| En este trabajo se presenta un enfoque metodológico para el análisis de presiones e impactos de la aplicación conjunta de diferentes escenarios de política agraria y de tarifación del agua de riego. Para alcanzar dicho objetivo se asume que los agricultores consideran distintos criterios en la gestión de su actividad productiva. En este contexto decisional se utilizan modelos de programación matemática basados en la Teoría de la Utilidad Multiatributo (MAUT), de modo que pueda simularse el comportamiento de los agricultores en el futuro. Como resultado de dicha simulación no sólo se obtienen las variables de decisión de los agricultores (planes de cultivos), sino también un conjunto de indicadores económicos, sociales y ambientales que serán de utilidad... |

| 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... |

| 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... |

| 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 analyses the demands from the society of Castilla y León (Spain) regarding its agricultural sector through the valuation of the relevance of its productive and non-productive functions. Additionally, it assesses the level of social satisfaction concerning the performance of these functions by irrigated agriculture in this region. For this purpose primary data colleted through a survey has been used. Results obtained show that the average citizen does not perceive a higher utility from irrigated agriculture compared with the whole agricultural sector. For these agricultural systems the social function is the element of multifunctionality considered most relevant regarding the perceived social welfare. Resumen Este trabajo analiza las demandas... |

| La presente investigación tiene como objetivo principal el desarrollo de una propuesta metodológica de planificación multicriterio con el fin de optimizar el uso de la tierra con fines agrarios en áreas protegidas tropicales. Para ello se han empleado las técnicas del Proceso Analítico Jerárquico (AHP) y la programación compromiso (PC), considerado objetivos de carácter económico, ambiental y social. La aplicación empírica desarrollada se ha centrado en un área protegida de Venezuela con tradicional vocación agraria. Los resultados de la planificación evidencia la existencia de importantes conflictos entre los objetivos planteados, así como la necesidad de la intervención pública para lograr un desempeño del sector agrario en concordancia con las... |

| The objective of this paper is to carry out a foresight analysis of the agricultural sector in Castilla y León (Spain) for 2020. The methodology used to build the various scenarios is prospective analysis. We first performed a structural analysis in order to identify the key driving forces that characterize the evolution of the sector in this region (agricultural production, demand for agricultural products and institutional framework). We then carried out a morphological analysis that generated a range of “partial scenarios” from which we finally built four “global scenarios”. These last scenarios characterize the possible trends in the variables of change previously identified. Lastly, the common key parameters of each global scenario were quantified 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. |
