  1. 1. Cropland and tree cover mapping using Sentinel-2 data in an agroforestry landscape, Burkina Faso

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Ntandokazi Masimula; [2020-06-29]
    Nyckelord :Sentinel-2; Cropland mask; Tree cover estimation; Burkina Faso; Agroforestry; Random Forest;

    Sammanfattning : Sentinel-2, with high spatial resolution bands and increased number of spectral channels,has provided increased capabilities for vegetation mapping. Cropland masks withinheterogeneous areas such as the Sudano-Sahel zone have become useful for monitoringlandscapes. LÄS MER

  2. 2. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya

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

    Författare :Malin Ahlbäck; [2020]
    Nyckelord :Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

    Sammanfattning : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. LÄS MER

  3. 3. Soil organic carbon prediction using Sentinel-2 data and the LUCAS topsoil database

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

    Författare :Philipp Hansen; [2020]
    Nyckelord :Sentinel-2 LUCAS topsoil database Soil organic carbon mapping Multispectral data; Earth and Environmental Sciences;

    Sammanfattning : Its carbon sink potential as well as soil fertility benefits make organic carbon a soil variable for which reliable quantification methods are sought. This thesis work aims at investigating the possibility of adapting a large soil spectral library to build models for SOC predictions with remotely sensed, multispectral data. LÄS MER

  4. 4. Kadmium i grundvattnet i området kring Rörums Fur

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Anita Bauer-Lindgren; [2020]
    Nyckelord :groundwater; cadmium; Cambrian sandstone; alum shale; Sweden; Earth and Environmental Sciences;

    Sammanfattning : Cadmium poses a threat to both human health and the environment. In this study, cadmium levels in groundwater in the area around Rörums Fur in the municipality of Simrishamn, Sweden, and their potential sources were mapped, with the aim of getting an overview of the cadmium situation in the area.

  5. 5. Effects of afforestation and crop systems on the water balance in the highlands of Ethiopia

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Rebecca Naomi Ter Borg; [2020]
    Nyckelord :Acacia decurrens; landscape water balance; sediment yield; soil and water conservation; SWAT modelling; water balance partitioning;

    Sammanfattning : In the Upper Blue Nile Basin land use is rapidly changing due to agricultural development and intensification with potential effects on the water availability both up- and downstream. This study is aimed to explore the impact of agricultural land use change on a landscape water balance. LÄS MER
