Effects of elevated atmospheric CO2 on soil organic carbon dynamics in a mediterranean forest ecosystem.

REA Auditado

Elevated atmospheric CO 2 has the potential to change the composition and dynamics of soil organic matter (SOM) and consequently C and N cycling in terrestrial ecosystems. Because of the long-lived nature of SOM, long-lasting experiments are required for studying the effect of elevated CO 2 on soil organic matter dynamics.

Hierarchical levels in agro-ecosystems: selective case studies on water and nitrogen.

REA Auditado

The subject of this thesisToday, agronomic research faces the triple challenge to develop knowledge and insight to manage agro-ecosystems which are inherently sustainable, to diminish the undesirable side effects and to meet the increasing demand of food of a still growing world population, without claiming all the available land. Sound management of agro-ecosystems is not solely a matter of the individual farmer, nor of only field and farm level. Local, national and international policy levels demand guidance from the agricultural research community in management of the natural resources.

Conservation scenarios for olive farming on sloping land in de Mediterranean

REA Auditado

The future of olive farming on sloping land in the Mediterranean is uncertain. Sloping and Mountainous Olive Production Systems (SMOPS) that have been sustainable for ages have in a relatively short time frame witnessed major changes. Although remnants of many of these traditional landscapes still exist today, the general trend is different.

Biodiversidad de sírfidos (Diptera: Syrphidae) y conservación de los hábitats en el Parque Nacional de Cabañeros, España

REA Auditado

El alto potencial de los insectos como herramientas para la conservación y gestión de la biodiversidad está infravalorado. Los sírfidos (Diptera: Syrphidae) destacan, entre otras cosas, por su carácter bioindicador del estado de conservación de los hábitats. No obstante, la fauna de sírfidos de la parte occidental de la Cuenca Mediterránea, está insuficientemente estudiada y los ciclos biológicos de muchas especies raras, amenazadas o endémicas se desconocen.
Este estudio se ha desarrollado en un ecosistema mediterráneo típico, el Parque Nacional de Cabañeros (España).

Linkages of dietary patterns, international trade and land use: the case of olive oil in the European Union

REA Auditado

Within only two decades olive oil developed from a niche product which could hardly be found in food stores outside the producing regions towards an integrated component in the diets of industrial countries. This paper discusses the impacts of the promotion of the “healthy Mediterranean diet” on land use and agro-ecosystems in the producing countries. It examines the dynamics of olive oil production, trade and consumption in the EU15 in the period 1972 to 2003 and the links between dietary patterns, trade and land use.
