  2. 1. Data driven crop disease modeling

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

    Abstract : 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.

  4. 2. Food security in a changing climate : The role of cropland intensification and land acquisitions across Africa

    Author : Altaaf Mechiche-Alami; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agriculture; land grabbing; sustainability science; Network Analysis; Earth observation; Crop model;

    Abstract : Food security is one of the world’s greatest challenges. The current food system shows an entanglement across the globe which means that local farmers reliant on subsistence agriculture no longer operate in isolation of larger-scale processes within the global economy or the changing biophysical system of the planet.

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

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

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

  6. 4. Crop and weed discrimination using computer vision

    Author : Maria Persson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image analysis; Crops; Weeds; Other information technology; Övrig informationsteknik;

    Abstract : The thesis is concerned with computer vision in ecological and precision agriculture aiming to identify crops and weeds in images of crop rows. The identification of plants can be done by extracting the plants in the image and classifying them as a crop or weed depending on the shape and color. READ MORE

  7. 5. Potential impact of climate change on European agriculture: a case study of potato and Colorado potato beetle

    Author : Bakhtiyor Pulatov; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Colorado potato beetle; climate change; day length; degree day model; frost damage; distribution; temperature; potato; regional climate model; synchrony;

    Abstract : European agriculture is facing the challenge of managing the impact of climate change on food security. Agriculture in a northern temperate climate is likely to benefit from higher temperature and longer growing season while, in the south, crop productivity is likely to decline. READ MORE
