    • The application of wood ash from biofuel sources to the forest has been suggested as a source of nutrients for trees and for restoration of acidified soils and surface waters. Studies on the effects of wood ash on aquatic organisms and ecosystems are, however, few. This study investigated the effects of wood ash (0.1 - 10 g l-1) on the freshwater moss Fontinalis antipyretica Hedw., which has previously been shown to be a sensitive test organism for assessing environmental pollution. After nine weeks of treatment with wood ash, a significant effect of enhanced stem growth was observed at the higher concentrations (1 � 10 g l-1). The concentration of wood ash was also correlated to the growth of secondary branches. Photosynthesis (oxygen evolution after 4 h of exposure to wood ash) was significantly lower in the alkaline treatments (no pH adjustment) compared to the treatments with neutral wood ash solutions (pH adjusted to 7.5). Furthermore, photosynthesis in the alkaline wood ash treatments was significantly lower compared to the control. The ratio between the optical density value before and after acidification (OD665/665a) was higher for all wood ash concentrations compared to the control. The OD665/665a values ranged from 1.52 to 1.61 and there was a difference, however not significant, between the alkaline and the neutral treatment at 10 g l-1 wood ash. This study clearly demonstrated that wood ash may be beneficial for F. antipyretica at moderate concentrations (0.5 - 5 g l-1), particularly when sudden increase in pH is avoided.

  • Effects on Motile Factors and Cell Growth of Euglena gracilis After Exposure to Wood Ash Solution : Assessment of Toxicity, Nutrient Availability and pH-Dependency
  • 2005
  • In: Water, Air and Soil Pollution. - : Springer Science and Business Media LLC. - 0049-6979 .- 1573-2932. ; 162:1-4, s. 353-368

    • Wood ash application (WAA) to the forest has been suggested as a resource of nutrients for trees and for restoration of acidified soils and surface waters. However, studies of the effects of WAA on aquatic systems are few. This study investigated the effects of wood ash (1-25 g L-1) on the unicellular flagellate Euglena gracilis, which has been proved to be a sensitive test organism for assessing environmental change. Long-term (7 days) growth studies and short-term (direct, 24 and 48 h) studies of different motile factors, using the automatic biological test system Ecotox, were conducted. The results show no indication of biotoxic effects due to wood ash (adjusted to neutral) treatments. However, when no adjustments of pH in wood ash solutions were made, inhibitory effects on motile factors and cell growth were observed at higher concentrations of wood ash (10-25 g L-1) due to high pH (> 8). In tests with pH adjusted to neutral, enhanced motility was observed. These results indicate that high concentration of WAA could affect freshwater environments.

  • Limnological effects on a first order stream after Wood Ash Application to a boreal forest catchment in Bispgården, Sweden
  • 2008
  • In: Forest Ecology and Management. - : Elsevier BV. - 0378-1127 .- 1872-7042. ; 255:1, s. 245-253
  • Journal article (peer-reviewed)abstract
    • In Sweden, whole tree harvest is common practice, possibly leading to the depletion of mineral nutrients. Furthermore, the increased use of forestry residues for heat production has caused an increasingly growing amount of by-product consisting of wood ash. Therefore, the Swedish Forest Agency has recommended wood ash application (WAA) to replace the mineral nutrients removed by whole tree harvesting, as well as a means to mitigate the acidification of boreal forests and surface waters. In a multidisciplinary study during 2003-2006 in Bispgarden (Sweden), we have investigated the limnological effects on a first order stream after WAA (conducted in 2004; 3000 kg ha-1) to a 50-ha forested catchment. In general, no significant effects on an annual basis were found for acidification parameters, such as pH, alkalinity and toxic forms of aluminum (Al). There was, however, evidence of an increased pH during the spring flood, accompanied by a simultaneous decrease in the frequency of low pH-values (<5.6). Moreover, alkalinity increased in the years 2005 and 2006 compared to that of 2003, although the increase in 2006 was not statistically different from that in 2005 or 2003. High concentrations of Al repeatedly occurred in the stream, and the WAA did not affect the frequencies of high concentrations of toxic Al forms (>50 μg 1-1). The benthic diatom community did not change as a result of the wood ash treatment and the diatom-based index IPS (Indice de PulluoSensibilité) indicated no nutrient enrichment or organic pollution of the stream water. There were, however, indices of elevated concentrations of potassium (K) in the aquatic moss Fontinalis antipyretica and in leaves from Alder (Alnus incana). We conclude that wood ash treatment of a forested catchment with the dose and form of ash applied in this study did not modify the freshwater ecosystem of a first order stream.

  • Respiration measurements can assess the fitness of Gammarus pulex (L.) after exposure to different contaminants : experiments with wood ash, cadmium and aluminum
  • 2005
  • In: Archiv für Hydrobiologie. - : Schweizerbart. - 0003-9136. ; 164:4, s. 479-491
  • Journal article (peer-reviewed)abstract
    • Wood ash application has been suggested as a means to mitigate acidification of surface waters. However little is known about the effects of wood ash to freshwater organisms. A Clark-type oxygen electrode was used to investigate the effects of wood ash, cadmium and aluminum on the respiration of the freshwater amphipod Gammarus pulex (L.). Harmful effects following wood ash addition were primarily found to be explained by elevated pH. At high concentrations (> 1 g/l) of wood ash the respiration of G. pulex decreased when no adjustment of pH was made, a response that was negatively correlated to the elevated pH (r = -0.43). An ion-related response was also detected in the pH-adjusted (pH 7) tests, although it was not statistically significant. Cadmium proved to be sublethal in the range of 0.2-0.4mg/l in a 24-h exposure. Mortality was 100% at 0.5 and 1.0mg Cd/l. No effects were detected after exposure to Al, due to the high pH (pH 7-8) of the solutions and the subsequently low concentrations of labile monomeric Al. We demonstrate that the method described in this paper could be a useful probe for the detection of sublethal concentrations of contaminants in freshwater ecosystems.

  • On the road to research municipalities : Analysing transdisciplinarity in municipal ecosystem services and adaptation planning
  • 2018
  • In: Sustainability Science. - : Springer. - 1862-4065 .- 1862-4057. ; 13:3, s. 765-784
  • Journal article (peer-reviewed)abstract
    • Transdisciplinary research and collaboration is widely acknowledged as a critical success factor for solution- oriented approaches that can tackle complex sustainability challenges, such as biodiversity loss, pollution, and climate-related hazards. In this context, city governments’ engagement in transdisciplinarity is generally seen as a key condition for societal transformation towards sustainability. However, empirical evidence is rare. This paper presents a self-assessment of a joint research project on ecosystem services and climate adaptation planning (ECOSIMP) undertaken by four universities and seven Swedish municipalities. We apply a set of design principles and guiding questions for transdisciplinary sustainability projects and, on this basis, identify key aspects for supporting university–municipality collaboration. We show that: (1) selecting the number and type of project stakeholders requires more explicit consideration of the purpose of societal actors’ participation; (2) concrete, interim benefits for participating practitioners and organisations need to be continuously discussed; (3) promoting the ‘inter’, i.e., interdisciplinary and inter-city learning, can support transdisciplinarity and, ultimately, urban sustainability and long-term change. In this context, we found that design principles for transdisciplinarity have the potential to (4) mitigate project shortcomings, even when transdisciplinarity is not an explicit aim, and (5) address differences and allow new voices to be heard. We propose additional guiding questions to address shortcomings and inspire reflexivity in transdisciplinary projects.

  • Implementing the Ecosystem Services Approach at the municipal level : a transdisciplinary project with coastal communities in south Sweden
  • 2014
  • Conference paper (other academic/artistic)abstract
    • In Sweden a unique project supported by the Swedish Environmental Protection Agency will be developed in close collaboration with coastal municipalities in Skåne, and with a coordinating role by Skåne´s Association of Local Authorities. These municipalities face a range of different environmental challenges, from areas along the eastern coast line facing problems related to the Baltic Sea, to municipalities in the Öresund region. In this study a range of different environmental conditions and related ecosystem services, from vulnerability to floods, erosion and sea level rise to strong pressure on coastal systems from urbanization will be investigated. Research questions and directions are built on cases and scenarios which are a part of the local municipality planning process. The approach will be to study the premises of implementing the Ecosystem Services (ES) in municipal planning and decision making of five coastal municipalities. The present study will analyse past decisions, present planning and future challenges for municipality development and management from the perspective of ES, with the aim of increasing our understanding of the ES concept as a tool for sustainable development. A second aim of the project is to evaluate the potential value of connecting the ES approach to ongoing climate change adaptation in the municipalities. The project will use the six-step approach developed by the Economics of Ecosystems and Biodiversity framework (TEEB) as the main conceptual frame. This approach includes the following steps: 1) Identifying and agreeing on the problem with stakeholders, 2) Identify the ES which are most relevant and pressing in municipality planning, 3) Collect and identify the information needs and the method to collect the data, 4) Assess expected changes in ES due to decision and input from society, 5) Identify policy options based on changes in ES and 6) Assess social and environmental impacts of 1-5.

  • Trends in municipal and comprehensive planning (1980-2012) from an Ecosystem Services Perspective in Southern Sweden
  • 2015
  • In: Book abstracts Eight International Ecosystem Services Partnership Conference 2015, Ecosystem Services for Nature, People, and Prosperity, 9-13 November 2015 Stellenbosch, South Africa. ; , s. 103-103
  • Conference paper (other academic/artistic)abstract
    • In Sweden a unique project supported by the Swedish Environmental Protection Agency is developed in close collaboration with seven coastal municipalities in Skåne. These municipalities face a range of different environmental challenges, from municipalities along the eastern coast line to municipalities in the western Öresund region. Research questions and approaches are built on case studies and scenarios to assess local municipality planning processes. The objective is to study the premises of implementing the use of the Ecosystem Service (ES) approach in municipal planning and decision making. This study presents a project component that focuses on the analysis of the comprehensive plans in the city of Malmö from 1980 to 2012. Interviews with staff from municipal departments were done as a complement to the collection of data from the comprehensive plans. The results show current trends in municipal and comprehensive planning from an ES perspective, i.e., the use of ES as a tool for sustainable development. The results further show that the ES concept was explicitly first found in the comprehensive plan from 2012. Implicitly, approaches for ecosystem services management and related planning changed from “land use”, “green areas” and “green space” (1980) towards “recreation” (1990) and “biological life cycle” and “biodiversity” (2000). This change indicates that the process in local municipality planning has shifted towards a more holistic view of the importance of ecosystems for a sustainable society and healthy life, which is currently further advanced via the ES concept.

  • Implementering av ekosystemtjänstbegreppet i kommunal verksamhet
  • 2017
  • Reports (other academic/artistic)abstract
    • Projektet ECOSIMP handlar om förutsättningen för att implementera begreppet ekosystemtjänst, i fortsättningen kallat EST-begreppet, i kommunerna, och undersöker bland annat hur kommunala tjänstemän och politiker ser på denna utmaning. En intervjustudie genomfördes med tjänstemän och politiker i de sju medverkande kommunerna. I en studie av Malmö stad undersöktes hur ekosystemtjänst-relaterade begrepp har integrerats i översiktsplaner och utvecklats till ett verktyg i hållbar samhällsplanering. Ett annat delprojekt handlar om miljökonsekvens-bedömningar (MKB) och behovet av metodutveckling för att integrera ekosystemtjänstansatsen i MKB, där möjligheten att integrera ekosystemtjänster i den så kallade RIAM-metoden analyserades. Projektet innehåller också en analys av arbetet med att integrera ekosystemtjänster i kommunernas klimatanpassning, så kallad ekosystembaserad klimatanpassning (EbA). Slutligen redovisas en analys av det transdisciplinära arbetssättet inom ECOSIMP-projektet. Resultaten visar att EST-begreppet idag är relativt välkänt i kommunerna och att det finns en övervägande positiv inställning till det och förhoppningar om att det ska skapa större möjlighet till miljöhänsyn. Förståelsen av begreppet behöver dock fördjupas i den kommunala verksamheten och distinktionen mellan implicit och explicit användning av EST-begreppet och den relaterade EST-ansatsen förtydligas. Ett antal hinder och möjligheter för att börja använda begreppet och för att uppnå etappmålet 2018 identifierades också. Bland annat upplevs innebörden av etappmålet 2018 som oklar, och bara en mindre del av de intervjuade i kommunerna ansåg att etappmålet skulle nås. Betydelsen av att politiker och allmänhet får kännedom om, och förståelse för, EST-begreppet betonades också. Malmö framstår som ett bra exempel på hur långsiktigt arbete för en hållbar stadsutveckling kan skapa förutsättningar att integrera ekosystemtjänster i den fysiska planeringen. Analysen av EbA i kommunerna visade att initiativ relaterade till klimatanpassning och ekosystemtjänster oftast inte är samordnade, men de skulle kunna utvecklas i den riktningen genom bättre samordning mellan kommunernas olika enheter och integrering av EbA i den långsiktiga planeringen utifrån kunskap om nutida och framtida klimatrisker. Verktyg för att värdera förändringar i EST till följd av mänsklig exploatering behövs och här föreslås en utveckling av den så kallade RIAM-metoden, som kan erbjuda ett sätt att väga in olika EST i planeringen. Den transdisciplinära analysen visar på värdet av nära samverkan mellan forskning och kommuner kring implementeringen av EST-ansatsen, men också på behovet av politiskt och ekonomiskt stöd för att frigöra tid för kommunerna att delta i sådana projekt.

  • Priority areas in municipality planning : Ecosystem services, environmental impact assessments and research areas
  • 2016
  • In: One Ecosystem. - : Pensoft Publishers. - 2367-8194. ; 1
  • Journal article (peer-reviewed)abstract
    • Background Several pressing issues face municipal planners including increased land use and climate change. Managing these issues requires a balance between different actions to accommodate citizen’s demands of ecosystem services (ES) and development projects. The implementation of ES as a new tool for assessments needs to be contrasted by research considering existing tools such as Environmental Impact Assessment (EIA). ES has been introduced as a policy tool at the governmental level but implementation at the local and regional scale is still needed; municipalities could benefit from collaboration with the research community for state of the art methods. One obstacle for implementation of ES is that it is not always easy for laymen to understand and additionally, the ES concept may be weakly supported by science. The municipalities realize that a society on its way towards sustainability takes advantage of new knowledge and that interactions with research will put them in the forefront of new scientific questions. The municipalities ask for research that takes a citizen perspective and research that prioritizes questions other than pure environmental considerations. Priorities in municipality planning are based on local conditions and rely on EIA. Many ecological indicators are already covered in EIA and this is reflected in Swedish Comprehensive Plans (SCP) documents, yet need further analysis is needed to be a part of ES. The SCPs present concepts at a policy level and rarely provide a more detailed plan of action compatible with the ES approach. New information We found that the use of ES concepts in Swedish Comprehensive Plans and in EIA is still not common and in need of further support from research and in practice. The EIA is decisive for comprehensive planning documents in the Swedish municipalities and follows standard format over time and between municipalities. ES is focused on human needs while the EIA describes place based assessments on environmental impact rather than feedback to the society by the intervention. Municipalities of south Sweden ask for research support in many different areas, for instance how to set up proper organization for implementation of ES and environmental issues, but priorities are based on their local conditions. The results shows that collaboration between stakeholders and researchers is needed which can create incentives, so that the decisions made by individuals, communities, corporations, and governments may be able to promote widely shared values compatible with ES. Researchers and municipalities who work on an operational level face many challenges in promoting greater use of the ES approach, with some of them yet to be defined. We conclude that implementation of ES could draw from lessons learned in the use of EIA. Further, it is presented that ES has the potential for greater public and stakeholder feedback into decisions as compared to EIA.
