  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. High levels of nickel from sulphide soil in Umeå's raw water : Modeling of groundwater flow and mass transport in Forslunda aquifer

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Merhawi Belai; [2024]
    Keywords : nickel; sulfide; sulphide; groundwater; modeling; mass transport; Feflow; Umeå; nickel; sulfid; monosulfid; grundvatten; modellering; masstransport; Feflow; Umeå;

    Abstract : The raw water in some of Umeå's abstraction wells has shown high nickel levels for more than a decade. The cause has not been determined but there is an investigation from 2010 where the results indicate sulphide clay found adjacent to two basins used for artificial infiltration. READ MORE

  5. 4. Näringsförluster från sju jordbruksområden nära Mälaren

    University essay from SLU/Dept. of Soil and Environment

    Author : Sally Karlsson Bondesson; [2024]
    Keywords : avrinningsområde; belastning; fosfor; kväve; S-HYPE; retention; typområden på jordbruksmark; vattenflöde; VISS; våtmark;

    Abstract : Ett av Sveriges miljömål är ”ingen övergödning” vilket innebär att gödande ämnen inte ska ha negativ inverkan på människor, biologisk mångfald eller mark-och vattenanvändning (Naturvårds-verket 2023). Näringsämnena fosfor och kväve och förlusten av dessa från framför allt jordbruksmark är en av orsakerna till övergödning i sjöar, hav och vattendrag. READ MORE

  6. 5. Techno-economic analysis and simulation of low temperature district heating networks

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Ilia Iarkov; [2023]
    Keywords : Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

    Abstract : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. READ MORE
