1. 11. Going Green : A Study of Public Procurement Regulation

   Författare :Lina Wedin Hansson; Rättssociologiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Norms; GreenPublic Procurement.; Legal Rationality; Sociology of Law; Regulation;

   Sammanfattning : In Sociology of Law the discussions about regulation have been extensive and the issue of public procurement is gaining momentum as its true financial value and potential to impact markets are realised. This thesis aims to look at the regulation of green public procurement (GPP) by analysing findings from an in-depth case study in a Swedish context, using interviews with procurement officers as well as analyses of court cases.

3. 12. Land-atmosphere exchange of carbon in a high-Arctic wet tundra ecosystem

   Författare :Torbern Tagesson; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon; methane; carbon dioxide; climate change; Arctic; NDVI; NDWI; micrometeorology; remote sensing; chamber; tundra;

   Sammanfattning : Arctic ecosystems play a key role in the terrestrial carbon (C) cycle, but spa-tially explicit data on the C exchange is scarce in these remote areas. The global warming is especially dominant in the Arctic, and these areas are vul-nerable to climate change. LÄS MER

4. 13. Green Public Procurement : Legal Instruments for Promoting Environmental Interests in the United States and European Union

   Författare :Jason J. Czarnezki; Jan Darpö; Roberto Caranta; Katerina Mitkidis; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental law; procurement law; green public procurement; sustainable public procurement; eco-labels; life-cycle costing; comparative law; Public Sector Directive 2014 24 EU; neoliberal regulation; sustainability; private environmental governance; public procurement; market participant exception; commerce clause; dormant commerce clause;

   Sammanfattning : While public environmental law, regulation and governance have paved the traditional road towards environmental and natural resource protection, the pathway has been expanded to include a broader orbit of interest areas and regulatory tools in an effort to achieve sustainability. Through the lens of comparative law and policy, this thesis evaluates one such expansion of environmental law—attempts to further environmental interests through public procurement in the European Union (EU) and United States (U.

5. 14. Carbon metabolism in clear-water and brown-water lakes

   Författare :Jenny Ask; Jan Karlsson; Mats Jansson; Rolf Vinebrooke; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; clear-water lakes; brown-water lakes; primary production; bacterial production; benthic; pelagic; net ecosystem production; allochthonous organic carbon; CO2; DOC; Physical geography; Naturgeografi; Freshwater ecology; Limnisk ekologi; limnologi; Limnology; naturgeografi; Physical Geography;

   Sammanfattning : The trophic state of lakes is commonly defined by the concentration of nutrients in the water column. High nutrient concentrations generate high phytoplankton production, and lakes with low nutrient concentrations are considered low-productive. LÄS MER

7. 15. Remote Sensing of Carbon Balance across Scandinavian Forests

   Författare :Pontus Olofsson; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forests; Natural science; Naturvetenskap; Carbon balance; Remote sensing;

   Sammanfattning : A methodology for estimating the carbon balance across Scandinavian forests using remote sensing is presented. By estimating the gross primary production (GPP) and the ecosystem respiration (ER), and thereby, the net ecosystem exchange (NEE), using parameters that are routinely retrieved from satellite, it is possible to implement an operational model for obtaining large scale NEE.
