- In an analysis of food system sustainability challenges and solutions among Swedish food system actors using Q-methodology, five perspectives were identified. One of the main three perspectives placed the highest priority on reduced meat consumption, food waste, and climate impact in agriculture, but downplayed strategies highlighted in the national food strategy and social aspects, and can be interpreted as a diagnostic climate mitigation-oriented perspective that does not reflect current negotiated policy processes or ‘softer’ values of food. In an alternative regenerative perspective, industrialized large-scale farming and lack of internalization of external costs were regarded as the main problems, and diversity, soil health, and organic farming as the main solutions. Proponents of a third perspective regarded phasing out fossil fuels, increased profitability of companies, increased meat production, and self-sufficiency as high priorities. These contrasting views can be a major barrier to transforming the Swedish food system. However, a number of entry points for change (i.e. aspects highly important for some and neutral for others) were identified, including focusing on healthy diets and increased production of fruit and vegetables. Focusing on these can build trust among stakeholders before moving to discussions about the larger and more sensitive systemic changes needed. © 2022 The Authors

Växtnäring till jordbruket i osäkra tider – scenarier och dokumentation från en workshop
- 2024
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Mineralgödsel är en förutsättning för dagens konventionella jordbruk och utan mineralgödsel blir det problematiskt att få fram tillräckligt med foder och livsmedel. Sverige har ingen egen produktion av mineralgödsel och försörjningen är därför helt beroende av import. Denna rapport beskriver hur växtnäring hanteras ur beredskapssynpunkt i Sverige idag, och ger också en liten inblick i hur växtnäring har hanterats i tidigare kriser och pristoppar i andra länder. Rapporten beskriver också tre olika tänkbara krisscenarier där växtnäring behöver hanteras på olika sätt för att säkerställa livsmedelsförsörjningen i Sverige. Tidsperspektivet i scenarierna är relativt kort: ett fokuserar på hur växtnäringsförsörjningen kan lösas under den kommande växtodlingssäsongen medan de andra två scenarierna fokuserar på några år framåt i tiden. Scenarierna diskuterades på en workshop med deltagare från jordbruks- och växtnäringssektorn. I rapporten redovisas diskussionerna från workshopen. Under workshopen lyftes några brister i dagens system och förslag på vilket stöd och långsiktiga förändringar som behövs, för att säkra tillgången på växtnäring i Sverige under en kris: • I vardagen finns det ingen nationell eller regional planering av den svenska primärproduktionen och fördelningen av mineralgödsel eller andra insatsvaror till olika verksamheter, utan allt sköts av marknaden. Det finns därför ingen ansvarig offentlig aktör som har helhetsansvar för området. Vid en allvarlig brist på mineralgödsel kan det behövas någon som kliver in, säkrar leveranser och tar beslut om prioriteringar till olika verksamheter och eventuellt styrning av vem som odlar vad. Det kan även behövas någon som ansvarar för förebyggande arbete. • En trygg och resilient försörjning av växtnäring kommer att kräva en mångfald av lösningar. Dessa kräver i varierande grad samordning mellan marknadsaktörer och myndigheter. Vissa kan också kräva ny lagstiftning. Ett ”Gödselmedelskabinett” med ansvar att ta fram en strategi föreslogs. • Lagstiftning bör justeras alternativt införas för att utöka möjligheterna till miljö- och hälsomässigt säker återvinning av resurser från restflöden. Sådana ändringar skulle kunna förberedas redan nu, så att de snabbt kan träda i kraft i händelse av kris eller krig. • Sverige bör utveckla gemensamma strategier och avtal med andra länder, främst inom Norden, till exempel en nordisk strategi för växtnäringsfrågor.

Tidskriftsartikel (refereegranskat)abstract
- Adequate treatment of organic manures and digestates from livestock production should reduce environmental impacts and provide well-defined and attractive biofertlisers for a crop production market, which can promote the closure of the nutrient cycle in agriculture. In this sense, a survey was conducted during the autumn of 2021 to investigate Swedish farmers’ perspectives on organic fertilisers use. The survey consisted of an online questionnaire, which was distributed broadly in the social media, homepages, different types of networks and at course events in order to reach all types of farms. There were 22 questions focused on current use, reasons for current use and preferences for future use. The analysis of the 99 fully responded surveys, demonstrated that 43% of the respondents think that they will increase their use of organic fertilisers in the coming 5–10 years and 60% think that they will use manure digestate in different forms (both solid and liquid fractions). Soil improvement was the main reason to use organic fertilisers, but there were also preferences for organic fertilisers with fast release of nutrients. The risk of soil compaction was the main reason not to use organic fertilisers and based on the responses, pellets and granulates seem to be more interesting than liquids and solids in general. Animal manures dominate the current use of organic fertilisers in Sweden however, other types of organic waste such as digestate and digestate derived fertilisers seems appealing to Swedish farmers. In conclusion, from this survey with 62% of the respondees in crop production, we found several indications of that there is a potential for increased use of organic fertilisers in Sweden on farms with limited use today. We found an openness, a broad interest and a demand for different types of products of different forms and origin. Since this demand in the end will almost always depend on the price of products in relation to the price of mineral fertilisers, which are fluctuating, we see the need of policy incentives in order to stimulate initiatives for the development towards increased circularity of nutrients.

- Sugarcane ethanol systems can deliver large greenhouse gas emissions savings if emissions associated with land-use change are kept low. This qualitative study documents and analyzes actions and opinions among Brazilian farmers who shift to sugarcane production. Semi-structured interviews were held with 28 actors associated with sugarcane production in three different regions: one traditional sugarcane region and two regions where sugarcane is currently expanding. Most farmers considered sugarcane a land diversification option with relatively low economic risk, although higher risk than their previous land use. Beef production was considered a low-risk option, but less profitable than sugarcane. In conjunction with converting part of their land to sugarcane, most farmers maintained and further intensified their previous agricultural activity, often beef production. Several farmers invested in expanded production in other regions with relatively low land prices. Very few farmers in the expansion regions shifted all their land from the former, less profitable, use to sugarcane. Very few farmers in this study had deforested any land in connection with changes made when shifting to sugarcane. The respondents understand "environmental friendliness" as compliance with the relevant legislation, especially the Brazilian Forest Act, which is also a requirement for delivering sugarcane to the mills. Indirect land-use change is not a concern for the interviewed farmers, and conversion of forests and other native vegetation into sugarcane plantations is uncontroversial if legal. We derive hypotheses regarding farmers' actions and opinions from our results. These hypotheses aim to contribute to better understanding of what takes place in conjunction with expansion of sugarcane and can, when tested further, be of use in developing, e.g., policies for iLUC-free biofuel production.

Tidskriftsartikel (refereegranskat)abstract
- Livestock handling in dairy production is associated with a number of health and safety issues. A large number of fatal and nonfatal injuries still occur when handling livestock. The many animal handling tasks on a dairy farm include moving cattle between different locations, vaccination, administration of medication, hoof care, artificial insemination, ear tagging, milking, and loading onto trucks. There are particular problems with bulls, which continue to cause considerable numbers of injuries and fatalities in dairy production. In order to reduce the number of injuries during animal handling on dairy farms, it is important to understand the key factors in human-animal interactions. These include handler attitudes and behavior, animal behavior, and fear in cows. Care when in close proximity to the animal is the key for safe handling, including knowledge of the flight zone, and use of the right types of tools and suitable restraint equipment. Thus, in order to create safe working conditions during livestock handling, it is important to provide handlers with adequate training and to establish sound safety management procedures on the farm.

Anaerobic digestion of alfalfa silage with recirculation of process liquid

- Process liquid recirculation initially stimulated one-phase anaerobic digestion of alfalfa silage in two semi-continuously fed and stirred tank reactors. Thus, with increased pH, alkalinity and stability it was possible to increase the organic loading rate to 3 g VS L-1 d-1, as compared to 2.25 g VS L-1 d-1 in a control reactor without recirculation. However, the recirculation of liquid eventually caused an accumulation of organic and inorganic substances, leading to an inhibition of hydrolysis and methanogenesis. This inhibition of microbial activity was prevented in one of the processes by replacing 50% of the recirculated process liquid with water during the second half of the operation period. A multiple linear regression model of principal components using seven input variables explained the variance in output variables nearly as well as the original model using all 23 measured input variables. The results show that it is necessary to adjust the degree of liquid recirculation to reach an optimal process. © 2005 Elsevier Ltd. All rights reserved.

Ingår i: Food and Nutrition Research. - 1654-6628 .- 1654-661X. ; 55, s. 5929-
-
Tidskriftsartikel (refereegranskat)abstract
- Introduction and Aim: Studies show frequent use of nutrition claims and health claims in consumers’ choice offood products. The aim of the present study was to investigate how consumers’ thoughts about these claimsand food products are affected by various types of food-related experiences.Material and Methods: The data collection comprised 30 individual interviews among Swedish consumersaged 25 to 64 years.Results: The results indicated that participants who expressed special concern for their own and their families’health were eager to find out the meaning of concepts and statements made. A lack of understanding and lackof credibility of concepts and expressions often caused suspicion of the product. However, in some cases thiswas counterbalanced by confidence in manufacturers, retailers, and/or the Swedish food legislation.Discussion and Conclusion: To achieve effective written communication of food products’ health-conduciveproperties on food labels, there is a need to consider the importance many consumers attach to understandingthe meaning of concepts and expressions used and the importance of credibility in certain expressions.Consumers’ varying cognitive approaches are suggested as a basis for pre-tests of nutrition claims and healthclaims.

Tidskriftsartikel (refereegranskat)abstract
- A novel integrated process for recovery of protein-enriched biomasses from 5% presalting brines and spice brines of herring (Clupea harengus) was investigated by combining carrageenan- and/or acid-driven flocculation (F) plus dissolved air flotation (DAF). The F-DAF technique with carrageenan resulted in protein and lipid recoveries from 5% presalting brine of 78 and 38%, respectively. Without flocculation or with only acidification, protein and lipid recoveries in DAF were only 13 and 10%, respectively. Low protein and lipid recoveries, 8-12 and 1.8-8.2%, respectively, were also obtained when spice brine was subjected to only acidification and DAF. The protein content in dry biomasses from 5% presalting brine and spice brine was 36-43 and 13-16%, respectively. The corresponding lipid levels were 23-31 and 9-18%, respectively, with ash levels of 11-20 and 38-45%, respectively. Biomass proteins contained ≤45% essential amino acids, and the lipids had ≤16% long-chain n-3 polyunsaturated fatty acids. Freeze-dried spice brine biomasses were characterized by anchovy- and spice-related sensory attributes. 5% presalting brine biomasses were connected to fish and seafood attributes and showed gel forming capacity. The outlined F-DAF recovery system can thus recover both nutrients and interesting flavors from the herring process waters, which are currently lost from the food chain. © 2023 The Authors.
