1. 1. Timber as a forest-risk commodity: embodied socio-ecological impacts in the Brazilian supply chain

   Författare :Caroline Sartorato Silva Franca; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Environmentally-extended input-output model; Land use; Supply chain traceability; Forest frontiers; Sustainable Forest Management SFM ; Forest degradation; Illegal logging;

   Sammanfattning : The continued loss and degradation of forest resources is one of the largest sustainability challenges of our time. The past decades rise in global demand for agricultural and forest commodities have created unparalleled pressure on the natural resources, leading to forest destruction and associated loss in carbon stocks, invaluable biodiversity, ecosystems services, livelihoods.

3. 2. 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.

4. 3. Barriers and bridges for intensified wood production and biodiversity conservation in NW Russia's boreal forest

   Författare :Vladimir Naumov; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Wood production and biodiversity conservation are two key objectives of sustainable forest management policy. These goals are rival and, therefore, hard to achieve at the same time and space. LÄS MER

5. 4. Climate impact of the sustainable use of forest biomass in energy and material system : a life cycle perspective

   Författare :Sylvia Haus; Johan Bergh; Bishnu Chandra Poudel; Krushna Mahapatra; Göran Berndes; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest residues; fossil fuel substitution; forest management; radiative forcing; land use change; climate change; bioenergy; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology; Byggteknik; Civil engineering;

   Sammanfattning : Human society releases greenhouse gas emissions to the atmosphere while providing housing, heat, mobility and industrial production. Man-made greenhouse gas emissions are the main causes of climate change, coming mainly from burning fossil fuels and land-use changes. LÄS MER

7. 5. Effects of forest management on greenhouse gas fluxes in a boreal forest

   Författare :Patrik Vestin; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :Forest management; Greenhouse gas fluxes; Clear-cutting; Thinning; Stump harvesting; Selective cutting; Eddy-covariance; Flux-gradient; Greenhouse gas budgets; CO2; CH4; N2O;

   Sammanfattning : Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies.
