The effects of burn severity on soil properties : Infiltration rate, moisture, grain size distribution and carbon content Hälleskogsbrännan as an exampleHaddad, Ola January 2016 (has links)
This study focuses on soil hydrological parameters that are expected to be related to burn severity in forests; infiltration rate, soil moisture, grain size distribution and carbon content along a burn severity gradient in Västmanland Sweden, where a major fire occurred in 2014. Hälleskogsbrännan was divided into two burn severities: a moderate severity and a high severity, and a control area. Ten soil samples were taken for laboratory analyses at each severity level. Soil moisture and infiltration rate was measured in situ. Infiltration rates and soil moisture were highest in the most severely affected site, whereas fire effects on soil texture were insignificant. Soil organic carbon content was highest at the low fire severity site, followed by control and high severity fire sites. Inorganic carbon content followed the opposite trend. These results had clear trends but were insignificant, this call for more comprehensive sampling to separate possible confounding site effects.

Att få en plats på kartan : En etnologisk studie av skogsbranden i Västmanland 2014 / To get a place on the map : An ethnological study of the forest fire in Västmanland 2014Litborn, Julia January 2017 (has links)
The forest fire of Västmanland in 2014 had a significant cultural impact on local communities. Research is warranted to better understand the impact and process of recovery after natural disasters, as well as to discover how underlying political and cultural structures affect rescue and recovery. Thus far, any research in this area has been carried out by government-funded studies and evaluations of crisis management. This study complements that existing body of research by exploring this topic through local experiences and memories of the fire and emergency operations. The analysis builds on four theoretical perspectives: Foucault’s theory of power; phenomenology; memory theory, and theories of identity. Through these, the study examines how locals relate to the burnt landscape as well as explores how political tensions relating to Swedish countryside have gained new relevance as a result of the fire. These research results indicate that memories of the fire are characterized by chaotic rescue operations and crisis management, and that their failure generally is interpreted as a result of current political and cultural discourses defined by urban norms that for decades have disfavored infrastructure and social security in rural parts of Sweden. The research shows that favorable conditions for rural life in general are crucial for successful crisis management. From a societal perspective, the battle for resources between urban and rural areas, combined with inequality between city and countryside, is very problematic. Many crises occur in rural areas, which require security and infrastructure nationwide. The study therefore stresses the importance of active use of local knowledge in governing on local and regional as well as national levels. Diversity is not only a matter of ethnicity, gender and sexual orientation, but also includes perspectives from all generations living all over the country.
