  3. 2. Influence of structural complexity of the Rumperöd forest on evapotranspiration

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Madeleine Durdek; [2023]
    Nyckelord :Forest structural complexity; evapotranspiration; vapour pressure deficit; eddy covariance; Earth and Environmental Sciences;

    Sammanfattning : The influence of Forest Structural Complexity (FSC) on evapotranspiration (ET) was investigated in a mixed forest of Southern Sweden where micrometeorological Eddy Covariance (EC) measurements were conducted for the years 2015 to 2022. For each year, the top 25% of Vapour Pressure Deficit (VPD) were selected to emphasize the response of ET to the driest atmospheric conditions. LÄS MER

  7. 5. Long Run Emission-Growth Nexus: An Empirical Evidence

    Master-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Champa Bati Dutta; [2014]
    Nyckelord :CO2 Emission; economic growth; Granger causality; substitution; Business and Economics;

    Sammanfattning : This study presents an empirical investigation of i) testing the Granger Causality between economic growth and aggregated carbon dioxide (CO2) emission; and economic growth and disaggregated CO2 emission from burning fossil fuel coal, oil and natural gas respectively; ii) the potential impact on economic growth if countries substitute CO2 emission from dirty energy, coal, by emission from relatively cleaner energy oil and natural gas. I undertake panel analysis of 30 countries and separate time series analysis for China, United States and United Kingdom during 1960-2010 sample years. LÄS MER
