  1. 21. Cultivation potential in Hambantota district, Sri Lanka : a minor field study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Per Schubert; [2004]
    Keywords : naturgeografi; climatology; agricultural production; crop yield; physical geography; point system; geomorphology; cartography; pedology; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : Populärvetenskaplig sammanfattning: För att öka tillgången på mat och att generera arbeten och inkomster är det angeläget för utvecklingsländer att öka produktionen inom jordbruket. En förutsättning för detta är att eliminera produktionshinder genom att dels förbättra jordbruksmetoder, dels identifiera olika områden som är lämpliga för olika typer av jordbruk. READ MORE

  3. 22. Analysing environmental change in semi-arid areas in Kordofan, Sudan

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tobias Hinderson; [2004]
    Keywords : naurgeografi; climatology; cartography; desertification; vegetation pattern; physical geography; Sahara; pedology; geomorphology; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : Forskning har visat på en trendökning i NOAA NDVI för Sahelområdet under perioden 1982-1999. Dessa observationer kan indikera att vegetationsmängden i området är ökande. Förändringen kan tolkas som en återhämtning från torkan som drabbade området under 1970- och 1980-talen. READ MORE

  4. 23. Investigating vegetation changes in the African Sahel 1982-2002 : a comparative analysis using Landsat, MODIS and AVHRR remote sensing data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Martin Sjöström; [2004]
    Keywords : marklära; desertification; semi-arid; Sahara; physical geography; geomorphology; pedology; cartography; climatology; geomorfologi; naturgeografi; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : There has been much debate concerning the concept of degradation and desertification in semi-arid lands, in particular semi-arid Sub-Saharan Africa, during the last two decades. However, recent findings suggest a consistent trend of increasing satellite-derived vegetation greenness in much of the African Sahel as interpreted from Pathfinder Advanced Very High Resolution Radiometer (AVHRR) Normalized Difference Vegetation Index (NDVI) data for the period 1982-1999.

  5. 24. The dynamics of non-methane hydrocarbons and other trace gas fluxes at a subarctic mire in northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Kristina Bäckstrand; [2004]
    Keywords : geomorfologi; naturgeografi; climatology; cartography; climate change; carbon cycle; physical geography; nodelling; pedology; geomorphology; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : In the context of climate change, it is important to understand how the terrestrial carbon cycle is interacting with the anthropogenic increase in atmospheric carbon dioxide (CO2) concentration. Boreal and subarctic regions in the northern hemisphere are great carbon pools, as well as they are subject to predicted warming. READ MORE

  6. 25. Forests acting as a carbon source : analysis of two possible causes for Norunda forest site

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Stefano Materia; [2004]
    Keywords : geomorfologi; naturgeografi; climatology; cartography; boreal forests; CO2 uptake; physical geography; drainage; pedology; geomorphology; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Abstract : Only 40% of the total CO2 emitted by human activities and natural sources remain in the atmosphere, since the rest is taken up by plants and oceans. In particular temperate and boreal forests are usually significant sinks of carbon, even if they are very susceptible ecosystems and they might turn into sources in consequence of the predicted temperature increase.
