  1. 6. Assessing Carbon Dioxide Removal methods amid uncertainty : soil carbon sequestration, biochar and harvested wood products as methods for climate change mitigation

    Författare :Alexander Olsson; Stefan Grönkvist; Mathias Fridahl; Anders Hansson; Lowe Börjeson; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Dioxide Removal CDR ; Negative Emissions Technologies NETs ; Soil Organic Carbon; Biochar; Harvested Wood Products HWP ; Socio-technical systems; Strategic Niche Management SNM ; Chemical Engineering; Kemiteknik;

    Sammanfattning : Measures to sequester carbon dioxide (CO2) away from the atmosphere have become increasingly important in the discussion of which methods humans can employ to limit global warming. These measures, which are broad and varied, fall under the umbrella of Carbon Dioxide Removal (CDR) methods. LÄS MER

  3. 7. The importance of tree cover for water resources in semiarid West Africa

    Författare :Aida Bargues Tobella; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The current paradigm in forest hydrology implies that an increase in tree cover always leads to reduced water yields as a result of increased interception and transpiration (ET) losses. This trade-off theory, in which more trees mean less water, has led to concerns that the establishment of trees in drylands may jeopardize scarce water resources. LÄS MER

  4. 8. Traps and transformations : Exploring the potential of water system innovations in dryland sub-Saharan Africa

    Författare :Elin Enfors; Line Gordon; Christian Valentin; Stockholms universitet; []
    Nyckelord :smallholder farming; water system innovations; agricultural droughts; multi-functional landscapes; development trajectories; uncertainty; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

    Sammanfattning : In semi-arid and dry sub-humid sub-Saharan Africa (SSA), high poverty levels and a heavy reliance on small-scale rainfed agriculture make rural livelihoods difficult. Upgrading current farming systems, in a way that safeguards productivity beyond field-scale, is urgent. LÄS MER
