Inventering av biologiskt kulturarv
- 2015
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Fältmanual till biologiskt kulturarv Föreliggande skrift är framför allt en fältmanual till biologiskt kulturarv (och ett urval av andra biologiska kulturbärare), en checklista med bilder och beskrivningar. Det tar också upp några aspekter på själva metodiken för inventering, kartering och tolkning. Fältmanualen omfattar de vanligaste aspekterna av biologiskt kulturarv som man kan hitta i svenska landskap från söder till norr. Listan beskriver biologiskt kulturarv huvudsakligen från nivåerna egenskaper, individer och artförekomster enligt RAÄ:s indelning.

- Shredder residue materials are produced after the removal of ferrous and non-ferrous fractions from end-of-life electronic equipment. Despite the high plastic content and metal value in the ash, high percentages of these materials are currently sent to landfills. In this study, the potential of utilising shredder residue material and other plastic-containing materials as reducing agents was studied. Plastic-containing materials were co-injected with coal into a zinc-fuming furnace in Boliden-Rönnskär smelter. The data obtained from the trial, such as the data from the chemical analysis of the slag and the steam production, are discussed. The observations indicate that plastic-containing material can replace up to 1 ton h−1 of coal without a significant decrease in the zinc reduction rate.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Which mitigation options in land-use management domeet the goals for green house gas emissions, biodiversityand water security?This report makes a systems analysis of land-use andits implications for green house gas emissions, biodiversityand water.The main conclusions are that:• Most land management strategies can meet the goalsfor biodiversity and water in an adequate way, exceptintensive forestry, although trade-offs between differentenvironmental values will be necessary.• It is important that there is an understanding of howthe prerequisite for impacts of land-use changes in achanging climate.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Fler arter än någonsin i mänsklighetens historia hotas av utrotning och den biologiska mångfalden lokalt har förändrats kraftigt i en stor del av världens ekosystem. Grundläggande förändringar behövs både i samhället och för individer, för att bromsa den negativa trenden, skriver en rad debattörer.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: In life cycle assessment (LCA) literature addressing land use impacts on biodiversity, several potential reference situations are proposed. However, the lack of guidance on how to apply the proposed reference situations fosters confusion within the topic and raises questions about implications of different reference conceptions. The purpose of this article is to contribute to an improved methodology for assessing biodiversity impacts in LCA through developing the use of reference situations in life cycle impact assessment (LCIA) models of land use. Methods: We analyze how reference situations are currently used when assessing the impacts from land use on biodiversity, as well as how such are defined and used outside LCA, specifically in biodiversity conservation. Based on this review, we provide recommendations to the LCIA research community on how to modify its use of reference situations to enable more relevant assessments of impacts on biodiversity. Results and discussion: It is shown how, in the LCA framework, the use of so-called baseline references dominates, and what shortcomings this implies, including unclear definitions of what “naturalness” and “pristine nature” represent, as well as the lack of reliable data. By contrast, biodiversity conservation, typically aiming at ensuring a favorable conservation status for biodiversity, normally uses limit and target references. These reference situations have the advantage of reflecting, often at an aggregated level, society’s preferences, and values related to biodiversity. Because of this, they also include biodiversity that is dependent on a certain level of management, as in, e.g., semi-natural pastures. This is an important aspect as much of the biodiversity highly valued today belong to this category. Conclusions: We recommend that reference situations for biodiversity in LCIA models should be developed based on biodiversity targets aligned with society’s conservation frameworks. Only measurements of deviation away from or closer to a desired reference situation make it possible for decision makers to distinguish the varying biodiversity-related costs and benefits that are associated with different production systems.
