The present study investigates the relation between urban form and the socio-economic patterns of the resident population in three southern European cities ( Athens, Lisbon and Rome) featured by different processes of urban diffusion. The paper goes beyond the literature on sprawl focused on (residential, income and ethnic) segregation and the different features of the inhabitants of the suburbs and those of the inner cities residents. By integrating multivariate statistics and spatial analysis, a methodology is proposed, based on morphological and socio-economic indicators available at a fine geographical scale. Results show how urban diffusion processes vary widely according to the context, as does the socio-economic profile of the actors, stressing the need to think about different 'southern European alternatives' of sprawl.

ABSTRACT Aim This paper identifies socio-economic driving forces of biodiversity change and analyses their political and economic dynamics by modelling socio-economic parts of three scenario storylines developed for the ALARM (assessing large-scale risks for biodiversity with tested methods) project. In the BAMBU (business-as-might-be-usual) scenario policy decisions already made in the European Union (EU) are implemented and enforced, but no additional measures are introduced. The GRAS (growth applied strategy) scenario describes a future world orientated towards economic growth and complete deregulation. And finally, SEDG (sustainable European development goal) is a normative scenario focusing on the achievement of sustainable development. Methods The GINFORS (global inter-industry forecasting system) model is applied to quantify the effects of different sets of policy measures representing the three scenarios. It allows investigation of the inter-relations between socio-economic driving forces and the state of the environment. Results The presented results for the 25 EU countries focus on the following variables: unemployment, material extraction, energy supply and CO2 emissions. The lowest amount of unemployment is in the SEDG scenario, where it steadily decreases from 2005 to 2020. In BAMBU it falls to a level that is also below that of 2005. In GRAS, the number of unemployed people in 2020 is clearly over the value of 2005. The development of total material extraction from 2005 to 2020 is nearly stable in BAMBU, while it clearly increases in GRAS. Only in SEDG is there a reduction in resource use. None of the scenarios achieves a substantial reduction in energy use. However, the development of CO2 emissions shows a decoupling from energy supply. For BAMBU there is a slight decline in CO2 emissions over time, for GRAS they increase but with a slightly smaller growth rate than energy supply. In SEDG the emissions are reduced. The decoupling trends can be explained by a shift to more renewable energy sources in all scenarios, with the highest share in SEDG. Main conclusions The results indicate that a growth-oriented policy design, such as presented in the GRAS scenario, is not compatible with the conservation of biodiversity. Only in the SEDG scenario do the policy measures support the idea of a sustainable development, but in some respects they are still not ambitious enough. [ABSTRACT FROM AUTHOR]

This article analyses the development of integration policies concerning third country nationals at the level of the European Union (EU). Starting with the discovery of recent policy developments at the European level, including new European directives mainly granting social rights to non-EU citizens, the paper proceeds to examine the reasons that enabled this shift from the national to the European level of decision making. It concludes that integration policies have been created as a new EU policy field amidst the also fairly new policy field of immigration policies. In light of the theoretical concept of “organisational fields,” the interests and motives of the main actors involved in the emergence of this policy field are analysed. The research combines neo-functionalist and intergovernmentalist assumptions, and it results in the following conclusions: First, a European integration policy could only be established within the emerging field of immigration policies, which laid the groundwork for member state collaborations in this highly sensitive policy area. Secondly, the European Parliament, the Council of Europe, several non-governmental organisations and most notably the European Commission played an important role in promoting integration policies at the European level. Their engagement is interpreted as a necessary but not as a sufficient condition for the establishment of this policy field. Thirdly, these actors tried to strengthen the status of integration policies by emphasising the linkage between successful integration policies and economic and social cohesion. This semantic strategy, among other discussed reasons, facilitated the member states’ decision at the European summit in Tampere 1999 that all third country nationals shall be granted comparable rights to EU citizens.
