Crecimiento económico y exclusión social en la agricultura familiar argentina
(Universitat Politècnica de València, 2001) Lattuada, Mario; Moyano Estrada, Eduardo
[EN] This article focuses on the process of economic growth that Argentina underwent during the nineties and its effects on the Pampeana region’s farming sector. Its main goal is to contribute, from a sociological point of view, to the debate on the possibilities and limitations of family agriculture to reproduce itself in a context characterized by the implementation of structural ajustement programs. Firstly, the article describes the evolution of the most important economic indicators of Pampeana farming sector during the last decade. Secondly, it points out the different elements which both provoked the deterioration of the small farmers’ incomes and increased its social and economic weakness. Thirdly, it shows the growing debtment of Pampa farmers and, consequently, the reduction of the number of farms in that region. Finally, the authors offer some ideas on the process of social exclusion of small and middle farmers in a context of open markets where the role of the State is restricted. From starting of the European experiences, they propose changes for agricultural policies to be more sensitive to the social dimension of sustainability.
Análisis del efecto de los mercados de agua sobre el beneficio de las explotaciones, la contaminación por nitratos y el empleo eventual agrario
(Universitat Politècnica de València, 2001) Calatrava Leyva, Javier; Garrido Colmenero, Alberto
[EN] The evidence available about the external effects of functioning water markets is ambiguous. While some authors have shown that water exchanges diminishes the polluting effects of irrigated agriculture, others conclude otherwise. The joint use of contaminant input taxes and the establishment of water markets gives rise to ambiguous results, because water and fertilisers are not substitutes. The objective of this paper is to examine the joint effects of establishing an hypothetical spot water market among farmers and a nitrogen tax on irrigators’ benefits, nitrogen pollution and hired external labour. Two non-linear models are formulated and developed that simulate irrigators’ behaviour and the functioning of inter-district water markets in the Guadalquivir basin. Results show that water markets would increase hired farm labour and irrigators’ surplus, though at the cost of increasing nitrates pollution. The reduction of nitrates contamination achieved by the tax is attenuated as a result of water exchanges, which in turn contribute to reduce the negative income effects caused by the nitrates tax. Water markets increase unambiguously the social benefits resulting from increasing hired labour.
Comparación de la ordenación contingente y del experimento de elección en la valoración de las funciones no privadas de los bosques
(Universitat Politècnica de València, 2001) Mogas Amorós, Joan; Riera, Pere
[EN] This paper presents a comparison between two stated preference methods: the contingent ranking and the choice experiment. An empirical application is included, involving the valuation of the effects that would have a specific program to convert some agricultural land into forest land in Catalonia. The valuation exercise considers a forest recreational function, carbon storage, and erosion protection. The results show some differences between the values derived from the two methods, with the choice experiment values being significantly greater. Moreover, the differences are kept when comparing pairwise observations derived from the choice experiments with simulated pairwise observations derived from the contingent ranking.
Política agrícola y competitividad. Efectos de sistemas alternativos de ayudas
(Universitat Politècnica de València, 2001) Atance Muñiz, Ignacio; Bardají Azcárate, Isabel; Tió Saralegui, Carlos
[EN] The Agenda 2000 reform of the Common Agricultural Policy (CAP) justifies public intervention in agriculture in the basis of two main objectives: increasing the competitiveness of European agriculture and its multifunctional role. This paper attends to assess the ability of the reform to address this first objective. Competitiveness is considered both as the capacity to adopt new technologies and to restructure land holdings towards those more efficient. Mathematical programming models simulating the adoption of new technologies by selected representative farms have been constructed for two Spanish agricultural areas – Tierra de Campos of Valladolid and Campiña Baja of Córdoba. The simulation has included not only Agenda 2000 and the previous intervention system, but also three alternative policy scenarios. Relative results between scenarios allow to evaluate the size of the incentive introduce by each intervention system to adopt new technologies or promote structural reforms.
Los derechos de propiedad en la agricultura de regadío: Su situación frente al cambio institucional
(Universitat Politècnica de València, 2001) Ortiz Miranda, Dionisio; Ceña Delgado, Felisa; Dpto. de Economía y Ciencias Sociales; Escuela Técnica Superior de Ingeniería Agronómica y del Medio Natural; Grupo de Investigación de Economía Internacional y Desarrollo
[EN] The Spanish water economy is within a process of institutional change. The development of this change will be strongly conditioned by the water property rights structure, and this structure –in the context of irrigated agriculture- is defined by a complex net of informal institutions and farmers’ perceptions. The objective of the article is to characterise these property rights –through previous desegregation of its content- in the context of Irrigation Districts of the Guadalquivir basin, in order to analyse how the new institutions could be performed in this environment. Results, based in both the analysis of formal institutions and farmers’ opinion, show (i) the lack of adaptation of new institutions to farmers’ demands, and (ii) some characteristics of the property rights structure which could hinder the institutional change.
