  1. 1. Evaluation of Crop Water Use and Rice Yield Using Remote Sensing and AquaCrop Model for Three Irrigation Schemes in Sri Lanka

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Veronika Widengren; [2022]
    Keywords : WaPOR; remote sensing; evapotranspiration; crop water productivity; irrigation scheme; AquaCrop; Malwathu Oya; Sri Lanka; paddy rice; humid tropical climate; WaPOR; fjärranalys; evapotranspiration; vattenproduktivitet; bevattningssystem; AquaCrop; Malwathu Oya; Sri Lanka; ris; fuktigt tropiskt klimat;

    Abstract : With a changing climate and an increased competition over water resources for agricultural irrigation, the need to improve crop water productivity using time and cost-efficient methodologies have become critically important. The Malwathu Oya river basin in Sri Lanka is struggling with water scarcity, which threatens food security and the income of farmers. READ MORE

  3. 2. Growing crops or growing conflicts? : Climate variability, rice production and political violence in Vietnam

    University essay from Försvarshögskolan

    Author : William Sundelin; [2021]
    Keywords : climate change; climate variability; security; agriculture; food security; political violence; Vietnam;

    Abstract : This thesis contributes to research on climate change and violent conflict by testing the theory of a causal relationship between climate variability, agricultural production and political violence in the case of Vietnam 2010-2019. Climate-related negative shocks to agricultural production in developing countries are expected to lower the opportunity cost of violence through an income effect. READ MORE

  4. 3. Risodling i Mekongdeltat : hur påverkas risodling i Mekongdeltat av klimatförändringarna och vattenkraften?

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Mathilda Ogden; [2021]
    Keywords : Vietnam; Mekongdelta; risodling; klimatförändring; vattenkraft;

    Abstract : Uppsatsen redogör för hur klimatförändringen och vattenkraften i Mekongregionen påverkar risodling i Mekongdeltat samt vad det betyder för livsmedelssäkerheten och fattigdomsbekämpningen i Vietnam. Cirka 40% av Vietnams landyta används till jordbruk och Mekongdeltat är ett av världens största jordbrukssystem för risodling (Food and Agriculture Organization of the United Nations, 2018).

  5. 4. Isolation and cultivation of methanogenic archaea from serpentinization system at Chimaera Seeps, Turkey

    University essay from SLU/Department of Molecular Sciences

    Author : Bobby Zetterlind; [2020]
    Keywords : Archaea; methanogens; Chimaera seeps; serpentinization system; isolation; cultivation;

    Abstract : A methanogenic archaeon was successfully isolated from iron-rich environmental samples from the Chimaera seeps in Turkey by cultivation in anoxic media supplemented with H2/CO2 and an antibiotic, namely erythromycin. The morphological features of this methanogen were non-motile rod cells approximately 1.7 – 8.5 μm in length and 0. READ MORE

  6. 5. Environmental modeling study of water adequacy and yield from an irrigated rice field in Mali.

    University essay from KTH/Mark- och vattenteknik

    Author : Amhagiyorgis Tedla; [2015]
    Keywords : CoupModel; Yield; Irrigation rate; Evapotranspiration; Runoff; Nitrogen uptake and leaching;

    Abstract : A process oriented modeling of an irrigated rice field in a semi arid area of Mali has been done with the help of computational tool CoupModel. The model has been used to simulate two levels of irrigation rates, in an attempt to test and see adequacy of a recommended irrigation rate and its environmental impact over the current management.
