Produktion av krukodlade örtkryddor i växthus och dess utsläpp av växthusgaser i Sverige : energianvändning och beräkning av koldioxidekvivalenter
Abstract
The global average temperature has increased by 0,74°C over the last 100 years. Most probably, the explanation is due to increasing use of fossil fuels and the agricultural expansion of land use. The new life stile of mankind leads to increasing concentrations of greenhouse gases in the atmosphere. Food consumption contributes with approximately a quarter of the total greenhouse gas emission per person and year, why it is an important task to reduce these.
The aim of this work is to quantify energy use and greenhouse gas emissions for (Swedish) herbs produced in Swedish greenhouses. The study is based on a LCA (Life Cycle Assessment) and collected data from participating companies producing herbs in pots.
Ley management : a means to improve forage quality and production
Higher demands of competitiveness and efficiency have led to increasing sizes of farms, with more land, more capital and more comprehensive logistics. The aim is to gain benefits of scale economies that reduce the production cost per unit. However, a greater extent of the business exposes the farm of increased risk where small deviations rapidly can erase the benefits. A modern dairy farm thus put high demands on the farmer?s ability to coordinate, plan and manage the forage production through the whole process until storage to obtain silage of the desired quality and quantity at the right price.
The objective of this study was to design a simple model, i.e.
SharePoint teknologi? en utvärdering av tekniken och dess möjligheter
Microsoft har utvecklat ett verktyg för informationsdelning och samarbete, detta mjukvarupaket är känt under namnet SharePoint teknologin. Vi har i detta examensarbete extraherat delarna av SharePoint teknologin. Vi fann, att paketet innefattar två huvudsakliga mjukvaruapplikationer som namnges SharePoint Services och SharePoint Portal Server 2003; vidare fann vi att SharePoint Service kan användas på egen hand, och att SharePoint Portal Server 2003 bara är en extension. I vår uppsats undersökte vi miljön som krävs för att åstadkomma en framgångsrik installation. Vi beskriver de olika systemarkitekturerna som paketet kan arbeta på och vilka andra mjukvaror som är nödvändiga för att använda SharePoint teknologin fullt ut.
Priset på åkermark : påverkande faktorer
The price of farmland has risen sharply in the last 20 years. This has led to discussions about what creates the value of farmland. The aim in this study was to try and find what factors are affecting the price on farmland. The area that is studied is the counties around Mälardalen during the period 2005 to 2009.The method chosen to achieve the objective is the hedonic price model. The variables are chosen after a preliminary study where a literature search has been made and a number of interviews with people in the industry.
Liquid diesel biofuel production in Sweden : a study of producers using forestry- or agricultural sector feedstock
The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of petroleum diesel.
Vindfällning, tillväxt och plantuppslag i en 13-årig granskärm i Medelpad :
The interest for alternative forest regeneration methods increased significantly during the 1990´s after 50 years dominance of the clear-cutting system (Holgén & Hånell 2000). One reason for this was that clear-cutting was being more and more questioned by different envi-ronmental organizations and because the forest sector for economical reasons wanted to find cheaper ways to regenerate forests. In the beginning of the 1990´s two shelterwood experi-ments were established in a joint effort by Svenska Cellulosa Aktiebolaget (SCA) and the Dept of Silviculture, Swedish University of Agricultural Sciences (SLU). The experiments include various forms of cutting and shelterwood densities and represent productive spruce forests in central and north Sweden (Roggsjön in the province of Medelpad and Skikkis-jöberg in the province of Västerbotten, respectively ). The experiment next to Roggsjön has been reported earlier in three MSc theses, and is also the focus of this thesis.
Levande vikt vid olika åldrar och sambandet med bröstomfång och mankhöjd hos SRB och SLB :
Live-weight at different ages for Swedish Holsteins (SLB) and for the Swedish Red and White Breed (SRB), and the correlation to heart girth and height at withers.
The aim of this investigation was to study the live-weight changes and mature weight for the Swedish Red and White Breed (SRB) and for Swedish Holsteins (SLB), and to estimate the correlations between body weight and body measurements such as heart girth and height at withers, respectively. The material used was from one of the experimental dairy herds (Jälla) of the Swedish University of Agricultural Science. It included recordings on 293 dairy cows with information from 7142 weight occasions and recordings on 275 dairy cows with information of 557 heart girth measurements and 560 measurements of height at withers. The registrations were done during 1993-2002.
There was a large variation in live weight between cows in different ages and lactation stages.
Svensk tjänstehundsavel : en återblick och nutidsbeskrivning samt förslag inför framtiden
In 1936 a governmental breeding project was started with aim on military use. The police later came to use dogs from this project as well. In order to utilize dogs that could fit for other purposes training and education of dogs for search of different substances and of guide dogs for blind persons was performed. A political decision to privatize the whole dog programme was taken in 1992.
During most part of the time one had serious economical issues since too few of the dogs that were bred could be considered to fulfil the basic demands for service. To satisfy the need of service dogs private bred dogs were bought as well.
Informationsbehov vid ett unikt beslut : en studie av sockerbetsodlare i södra Skåne
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.
Näringsretention i återskapad våtmark på betesmark : studier av en mad vid Bornsjön
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).
Effects of biogas residues on respiration and denitrification in arable soil : evaluation of methods, microbial activity and agronomic implications
Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.
Skydd mot nitrat och bekämpningsmedel i dricksvatten : åtgärder och styrmedel i fem länder
In many European countries there is an increasing concern about the occasionally
high concentrations of nitrate and pesticides in drinking water. The advent of the EU
Water Framework Directive particularly highlights this. The directive states that all
large drinking water sources should be identified and protected from pollution before
2009 and that by 2015 all water bodies should reach a 'good status'.
In Sweden about 60 percent of the drinking water sources have protection areas. This
means that about 700 new water protection areas need to be designated before 2009.
This will affect many farmers, restricting their farming practices.
The purpose of this study was to investigate which methods are used in other
countries concerning nitrate and pesticide pollution from agriculture. From this, the
expectation was to generate ideas on what could be undertaken in Sweden when
designating new protection areas.
Gotland ponies on extensive pastures ? a welfare assessment
Swedish farmers have the possibility to be subsidized by EU rural development programme for grazing animals on pastures to promote the biodiversity of flora and fauna. The environmental remedy sometimes does not allow supplementary feed and at the same time the Swedish Animal Welfare Act and the Swedish Agricultural Board?s regulations for animal welfare and protection states that animals, in this case horses, shall be fed with food of good quality and adapted for the species. The regulations also state that they should have an individual feeding regime that enables them to maintain a normal body condition.
The aim with this master thesis has been to investigate if it is possible to keep Gotland ponies on extensive pastures, during late spring and summer and still maintain animal welfare. The horses were assessed every fourth week using a welfare assessment protocol developed in line with the Welfare Quality® project (submitted, Viksten et al) where physical, behavioural and resourcebased parameters were observed.
Twelve one-year old stallions of the breed Gotland ponies purchased from different breeders were used in the study.
GIS och statistik vid dräneringsområdesvis kväveläckagebeskrivning i Halland
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.
The Countryside dream : amenity Migration and the new transit-oriented communities
This is a final thesis in landscape planning, at the Swedish University of Agricultural Sciences (SLU). The study examines the current phenomenon of amenity migration and the international discourse applicability of the a "Countryside dream" in a small neighborhood in Käglinge, part of the transit-oriented community Oxie just outside of Malmö in the southern part of Sweden.
The critical starting point of the study is the how many planners idealize the dense city with its positive proximity qualities. However, since the late 1900s, many people have instead started to idealize living in more rural or naturally appealing landscapes, often just outside a bigger city, with good transit possibilities (both by car and bus as well as by train).
The phenomenon of amenity migration ? the migration to a new, more appealing everyday environment considered to have more amenities, is very relevant today since many smaller communities are becoming more transit-oriented, allowing the inmigrants to work in some bigger, dense town while living in a small-scale, less dense semi-rural community.
More dense transit-oriented communities are however also an ideal to planners in Sweden, but to what extent can Käglinge in Oxie ? a neither rural nor urban community - fulfill a possible countryside dream, and what role does the train station have in the in-migrants everyday life?
The study has a theoretical starting point in literature regarding amenity migration, countryside ideals, representations of the countryside and the possible migrants themselves, giving a broad perspective on these related issues. The case study of Käglinge in Oxie is then presented, including interviews with Käglinges in-migrants.
