  1. 1. Soil Erosion estimation for the Göta Älv river using remote sensing, GIS and the Revised Universal Soil Loss Equation (RUSLE) model

    Magister-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Konstantinos Sourlamtas; [2019]
    Nyckelord :;

    Sammanfattning : According to previous studies, the study area of Göta Älv river has high risk of landslides along the river banks due to the water flow. Soil erosion can affect the increase of the landslides in an area with unstable soils caused by the increase rainfall. LÄS MER

    Sammanfattning : Sub-Saharan Africa suffers from land degradation, depletion of natural resources and rural poverty. In the Lake Victoria Basin, where large parts of the population are small scale farmers, people are facing such issues coupled with altered climatic conditions. LÄS MER

  4. 3. GIS-based time series study of soil erosion risk using the Revised Universal Soil Loss Equation (RUSLE) model in a micro-catchment on Mount Elgon, Uganda

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

    Författare :Boyi Jiang; [2013]
    Nyckelord :geomatics; Physical Geography and Ecosystem Analysis; time series; GIS; Revised Universal Soil Loss Equation RUSLE ; Uganda; soil erosion; Earth and Environmental Sciences;

    Sammanfattning : Land degradation has already been treated as one of the most serious problem all around the world. This study is a GIS-based time series study which devotes to calculate annual soil loss value, seek for soil erosion trends linked with precipitation and land use in Manafwa micro-catchment, Mount Elgon region, Uganda.

  5. 4. Soil physical properties and erosion risks at smallholder farms in Embu, Kenya

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

    Författare :Sara Rosén; [2009]
    Nyckelord :erosion; Kenya; soil physical properties;

    Sammanfattning : The soils ability to produce food is important in all parts of the world. The soils used for food production in Kenya are threatened by different factors, such as soil degradation due to erosion, lack of nutrients, and scarcity of water. LÄS MER

  7. 5. Soil erosion in northern Lao PDR : an evaluation of the RUSLE erosion model : a minor field study

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

    Författare :Wilhelm Dubber; Mari Hedbom; [2008]
    Nyckelord :soil erosion; southeast Asia; RUSLE erosion model; northern Lao PDR; physical geography; geography; Earth and Environmental Sciences;

    Sammanfattning : Jorderosion är ett stort problem på många platser på jorden. Ökad befolkning och brist på jordbruksmark leder till försämrad produktion och tvingar bönderna att öppna upp skogar, överbeta betesmarker, övergödsla och odla på branta sluttningar. När vegetationstäcket sedan är undanröjt är marken mer utsatt för regn. LÄS MER
