    Sammanfattning : Popular Abstract in Swedish Ökad livsmedelsproduktion utgör ett viktigt steg för att uppnå livsmedelssäkerhet i Kamerun. Under det senaste halvseklet har ökningen av produktionen i huvudsak uppnåtts genom ökad uppodling. LÄS MER

  4. 3. The relationship between climate, disease and coffee yield: optimizing management for smallholder farmers

    Författare :Biruk Ayalew Nurihun; Ayco J. M. Tack; Kristoffer Hylander; Ivette Perfecto; Stockholms universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Agroforestry; Arabica coffee; climate change; fungal disease; host-hyperparasite interaction; insect pest; minimum temperature and maximum temperature; shade cover; shade tree species; smallholder farmers; yield; Ecology and Evolution; ekologi och evolution;

    Sammanfattning : Climate change and diseases are threatening global crop production. Agroforestry systems, which are characterized by complex multispecies interactions, are considered to provide nature-based solutions for climate change mitigation and pest and disease regulation. LÄS MER

  5. 4. 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.

  7. 5. 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
