Naturvårdsrestriktioners effekter på brukandet av ädellövskogen i Skåne :
Restrictions in nature conservations are increasing the influence of forest management. Nobel broadleaved forests are more influenced than other forests, because they are considered to be more valuable than other forest types in Skåne. There has been a lack of knowledge about the amount that is set-aside for nature conservation and what types of forest that is concerned.
These are the main questions to be answered in this thesis. Moreover has the timber quality been compared between set-aside and non-set-aside areas since it affect the financial conditions for the forestry in nobel broadleved forests. The last asked question deals with the financial consequences of set-aside.
Hybridlandskap : nya möjligheter för offentliga platser i staden
This project explores how artificial landscapes as parks and squares above ground can save space by using the vertical voids in urban environments and how they can create spatial and social as well as ecological qualities and connections.
Hybrid landscapes are a phenomenon of current interest within the field of architecture and urbanism. Architecture as surface, where facades and roofs become possible to tread, is a relatively recent occurence that has over the past few years become an increasingly common sight in architectural magazines and on international architecture exhibitions. Many of my selected reference projects have often been associated with sensational contemporary design trends generated by advanced computer software. But the phenomenon is also a result of other different currents of change that exist within today?s society, such as densified cities with a lack of open space, which is also expressed in architecture.
Svensk prickskytt i urban miljö : Förändring, utveckling och behov
Dagens konflikter utspelar sig mestadels i helt eller delvis bebyggd miljö och vikten av en uppdaterad och väl fungerande prickskytteförmåga är därför central. Detta till trots, återfinns stora brister i den svenska prickskytteutbildningen vad avser just den urbana miljön. Denna uppsats syftar till att dels bidra med nya infallsvinklar samt ge ett användbart arbetsunderlag för Försvarsmaktens vidare utveckling i ämnet. Genom att komma på det klara med hur prickskyttar utbildas och används i Sverige idag och jämföra detta med utländska modeller och andra länders goda och sämre erfarenheter, vill jag ge förslag på hur den svenska prickskytteutbildningen skulle kunna utvecklas. För att ge uppdaterad information har jag begränsat min efterforskning genom att mina studier av andra länders prickskytteerfarenheter avser det senaste decenniets förehavanden, snarare än utvalda länders specifika tillvägagångssätt.
Ensiling wet brewer's waste in peri-urban areas of Kampala, Uganda
Ett av de vanligaste fodermedlen hos jordbrukare i Kampala är drav, en biprodukt vid ölframställning. Hög efterfrågan, dyr transport samt dålig lagringskapacitet leder till att tillgången på drav begränsas. Ett sätt att lagra drav och således förbättra tillgängligheten är genom ensilering. Denna studie genomfördes som en Minor Field Study, och var en del i ett projekt mellan SLU och Makerere University, ?feed for livestock in urban/peri-urban areas of Kampala?.
Persontäthet vid utrymningsberäkningar : Köpcentrums persontätheter
The aim of this study is to evaluate whether the value of occupant load is over or under estimated when the Swedish general value for department stores, 0,5 person/m2, is used for dimensioning shopping centers. The data that was analyzed derives from seven shopping centers and one department store. A conservative method was used to calculate the occupant load factor. The analysis shows that two groups can be discerned: one group that is characterized by a lower occupant load factor that does not exceed 0,3 person/m2, and one group with a higher occupant load factor. Shopping centers with a higher occupant load factor are located centrally in large urban areas.
Skötselåtgärder vid nyetablering av skyddszoner vid bäckar i södra Värmland :
Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.
Effekterna av urbanisering, barksprickedjup och solexponering på lavfloran i sydöstra Sverige
Studies have shown that air pollution, as well as bark fissure depth and sun exposure of a tree can have an effect on lichen growth as well as abundance of lichen species. The aim of this study was to find out the relative importance of these factors. 211 oaks in south eastern Sweden were surveyed for presence of 17 lichen species, as well as the total number of lichen species. Half of the trees were situated in urban areas and half in the countryside. For each tree the bark fissure depth was measured and the sun exposure of the trunk was estimated.
En ficka full av frihet; hur användningen av pocket parks kan verka restorativt på människor i urbana miljöer
Ett livslångt intresse för psykologi och landskapsarkitektur ledde in på spåret att
diskutera vad två av dagens stora frågor inom ämnet kunde erbjuda om de slogs
samman; positiv psykologi (?Positive Psychology?) och hållbar stadsutveckling. Alla
människor utsätts emellanåt för stress, vilken vi är konstruerade att kunna hantera.
Trots det är en av de största orsakerna till sjukskrivning i vår tid just stress- och
relaterade sjukdomar. En välkänd källa till restoration eller återhämtning är grönska
och natur. Så frågan i denna uppsats rör huruvida små grönområden i den täta
staden kan verka restorativt på människorna som besöker dem.
Social hållbarhet och förtätning : en kritisk studie i förtätningens sociala paradoxer
Densification is one of the urban visions for sustainable development - a vision that has become a part of the solution to the unsustainable sake dilemma. With the dense city land will be saved, energy consumption reduced and social cohesion improved. The dense city is considered to be ecologically, economically and socially sustainable. Applying an urban design concept has thus proven to be problematic. Density has been found to be a complex concept
which is far more complicated than measuring how much built surface that needs to be covered.
It is also not disputed what different degrees of densification mean and whether densification in itself is sustainable.
H?RNERVMOSSA I SANDSJ?BACKA NATURRESERVAT: Analys av h?rnervmossans invasivitet p? ljunghedens vegetationstyper
Heath star moss (Campylopus introflexus) is an alien species in Sweden and is currently classified as composing a "very high risk? of becoming invasive in the country according to SLU, and has in several parts of the world taken over large areas in a short time. The moss is characterized by its preference for disturbed and burned land, something that occurs on the heathland in the Sandsj?backa nature reserve, when burning for nature conservation purposes is carried out annually. Sandsj?backa's heathland is a valuable ecosystem and is one of the few heathlands in a favorable condition that remains in Sweden after strong reforms in modern agriculture in the last century, which led to forest succession of these cultural environments.
Klimatförändringars påverkan på kulturmiljöer i Uppsala stad ur ett geovetenskapligt perspektiv
Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes.The water flow in Uppsala is estimated to increase during winter and decrease during spring and summer. Precipitation will gradually increase as well as the intense short period precipitation. The average temperature is estimated to increase as well.
Holmbergska tomten i Lund : en fallstudie utifrån begreppet ?Urban Wilderness?
I mitt examensarbete till landskapsarkitekt har jag valt att göra en fallstudie utifrån begreppet Urban Wilderness. Som studieobjekt har jag valt en plats i Lund som kallas Holmbergska tomten.
Holmbergska tomten är en ca 1,5 hektar stor ödetomt. Platsen har en historia som sommarnöje och trädgårdsmästeri. Sedan början av 70-talet, då staden köpte tomten, har vegetationen på platsen fått utvecklats fritt utan skötselåtgärder - förutom att man tagit ned sjuka och döda almar det senaste årtiondet. Det har lett till att platsen fått en vild karaktär, med gamla stora träd, sly,
snåriga buskar och ett mycket vackert fältskikt med överdådig vårblomning.
Värdet av stadsodlingen i Rosengård : utifrån fastighetsägares perspektiv
MKB fastighets AB förvaltar stora delar av Malmö stads utrymmen vilket ger dem stort inflytande och möjlighet att utveckla stadsmiljön. Det finns intresse bland aktörer, bland annat Odla i stan, att visa på fördelar med stadsodling/ boendenära odling. Forskning kring stadsodlingens värde behövs för att motivera
stadsodlingsprojekt och anställningar nu och i framtiden. Denna studie utreder vilka värden som skapas av stadsodlingen i stadsdelen Rosengård i Malmö och hur det
kan gynna de fastighetsägare som verkar i området. Begreppet stadsodling började användas i Sverige runt 2009 men det finns en tradition att odla i staden för egen
konsumtion.
Solenergi på Nordvästra Kungsholmen
The energy that the earth receives from the sun hourly has potential to cover a year?s energy demand in the world. Further, this type of energy is environmentally friendly, natural and free of cost. This report covers solar energy in an urban environment and consists of a case study of installations of photovoltaic cells in a part of the city of Stockholm. It is mainly the economic aspects that are covered but there is also a discussion about the practical consequences and the sustainability as a result of integration of solar energy in an urban environment. The aim of the study is to present results from economic calculations for utilization of solar energy in chosen buildings in Kungsholmen in Stockholm.
Bruka utan att förbruka - när andra intressen än ekonomin får styra
To have a forest area close to the city is of great importance for the city population?s well being. Children develop their motor skills, concentration and imagina-tion and the adults have a place to shake of the stress from work. Forest areas are used to exercise at, play in and to find a moment of peace and silence.
The urban forest and the old farming pastures at Markussonvallen and Per-Isakssonvallen already has natural assets worth to preserve and a great potential to create more. The goal is to develop a forest with a variation of tree species and ground vegetation that will appeal to the human senses and different animal species such as birds, insects etc.
