  1. 1. NDVI time series analysis for desert locust outbreak detection and quantification analysis of its impact on vegetation productivity of Sahel

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

    Författare :Evangelos Oikonomopoulos; [2020]
    Nyckelord :Physical Geography and Ecosystem Analysis; Primary Productivity; Desert Locust; NDVI; Time Series Analysis; Outbreak Detection; Food Security; Sahel; Insect Disturbances; GEM; Earth and Environmental Sciences;

    Sammanfattning : It has been shown that the semi-arid environment of the Sahelian belt plays an important role in the global carbon uptake as the fluctuation of its primary productivity can be determinant for the global carbon uptake. The insect Schistocerca gregaria commonly known as the desert locust is a disturbance factor that can affect the vegetation productivity for consecutive seasons. LÄS MER

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

    Författare :Ashish Vivekar; [2020]
    Nyckelord :Physical Geography and Ecosystem analysis; Multispectral Sensor; Radiometric Correction; Reflection calibration; Phenology; GEM; Earth and Environmental Sciences;

    Sammanfattning : Adaptation of modern Unmanned Aerial Vehicle (UAV) and multispectral sensor technology in agriculture can enhance the capacity to accurately monitor crops. But these technologies come with its own set of challenges. LÄS MER

  3. 3. Analysis of the US procedure for the fuel consumption and greenhouse gases certification of heavy duty vehicles

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Paolo Enrico Viotti; [2019]
    Nyckelord :;

    Sammanfattning : The vehicle sector is facing the biggest revolution of the last 70 years, whose main target is the depletion of emission and a steady decrease of fuel consumption. The focus in this report is the Green House Gas Emissions model (GEM) developed by the United States Environmental Protection Agency (EPA). LÄS MER

  4. 4. Conflict, narratives, and forest fires in eastern Turkey : a quantitative perspective with remote sensing and GIS

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

    Författare :Aiman Shahpurwala; [2019]
    Nyckelord :geography; burned area; Turkey; warfare ecology; spatial analysis; GEM; Earth and Environmental Sciences;

    Sammanfattning : Within Turkey, claims of an increasing number of forest fires ignited by the Turkish military to ‘strategically degrade the environment’ broke out after the Turkish-Kurdish peace process ended in 2015. These claims are built on little evidence, and fire occurrences are not well documented. LÄS MER

  5. 5. The never ever perfect encyclopedia : an ethnographic analysis of participation in Wikipedia

    Master-uppsats, Lunds universitet/Medie- och kommunikationsvetenskap

    Författare :Xiaotong Shen; [2019]
    Nyckelord :participation; deliberative discussion; governance; public sphere; civic cultures; online collaboration; online community; netnography; wikis; Wikipedia; Social Sciences;

    Sammanfattning : Wikipedia represents ‘the sum of all human knowledge’ and is becoming the authoritative source on the Internet. As a collective work, how exactly are articles created by editors? The aim of the study is to seek the answer by use of participation theory. LÄS MER
