  2. 1. Remote Sensing of Woodland Structure and Composition in the Sudano-Sahelian zone : Application of WorldView-2 and Landsat 8

    Author : Martin Karlson; Madelene Ostwald; Tina Schmid Neset; Heather Reese; Frédéric Achard Forobs; Linköpings universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Remote sensing; Sudano-Sahel; woodland; agroforestry; WorldView-2; Landsat 8; tree attributes; tree canopy cover; aboveground biomass; Random Forest; Fjärranalys; Sudano-Sahel; woodland; WorldView-2; Landsat 8; trädattribut; trädtäcke; biomassa; Random Forest;

    Abstract : Woodlands constitute the subsistence base of the majority of people in the Sudano-Sahelian zone (SSZ), but low availability of in situ data on vegetation structure and composition hampers research and monitoring. This thesis explores the utility of remote sensing for mapping and analysing vegetation, primarily trees, in the SSZ. READ MORE

    Abstract : Urbanization is one of the great challenges in the 21st century. Despite being an engine for the global economy, urban areas consume 78% of World's energy and emit more than 60% of greenhouse gas emission. Sub-SaharanAfrican cities, e.g. READ MORE

  5. 3. Monitoring biodiversity in cultural landscapes: development of remote sensing- and GIS-based methods

    Author : Jonas Dalmayne; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : Remote sensing; statistical modeling; spatial scales; partial least squares; support vector machines; grazed grasslands; LULC; HySpex; Worldview-2; Landsat; heterogeneity; landscape complexity; plant species diversity;

    Abstract : In this thesis, I explore the relationships between structural and compositional landscape properties, and species diversity, using remotely sensed data on a variety of spatial scales. The thesis shows that increased landscape heterogeneity, measured using environmental and spectral variables that were used both separately and combined, is generally positively related to plant species richness.

  6. 4. Hyperspectral and multispectral remote sensing for mapping grassland vegetation

    Author : Thomas Möckel; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant diversity Partial least squares Ellenberg indicators Vegetation index Heterogeneity;

    Abstract : As a consequence of agricultural intensification, large areas of species-rich grasslands have been lost and farmland biodiversity has declined. Previous studies have shown that the continuity of grazing management can have a significant influence on the environmental conditions and the levels of plant species diversity in grassland habitats.

    Abstract : As of 2018, 55% of the world population resides in urban areas. This proportion is projected to increase to 68% by 2050 (United Nations 2018). The Stockholm region is no exception to this urbanizing trend: the population of Stockholm City has risen by 28% since the year 2000. READ MORE
