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.

Ten essentials for action-oriented and second order energy transitions, transformations and climate change research
- 2018

Ingår i: Energy Research and Social Science. - : Elsevier BV. - 2214-6296 .- 2214-6326. ; 40, s. 54-70

Forskningsöversikt (refereegranskat)abstract
- The most critical question for climate research is no longer about the problem, but about how to facilitate the transformative changes necessary to avoid catastrophic climate-induced change. Addressing this question, however, will require massive upscaling of research that can rapidly enhance learning about transformations. Ten essentials for guiding action-oriented transformation and energy research are therefore presented, framed in relation to second-order science. They include: (1) Focus on transformations to low-carbon, resilient living; (2) Focus on solution processes; (3) Focus on ‘how to’ practical knowledge; (4) Approach research as occurring from within the system being intervened; (5) Work with normative aspects; (6) Seek to transcend current thinking; (7) Take a multi-faceted approach to understand and shape change; (8) Acknowledge the value of alternative roles of researchers; (9) Encourage second-order experimentation; and (10) Be reflexive. Joint application of the essentials would create highly adaptive, reflexive, collaborative and impact-oriented research able to enhance capacity to respond to the climate challenge. At present, however, the practice of such approaches is limited and constrained by dominance of other approaches. For wider transformations to low carbon living and energy systems to occur, transformations will therefore also be needed in the way in which knowledge is produced and used.

A ground-validated NDVI dataset for monitoring vegetation dynamics and mapping phenology in Fennoscandia and the Kola peninsula
- 2007

Tidskriftsartikel (refereegranskat)abstract
- An NDVI dataset covering Fennoscandia and the Kola peninsula was created for vegetation and climate studies, using Moderate Resolution Imaging Spectroradiometer 16-day maximum value composite data from 2000 to 2005. To create the dataset, ( 1) the influence of the polar night and snow on the NDVI values was removed by replacing NDVI values in winter with a pixel- specific NDVI value representing the NDVI outside the growing season when the pixel is free of snow; and ( 2) yearly NDVI time series were modelled for each pixel using a double logistic function defined by six parameters. Estimates of the onset of spring and the end of autumn were then mapped using the modelled dataset and compared with ground observations of the onset of leafing and the end of leaf fall in birch, respectively. Missing and poor-quality data prevented estimates from being produced for all pixels in the study area. Applying a 5 km x 5 km mean filter increased the number of modelled pixels without decreasing the accuracy of the predictions. The comparison shows good agreement between the modelled and observed dates ( root mean square error = 12 days, n = 108 for spring; root mean square error = 10 days, n = 26, for autumn). Fennoscandia shows a range in the onset of spring of more than 2 months within a single year and locally the onset of spring varies with up to one month between years. The end of autumn varies by one and a half months across the region. While continued validation with ground data is needed, this new dataset facilitates the detailed monitoring of vegetation activity in Fennoscandia and the Kola peninsula.

Estimating net primary production for Scandinavian forests using data from Terra/MODIS
- 2007

Ingår i: Advances in Space Research. - : Elsevier. - 0273-1177 .- 1879-1948. ; 39, s. 125-130

Tidskriftsartikel (refereegranskat)abstract
- Abstract A model for estimating net primary production (NPP) across Scandinavia has benn developed. The model is based on the light-use efficiency (LUE) concept, where NPP is calculated as a product of the amount of absorbed photosynthetically active radiation (APAR) and a LUE-factor (ε) controlling the efficiency by which vegetation transforms photosynthetically active radiation (PAR) into biomass. The fractional APAR (FAPAR) is obtained by a linear transformation of 250 m normalized difference vegetation index (NDVI) data from the Moderate Resolution Imaging Spectroradiometer (MODIS). Prior to the transformation, the NDVI time series were seasonally adjusted by fitting local asymmetric Gaussian curves to the data thereby minimizing cloud contamination and other noise factors such as BRDF-related variation. The APAR is then calculated as a product of FAPAR and incident PAR, where the latter is obtained from the “Swedish Regional Climate Modelling Programme” (SWECLIM). The LUE-factor is modeled as a daily function of temperature, latitude, and day of the year (DOY). The FAPAR dataset was validated against measurements of fractional intercepted PAR (FIPAR) that were carried out at Norunda experimental site in central Sweden (60°5′N, 17°29′E) between August and October, 2001. The calculated FAPAR time series are in good agreement with the measurements. The modeled NPP is evaluated against flux measurements carried out in Norunda 1997–1999. The determination coefficients obtained when comparing modeled with measured data are R2 = 0.82 for 2000 (RMSE = 2.71 g C m−2 d−1), and R2 = 0.68 for 2001 (RMSE = 3.57 g C m−2 d−1) (time series averaged every 10th day).

Klimat-X Experiments on Energy and Climate
- 2003
-
Konferensbidrag (refereegranskat)abstract
- Climate and energy issues are part of our everyday life. Children's understanding of energy concepts and energy transformations is often insufficient. In Malmö, Sweden, a small science center, Klimat-X, tries to capture the students' fascination and interest and give them the opportunity of building their knowledge of scientific concepts concerned with energy and climate. Examples of experiments are described and the educational problems they are designed to address will be discussed. A pilot study on the influence of the experiments on students' understanding has been carried out. The students get a deeper understanding of energy chains, they see possibilities and not only problems in energy economizing and they find the experiments funny, interesting and instructive. It seems that Klimat-X could be a starting point for reflecting upon scientific issues that have an impact on decisions made in everyday life.

Drivers of changing urban flood risk : A framework for action
- 2019
-
Ingår i: Journal of Environmental Management. - : Elsevier. - 0301-4797 .- 1095-8630. ; 240, s. 47-56

Tidskriftsartikel (refereegranskat)abstract
- This study focuses on drivers for changing urban flood risk. We suggest a framework for guiding climate change adaptation action concerning flood risk and manageability in cities. The identified key drivers of changing flood hazard and vulnerability are used to provide an overview of each driver's impact on flood risk and manageability at the city level. We find that identified drivers for urban flood risk can be grouped in three different priority areas with different time horizon. The first group has high impact but is manageable at city level. Typical drivers in this group are related to the physical environment such as decreasing permeability and unresponsive engineering. The second group of drivers is represented by public awareness and individual willingness to participate and urbanization and urban sprawl. These drivers may be important and are manageable for the cities and they involve both short-term and long-term measures. The third group of drivers is related to policy and long-term changes. This group is represented by economic growth and increasing values at risk, climate change, and increasing complexity of society. They have all high impact but low manageability. Managing these drivers needs to be done in a longer time perspective, e.g., by developing long-term policies and exchange of ideas.
