Scoping Report on Socio-Economic and Land Use Dynamics in the Stockholm-Mälar Region
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This scoping report for the COMPLEX work package 4 (WP4) on Socio-Economic and Land Use Dynamics in the Stockholm-Mälar Region has several objectives. The first is to present and outline the state-of-the-art, including a literature review, with regard to complex pathways to a low carbon society, with special relevance to the Stockholm-Mälar region. It will do so in a larger context of complex socio-natural systems, with an emphasis on a green economy, bioen-ergy and land use, as well as on societal transformation and behavioural change. Another objec-tive is to inform primarily our partners in COMPLEX, but also others who might be interested, including stakeholders in our study region. Perhaps the most important objective with this re-port is to provide a basis for the collaborative work within our work package, and with our col-leagues elsewhere. In this second revised version of the report, we have extended some parts, and shortened others, depending on suggestions and interesting new information. A part of this new information has come from a stakeholder workshop held in Sigtuna in early 2014, which to a great extent could contribute to a more elaborate analysis of stakeholder and policy maker positions. In addition, there is now a more extensive description of relevant land use modelling. The illustrations included in this report are extracted from scientific articles and other material that we are referring to. Their origin is explicitly cited but no copyright authorization has been requested, while this report is intended primarily for internal spread and use within the COM-PLEX consortium and its networks.

Specific SCAR markers and multiplex real-time PCR for quantification of two Trichoderma biocontrol strains in environmental samples
- 2011

Tidskriftsartikel (refereegranskat)abstract
- Several strains from the genus Trichoderma (Ascomycetes, Hypocreales) are commercially used as biocontrol agents, e.g. in formulations containing the two Trichoderma strains IMI206039 (Hypocrea parapilulifera B.S. Lu, Druzhinina & Samuels) and IMI206040 (T. atroviride P. Karst). To quantify the presence of the two isolates after application, we developed primers for SCAR markers (Sequence-Characterised Amplified Region). In order to quantify both fungal strains simultaneously, we also designed fluorophore-labelled probes distinguishing the two strains, to be used in combination with the SCAR primers. In incubations of two different soils, artificially inoculated and maintained under controlled conditions, the quantification through amplification with the SCAR markers in qPCR and through colony-forming units from plate counting correlated well. Further tests of the markers on samples taken from a golf green treated with a product containing both strains indicated that the two biocontrol strains did not establish, either on the golf green or in the surrounding area.

Tidskriftsartikel (refereegranskat)abstract
- There is a considerable amount of literature dealing with inference about the parameters in a heteroscedastic one-way random-effects ANOVA model. In this paper, we primarily address the problem of improved quadratic estimation of the random-effect variance component. It turns out that such estimators with a smaller mean squared error compared with some standard unbiased quadratic estimators exist under quite general conditions. Improved estimators of the error variance components are also established.

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.

Tillstånd och trender för arter och deras livsmiljöer – rödlistade arter i Sverige 2015
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- 2015 års upplaga av den svenska rödlistan är den fjärde i ordningen. Den är baserad på IUCN:s rödlistningskriterier och revideras vart femte år. I rödlistan bedöms risken som enskilda arter av djur, växter och svampar löper att försvinna från Sverige. Bedömningen utförs av ArtDatabankens medarbetare i samverkan med över 100 externa experter, indelade i 14 expertkommittéer för olika organismgrupper. Under arbetet med 2015 års rödlista har tillstånd och trender bedömts för 21 600 arter och 1 318 lägre taxa (apomiktiska arter, underarter och varieteter), sammanlagt ca 22 900 taxa. Av de bedömda arterna klassificerades 2 029 som hotade (kategorierna CR, EN och VU) och 4 273 som rödlistade (inkluderar även kategorierna NT, RE och DD). Förhållandet mellan antalet rödlistade och antalet bedömda arter ar 19,8 %, vilket är ungefär samma värde som 2010 och 2005. I denna rapport jämförs antalet och andelen rödlistade arter mellan olika organismgrupper, biotoper, substrat och påverkansfaktorer. Texten ar indelad i en allmän del och åtta kapitel inriktade på olika landskapstyper. Landskapstyperna utgör en grov indelning av landets miljöer enligt följande kategorier: Skog, Jordbrukslandskap, Urbana miljöer, Fjäll, Våtmarker, Sötvatten, Havsstränder och Havsmiljöer. Skogen och jordbrukslandskapet är de artrikaste landskapstyperna med 1 800 respektive 1 400 arter som har en stark anknytning dit, och ytterligare flera hundra arter som förekommer där mer sporadiskt. De faktorer som påverkar flest rödlistade arter i Sverige är skogsavverkning och igenväxning, som båda utgör ett hot mot vardera ca 30 % av de rödlistade arterna. Avverkning minskar arealen av skog där naturliga strukturer och naturlig dynamik upprätthålls, och den orsakar därmed förlust av livsmiljöer. Igenväxning orsakas av ett antal faktorer, bland annat upphörande hävd (bete och slåtter), gödsling, trädplantering och brist på naturliga störningsregimer som t.ex. regelbundna översvämningar kring vattendrag och sjöar. Andra viktiga påverkansfaktorer är fiske, torrläggning av våtmarker, tillbakagång hos värdarter (främst alm och ask som drabbats av invasiva svampsjukdomar), klimatförändringar och konkurrens från invasiva arter. IUCN:s rödlisteindex beräknas för ett urval av de bedömda organismgrupperna. Rödlisteindex visar att skillnaderna mellan rödlistorna från 2000, 2005, 2010 och 2015 är små. Ett par undantag finns dock. Groddjur och stora däggdjur har fått en något förbättrad situation sedan 2000. Totalt förefaller det ändå som att trycket mot Sveriges artstock har förblivit relativt konstant under de senaste 15 åren.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Beneficial land use change: Strategic expansion of new biomass plantations can reduce environmental impacts from EU agriculture
- 2020
-
Ingår i: Global Environmental Change. - : Elsevier BV. - 0959-3780 .- 1872-9495. ; 60
-
Tidskriftsartikel (refereegranskat)abstract
- Society faces the double challenge of increasing biomass production to meet the future demands for food, materials and bioenergy, while addressing negative impacts of current (and future) land use. In the discourse, land use change (LUC) has often been considered as negative, referring to impacts of deforestation and expansion of biomass plantations. However, strategic establishment of suitable perennial production systems in agricultural landscapes can mitigate environmental impacts of current crop production, while providing biomass for the bioeconomy. Here, we explore the potential for such “beneficial LUC” in EU28. First, we map and quantify the degree of accumulated soil organic carbon losses, soil loss by wind and water erosion, nitrogen emissions to water, and recurring floods, in ∼81.000 individual landscapes in EU28. We then estimate the effectiveness in mitigating these impacts through establishment of perennial plants, in each landscape. The results indicate that there is a substantial potential for effective impact mitigation. Depending on criteria selection, 10–46% of the land used for annual crop production in EU28 is located in landscapes that could be considered priority areas for beneficial LUC. These areas are scattered all over Europe, but there are notable “hot-spots” where priority areas are concentrated, e.g., large parts of Denmark, western UK, The Po valley in Italy, and the Danube basin. While some policy developments support beneficial LUC, implementation could benefit from attempts to realize synergies between different Sustainable Development Goals, e.g., “Zero hunger”, “Clean water and sanitation”, “Affordable and Clean Energy”, “Climate Action”, and “Life on Land”.

Meeting Sustainability Requirements for SRC Bioenergy: Usefulness of Existing Tools, Responsibilities of Involved Stakeholders, and Recommendations for Further Developments
- 2012

Tidskriftsartikel (refereegranskat)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.

Simulating wind disturbance impacts on forest landscapes: Tree-level heterogeneity matters
- 2014
-
Ingår i: Environmental Modelling and Software. - : Elsevier BV. - 1364-8152 .- 1873-6726. ; 51, s. 1-11
-
Tidskriftsartikel (refereegranskat)abstract
- Wind is the most detrimental disturbance agent in Europe's forest ecosystems. In recent years, disturbance frequency and severity have been increasing at continental scale, a trend that is expected to continue under future anthropogenic climate change. Disturbance management is thus increasingly important for sustainable stewardship of forests, and requires tools to evaluate the effects of management alternatives and climatic changes on disturbance risk and ecosystem services. We here present a process-based model of wind disturbance impacts on forest ecosystems, integrated into the dynamic landscape simulation model iLand. The model operates at the level of individual trees and simulates wind disturbance events iteratively, i.e., dynamically accounting for changes in forest structure and newly created edges during the course of a storm. Both upwind gap size and local shelter from neighboring trees are considered in this regard, and critical wind speeds for uprooting and stem breakage are distinguished. The simulated disturbance size, pattern, and severity are thus emergent properties of the model. We evaluated the new simulation tool against satellite-derived data on the impact of the storm Gudrun (January 2005) on a 1391 ha forest landscape in south central Sweden. Both the overall damage percentage (observation: 21.7%, simulation: 21.4%) as well as the comparison of spatial damage patterns showed good correspondence between observations and predictions (prediction accuracy: 60.4%) if the full satellite-derived structural and spatial heterogeneity of the landscape was taken into account. Neglecting within-stand heterogeneity in forest conditions, i.e., the state-of-the-art in many stand-level risk models, resulted in a considerable underestimation of simulated damage, supporting the notion that tree-level complexity matters for assessing and modeling large-scale disturbances. A sensitivity analysis further showed that changes in wind speed and soil freezing could have potentially large impacts on disturbed area and patch size. The model presented here is available as open source. It can be used to study the effects of different silvicultural systems and future climates on wind risk, as well as to quantify the impacts of wind disturbance on ecosystem services such as carbon sequestration. It thus contributes to improving our capacity to address changing disturbance regimes in ecosystem management. (C) 2013 Elsevier Ltd. All rights reserved.

Bekämpningsmedel i vattendrag från områden med odling av trädgårdsgrödor under 2008
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Den nuvarande miljöövervakningen av bekämpningsmedel (växtskyddsmedel) är främst inriktad mot att undersöka eventuellt läckage av växtskyddsmedel som används inom jordbruket. Däremot saknar vi kunskap om hur dessa medel uppträder i miljön vid användning inom trädgårdsodlingen. I vissa delar av södra Sverige finns betydande områden med frilandsodling av bär, frukt och grönsaker, samt växthusanläggningar. Växthus har i vissa sammanhang betraktats som ’slutna miljöer’. Detta har gjort att man inte alltid haft samma höga krav när man bedömt risken för skadliga effekter i omgivande vatten av växtskyddsmedel som används i just växthus jämfört med användning på våra åkrar.Syftet med undersökningen var att utveckla kunskapen om eventuellt läckage av växtskyddsmedel som används inom frilandsodling av trädgårdsgrödor och i växthus till vatten. Undersökningen, som genomfördes under 2008, är den hitintills mest omfattande när det gäller antalet undersökta växtskyddsmedel i svenska vattendrag. Analyserna omfattade 126 enskilda substanser, varav 39 inte undersökts tidigare inom den nationella miljöövervakningen.I undersökningen ingick provtagning i vattendrag från sex områden med betydande odling av trädgårdsgrödor. Frilandsodling av bär förekom i avrinningsområdet i SÖ Småland, grönsaker i NÖ Skåne och frukt i SÖ Skåne. Växthusodling förekom i avrinningsområdet i V Skåne och NV Skåne. I dessa områden togs ett tiotal prover per område under perioden maj-oktober 2008. Därutöver analyserades ett tjugotal vattenprover från ett av de områden som ingår i den ordinarie miljöövervakningen (område N 34 i Halland). Ett fåtal prover togs också på överskottsvatten från växthus.Totalt påträffades 78 av de 126 substanser som ingick i undersökningen, med en spridning på mellan 24 och 44 substanser i vatten från de enskilda områdena. Flest substanser och högre halter påträffades i området med intensiv grönsaksodling i NÖ Skåne, från området i Halland och från de två områdena med växthusodling. Lägre halter och färre substanser återfanns i vatten från området i SÖ Småland med odling av jordgubbar och från området i SÖ Skåne med äppelodlingar.Riktvärdet överskreds i flertalet prov som samlades in från området i NÖ Skåne och i samtliga prov från de två växthusområdena (V Skåne och NV Skåne), med högst överskridanden i de två sistnämnda områdena. Insektsmedlet imidakloprid var den substans som oftast återfanns över riktvärdet i denna undersökning. Vissa av de substanser som påträffades i förhöjda halter i vatten från områden med växthusodling återfanns också i de prover som togs på överskottsvatten från växthus. Även substanser med en betydande användning i prydnadsväxtodling i växthus påträffades i vattendraget i V Skåne. Resultaten visar att det finns läckage av växtskyddsmedel från svenska växthus. Arbete med att identifiera möjliga riskmoment i samband med växtskyddsarbete i växthus, i syfte att minska förlusterna av växtskyddsmedel till omgivande vatten, bör därför vidareutvecklas.

Significant and persistent impact of timber harvesting on soil microbial communities in Northern coniferous forests

Tidskriftsartikel (refereegranskat)abstract
- Forest ecosystems have integral roles in climate stability, biodiversity and economic development. Soil stewardship is essential for sustainable forest management. Organic matter (OM) removal and soil compaction are key disturbances associated with forest harvesting, but their impacts on forest ecosystems are not well understood. Because microbiological processes regulate soil ecology and biogeochemistry, microbial community structure might serve as indicator of forest ecosystem status, revealing changes in nutrient and energy flow patterns before they have irreversible effects on long-term soil productivity. We applied massively parallel pyrosequencing of over 4.6 million ribosomal marker sequences to assess the impact of OM removal and soil compaction on bacterial and fungal communities in a field experiment replicated at six forest sites in British Columbia, Canada. More than a decade after harvesting, diversity and structure of soil bacterial and fungal communities remained significantly altered by harvesting disturbances, with individual taxonomic groups responding differentially to varied levels of the disturbances. Plant symbionts, like ectomycorrhizal fungi, and saprobic taxa, such as ascomycetes and actinomycetes, were among the most sensitive to harvesting disturbances. Given their significant ecological roles in forest development, the fate of these taxa might be critical for sustainability of forest ecosystems. Although abundant bacterial populations were ubiquitous, abundant fungal populations often revealed a patchy distribution, consistent with their higher sensitivity to the examined soil disturbances. These results establish a comprehensive inventory of bacterial and fungal community composition in northern coniferous forests and demonstrate the long-term response of their structure to key disturbances associated with forest harvesting.

On Sustainability of Biomass for Energy and the Governance Thereof
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Due to concerns about climate change, energy security, and resource scarcity, non- renewable resources are increasingly being displaced by biomass. As with most human activities, the production of biobased products can be associated with negative impacts. Primarily, this relates to the biomass supply systems, i.e., agriculture and forestry, which currently are major causes of biodiversity loss and degradation of ecosystem services. Developing sustainable production systems when transitioning from non-renewable resources to biomass is imperative. This thesis aims to clarify the meaning of sustainability in the context of biomass for bioenergy, and contribute to our understanding of how different forms of governance can promote sustainably sourced biomass for bioenergy. The thesis is based on five appended papers: Paper I analyses to what extent, where, and under what conditions oil palm for biodiesel in Brazil can be produced profitably, and what risks and opportunities that can be associated with introducing large-scale oil palm production in Brazil. Paper II lays the foundation for understanding how new biomass production can be introduced into landscapes while supporting rather than compromising the ability of the landscape to supply other ecosystem services. Paper III describes different forms of governance and shows how these can play different roles in promoting sustainable bioenergy in different countries. Paper IV focuses on how short rotation coppice production systems are affected by EU policy and how different governance forms can assist in adapting production systems to conform to the corresponding sustainability requirements. Finally, Paper V assesses how sustainability certification (private governance) addresses biodiversity conservation and contributes to our understanding of possible improvements.

Large-scale deployment of grass in crop rotations as a multifunctional climate mitigation strategy
- 2023
-
Ingår i: GCB Bioenergy. - : Wiley. - 1757-1707 .- 1757-1693. ; 15:2, s. 166-184
-
Tidskriftsartikel (refereegranskat)abstract
- The agriculture sector can contribute to climate change mitigation by reducing its own greenhouse gas (GHG) emissions, sequestering carbon in vegetation and soils, and providing biomass to substitute for fossil fuels and other GHG-intensive products. The sector also needs to address water, soil, and biodiversity impacts caused by historic and current practices. Emerging EU policies create incentives for cultivation of perennial plants that provide biomass along with environmental benefits. One such option, common in northern Europe, is to include grass in rotations with annual crops to provide biomass while remediating soil organic carbon (SOC) losses and other environmental impacts. Here, we apply a spatially explicit model on >81,000 sub-watersheds in EU27 + UK (Europe) to explore the effects of widespread deployment of such systems. Based on current accumulated SOC losses in individual sub-watersheds, the model identifies and quantifies suitable areas for increased grass cultivation and corresponding biomass- and protein supply, SOC sequestration, and reductions in nitrogen emissions to water as well as wind and water erosion. The model also provides information about possible flood mitigation. The results indicate a substantial climate mitigation potential, with combined annual GHG savings from soil-carbon sequestration and displacement of natural gas with biogas from grass-based biorefineries, equivalent to 13%–48% of current GHG emissions from agriculture in Europe. The environmental co-benefits are also notable, in some cases exceeding the estimated mitigation needs. Yield increases for annual crops in modified rotations mitigate the displacement effect of increasing grass cultivation. If the grass is used as feedstock in lieu of annual crops, the displacement effect can even be negative, that is, a reduced need for annual crop production elsewhere. Incentivizing widespread deployment will require supportive policy measures as well as new uses of grass biomass, for example, as feedstock for green biorefineries producing protein concentrate, biofuels, and other bio-based products.

Forskningsöversikt (refereegranskat)abstract
- This research synthesis reports the main findings from a review of economic values associated with nature-based recreation in Sweden. The purpose of the work was to support policy and to identify areas for future research. Data came from over 150 scientific publications and other public sources. The authors find inter alia a lack of systematic data for several recreation activities (including naturebased tourism), a significant growth in the outdoor equipment industry and a relatively modest economic involvement by the public sector. The information is structured under different categories to illustrate the significance and range of different economic values. The authors conclude that there is a need for more comprehensive and systematically collected data, methodological development and interdisciplinary research.

The Road Towards Koster Sea National Park - Potentials and Challenges of Implementing Ecosystem Based and Participatory Maritime Management
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report provides results from a comprehensive analysis of the process leading towards Koster Sea national park, Sweden’s first marine national park. International pressure for participatory and ecosystem based management of marine resources is increasing (e.g. Convention of Biodiversity or EU’s Integrated Maritime Policy, Marine Strategy Directive, and ICZM-recommendations). Introducing integrative, participatory management of marine resources to a centralist, sector-based system of governance as in Sweden presents challenges. Various management experiments are under way. An interesting one combines protection and sustainable use in Sweden’s most valuable marine cold-water habitats: Koster Sea national park was inaugurated 2009 in parallel to the Norwegian park Ytre Hvaler and covers a large part of the archipelago and territorial waters in the municipalities of Tanum and Strömstad. The park makes an example for innovative marine management. The road towards it has been long and curvy. In the wake of proposals and protests, a process of community development with an integrative sustainability perspective has developed through an intensive dialogue between authorities and local stakeholders. After 30 years of recurring clashes locals and authorities agree that ecological and cultural values can be protected and used at the same time – under the condition that these uses are designed to be long-term sustainable, and evaluated and developed further in collaboration. Top-down management has met bottom-up initiative. Conservation is no more seen as a dead end by the users but as providing potential for rural development with sustainable tourism. The park’s goals include conservation, education, and sustainable use. Locals are not merely tolerated but an important part in the park's co-management structure – the steering committee Koster Sea Delegation and its working groups. Many participants are interested in analysing this process, which they call the ”Koster Sea Dialogue” in order to learn from it. The participation-process has been documented by the project “The Road Towards Koster Sea National Park”, financed by the Swedish Environmental Protection Agency. The study focused on the process, its drivers, the institutional framework, participation, stakeholders’ roles and networks, and conflict management. Methods include semi-structured interviews, observation and document analysis. An important process characteristic has been the long-term, active involvement of those living and working in the area. Local perspectives and knowledge have reached authorities to a larger extent than usual, making solutions adapted to local circumstances. Another characteristic is a linking of fisheries and local socio-economic development with conservation. The use of a rural development perspective, an evolving collaboration over years and active individuals at many levels have been important too. Researchers at the local marine research station have been important knowledge bearers and defenders of conservation but also translators and mediators in clashes between conservation and use. Other, more “usual” factors have been political interest, time, and resources. However, delegating the responsibility for a participation process to locals and letting it develop ad-hoc has its challenges. In rural areas it is important to proceed with care. Here, individuals are a main driving force – on leisure time. It cannot be expected from all to have the skills and resources for process leadership. People depend on each other and may be reluctant to confront neighbors. Conflicts easily become destructive if escalated. Locally based, ad-hoc process management allows for adaptation to local needs but is less transparent for outsiders. Continuous collaboration over years builds trust among those involved. On the flip side, an insider-elite with access to knowledge but little time to work with outreach may unintentionally be excluding others. Even if delegated to local forces, such processes require authorities’ back up with financial and other resources. The planning is concluded; implementation has just begun. Assessing the process from an adaptive co-management and ecosystem approach perspective – using criteria such as integration along various dimensions, adaptation and learning, participation, and a sustainable development perspective integrating ecological limits with socio-economic needs – the process and its institutional arrangements score relatively high. Some things need to be developed further: • A larger scale marine planning perspective including uses and environment in the surroundings. • The management system with working groups and the roles of the Delegation. • An more structured communication and participation planning and readiness for conflict management. • Monitoring effects in all three dimensions of sustainable development: ecological, social, economic. • Developing structures for organizational learning.

Producing Feedstock for Biofuels : Land-Use and Local Environmental Impacts
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Feedstock production and conversion to biofuels can affect the local environment in many different ways. Given that biofuels presently mostly are produced from conventional food crops, impacts resemble those characterising the present day agriculture. These depend on the crops produced, the production systems employed, governance conditions, and local environmental conditions. In the main report, production system characteristics and current documented environmental impacts related to e.g. air and water quality and biodiversity – associated with the production of relevant biofuel crops are presented in each country land-use profile

Precautionary Principle

Ingår i: International Encyclopedia of Ethics. - Chichester : Blackwell. - 9781444367072 ; , s. 4031-4039
-
Bokkapitel (refereegranskat)abstract
- Following the statement in the United Nations' Rio Declaration of 1992 that countries should apply a “precautionary approach” in policymaking on environmental and technological issues, the notion of a precautionary principle (PP) has gained ground in worldwide policymaking and regulation, thus catching the interest of ethics scholars. Although seldom explained in much detail, and resulting in quite different policy results in different countries and areas (O'Riordan et al. 2001; Sandin 1999; Trouwborst 2002; Zander 2010), PP is generally understood as a norm urging or permitting policymakers to take preventive action in the face of unknown, uncertain, or probable dangers, motivated by the experience of how seemingly valuable and promising practices may lead to seriously adverse consequences in spite of lack of solid evidence to this effect (Sandin 1999). In ethics debate, this idea has been applied not only to matters regarding the large-scale introduction and use of technology (e.g., regarding energy production, transport and communication, nano- or biotechnology, and so on) (see Biotechnology; Nanotechnology, Ethics of) with possible ensuing impact on the natural environment connecting to the notion of sustainability (see Sustainability), but also, for example, to abortion (see Abortion), medical genetics, embryo experimentation (see Embryo Research), the treatment of animals (see Animal Experimentation), terrorism (see Terrorism), and general research ethics (see Research Ethics) (Munthe 2011). Many of these applications advocate strong conclusions in spite of the fact that PP or its normative justification have not been made very clear. At the same time, PP has been the subject of criticism, much of which boils down to three points: lack of clarity, lack of practicality, and/or ethical implausibility. Curiously, these critical points have often been made in conjunction, in spite of the fact that a clear sense of what PP means seems necessary for backing up the other two objections.

Tidskriftsartikel (refereegranskat)abstract
- This Study investigated feed hygiene during airtight storage of non-dried barley grain under farm conditions. Microorganisms on the grain were sampled and quantified in seven Swedish firms throughout the storage period using culture dependent methods. The dominant lactic acid bacteria (LAB) and yeasts were identified by rRNA gene sequencing and moulds by morphological characterisation. Moisture content (MC) and pH of the grain were also monitored. It was difficult to obtain the optimal MC(0.30-0.45 g/g) that is necessary to initiate fermentation in the grain. Feed hygiene was maintained during storage of cereals when MC below 0.17 g/g. Intermediate MC (0.17-0.23 g/g) of the grains was conducive to mould growth, including growth of potential producers of mycotoxins, which can diminish feed safety and nutritional value. Enterobacteriaceae were found in all barleys, even at low MC, but their numbers were substantially decreased when the number of LAB was high. True fermentation of moist crimped cereal grains was only obtained on one farm with all initial barley MC of 0.3 g/g. Here, LAB reached high numbers during storage, whereas numbers of spoilage microorganisms that may reduce feed hygiene decreased considerably. However, the pH of the barley did not differ among farms. Storage stability in airtight stored barley may thus be the result of low oxygen tension, viz. airtight storage, and competition for nutrients by the microorganisms, rather than formation of lactic acid. At harvest, Enterococcus caccae dominated the LAB Population in five barleys and Lactobacillus fermentum at the remaining two. The dominant yeast species were Aureobasidium pullulans, Cryptococcus wieringae, Kazachstania aerobia and Rhodotorula glutinis. After storage, L fermentum was dominant among the LAB. The yeast species composition was highly diverse and differed among barleys. Among others, C. wieringae, Debaryomyces hansenii, K. aerobia, R. glutinis and Sporobolomyces ruberrimus were detected. This Study shows that the microbial population in airtight stored moist barley is highly diverse and not predictable. Thus, it may be necessary to influence the microbial population in the storage system by adding a starter culture.

Tidskriftsartikel (refereegranskat)abstract
- Preservation of moist crimped cereal grain is made feasible through fermentation by lactic acid bacteria. Climatic variations make it difficult to harvest at moisture contents (0.30-0.45g/g) to support optimal fermentation under practical conditions. Therefore, the yeast, Pichia anomala J121, previously found to prevent mould spoilage and improve preservation of moist grain in malfunctioning airtight silos, was added to moist crimped cereal grain stored in large plastic tubes. Freshly harvested barley grain was crimped and inoculated with P. anomala (105 colony-forming units/g grain). Due to the local weather conditions, harvest was delayed and moisture content in the cereal grain had decreased to 0.16-0.18g/g. P. anomala was inoculated into three batches of barley, each comprising 16tonnes packed into large plastic tubes. Three additional sets of plastic tubes were packed with cereal grain without addition of P. anomala. The grain tubes were left closed for 5 months, after which feeding to cattle commenced. In both the P. anomala inoculated and the control barley, the population diversity of lactic acid bacteria (LAB) was very high over the duration of storage. However, the dominant LAB shifted over the course of storage to Pediococcus pentosaceus and Lactobacillus paracasei, in inoculated and control barley, respectively. The yeast population in the inoculated barley was totally dominated by P. anomala during the entire storage period. In the control grain, the yeast population was more diverse, displaying shifts in the dominant species during storage. Pichia burtonii was the dominant species at the last sampling occasion. In P. anomala inoculated barley, numbers of naturally occurring moulds were reduced by about two log units, and the number of Enterobacteriaceae was reduced to below detection.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The term green infrastructure captures the need to conserve biodiversity and to sustain landscapes’ different ecosystem services. Maintaining green infrastructures through protected areas, management and landscape restoration requires knowledge in geography, spatial data about biophysical, anthropogenic and immaterial values, spatial comprehensive planning, and thus geographical information systems (GIS). To understand land use planning practices and planning education regarding GIS in Sweden we interviewed 43 planners and reviewed 20 planning education programmes. All planners used GIS to look at data but did not carry out spatial analyses of land covers. BSc programmes included more GIS than MSc programmes but very few taught analyses for spatial planning. As key spatial planning actors, municipalities’ barriers and bridges for improved GIS use for collaborative learning about green infrastructures are discussed. A concluding section presents examples of how GIS can support spatial planning for green infrastructures.

How does co-product handling affect the carbon footprint of milk? Case study of milk production in New Zealand and Sweden
- 2011
-
Ingår i: International Journal of Life Cycle Assessment. - : Springer Science and Business Media LLC. - 1614-7502 .- 0948-3349. ; 16:5, s. 420-430

Tidskriftsartikel (refereegranskat)abstract
- Purpose This paper investigates different methodologies of handling co-products in life cycle assessment (LCA) or carbon footprint (CF) studies. Co-product handling can have a significant effect on final LCA/CF results, and although there are guidelines on the preferred order for different methods for handling co-products, no agreed understanding on applicable methods is available. In the present study, the greenhouse gases (GHG) associated with the production of 1 kg of energy-corrected milk (ECM) at farm gate is investigated considering co-product handling. Materials and methods Two different milk production systems were used as case studies in the investigation of the effect of applying different methodologies in coproduct handling: (1) outdoor grazing system in New Zealand and (2) mainly indoor housing system with a pronounced share of concentrate feed in Sweden. Since the cows produce milk, meat (when slaughtered), calves, manure, hides, etc., the environmental burden (here GHG emissions) must be distributed between these outputs (in the present study no emissions are attributed to hides specifically, or to manure which is recycled on-farm). Different methodologically approaches, (1) system expansion (two cases), (2) physical causality allocation, (3) economic allocation, (4) protein allocation and (5) mass allocation, are applied in the study. Results and discussion The results show large differences in the final CF number depending on which methodology has been used for accounting co-products. Most evident is that system expansion gives a lower CF for milk than allocation methods. System expansion resulted in 63- 76% of GHG emissions attributed directly to milk, while allocation resulted in 85-98%. It is stressed that meat is an important by-product from milk production and that milk and beef production is closely interlinked and therefore needs to be considered in an integrated approach. Conclusions To obtain valid LCA/CF numbers for milk, it is crucial to account for by-products. Moreover, if CF numbers for milk need to be compared, the same allocation procedure should be applied. © 2011 Springer-Verlag.

The impact of various parameters on the carbon footprint of milk production in New Zealand and Sweden
- 2011

Tidskriftsartikel (refereegranskat)abstract
- The carbon footprint (CF) of milk production was analysed at the farm gate for two contrasting production systems; an outdoor pasture grazing system in New Zealand (NZ) and a mainly indoor housing system with pronounced use of concentrate feed in Sweden (SE). The method used is based on the conceptual framework of lifecycle assessment (LCA), but only for greenhouse gas (GHG) emissions. National average data were used to model the dairy system in each country. Collection of inventory data and calculations of emissions were harmonised to the greatest extent possible for the two systems. The calculated CF for 1kg of energy corrected milk (ECM), including related by-products (surplus calves and culled cows), was 1.00kg carbon dioxide equivalents (CO2e) for NZ and 1.16kg CO2e for SE. Methane from enteric fermentation and nitrous oxide emissions from application of nitrogen (as fertiliser and as excreta dropped directly on the field) were the main contributors to the CF in both countries. The most important parameters to consider when calculating the GHG emissions were dry matter intake (DMI), emission factor (EF) for methane from enteric fermentation, amount of nitrogen applied and EF for direct nitrous oxide emissions from soils. By changing one parameter at a time within 'reasonable' limits (i.e. no extreme values assumed), the impact on the total CF was assessed and showed changes of up to 15%. In addition, the uncertainty in CF estimates due to uncertainty in EF for methane from enteric fermentation and nitrous oxide emissions (from soil and due to ammonia volatilisation) were analysed through Monte Carlo simulation. This resulted in an uncertainty distribution corresponding to 0.60-1.52kg CO2e kg-1 ECM for NZ and 0.83-1.56kg CO2e kg-1 ECM for SE (in the prediction interval 2.5-97.5%). Hence, the variation within the systems based on the main EF is relatively large compared with the difference in CF between the countries. © 2011 Elsevier Ltd.

Modelling pesticide leaching under climate change: parameter vs. climate input uncertainty
- 2014

Ingår i: Hydrology and Earth System Sciences. - : Copernicus GmbH. - 1027-5606 .- 1607-7938. ; 18, s. 479-491

Tidskriftsartikel (refereegranskat)abstract
- Assessing climate change impacts on pesticide leaching requires careful consideration of different sources of uncertainty. We investigated the uncertainty related to climate scenario input and its importance relative to parameter uncertainty of the pesticide leaching model. The pesticide fate model MACRO was calibrated against a comprehensive one-year field data set for a well-structured clay soil in southwestern Sweden. We obtained an ensemble of 56 acceptable parameter sets that represented the parameter uncertainty. Nine different climate model projections of the regional climate model RCA3 were available as driven by different combinations of global climate models (GCM), greenhouse gas emission scenarios and initial states of the GCM. The future time series of weather data used to drive the MACRO model were generated by scaling a reference climate data set (1970-1999) for an important agricultural production area in south-western Sweden based on monthly change factors for 2070-2099. 30 yr simulations were performed for different combinations of pesticide properties and application seasons. Our analysis showed that both the magnitude and the direction of predicted change in pesticide leaching from present to future depended strongly on the particular climate scenario. The effect of parameter uncertainty was of major importance for simulating absolute pesticide losses, whereas the climate uncertainty was relatively more important for predictions of changes of pesticide losses from present to future. The climate uncertainty should be accounted for by applying an ensemble of different climate scenarios. The aggregated ensemble prediction based on both acceptable parameterizations and different climate scenarios has the potential to provide robust probabilistic estimates of future pesticide losses.

Attractive Systems for Bioenergy Feedstock Production in Sustainably Managed Landscapes– Contributions to the Call
- 2019
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Task 43 launched an initiative to identify attractive examples of landscape management and design for bioenergy and the bioeconomy. The aim of this initiative to catalogue and highlight world-wide examples of biomass production systems, throughout all stages of production, that can contribute positively to biodiversity and the generation of other ecosystem services. Information about biomass production systems and their impacts, as well as information about governance and policy initiatives that encourage adoptions of solutions leading to positive outcomes are welcomed. The goal of this initiative is to compile innovative examples as a means of showcasing how the production of biomass for bioenergy can generate positive impacts in agriculture and forestry landscapes. These examples are also meant to serve as sources of inspiration that other biomass producers can use to enhance the sustainability of their own activities. All contributions that are within scope and meet the set quality requirement are included in this Report. Selected contributions will be invited to submit a manuscript for a Special Collection in the peer review journal WIREs Energy and Environment, published by Wiley.

How to analyse ecosystem services in landscapes—A systematic review
- 2017

Ingår i: Ecological Indicators. - : Elsevier BV. - 1470-160X .- 1872-7034. ; 73, s. 492-504

Forskningsöversikt (refereegranskat)abstract
- Ecosystem services (ES) is a significant research topic with diverse modelling and mapping approaches. However, the variety of approaches—along with an inconsistent terminology—cause uncertainties concerning the choice of methods. This paper identifies and qualitatively assesses methods for mapping ES in terrestrial landscapes, based on a systematic review of the scientific literature. It further aims to clarify the associated terminology, in particular the concept of landscape and landscape scale. In total, 347 cases of ES mapping were identified in the reviewed papers. Regulating and maintenance services were most commonly mapped (165), followed by cultural (85), and provisioning services (73). For individual ES, a large variation in number of mapping cases was found. This variation may either reflect the perceived importance of the ES, or that different ES can be more or less easily mapped. Overall, Logical models and Empirical models were most commonly used, followed by Extrapolation, Simulation/Process models, Data integration, and Direct mapping. Only twelve percent of all ES mapping cases were validated with empirical data. The review revealed highly diverging views on the spatial extent of landscapes in studies of ES, and that the term landscape is sometimes used rather arbitrarily.
