The impact of environment policies on carbon absorption by forest ecosystems
(Universitat Politècnica de València, 2002) Díaz Balteiro, Luis
[EN] Since recently forest ecosystems has been included as possible sinks of the atmospheric CO2, the establishment of new forest plantations is mentioned as a measure to mitigate the concentrations of this gas. This capacity would take to assess environmental objectives into afforestations programs. Under the optics of a private landowner or a possible investor in this kind of assets, these circumstances turn decision-making process into a joint production case, different to the traditional management of these forestations. On the other hand, from a social point of view the capture of carbon would be at his maximum. Two possible cases of afforestations have been discussed, and the results show that the current system of European grants cannot constitute an optimal solution, since to add new grants to those existent it won't cause bigger carbon storage, but only an increase in the landowners’ revenues.
Shocks caused by the new CAP: strategic adjustment decisions in Andalusian agricultural systems
(Universitat Politècnica de València, 2002) Gallardo Cobos, Rosa; Ramos Real, Fernando; Ramos Real, Eduardo
[EN] The reforms of the Common Agricultural Policy (CAP) have selected instruments to protect continental crops, which are different from those used to support Mediterranean products. This fact has also led to different adjustment farming strategies. On the other hand, in areas where both types of products coexist, farmers are subject to conflicting instruments leading to contradictory economic rationale; this, in turn, poses an obstacle to pretended adjustment and modenisation processes. This paper approaches the analysis of the effects of the CAP reforms on some agricultural Andalusian systems which are endowed with both continental (mainly grains) and Mediterranean (mainly olives) products. Observed strategies seem to indicate that a large majority of farmers are inclined to consider decisional economic variables which tend to give priority to short term plans to maximize cash vis a vis the long run approach which seeks to remunerate all productive factors. Some indicators related to competitiveness are defined to quantify the above mentioned strategies. Using the results obtained for 1.998 some sensitivity tests are applied to Andalusian agricultural systems, referred above, during the period of the Agenda 2000; i.e. from 2000 to 2006.
Credence attributes standards and certification. A comparison of vegetable standards
(Universitat Politècnica de València, 2002) Compes López, Raúl; 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] European consumers are demanding more trust attributes for the safety of products and the origins or methods of the food production chain. The supply of these attributes in the optimal quantity makes it necessary and very often the participation of a third party: the government if there are externalities derived from consumption and production of these attributes, i.e. through obligatory standards, or an independent entity to certify the fulfilment of a voluntary standard. In the vegetable sector, in general, and in the fresh tomato production, in particular, the number of these obligatory norms and voluntary standards has raised considerably in the last few years. This proliferation has created a problem of information and knowledge for consumers and producers, who need to know the differences in order to decide what to do. By comparing the main voluntary standards, we see that the greatest coincidences are established in the food security chapter. Therefore, there are more demanding standards due to a greater number of fixed requirements and a higher exigency level. EUREPGAP and AENOR are the more complete standards. The first has the advantage of reducing the transaction costs between the promoting supermarkets and their vegetable suppliers and, at the same time, is becoming a barrier for selling to them.
Identification of strategic groups in the Spanish fruit and vegetable sector
(Universitat Politècnica de València, 2002) García Martínez, Marian; Poole, Nigel; Del Campo, Francisco; López, David
[EN] This article reports the results of an intra-industry study that seeks to identify empirical regularities between firm strategy, management style, organisational structure and performance in the Spanish fresh fruit and vegetable industry using strategic group analysis. Groups were formed from key dimensions reflecting firms’ strategic orientations. Performance levels did not differ systematically between strategic groups, but performance was found to be influenced by the alignment between entrepreneurial culture and organisational structure. A move towards greater flexibility and/or adopting an entrepreneurial style are both likely to contribute to an improvement in the overall performance of the firm.
Underground water management in the West Mancha aquifer
(Universitat Politècnica de València, 2002) Iglesias Martinez, Eva
[EN] This research focuses on the particular problem that emerges in overexploited aquifers when environmental externalities are present. This is the case of Mancha Occidental where environmental externalities derive from the interrelation of groundwater reserves and the preservation of Tablas de Daimiel wetlands. Several mathematical programming models are developed to evaluate alternative groundwater management policies aimed to assure the preservation of the wetlands. The results permit to argue that the Gisser-Sánchez rule, which states that gains derived from optimal management in groundwater are not significant, may be questionable. Moreover, the results show that differences in groundwater management policies are strongly determinant. In the first place, it has to be emphasized that a fix quota system could result in significant inefficiencies, both from the agricultural sector perspective and from the environmental perspective. Secondly, a payment system implemented to compensate the application of water quotas might cause undesired long term effects, as its relative compensation value will diminish as the aquifer’s recovery level increases. Finally, the results show that a water banking system may contribute to reconcile farmers´ interest and the preservation of the wetlands.
