Supergröda eller samhällsbörda? : En politisk-ekologisk analys av relationen mellan det svenska samhället och industrihampa (Cannabis Sativa L.) / Miracle crop or societal burden? : A political ecology analysis of the relationship between Swedish society and industrial hemp (Cannabis Sativa L.)Luthander, Tom January 2023 (has links)
The agricultural sector plays a crucial role in securing a more sustainable livelihood for the world's growing population. An expanded cultivation of multifunctional and environmentally smart crops like industrial hemp (Cannabis sativa L.) can thus be part of the solution in meeting the increasingly high demands of sustainable development. However, earlier research indicates that the global cultivation of industrial hemp is hindered, and that hemp is an underutilized resource relative to its potential benefits. During the 20th century hemp cultivation was banned in large parts of the world. Sweden lifted the ban in 2003, later than most other European countries. In 2017, Swedish hemp cultivation was by far one of the smallest in the European Union. This study thus aims to analyze the position of industrial hemp in Sweden – by using the theoretical framework of political ecology – to investigate which social and societal structures and processes that dictates the access to and the control of industrial hemp in Sweden today. A historical analysis of power relations as well as ideological and cultural contexts – with significance for the cultivation of hemp – is done to make the relationship between Cannabis sativa L. and Swedish society appear more clearly. The material for the analysis has been collected through a literature search and qualitative method using in-depth interviews with Swedish authorities and a national hemp association. The study discusses the relationship between hemp and human society, which is found to be characterized by a complex interconnectedness. Furthermore, the study shows that Swedish industrial hemp production is negatively affected by, among other things, cultivation bans, strict regulations, government controls, drug conservatism, and group as well as state conformity. Through a more progressive policy, industrial hemp is expected to become a positive contributing factor to reduced greenhouse gas emissions and to a growing fossil-free bio-based industry.

Studium biologických účinků technického konopí a jeho frakcí / Biological effects of various hemp fractionsVacková, Hana January 2017 (has links)
Cannabis is the only plant which contains cannabinoids and thanks to these compounds it has enormous potential. This thesis deals with the analysis of technical hemp. Effects of cannabinoids and methods used for cannabis analysis are discussed in the theoretical part. The experimental part includes spectrophotometric characterization of cannabis, it´s antimicrobial effects and thin layer chromatography analysis. Three sorts of Cannabis sativa L. were analyzed, namely Finola, Fedora and Kompolti. Firstly, the content of polyphenols, flavonoids and antioxidant activity in prepared tinctures were determined. Moreover, antimicrobial test were performed using disk test and turbidity determination. Gram-positive and Gram-negative bacteria and yeast organism were tested. It was found that cannabis tinctures possess good antimicrobial effects. Some of them are comparable with synthetic antibiotics. Finally, thin layer chromatography enabled visualization of cannabinoids in prepared tinctures.
