Agricultural Risk Aversion Revisited: A Multicriteria Decision-Making Approach AgEcon
Gomez-Limon, Jose Antonio; Riesgo, Laura; Arriaza Balmón, Manuel.
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 theory (MAUT) to elicit a separable additive multiattribute utility function and then estimate the risk aversion coefficients and apply this methodology to an irrigated area of Northern Spain. The results show a wide variety of attitudes to risk among farmers, who mainly exhibit decreasing absolute risk aversion (DARA) and constant relative risk aversion (CRRA).

ALTERNATIVE APPROACHES ON CONSTRUCTING A COMPOSITE INDICATOR TO MEASURE AGRICULTURAL SUSTAINABILITY AgEcon
Gomez-Limon, Jose Antonio; Riesgo, Laura.
The aim of this paper is to carry out a comparative analysis of alternative methods on constructing composite indicators to measure global sustainability of the agricultural sector. This comparison is implemented empirically on the irrigated agriculture of the Duero basin (Spain) as a case study. For this purpose, this research uses a dataset of indicators previously calculated for different farm-types and policy scenarios. The results allow to establish a hierarchy of the policy scenarios on the basis of the level of sustainability achieved. Furthermore, analyzing the heterogeneity of different farms-types in each scenario, is also possible to determine the main features of the most sustainable farms in each case. All this information is useful in order...

Analisis de escenarios de políticas para la gestion publica en la agricultura de regadio AgEcon
Riesgo, Laura; Gomez-Limon, Jose Antonio.
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...

MULTI-CRITERIA ANALYSIS OF FACTORS USE LEVEL: THE CASE OF WATER FOR IRRIGATION AgEcon
Gomez-Limon, Jose Antonio; Riesgo, Laura; Arriaza Balmón, Manuel.
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...

Sustainability assessment of olive grove in Andalusia: A methodological proposal AgEcon
Gomez-Limon, Jose Antonio; Riesgo, Laura.
Recently the olive sector has had important changes in Andalusia due to both the enlargement and the intensification of farming. The expansion of the olive grove in Andalusia is causing sustainability problems, not only from the socio-economic dimension (profit reduction) but environmental (erosion, water pollution or biodiversity losses). The main objective of this study is to develop a methodology to analyse the sustainability of the olive grove farms in Andalusia. This methodology will allow us to bear with the three dimensions of sustainability (economic, social and environmental) as well as to obtain a precise diagnosis of the olive grove through a selection of a set of indicators. This methodology will be applied in future research works in order to...
