  1. 31. Forestry Carbon Sequestration and Trading: a Case study of Mau Forest Complex in Kenya

    Magister-uppsats, Högskolan i Gävle/Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Författare :Kevine Okoth Otieno; [2015]
    Nyckelord :carbon; indices; NDVI; change detection; biomass; remote sensing;

    Sammanfattning : The global temperature is at an all-time high, the polar ice is melting, the sea levels are rising and the associated disasters are a time bomb. These variations in temperature are thought to trace roots to anthropogenic sources. LÄS MER

  3. 32. 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

  4. 33. Diamonds in the Rough : Remote predictive mapping using multispectral satellite imagery for kimberlite exploration on northeast Banks Island, NT

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Anne Farineau; [2015]
    Nyckelord :;

    Sammanfattning : This study demonstrates the use and limitations of Remote Predictive Mapping (RPM) as an aid to kimberlite exploration on northeast Banks Island, Northwest Territories, Canada. It focuses on the effectiveness of ASTER and Landsat 8 optical multi-spectral satellite imagery for discerning the spectral properties of different bedrock and surficial materials that outcrop or blanket the regional terrain.

  5. 34. Detecting changes in cropland extent: A case study within the Lake Chad Basin using classified remote sensing data

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Rebecka Jenryd; [2014]
    Nyckelord :Lake Chad; irrigation; cropland; classified remote sensing data; KYB; Chari-Logone; GLCC; MCD12Q1; Globcover; bi-temporal analysis; multi-temporal analysis; Technology and Engineering;

    Sammanfattning : Access to fresh water is essential for the lives of organisms and for human activities. However, with a growing population that strives after a higher standard of living, the pressure on already limited resources will rise. LÄS MER

  7. 35. The suitability of using Landsat TM-5 Images for estimating chromophoric dissolved organic matter in subarctic Lakes

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

    Författare :Julia Jakobsson; [2014]
    Nyckelord :CDOM; dissolved organic carbon; colored dissolved organic matter; Chromophoric; landsat thematic mapper 5; subarctic lakes; Stordalen; empirical algorithm.; Abisko; DOC; remote sensing; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Sammanfattning : Recent trends of permafrost thawing in the subarctic are expected to cause increased release of dissolved organic carbon (DOC) to inland waters, which might have cascading effects on downstream aquatic ecosystems and release of CO2 to the atmosphere. This study therefore aimed at evaluating the applicability of an empirical band ratio algorithm for estimating chromophoric dissolved organic matter (CDOM; a proxy for DOC) from the easily accessible satellite images Landsat TM-5, to counter the inaccessibility of the region in general.
