The purpose of this study was to evaluate 10 process-based terrestrial biosphere models that were used for the IPCC fifth Assessment Report. The simulated gross primary productivity (GPP) is compared with flux-tower-based estimates by Jung etal. [Journal of Geophysical Research 116 (2011) G00J07] (JU11). The net primary productivity (NPP) apparent sensitivity to climate variability and atmospheric

Popular Abstract in Swedish De optiska egenskaperna i våra sjöar och vattendrag förändras kontinuerligt. Näringsrika sjöar blir grumliga genom algblomningar och erosion gör vattnet grumligt av lerpartiklar. De senaste årtiondena vattnet också blivit brunare genom att mer humusämnen läcker från omkringliggande mark. Både grumligt och humöst brunt vatten försämrar fiskens siktförhållande, men det skVisual conditions are changing in several different ways. Some lakes are getting turbid due to eutrophication or erosion while others are getting browner due to brownification. These two types of visual degradation results in completely different optical properties of lakes. Turbid water scatter light which degrades image quality severely while brown coloured humic water mainly absorb light making

Biogenic volatile organic compounds (BVOCs) play an important role in the chemistry of the troposphere, especially in the formation of tropospheric ozone (O3) and secondary organic aerosols (SOA). Ecosystems produce and emit a large number of BVOCs. It is estimated on a global scale that approximately 90% of annual BVOC emissions are from terrestrial sources. In this study, measurements of BVOCs w

Popular Abstract in Swedish För att vi ska kunna lösa globala problem som miljöförstöring och fattigdom är det många som menar att den privata sektorn måste involveras på ett aktivt sätt. I den här avhandlingen, som består av en introduktion och fem vetenskapliga artiklar som tidigare publicerats i internationella tidskrifter, studeras ett exempel på hur privata aktörer faktiskt redan involverats It is commonly argued that the private sector needs to become actively involved for society to stand a chance of solving the most pressing global problems. This thesis, consisting of five articles previously published in refereed journals and an introductory essay, studies one case of private actor participation in global environmental governance: the Kyoto Protocol’s Clean Development Mechanism (

Sweden has set a climate goal that emissions generated by businesses within Sweden by 2045 should be at least 85% lower than emissions in 1990. In 2017, the construction and real estate sector accounted for 19 % of Sweden's total greenhouse gas emissions. A large part of a building's climate impact occurs during the product phase. The foundation is part of a building’s design which signifi

Runt om i världen pågår en omställning av energisystem på internationell, nationell och regional nivå av en omfattning som inte noterats på många årtionden. Omställningen innebär i första hand en övergång från fossila, icke förnybara energikällor till fossilfria, förnybara sådana med huvudsakligt syfte att begränsa de antropologiska klimatförändringarna och andra negativa effekter på miljön. Den fAll around the world, energy systems are transforming at the international, national and regional level and at a rate not seen for many decades. This transformation primarily involves a transition away from fossil, non-renewable energy sources and to fossil-free, renewable ones with the primary purpose of halting the process of anthropological climate change and limiting other adverse effects on t

The problems faced by children trafficked for Domestic Work seems to be a continuing problem. Whereas states have ratified the various conventions aimed at protecting children in this field, the problem persists. Trafficking of children is usually portrayed in a way that most times&semic the children are trafficked across borders from country to country for purposes of being economically explo

Selektiv distribution är en distributionsform som innebär att de produkter som säljs inom systemet endast säljs till auktoriserade grossister och återförsäljare. De får i sin tur endast sälja till andra auktoriserade aktörer inom systemet eller till slutkund. För att bli auktoriserad ställs vanligtvis höga krav. De gäller bland annat krav på utbildad personal, försäljningsställets utformning och l

The introduction of new farming technologies, such as high-yielding varieties, has for long been regarded as one of the best strategies to increase agricultural production, and to combat poverty and food-insecurity. Since around 2005, New Rice for Africa (Nerica) is one of the main development strategies for combating such issues in Sierra Leone, and in many other African countries. Africa Rice Ce

Popular Abstract in Swedish Lars Ahlin har en central position i den svenska litteraturen. I forskningen framträder bilden av hans författarskap som ett litterärt projekt präglat av en jämlikhetsvision, ett motstånd mot språkliga, existentiella och politiska hierarkier. Det ahlinska berättandet är ett sällsynt gott exempel på hur ett litterärt projekt också kan vara etiskt bestämt. Detta samband bAs my title indicates, this dissertation is oriented towards two academic subjects: Ethics and Literature. Of late, the borderland between these two disciplines has attracted international scholarly attention. Within ethics, literary works are becoming a primary material; conversely, the study of literature has taken on ethical issues. As a result, the potentially referential character of fiction

För drygt tio år sedan infördes sluten ungdomsvård som ersättning av fängelsestraffet för lagöverträdare mellan 15 och 17 år. Tidigare var fängelse enda påföljden som fanns att tillgå för unga som gjort sig skyldiga till mycket allvarlig brottslighet. Lagstiftaren fann situationen otillfredsställande, eftersom fängelsemiljön ansågs olämplig för unga personer. Istället skulle de unga nu beredas indOver ten years ago closed institutional youth care was introduced as a substitute of the prison sentence for offenders between the ages of 15 and 17. Previously, imprisonment was the only sanction for young people who have committed serious delinquency. The legislature found the situation unsatisfactory as the prison environment was considered harmful and inappropriate for young people. The respon

Stress, Unmanageability, FOMO, and Lack of Recovery: A New Perspective on Adolescent Mental HealthToday, many of the challenges that adolescents face involve mental health issues, some of which have the potential of negatively affecting them for a long time to come. There is, however, at present a lack of a detailed account on the mental health issues experienced by adolescents in Sweden. This stu

In all times, societies have known social hierarchies and boundaries between individuals and groups with distinct social characteristics. The extent to which such hierarchies and boundaries are consequential for life outcomes and persist over time differs between societies. These changes over generations in the social structure, and the social, economical, and institutional developments that shape

Based on the Baltic Earth Assessment Reports of this thematic issue in Earth System Dynamics and recent peer-reviewed literature, current knowledge of the effects of global warming on past and future changes in climate of the Baltic Sea region is summarised and assessed. The study is an update of the Second Assessment of Climate Change (BACC II) published in 2015 and focuses on the atmosphere, lan

The Arctic is exposed to even faster temperature changes than most other areas on Earth. Constantly increasing temperature will lead to thawing permafrost and changes in the methane (CH4) emissions from wetlands. One of the places exposed to those changes is the Abisko-Stordalen Mire in northern Sweden, where climate and vegetation studies have been conducted since the 1970s. In our study, we anal

In Europe, willow (Salix spp.) trees have been used commercially since the 1980s at a large scale to produce renewable energy. While reducing fossil fuel needs, growing short rotation coppices (SRCs), such as poplar or willow, may have a high impact on local air quality as these species are known to produce high amounts of isoprene, which can lead to the production of tropospheric ozone (O3). Here

Drought is predicted to increase in the future due to climate change, bringing with it myriad impacts on ecosystems. Plants respond to drier soils by reducing stomatal conductance in order to conserve water and avoid hydraulic damage. Despite the importance of plant drought responses for the global carbon cycle and local and regional climate feedbacks, land surface models are unable to capture obs

Anthropogenic land-use change (LUC) substantially impacts climate dynamics, primarily through modifications in the surface biogeophysical (BGP) and biogeochemical (BGC) fluxes, which alter the exchange of energy, water, and carbon with the atmosphere. Despite the established significance of both the BGP and BGC effects, their relative contribution to climate change remains poorly quantified. In th

Background: Timely and safe elective health care facilitates return to normal activities for patients and prevents emergency admissions. Surgery is a cornerstone of elective care and relies on complex pathways. This study aimed to take a whole-system approach to evaluating access to and quality of elective health care globally, using inguinal hernia as a tracer condition. Methods: This was a prosp

Energi och klimatpåverkan är ständigt aktuellt i dagens samhälle. För att motverka den globala uppvärmningen har EU tagit fram klimatmål där bland annat energianvändningen ska minska med 20 % mot 1990 års nivåer år 2020. En stor andel av energianvändningen orsakas i Sverige idag av bygg- och fastighetsbranschen där byggnadsbeståndet står för ca 30 % av energianvändningen. För att klara EU:s klimEnergy use and climate impact are important topics in today’s society. To combat global warming, the EU has set a goal framework with a 20 % reduction target until 2020 for domestic energy use compared to 1990. Today, the building sector in Sweden accounts for 30 % of the domestic energy use. To achieve the goals for energy and climate set by the EU, changes are required. The Swedish parliament ha
