The concept of integrated pest management (IPM) has been accepted and incorporated in public policies and regulations in the European Union and elsewhere, but a holistic science of IPM has not yet been developed. Hence, current IPM programs may often be considerably less efficient than the sum of separately applied individual crop protection actions. Thus, there is a clear need to formulate general principles for synergistically combining traditional and novel IPM actions to improve efforts to optimize plant protection solutions. This paper addresses this need by presenting a conceptual framework for a modern science of IPM. The framework may assist attempts to realize the full potential of IPM and reduce risks of deficiencies in the implementation of new policies and regulations.
Many urban trees are located on private property in residential areas, but these trees are infrequently included in urban forest strategies and plans, meaning that for most local governments, the complete urban residential tree population, its potential for supplying ecosystem services and its dynamics are unknown. This thesis examined the assessment methodologies of ecosystem services provided by trees in the attempt to provide valuable information about residential trees. The abundance of trees on individual residential properties was tested against potential decision-driving variables, collected using field work, remote sensing, questionnaire surveys and spatial property information. While residents reported positive attitudes to trees and benefits they provide, this did not necessarily result in greater tree abundance on individual properties. It was found that long-term of validation of sampling methods is required for monitoring of urban trees. Remote sensing could be seen as a reliable and non-invasive way to determine canopy cover using publicly available information in residential areas. This thesis improved understanding of residential urban trees and the ecosystem services they provide as the part of the urban forest. These assessment should include social and spatial variables influencing their development to allow residential trees to become integrated into local governance arrangement structure in order to develop informed management approaches for the entire urban forest.
Wild animals are used for research and management purposes in Sweden and throughout the world. Animals are often subjected to similar procedures and risks of compromised welfare from capture, anesthesia, handling, sampling, marking, and sometimes selective removal. The interpretation of the protection of animals used for scientific purposes in Sweden is based on the EU Directive 2010/63/EU. The purpose of animal use, irrespective if the animal is suffering or not, decides the classification as a research animal, according to Swedish legislation. In Sweden, like in several other European countries, the legislation differs between research and management. Whereas, animal research is generally well-defined and covered in the legislation, wildlife management is not. The protection of wild animals differs depending on the procedure they are subjected to, and how they are classified. In contrast to wildlife management activities, research projects have to implement the 3Rs and must undergo ethical reviews and official animal welfare controls. It is often difficult to define the dividing line between the two categories, e.g., when marking for identification purposes. This gray area creates uncertainty and problems beyond animal welfare, e.g., in Sweden, information that has been collected during management without ethical approval should not be published. The legislation therefore needs to be harmonized. To ensure consistent ethical and welfare assessments for wild animals at the hands of humans, and for the benefit of science and management, we suggest that both research and management procedures are assessed by one single Animal Ethics Committee with expertise in the 3Rs, animal welfare, wildlife population health and One Health. We emphasize the need for increased and improved official animal welfare control, facilitated by compatible legislation and a similar ethical authorization process for all wild animal procedures.
The SURE-Farm project aims to analyse, assess and improve the resilience and sustainability of farming systems in Europe. Farming systems face a whole range of social, ecological, economic and political disturbances and changes, such as sharp market fluctuations, severe weather events, climate change, new technologies, changes in consumer preferences and in governance structures and so forth, operating at a range of scales (local, regional, national and global). Some stresses on the farm system can be predicted (e.g. retirement of farmers), while other shocks are more uncertain and unpredictable (e.g. flooding, sudden price drop, illness). Project's WP2 aims to comprehensively understand farmers' risk behaviour and risk management (RM) decisions, and to develop and test RM strategies and decision support tools that farmers can use to cope with increasing economic, environmental and social uncertainties and risks. WP2 contributes to the development of RM in EU farming systems by understanding and eliciting farmers' risk perceptions and preferences; learning about farmers' adaptive behaviour; learning capacity and preferred improvements of current RM tools; designing and analysing improved strategies to deal with extreme weather; and co-creating improved RM tools and map-related institutional challenges.
Lithuania and Southern Sweden share similar natural conditions, but differ considerably in forest policies and management; thereby providing an opportune basis for comparative studies. Since the 1990s, Sweden has attempted to reduce the negative impact of its forest management on biodiversity, after decades of intensive production forestry. In contrast, Lithuania has been intensifying forestry practices associated with the post-soviet socio-economic transition. Here we assess the actual outcomes by comparing selected forest structure and composition variables known to be indicators for forest biodiversity; and estimate the prospective trends by scrutinising current forest policies and management. Our results indicate that Lithuanian forests consistently possessed higher rankings in six indices related to tree species composition, stand age, and deadwood quantities that are positively associated with forest biodiversity. The reverse is indicated by those data on stand age and tree diameter that are associated with centennial dynamics in forest utilisation intensity. With respect to policy instruments, Lithuania designates a substantially greater share of forest area to non-timber functions and legislates more severe management restrictions in forests targeting timber production. Concurrently, all estimates of forestry activities indicate more intensive forest management in Southern Sweden, including a higher share of artificial regeneration and shorter rotations. This allows concluding that, if current forest management practices persist, then an increased "biodiversity gap" may be expected between the two countries. The study concludes with discussing to what degree the identified trends are the direct product of targeted policies versus merely by-products of other factors.
The question under investigation in this dissertation is whether the management- and market-oriented reforms of public institutions in Sweden of the 1980s and 1990s have affected municipal politics in the direction of more or less conflict. The analysis takes its point of departure from Arend Lijphart's model of majoritarian versus consensus democracy. Majoritarian democracy refers to a form of democracy in which the central role of electing decision-makers and holding them accountable is emphasized. Majoritarian democracy therefore underlines the importance of conflict in politics. Consensus democracy refers to a form of democracy in which the importance of representing the preferences of political minorities, not only those of the majority, is emphasized. Consensus democracy therefore underlines the concern for consensus between political actors. In this study, four municipalities with different political majorities and reform ambitions within the county of Stockholm were chosen for comparative analysis . The study shows that the reforms in all likelihood have affected the political work in a more majoritarian direction. This applies in particular to the efforts of introducing new forms of management. The political relations have become more conflict-oriented and more coordinated or centralized within each political party and between the parties of a leftist and rightist orientation respectively. The political relations within the municipal committees have also become more conflict oriented, primarily by a more public and pronounced expression of divergent views. These results clearly strengthens the argument in Swedish debate that municipal politics is increasingly becoming more similar to national politics, where it is only the political parties in parliamentary majority that governs public administration. The results of this investigation therefore have implications on the organization of municipal politics in Sweden, as it is currently based on a more consensual form of democracy.
Following a multi-decadal decline of the European eel stock all across the continent, the EU adopted a protection and recovery plan in 2007, known as the Eel Regulation. Implementation, however, has come to a standstill: in 2015, the agreed goals had not been realised, the required protection had not been achieved, and from 2012 to 2015, no further reduction in mortality has been accomplished-while the stock is at a historical minimum. To analyse this manifest impasse, this article characterises the steering framework of the Eel Regulation as a governance problem. The Eel Problem is found to be extremely complex, due to many knowledge uncertainties and countless societal forces having an influence. The Eel Regulation divides this complexity along geographical lines, obliging national governments to implement national protection plans. This deliberate distribution of control has improved communication between countrymen-stakeholders, and has stimulated protective action in most EU Member States and elsewhere. In the absence of adequate international coordination and feedback on national plans, however, coherence is lacking and the common goals are not met. Actions and achievements have been assessed at the national level, but these assessments have not been evaluated internationally. Full geographical coverage has not been attained, nor is that plausible in future. Meanwhile, ICES' advice remained focused on whole-stock management, a conservative approach not matching the structure of the Eel Problem or the approach of the Eel Regulation. Hence, essentially localised problems (non-reporting, insufficient action) now lead to a hard fail, paralysing the whole European eel recovery plan. Here, I argue that immediate re-focusing protective actions, assessments, evaluations and advice on mortality goals and indicators, for each management area individually, will enable feedback on national protection plans, and in that way, will break the impasse.
Cirsium arvense (L.) Scop. is a troublesome weed, causing economic losses by reducing crop yield, increasing herbicide and tillage costs, and degrading soils due to increased tillage requirements. The major control method for C. arvense is herbicide application, but this poses socio-environmental and herbicide resistance risks. The European Union promotes reduced dependence and sustainable use of herbicides, combined with cultural and mechanical weed control. This thesis assessed the effects of integrated weed control on the population dynamics of C. arvense. For mechanical control, farmers are recommended to act when C. arvense is most sensitive to disturbance, i.e. at the point of minimum belowground weight, coinciding with 7-10 leaves per shoot. However, many farmers believe that this is too late. To estimate the compensation point (CP), defined as the minimum weight of the entire belowground structure of C. arvense, and identify links between initial root weight, planting depth and crop competition, three outdoor pot experiments were performed. For chemical control, farmers are recommended to spray when the majority of C. arvense shoots are 10-20 cm high. To assess the effects of timing and dose of herbicide application (MCPA), and crop competition on growth and development of C. arvense, one outdoor pot experiment and one field experiment were performed. The field experiment also assessed the effects of selective cutting. It was found that CP for C. arvense occurred before 3-leaf stage and that treatment effects were minor (<0.5 leaf stages). Depletion of planted root fragments ceased on average around leaf stage 3-4, indicating that CP occurs at early leaf stages. In the pot experiment, the strongest effect of herbicide treatment was obtained by spraying with the recommended dose in the presence of a crop when the largest C. arvense shoot had 3-4 leaves, corresponding to maximum height 13 cm and median height 6 cm. Crop competition reduced biomass, shoot height and leaf production of C. arvense regardless of herbicide dose. In the field experiment, herbicide treatment at 4-5 leaves or 8-10 leaves gave similar control effects as selective cutting. Herbicide application had a more immediate effect on growth and development of C. arvense while selective cutting depleted the below-ground structures more gradually. The results indicate that mechanical control of C. arvense should be performed earlier than previously recommended, probably before C. arvense reaches 3-4 leaves per shoot. Also early herbicide spraying seems to be as efficient as spraying later in the season.
Many natural resources have degraded and collapsed despite being managed under rigorous institutional frameworks set up to ensure rational exploitation. Path dependency of dysfunction institutions has been suggested as an explanation for such undesired outcomes. We explore the role of path dependency in natural resource management by studying a 100-year evolution of Swedish fisheries. We rely on three main types of original longitudinal data collected for the period 1914–2016: (A) policy documents, (B) government spending on management and subsidies, and (C) catch and fleet data. Our analysis contrasts the periods before and after the Swedish entrance into the European Union (1995) because this marks the year when fisheries policy became beyond the direct influence of the Swedish government. We uncover four pieces of evidence suggesting the existence of a path dependent dynamic in the pre-EU period: (1) despite increasing insights on the vulnerability of fish stocks to overexploitation, national policy goals in relation to fisheries continuously promoted incompatible goals of social and economic growth but without any reference to the sustainability of the biological resources; (2) the same policy instruments were used over long periods; (3) actor constellations within the fisheries policy subsystem were stable over time; (4) neither political regime nor macroeconomic variables and fisheries performance (industry production, oil price, landing values) could explain observed temporal variation in subsidies. We conclude that key policy actors in the pre-EU period formed an "iron triangle" and thereby prevented necessary policy changes. These national reinforcing feedbacks have been weakened since EU entrance, and the indicators for path dependency show broader involvement of stakeholders, a shift in spending, and policy goals that now explicitly address ecological sustainability.
It is well known that Sweden once had a state institute for racial biology, as well as that extensive racial research was conducted in Sweden during the first decades of the 20th century. But what actually happened to Swedish race research after the 1930s - did it just disappear? In The science that disappeared? historian Martin Ericsson conducts the first systematic survey of Swedish race research from the mid-1930s to the early 1970s. It is a story of a racial science that survived the horrors of World War II and endured longer than we might like to believe as criticism grew in the post-war period. And about the Norwegian Institute for Racial Biology, which was never shut down, but lived on in a different form and under a different name. Ericsson shows that there was not a single Swedish racial research tradition, but two. One was based on the first director of the Institute of Racial Biology, Herman Lundborg, and had clear connections to Nazism and other extreme right-wing movements. The second can be said to be based on Lundborg's successor Gunnar Dahlberg and was instead anti-Nazi and in some cases even anti-racist. But both traditions agreed that there were different human races and that it made sense to try to measure differences between them. By following the Swedish race research until the end of the 20th century, the book also raises important questions about our own time and its interest in ""origin"" and ""descent"". How fundamentally different are today's dna analyzes from the old racial research traditions? What if we risk asking the same questions as 1930s racial biology stuck with new techniques?
The current report deals with the effect of transport time and associated transport conditions on animal welfare and meat quality. The work is part of the EU EU and Animal Welfare Agency /Swedish Board of Agriculture, funded project CATRA (QLK5—1999-01507: Minimising stress inducing factors on cattle during handling and transport to improve animal welfare and meat quality: www.bt.slu.se/catra/). The project was composed of eight work packages: Baseline survey, Effect of transport time (below 14 hours and long distance more than 14 hours), Effect of vibration and motion (to be conducted both in laboratory and field conditions), Optimising pre-and post-transport handling, Air quality in the vehicles, cattle transport logistics including route optimisation, and development of control system. The purpose of the project was to gather sufficient data and to develop methods for controlling and minimizing stress inducing factors during handling and transport of cattle; develop guide-lines and recommendation for end-users, such as meat and vehicle industries and the policy makers, to improve animal welfare and meat quality on the European level. This could be fulfilled through optimization of design of handling areas, transport vehicles, and transport-associated conditions, and by promoting an IT-supported effective logistic system. Hence cattle welfare and meat quality will be improved, thereby enhancing the economic competitiveness of producers and abattoirs. As part of CATRA, this part of the project is the work done in Sweden regarding the effect of transport time, with the objective of determining the effect of transport time (up to ll hours) on animal welfare and post mortem meat quality, when cattle are transported from farms to abattoirs by commercial vehicles. The ultimate objective is to optimise transport time in relation to welfare and meat quality taking into consideration other stress inducing factors. Animals on which the experiments performed were cows, heifers, bulls and calves. Response parameters that were considered were: blood parameters (cortisol, glucose, lactate, CK,), clinical parameters (heart rate, postural stability), meat parameters (bruising score, PH-24, tenderness), and ethological parameters. Input parameters considered were parameters for loading facilities (ramps, lifts), penning systems (stocking density, social group, standing orientation, design of loading compartment), air quality (air speed, relative humidity, evenness of temperature in the compartment, level of NH3, CO2), vibration, transport time, resting time, and feeding regimes. Simultaneous and continuous measurement of heart rate, body temperature, air quality parameters, and video recording was conducted from farm to the abattoirs. Blood samples were taken before and after transport, and also during resting. The results obtained indicated that the transport and handling events are stressful for the animals as a whole, and loading and un-loading are among the most stressful events in the studied conditions. Regarding transport time, the results showed that transport time after six hours is particularly stressful for the animals when transported with usual vehicles without special equipments. In this case, it was reported a significant correlation between transport time and animal stress evaluated by physiological parameters. However, less detrimental effect of transport time on meat quality has been observed. It may therefore be concluded that transport time has influences more on animal welfare than meat quality when transported in conventional vehicles. Transport preceding and initiating conditions and processes such as keeping system, preparation, loading, planning and management, as well as unloading and lairage at the end of the transport chain are important challenges bearing various possibilities to improve welfare and meat quality. Loading and unloading facilities (such as ramp, driveways, and side-block) and quality, of floor have significant influence on both welfare and meat quality. Cattle from tied housing systems are more stressed by transport than untied cattle and there is a greater risk to develop bad carcass- and meat quality. As regard to air quality, the concentration level of ammonia and carbon dioxide increase with transport time and it occasionally passes the acceptable level when only natural ventilation is used. During the field experiment no detectable methane has been found. To prevent thermal stress, the installation of mechanical ventilation system (both for cooling and heating purposes) is recommended. The conclusions deduced from the current studies are as follows: - Transport conditions, as a whole is stressful for animals and compromise their welfare. - Loading and unloading activities are the most stress inducing factors identified using the heart rate measurements and behaviour observations - Result of the analysis of blood parameters showed that level of stress correlates with transport time. Calves are most sensitive to transport time followed by bulls, and cows are relatively less sensitive to transport length. - Transport time after six hours is stressful for the animals when transported with usual vehicles without special equipments. However, less detrimental effect of transport time on meat quality has been observed, - The evenness of temperature in the loading pens depends on season and number of stops - Concentration level of ammonia and carbon dioxide increase with transport time and it occasionally passes the acceptable level.
With the industrial revolution, the human utilization of the forest took a new turn as wood became a commercial product (Östlund & Zackrisson 2000). Since then, economical considerations have pervaded the public perspective on forest and forestry. However, the awareness of the need for sustainability in the use of the forest resource has also grown, and during the last decades other values have entered the discussion and the practice of forestry. Today, sustainable forest management (SFM) where economical, ecological and social values are all satisfied, is a core element in the development of acceptable forest management practices. Public participation is strongly related to SFM. In some industrialized countries, e.g. Canada, demands for participation in natural resource management have subsequently been incorporated into the legislation (Chambers and Beckley 2003), but in most countries there is no legal demand for participation. In Sweden for example, the only demand for participation in the Forestry Act is consultation before clear cutting in certain areas of reindeer herding. Forest certification, which is now covering extensive areas in several countries, plays an interesting role in the promotion of SFM. However, its main purpose is not public participation and the integration of social values into forestry (Angelstam et al. 2004). Internationally, there is the Aarhus Convention on Access to Information, Public Participation in Decision Making and Access to Justice in Environmental Matters. This convention has been ratified by Sweden amongst other countries, but it is difficult to make a strict interpretation of it. New approaches and methods are obviously needed in forest management planning to incorporate forest values other than timber production and to help solve conflicts of interest. There have been some attempts made by different types of projects. The Canadian Model Forest concept promotes participation in the work for SFM, and has been tried out in Sweden in the Vilhelmina Model Forest project (Svensson et al. 2004). Some of the LIFE projects sponsored by the European Union are also applications of participation with SFM as the objective; the project "Local Participation in Sustainable Forest Management based on Landscape Analysis" is a Swedish example of a LIFE project sponsored by the European Union (http://www.svo.se/minskog/templates/svo_se_vanlig.asp?id=8001, 2007-01-12). A potentially powerful tool in the work for sustainable forest management (SFM) and participation is multiple criteria decision analysis (MCDA), an approach which can make it possible to handle complex decision situations involving conflicting interests and several stakeholders. The purpose of this paper is to clarify concepts related to participation and present methods that are applicable in participatory planning. More specifically the following questions will be dealt with: • What is meant by participation? What methods and techniques are available to participatory planning processes? • What is MCDA and what phases do this approach require? In order to illuminate the state of art of participatory planning in forestry, an analysis of a number of case studies is presented.
The study conceptualizes economic forest sustainability as "the forest-related income and economic well-being sustained over time" and then compares Lithuania and Sweden at different scales. Sweden adopts a holistic perspective of the forest sector, where forestry and forest industries are perceived as a well-integrated economic branch. Forestry is expected to deliver raw material to forest industries, at the same time creating good preconditions for profitable forest management. Forest owners are given large freedom to act according to market signals and their own household needs, while the resulting intensive forest management cumulatively leads to a significant contribution to the country's welfare. Lithuania, in contrast, lacks an integrated sector perspective, forestry and forest industries being regarded as two separate realms. Private forest property rights are severely constrained by numerous legislative stipulations, leading to a significant reduction of economic value in production forests. On top of that, thirty percent of private owners face additional restrictions through forestland zoning, leading to further substantial loss of economic value. We suggest several measures for improving the economic forest sustainability in Lithuania, where a genuine national forest program could serve as a suitable bearing medium.
The population of the European eel Anguilla anguilla (L.) is in severe decline. In 2007, the European Union decided on a Regulation establishing measures for the recovery of the stock of European eel, obliging its Member States to implement a national Eel Management Plan by 2009. According to this Regulation, Member States will report to the Commission by July 2012, on the implementation of their Eel Management Plans and the progress achieved in protection and restoration. The current report provides an assessment of the eel stock in Sweden as of spring 2012, intending to feed into the coming Swedish post-evaluation reporting. In this report, the impacts on the stock are assessed - of fishing, restocking and of the mortality related to hydropower generation. Other anthropogenic actions, (climate change, pollution, spread of parasites, disruption of migration by transport, etc) probably have an impact on the stock too, but these factors are hardly quantified and no management targets have been set. For that reason, and because these factors were not included in the EU Eel Regulation, these other factors were excluded from this technical evaluation. In this report, focus is on the quantification of the biomass of silver eel escaping (actual, potential and pristine) and the mortality endured by those eels during their lifetime. The assessment is broken down on a regional basis, with different impacts dominating in different areas. For the yellow eel fishery on the West Coast, the assessment presented in the Eel Management Plan is extrapolated to most recent years. Since 2009, the fishery has been restricted severely, and as of spring 2012, it has been closed. In the coming years, this reduction in fishing mortality will lead to a recovery of the West Coast stock to the best possible status given the depleted state of the whole international stock. For the stock in inland waters, a new assessment is presented, in which the dominant contribution from past restocking is put central. Recent changes (increased quantities, shift to west-ward flowing rivers) will have a delayed effect over the coming 10-20 years. The escapement biomass is expected to decrease until 2020 and then to restore to its current (low) value. Assuming that current conditions (2011) are continued, the impact of the fishery will slowly decline, while the impact of hydropower generation will stabilise/increase, at least until 2030. For the East Coast fishery on silver eel, a new assessment indicates a low mortality on a very large stock of silver eel derived from all over the Baltic. Recent restrictions have reduced the East Coast fishery. Protective actions in the whole Baltic (and their delayed effects) will determine the future trend in the East Coast fishery. Comparing the overall status of the national Swedish eel stock to the management targets, it is concluded that 1. Criteria of the Swedish Eel Management Plan have been fulfilled almost exactly; 2. Biomass escaping is about one-fourth of pristine escapement, below the minimum target of 40% set in the EU Regulation; and 3. The 2011 anthropogenic impacts are about half the allowable maximum (according to the ICES/WGEEL post-evaluation framework, at one-fourth of pristine escapement). Following the current closure of the West Coast fishery, the impacts will reduce to one-quarter of that allowable maximum.
Key Points • Forestry cannot be thought of in isolation from its relations with other sectors and other parts of people's lives – for both the health of the forests and the well-being of forest peoples. • Forest governance and everyday management are upheld by a superstructure of gendered forest relations – invisible to mainstream forestry – that often disadvantages women as a social group. • Well-intentioned gender programmes can backfire, causing adverse effects on forests and forest peoples, if the efforts are not cognisant of context and power relations. • Constant awareness of differences among various social groups – men, women, different classes, ethnicities – and how their interests intersect differently in various forest contexts is needed for everyone's energy, creativity and motivation to contribute to sustainable forest management. • Research suggests that greater democratic governance of forests leads to better environmental outcomes. • The gender-neutral framing of some SDG goals undermines efforts towards achieving the outcomes called for in SDG 5.
