The changing nature of diplomacy poses new challenges for diplomatic actors in the 21st century, who have to adapt their structures in order to remain relevant on the international stage. The growing interdependence and complexity of issues necessitate a more networked approach to diplomacy, while states retain their predominance in diplomacy. The main underlying challenge of modern diplomacy therefore requires finding a balance between traditional and new elements. This paper examines to what extent the European External Action Service (EEAS) meets the new challenges of modern diplomacy and copes with the diverse interests of the other stakeholders involved, namely the institutions and Member States of the European Union (EU). On the basis of a conceptual framework of modern diplomacy and an analysis of the different aspects of the EEAS’ structures, the paper argues that the EEAS does not fully meet the new challenges to diplomacy, since the interests of the other stakeholders put constraints on its free development. The latter therefore have to choose between irrelevance and integration with regard to EU foreign policy and the future of the EEAS.

The European Union (EU) is widely acknowledged as a successful example of economic and political integration of nation states today – a slate of democratic institutions such as the European Parliament have also been developed and European citizens now possess extensive political and civil rights by virtue of the introduction of European citizenship. Nevertheless, the EU is said to suffer from a so called “democratic deficit” even as it seeks deeper and closer integration. Decades of institutional design and elite closed-door decisions has taken its toll on the inclusion and integration of European citizens in social and political life, with widening socio-economic inequalities and the resurgence of extreme-right parties during in the wake of the debt crisis in the Eurozone. This paper attempts to evaluate the democratic development of the EU through the use of a process-oriented approach, and concludes at the end with discussions on the various options that the EU and its citizens can take to reform democratic processes and institutions in Europe.

The aim of this thesis was to evaluate historical change of the landscape of Madeira Island and to assess spatial and temporal vegetation dynamics. In current research diverse “retrospective techniques”, such as landscape repeat photography, dendrochronology, and research of historical records were used. These, combined with vegetation relevés, aimed to gather information about landscape change, disturbance history, and vegetation successional patterns. It was found that landscape change, throughout 125 years, was higher in the last five decades manly driven by farming abandonment, building growth and exotic vegetation coverage increase. Pristine vegetation was greatly destroyed since early settlement and by the end of the nineteenth century native vegetation was highly devastated due to recurrent antropogenic disturbances. These actions also helped to block plant succession and to modify floristical assemblages, affecting as well as species richness. In places with less hemeroby, although significant growth of vegetation of lower seral stages was detected, the vegetation of most mature stages headed towards unbalance between recovery and loss, being also very vulnerable to exotic species encroachment. Recovery by native vegetation also occurred in areas formerly occupied by exotic plants and agriculture but it was almost negligible. Vegetation recovery followed the successional model currently proposed, attesting the model itself. Yet, succession was slower than espected, due to lack of favourable conditions and to recurrent disturbances. Probable tempus of each seral stage was obtained by growth rates of woody taxa estimated through dendrochronology. The exotic trees which were the dominant trees in the past (Castanea sativa and Pinus pinaster) almost vanished. Eucalyptus globulus, the current main tree of the exotic forest is being replaced by other cover types as Acacia mearnsii. The latter, along with Arundo donax, Cytisus scoparius and Pittosporum undulatum are currently the exotic species with higher invasive behaviour. However, many other exotic species have also proved to be highly pervasive and came together with the ones referred above to prevent native vegetation regeneration, to diminish biological diversity, and to block early successional phases delaying native forest recovery.

We use a suite of eight ocean biogeochemical/ecological general circulation models from the MAREMIP and CMIP5 archives to explore the relative roles of changes in winds (positive trend of Southern Annular Mode, SAM) and in warming- and freshening-driven trends of upper ocean stratification in altering export production and CO2 uptake in the Southern Ocean at the end of the 21st century. The investigated models simulate a broad range of responses to climate change, with no agreement ona dominance of either the SAM or the warming signal south of 44° S. In the southernmost zone, i.e., south of 58° S, they concur on an increase of biological export production, while between 44 and 58° S the models lack consensus on the sign of change in export. Yet, in both regions, the models show an enhanced CO2 uptake during spring and summer. This is due to a larger CO 2 (aq) drawdown by the same amount of summer export production at a higher Revelle factor at the end of the 21st century. This strongly increases the importance of the biological carbon pump in the entire Southern Ocean. In the temperate zone, between 30 and 44° S all models show a predominance of the warming signal and a nutrient-driven reduction of export production. As a consequence, the share of the regions south of 44° S to the total uptake of the Southern Ocean south of 30° S is projected to increase at the end of the 21st century from 47 to 66% with a commensurable decrease to the north. Despite this major reorganization of the meridional distribution of the major regions of uptake, the total uptake increases largely in line with the rising atmospheric CO2. Simulations with the MITgcm-REcoM2 model show that this is mostly driven by the strong increase of atmospheric CO2, with the climate-driven changes of natural CO2 exchange offsetting that trend only to a limited degree (~10%) and with negligible impact of climate effects on anthropogenic CO2 uptake when integrated over a full annual cycle south of 30° S.
