  1. 1. Data driven crop disease modeling

    Författare :Priyamvada Shankar; Marcus Liwicki; Foteini Liwicki; Lili Jiang; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Crop Disease Prediction; Precision Agriculture; Digital Farming; Artificial Intelligence; Machine learning; Maskininlärning; Machine Learning;

    Sammanfattning : The concept of precision farming deals with the creation and use of data from machinery and sensors on and off the field to optimize resources and sustainably intensify food production to keep up with increasing demand. However, in the face of a growing amount of data being collected, smarter data processing and analysis techniques are needed and have prompted the evaluation and incorporation of artificial intelligence (AI) and machine learning (ML) techniques for multiple use cases right from seeding to harvesting.

  3. 2. Anaerobic digestion of crop residues at low temperatures

    Författare :Irene Bohn; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; kontroll av utsläpp; Miljöteknik; Environmental technology; pollution control; methanogens; low temperature; crop residues; Anaerobic digestion; farm-scale digestion; fluorescence in situ hybridization;

    Sammanfattning : Biogas is a renewable source of energy. Residues from agriculture contain considerable energy potential and are suitable substrates for biogas production, but in Sweden the utilization of these residues is low. The economic feasibility of biogas production in general is low, and only limited subsidies are provided by the state. LÄS MER

  4. 3. Bird Species in Urban and Agricultural Landscapes : Bird diversity patterns along an urbanisation gradient and crop damage caused by birds on the Deccan Plateau, India

    Författare :Manoj Ashokrao Kale; Prosun Bhattacharya; Gabor L. Lövei; Peter Kjellander; KTH; []
    Nyckelord :Bird assemblage structure; Forest-urban gradient; Scale-sensitive diversity; Crop depredation; Crop damage assessment; Deccan Plateau; India.; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : The major human activities that have transformed the Earth include agriculture and urbanization. The present study was conducted to contribute to a description of the effect on birds of urbanization and agriculture in an Indian region. LÄS MER

  5. 4. Evaluation of microbial health risks associated with the reuse of source-separated humna urine

    Författare :Caroline Höglund; KTH; []
    Nyckelord :urine-separation; urine; wastewater systems; wastewater reuse; recycling; enteric pathogens; faecal sterols; indicator bacteria; hygiene risks; microbial persistence; microbial risk assessment; QMRA; fertiliser; crop;

    Sammanfattning : Human excreta contain plant nutrients and have the potentialto be used as a fertiliser in agriculture. Urine contributesthe major proportion of the nutrients (N, P and K) in domesticwastewater whereas faeces contribute a smaller amount andinvolves greater health risks if reused due to the possiblepresence of enteric pathogens.

  7. 5. Soil Salinity and Crop Yield at El-Salam Canal Area, Egypt

    Författare :Yasser Hamed Abd El Mageed; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; El-Salam Canal; Egypt; Salinity; Crop yield; Arid;

    Sammanfattning : Soil salinity and solute movements through the soil are considered the most important challenge facing agriculture in Arid and Semiarid regions (e.g., Egypt). LÄS MER
