To understand the motives, and perhaps more importantly the barriers, for farmers to convert from conventional to organic farming is of great interest for policy makers as well as for academics. In Sweden and in other EU countries, proposed targets of the area in organic farmland have failed to be reached in spite of different kinds of policy measures. Most studies agree that the average profitability seems to be comparable to or better in organic than in conventional farming. This would indicate that there must be other factors of importance which can explain the low particiapation rate. A higher perceived risk in organic farming with respect to yield and price is frequently brought up as a potential explanation within a qualitative framework.

Idag är konsumentmarknaden inne i en globaliseringsfas som ständigt växer. Marknader har idag öppnat upp sig, och hela världen tar del av den internationella handeln. Det pågår även en tydlig förändring i konsumentbeteendet världen över, då informationsutbytet nu når ut till hela världen. Konsumenter nöjer sig inte bara med den standard som erbjuds på nära håll utan det specifika behovet har gjort att tillverkningen av varor och produkturvalet idag är enormt stort och tidsödande att välja mellan.Företag kommunicerar med olika typer av påverkan exempelvis, direktreklam och varumärkesannonser för att nå ut till sin målgrupp. Samtidigt som urvalet av produkter och tjänster växer sig allt större, tenderar varumärkesutbudet att bli något mindre då allt starkare internationella aktörer etablerar sig på den globala marknaden, och köper upp eller konkurrerar ut nationella aktörer på marknader världen över.

This study investigates the role of yeast in green crop and its impact on the aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary harvest was collected from eight farms and samples from the first regrowth harvest was collected from seven farms. The grass was ensiled in 1.7 l glass silos. After three months of ensiling, silos were opened and silages were stored aerobically for 10 days. Samples from both harvests were ensiled in completely airtight silos, but samples from the second harvest were also ensiled in slightly ventilated silos. Chemical analyses and yeast counts were performed for fresh crop and silage.

The purpose of this study has been to investigate the prospects for identifying and prosecuting individuals suspected of war crimes, within the process of exclusion from refugee status under article 1F(a) of the 1951 Refugee Convention, and using subsequent mechanisms for extradition or prosecution in international criminal law. A number of principles within human rights law and public international law have been advocated by the UNCHR and several human rights NGOs as necessary for a thorough application of the exclusion clauses; one that takes individual responsibility into account and upholds the aims and purposes of the exclusion clauses. There is a discussion as to whether specialised or accelerated exclusion procedures are justified for reasons of security and efficiency, or if they put the rights of the individual at risk and limit the opportunities for gathering information to support investigation and prosecution of the crime in question. Apart from the instruments of asylum law and procedure that have emerged within the EU harmonisation process, there are no general, binding rules on the procedural aspects of the exclusion clauses. One principle that regulates the consequences for the individual of exclusion from refugee status and decisions on extradition is, however, the principle of non-refoulement.

This bachelor-level thesis in historical osteology deals with several aspects of the life-cycle of an RomanIron Age farm in southern Scania. Excavated in the 1980's by Lars Larsson, the farm was located near aplace called Långåker in the Dybäck area, on a cape which stretched out into a minor bog. Our work concerns why the Iron Age people settled the area, how well fragmented bone survives in a bog, what they produced at the farm and how life on the farm finally ended. From the roughly 10 % of the total number of fragments we where able to identify we can conclude, that he species that are present of the farm areusual Iron Age species (dog, sheep/goat, cattle and swine). We also have a relitivly large number of wildanimals in our material (2%).

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.

ABSTRACTThe fauna of the Lower Cambrian is far from fully understood, as is the environment of that epoch. Some of the most crucial moments in the history of evolution takes place during this epoch; the Cambrian explosion and the appearance of ecosystems as we know them. That makes it an important period to investigate. Doing so, the Lower Cambrian offers a lot of problems, one of which is that body fossils are seldom preserved. That has often left us with trace fossils to create an image of the Lower Cambrian life, but also some bedrock features such as ripple marks.The main purpose of this work has been to investigate the possibilities of relating the wave lengths and forms of recent wave-generated ripples to fossil ones, and also to evaluate the methods for that kind of comparison.

The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings. A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce. In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils. The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season. The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.

For many years, sugar beets have been the most profitable crop for farmers with suitable growing prerequisites. During year 2007 when the grain prices increased and the EU reform decreased the payment for sugarbeets, it was no longer obvious to grow sugar beets in the crop sequence. With the latest agricultural reform in mind, farming has turned to a more open market and that is important for the independent farmer to adjust to the prevailing market presumptions. In the theory, scientists distinguish between unique and repetitive decisions. Unique decisions can be described as decisions made ones or not often. The opposite, repetitive decisions are decisons that have been made several times before.

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

Vi har i vår forskning belyst hur elever upplever arbetet med öppna respektive slutna frågor. Vi har framförallt tittat på hur arbetet med öppna och slutna frågor haft för inverkan på elevers möjligheter till perspektivbyte i tid och rum. Öppna frågor har i vår forskning varit lika med hög frihetsgrad medan slutna frågor är lika med låg eller ingen frihetsgrad. Vi har i vår forskning jämfört resultatet av en essäuppgift från två grupper med elever från årskurs 6. Dessa två grupper har innan uppgiften vägletts i temat ?En resa till Kina? i var sin experimentlektion.

Syftet med denna uppsats är att undersöka om rätten att föra talan inför rätta, enligt artikel 16 i FN:s flyktingkonvention, verkställts på ett effektivt sätt i Sydafrika. Rätten att föra talan inför rätta är intressant att analysera eftersom den ofta är förutsättningen för att förverkliga andra mänskliga rättigheter och spelar en central roll för ett fungerande rättssamhälle. Det är vidare intressant att se hur rättigheten implementerats i ett land som Sydafrika. Det var relativt nyligen som landet demokratiserades och befriades från tiden med apartheid. Den nya konstitutionen är i dag starkt präglad av landets historia och sätter ett tydligt fokus på mänskliga rättigheter.

The intensity of cleaning declined dramatically in the early 1990?s in the Swedish forests. Recession, an economic depressed forestry and the new law of silviculture from 1993, where the duty of cleaning was removed have been considered as sources to the decline. This has led to a situation where huge areas of forests are untouched, which can lead to negative effects for those stands in the future. The purpose of this thesis was to find out how the individual landowner acts and feel when it concerns cleaning activities. Has the landowner noticed Södra?s campaigns about cleaning and what sort of measure should Södra implement to increase the members? cleaning activity? The thesis is based on a opinion poll made through a random draw among all Södra?s members.

The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.

Wildlife is a valuable and renewable resource that promotes economical, ecological and social values. These values are important for developing and maintaining many rural societies. However, growing ungulate populations have led to increased browsing pressure on valuable forest trees and crops. Previous studies have proposed supplementary feeding and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the surrounding forest have been lacking.
