Romanian street beggars in Stockholm. A conflict between global city aspirations and informal livelihoods.

This thesis is looking into the issue of Romanian street beggars in Stockholm, Sweden. In the last couple of years there was an increase in the number of beggars in the Swedish capital, while most of them seem to come from Romania. This lead quickly to a national debate. The aim of the paper is to shed some light on this issue and see why it is a problem and for whom, looking at three main stakeholders: the state, the activists and the beggars. The theoretical framework for this project is mainly based on the concept of the conflict of rationalities, with Stockholm as an aspiring global city and those which are begging as livelihood strategy. The data is collected mainly through semi-structured interviews, informal interviews and personal observations. Also, the literature review provides context and brings similar examples for a better grasp of the situation in Sweden. The results show that Stockholm sends a branded image of itself to the world, while the new type of migrant is in conflict with this view. The activists try to make the life better for the beggars which are virtually not doing anything illegal. The Swedish state opened discussions with the Romanian state, but did nothing to integrate the newcomers. In this case, the beggars share similar experience in the city.

Modeling long-term variability and change of soil moisture and groundwater level - from catchment to global scale

The water stored in and flowing through the subsurface is fundamental for sustaining human activities and needs, feeding water and its constituents to surface water bodies and supporting the functioning of their ecosystems. Quantifying the changes that affect the subsurface water is crucial for our understanding of its dynamics and changes driven by climate change and other changes in the landscape, such as in land-use and water-use. It is inherently difficult to directly measure soil moisture and groundwater levels over large spatial scales and long times. Models are therefore needed to capture the soil moisture and groundwater level dynamics over such large spatiotemporal scales. This thesis develops a modeling framework that allows for long-term catchment-scale screening of soil moisture and groundwater level changes. The novelty in this development resides in an explicit link drawn between catchment-scale hydroclimatic and soil hydraulics conditions, using observed runoff data as an approximation of soil water flux and accounting for the effects of snow storage-melting dynamics on that flux. Both past and future relative changes can be assessed by use of this modeling framework, with future change projections based on common climate model outputs. By direct model-observation comparison, the thesis shows that the developed modeling framework can reproduce the temporal variability of large-scale changes in soil water storage, as obtained from the GRACE satellite product, for most of 25 large study catchments around the world. Also compared with locally measured soil water content and groundwater level in 10 U.S. catchments, the modeling approach can reasonably well reproduce relative seasonal fluctuations around long-term average values. The developed modeling framework is further used to project soil moisture changes due to expected future climate change for 81 catchments around the world. The future soil moisture changes depend on the considered radiative forcing scenario (RCP) but are overall large for the occurrence frequency of dry and wet events and the inter-annual variability of seasonal soil moisture. These changes tend to be higher for the dry events and the dry season, respectively, than for the corresponding wet quantities, indicating increased drought risk for some parts of the world.
