Paths to a sustainable food sector guided by LCA – exemplified by pork production
- 2014
-
Conference paper (other academic/artistic)abstract
- To describe a more sustainable food sector, a supply chain approach is needed. Changing supply chains inevitably means that a range of attributes of the product and its system will change. This project will take on this challenge and deliver detailed descriptions of supply chains of six commodities from a Swedish region in 2012; Milk, cheese, beef, pork, chicken and bread. The set-up of the project was that experts on production along the supply chain design environmentally improved systems. The next step was to challenge the improvements considering their possible consequences on products and systems from different perspectives: food safety, sensory qualities, animal welfare, and consumer appreciation and (only for primary production) costs. The final supply chains were quantified by life cycle assessment (LCA), and they were again assessed from the perspectives mentioned above. Results will be generated during August 2014 and comprise both single-product LCA and region-wide impacts of the future scenarios.

Nulägesanalys trädgård
- 2018
-
Reports (pop. science, debate, etc.)abstract
- Rapporten Nulägesanalys - trädgård har genomförts inom ramen för projektgruppen Insatsstyrka trädgård. Syftet med inventeringen har varit att ge svar på vem som jobbar med trädgårdsvetenskap, vilka forskargrupper och med vilka forskningsämnen, samt identifiera framtida arbetsfält inom ämnet trädgårdsvetenskap och därmed ge uppslag för framtida utveckling av forskningsfält, utbildning och samverkan. I detta ingår att kartlägga trädgårdsvetenskaplig forskning, utbildning och samverkan vid SLU. Nulägesanalysen förväntas därmed ge en grund för fortsatt strategiskt arbete med att utveckla ämnet trädgårdsvetenskap (Horticultural Science) utifrån inventerade resurser och förutsättningar.

Timed Up-and-Go Dual-Task Testing in the Assessment of Cognitive Function : A Mixed Methods Observational Study for Development of the UDDGait Protocol
- 2020

Journal article (peer-reviewed)abstract
- New methods to screen for and identify early-stage dementia disorders are highly sought after. The purpose of this pilot study is to develop a study protocol for a dual-task test aimed at aiding the early detection of dementia disorders. We used the Timed Up-and-Go (TUG) test, which is a mobility task involving starting in a sitting position, standing up, walking three meters to cross a line on the floor, turning around, walking back and sitting down again. We combined TUG with the verbal task of naming different animals. Pilot study participants were 43 individuals with and without established dementia diagnoses who attended a clinic for memory assessment. Video-recorded test performances were systematically analysed. Deviant test performances concerning the interplay between test administration and participants' responses to the assessment instructions were revealed and led to refinements being made to the final study protocol. Exploration of the dual-task test outcome measures in a sub-sample of 22 persons, ten with and twelve without dementia, indicated that step-length and number of named animals after the turning point of the dual-task test might constitute appropriate measures for examining this kind of sample. We concluded that the refined study protocol is feasible for testing individuals undergoing initial memory assessments and healthy controls. Follow-up studies with larger samples are being carried out and will bring new knowledge to this area of research. It may also provide an opportunity for further studies exploring possibilities for broad clinical implementation.

Paths to a sustainable food sector: integrated design and LCA of future food supply chains : the case of pork production in Sweden
- 2016
-
In: The International Journal of Life Cycle Assessment. - : Springer Ferlag. - 0948-3349 .- 1614-7502. ; 21:5, s. 664-676

Journal article (peer-reviewed)abstract
- Purpose: To describe a more sustainable food sector, a supply chain approach is needed. Changing a supply chain inevitably means that various attributes of the product and its system will change. This project assumed this challenge and delivered detailed descriptions, life cycle assessment (LCA) evaluations, and consequence assessments of the supply chains of six commodities, i.e., milk, cheese, beef, pork, chicken, and bread, from a Swedish region. This paper presents results for the pork supply chain. Methods: In the project setup, experts on production along supply chains designed three scenarios for environmentally improved systems. These scenarios, i.e., the ecosystem, plant nutrients, and climate scenarios, were intended to address different clusters of environmental goals. The next step was to challenge these scenarios by considering their possible consequences for products and systems from the food safety, sensory quality, animal welfare, consumer appreciation, and (for primary production only) cost perspectives. This led to changes in production system design to prevent negative consequences. The final supply chains were quantified using LCA and were again assessed from the three perspectives. Results and discussion: The scenario design approach worked well, thoroughly and credibly describing the production systems. Assessment of consequences bolstered the credibility and quality of the systems and results. The LCA of pig production and smoked ham identified large potentials for improvement by implementing available knowledge: global warming potential (GWP) could be reduced 21–54 % and marine eutrophication by 14–45 %. The main reason for these improvements was improved productivity (approaching the best producers’ current performance), though dedicated measures were also important, resulting in increased nitrogen efficiency, more varied crop rotations for crop production and better production management, and improved animal health and manure management for animal production. Reduced post-farm wastage contributed as did reduced emissions from fertilizer production. Conclusions: The working approach applied was successful in integrating LCA research with food system production expertise to deliver results relevant to supply chain decision-makers. The consequence assessments brought considerable value to the project, giving its results greater credibility. By introducing constraints in the form of “no negative consequences and no increased costs,” the work was “guided” so that the scenario design avoided being hampered by too many opportunities.

Seroprevalence of tick-borne encephalitis virus and vaccination coverage of tick-borne encephalitis, Sweden, 2018 to 2019
- 2024

In: Euro surveillance : bulletin Europeen sur les maladies transmissibles = European communicable disease bulletin. - : European Centre for Disease Control and Prevention (ECDC). - 1560-7917 .- 1025-496X. ; 29:2

Journal article (peer-reviewed)abstract
- BackgroundIn Sweden, information on seroprevalence of tick-borne encephalitis virus (TBEV) in the population, including vaccination coverage and infection, is scattered. This is largely due to the absence of a national tick-borne encephalitis (TBE) vaccination registry, scarcity of previous serological studies and use of serological methods not distinguishing between antibodies induced by vaccination and infection. Furthermore, the number of notified TBE cases in Sweden has continued to increase in recent years despite increased vaccination.AimThe aim was to estimate the TBEV seroprevalence in Sweden.MethodsIn 2018 and 2019, 2,700 serum samples from blood donors in nine Swedish regions were analysed using a serological method that can distinguish antibodies induced by vaccination from antibodies elicited by infection. The regions were chosen to reflect differences in notified TBE incidence.ResultsThe overall seroprevalence varied from 9.7% (95% confidence interval (CI): 6.6-13.6%) to 64.0% (95% CI: 58.3-69.4%) between regions. The proportion of vaccinated individuals ranged from 8.7% (95% CI: 5.8-12.6) to 57.0% (95% CI: 51.2-62.6) and of infected from 1.0% (95% CI: 0.2-3.0) to 7.0% (95% CI: 4.5-10.7). Thus, more than 160,000 and 1,600,000 individuals could have been infected by TBEV and vaccinated against TBE, respectively. The mean manifestation index was 3.1%.ConclusionA difference was observed between low- and high-incidence TBE regions, on the overall TBEV seroprevalence and when separated into vaccinated and infected individuals. The estimated incidence and manifestation index argue that a large proportion of TBEV infections are not diagnosed.
