This chapter examines the conceptual framework boxes and fluxes on "Institutions and governance and other indirect drivers" (Ch. 1, Fig. 1). International and EU governance of relevance for ecosystem services, biodiversity and water is presented. Policy integration, policy coherence, management regimes and stakeholder involvement is reflected upon. The chapter contributes to further understanding of the current and future challenges for sustainable use and conservation of biodiversity and ecosystem services. It provides insights in options for integrating biodiversity and ecosystem services into sustainable development strategies and provides examples of current policy conflicts, along with trade-offs and innovative governance strategies for management of natural resources. Policy-makers need to find ways to handle policy conflicts, improve integration of different stakeholders' perspectives and value dimensions including ILK in policymaking, develop new data collection methods for linking biodiversity and ecosystem services, and develop governance systems that enhance transparency, sustainability and human well-being.

Large emissions of greenhouse gases are expected to cause major environmental problems in the future. European policy makers have therefore declared that they aim to implement cost-efficient and fair policies to reduce carbon emissions. The purpose of this paper is to assess whether the cost of the EU policies for 2020 can be reduced through the inclusion of carbon sequestration as and abatement option while also equity is improved. The assessment is done by numerical calculations using a chance-constrained partial equilibrium model of the EU Emissions Trading Scheme and national effort-sharing targets, where forest sequestration is introduced as an uncertain abatement option. Fairness is evaluated by calculation of Gini-coefficients for six equity criteria to policy outcomes. The estimated Gini-coefficients range between 0.11 and 0.32 for the current policy, between 0.16 and 0.66 if sequestration is included and treated as certain, and between 0.19 and 0.38 when uncertainty about sequestration is taken into account and policy-makers wish to meet targets with at least 90 percent probability. The results show that fairness is reduced when sequestration is included and that the impact is larger when sequestration is treated as certain.

The Swedish Social Democrats' coalition with the Left Party & the Green Party seems to be a departure from the party's unique position in Swedish politics. This article analyzes the Social Democrats' transformation from a minority ruling party to a coalition-forming party among others. If the transformation implies a substantial strategic shift, what is then behind it? The change is smaller than it might seem -- the coalition idea is far from new. The option has been considered before, but has for various reasons not been realized. The change of strategy can be explained as a tactical response to new circumstances, rather than as the result of drastic rethinking. Adapted from the source document.

The first part of this report provides an overview of the history of nuclear weapons doctrine, as it evolved in parallel to the practice of warfare and war planning in the mid-1940s and subsequently as an integral element of the cold war. A distinction is made between the early development of nuclear weapons doctrine, when United States held a dominant position in the field, and the near-parity situation that ensued in the late 1960s and onwards. The second part of the report consists of an analysis of American, British, French and Russian nuclear weapons doctrine between 1991 and 2018, illustrating how a period of low tension was gradually replaced with a reinvigoration of mutual suspicion after the year 2000. A third part briefly examines recent contributions to the American scholarly debate about the utility of nuclear weapons for strategic thought in a world moving toward polycentrism, as it revisits earlier theoretical insights and challenges conventional wisdoms. The fourth and final part elicits lessons for Sweden in particular. Overall, the report demonstrates that nuclear weapons consistently have represented an integral element of managing security risks in the Western hemisphere but that domestic political and defense industry considerations play in as well. It also suggests that doctrinal adjustments mirror the major concerns of policymakers in this regard and that nuclear powers are well aware of special obligations and privileges ascribed to them by countries that lack this category of weapons. A world in which the United States wields the greatest share of this power (unipolarity) will nonetheless be quite different from one in which two countries possess roughly the same capacity (bipolarity), and yet fundamentally different from one in which three or more countries compete to gain, or sustain, an edge toward others (multipolarity). To the extent that the world is moving toward greater security competition including the dimension of nuclear power, it will inevitably be more difficult for individual states to remain on the sidelines, unless they are ready to compromise their political autonomy. In terms of options for aligning Sweden with a broader security arrangement in the near future, there are only three feasible alternatives that may offset the risk of nuclear coercion: responding within the framework of the EU, forge closer ties to NATO, or build a bilateral relationship to the United States. Each such option comes with its own set of assets and liabilities, as does remaining a passive bystander. ; Transaltantisk och europeisk säkerhet , FORBE

While authoritarian presidents prevail under heavily president-oriented constitutions throughout the post-Soviet region, democracy along parliamentary lines triumphs in Central Europe. This article discusses the constitutional pattern among the post-communist countries on the basis of two general questions: First, how can we explain why strong presidential constitutions dominate throughout the post-Soviet region whereas constrained presidencies and governments anchored in parliament have become the prevailing option in Central Europe? Second, and interlinked with the first question, why have so many post-communist countries (in the post-Soviet region as well as in Central Europe) chosen neither parliamentarism nor presidentialism, but instead semi-presidential arrangements whereby a directly elected president is provided with considerable powers and coexists with a prime minister? The analysis indicates that both historical-institutional and actor-oriented factors are relevant here. Key factors have been regime transition, pre-communist era constitutions and leaders, as well as short-term economic and political considerations. With differing strengths and in partly different ways, these factors seem to have affected the actors' preferences and final constitutional compromises.

Groundwater monitoring is recommended as a higher-tier option in the regulatory groundwater assessment of crop protection products in the European Union. However, to date little guidance has been provided on the study designs. The SETAC EMAG-Pest GW group (a mixture of regulatory, academic, and industry scientists) was created in 2015 to establish scientific recommendations for conducting such studies. This report provides recommendations for study designs and study procedures made by the Society of Environmental Toxicology and Chemistry (SETAC) Environmental Monitoring Advisory Group on Pesticides (EMAG-Pest). Because of the need to assess the vulnerability to leaching in both site selection and extrapolating study results, information on assessing vulnerability to leaching is also a major topic in this report. The design of groundwater monitoring studies must consider to which groundwater the groundwater quality standard is applicable and the associated spatial and temporal aspects of its application, the objective of the study, the properties of the active substance and its metabolites, and site characteristics. This limits the applicability of standardised study designs. The effect of the choice of groundwater to which the water quality guideline is applied on study design is illustrated and examples of actual study designs are presented.

A food system includes many processes and actors that interact at different levels to maintain human` access to food. As the need for the food increases due to population growth, the activities associated with obtaining the food led to pressure on the environment. Climate change, nitrogen and phosphorus flows, ocean acidification, biodiversity loss, and extinction of species are directly related to the agri-food system. Therefore, transforming food production in line with the principles of the SDGs is a major challenge for all of humanity. Aquaponics (AP) is an innovative method of food production that offers sustainability solutions and therefore may be an option for the agri-food transformation. The aim of this thesis was to understand the opportunities and barriers for AP development in Sweden and how AP may penetrate the mainstream market. A qualitative study was conducted with representatives of the Swedish agri-food system where the data was collected through semi-structured interviews and analyzed throw the theoretical lens of the multi-level perspective (MLP) and the concept of protective space. Results showed that there are possibilities as well as blocking mechanisms for the development of AP in Sweden concerning conventional fish and vegetable production. To leave the innovation space and integrate into the market, it is necessary to transform the regime by stretching the legislation and changing the norms and routine for the AP integrated system. Since the AP product fits the norms of the market and the consumers food culture, its further distribution depends on enlightenment and marketing strategies.

Nomadic pastoralism has thrived in Asia's rangelands for several millennia by tracking seasonal changes in forage productivity and coping with a harsh climate. This pastoralist lifestyle, however, has come under intense transformations in recent decades due to socio-political and land use changes. One example is of the high-altitude trans-Himalayan rangelands of the Jammu and Kashmir State in northern India: major socio-political reorganisation over the last five decades has significantly impacted the traditional pasture use pattern and resources. We outline the organizational transformations and movement patterns of the Rupshu pastoralists who inhabit the region. We demonstrate the changes in terms of intensification of pasture use across the region as well as a social reorganisation due to accommodation of Tibetan refugees following the Sino-Indian war in 1961 to 1962. We focus in particular on the Tso Kar basin - an important socio-ecological system of livestock herding and biodiversity in the eastern Ladakh region. The post-war developmental policies of the government have contributed to these modifications in traditional pasture use and present a threat to the rangelands as well as to the local biodiversity. In the Tso Kar basin, the number of households and livestock has almost doubled while pasture area has declined by half. These changes have potentially negative consequences for the long-term resilience of nomadic pastoralism as well as for the survival of rare local wildlife. To increase the pastoralist standard of living, having fewer pastoralists may be the only solution, and alternative livelihood options may bring this about. Development programmes should concentrate on enhancing opportunities for herders so that there is a greater diversity of employment opportunities and potentially better chances for the persistence of biodiversity.

There is no doubt now that energy is fundamental to our development. Global energy trends such as higher energy demand and prices, big differences across regions, structural changes in an oil and gas industry increasingly dominated by national companies, the prospect of irreversible climate change, as well as demand for energy security all highlight the need for a rapid transition to a low-carbon, efficient and environmentally benign energy system. The search for energy alternatives involving locally available and renewable resources is one of the main concerns of governments, scientists and business people worldwide. As researchers tackle problems according to global trends, an overwhelming body of research focusing on bioenergy in relation to other types of renewable energy might illustrate the role bioenergy has as the most important renewable energy source for the near and medium-term future. Thus, analyzing the amount of existing research, we found that about 50% (4,911 records) of 9,724 renewable energy records available were bioenergy records. We also found that publications on each of the four main sources of biomass (agriculture, forest, waste and other) represent about one quarter of the 4,911 bioenergy records retrieved. Biomass – the fourth largest energy source after coal, oil and natural gas - is the largest and most important renewable energy option at present and can be used to produce different forms of energy. As a result, it is, together with the other renewable energy options, capable of providing all the energy services required in a modern society, both locally and in most parts of the world. Renewability and versatility are, among many other aspects, important advantages of biomass as an energy source. Moreover, compared to other renewables, biomass resources are common and widespread across the globe. The sustainability potential of global biomass for energy is widely recognized. For example, the annual global primary production of biomass is equivalent to the 4,500 EJ of solar energy captured each year. About 5% of this energy, or 225 EJ, should cover almost 50% of the world's total primary energy demand at present. These 225 EJ are in line with other estimates which assume a sustainable annual bioenergy market of 270 EJ. However, the 50 EJ biomass contributed to global primary energy demand of 470 EJ in 2007, mainly in the form of traditional non-commercial biomass, is only 10% of the global primary energy demand. The potential for energy from biomass depends in part on land availability. Currently, the amount of land devoted to growing energy crops for biomass fuels is only 0.19% of the world's total land area and only 0.5-1.7% of global agricultural land. Although the large potential of algae as a resource of biomass for energy is not taken into consideration in this report, there are results that demonstrate that algae can, in principle, be used as a renewable energy source. From all of these perspectives, the evidence gathered by the report leads to a simple conclusion: Biomass potential for energy production is promising. In most cases, shifting the energy mix from fossil fuels to renewables can now be done using existing technology. Investors in many cases have a reasonably short pay-back because of good availability of lowcost biomass fuels. The latter is of course dependant on local incentives, however. Overall, the future of bioenergy is also to a large extent determined by policy. Thus, an annual bioenergy supply covering global energy demand in 2050, superseding 1,000 EJ, should be possible with sufficient political support. Global production of biomass and biofuel is growing rapidly due to the increasing price of fossil fuels, growing environmental concerns, and considerations regarding the security and diversification of energy supply. There are many scenarios that predict a high potential for biomass in the future. There have also been many studies performed in recent decades to estimate the future demand and supply of bioenergy. Overall, the world's bioenergy potential seems to be large enough to meet the global energy demand in 2050. The current stock of standing forest is a large reservoir of bioenergy and in line with the theoretical potential of biomass energy. However, most of the research studies on biomass potentials ignore existing studies on demand and supply of wood, despite the extensive literature and data on the subject. Taking into account data from a variety of international sources, rough estimates of the energy production potential of woody biomass from forestry show that, in theory, the demand for wood fuel and industrial roundwood in 2050 can be met, without further deforestation, although regional shortages may occur. However, the shift in the energy mix requires much more investment in infrastructure, equipment and in some cases R&D. Moreover, a prerequisite for achieving bioenergy's substantially high potential in all regions is replacing current inefficient and low-intensive management systems with best practices and technologies.

In the face of climate change, the urgent need for sustainable food systems has brought agroforestry under the spotlight in the Global North, for its provision of ecosystem services. Despite being less known in the Danish and Swedish context, the traditional practice of managing livestock in the semi-natural pastures, similar to the cut-and-carry systems in the tropics, is undeniably a form of agroforestry system. With an agroecological perspective, the study adopted a quantitative statistical analysis, and identified the perceptions of farmers in Denmark and southern Sweden towards temperate agroforestry systems via an online survey. Moreover, the study conducted a qualitative document analysis on grey literatures to review national policies related to agroforestry under the framework of the European Union Common Agricultural Policies (CAP). The connection of motivating and discouraging factors to adopt agroforestry pointed out by the farmers were examined along with the current policies. Farmers' behaviour and attitude were further analyzed by conducting logistic regression modelling to distinguish the tendencies within Danish and Swedish farmers. The results revealed that 'animal health and welfare', 'landscape aesthetics', 'soil erosion', 'microclimate moderation', 'pollination', and 'carbon fixation' were perceived as positive factors by farmers from both Denmark and southern Sweden; while 'administrative burden' and 'regulation' were regarded as hurdles to include trees and bushes on farmlands. The study further identified the practice of organic operations and high diversity of livestock to be common indicators observed amongst farmers' positive attitude towards agroforestry, regardless of the discrepancy between attitude and behaviour amongst Danish farmers. At the policy level, Denmark offered many agroforestry-related financial support schemes, while the similar schemes in Sweden were generally more restricted in practice and options, except for the diverse and detailed schemes for semi-natural pastures. It was thus concluded that the silvopastoral systems had a great potential amongst Danish and Swedish farmers if the density restriction was withdrawn. To establish more agroforestry systems, 'pollination' and 'carbon sequestration' could also be further promoted in both regions, while 'soil conservation' and 'microclimate moderation' should be included in the Swedish financial support schemes. Other suggestions followed the two streams to increase landscape heterogeneity and to have more pollinators, fruits and berries. An interdisciplinary collaboration between agriculture and forestry policy makers, and farmers' participation in the policy-making process were further recommended.

Behovet av forskning om beslutsprocesser rörande investeringar i vägar och banor har uppmärksammats av KFB och Vägverket i slutet av 1990-talet. Denna studie lämnar sitt bidrag genom att redovisa och analysera den beslutsprocess som ledde fram till att ett mitträcke och 2+1 körfält anlades på E4 norr om Gävle. Med hjälp av dokument, pressklipp och intervjuer belyses utvecklingen från Nollvisionens etablering till projektets följder i form av nya mitträcken. Faktorer som problemformulering, sökande efter alternativ och värdering av konsekvenser redovisas. Sättet att organisera processen, externa intressenters inflytande samt deltagarnas roller, aktivitet och attitydutveckling belyses. Processen prövar och realiserar en helt ny utformning av vägar. Kunskapsprocessen står i centrum. Den gäller både undersökning av genomförbarheten, problemet att övertyga skeptiker och vinna acceptans samt upplevelsen av att ha åstadkommit en väsentlig innovation vad avser trafiksäkerhet. Studien lyfter fram både det specifika med detta fall och det allmängiltiga hos planering av vägar och därmed infrastruktur. – Behovet av vidare kunskapsutveckling avseende teoretiskt och empiriskt underlag för kunskap om beslutsprocesser belyses. ; The need for conducting research on decision-making processes as regards investments in roads and lanes has been paid attention to by the Swedish Transport and Communications Research Board (KFB) and the National Swedish Road Administration in the late 1990,s. This study delivers its contribution by accounting for and analysing the decision-making process that resulted in wire railings of central reserves being set up and 2 + 1 lanes being built on the European Highway No. 4 to the north of Gävle. By means of documents, press cuttings and interviews, light is being thrown on the development, from the establishment of the Vision Zero to the consequences of the project in the form of a new type of wire railings. Factors such as formulation of problems, search for options and assessment of consequences are accounted for. Ways and means to organise the process, external interested parties' influence and the participants' roles, activities and attitude development are highlighted. This process submits to testing an entirely new design of roads and puts it into practice. The process of acquiring experiences is in the centre of attraction. It applies to both the feasibility study, including the problem of convincing sceptics and gaining their acceptance, and the experience of achieving a substantial innovation in the road safety area. The study emphasises both the specific aspect of this case and the generally applicable with road planning and accordingly infra structure. The need for further development of know-how as to a theoretic and empiric knowledge bank of decision-making processes is additionally highlighted.

A current challenge that Sweden is handling is the amount of food loss and food waste. One way to reuse food waste efficiently is to convert it to feed for insects. Studies have shown that insects such as black soldier flies (Hermetia illucens) and yellow mealworms (Tenebrio militor) are the most promising insects to be used as feed, since they can be provided food waste. Furthermore, these insects have a high protein and amino acid content, which can compete with conventional feed. However, one challenge is the legislation, which does not allow food waste to be given to production animals, including insects. This study aimed to identify factors that affect the development of using insects as feed in poultry and pig production in Sweden. A flexible research design was used in this study, where both qualitative and quantitative data were used. An exploratory case study as a method with an abductive approach was furthermore the method choice of this study. The data gathering consisted essentially of semi-structured interviews and, secondarily, a survey. The survey was carried to collect hints of attitudes and opinions about insects as feed among potential consumers. The results showed that most of the respondents from the interviews were optimistic about transforming insects into a feed. It can possibly reduce the environmental impact connected to soy and fishmeal. The insects, black soldier fly and yellow mealworm were considered to take waste managers' role. Still, caution should be taken as to which substrate to use as feed for the insects. There were also split opinions between researchers about whether the black soldier fly or yellow mealworm is the best option for being transformed into a feed. There are concerns about using black soldier fly because it is not a domestic species. Furthermore, yellow mealworms might not be viewed as waste managers depending on how food waste is defined. Other concerns are that it will be challenging to identify and eliminate virus outbreaks from a circular system. Therefore, an essential characteristic of insects is that they function as a species barrier. The results made it clear that feed is rarely discussed in politics. Interest is required from politicians for this to end up on the political agenda. Furthermore, a large-scale production with an automated system is needed to lower the cost. The conclusions from this study are that stakeholders are optimistic about insects as feed. Environmental and social benefits, such as reduced food waste and insects' being a species barrier. Previous studies and our study show that it is mainly preferred to provide insects as feed for fish and poultry as they are part of their natural diet. Since population growth and increased prosperity are on the horizon, and poultry is prospected to be highly demanded, it can be beneficial to invest in poultry production to release pressure on future generations.

Agriculture provides the most essential service to mankind, as production of crops in sufficient amounts is necessary for food security and livelihood. This chapter examines the question of whether organic agriculture can produce enough food to meet future demand. This question relates to a moral imperative and any evaluation must therefore be based on objective scientific facts excluding ideological bias, political correctness, economic incentives or environmental opinions. The chapter begins by defining the conditions necessary for a stringent evaluation of crop yields and explains potential pitfalls. Yield data from national statistics, organic and conventional long-term experiments and comparative studies are then compiled and evaluated, followed by a discussion of the main factors behind low-yielding production. In a global perspective, the scientific literature shows that organic yields are between 25 and 50% lower than conventional yields, depending on whether the organic system has access to animal manure. The amount of manure available on organic farms is usually not sufficient to produce similar crop yields as in conventional systems and therefore green manures are commonly used. However, organic crop yields reported for rotations with green manure require correction for years without crop export from the field, which reduces average yield over the crop rotation. When organic yields are similar to those in conventional production, nutrient input through manure is usually higher than nutrient addition in conventional agriculture, but such high inputs are usually only possible through transfer of large amounts of manure from conventional to organic production. The main factors limiting organic yields are lower nutrient availability, poorer weed control and limited possibilities to improve the nutrient status of infertile soils. It is thus very likely that the rules that actually define organic agriculture, i.e. exclusive use of manures and untreated minerals, greatly limit the potential to increase yields. Our analysis of some yield-related statements repeatedly used by advocates of organic agriculture reached the following conclusions: Organic manure is a severely limited resource, unavailable in quantities sufficient for sustaining high crop yields; legumes are not a free and environmentally sound N source that can replace inorganic fertilisers throughout; and low native soil fertility cannot be overcome with local inputs and untreated minerals alone. Agricultural methods severely limiting crop yields are counter-productive. Lower organic yields require compensation through expansion of cropland – the alternative is famine. Combining expected population growth and projected land demand reveals that low-yielding agriculture is an unrealistic option for production of sufficient crops in the future. In addition, accelerated conversion of natural ecosystems into cropland would cause significant loss of natural habitats. Further improvement of conventional agriculture based on innovations, enhanced efficiency and improved agronomic practices seems to be the only way to produce sufficient food supply for a growing world population while minimising the negative environmental impact.

In this literature review, measures of reducing the ammonia (NH3) emissions from pig production are described, with focus on systems that can be used under Swedish conditions. The entire production chain with feed, housing, manure storage and application on the field is described and taken into consideration. However, in order to limit the study, the production of crops for feed is not included. As compared to many other countries, emissions of NH3 in Swedish pig production are already low, due to low protein levels in the feed, housing systems with a small excretory area, and storage of slurry outside the building. Lowering the crude protein level from 14.5 % to 12.5 % would reduce NH3 emission by 20 % from the pig house. Including fiber in the feed, leads to a shift from nitrogen in the urine towards more nitrogen in the faeces. In combination with removing the manure daily from the pig house, this might give opportunities for reducing NH3 emissions. A reduction in NH3 emission of up to 50 % might be possible. However, using fiber leads to higher methane (CH4) emissions (from animal and housing), and therefore this should be combined with biogas production. More research is needed in this field. Adding acids or salts to the feed could reduce NH3 emission by up to 40 %, while also improving feed conversion efficiency. Of course, good practice when preparing the feed must be followed. By applying multi-phase feeding and feeding according to the sex of the animals, NH3 emissions could be reduced by 5-15 %. By reducing feed spillage, offering a good environment for the pigs and maintaining good pig health, nitrogen losses could also be reduced with about 5 – 15 %. The importance of having clean pens is also discussed in this literature survey. Swedish housing systems, having a relatively high percentage of solid flooring (with some bedding) and a small excretory area in the pen, provides an opportunity for reducing NH3 emissions from the housing system. However, one prerequisite for this is that the pigs keep the pens clean, and therefore the room temperature should not be too high. This means that during hot periods, the air has to be conditioned before entering the pig house, e.g., by taking in the air via channels under the building. Removing manure daily by means of scrapers (reduction up to 40 %) and cooling the manure under the slats (reduction up to 50 %) are measures that are already implemented in Swedish pig production. The effect of air temperature, air flow and ventilation system are also discussed. Cleaning the exhaust air using bio-filters (up to 65 % reduction), bio-scrubbers (up to 70 % reduction) and chemical scrubbers (up to 96 % reduction) is also an option. By only purifying the exhaust air from the manure channels, the costs for this method can be reduced substantially. The emissions of CH4 and nitrous oxide (N2O) from the housing system are also discussed. Removal of the manure under the slats appears to reduce CH4 emission from the building. The use of deep-litter bedding may in many cases result in high N2O emissions. More research is needed in this field. Treating the manure with sulphuric acid, in combination with aeration and re-circulation in the pig house, can reduce NH3 emissions by up to 70 %. Pumping slurry between different compartments in a pig house is not allowed according to the Swedish Welfare Legislation. Therefore it is not certain that the acidification of slurry, inside the pig house, can be applied in Sweden. Anaerobic treatment of biogas production, as another treatment of manure, may not reduce NH3 emissions when storing and spreading the manure, but it results in increasing the nitrogen availability for the crops. In that way nitrogen losses can be reduced since less nitrogen has to be spread per hectare. Besides, biogas production reduces odour problems as well as emissions of green house gas (GHG) by the production of energy and lower CH4 emissions. Aerobic treatment of manure, can reduce the emissions of NH3 and GHG. However, poorly controlled aeration processes can have the opposite effect. Storage of slurry in a tank having a cover lid has been pointed out in many investigations, to be the easiest and most effective way of reducing NH3 and CH4 emissions. The straw used for fattening pigs is mainly consumed by the pigs, and it is rare that a naturally stable crust will be developed on the slurry. However, within piglet production a crust on the slurry tank is often found. This crust can cause problems when the slurry tank is covered. Technical solutions have to be developed to solve this problem. On pig farms, the main crops are cereals, and the slurry is mainly applied either in the spring during tillage work, or band spread in the early summer on growing cereals. Incorporation of the slurry, e.g., by harrowing in the spring, effectively reduces the NH3 losses if it takes place as soon as possible after spreading, preferably directly or at least within 4 hours after spreading. Another possibility is to band spread the slurry onto the growing cereals because the canopy provides a microclimate which reduces the NH3 losses, as compared to spreading on a bare field. Late application during the vegetation period or spreading before the autumn sowing, often results in lower nitrogen utilization by the plants, and thereby higher risks of nitrogen leakage. Due to interactions between different sources on a farm, reduction in NH3 emission from the individual sections of the livestock production system cannot be simply added to give the net reduction in emission from the total system. Thus a whole farm system approach is needed for devising control strategies for reducing NH3 emission. Four scenarios were evaluated in this report. Scenario 1 consists of: Reduction of the crude protein in the feed from 14.5 % to 12.5 %, relatively simple technique inside the pig house to reduce NH3 emission, covering the slurry tank and new technique when spreading manure. Scenario 2 consists of: Using biproducts from industry (16.5 % crude protein instead of 14.5 %) and cleaning of exhausting air, covering the slurry tank and new technique when spreading manure. Scenario 3 comprises conditions similar to those of Scenario 1, including high dietary feed fiber content in combination with biogas production. Scenario 4 comprises conditions similar to those of Scenario 2, including high dietary feed fiber content and in combination with biogas production. Preliminary calculations indicate that the scenarios may reduce emissions by 47-68 %. It should be pointed out that the calculations are still very uncertain. The calculations show that Scenario 3 appears to be the most effective way of reducing NH3 emissions. So the combination of using low protein feed with high fiber content together with the production of biogas appears to be a promising method for future development. Even Scenario 1, which used only simple techniques, has a significant result: lowering the protein content affects the entire chain from feed to the field. From the literature review, it can be concluded that one should consider whole farm systems when trying to reduce NH3 emissions. Having a roof on the manure storage, using band spreading together with incorporation, e.g. harrowing, within a few hours after spreading, are the most important and easiest ways of reducing NH3losses. When discussing the method of animal keeping, feeding and housing, a low protein level in the feed has a positive effect along the entire production chain, and appears to be the most effective means of reducing NH3 emissions. Using more fiber or acids/salts in the feed will reduce the NH3 emission even more. When biproducts from industry are used in the pig feed, cleaning the exhausting air from the manure channel may be an option. More research is needed before recommendations can be given.

During the spring of 2020, the corona pandemic created an entirely new context for university employees to work within. In a matter of weeks, it became customary to replace physical meetings with digital alternatives whenever possible. Conferences, seminars, meetings and doctoral thesis defences – among other activities – were moved to digital platforms. Meanwhile, many activities were either postponed or cancelled. The crisis resulted in a vast decrease in air travel and significantly reduced physical mobility. Increased digitalisation and reduced emissions from aviation were central to SLU's policies and strategies prior to the corona pandemic. A part of SLU's ambition of becoming a climate-neutral university by 2027 is to significantly reduce emissions from business trips and, since 2016, SLU is requested by the Swedish government to increase the share of digital and travel free meetings. SLU is also developing a new strategy for 2021-2025. A better understanding of the implications of increased digitalisation is highly relevant in this work. This study aims to provide a better understanding of how SLU staff members experienced the drastic reduction in travel and the increased use of digital solutions during the spring of 2020. We also want to shed light on what types of activities – that originally were intended to include a business trip – could be replaced by a digital alternative with maintained or improved quality and what activities that on the contrary were difficult or impossible to carry out using a digital alternative. In order to fulfil our aims, we conducted a mixed-methods study based on semistructured interviews and an online survey. The results from the survey indicate that a majority (83%) of the respondents have experienced that their work in general was either mainly positively affected, equal parts negatively and positively affected, or not affected at all by the decrease in business travel and increase in digital meetings. The respondents also painted a picture as to what activities that can work well and what activities that will be difficult to perform digitally after the corona crisis. Fieldwork stood out as the least suitable activity to perform digitally, as 60% of the respondents could imagine replacing 0% or 0-25% of the fieldwork with digital solutions. What stood out on the opposite side was that a vast majority thought that between 50-100% of project meetings, administrative meetings and seminars could be replaced with digital options. As for workshops, conferences, and reviews and presentation of research, the opinions varied much more. These findings also resonate with the experiences that were brought up in the interviews. Summary Some of the main findings in the interviews was that digital meetings were perceived as more efficient, but that they lacked in terms of social and creative aspects. Furthermore, informants largely agreed that brainstorming, spontaneous discussions and forming of new relationships was harder to achieve digitally. On the other hand, well-structured interactions with a clear agenda between people that had previously met in person worked excellent on digital platforms. Many informants expressed that they were surprised regarding how well the digital meetings had worked and pointed to the many benefits of replacing travel with digital solutions in terms of increased equality, accessibility, efficiency, reduced stress and reduced emissions. Looking forward, participants talked about a better mix of digital and physical activities. Many believed that some activities – for example establishing new relationships and performing fieldwork – to a larger extent than other activities require travel for maintained quality. Other types of activities – such as administrative meetings, project meetings, seminars and presentations – were considered possible to replace with digital solutions to a higher degree with maintained, or even enhanced, quality of work and life. The study concludes: * A majority of the SLU employees that participated in our study reported that it in general had worked well to replace longer business trips with digital alternatives during the spring of 2020. * Our quantitative findings illustrate that an overwhelming majority of the respondents thought that their work and research either had been mainly positively affected, equal parts positively and negatively affected, or not affected at all by them not being able to travel. * Certain types of fieldwork and data collection, as well as activities requiring spontaneous discussions and networking were experienced as the most difficult to perform digitally. * Well-structured interactions with a clear agenda and people that had previously met in person, as well as activities such as administrative meetings, project meetings and seminars, were perceived as most suited to perform digitally. * The study recommends a better mix between digital and physical meetings in a post-corona context. SLU should strategically make use of digital solutions and replace longer business trips to improve the work situation of the employees, the quality of their work in addition to reducing GHG emissions.
