- There are a few things which are obviously a central part of everyone’s life, at all times, and all over the globe, and which are crucial for our wellbeing. Food is, like sex, such an essential ingredient of our life, an ingredient of what we expect of a good life. What is on our plates is always a result of nature and culture, to the extent that it may seem hard to find commonalities in our global diet. As academics we have asked different questions about food. For a long time these questions have been dominated by the quest to secure enough food and to improve what we have got. It is, however, noteworthy that we also always have asked the normative questions in relation to food: Is it right to eat this kind of food? Do we produce our food the right way? Is there injustice and bad power in the way we distribute the food? Are we lied to in regard to what is on our plate? When we enter the normative realm, we enter the realm of ethics, understood in a wide and comprehensive way. As all normative questions, we need to be well informed by knowledge about how the world is, and what is at stake and for whom. We call this food ethics. Food ethics raises issues and asks questions in relation to food all along the value chains. It also puts things into relation with each other. At the same time it disentangles complex heaps of factors and pieces of knowledge, and looks for guidance. It is issue driven, rather than interest driven. It unites scholars with farmers and fishermen, chefs with industry, consumers with lawyers, and food citizens with authorities. As a young field within academia it is important to guard against efforts to appropriate the field for narrow interests, and instead to combine the natural and social sciences in analysing and addressing the challenges. We do not necessarily call for the grand ethical theory that explains it all, but rather start with the simple things in a very complex overall picture. We want to draw attention to ethically significant facts, discuss problematic developments, point to genuine dilemmas, learn about food relevant contexts and history, and look for individual, professional and institutional responses to ethical challenges and issues. Thus, one of the missions of this new journal Food Ethics, is to widen the scope and the discussion on the topic, and to be inclusive in terms of who has something to contribute to the field. There is no escaping from confronting very complex issues when it comes to managing one of the most basic needs we all have, food. As editors of this new journal we maintain that food ethics deserves special and inter-disciplinary attention by researchers, that it is not sufficiently dealt with by what is currently known as bioethics, that it is intrinsically connected with the so-called grand societal challenges of our time, that it is a globally important field which demands particular attention to complexities and uncertainties, as much as it needs to be explicit about what values are at stake and for whom, and which normative principles it touches upon.

Tidskriftsartikel (refereegranskat)abstract
- Seaweed aquaculture can provide the growing human population with a sustainable source of proteins. Sea-based cultivation is an effective method for farming seaweeds on a large scale and can yield high biomass output. However, the quality and biochemical composition of the biomass is seasonally dependent, which limits the harvests to certain periods of the year. Here we show the possibility to extend the sea-based cultivation season of Ulva fenestrata when aiming for high protein levels, by post-harvest treatment in herring production process waters. We harvested U. fenestrata at an optimal period in terms of yield, but suboptimal in terms of protein content. We then cultivated the seaweed in onshore tank systems with the nutrient-rich process waters for 14 days. We monitored biomass yield, crude protein content, amino acid composition, and content of the health concerning metals arsenic, mercury, lead, and cadmium, as well as the sensory properties of the dried biomass. After cultivation in the process waters, biomass yields were 30 - 40% higher (210 – 230 g fresh weight) compared to in seawater (160 g fresh weight). Also, the crude protein and amino acid content increased three to five times in the process waters, reaching 12 - 17 and 15 – 21% dry weight, respectively. The protein enriched biomass followed food graded standards for heavy metal content, and consumption of the biomass does not exceed health based reference points. Additionally, no sensory attributes regarded as negative were found. This rapid, post-harvest treatment can help extend the cultivation season of sea-based seaweed farms, maximizing their output of sustainable proteins.

Food systems sustainability: For whom and by whom? – An examination of different 'food system change' viewpoints
- 2018

Konferensbidrag (refereegranskat)abstract
- The United Nations identifies the food crisis as one of the primary overarching challenges facing the international community. Different stakeholders in the food system have widely different perspectives and interests, and challenging structural issues, such as the power differentials among them, remain largely unexamined. These challenges make rational discourse among food system actors from different disciplines, sectors and levels difficult. These challenges can often prevent them from working together effectively to find innovative ways to respond to food security challenges. This means that finding solutions to intractable and stuck issues, such as the food crisis often stall, not at implementation, but at the point of problem identification. Food system sustainability means very different things to different food system actors. These differences in no way undermine or discount the work carried out by these players. However, making these differences explicit is an essential activity that would serve to deepen theoretical and normative project outcomes. Would the impact and reach of different food projects differ if these differences were made explicit? The purpose of this initial part of a wider food system research project is not to search for difference or divergence, with the aim of critique, but rather to argue that by making these differences explicit, the overall food system project engagement will be made more robust, more inclusive and more encompassing. This paper starts with some discussion on the different food system perspectives, across scales, regions and sectors but focuses primarily on the design of processes used to understand these divergent and at times contradictory views of what a sustainable food system may be. This paper draws on ongoing work within the Mistra Urban Futures project, using the food system projects in cities as diverse as Cape Town, Manchester, Gothenburg and Kisumu as sites for this enquiry.

Precaution and Ethics: Handling risks, uncertainties and knowledge gaps in the regulation of new biotechnologies
- 2017
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- This volume outlines and analyses ethical issues actualized by applying a precautionary approach to the regulation of new biotechnologies. It presents a novel way of categorizing and comparing biotechnologies from a precautionary standpoint. Based on this, it addresses underlying philosophical problems regarding the ethical assessment of decision-making under uncertainty and ignorance, and discusses how risks and possible benefits of such technologies should be balanced from an ethical standpoint. It argues on conceptual and ethical grounds for a technology neutral regulation as well as for a regulation that not only checks new technologies but also requires old, inferior ones to be phased out. It demonstrates how difficult ethical issues regarding the extent and ambition of precautionary policies need to be handled by such a regulation, and presents an overarching framework for doing so.

Unraveling the logics of landscape
- 2014
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Despite conceptual oscillations through times, the concept of landscape remains highly subjective, whereupon unraveling its 'logics' opens up to a plurality of interpretations. Accordingly, by focusing on the interconnections present in the non-haphazard production of landscape, this publication elaborates on how the rural landscape is valued, monitored, changed, harbored, used and misused, be it through actions, representations or metaphors. This book covers a broad range of topics, with contributions from scholars from more than 30 countries.

Biodiversity assessments in the 21st century: The potential of insect traps to complement environmental samples for estimating eukaryotic and prokaryotic diversity using high-throughput DNA metabarcoding.
- 2019

Ingår i: Genome. - : Canadian Science Publishing. - 1480-3321 .- 0831-2796. ; 62:3, s. 147-159

Tidskriftsartikel (refereegranskat)abstract
- The rapid loss of biodiversity, coupled with difficulties in species identification, call for innovative approaches to assess biodiversity. Insects make up a substantial proportion of extant diversity and play fundamental roles in any given ecosystem. To complement morphological species identification, new techniques such as metabarcoding make it possible to quantify insect diversity and insect-ecosystem interactions through DNA sequencing. Here we examine the potential of bulk insect samples (i.e., containing many non-sorted specimens) to assess prokaryote and eukaryote biodiversity and to complement the taxonomic coverage of soil samples. We sampled 25 sites on three continents and in various ecosystems, collecting insects with Slam-traps (Brazil) and Malaise-traps (South Africa and Sweden). We then compared our diversity estimates with the results obtained with biodiversity data from soil samples from the same localities. We found a largely different taxonomic composition between the soil and insect samples, testifying to the potential of bulk insect samples to complement soil samples. Finally, we found that non-destructive DNA extraction protocols, which preserve insect specimens for morphological studies, constitute a promising choice for cost-effective biodiversity assessments. We propose that the sampling and sequencing of insect samples should become a standard complement for biodiversity studies based on environmental DNA.

A New Format for Learning about Farm Animal Welfare
- 2011
-
Ingår i: Journal of Agricultural and Environmental Ethics. - : Springer Science and Business Media LLC. - 1187-7863 .- 1573-322X. ; 24:4, s. 367-379

Tidskriftsartikel (refereegranskat)abstract
- Farm animal welfare is a knowledge domain that can be regarded as a model for new ways of organizing learning and making higher education more responsive to the needs of society. Global concern for animal welfare has resulted in a great demand for knowledge. As a complement to traditional education in farm animal welfare, higher education can be more demand driven and look at a broad range of methods to make knowledge available. The result of an inventory on “farm animal welfare,” “e-learning,” “learning resources,” and “open educational resources” in three different search engines is presented. A huge amount of information on animal welfare is available on the Internet but many of the providers lock in the knowledge in a traditional course context. Only a few universities develop and disseminate open learning resources within the subject. Higher education institutions are encouraged to develop open educational resources in animal welfare for the benefit of teachers, students, society, and, indirectly, animal welfare.
