Slam ? en outnyttjad resurs i skogsbruket

Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.

Hälsokontrollen av den gemensamma jordbrukspolitiken (CAP) : effekter på lantbruket genom gårdsstödet

The Healthcheck is an evaluation of the 2003 years reform of the Common Agricultural Policy (CAP). When the Healthcheck of CAP is decided, most likely in the beginning of 2009, there will be a discussion about how CAP will appear in the next budget period 2013. One main question in the Healthcheck is how the farm support will be designed. A suggestion that has arised is if todays addition amount for dairy- and beef production should be transferred to the fundamental farm support. In this exam theses calculations has been done in created typical farms in every Swedish support region for cereals-, dairy- and beef production.

CAP ? pengaslukande monster eller effektiv jordbrukspolitik EU:s gemensamma jordbrukspolitik sedd ur tre olika teoretiska perspektiv

The Common Agricultural Policy has been a burning topic for debate for severaldecades. According to the CAP:s opponents it's effects include pollution, market distortionsand not least a huge expense for the European union.In this study we seek to explain why the CAP has remained almostunreformed since it's constitution in the 1950:s. The means by which we do so isa case study where we analyze the CAP by using three different theories; liberalinter-governmentalism, realistic trade theory and new institutionalism.In the final chapter we conclude that the theories complement each other. Newinstitutionalism explains the rigidity of the CAP. The liberal perspective explainsthe origin and the logic behind the policy whereas the realistic point of view putsthe policy in the light of an international economic theory and recognizes nationalpolicy makers roll in the inflexibility of the CAP..

Suitability analysis of a reintroduction of the great bustard (Otis tarda) to Sweden

The great bustard (Otis tarda) became extinct in Sweden during the mid-19th century. Globally, populations have suffered dramatic declines during the past two centuries. Recently, local populations have stabilized or increased after hunting bans and conservation efforts. Despite positive trends the species is still classified by IUCN as vulnerable (VU), mainly due to withdrawals in the distribution. The limited distribution emphasizes the need for finding ?new? areas suitable for a translocation or reintroduction.

En organisation i förändring. En fallstudie om Lantbrukarnas Riksförbund och riksförbundsstämman.

AbstractThe Swedish agricultural organisation, LRF, stands in front of many changes and the work with the changes in the organisation has caused some conflicts at the top. Is it like Michels say that it's a few people at the top that rules? The case with LRF shows to be something different, since the president Caroline Trapp was re-elected. The election committee proposed a new president, but the assembly had another opinion and re-elected Caroline Trapp. This shows that the opinions at the top were not the same as among the members of the organisation and the election committee couldn?t rule over them.In this essay I try to understand what kind of organisation LRF is and what made this case special.

Attityder till återintroduktion av visent i Sverige

The European bison is a species which is no longer present in the wild fauna of Sweden. Reintroduction has been proposed in several different forums. Reintroduction is an attempt to reestablish a viable population of a species in an area to which it is native. To make such an operation successful in the long run it is essential to know the attitudes of the stakeholders involved. This study has sensed the attitudes towards reintroduction of European bison to Sweden.

Med andras ögon : En intervjustudie av åsikter och värderingar om effekter och produkter av det svenska jordbruket

The majority of the Swedish population were self-provided within agriculture a hundred years ago. Times do change and today the situation is the other way around - most of us live within city boundaries and only few work with farming and related agricultural businesses. One thing that has not changed though, is the need of supplies from Swedish agriculture.What do we think of those products? Are we even aware of the connection between us and agriculture? The Federation of Swedish Farmers, LRF (Lantbrukarnas riksförbund), started their project to strengthen the link between consumers and producers in 2008.This paper is part of the project and its aim is to investigate consumers' views and values upon the effects and products from Swedish agriculture.Opinions and values have been studied through interviews influenced by phenomenology. The results show that the informants in general had a positive approach and thinking concerning the products and effects from Swedish agriculture.

Historisk markanvändning på Färsna gårds inägor och utmarker

Semi-natural grasslands are threatened biotopes in the landscape and without conservation measures high values of nature will be lost. Meanwhile, the biological values associated with cultural values of the traditional agricultural landscape in Sweden. Studies of land use history may help to understand how today biological diversity has evolved and how it can be preserved. Färsna farm in Norrtälje has left some of the old heritage of biological diversity in the form of nature - forest and grassland, which hosts an unusual herb-rich flora. Through the study of historic maps and från1673/1767/1801/1901 1952 and orthophoto of the area has a picture of how land use has changed over time emerged.

Organizing for value creation : a corporate perspective on urban farming

In the year 1800, about 5 % of the world population lived in cities (World Wide Fund for Nature, 2012, 3). Today that number is about 70 % in Europe and North America, and in 2050 it is expected to be 86 % in the developed world and 67 % in the developing world (www, UN, 2009). In addition, the global population is expected to increase with 2.2 billion people until 2050. As a result of the population increase more food has to be produced which requires more transport from the countryside to the cities. However, this flow of resources faces some difficulties.

Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp

At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.

Behandling av hypertyreoidism hos katt med radioaktivt jod : en uppföljning av 46 fall

Hyperthyroidism has become the most commonly diagnosed endocrine disorder in cats. The recommended treatment of choice in the literature is administration of radioactive iodine. This treatment has been available at a few veterinary clinics in Sweden since 1999. Forty-six cats treated with a standard dose (80 MBq) of radioactive iodine (131I) at the Swedish University of Agricultural Sciences in the period 2000-2004 were followed for a median of 13 months (range 3-42 months) by means of a retrospective cohort study design. Tables predicting time of survival after treatment were made. At final follow-up thirty-nine cats (85%) were euthyroid, six cats (13%) remained hyperthyroid and one cat (2%) was hypothyroid.

Bekämpningsmedelsrester i dricksvatten : En undersökning av bekämpningsmedel i 50 enskilda brunnar i Laholms kommun

AbstractThe knowledge about pesticide residue in private wells is not well documented in Sweden.Previous studies have detected pesticide residue in private wells, this issue is what made themunicipality of Laholm commission the study. The purpose was to collect water samples from50 private wells in Laholm and have them analyzed for traces of pesticides. The wells in thestudy are spread geographical over the entire municipality. The analysis of the water sampleswas carried out by the accredited laboratory Eurofins. Nine of the 50 wells in this studycontained residue of pesticides and two of these exceeded the allowed concentration of 0,1 ?g/l.Nine different pesticides were detected, among these were BAM, Atrazin and breakdownproducts from Metribuzin.

Skogens produktionsvärden och dess betydelse för Sveriges ekonomi

The forest is characterized by many different values such as those related to forest productivity which are of a big importance for Swedish economy. History has proved that forest resources had helped the country in the transition from the agricultural to the industrial society. Today Swedish forest industry is among the strongest in Europe and significantly contributing to the Swedish export. The industry provides many direct and indirect job opportunities and is one of the biggest employers in the industry sector. It is also worth to notice that the forest can also generate an additional income for the owners, even if the forestry isn?t their primary income source.

Läsning för Folket : En studie av utländskt material i en svensk tidskrift

The society of spreading useful knowledge started to sell its magazine Reading for the People (RFP) in 1834. The idea with the society was to, through the magazine that contained useful knowledge, enlighten the Swedish peasantry. RFP contained articles about agricultural and economy for example.My goal with this essay is to investigate how the use of foreign articles in RFP changed over time. I?m also going to present a field and language categorization of the foreign articles and study the articles from Benjamin Franklin and Charles Dickens and investigate what kind of articles they wrote.

Timmerkvalitet hos björk i blandskog med gran

Birch is the dominant deciduous tree species in Sweden but only 16 % is found in pure birch stands. The majority of the birch (51 %) is to be found in conifer dominated stands. Swedish forest land comprises approximately of 23 % mixed stands and one problem is that for mixed stands there are few management recommendations. The underlying aim of this thesis was to study the management of mixed forest stands of spruce and birch to achieve good timber quality of birch. The study was based on a literature study and measurement in a field experiment launched in 1998 by the Swedish University of Agricultural Sciences (SLU).
