Meeting Sustainability Requirements for SRC Bioenergy: Usefulness of Existing Tools, Responsibilities of Involved Stakeholders, and Recommendations for Further Developments
- 2012
-
In: Bioenergy Research. - : Springer Science and Business Media LLC. - 1939-1242 .- 1939-1234. ; 5:3, s. 606-620
-
Journal article (peer-reviewed)abstract
- Short rotation coppice (SRC) is considered an important biomass supply option for meeting the European renewable energy targets. This paper presents an overview of existing and prospective sustainability requirements, Member State reporting obligations and parts of the methodology for calculating GHG emissions savings within the EU Renewable Energy Directive (RED), and shows how these RED-associated sustainability criteria may affect different stakeholders along SRC bioenergy supply chains. Existing and prospective tools are assessed on their usefulness in ensuring that SRC bioenergy is produced with sufficient consideration given to the RED-associated criteria. A sustainability framework is outlined that aims at (1) facilitating the development of SRC production systems that are attractive from the perspectives of all stakeholders, and (2) ensuring that the SRC production is RED eligible. Producer manuals, EIAs, and voluntary certification schemes can all be useful for ensuring RED eligibility. However, they are currently not sufficiently comprehensive, neither individually nor combined, and suggestions for how they can be more complementary are given. Geographical information systems offer opportunities for administrative authorities to provide stakeholders with maps or databases over areas/fields suitable for RED-eligible SRC cultivation. However, proper consideration of all relevant aspects requires that all stakeholders in the SRC supply chain become engaged in the development of SRC production systems and that a landscape perspective is used.

What is good about Sri Lankan homegardens with regards to food security? A synthesis of the current scientific knowledge of a multifunctional land-use system
- 2018
-
In: Agroforestry Systems. - : Springer Science and Business Media LLC. - 0167-4366 .- 1572-9680. ; 92:6, s. 1469-1484
-
Journal article (peer-reviewed)abstract
- Recently, there has been growing interest in agroforestry systems due to their great potential to mitigate threats to household food and nutrition security from soaring food prices but also as carbon sinks. In Sri Lanka, smallholder farms such as homegardens constitute a majority of Sri Lanka's total annual crop and timber production. Despite Sri Lankan homegardens being considered desirable and sustainable land-use systems, their role in food and nutrition security is not yet entirely understood. By synthesising scientific articles and grey literature we sought the link between food security and homegardens by quantifying their products or services and ascertaining whether food security characteristics are assessed as direct or indirect impacts. The results show that 27% of 92 identified articles directly quantified aspects that are relevant to food security. Another 51% of the articles quantified indirect aspects that have relevance for food security, including climate, soil, ecosystem services, structural and floristic diversity and economic aspects. Twenty-two percent of the articles were categorised as being qualitative or conceptual and contained no direct assessments or quantification of food security. The presence of significant merits from homegardens includes providing food security throughout the year at low-cost while sustaining numerous ecosystem services. This benefits particularly the poor farmers. However, many studies are descriptive and only provide location-specific information on single research focuses such as plant species, yield and management. There are few comparisons with crop land, forests or other production systems, and there is even less empirical evidence and quantification of the food security and other benefits. Seven areas where more scientific focus would be beneficial are identified. Homegardens are strong in national policies and to reach a greater level of efficiency within these activities our findings suggest more emphasis on a higher degree of inclusiveness of relevant stakeholders and long-term engagements with context specific guidance.

Extracting Urban Food Potential: design-based methods for digital and bodily cartography
- 2015
-
In: Future of Food: Journal on Food, Agriculture and Society. - 2197-411X. ; 3:1, s. 48-62
-
Journal article (peer-reviewed)abstract
- Sweden’s recent report on Urban Sustainable Development calls out a missing link between the urban design process and citizens. This paper investigates if engaging citizens as design agents by providing a platform for alternate participation can bridge this gap, through the transfer of spatial agency and new modes of critical cartography. To assess whether this is the case, the approaches are applied to Stockholm’s urban agriculture movement in a staged intervention. The aim of the intervention was to engage citizens in locating existing and potential places for growing food and in gathering information from these sites to inform design in urban agriculture. The design-based methodologies incorporated digital and bodily interfaces for this cartography to take place. The Urban CoMapper, a smartphone digital app, captured real-time perspectives through crowd-sourced mapping. In the bodily cartography, participant’s used their bodies to trace the site and reveal their sensorial perceptions. The data gathered from these approaches gave way to a mode of artistic research for exploring urban agriculture, along with inviting artists to be engaged in the dialogues. In sum, results showed that a combination of digital and bodily approaches was necessary for a critical cartography if we want to engage citizens holistically into the urban design process as spatial agents informing urban policy. Such methodologies formed a reflective interrogation and encouraged a new intimacy with nature, in this instance, one that can transform our urban conduct by questioning our eating habits: where we get our food from and how we eat it seasonally.

Garden Smellscape : experiences of plant scents in a nature-based intervention
- 2021
-
In: Frontiers in Psychology. - 1664-1078. ; 12, s. 1-10
-
Journal article (peer-reviewed)abstract
- This study explores how participants suffering from stress-related mental disorders describe their perception, interaction, and lived experience of garden smellscape during their nature-based rehabilitation. Natural elements, and especially nature smells, have been found to have a profound effect on stress reduction, suggesting an interesting link between odor in nature and stress reduction. The study was conducted as a longitudinal case-study, running over a period of 5 years, investigating participants’ perceptions of a garden smellscape, after completing a 12-weeks nature-based rehabilitation in Alnarp Rehabilitation Garden, Sweden. All participants were treated for stress-related mental disorders. Data were collected through retrospective semi-structured individual interviews and analyzed according to interpretative phenomenological analysis. The results revealed in what way nature odor (odor in nature) evoked associations, emotions, and physical reactions and provide examples of how nature scents function as a catalyst for sensory awareness and memories. Findings supported the understanding that experiencing the smell of plants, especially pelargonium, may facilitate stress reduction and support mental recovery in a real-life context. The results of the study can be used for several purposes; thus, they are relevant for actors within the development of nature-based therapy, as well as stakeholders within the horticultural industry.

Precaution and Ethics: Handling risks, uncertainties and knowledge gaps in the regulation of new biotechnologies
- 2017
-
Book (other academic/artistic)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.

Improved bio-energy yields via sequential ethanol fermentation and biogas digestion of steam exploded oat straw
- 2011
-
In: Bioresource Technology. - : Elsevier. - 0960-8524 .- 1873-2976. ; 102:6, s. 4449-4455
-
Journal article (peer-reviewed)abstract
- Using standard laboratory equipment, thermochemically pretreated oat straw was enzymatically saccharified and fermented to ethanol, and after removal of ethanol the remaining material was subjected to biogas digestion. A detailed mass balance calculation shows that, for steam explosion pretreatment, this combined ethanol fermentation and biogas digestion converts 85-87% of the higher heating value (HHV) of holocellulose (cellulose and hemicellulose) in the oat straw into biofuel energy. The energy (HHV) yield of the produced ethanol and methane was 9.5-9.8 MJ/(kg dry oat straw), which is 28-34% higher than direct biogas digestion that yielded 7.3-7.4 MJ/(kg dry oat straw). The rate of biogas formation from the fermentation residues was also higher than from the corresponding pretreated but unfermented oat straw, indicating that the biogas digestion could be terminated after only 24 days. This suggests that the ethanol process acts as an additional pretreatment for the biogas process.

Large-scale releases of native species : the mallard as a predictive model system
- 2015
-
Doctoral thesis (other academic/artistic)abstract
- Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed. The mallard (Anas platyrhynchos) is the most numerous and widespread duck in the world and a flagship in wetland conservation. It is also an important game species which is heavily restocked for hunting purposes, especially in Europe where over three million ducklings are released every year. Because of its hunted status, its abundance, and the number of released individuals, it can serve as a model species to study effects of releases, both for conservation and restocking for hunting, on wild populations. In this thesis the status of the mallard was assessed in the Nordic countries and the effects of releases on the wild populations were studied by mining historical ringing data, comparing morphology of present-day wild, farmed, and historical mallards, and analyzing phylogeography of wild and farmed mallards in Europe. The status of the mallard population in the Nordic countries are generally good, however, a joint effort of European countries is needed to monitor and manage the population. A significant difference between wild and farmed mallards concerning longevity, migration, bill morphology and genetic structure was also found, together with signs of cryptic introgression of farmed genotypes in the wild population with potential fitness reduction as a result. The effect is however limited by that only a fraction of released farmed mallards reach the breeding season due to low survival. A natural captive environment is crucial to keep individuals wild-like with high survival rates after release. However, with an introgression of potentially maladapted farmed genotypes leading to a reduction in fitness, a low survival of released mallards would favor the wild population. A legislative change regarding obligation to report numbers, provenance, and release sites of farmed mallard should be considered, together with practical solutions of ringing and genetic monitoring of released mallards.

Expanding arenas for learning hunting ethics, their grammars and dilemmas : An examination of young hunters' enculturation into modern hunting
- 2022
-
In: Sociologia Ruralis. - : Wiley. - 0038-0199 .- 1467-9523. ; 62:3, s. 632-650
-
Journal article (peer-reviewed)abstract
- Although hunting is declining in western countries, the number of people taking the hunting exam in Sweden are stable, and new demographic groups are becoming hunters. Through interviews done in Sweden with both new and experienced hunters, as well as focus groups with young hunters at agricultural colleges, we investigate how they navigate praxis and ethical frameworks taught in hunting. Using theories on moral learning, as well as Walzer's thick and thin moral argument, we contrast the views of these young hunters with the ethical principles outlined in the educational literature for the hunting exam. We then present how young hunters reasoned around issues regarding hunting ethics, animal welfare and the place of hunting in modern society, both inside and outside the classroom. The young hunters we spoke to acted as moderators of modern trends in hunting, often bringing 'destabilising' influences like social media and female hunters. Young hunters are enculturated into traditional hunting structures and, in the process, caught in a dialectic between modern influences and traditional hunting culture. Our findings highlight challenges such as 'false consensus' and 'ethical trade-offs' in the learning of hunting ethics, which emerge potentially due to a lack of space for deliberation on hunting ethics.

En studie om tillit till inventeringssystemet för stora rovdjur
- 2019
-
Reports (other academic/artistic)abstract
- Tillit, att lita på samhället och på sina medmänniskor, är samhällets kitt. Ett samhälle, inklusive dess olika komponenter, som präglas av hög tillit antas fungera bättre än om tilliten är låg. Syftet med vår studie är att utvärdera tilliten till inventeringssystemet för stora rovdjur bland de myndigheter och intresseorganisationer som är direkt berörda av systemet. På basis av intervjuer utvärderade vi tilliten genom sex olika delkomponenter; kommunikation,ansvars- och kompetensfördelning, resurser, respekt, kunskap och rättvisa. Vi har identifierat brister i alla sex delkomponenterna vilket sammantaget resulterar i att tilliten för systemet kan betecknas som låg. • Kommunikationen i systemet; hur kommunikationen sker, vad somkommuniceras, och på vilket sätt beslut kommuniceras upplevs som undermålig.• Ansvars- och kompetensfördelningen upplevs som otydlig. Det finns en klyfta mellan de som fastställer regler och riktlinjer och de som utför inventeringarna, varför relationerna präglas mer av kontroll och misstro än av handlingsutrymme och tillit.• Inventeringsresurserna räcker inte till eller prioriteras fel; t.ex. prioriteras varg på bekostnad av de övriga arterna. Det minskar förutsättningarna att fatta välgrundade beslut om ersättningar för rovdjurspredation ochom licens- och skyddsjakt.• Respekten för kunskap, näringsverksamhet och ideellt arbete upplevs som bristfällig. Respekten missgynnas också av den rigida kontrollkultur som upplevs ha utvecklats till följd av mål- och resultatstyrning i kombination med strikta inventeringskriterier.• Integrationen av ny kunskap är bristfällig. Bristen på ett systematiskt s.k. adaptivt lärande leder till att nya lösningar inte tillämpas eller utvecklas i tillräckligt hög grad.• Systemet upplevs som orättvist och slutet. En översyn av hur kostnader och nytta fördelas efterlyses av aktörerna, både vad gäller direkta kostnader,men även transaktionskostnader, dvs. kostnader förknippade med samråd och samverkan. Det är också oklart hur aktörerna aktivt tillåts delta i utvecklingen av systemet. Aktörerna lyfter fram en rad förslag till hur tilliten kan stärkas. Det utgör grunden till förbättringar som också kan accepteras av de flesta:• Inled ett systematiskt kvalitetssäkringsarbete med fokus på dialog och aktörssamverkan, till exempel inom ramen för Dialog för Naturvård.• Arbeta gemensamt fram en tydlig rollfördelning som beskriver vem som gör vad, när och varför inom hela inventeringskedjan, med syftet att öka förutsägbarheten för alla inblandade.• Skapa incitament och strukturer för adaptiv förvaltning inom hela inventeringskedjan,på alla nivåer.• Ta fram en översyn av hur kostnader och nytta fördelas för alla aktörer.Det ska inkludera direkta kostnader och transaktionskostnader, dvs. kostnader förknippade med samråd och samverkan.• Utveckla och effektivisera inventeringsmetoderna, gärna med ny teknik som DNA, kameror och drönare. Utöka samarbetet med forskningsprojekt som till exempel ScandCam.• Återkoppla direkt till intresseorganisationernas och allmänhetens observationerför att öka motivationen att rapportera.• Utveckla ett regelverk för de år där det saknas inventeringsdata (t.ex.på grund av snöbrist), genom till exempel en rutin för framskrivning av antalet djur baserat på trendanalys.• Minska fjärrstyrningen, NVs roll bör vara mer koordinerande än kontrollerande.• Verka för kunskapsintegration (s.k. kollektiv intelligens) genom att samordnakunskaper, vetenskaplig samt lokal och traditionell kunskap, så att det gagnar hela systemet.• Gör en översyn av hur resurser fördelas och prioriteras i systemet.

Biomass for energy, food and materials in an industrial society of 10 billion people
- 1996
-
In: Renewable Energy. ; 9:1-4, s. 926-929
-
Journal article (peer-reviewed)abstract
- In this paper we analyse the requirements of bioproductive land in a future industrial so-ciety of 10 billion people, with average per capita economic standard comparable to that of the industrialized countries of today. Despite significantly more efficient technology, lowering demand for both energy and material per service delivered, requirement for food and material alone will call for a heavily increased demand for bioproductive land for use in agriculture and silviculture. Large areas of short rotation energy plantations may be biophysically possible, but will clearly compete for available bioproductive land with agriculture and silviculture, as well as with preservation of the world's biodiversity. Therefore, the notion that there exists large areas of surplus or degraded land, which, without coming in conflict with food production and preservation of biodiversity, can be used for large energy plantations has not fully taken into account possible increased de-mand for bioproductive land from global industrialization and raising of the global average economic standard.

Effects of nutrient loading and fertilization at planting on growth and nutrient status of Lutz spruce (Picea x lutzii) seedlings during the first growing season in Iceland
- 2013
-
In: Scandinavian Journal of Forest Research. - : Taylor & Francis. - 0282-7581 .- 1651-1891. ; 28:7, s. 631-641
-
Journal article (peer-reviewed)abstract
- The low availability of nitrogen (N) is believed to be one of the major limiting factors of forest regeneration inIceland and frequently under Boreal conditions. Lutz spruce (Picea x lutzii Littl.) seedlings were nutrient loadedusing four fertilization regimes in the end of nursery rotation in autumn 2008 and planted in the following spring,with or without a single dose of fertilizer, on two treeless sites in N-Iceland with contrasting soil fertility.Measurements were made after one growing season. The highest loading level without additional field fertilizationincreased new needle mass by 122% and 152%, for the poor and more fertile site, respectively. The highest loadinglevel with field fertilization increased new needle mass equally, by 188% and 189%, for the poor and more fertilesite, respectively. Retranslocation of N, from old needles to current needles, increased with more loading.However, it was clear that nutrient loading could not replace field fertilization, as the seedlings generally showedan additive response to field fertilization and nutrient loading; doing both always gave the best results in seedlingperformance. As the study only covers field establishment during the first year, the long-term effect of nutrientloading of Lutz spruce cannot be predicted. However, it was concluded that loading might provide an additionalinput for faster plantation establishment during the first growing season after planting.

Labour input in Swedish intensive beef cattle production : physical work environment and motivation
- 2013
-
Doctoral thesis (other academic/artistic)abstract
- Red veal and young bull production are the two main intensive beef finishing systems in Sweden and utilise practically all male calves from the dairy and suckler cow herds. This thesis examined labour input and physical working conditions in the two systems in order to identify factors influencing these parameters. Data collection was mainly based on questionnaires, complemented by observations and interviews on farm visits, and related to the most common work tasks performed during different stages of the finishing period. Motivating factors among the Swedish intensive beef cattle producers were examined to analyse how individual orientations of motivation can help understanding farmers’ working conditions. Total time required per calf in red veal production (n=31) was 5.5, 1.9 and 2.0 h/calf for small, medium and large farms, respectively. This corresponded to a labour efficiency of 1.5, 0.6 and 0.6 min/calf/day. Labour efficiency on young bull farms (n=101) purchasing calves at median ages 21, 61, 121 and 180 days was 0.76, 0.94, 0.64 and 0.69 min/bull/day, respectively. No significant difference was found in labour efficiency between the four different finishing models on young bull farms. A possibility to improve labour efficiency by up to 63% was found when comparing the farms with the 25% highest and 25% lowest labour inputs. An effect of scale on labour input was found up to unit sizes of 550 red veal calves and 450 young bulls per year. The overall perceived physical strain was rated moderate exertion level. Cleaning tasks and handling of young bulls were rated with the highest physical strain. The prevalence of perceived musculoskeletal symptoms (MSD) was 51% and 65% in red veal and young bull farmers, respectively. MSD was most frequently reported in upper extremities and the back. Feeling stressed and worried, working in an unpleasant climate, high demands on the daily work pace and a high risk of injuries were reported by more than 20% of the 59 red veal and 98 young bull farmers surveyed. Work injuries were reported by 20% and 39% of red veal and young bull farmers, respectively. Swedish young bull and red veal producers with large, work-efficient farms were economically orientated, but just as highly motivated by several intrinsic values as those on small farms, indicating an unprecedented degree of multidimensionality. Identified measures of improvement of labour input and physical working conditions mainly related to frequently performed work tasks, animal handling, fragmentation of farm, and to improved facilities in the quarantine houses where proportion of labour input and the level of physical strain was typically high.

Climate change and ecological intensification of agriculture in sub-Saharan Africa : A systems approach to predict maize yield under push-pull technology
- 2023
-
In: Agriculture, Ecosystems and Environment. - 0167-8809 .- 1873-2305. ; 352
-
Journal article (peer-reviewed)abstract
- Assessing effects of climate change on agricultural systems and the potential for ecological intensification to increase food security in developing countries is essential to guide management, policy-making and future research. ‘Push-pull’ technology (PPT) is a poly-cropping design developed in eastern Africa that utilizes plant chemicals to mediate plant–insect interactions. PPT application yields significant increases in crop productivity, by reducing pest load and damage caused by arthropods and parasitic weeds, while also bolstering soil fertility. As climate change effects may be species- and/or context-specific, there is need to elucidate how, in interaction with biotic factors, projected climate conditions are likely to influence future functioning of PPT. Here, we first reviewed how changes in temperature, precipitation and atmospheric CO2 concentration can influence PPT components (i.e., land use, soils, crops, weeds, diseases, pests and their natural enemies) across sub-Saharan Africa (SSA). We then imposed these anticipated responses on a landscape-scale qualitative mathematical model of maize production under PPT in eastern Africa, to predict cumulative, structure-mediated impacts of climate change on maize yield. Our review suggests variable impacts of climate change on PPT components in SSA by the end of the 21st century, including reduced soil fertility, increased weed and arthropod pest pressure and increased prevalence of crop diseases, but also increased biological control by pests’ natural enemies. Extrapolating empirical evidence of climate effects to predict responses to projected climate conditions is mainly limited by a lack of mechanistic understanding regarding single and interactive effects of climate variables on PPT components. Model predictions of maize yield responses to anticipated impacts of climate change in eastern Africa suggest predominantly negative future trends. Nevertheless, maize yields can be sustained or increased by favourable changes in system components with less certain future behaviour, including higher PPT adoption, preservation of field edge density and agricultural diversification beyond cereal crops.

Biocultural Refugia : Combating the Erosion of Diversity in Landscapes of Food Production
- 2013
-
In: Ecology and Society. - 1708-3087. ; 18:4, s. UNSP 71-
-
Journal article (peer-reviewed)abstract
- There is urgent need to both reduce the rate of biodiversity loss caused by industrialized agriculture and feed morepeople. The aim of this paper is to highlight the role of places that harbor traditional ecological knowledge, artifacts, and methodswhen preserving biodiversity and ecosystem services in landscapes of food production. We use three examples in Europe ofbiocultural refugia, defined as the physical places that not only shelter farm biodiversity, but also carry knowledge and experiencesabout practical management of how to produce food while stewarding biodiversity and ecosystem services. Memory carriersinclude genotypes, landscape features, oral, and artistic traditions and self-organized systems of rules, and as such reflect adiverse portfolio of practices on how to deal with unpredictable change. We find that the rich biodiversity of many regionallydistinct cultural landscapes has been maintained through different smallholder practices developed in relation to localenvironmental fluctuations and carried within biocultural refugia for as long as millennia. Places that transmit traditionalecological knowledge and practices hold important lessons for policy makers since they may provide genetic and culturalreservoirs — refugia — for the wide array of species that have co-evolved with humans in Europe for more than 6000 thousandyrs. Biodiversity restoration projects in domesticated landscapes can employ the biophysical elements and cultural practicesembedded in biocultural refugia to create locally adapted small-scale mosaics of habitats that allow species to flourish and adaptto change. We conclude that such insights must be included in discussions of land-sparing vs. land-sharing when producingmore food while combating loss of biodiversity. We found the latter strategy rational in domesticated landscapes with a longhistory of agriculture

Assessing ecosystem services in perennial intercropping systems : participatory action research in Swedish modern agrofores
- 2014
-
In: Farming systems facing global challenges. - : IFSA Europe, Leibniz-Centre for Agricultural Landscape Research (ZALF), Humboldt-Universität zu Berlin. ; , s. 112-113, s. 1950-1959
-
Conference paper (other academic/artistic)abstract
- The focus of this paper is on how to assess ecosystem services in complex agroforestry systems using a case of edible forest gardens. Benefits of doing these assessments in a participatory learning and action research (PLAR) context are elaborated, as well as difficulties and questions that this has raised. The PLAR group comprised farmers on 13 smallholdings, researchers and a facilitator, which through collaboration and participatory methods have developed a general design of a forest garden, 60 m2 in size and established it on all 13 participating farms. Important values of the work are that ecosystem services are related to specific local contexts and that methodology for multi-criteria assessments of the generation of ecosystem services on a farm scale are being developed. Farmers engaged in formulating research questions, development of field trial designs, sampling and analysis of results improves the relevance and quality of the research as well as advance the adoption of new knowledge.
