New policies in Sweden about intensive forestry and functional green infrastructure require involvement of different sectors for planning of landscapes and regions. However, Sweden has no territorial land-use planning at these spatial scales. Landowners, municipalities and regional governments work separately to implement policies about sustainability. There is thus a growing need for integrated spatial planning, and thus assessments of sustainability at local to regional levels by comparing monitoring results with norms expressed in policies. The aim of this thesis is to analyse and visualise such data using Geographic Information Systems (GIS) to enhance comprehensive spatial planning approaches for cooperation between different planning sectors. In paper I, habitat functionality was modelled for area-demanding focal species' requirements in five coarse forest types. Also clear-felling rates within and outside functional habitats for each of four forest owner categories were measured. The differences among landowner categories concerning planning for ecological values were linked to how biodiversity-friendly their policies were. Papers II and III analyses how forest management affects two endangered species, and show that GIS-based proxy variables can be used to predict occurrence of both terrestrial and aquatic focal species. Paper IV assesses how Forest Stewardship Council (FSC) contributes to biodiversity conservation in Sweden and Russia. Analyses of structural connectivity and habitat functionality show that the minimum standard in FSC set-asides is not compatible with higher levels of ambition to maintain biodiversity. Paper V explores how planners, locals and tourists perceive landscape values, and how these can be interpreted and used in spatial planning. Paper VI demonstrates a zoning approach to identify green infrastructures and areas suitable for intensive forestry. In paper VII indicators for ecological, economical and socio-cultural values were summarised to compare municipalities' sustainability. To conclude, there are large opportunities for analysing and visualising data to support integrated spatial planning about sustainability using GIS. However, there is a need for new education programs including all dimensions of sustainability in combination with use of GIS.
Sweden strives for adaptive wildlife management. With the introduction of new technologies and methodologies, adaptive management must be resilient and efficient in implementing and trying these, to truly stay adaptive. One of the most widely used technologies within Swedish wildlife management is camera traps, as they are a relatively cheap and unintrusive means of monitoring wildlife. In this report, I focus on the practical and theoretical development and implementation of camera traps. By conducting qualitative, key informant interviews with Swedish wildlife managers, I provide insight into managers' thoughts on and experiences with implementation of camera traps specifically and new technologies and methodologies more generally, and into their views on the challenges that Swedish wildlife management may face today, and in the future. The analysis revealed concerns in communication of information, knowledge, experiences, and technology uses between involved stakeholders, as well as issues in the coordination of methodological and technological development and implementation. Efficient communication and coordination are vital in maintaining a functional approach to adaptive wildlife management with fundamental knowledge amongst all stakeholders. The adaptive management framework and practical implementation needs careful work to obtain these functions. The analysis also revealed frustration amongst wildlife managers concerning the legislation around the use of new technologies. As adaptive management is reliant on a trial-and-error approach, legislation must be adapted to allow for new tools and methods to be tried in order to meet current and future management demands.
Coastal areas are crucial to numerous breeding bird species, but have undergone major changes because of anthropogenic development pressures such as altered land use and increased recreational activities. An understanding of what shapes species distribution patterns, and how human activities affect these patterns, is therefore necessary for marine management. The aim of this thesis is to investigate possible causes of spatial patterns of coastal breeding birds, and how human activities and environmental legislation affect these species. Forty eight coastal breeding bird species were surveyed in 4,646 squares of 1 × 1 km size, covering an archipelago in the Baltic Sea, on the east coast of Sweden. We classified all bird species as either specialist species, i.e. specialized coastal breeders, or as generalist species, i.e. species breeding also inland. Specialist species were found further out to sea, while generalist species were found closer to the mainland. The number of specialist and generalist species per square increased as total shoreline length increased, likely because of availability of suitable breeding habitat and feeding areas. Animal sanctuaries were significantly more effective in capturing specialist species and red-listed species than were unprotected areas, while nature reserves often were less effective compared to unprotected areas. Further, specialist species richness decreased as human shoreline exploitation such as buildings and jetties increased, while there was no significant effect on generalist species richness. Likewise, there was a higher probability of applications for exemptions from the general shore protection regulation to occur in squares with fewer specialist species. It is possible that habitats for specialist species are not appropriate for exploitation or that human disturbance make specialist species avoid exploited areas. The proportion of granted exemptions was very high (96%), and the areas they concerned were often close to previously exploited areas. Exploitation of shores is a continuous but slow process known as the cumulative effects problem or the 'tyranny of small decisions made singly', and this is difficult to tackle by environmental legislation. To conserve the breeding habitat along the shorelines in the archipelago, it is necessary to protect the shoreline against further exploitation, and appropriate management of unprotected shorelines is essential.
This thesis presents and asseses a method for participation in landscape planning and management. The method has a long-term perspective, while focusing on the interests of local stakeholders. Public participation has been recognized as a fundamental part of landscape planning and management. Through for example the European Landscape Convention's (ELC) inclusive definition of "landscape", landscape got a more democratic connotation where focus is put on people's perception of a landscape. This shift calls for more collaborative working methods requiring more and somewhat different skills from the professional planner than a traditional top-down system does. The research presented in this thesis is context-bound, and based on action-oriented working methods and approaches where citizens, planners and managers are involved in parallel. Academia, represented by researchers and students, is proposed to supplement and assist municipal authorities and the local society in collaborative planning. Methods and approaches related to awareness raising, embodied knowledge, strengthening people's relationship to their everyday landscape and identifying ways of letting local experts' voices be heard in the municipal planning process, have guided the research. All the cases presented, describe planning processes in peri-urban landscapes, at different scales with strong connection to nature reserves, changed patterns of land use, and with varying amounts of stakeholders directly related to the landscapes in question. Three cases were selected to discover, design and investigate potentials with the "connoisseur methods", and three cases were selected to test and refine the method, anchored in current municipal planning and resulting in actual plans. In this thesis 'The connoisseur method' is proposed as a way to achieve better collaborative planning. It invites a new type of expert to influence landscape development: the connoisseur is an expert in experiencing the landscape from her particular perspective, and represents the local society. The method proposed is a mix of different participatory methods used for landscape analysis as a way for the professional planner/manager to understand how the local community understands and uses different landscape features. The results of the different cases show how the process is of vital importance. A successful collaboration process is a valuable tool for learning, both locally among the connoisseurs and amongst the municipal planners and managers.
Background: Agriculture is among the relevant factors for the formation of cities and it has been an integral part of city life throughout history. Despite the increase in population growth, urban agriculture can offer a unique opportunity for improving the livelihood of individuals through the practice of growing food in urban green spaces. Nevertheless, maintaining urban green spaces as part of the urban fabric presents a unique challenge in an environment where there is a shortage of housing and urban space is limited for development. Allotment gardens might be seen as compensation for the lack of green space and private gardens in cities, especially in dense urban areas. However, due to the long waiting list for renting out, not everyone can get access to growing locally cultivated food and other benefits, especially people who are less privileged and cannot afford private gardens. Objective: The aim of this thesis, therefore, was to design a proposal for urban green space, Ekebydalen, to show how to integrate allotment gardening with other social activities. Also, as an input to the proposal, the history of allotment gardens and the theory of sustainable wellbeing was reviewed, and local public participation was investigated. Method: Literature was extensively reviewed in an attempt to identify relevant studies and better understand the context and characteristics of allotment gardens from a social and environmental context, the change in its land use, and accessibility; all in the perspective of the general development of urban agriculture and specifically in allotment movement through history in Sweden. Moreover, Site observation was conducted in a purposely selected allotment garden, Ekebydalen, Uppsala city. Also, an online and paper-based self-administered cross-sectional survey was done among 40 participants. Result: 6 different allotment gardens were observed and characterized. Based on the case study (observation), the Ekebydalen allotment garden was chosen as the main site for further pro-posal development. (60%) of the respondents in the survey were middle-aged (30 -50 years old) women (77.5%), most of them with university education (88%) and Swedish background (90%). Despite the participants has reported living in close proximity to the gardens, around a fourth of them reported having waited for more than six months. Gardening and nature interest (100%), socializing (15%), food complement (62%), and maintaining wellbeing (65%) are the motivation for renting allotment gardens. Conclusion: This thesis argues that the economic and wellbeing values of allotment gardens are perceived as highly significant compared to the social benefit that is allegedly seen less. Nevertheless, the social value can be seen as equally important if integrated as an activity with other social activities in a city, especially in urban communities that don't have enough space for gardening and are caught in their busy lives. Moreover, a design strategy was proposed to show how the allotment garden can be integrated as an activity for cultivation and recreation use (Cultivation park). This thesis has also implied that policy support, institutional recognition, and strong political will from policymakers and planners are required to bring urban agriculture into city planning for improving the quality of life for the people living and working in cities.
The policy term green infrastructure highlights the need to maintain functional ecosystems as a foundation for sustainable societies. Because forests are the main natural ecosystems in Europe, it is crucial to understand the extent to which forest landscape management delivers functional green infrastructures. We used the steep west-east gradient in forest landscape history, land ownership, and political culture within northern Europe's Baltic Sea Region to assess regional profiles of benefits delivered by forest landscapes. The aim was to support policy-makers and planners with evidence-based knowledge about the current conditions for effective wood production and biodiversity conservation. We developed and modeled four regional-level indicators for sustained yield wood production and four for biodiversity conservation using public spatial data. The western case study regions in Sweden and Latvia had high forest management intensity with balanced forest losses and gains which was spatially correlated, thus indicating an even stand age class distribution at the local scale and therefore long-term sustained yields. In contrast, the eastern case study regions in Belarus and Russia showed spatial segregation of areas with forest losses and gains. Regarding biodiversity conservation indicators, the west-east gradient was reversed. In the Russian, Belarusian, and Latvian case study regions, tree species composition was more natural than in Sweden, and the size of contiguous areas without forest loss was larger. In all four case study regions, 54-85% of the total land base consisted of forest cover, which is above critical fragmentation thresholds for forest landscape fragmentation. The results show that green infrastructures for wood production and biodiversity conservation are inversely related among the four case study regions, and thus rival. While restoration for biodiversity conservation is needed in the west, intensified use of wood and biomass is possible in the east. However, a cautious approach should be applied because intensification of wood production threatens biodiversity. We discuss the barriers and bridges for spatial planning in countries with different types of land ownership and political cultures and stress the need for a landscape approach based on evidence-based collaborative learning processes that include both different academic disciplines and stakeholders that represent different sectors and levels of governance.
The forestry and reindeer herding sectors utilize the same land in northern Sweden, and adversely affect each other's productivity. The common pool resource character of this situation has made it difficult to find ways to resolve conflicts that could threaten the two sectors' continued co-existence. A consultation procedure that was introduced to reduce conflicts does not appear to be effective, since conflicts between the two actors still occur. One reason for this failure might be found in the power distribution between forestry and reindeer herding. Earlier research has shown that a co-management system in which the allocation of power between the stakeholders is uneven is difficult to maintain in the long term. However, it is unclear just how uneven the power distribution is between the two actors in this case, and the consequences the disparity might have for the viability and stability of the management system. Focusing on the power relations within the consultation procedures, this paper explores the potential of the present institutional system to take the different interests of the stakeholders into account and to use the consultation procedures as tools for co-managing the forest resources in northern Sweden.
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.
Knowledge and valuation of ecosystem services are important components for reaching the governmental goals for improving the natural environments. Recreational fishing has more than one million practitioners nationwide.Knowledge about the fishers and their catches increases the ability to assess whether the ecosystem services are retained. In addition, it gives means for evaluating the actions for the conservation, restoration and sustainable use of oceans, lakes and rivers. Knowledge of recreational fishing is also needed in order to follow up the details in its environmental objectives relating to outdoor recreation, tourism industry and the governmental goals in the open-air policy. The EU's common fisheries policy, the Swedish environmental policy and Swedish fisheries policy all emphasize that ecosystem-based management should be implemented. Thus, there are needs for knowledge of the ecosystems which are exploited by humans. Fish populations are important components of aquatic ecosystems, and are affected by the surrounding environment, while they themselves affect the structures of the aquatic food-webs. Fishes often have regulatory functions in the ecosystems, and thereby contribute to valuable ecosystem services in addition to the more obvious services as providing food and recreation for humans. Mostly issues regarding the impacts of fishing-related activities on fish populations have been focused on commercial fishing. A widespread and intensive commercial fishing may lead to the depletion of stocks or, at worst, a collapse of the fish populations; the fish population reaching such low levels that recovery may be difficult. In recent years the knowledge of the impact of recreational fishing on aquatic systems has increased, but still the effects of recreational fishing on ecosystem are relatively poorly studied, compared to commercial fisheries. For many, it may be difficult to accept that recreational fishing may affect fish populations; each fisher/angler favour just their own fisheries without bearing in mind that although the small influence from each individual fisherman may be small, it will be significant when many fishermen harvest from the same stock. Recreational fishing and its effects on the aquatic ecosystems are often neglected in fisheries science, mainly due to the lack of data to estimate recreational fishing harvest with a sufficient resolution to calculate the effort and landings of recreational fisheries. In this report, we try to give an overall picture of the fish species needing increased knowledge in order to get an estimate of harvest in recreational fisheries and thereby the effect on fish populations. Furthermore, we also try to give a picture of international studies and finally to give examples of methods concerning how and to what extent one may conduct studies in Sweden. Our proposal is largely based on combining different surveys in specific areas that we believe can be used to scale-up the results. We suggest data collation of recreational fishing is concentrated to areas with public waters, because in other water bodies the land owner has sovereignty under the law. The focus areas we point out are those already having some data collection, both in terms of recreational fishing and environmental monitoring / stock assessment and where there are non-fishing protective areas nearby. Collection of data should not be made in all areas at every year; three areas are suggested to become intensive areas (data collection every year) and the remaining areas data collection will take place every three years - on a rolling schedule. The sampling methods we recommend are national survey (i.e. mail and telephone surveys), recording of catches in fishing tourism, voluntary catch registration of individual anglers, collection of data from fishing competitions, on-site inventory of fishing effort (e.g. count fetter and trailers), inventory of catch per effort (e.g. by creel-surveys) and fish tagging studies. For the west coast we propose one focus area, Älgöfjorden. At the coasts of Bohuslän County and the northern part of Halland County the fishing pressure is high for lobster and crab and therefore a focus area should be established in this area. We suggest that data are collected by on-site visits for inventorying fishing effort (counting numbers of pots / buoys / fishing people), combined with catch registration can return an estimates on catch per effort, and this can then be applied to a larger area. Another potential focus area is the area around Torhamn (Blekinge) which, for example, is popular area recreational fishing for pike. Torhamn is one of three national reference areas for coastal fish monitoring on the East Coast and has been monitored since 2002. It is also desirable to study aspects of fishing mortality in recreational fisheries. To our knowledge, there are no national studies that have explored the effects of catch-and-release in natural environments over long periods of time. The Bråviken Bay is a relatively limited and well-defined area having considered high recreational fishing pressure, but large time series from fish monitoring programmes are lacking. This site will give good opportunities for studying pike, pikeperch and to some extent also sea trout, data collection is suggested to take place every third year. An adjacent area is Kvädöfjärden having fish monitoring time series from 1989. Closely situated to Kvädöfjärden is Licknevarpefjärden where fishing has been prohibited since 1970. Additional areas that are of interest to follow up with some regularity are Asköfjärden, Gålö and / or Lagnö in the Stockholm archipelago. In the future it might be fruitful to shift data collection intensity between Torhamn in Blekinge and an area in Stockholm archipelago. Such decision should be based on factors like where the most practical solutions / contact network can be found. In the Gulf of Bothnia angling with nets, traps and similar gears are relatively widespread. We suggest that Långvind Bay in Gävleborg County, is an area for the study of recreational fishing in a relatively sparsely populated county and is most likely typical for large parts of the Gulf of Bothnia. Data collection is suggested to take place every year. As for the Gulf of Bothnia the recreational fishery in the Bothnian Bay are mainly targeting the whitefish, sea trout and, to some extent also perch. By monitoring the recreational fisheries in Kinnbäcksfjärden near Piteå, we hope to be able to describe the local recreational fishing patterns and then apply these values for catch per effort for most of the coastal strip of the Bothnian Bays. Recreational fishing is widespread in all of the five largest lakes in Sweden, and there is a need for data collection in all five. In Lake Vänern, Lake Vättern and Lake Mälaren there are fish monitoring data of good quality and regularity. However, in the two smallest lakes, Lake Hjälmaren and Lake Storsjön in Jämtland County, few test fishing areas and few studies regarding recreational fishing have been made. For Lake Vättern we suggest that data collection is done every year; especially the archipelago in the northern part of the lake will be an excellent area for the study of recreational fishing for pike. In the other four lakes we propose that data collection is made every third year. By studying recreational fishing - its practitioners, scope, gear-use, and harvest, it will be possible to achieve a more detailed view of how recreational fishing is done and how it varies along the Swedish coast and in the five largest lakes. Such knowledge is important for the managers of common fisheries resources and the monitoring of environmental status and evaluating the recreational goals established by the Swedish governments.
