  1. 1. Assessing water balance and yields in Malawian cropping systems : maize soybean and maize Gliricidia systems resilience against climate change

    University essay from SLU/Dept. of Soil and Environment

    Author : Danila Valeriano; [2024]
    Keywords : crop modelling; APSIM; Malawi; maize; soybean; Gliricidia; agroforestry; legume intercropping; climate predictions; climate adaptation; SDSM;

    Abstract : In Malawi, maize monocultures are increasingly susceptible to extreme weather patterns, causing considerable yield reduction and heightened food insecurity for smallholder farmers dependent on rainfed subsistence agriculture. Diversifying cropping systems is crucial for ensuring yield resilience. READ MORE

  3. 2. Assessment of Climate Change Impact on Rainfed Barley Production in the Mediterranean Basin : The Almeria province case study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Francesco Saretto; [2024]
    Keywords : Barley; Rainfed; Climate Change; AquaCrop; AquaCrop-OSPy; Mediterranean; Climate Change Adaptation; Crop Modeling; Agriculture; Irrigation;

    Abstract : The Mediterranean basin is widely recognized as a climate change hotspot, with climate models projecting increasingly warmer and drier conditions that will impact local ecosystems, communities, and economies. Agriculture will be among the most affected sectors, with harsher conditions for crops’ growth, greater water needs, and lower yields. READ MORE

  4. 3. Investigating the response of terrestrial evapotranspiration to droughts in Africa : A combined remote sensing and modeling approach

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Yang Foo; [2023]
    Keywords : earth observation; terrestrial evapotranspiration; drought; vegetation-climate interactions;

    Abstract : Climate change is posing a significant threat to terrestrial ecosystems worldwide, in part due to the more frequent occurrence of extreme climatic events such as droughts. While the importance of drought impacts on vegetation has been widely recognized, the time-dependent characteristics of drought-induced response remain insufficiently understood. READ MORE

  5. 4. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Carl Holmquist; [2023]
    Keywords : Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

    Abstract : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. READ MORE

  6. 5. Solubility of arsenic in untreated and ZVI-treated contaminated aquifer material

    University essay from SLU/Dept. of Soil and Environment

    Author : Oscar R. Davies; [2022]
    Keywords : Hjältevad; zerovalent iron; phosphate extraction; Oxalate extraction; Visual MINTEQ; geochemical modelling;

    Abstract : Arsenic (As) is a toxic element to all life and exists in nature both naturally and anthropogenically. Naturally As contaminated soils are formed due to high geogenic background As concentrations which is released when bedrock is eroded. Asia is a continent with a high amount of naturally As contaminated soils and groundwater. READ MORE
