  1. 1. Assessing the Impacts of Climate Change and Water Scarcity on Agricultural Practices in Kenya -Implications for Adaptation Strategies

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

    Författare :Sanjina Rahi Oishee; [2023]
    Nyckelord :Climate Change; Agriculture; Temperature; Precipitation; Water Scarcity; Agro-Climatic Zone; Earth and Environmental Sciences;

    Sammanfattning : Like other African countries, Kenya’ economy and food security is heavily dependent on agriculture. Climate change has led to variability in temperature and precipitation, and extreme weather events such as droughts and floods, all of which can significantly impact crop productivity and food security in the long-term.

  3. 2. Spatio-temporal analysis of groundwater-dependent precipitation based on Lagrangian moisture tracking

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Daowei Li; [2022]
    Nyckelord :Groundwater abstraction; groundwater dependent precipitation; ERA5 precipitation; Utrack; Lagrangian model.;

    Sammanfattning : Groundwater abstraction for irrigation use has steadily increased over the past decades, resulting in additional evaporation to the atmosphere, and increased precipitation. The precipitation stemming from groundwater irrigation (or Groundwater-dependent precipitation) has received little attention during recent years and is solely researched by the Eulerian model.

  4. 3. Carbon dioxide dynamics in agricultural streams : Investigation of two streams draining catchments dominated by agricultural land

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Albin Bostner; [2020]
    Nyckelord :Carbon dioxide; dynamics; streams; agriculture; oversaturation; metabolic control; hyrdological control; Koldioxid; koldynamik; bäckar; jordbruk; övermättat; metabolisk kontroll; hydrologisk kontroll;

    Sammanfattning : In recent years, streams draining agricultural land has been suggested to exhibit high carbon dioxide (CO2) concentrations when compared to streams draining other land-types. The transport of carbon from land to ocean is mainly occurring through the chain of inland waters, and with agricultural land today representing 40% of all continental area many of these inland waters are influenced by agricultural land.

  5. 4. Investigating the decrease ofgroundwater levels and the effect of fracture zone on recovery time: A case study of decrease in groundwater levels in a tunnel construction site in Vinsta, Stockholm

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Evgenia Kassiou; [2017]
    Nyckelord :Groundwater; spatial analysis; Modified Double Mass Statistical Analysis; 3D model; COMSOL Multiphysics; fracture zone; recovery time; soil layer;

    Sammanfattning : Groundwater is one of the main natural resources worldwide. Groundwater exists in aquifers below the earth surface and provides quantities of water for various purposes such as supply to households and businesses, public supply, drinking water supply, irrigation and agriculture. Sweden is also highly dependent on groundwater. LÄS MER

  7. 5. Risk management of groundwater drawdown in settlement sensitive areas.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Victoria Tisell; [2013]
    Nyckelord :Groundwater model; Settlement; Crystal Ball with Monte Carlo simulation; Risk analysis; Deterministic; Probabilistic;

    Sammanfattning : A new method for estimation of risks at settlement calculations is presented. By quantifying uncertainties of settlement calculations, it is possible to make risk analysis and to compare the costs of risk reducing efforts with the benefit these efforts would lead to. LÄS MER
