In this essay a model of a potential illegal hunter?s decision-making is created and presented in order to provide an overview of important parts of the complexities associated with the current Swedish predator policy. A comparison is made between a livestock owner?s economic incentives, and the expected costs faced by the potentially caught lawbreaker. In accordance with economic theory the benefits and costs of illegal hunting are compared and thus the optimal choice is determined where marginal costs and benefits are equal.

Along with other European farmland birds, the skylark (Alauda arvensis) has declined rapidly since the 1970?s. Between 1975 and 2003, the Swedish population of skylarks declined with 64 %. In Britain, the decline is often explained by alterations in Farming practices in general and the shift from spring-sown to winter-sown cereals in particular. The dense vegetation structure of winter cereals is limiting the number of breeding attempts possible, causing the entire population to decline.

Burkina Faso as well as most sub-Saharan African countries struggle with providing food for a fast growing population. The dominating Farming system is agroforestry parklands. Agroforestry parklands can broadly be defined as areas where scattered trees occur on farmlands as a result of selective clearing. The presence of trees in crop fields may in the long term have a positive effect on the production of annual crops. It is commonly discussed, but not proven, that the presence of trees leads to increased groundwater recharge due to higher infiltration capacity of the soil.

Lerbodaälven is a river in the municipality of Kil which, due to high phosphorus content is not meeting the requirements for good ecological status according to the Water Framework Directive. The purpose of this report is to investigate the causes for the high content of phosphorus that has been measured in Lerbodaälven between 1995-2010. Four questions will be answered in this report. 1. Does the sewage treatment work affect the phosphorus level in Lerbodaälven? The result from the time series analysis shows that the sewage treatment works have a small impact on the phosphorus level in Lerbodaälven.

Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.

SummaryIn the area to the east of Hue city, in Vietnam, lays Tam Giang lagoon, one of Asia's largest lagoons, with an area of 22,000 hectares. This lagoon is suitable for aquaculture. One reason for this is because the salinity differs from sweet to salty in different parts of the lagoon. The Vietnamese Government advocates an increase in environmentally-friendly aquaculture and the fish Siganus guttatus (Rabbit fish) is a candidate for this. This fish eats mainly algae and can be cultivated in a polyculture.

Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic Farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers. This project contributes to this knowledge by investigating whether relatively simple and repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.

Allanblackia is a genus of trees that grows in the rainforests of West, Central and Eastern Africa. Its big fruits contain seeds very rich in oil which has been used by local communities for cooking and making soaps. The native stands are threatened by overexploitation and the demand for the oil is much greater than the supply. Domestication programs, aiming at introducing the trees to small holder agroforestry systems, have been started for some of the species. The main aim of this study was to investigate the soil requirements of Allanblackia stuhlmannii in terms of chemical and physical parameters, as revealed by the soil conditions in native stands. Another aim was to see if these varied along an altitudinal transect.

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in Farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.

Bergsbruket har under lång tid haft stor betydelse för Sverige både ekonomiskt och politiskt. Det har också haft en inverkan på naturmiljön bland annat genom huggningar för bränsle och utsläpp av tungmetaller. Ett av de områden i Sverige som är mest känt för sin metallhantering är Bergslagen. Idag är många gruvor nedlagda. En som fortfarande är i drift är gruvan i Garpenberg i Dalarna.

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.

The open air museum of Disagården is situated in the Old Uppsala parish, Uppsala municipality, are projected to portray a double row village, before the land enclosure, on the Uppsala plain during the 1860s and 1870s. Disagården operates under the County Museum of Uppland and serves as an exhibit of Uppland's Farming culture during the late 19th century. However, an open-air museum is a complex institution where many interests are linked together. Disagården aims to simultaneously portray an historical environment while offering broad public appeal. The Disagården open air museum was inaugurated in 1931 and consists of relocated buildings that together form three farm complexes "Gränbygården", "Skuttungegården" and "Bärbygården". The thesis explores how the close surroundings of a typical farm in Uppland looked during the 1860s and 1870s. This historical depiction has then been applied to Disagården in a development suggestion creating a foundation from which Disagården can structure the close cultivation of the different farms. The basis of the development program has primarily been compiled through archival and literary studies but also through on-site visits and interviews. How did the concept of open air museums start and what were the ideas behind the concept? Which external influences affected the situating of cultivations and buildings? Which crops and species were present on the farms in Uppland during the specified time period? What was the relation of the different structures to each other? Which organizations had influences on the farmer's household of the Uppland plain? The thesis attempts to clarify the answers to these questions. The influences affecting on the farmer's household in Uppland were probably numerous.

Frölunda-Aspvik Säteri, a company just outside Stockholm within the agriculture and forestry sector, has developed a business idea around countryside tourism as a complement to their existing business. The idea is to offer a high quality and functional way of living in small cottages surrounded by beautiful nature and landscape of cultural importance. There will also be a range of additional activities available such as hunting, canoeing, cycling etc. The project should be done with minimum impact on the surrounding environment and the importance of the ecological system should be at the forefront of all business decisions. At present the company wants to have a better understanding of what the future trends are within tourism, how its business idea fits in with future trends within tourism and how to stay competitive.The purpose of this research paper is to identify the social driving forces that have an impact on people?s lifestyle and choice of holiday destination in the future, and present how these factors affect the travel industry.
