Implementering av ekosystemtjänstbegreppet i kommunal verksamhet
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)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.

- Understanding the responses of tundra systemsto global change has global implications. Most tundraregions lack sustained environmental monitoring and oneof the only ways to document multi-decadal change is toresample historic research sites. The International PolarYear (IPY) provided a unique opportunity for such researchthrough the Back to the Future (BTF) project (IPY project#512). This article synthesizes the results from 13 paperswithin this Ambio Special Issue. Abiotic changes includeglacial recession in the Altai Mountains, Russia; increasedsnow depth and hardness, permafrost warming, andincreased growing season length in sub-arctic Sweden;drying of ponds in Greenland; increased nutrient availabilityin Alaskan tundra ponds, and warming at mostlocations studied. Biotic changes ranged from relativelyminor plant community change at two sites in Greenland tomoderate change in the Yukon, and to dramatic increasesin shrub and tree density on Herschel Island, and in subarcticSweden. The population of geese tripled at one sitein northeast Greenland where biomass in non-grazed plotsdoubled. A model parameterized using results from a BTFstudy forecasts substantial declines in all snowbeds andincreases in shrub tundra on Niwot Ridge, Colorado overthe next century. In general, results support and provideimproved capacities for validating experimental manipulation,remote sensing, and modeling studies.

Defining potential valuables through the characterisation of lake sediments : case study in Arkelstorp bay, Sweden
- 2022

Tidskriftsartikel (refereegranskat)abstract
- This study aims to characterise and discuss the potential use of sediment from the Arkelstorp bay located in the south of Sweden. Sediments from the Arkelstorp bay is collected and analysed on nutrient content, age, and potential contaminants. No organic environmental pollutants are found and the metal content are not elevated but still problematically high. For example, the amount of cadmium per phosphorus is 480 mg Cd kg(-1) P. However, as the carbon 14-datings showed, the sediment is preindustrial. Therefore, the amount of registered cadmium comes naturally from the surrounding environment. Arkelstorp sediments present the potential to become a source of nutrition in agriculture. The results show that the material is a good source of nutrients, with a nitrogen content of 18 g kg(-1) dry matter (DM), phosphorus 0.8 g kg(-1) DM and potassium 2.4 g kg(-1) DM respectively. However, the metal content is problematic to use the material without any pre-treatment. On the other hand, bioenergy production is expected to increase in the future, where this resource could potentially be helpful for the cultivation of bioenergy crops.

Tidskriftsartikel (refereegranskat)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.

Fostering incidental experiences of nature through green infrastructure planning
- 2017

Tidskriftsartikel (refereegranskat)abstract
- Concern for a diminished human experience of nature and subsequent decreased human well-being is addressed via a consideration of green infrastructure’s potential to facilitate unplanned or incidental nature experience. Incidental nature experience is conceptualized and illustrated in order to consider this seldom addressed aspect of human interaction with nature in green infrastructure planning. Special attention has been paid to the ability of incidental nature experience to redirect attention from a primary activity toward an unplanned focus (in this case, nature phenomena). The value of such experience for human well-being is considered. The role of green infrastructure to provide the opportunity for incidental nature experience may serve as a nudge or guide toward meaningful interaction. These ideas are explored using examples of green infrastructure design in two Nordic municipalities: Kristianstad, Sweden, and Copenhagen, Denmark. The outcome of the case study analysis coupled with the review of literature is a set of sample recommendations for how green infrastructure can be designed to support a range of incidental nature experiences with the potential to support human well-being.

Tidskriftsartikel (refereegranskat)abstract
- An important task in research about natural resource management is to communicate the utility of different approaches from various settings. Using ecosystem services as a conceptual frame, we study a local solution to alleviate goose-human conflicts in an agricultural region in Sweden. Increasing goose numbers and crop damage led to the foundation of a goose management group (GMG), comprising landowners, farmers, hunters, ornithologists, conservation NGOs, and local and county level administration. The GMG was not given any formal or legal authority. We asked: is this management solution successful? Which problems can be solved and which remain? Can the GMG stand as a model for management of other species and in other landscapes? We interviewed present members of the GMG and analyzed minutes from its meetings. We found that the GMG has autonomy to self-organize and shows adaptive capacity over time in handling variability and complexity in its socio-ecological system. This makes the GMG a sustainable solution for local management of a resource in which goose population growth and legislation are decided at other (national or international) levels. We assessed what constitutes perceived success and found that GMG is geared toward mediation of opposing preferences by establishing a figurative handshake between stakeholders. By comparing how four general challenges in ecosystem service management align with formative attributes of the GMG, we discuss in which ways this management solution is applicable to other ecosystem services in other contexts.

Climate change-induced shifts in survival and size of the worlds' northernmost oviparous snake : A 68-year study
- 2024
-
Ingår i: PLoS ONE. - : Public Library of Science. - 1932-6203. ; 19:3
-
Tidskriftsartikel (refereegranskat)abstract
- Because of their dependence on ambient temperature ectothermic animals can serve as sentinels of conservation problems related to global warming. Reptiles in temperate areas are especially well suited to study such effects, as their annual and daily activity patterns directly depend on ambient temperature. This study is based on annual data spanning 68 years from a fringe population of Grass Snakes (Natrix natrix), which is the world's northernmost oviparous (egg-laying) reptile, and known to be constrained by temperature for reproduction, morphology, and behavior. Mark-recapture analyses showed that survival probability was generally higher in males than in females, and that it increased with body length. Body condition (scaled mass index) and body length increased over time, indicative of a longer annual activity period. Monthly survival was generally higher during winter (i.e., hibernation) than over the summer season. Summer survival increased over time, whilst winter survival decreased, especially duringrecent decades. Winter survival was lower when annual maximum snow depth was less than 15 cm, implying a negative effect of milder winters with less insulating snow cover. Our study demonstrates long-term shifts in body length, body condition and seasonal survival associated with a warming climate. Although the seasonal changes in survival ran in opposite directions and though changes were small in absolute terms, the trends did not cancel out, but total annual survival decreased. We conclude that effects of a warming climate can be diverse and pose a threat for thermophilic species in temperate regions, and that future studies should consider survival change by season, preferably in a long-term approach.

Implementation of the ecosystem services approach in Swedish municipal planning
- 2018

- While ecosystem-based planning approaches are increasingly promoted through international and national policies, municipalities are still struggling with translating them into practice. Against this background, this paper aims to increase the knowledge of current advances and possible ways to support the implementation of the ecosystem services (ES) approach at the municipal level. More specifically, we analyze how ES have been integrated into comprehensive planning within the municipality of Malmö in Sweden over the last 60 years, a declared forerunner in local environmental governance. Based on a content analysis of comprehensive plans over the period 1956–2014 and interviews with municipal stakeholders, this paper demonstrates how planning has shifted over time toward a more holistic view of ES and their significance for human well-being and urban sustainability. Both explicit and implicit applications of the ES concept were found in the analyzed comprehensive plans and associated programs and projects. Our study shows how these applications reflect international, national, and local policy changes, and indicates how municipalities can gradually integrate the ES approach into comprehensive planning and facilitate the transition from implicit to more explicit knowledge use.

Nitrogen uptake potential under different temperature-salinity conditions: Implications for nitrogen cycling under climate change scenarios
- 2018

Ingår i: Marine Environmental Research. - : Elsevier BV. - 0141-1136 .- 1879-0291. ; 141:October, s. 196-204

Tidskriftsartikel (refereegranskat)abstract
- As projected by climate change models, increase in sea surface temperature and precipitation in the future may alter nutrient cycling in the coastal regions due to potential changes in phytoplankton community structure and their ability to assimilate nitrogen (N) and carbon (C). An experiment simulating different temperature and salinity conditions (28 degrees C-35 ambient conditions, 28 degrees C-31, 31 degrees C-35 and 31 degrees C-31) in mesocosms containing 1000 L of coastal water from the Arabian Sea was performed and N uptake rates were measured using N-15 tracer technique on 2nd, 5th, 7th and 10th day of the experiment. The results show that, under all conditions, the total N (NO3- + NH4+) uptake rates were lower in the beginning and on the final day of the tracer experiment, while it peaked during middle, consistent with chlorophyll a concentrations. Total N uptake rate was significantly lower (p = 0.003) under ambient temperature -lower salinity condition (28 degrees C-31) than the others. This indicates that lowering of salinity in coastal regions due to excessive rainfall in the future may affect the N uptake potential of the phytoplankton, which may change the regional C and N budget.
