  1. 1. En hållbart intensifierad slåttervall med vitklöver : en litteratursammanställning

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Johanna Forss; [2023]
    Keywords : etablering; kväve; skördesystem; Trifolium repens; vall; vitklöver;

    Abstract : Fördelarna med att inkludera vall i växtföljden är många, till exempel kolinlagring, markförbättrande egenskaper och ogräsbekämpning. Intresset för odling av vall ökar när det finns fler avsättningsmöjligheter och ses som ett medel för att uppnå en hållbar intensifiering av odlingssystemet. READ MORE

  3. 2. Water use efficiency in agricultural irrigation in Egypt: A qualitative study on the complexities of utilising fossil groundwater resources in the face of water scarcity

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Johannes David Huber; [2023]
    Keywords : Water scarcity; water use efficiency; agricultural irrigation; desert farming; sustainability; groundwater extraction; Nubian Sandstone Aquifer System NSAS ; Business and Economics;

    Abstract : This study examines the adaptive capacity of desert farming in Egypt to imminent water scarcity and discusses the sustainability of fossil groundwater extraction. Through qualitative semi-structured expert interviews, the study identifies clear research and data gaps related to the Nubian Sandstone Aquifer System (NSAS) and highlights the need for a nuanced approach to fossil groundwater extraction that focuses on water use efficiency improvements.

  6. 5. Spatio-temporal analysis of groundwater-dependent precipitation based on Lagrangian moisture tracking

    University essay from Stockholms universitet/Institutionen för naturgeografi

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

    Abstract : 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.
