  1. 6. Advancing Nexus Approaches: insights from practice in support of their operationalisation

    Författare :Eunice Pereira Ramos; Mark Howells; Francesco Gardumi; Vignesh Sridharan; Hans-Holger Rogner; Declan Conway; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nexus; Nexus approach; integrated resource assessments; CLEWs; integrated assessment modelling; knowledge transfer; sustainable development; Nexus; Nexus approach; integrerad resursbedömningar; CLEWs; integrerad bedömningsmodellering; kunskapsöverföring; hållbar utveckling; Energy Technology; Energiteknik;

    Sammanfattning : The last decade has seen the emergence of a new research theme - the study of the resources Nexus. The “Nexus” refers to considering the functioning of several systems simultaneously, as opposed to one, as the object of research. This perspective reasons that coherent decision-making needs to consider systems' interconnectedness. LÄS MER

  3. 7. Where have all the forests gone? Quantifying pantropical deforestation drivers

    Författare :Florence Pendrill; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Carbon footprints; International trade; Deforestation; Consumption-based accounting; Forest transitions; Telecoupling; Agriculture; Land use change; Carbon emissions; Land system science;

    Sammanfattning : Deforestation across the tropics continues to be a major source of greenhouse gas emissions and the largest threat to biodiversity on land. With strengthened commitments to reduce deforestation from countries and companies alike, it is crucial that renewed investments for reducing deforestation be guided by a sound understanding of what drives deforestation.

  4. 8. Recycling Filter Substrates used for Phosphorus Removal from Wastewater as Soil Amendments

    Författare :Victor Cucarella Cabañas; Gunno Renman; Greg Morrison; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Compact filter; Filtra P; Phosphorus recycling; Polonite; Soil amendment; Sorption isotherms; Soil science; Markvetenskap; Solution chemistry; Lösningskemi; Agricultural engineering; Jordbruksteknik; Water engineering; Vattenteknik; Environmental chemistry; Miljökemi;

    Sammanfattning : This thesis studied the viability of recycling filter substrates as soil amendments after being used in on-site systems for phosphorus (P) removal from wastewater. Focus was put on the materials Filtra P and Polonite, which are commercial products used in compact filters in Sweden. LÄS MER

  5. 9. Model-Based Stem Volume Retrieval and Windthrow Detection using CARABAS and P-band SAR

    Författare :Klas Folkesson; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CARABAS; remote sensing; forest monitoring; model-based stem volume retrieval; image segmentation; synthetic aperture radar SAR ; P-band; windthrow detection;

    Sammanfattning : Radar remote sensing is an efficient method for monitoring forests over large areas. Radar waves transmitted from a system carried by a satellite or an aircraft interact with trees on the ground, and the reflected waves are used to form images which are independent of weather and light conditions.

  7. 10. 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.
