  1. 1. Chronic kidney disease mortality in Costa Rica ; geographical distribution, spatial analysis and non-traditional risk factors

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

    Författare :Negin A Sanati; [2015]
    Nyckelord :chronic kidney disease; physical geography and ecosystem analysis; GIS; hot spot; heat exposure; farming; Medicine and Health Sciences;

    Sammanfattning : Central America in general and Costa Rica in particular have been facing with increasing number of Chronic Kidney Disease (CKD). Experts have recently (2013) recommended spatial analysis of the relevant data for better understanding of the situation. LÄS MER

  2. 2. Testing the robustness of the Plant Phenology Index to changes in temperature

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

    Författare :Iain Lednor; [2015]
    Nyckelord :NDVI; Plant Phenology Index; physical geography and ecosystem analysis; remote sensing; EVI2; Vegetation Index; temperature; phenology.; Earth and Environmental Sciences;

    Sammanfattning : Traditional vegetation indices have long encountered a problem of saturating at high biomass levels. A newly formulated vegetation index, the Plant Phenology Index (PPI), which has a near linear relationship with canopy green leaf area index (LAI) is tested in this study against temperature at 12 sites across Sweden.

  3. 3. Accuracy assessment in glacier change analysis

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

    Författare :Inese Linuza; [2014]
    Nyckelord :Physical Geography and Ecosystem analysis; GIS; accuracy assessment; glaciology; Digital Elevation Models DEMs ; interpolation; Earth and Environmental Sciences;

    Sammanfattning : This thesis assesses the accuracy of digital elevation models (DEM) generated from contour lines and LiDAR points (Light Detection and Ranging) employing several interpolation methods at different resolutions. The study area is Jostefonn glacier that is situated in Sogn og Fjordane county, Norway. LÄS MER

  4. 4. Spatiotemporal variability in methane emission from an Arctic fen over a growing season : dynamics and driving factors

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

    Författare :Kirstine Skov; [2014]
    Nyckelord :seasonal variability; Arctic wetlands; physical geography; methane emission; biological factors.; geography; ebullition; environmental factors; spatial variability; Earth and Environmental Sciences;

    Sammanfattning : Resume. Metanudledning fra Nordlige vådområder udgør en betydelig del af den naturlige udledning af metan, en potent drivhusgas. Både fysiske og biologiske faktorer influerer produktion, oxidation og transport af metan og dermed netto udledningen. Udledningen af metan fra Nordlige vådområder viser stor rumlig og tidslig variation. LÄS MER

  5. 5. Urban land-use planning using Geographical Information System and Analytical Hierarchy Process : case study Dhaka city

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

    Författare :Kazi Masel Ullah; [2014]
    Nyckelord :land-use planning; AHP; Physical Geography and Ecosystem analysis; GIS; urban planning; land suitability; Dhaka city; Earth and Environmental Sciences;

    Sammanfattning : Urban land-use planning, which is a useful tool for the sustainable development of a city, is a complex decision making process. However, the modern GIS technologies facilitate such complex jobs in two ways – (i) GIS allows to work with large numbr of datasets, (ii) a number of methods, techniques or models could be embeded in GIS for land-use suitability analysis.
