  1. 6. Brazilian land use policies and the development of ecosystem services

    Författare :Flavio L. M. Freitas; Ulla Mörtberg; Gerd Sparovek; Martin Persson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brazil; Land use policy; Forest protection; Ecosystem services; Biodiversity; Offsetting of legal reserves; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Concerns related to global environmental changes due to land use changes have been driving international communities towards more sustainable land use systems. Brazil is a country of global strategic importance in this matter considering that it is the nation with the largest extension of preserved tropical native vegetation, recognised for its ecosystem services and high and unique biodiversity.

  3. 7. Assessing reactive nitrogen flows in European agricultural systems

    Författare :Rasmus Einarsson; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; food; nitrogen indicator; nitrogen budget; nitrogen; agriculture; nitrogen footprint; uncertainties;

    Sammanfattning : In most ecosystems, nitrogen is a scarce and growth-limiting nutrient. Natural and anthropogenic processes convert unreactive atmospheric dinitrogen (N2) into reactive, bioavailable, nitrogen. LÄS MER

  4. 8. How municipalities can work with digitalisation for environmental aims

    Författare :Tina Ringenson; Mattias Höjer; Jenny Palm; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainability; municipalities; environmental aims; environmental goals; smart city; smart sustainable city; digitalisation; ICT4S;

    Sammanfattning : Humanity is facing big environmental challenges. Apart from the climate changes, there is also an ongoing depletion of the natural resources necessary for our survival in general, and for highly electronics-dependant lifestyles especially. At the same time, both urbanisation and digitalisation are progressing at a rapid pace. LÄS MER

  5. 9. Taking stock of large-scale lithium-ion battery production using life cycle assessment

    Författare :Mudit Chordia; Chalmers tekniska högskola; []
