1. 11. Finding a place for green politics : political space-time, globalisation and new environmental policy concepts

   Författare :Lovisa Hagberg; Katarina Eckerberg; James Meadowcroft; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political science; space-time; political time; bioregionalism; green political theory; place; river basin management; critical loads; ‘think global; act local’; globalisation; Statsvetenskap; Political science; Statsvetenskap; statskunskap; political science;

   Sammanfattning : The overarching aim of this dissertation is to rethink green ideas for change in political space-time against the background of globalisation. It is based on two avenues of investigation. First, green ideas are contrasted with the analyses of current changes in political space-time found in the globalisation literature. LÄS MER

3. 12. METHODS FOR TRANSBOUNDARY WATER RESOURCES MANAGEMENT IN WATER STRESSED REGIONS – CASE STUDY: SOUTHERN AFRICA

   Författare :Dinis Juizo; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; river basin simulation; water quality monitoring; stakeholders involvement; Southern Africa; South Africa; Mozambique; transboundary water systems; Swaziland;

   Sammanfattning : Water resources management in water scarce regions like the Southern Africa Development Community (SADC) is challenging with both large hydro-climatic-induced scarcity and the considerable inter-annual fluctuations at the centre of the allocation problem. Water must be allocated both in time and space using acceptable criteria and most importantly, all stakeholders must adhere to the decisions imposed by water sharing agreements. LÄS MER

4. 13. Environmental Sustainability of Water Projects

   Författare :Cecilia Tortajada; KTH; []
   Nyckelord :environmental sustainability; water projects; river basin management; Turkey; Latin America;

   Sammanfattning : The thesis focuses on the environmental sustainability ofwater projects. The concept is analysed from the theoreticaland the implementation viewpoints The evolution of the conceptof sustainable development is presented, with an in-depthdiscussion on the present status of the environmentalsustainability of water projects.

5. 14. Long-term development, modeling and management of nutrient loading to inland and coastal waters

   Författare :Amelie Darracq; Georgia Destouni; Andrea Rinaldo; Stockholms universitet; []
   Nyckelord :Nutrients; catchments; environmental management; climate change; population and lifestyle development; subsurface-surface water interactions; long-term simulations; nutrient retention; modeling; hydrology; transport processes; biogeochemistry; scaling; transport and reaction rates; Physical Geography; geografi med naturgeografisk inriktning;

   Sammanfattning : Environmental and water system protection and restoration require accurate knowledge and quantification of waterborne pollutant transport, retention-release and transformation processes taking place in the subsurface, river, lake and sea water systems, and at the interfaces between these systems. This thesis investigates the importance of spatial model resolution for such quantification and the possible long-term nutrient load development under different human perturbations and nutrient source management scenarios in the Swedish Norrström drainage basin, based on simulations with the GIS-based dynamic nutrient transport-attenuation model POLFLOW.

7. 15. Present and future precipitation variations in the source region of the Yangtze River, China

   Författare :Yiheng Du; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Precipitation; water balance; ENSO; PDO; Yangtze River; Tibet Plateau; future projections;

   Sammanfattning : The source region of the Yangtze River (SRYR), the origin of the longest river in China, is an area with high-mountains and river ecotones that face considerable challenges under climate change. Precipitation is fundamental for sustainable ecosystems in this area and for the downstream water supplies. LÄS MER
