  1. 1. Impacts of climate change on surface hydrology in the source region of the Yellow River

    Författare :Feifei Yuan; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source region of the Yellow River; climate change; summer precipitation; ENSO; teleconnection pattern; sea surface temperature; Xinanjiang model; Rainfall-Runoff process;

    Sammanfattning : The source region of the Yellow River contributes about 35% of the total water yield in the Yellow River basin playing an important role for meeting the downstream water resources requirements. The declining water availability caused by climate change in the source region of the Yellow River is expected to have severe repercussions for the 110 million basin inhabitants in terms of water resources affecting agricultural productivity, municipal, and industrial water supply.

  2. 2. Primary Production in African Drylands : Quantifying Supply and Demand Using Earth Observation and Socio-ecological Data

    Detta är en avhandling från Lund University, Faculty of Science, Department of Physical Geography and Ecosystem Science

    Författare :Abdulhakim Abdi; [2017-02]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Net Primary Production NPP ; Africa; Drylands; Coupled Human and Natural Systems; Human-Environment Relations; Food; Fuel; Feed; Earth Observation; Remote Sensing; Biomass; Carbon; Supply and Demand;

    Sammanfattning : The human-environment connection in the mostly rural drylands of sub-Saharan Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. LÄS MER

  3. 3. Causal links of past climate change in Coupled Model Intercomparison Project Phase 5 climate models

    Detta är en avhandling från Lund University, Faculty of Science, Department of Geology, Quaternary Sciences

    Författare :Thanh Le; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solar forcing; volcanic forcing; greenhouse gases radiative forcing; Granger causality; near-surface air temperature; ENSO; IOD; CMIP5; North Atlantic;

    Sammanfattning : The climate system is influenced by various external forcings (e.g. volcanic forcing, solar forcing and change of greenhouse gas concentrations) and its own internal climate variability. LÄS MER

  4. 4. Terrestrial Ecosystem Interactions with Global Climate and Socio-Economics

    Detta är en avhandling från Department of Physical Geography and Ecosystem Science, Lund University

    Författare :Anders Ahlström; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The global terrestrial carbon cycle plays a pivotal role in regulating the atmospheric composition of greenhouse gases. Currently it is responsible for removing 25-30% of our emissions every year, an important ecosystem service that may not persist in the long term. LÄS MER

  5. 5. Climate Change Effects on Rainfall and Management of Urban Flooding

    Detta är en avhandling från Department of Physical Geography and Ecosystem Science, Lund University

    Författare :Arun Rana; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Climate Change; Extreme Events; Intensive Rainfall; Urban Drainage; Intensity-Duration-Frequency; Statistical analysis; Flood Management;

    Sammanfattning : Flooding in urban basins is intensifying due to increasing urbanization and climate change and variability. This thesis presents how the effects of climate change and high-intensive rainfall on the urban drainage system and management of flooding in urban areas of were studied in Mumbai, India and Southern Sweden, including Skåne and Gothenburg.
