    Towards a verifiable and secure data sharing platform for livestock supply chain2022Ingår i: Proceedings of the 2022 IEEE International Conference on Dependable, Autonomic and Secure Computing, International Conference on Pervasive Intelligence and Computing, International Conference on Cloud and Big Data Computing, International Conference on Cyber Science and Technology Congress, DASC/PiCom/CBDCom/CyberSciTech 2022, Institute of Electrical and Electronics Engineers Inc. , 2022Konferensbidrag (Refereegranskat)
    Abstract [en]

    The digitization of a supply chain involves satisfying several functional and non-functional context specific requirements. The work presented herein builds on efforts to elicit trust and profit requirements from actors in the Swedish livestock supply chain, specifically the beef supply chain. Interviewees identified several benefits related to data sharing and traceability but also emphasized that these benefits could only be realized if concerns around data security and data privacy were adequately addressed. We developed a data sharing platform as a response to these requirements. Requirements around verifiability, traceability, secure data sharing of potentially large data objects, fine grained access control, and the ability to link together data objects was realized using distributed ledger technology and a distributed file system. This paper presents this data sharing platform together with an evaluation of its usefulness in the context of beef supply chain traceability.

    Lean-inspired development work in agriculture: Implications for the work environment2020Ingår i: Agronomy Research, ISSN 1406-894X, E-ISSN 2228-4907, Vol. 18, nr 2, s. 324-345Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Farmers operate in a turbulent environment that includes international competition, weather conditions and animal behaviour, for example, and is difficult for them to control. However, economy and productivity always have a high priority. As a consequence, farms have started to implement lean-inspired work systems. At the same time, health and safety are of urgent concern in the sector. This article explores how famers apply lean-inspired work processes. It identifies work environment changes during and after a lean implementation, as well as possible developments in the work environment following implementation of the lean philosophy. Data were collected from three groups: lean, lean-light and development-inclined reference farms (in total 54 farms), using a questionnaire and interviews. The results indicate that a majority of the lean farms were applying several lean principles and tools, and the lean philosophy. The lean-light farms applied parts of the lean concept, while the reference farms applied some of the more general tools, used in lean and elsewhere, such as visualisation in various forms and to various extents. The results showed positive effects of lean on the psychosocial work environment, better work structure and improved information, communication and co-operation. The physical work environment was improved to some extent by lean, where advantages such as a more structured and practical work environment with less physical movements and locomotion could be noticed. The lean concept provided a more structured and systematic approach to dealing with work and production environmental issues, for managers as well as for employees.

    Animal welfare implications of digital tools for monitoring and management of cattle and sheep on pasture2021Ingår i: Animals, E-ISSN 2076-2615, Vol. 11, nr 3, artikel-id 829Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The opportunities for natural animal behaviours in pastures imply animal welfare benefits. Nevertheless, monitoring the animals can be challenging. The use of sensors, cameras, positioning equipment and unmanned aerial vehicles in large pastures has the potential to improve animal welfare surveillance. Directly or indirectly, sensors measure environmental factors together with the behaviour and physiological state of the animal, and deviations can trigger alarms for, e.g., disease, heat stress and imminent calving. Electronic positioning includes Radio Frequency Identification (RFID) for the recording of animals at fixed points. Positioning units (GPS) mounted on collars can determine animal movements over large areas, determine their habitat and, somewhat, health and welfare. In combination with other sensors, such units can give information that helps to evaluate the welfare of free-ranging animals. Drones equipped with cameras can also locate and count the animals, as well as herd them. Digitally defined virtual fences can keep animals within a predefined area without the use of physical barriers, relying on acoustic signals and weak electric shocks. Due to individual variations in learning ability, some individuals may be exposed to numerous electric shocks, which might compromise their welfare. More research and development are required, especially regarding the use of drones and virtual fences. © 2021 by the authors.

    Få ett gott djuröga med hjälp av eyetracking: en pilotstudie2020Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Can eyetracking as a tool be used to educate new staff at a farm?

    This pilot project evaluates the potential of eyetracking as a tool for training new staff on a farm in practical knowledge about animal welfare.

    A basic prerequisite for economically profitable animal production is healthy animals with good growth. Detecting animals in need of extra care during rounds is a challenge when there are many animals that need to be checked in a short time. The experience of the staff is an important component, but access to qualified staff is a scarce commodity. The experience of the skilled staff is rarely written down but constitutes a tacit knowledge that is very sensitive to whether staff quit or fall ill. Hiring foreign labor is becoming more common, in which case the potential to take part in the workforce's overall competence will determine how well the new workers will succeed in their tasks.

    By using technical tools such as eyetracking, you can record what a person is looking at in a certain environment. With this technology one could easily show and educate, e.g. staff, new employees, and students, what it is an experienced caretaker looks at when minding the animals. The technology makes it possible to visualize what an experienced caretaker is observing. In that way eyetracking has the potential to improve the working environment by streamlining the work of training new staff and getting everyone in the work team (experienced or not) to perform the tasks at the same high level as the most experienced.

    InfoXT - User-centric mobile information management in automated plant production2020Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Nordic knowledge and know-how in the area of agriculture and ICT was extracted and further developed in the joint Nordic project ‘InfoXT - User-centric mobile information management in automated plant production’. The aim of the project was to draw up basic recommendations and guidelines for a novel, intelligent, integrated information and decision support framework for planning and control of mobile working units. Project participants came from Aarhus University - Faculty of Agricultural Sciences, Helsinki University of Technology - Information and Computer Systems in Automation, MTT Agrifood Research Finland, Swedish Institute for Agricultural and Environmental Engineering and VTT - Technical Research Centre of Finland. The work was based on a systems analysis approach that utilised data from earlier and on-going Nordic research and new prototypes as a technology platform. An initial study among Swedish precision farmers revealed user needs in information- and technology-intensive farms. Against this background, a systems concept for information management in mobile plant production environments was designed. The concept was technically validated by implementing new parts in practice. The system usability of the concept was evaluated using scenarios and internet questionnaire in all Nordic countries. The resulting system concept functions as a common description of user-friendly information systems for all actors in the value chain.

    Process för bred analys av kunskapsbehov inom jordbruket2021Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Process to identify and prioritise farmers knowledge needs for the Swedish agriculture. Several studies have pointed out gaps and shortcomings in the knowledge chain in Swedish agriculture (Swedish Board of Agriculture 2019, OECD 2018). Two questions that have been raised are whether the research has focused on the knowledge needs farmers really have and how the cooperation among the actors along the knowledge chain works. The goal of this pilot project was to develop and test, in a small scale, a process to identify and classify knowledge needs of Swedish farmers, in collaboration with key stakeholders along the knowledge chain in the agricultural sector. The long-term goal is to scale up the process to a national level to assess farmers needs in Swedish agriculture. The purpose is to highlight what knowledge farmers request all over Sweden and to provide input to the prioritization of research and development funds. The project was carried out during the Cov-19 pandemic 2020-2021, which limited the possibility of physical meetings, and all meetings were therefore digital. Four digital workshops were conducted in slightly different ways, with farmers representing two geographical areas. Each workshop had a unique set-up of participating farmers. At the workshops, the farmers discussed and prioritized their various knowledge needs. The material from the workshops was compiled into categories and sent out for feedback to various experts, in the broad sense. The experts classified the needs according to what knowledge is already available and whether this knowledge is easily accessible. They were also asked to rank their top three most important knowledge needs for each category. A process to capture, classify and prioritise farmers' knowledge needs is presented and tested in this study. This process captures farmers' knowledge needs in a broad sense and is favourably to be used as a complement to knowledge gaps identified by specialised interest groups, such as trade associations or sector-specific centres, to provide a comprehensive picture of farmers' knowledge needs. By collaboratively highlighting and discussing farmers' knowledge needs in a broader context, the process has potential to increase cooperation and knowledge exchange between the actors in the agricultural knowledge chain.

    Monitoring live pig weight with a mobile imaging system2005Ingår i: Precision Livestock Farming 2005, 2005, s. 257-263Konferensbidrag (Refereegranskat)
    Abstract [en]

    Pig husbandry today has to be very efficient to manage the economic demands of finishing pigs. It is important for the farmer to optimize breeding and weight at slaughter in order to reach the weight interval for best payment and delivery increment at the slaughterhouse. To achieve the best economic production, feed consumption, death rate, and time to slaughter have to be minimized. The growth of the herd has to be monitored so that the farmer can control the feeding to reach optimum carcass weight and classification of meat percentage at the slaughterhouse. Ideally, the weight of the pig should be registered daily. Today, it is not possible to complete ordinary weighing daily as it is one of the most stressful, unhealthy, heavy and time demanding elements within pig husbandry. This paper presents the development of a mobile imaging system for live pig weight estimation in production conditions. The purpose of this project is to investigate if an optical weight estimator can be developed to estimate the individual weight of pigs in the same pen from images containing more than one pig. The optical weight estimator is designed to work in a production environment where transponder feeding is not available. Compared to similar studies, this study concentrates on conditions where several pigs are fed from the same feeding trough at set times, thus a mobile system was used. The adaptability of this mobile system makes it possible to use it in different stable environments. The optical weight estimator is attached to a carrier and the pigs are monitored during feeding. From the weighing system, pig growth, desired slaughter weight and shape information, as means to assistance in the estimation of meat percentage, can be approximated per pen. To be able to identify pigs ready for slaughter, the farmer has to be present to mark individual pigs that have reached the desired weight. The time for weighing pigs with the optical weight estimator is reduced by approximately 5 hours, from roughly 6 hours to 1 hour for 400 pigs. The relation between area and weight for pigs between 20 and 120 kg was similar to results presented in the literature (r2=0.97).

    Mapping spatial variation in growing willow using small UAS2009Ingår i: Precision Agriculture 2009 - Papers Presented at the 7th European Conference on Precision Agriculture, ECPA 2009, 2009, s. 485-492Konferensbidrag (Refereegranskat)
    Abstract [en]

    Attempts to reduce consumption of fossil fuels have led to increased use of biofuels. Although willow generates a high energy exchange and is profitable in relation to many other dedicated energy crops, there has been relatively low interest among farmers in growing willow. This low interest is expected to continue unless the profitability of willow growing is considerably increased, either by significantly reducing production costs or by increasing product price. This could be achieved if growers could guarantee production of a certain quantity and quality at a certain time, which would require e.g. a method to estimate standing biomass in willow plantations. This study evaluated if visual interpretation of low altitude aerial photography from a small unmanned aircraft can be used to detect and map differences in variety, homogeneity, and biomass density in growing willow. It is the initial part of a larger project to evaluate different remote sensing based methods for estimation of biomass in growing willow. The ability to accurately map within-field variability would be very useful since it enables more efficient stratified field sampling techniques to be used. If differences can be detected by means of visual interpretation it could mandate the development of more advanced automated image-analysis based tools for quantitative measurements. The results show that it was possible to map areas with different homogeneity with high spatial precision using the orthophoto mosaic images generated with the UAS, when considering both spectral and textural information. It was also possible to differentiate between different varieties of willow using the UAS, provided that single images were used for spectral differentiation and that the stands were sufficiently large.

    Measuring distribution accuracy of fertiliser using image analysis2005Ingår i: Precision Agriculture 2005, ECPA 2005, 2005, s. 557-563Konferensbidrag (Refereegranskat)
    Abstract [en]

    Spreading patterns from fertiliser spreaders are only occasionally measured in the field to ensure even distribution. In this study, the possibility of using image analysis to detect fertiliser granules automatically in images collected in field conditions was investigated. Images of the granules on the ground were taken right next to the location of the comparative collection trays. In these images, the granules were segmented automatically without changing any parameters between the different images and the area of each granule was converted into volume. This volume was then compared to the volume measured in the collection trays. The results indicate that the major distribution patterns from normalised volumes, calculated from the image analysis, closely follow the distribution patterns from the normalised fertiliser volumes measured within the collection trays. These results are valid for both centrifugal broadcasters and pneumatic distributors and are independent of the vegetation covers present in this study. As expected, the accuracy of the quantitative results from the image analysis decreased with increasing vegetation cover.

    Field specific overview of crops using UAV (Unmanned Aerial Vehicle)2007Ingår i: Precision Agriculture 2007 - Papers Presented at the 6th European Conference on Precision Agriculture, ECPA 2007, 2007, s. 357-364Konferensbidrag (Refereegranskat)
    Abstract [en]

    Data collection for precision agriculture has to be timely, cost effective and have minimum influence on the growing crop. Unmanned aerial vehicles (UAV) may provide unique spatial and temporal field specific information at a low cost. The objective of this project was to test a currently available, low-cost UAV technology and its potential usefulness for collecting information for precision agriculture. This system is the first fixed wing UAV approved for routine flying in uncontrolled airspace in Sweden. Single images and orthophoto mosaics of high-resolution true colour images have been created and compared to field measurements and the paper shows the potential of creating a fully automated aerial mapping system in the future. In this study, focus was set on the occurrence of weeds and N-content variations in wheat. Some comparison between UAV images and the quality of malting barley according to protein content was also made.A limitation in this study was the lack of image acquisition in the NIR spectral range. A NIR-enabled camera option is now available for the UAV-system and future studies of protein registration in grains will be made. Protein content proved to be difficult to measure without data from the NIR-spectral range. Valuable information on nitrogen deficiencies and weed concentration has been collected, indicating an acceptable image quality using the SmartOne UAV for precision agriculture purposes. This system shows great potential to be an important tool for future farm advisors to be able to make frequent, timely inspections of entire fields without any risk of soil compaction.
