| In this paper we present a methodology to analyse input use in the agricultural sector. The novelty of the theoretical model explained is that it has been developed considering a multi-criteria environment. Thus, the optimal input use condition is determined by the assessment of "multi-attribute utility" and "multi-attribute marginal utility". We show how the approach adopted in this paper is a generalization of the single-attribute expected utility theory. The theoretical model developed is further implemented in an empirical application that studies water for irrigation use as a particular case. Results show how multi-attribute utility functions elicited for a sample of 52 irrigators explain differences on irrigation water use in relative homogenous... |

| This paper presents a methodology for assessing the visual quality of agricultural landscapes through direct and indirect techniques of landscape valuation. The first technique enables us to rank agricultural landscapes on the basis of a survey of public preferences. The latter weighs the contribution of the elements and attributes contained in the picture to its overall scenic beauty via regression analysis. The photos used in the survey included man-made elements, positive and negative, agricultural fields, mainly of cereals and olive trees, and a natural park. The results show that perceived visual quality increases, in decreasing order of importance, with the degree of wilderness of the landscape, the presence of well-preserved man-made elements, the... |

| RESUMEN El presente artículo compara la reforma de la PAC aprobada en junio de 2003 con un hipotético escenario de mayor liberalización en el que se permite la substitución de cultivos COP (cereales, oleaginosas y proteaginosas) por cultivos hortícolas y/o patatas. La simulación se lleva a cabo mediante el cálculo de una función de utilidad multiatributo para cada grupo homogéneo de agricultores: tres grupos en cada una de las tres comunidades de regantes. El método de cálculo de las funciones de utilidad no requiere ninguna interacción con el centro decisor. La validación de los modelos confirma la validez de esta metodología para la simulación de las decisiones de cultivo de estos productores. Los resultados sugieren que con el sistema alternativo... |

| Following the decoupling of the cotton subsidies in 2006 the production system has become less intensive in input usage with an average yield reduction of 40 per cent. Albeit the farm income has not been reduced, the reform has had a negative effect on the economy of some rural areas of Southern Spain, where there are few productive alternatives to cotton, with a 39% reduction of direct farm labour. Besides, the reform has been borne by the ginning industry (60% reduction), the agrochemical suppliers and the auxiliary sector. On the other hand, the environment has benefits from the extensification of the cotton production since three quarter of the production is now carried out under integrated production that implies a reduction in the amount of... |

| Considering the latest reform of the EU's Cotton Regulation of 29th April 2004, which will come into force in the 2006/07 season, we analyse its impact on the cotton production sector of Andalusia. The decoupling of subsidies implies that producers will be entitled to 65 percent of the amount received in the reference period (three years) irrespective of the crop chosen to grow. The remaining 35 percent (slightly higher) is paid as cotton are a payment. In this research, first from a survey carried out in 2004 we obtained six groups of producers using fact or analysis and cluster analysis. Then, based on this characterization, we assess the impact of two policy scenarios: (a) the implementation of the reform without any additional measures, and (b) the... |

| In this work several performance indicators such as the Annual Relative Irrigation Supply (ARIS) and the Irrigation Water Productivity (IWP), have been considered to evaluate the changes in the cotton irrigation management due to the decoupling of the European Union Subsidies. For this purpose, a modern irrigation scheme, the Genil–Cabra Irrigation Scheme (GCIS) located in Southern Spain, has been selected. The total irrigated area is 6,900 ha with wheat, olive and cotton as the main crops. The irrigation season 2004/05 was the period when the crop pattern and water management trend changed dramatically. From this year to the present the area cultivated with crops with high water requirements like cotton, sugar beet and maize has been reduced almost by... |

| This paper presents a methodology to evaluate the impact of different policy scenarios using a farmer's utility function. The analysis shows the impact on farmers and on the environment. The case study is a community of irrigated farms (Bajo Carrión) in Northwestern Spain. The results obtained show how Agenda 2000 has little impact on farm crop distribution, gross margins, employment and environment (use of fertilizers and water). The most radical scenario (a 15 per cent COP price cut and no area payments) produces a 37.3 per cent reduction in farm gross margin, and an increase in fertilizer use of 6 per cent. |

| Spanish authorities have recently approved a new legislative framework for the creation of local water markets to improve allocative efficiency for this scarce resource. This paper analyses the potential impacts of the policy. A utility function for three groups of farmers was elicited, using a method that does not require interaction with the decision‐makers. Utility was measured as a function of the first two moments of the distribution of total gross margin. The utility functions were then used to simulate farmers' responses to changes in the price of water. |

| In this paper we simulate changes in crop land allocations made by farmers in Southern Spain due to the implementation of a flat-rate subsidy. In order to reproduce farmers' decision-making process, we first group farmers by farm size into three categories and then elicit a general utility function for each group. The elicitation of the bi-attribute utility functions, based on observed crop land allocation, does not require interaction with the farmers. The results suggest that, with the same EAGGF expenditure, small and medium-sized farms in this region would benefit from this alternative scheme in terms of higher expected total gross margin, flexibility and freedom of crop choice. The new scheme reduces control and monotoring responsabilities for Member... |
