Tidskriftsartikel (refereegranskat)abstract
- It is commonly assumed that European integration empowers prime ministers at the expense of cabinet ministers and parliamentary actors. This article follows the suggestion that an increase in cabinet reshuffles indicates power shifts in favour of the PM, and studies reshuffles in two countries that have been involved very differently in the process of European integration, Germany and Sweden. It hypothesises that if European integration empowers the PM, the PM will employ cabinet reshuffles more often. By implication, as integration increases, (1) ministerial reshuffles should become more frequent, and (2) political insiders and ministers holding important portfolios should be more likely to be dismissed. The results found in an event history analysis show that EU integration leads to an increase of turnover when looking at Swedish post-war cabinets, whereas no such effect is found for German cabinets. These results are in line with the idea that a differential impact of Europe on intra-executive relations should be expected.

Forskningsöversikt (refereegranskat)abstract
- To address the challenges of biodiversity conservation and commodity production, a framework has been proposed that distinguishes between the integration (land sharing) and separation (land sparing) of conservation and production. Controversy has arisen around this framework partly because many scholars have focused specifically on food production rather than more encompassing notions such as land scarcity or food security. Controversy further surrounds the practical value of partial trade-off analyses, the ways in which biodiversity should be quantified, and a series of scale effects that are not readily accounted for. We see key priorities for the future in (1) addressing these issues when using the existing framework, and (2) developing alternative, holistic ways to conceptualise challenges related to food, biodiversity, and land scarcity.

Managing for biodiversity and ecosystem services in a context of farmland abandonment
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In agricultural landscapes around the world, intensification of production and land abandonment are the two main trends impacting biodiversity and ecosystem services. Intensified agriculture is mostly seen as negative for biodiversity but effects of abandonment are controversial among scientists and practitioners. While abandonment can be detrimental to biodiversity in non-intensive farming systems, it can also provide an opportunity for regeneration of natural habitats. This thesis examines effects of different management options on biodiversity along an abandonment gradient from farmland to forest. It combines insights from a local case study in NW Portugal with an inter-regional meta-analysis on the effects of land-use change on response diversity, and a global meta-analysis on how impacts of abandonment on biodiversity are reported in scientific studies. Effects of abandonment were assessed for species richness and functional diversity for multiple taxa, and for the provision of multiple ecosystem services.At the global scale, abandonment impacts on biodiversity were reported in contrasting ways across world regions, and this was influenced by conservation views focused on pre vs. post abandonment conditions. In the study area, intermediate farming intensity, compared to abandoned forest habitats, generated higher plant richness at small scales and when post-abandonment forest was highly fragmented. In contrast, at larger scales, both farmland and forest had high species and functional diversity of plants and birds, while moths were more diverse in forests. All land uses provided multiple ecosystem services, but while provisioning services were highest in farmland, forests benefited regulating services, a difference not reflected in species richness distribution. In contrast to current European policies, abandonment was not found to be disadvantageous to biodiversity, except for species richness at very small scales. Thus, both farming and post-abandonment succession can generate high value ecosystems. In order to sustainably manage abandoned lands, farmland abandonment needs to be analyzed in a broader perspective, combining different types of indicators, from species to ecosystem services, and avoiding pre-conceived ideas on conservation, not always beneficial to the sustainable management of these landscapes.
