  1. 1. Livestock, feed production and land use – an environmental assessment

    Författare :Yaw Sasu-Boakye; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; partial equilibrium modelling; land use impacts; livestock production; soya beans; life cycle assessments; ecosystem services; protein feeds; feed substitution;

    Sammanfattning : The use of land for agriculture contributes substantially to today’s global environmental challenges such as climate change, water and land degradation and biodiversity loss. Today, about 38% of the ice-free land surface on earth is used as agricultural land, with about 75% of agricultural land used to produce feed for livestock. LÄS MER

  3. 2. Inferring Land Use from Remote Sensing Imagery : A context-based approach

    Författare :Michael Meinild Nielsen; Bo Malmberg; Anders Wästfelt; Douglas A. Stow; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; land use; remote sensing; urban remote sensing; image analysis; segmentation; spatial context; land cover; land cover configuration; farming types; bark beetle; dead trees; forest inventory; kulturgeografi; Human Geography;

    Sammanfattning : This doctoral thesis investigates the potential of classification methods based on spatial context to infer specific forms of land use from remote sensing data. The problem is that some types of land use are characterized by a complex configuration of land covers that traditional per-pixel based methods have problems classifying due to spectral heterogeneity.

  4. 3. Rooting for forest resilience : Implications of climate and land-use change on the tropical rainforests

    Författare :Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Axel Kleidon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; forest dynamics; human influence; land-use change; rainforest tipping; remote sensing; resilience; root zone storage capacity; tropical forests; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : Tropical rainforests in the Amazon and Congo River basins and their climate are mutually dependent. Evaporation from these forests help regulate the regional and global water cycle. Furthermore, these rainforests themselves depend on precipitation to sustain their structure and functions. LÄS MER

  5. 4. Road structures under climate and land use change : Bridging the gap between science and application

    Författare :Zahra Kalantari; Folkeson Lennart; Nachtnebel Hans-Peter; KTH; []
    Nyckelord :Adaptation; extreme rainfall events; runoff; land use; climate change; flood hazard; SRA - Transport; SRA - Transport; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Sammanfattning : Future changes in climate and land use are likely to affect catchment hydrological responses and consequently influence the amount of runoff reaching roads. Blockages and damage to under-dimensioned infrastructure can be extremely costly for the regions affected. LÄS MER

  7. 5. Allemansrätten och marknyttjande : Studier av ett rättsinstitut

    Författare :Åsa Åslund; Ingrid Arnesdotter; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; The right of public access; customary law; custom; land use; recreation.; Allemansrätt; sedvanerätt; sedvana; markanvändningsregler; marknyttjande; friluftsliv; topik; LAW JURISPRUDENCE; RÄTTSVETENSKAP JURIDIK;

    Sammanfattning : The topic studied in this thesis is the right of public access as a legal institution. In that connection, several questions which are different from each other are raised. The thesis focuses to a great extent on the interaction between questions of a practical-legal nature and those whose character is more connected to legal theory. LÄS MER
