plans are aiming to reduce these pressures(More)
