2. 1. Critical loads - assessment of uncertainty

   Author : Andreas Barkman; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landscape planning; regionalisation; forestry; BC Al; sensitivity analysis; risk assessment; Monte Carlo simulation; PROFILE; critical level; exceedance; Acidification; forest soil; policy; EMEP; GIS.; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Abstract : The effects of data uncertainty in applications of the critical loads concept were investigated on different spatial resolutions in Sweden and northern Czech Republic. Critical loads of acidity (CL) were calculated for Sweden using the biogeochemical model PROFILE. READ MORE

4. 2. Recovery from Acidification - Policy Oriented Dynamic Modeling

   Author : Liisa Fransson; Institutioner vid LTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi; Chemical technology and engineering; target loads; sea-salt episode; sulfate adsorption; SAFE; LRTAP; critical loads; integrated assessment;

   Abstract : Dynamic biogeochemistry models are important tools for determining the time-scales of recovery from acidification. In the review process of the 1999 UNECE LRTAP Gothenburg protocol, results from dynamic models will probably be included when determining further reductions of acidifying emissions. READ MORE

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

   Author : Lovisa Hagberg; Katarina Eckerberg; James Meadowcroft; Umeå universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. What Can Nature Withstand? : Science, Politics and Discourses in Transboundary Air Pollution Diplomacy

   Author : Karin Bäckstrand; Statsvetenskapliga institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political and administrative sciences; discourse analysis; constructivism; science–policy interface; critical loads; international environmental politics; transboundary air pollution; Environmental law; Statsvetenskap; förvaltningskunskap; Miljörätt;

   Abstract : Long-range transboundary air pollution generates pressing environmental problems such as the acidification of lakes and soils, forest decline and loss of biodiversity as well as threats to human health across Europe. The overall aim of this study is to explore the role of scientific expertise in environmental diplomacy by analyzing recent international agreements in the transboundary air pollution (LRTAP) regime.

7. 5. Dynamics of forest soil chemistry

   Author : Mattias Alveteg; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; critical loads; regional; recovery; acidification; modelling; SAFE; MAKEDEP; Kemiteknik och kemisk teknologi; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Abstract : Acidification caused by emissions of Nitrogen and Sulphur and associated adverse effects on forest ecosystems has been an issue on the political agenda for decades. Temporal aspects of soil acidification and/or recovery can be investigated using the soil chemistry model SAFE, a dynamic version of the steady-state model PROFILE used in critical loads assessment on the national level, e.
