Motiv och värdering vid köp av skogs- och lantbruksfastigheter i Kronoberg och Blekinge

The purpose of this study is to find out how buyers of forest-and farm land have valued the property's various parts. How buyers has valued the forest, field, pasture, house and the farm buildings on their property. A questionnaire with 22 questions was sent to 68 people how had bought a property in Kronoberg or Blekinge. They had bought the property in 2010 and first half of 2011, and the properties have been provided by LRF-konsult. To each question there were several alternatives and the buyers would choose the alternative that was most similar to his or her opinion. The study is based on 57 responses.

Strategier vid generationsskifte : ekonomiska implikationer för olika intressenter

A large number of farms within the agricultural sector will shortly be facing a point of time where the farm will be transferred to the next generation. The grantor can choose between totally 8 different strategies to transfer the farm, of which purchase, gift and a mixed form of these are the most common. During 2007 almost 10 000 transfers of agricultural estates occurred in Sweden and the expectation for the coming years is that about 15 000 estates will be transferred each year. By the time a transfer is about to materialize there are usually several stakeholders that in one way or another is trying to influence the outcome of the transfer. The choice of transfer method affects the conditions and possibilities for compensating the siblings.

Migration losses of Atlantic salmon (Salmo salar L.) smolts at a hydropower station area in River Åbyälven, Northern Sweden : passage fates at a reservoir, a power house and a bypass structure

A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.

Solenergi : en lönsam investering för ett lantbruk?

A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.

En läroplan utan stort tolkningsutrymme? : En undersökning av Lgr11 ur ett läsarorienterat perspektiv

This essays aim is to investigate the possibilities of subjective interpretation of Lgr11, the Swedish curriculum for elementary school. The assignment that the Swedish authority Skolverket got in 2009, was to create a curriculum that would grant that the students achievements would not be influenced by any subjective opinions and that all elementary schools in Sweden will give an equivalent education. In the Government bill this is a theme throughout the text and the Minister of Education has also claimed that this document will leave very limited space for subjective reading and interpretation. He says that Lgr11, in contrast to the previous curriculim Lpo94, will clarify what the purpose of the different subjects is and on what grounds the assessment of the students should be based.The method used is the literary theories of reader ? response as they are expressed by Literarycriticist Stanley Fish.

Community Supported Agriculture (CSA) - en väg mot ökad uthållighet? : en studie av Ramsjö gård

Over the past one hundred years, there has been an increasing globalization and industrialization of the food systems. As a result, the distance between the production and the consumption of food has increased, both in time and space and in the minds of people. There is also an increasing concern for the environmental effects of industrial farming and the long distance transportation of food. Sustainable agriculture and efforts to build more sustainable food systems has emerged in opposition to the global food market. The definitions of sustainability usually include environmental, social and economical aspects. To build more localized food systems is seen as one way towards increased sustainability.

Försäljning av närvärme :

To provide our company a new business opportunity I have in this essay examined the economical possibilities to sell energy. I have chosen to do a case study on my own farm in this essay. The farm is focused to cropping and also have some properties for hire. The farm is situated in the village of Fjelie and that?s where the opportunity for selling heat are. Fjelie has about forty houses. The idea is to build a plant where straw is being used as fuel.

Tidsstudier i kalvuppfödning :

Swedish agriculture stands in front of big changes the whole time. As a milking producer you have to adapt and develop the company to these changes and find the best solution. This potential is easy to find if you compare your company with other similar companies. Labour cost is the biggest cost in milking production after the cost for food. Today it is rather easy to measure how many hours per cow different system of cow houses needs, but we do not know so much about how many hours it takes to breed a calf. To learn more about the labour time with the calves during the first time after the calf was born, I made time studies on five different farms with calf hutches, automatic milk system, large calf boxes, and smaller calf boxes with teat buckets.

RME - produktion på gårdsnivå

With a shifting world market and periodically profitability issues, Swedish farmers seekalternative ways to enhance their profitability. One interesting alternative to get a highervalue and enhance products is biodiesel, a way to improve the profitability on a farmscale.The diesel that is produced and sold, already have a mixture of 5% biodiesel, andthere is a possibility to add more biodiesel to it. By developing new engines severalengine-manufacturers now allow a mixture up to 100% biodiesel in their engines. Hencethere is a market for an increased production of biodiesel. The aim of this study were toinvestigate the possibilities and the problems related to farm-scale production ofbiodiesel, and to study the profit margin in the production.

Kväveförluster och energianvändning på mjölkgårdar i västra Sverige :

Protecting the environment has with time grown to take a more central role in the society. Agriculture plays an important role in the society since this sector produces our food. More thorough research on how agriculture affects the environment is therefore motivated. This research can be used to improve the agricultural practice from an environmental point of view. This is something that both the farmers and the consumers can profit from. This study aims to form the basis for creating environmental indicators for use of nitrogen and energy on dairy farms. Twenty-three farmers in western Sweden have been interviewed about their farms, both organic and conventional. They produce milk with different intensity, defined as the amount of milk delivered (sold) per hectare of arable land.

Barriers to convert to organic farming and the role of risk : an empirical application on Swedish data

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.

Vindkraftetablering och uranborrning i Dalfors-Dalarna; Acceptans bland närboende

The dependency of fossil fuels has to decrease in order to reduce emissions of green house gases. Wind turbines generate electricity with low environmental impact, but the local opinion in Sweden is sometimes an obstacle to new developments. The acceptance of nuclear power increases at the same time. Mining uranium is once again on the agenda and prospectors are currently drilling for uranium. This cross-sectional study deals with acceptance of wind farms and uranium drilling.

Hjärtfrekvensens förändring vid sinläggning av undervisningskor vid institutionen för kliniska vetenskaper :

It?s been noted that cows held at the section of ruminant medicine and epidemiology, Swedish University of Agricultural Sciences (IME), used for the education of veterinary students, have a lower heart rate than what is considered normal for ruminants. In this investigation the heart rates of seven lactating cows were recorded continuously during the period around drying off. The first recording took place at the farm from where the cows were bought, and then their heart rate was monitored after their arrival at IME and further on until they were completely dried off. The results were then compared to the heart rate of seven already dried off cows from the same farm.

Genomgång av kemikalieförteckning som exempel på uppströmsarbete : en identifiering av utfasningsämnen i spillvattnet

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.
