  1. 1. Tracing mangrove forest dynamics of Bangladesh using historical Landsat data

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

    Författare :Md Monirul Islam; [2017]
    Nyckelord :Bangladesh; Physical Geography and Ecosystem Analysis; Landsat; mangroves; change detection; time-series; NDVI; supervised classification; Earth and Environmental Sciences;

    Sammanfattning : Present, accurate, and reliable estimation of mangrove forests in Bangladesh is limited. Former estimation of mangroves extent and density has been more or less restricted to Sundarbans and do not represent the whole country. LÄS MER

  2. 2. Detecting clear-cut deforestation using Landsat data : a time series analysis of remote sensing data in Covasna County, Romania between 2005 and 2015

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

    Författare :Tudor Buhalau; [2016]
    Nyckelord :Landsat; BFAST; Covasna; Physical Geography and Ecosystem Analysis; deforestation; time series; NDVI; NDMI; Earth and Environmental Sciences;

    Sammanfattning : Forested areas represent a fundamental component of the environment. Deforestation and forest fragmentation represent a global issue mostly caused by human influence and Romania is not an exception. Nowadays forests cover approximately a third of Romania’s surface, meaning that the deforestation is a national issue. LÄS MER

  3. 3. Spatial assessment of NDVI as an indicator of desertification in Ethiopia using remote sensing and GIS

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

    Författare :Gezahagn Negash Seboka; [2016]
    Nyckelord :NDVI and Rainfall; land degradation; climate change; desertification; NOAA AVHRR; land cover; GIS; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

    Sammanfattning : Desertification is a serious environmental and socio-economic problem occurring at global, regional and local scale. According to Article 1(a) of the United Nations Convention to Combat Desertification (UNCCD), define the term “desertification” means “land degradation in arid, semi-arid and dry sub-humid (dry lands) areas resulting from various factors, including climatic variations and human activities”.

  4. 4. Reaching the 2014 UN New York Declaration on Forests Goals, using satellites to monitor global value chains

    Master-uppsats, Stockholms universitet/Kulturgeografiska institutionen

    Författare :Rickard Näsström; [2015]
    Nyckelord :Remote Sensing; CSR; Value chains; Deforestation NDVI; WICS.;

    Sammanfattning : This master thesis in geography investigates how remote sens- ing can be used in Transnational Corporations (TNC) global Corporate Social Responsibility (CSR) initiatives. The study aims to delineate an accurate method in remote sensing to be used to monitor deforestation in global value chains. LÄS MER

  5. 5. Investigation of deforestation in East Africa on regional scales

    Master-uppsats, Institutionen för naturgeografi och kvartärgeologi (INK)

    Författare :Yi-Hua Wu; [2011]
    Nyckelord :;

    Sammanfattning : Tropical forests contain abundant natural resources and play an important role in the balance of the ecosystems and environment. Depletion of forests could destroy habitats of endangered plants and animals and cause biodiversity loss. LÄS MER
