Mätning av ekosystemtjänster i jordbrukslandskapet :
Abstract
In order to make the modern agriculture less dependent on non-renewable external inputs, it
has to rely more on ecosystem services. The agricultural system produce not only food, fiber
and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of
nutrients, influencing local microclimate, pollination, biological control and detoxification of
noxious chemicals.
This study is an attempt to get a better understanding about the interaction among different
ecosystem services and different habitats capacity to generate them. An evaluation of eight
different methods is done. The ecosystem services studied are the ability to absorb solar
energy, biomass production, botanical diversity, decomposition and natural predation of
aphids.
Skördemetoder av industrihampa :
Hemp is an old agricultural plant and has been used for hundreds of years for making
textiles, ropes and other fibre products. In the middle of the last century the Swedish
government prohibited all growing of hemp. Natural fibres were replaced by syntetic
fibres instead. Today there is a newly awakened interest for using natural fibres from
renewable materials. Growing of industrial hemp for fiber is allowed in Sweden
again.
I want in my Paper give Swedish growers an insight of which harvesting methods that
have been tried in Sweden and how they worked.
Planering  av  hamnområdet  i  en  sommarstad : en  fallstudie  i  Båstad
Det här är en studie kring ämnet flexibel utformning av offentliga rum, och ett förslag på hur Båstads hamnområde skulle kunna utvecklas till en plats som på ett mer tillfredsställande sätt kan användas året runt. Idag är hamnen en plats som präglas av några månader med intensivt liv och mycket rörelse under sommaren, för att sedan bli en tom och oanvänd plats vintertid. Förslaget har föregåtts av analyser, både under vinter och sommar, av hamnens rumslighet, aktivitet, rörelse och attraktioner, en litteraturstudie kring ämnet flexibel utformning av offentliga rum, samt två studiebesök på mindre orter i Sverige som kämpar med en liknande problematik. Förslaget har också föregåtts av en inventering av området, samtal med tjänstemän på Båstads kommun och näringsidkare i hamnen samt studier av tidigare planprogram och planer för hamnen framtaget av kommunen. Med utgångspunkt i resultaten av analyserna och med inspiration från litteraturstudien och studiebesöken har jag tagit fram ett förslag på hur Båstads hamnområde skulle kunna utvecklas, göras mer flexibelt och därav mer användbart hela året.
Är reducerad jordbearbetning ett alternativ? :
Today cultivation of cereal in Sweden has high costs for establishment in relation to the rest of the world, and if this cultivation will be able to continue, the farmers have to control their costs. It is important to see all costs, not the maximum harvest achieved, but the net result. All farmers have different conditions with respect to soil, direction of the farm and were the farm is located geographically. With the right knowledge and ambitions, we think most farmers could change to reduced tillage.
In this paper we have tried to find out if reduced tillage is an alternative for farmers.
Miljöanpsassad metod för hjultvätt
In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.
Norra Botkyrkas undre värld : En inblick i antihjältarnas vardag
The purpose with this study was to describe and analyse the daily activities of a criminal group in a southern suburb of Stockholm, Norra Botkyrka, and their attitude to drugs, the police, crimes in general, accomplices and their plans for the future. The study is a combination of different qualitative methods that is built on unobtrusive methods and interviews that was carried out during winter in 2006 and spring in 2007 and six interviews. My interest to carry out this study was grounded on my several years of experience as a prison and probation officer in the prison. I chose to ?live? with a group of criminals and participated in some of their social activities.The respondents that I chose to call ?anti-heroes? proudly tell me about their criminal lifestyle that characterizes of violence, drugs, crimes and conflict where this people show no regret.
Diseases and causes of death among camelids in Sweden : a retrospective study of necropsy cases 2001-2013
Camelids, especially alpacas, have increased in popularity during the last decade, with the result that they are more frequently encountered by field practicing veterinarians and pathologists. Knowledge regarding their health care and their diseases under Swedish conditions is, however, limited. This became clear in a postal survey among Swedish alpaca owners conducted in 2008. To improve knowledge about camelids in Sweden, this study has examined 107 necropsies, including 93 alpacas and 14 camels, conducted at the National Veterinary Institute (SVA) in Uppsala and at Eurofins in Kristianstad and Skara during the period 2001-2013. The study has shown that camelids in Sweden suffer from diseases similar to those previously reported in other countries in Europe and North America.
Behandlingsvåtmarkers reningseffekt på aktiva läkemedelssubstanser under vinterförhållanden : En studie av fyra svenska våtmarker för avloppsrening
Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.
"Så nära men ändå så långt borta" : ? en studie om hållbar destinationsutveckling på Sandhamn
Sustainable destination development has in recent years become an increasingly important concept for tourism destinations. A destination must take into account the environment if it wants to continue being a successful tourism destination in the future. This essay investigates what needs to be developed on theislandofSandhamnfor that the destination can be more attractive in the off season and how the players on Sandhamn integrate to develop Sandhamn in a sustainable manner. One market research and interviews with five different players were made. Through these interviews grew an understanding for how the cooperation between the municipal and the private party looks like and how the history of Sandhamn is the foundation for the islands tourism development.
Vattensork och åkersork - skadegörare i svensk fruktodling
There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.
Subjektiv och objektiv bedömning av underlag på svenska hopptävlingar på elit- och nationell nivå
Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.
Utvärdering av ett silotorksystem för spannmål utrustat med omrörare :
The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.
Förekomst av törskate (Cronartium flaccidum, Peridermium pini) på tall (Pinus sylvestris) i relation till markfuktighet och fältskikt : en studie om 2000-talets törskateepidemi i norra Sverige
Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.
Övergödning av Mälaren : Betydelsen av antalet beviljade dispenser av stallgödselspridning vid Sagån
Eutrophication was recognized in the early 1900's and results in severe algal blooms, increased biomass production and eventually leads to an altered ecosystem. In Mälardalen we find the most eutrophic lakes. Most of the applied phosphorus and nitrogen into seas and oceans comes from agriculture, and the nutrients losses are affected by local weather conditions and soil type. Guidelines for storage and distribution of manure were introduced in the 80s, and the rules were strengthened January 1, 2010. Localities and previous county administrations can whether there are special reasons, grant an exemption for manure application during winter-periods despite the current ban.In this essay I have examined how many exemptions of manure application that has been granted at the Sagån river, and what implications it has for the eutrophication of Lake Mälaren.
