  1. 1. Land Use, Freshwater Flows and Ecosystem Services in an Era of Global Change

    Författare :Line Gordon; Carl Folke; David Molden; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; freshwater; green water; ecosystem services; integrated water resources management; food production; land use and land cover change; vulnerability; resilience; hydrological cycle; global change; Australia; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The purpose of this thesis is to analyse interactions between freshwater flows, terrestrial ecosystems and human well-being. Freshwater management and policy has mainly focused on the liquid water part (surface and ground water run off) of the hydrological cycle including aquatic ecosystems. LÄS MER

  3. 2. Tracing water transport pathways in the coupled ocean-atmosphere system

    Författare :Dipanjan Dey; Kristofer Döös; Aitor Aldama Campino; David Ferreira; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrological cycle; inter-ocean atmospheric water transport; water-mass conservation; atmospheric water trajectories; overturning water-mass stream functions; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : Water is the most precious substance on the Earth and thus it is important to know how it moves around and is recycled.This knowledge will be useful to formulate educated future strategies about water usage in society and also to understand the near-surface salinity contrasts in the world ocean.

  4. 3. The interplay between atmosphere, hydrology and land use by environmental modelling

    Författare :Fabio Pereira; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Land use changes; expansion of sugarcane; hydrological cycle; coupled models;

    Sammanfattning : Interactions between land surface and atmosphere induced by human activities and natural environmental dynamics act on a time scale that varies from seconds to millions of years. It is by exchanging heat, water, energy and carbon that land surface and atmospheric processes are closely interrelated and influence each other in reciprocal ways. LÄS MER

  5. 4. The role of the hydrological cycle in forest ecosystems : flow path, nutrient cycling and water-carbon interaction

    Författare :Yanzi Yan; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flow path; DOC concentration; groundwater; photosynthesis; Amazon rainforest; catchment geomorphology;

    Sammanfattning : Forest ecosystems, covering over a third of land on the Earth, play a significant role in the global hydrological cycle, and influence soil erosion and climate change. However, the distribution, movements, quality of water, and hydrological processes in forested ecosystems are not well understood yet. LÄS MER

  7. 5. Bearing the brunt of warming: Interactions between carbon and hydrology in northern Sweden

    Författare :Pearl MZOBE; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissoved organic carbon DOC ; carbon flux; permafrost thaw; hydrological connectivity; GIS analysis;

    Sammanfattning : Climate modelling studies indicate that subarctic ecosystems are predicted to show some of the earliest responses to climate change. The predicted temperature and precipitation changes have implications for the carbon biogeochemical cycle with ancillary effects in permafrost soils, vegetation, and stream networks. LÄS MER
