Challenges and incentives for sustainable manure management in Russia

The Baltic Sea is threatened by eutrophication that largely is due to nutrient leaching from farmland within the catchment area. To solve this problem the surrounding countries cooperate within various configurations such as HELCOM and the EU-financed project Baltic Compass. Poor manure management in Russia has been discussed frequently the last couple of years. A literature review of different types of reports and legal acts is the core of this degree project which has been performed in connection to two ongoing research projects financed by EU (Baltic Compass) and SIDA. It is supplemented with interviews with Swedish agricultural consultants and travel reports from two occasions when I had the opportunity to discuss with Russians active within the agricultural sector. Different hypotheses were investigated and discussed. The environmental debate in Russia is quiet and there is a widespread approach that economic profit always trumps environmental concern ? a Soviet heritage that influence the Russian agriculture considerably. The Russian legal acts on stable manure management focus mainly on sanitary questions and only secondary on nutrient leaching.

Analys av designalternativ för snabbare dynamik i kolkraftverk med koldioxidavskiljning

Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce the emissions of carbon dioxide from combustionin a coal fired power plant is through carbon capture and storage (CCS).Post-combustion capture is a technology to separate carbon dioxide from the uegas after the combustion for efficient transport and storage. The steady state operationof coal fired power plants with post combustion capture has already beenthoroughly investigated on a pilot scale, however much work remains to investigatethe plants dynamic operation.

Risk och osäkerhet i vindkraftsinvesteringar : Hur företagens investeringsbedömning påverkas av deras syn på risk och osäkerhetsfaktorer

Nyckeln till ett framgångsrikt och värdefullt företag är att göra bra investeringar eftersom det är investeringarna som skapar den avkastning som dess ägare får som ersättning (Froot, et al., 1994). Om företaget strävar efter att göra värdemaximerande investeringar måste de därför bedöma vilka investeringar som kan tänkas generera en avkastning som är större än kostnaden för kapitalet som investeras (Brealey, et al., 2014). Detta är den teoretiska grundregeln för all investeringsbedömning (Brealey, et al., 2014). Men eftersom framtiden är fylld av risk och osäkerhet är bedömningen av en investerings ekonomiska värde ingen enkel sak (Sandahl & Sjögren, 2005).I företagens strävan att tämja denna risk och osäkerhet har Mikes (2009;2011) identifierat två olika kulturer, den beräknande kulturen och den visualiserande kulturen. Dessa kulturer präglas av sin syn på vad som är meningsfullt att sannolikhets bedöma och vad som inte är meningsfullt att sannolikhets bedöma (Mikes, 2011).

Skogsbrukets erfarenheter av Poppel Populus sp. i Skåne :

In Europe poplar plantations has been planted for more than one hundred years. In the first plantation was made in 1940. The interest for poplars has since then shifted over the years and has for long periods been very low but is now slowly increasing again. The main reasons why poplars are becoming more interesting are because of their great production potential. Nevertheless, the knowledge of how to mange poplars in Sweden are very low and very little research has been done concerning management of the species. The objective for this study was to; 1) investigate and document experience and results obtained in practical Swedish forestry, 2) to give a fair picture of the perceived advantages and disadvantages that the poplars has for the forestry, 3) document what the foresters that has experience and those who has no experience of poplar plantations thinks about the potential of poplars.

Livet mellan husen : ett utvecklingsförslag för Disagården

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.

Hur motiverar man beställare till att ge utrymme för landskapsarkitekten att arbeta med brukare i en planerings- och projekteringsprocess?

Residential estates are created without any adaptation to the users who will use them. Clients wouldprofit on involving users in an early project stage to create housing estates adapted to the user?s needsand wishes. Clients of the housing estates that require missions from consultants should realize that noone exclusive can represent other people's needs, regardless of the theoretical expertise they possess. TheSwedish million programme in the 1970s is an example of how objective expertise gained control, whichled to the creation of outdoor environments where few wanted to stay and live.

Klimat i miljökonsekvensbeskrivningar : hantering av klimatförändringar och extrema väderhändelser i MKB

There has always been global warming on earth and it is because of it that the earth is inhabitable. Without global warming the temperature on earth would be around -18 ° C instead of today's + 15 ° C. Global warming is generated by greenhouse gases like carbon dioxide and methane which trap long wave radiation in the earth's atmosphere. The problem today is that the global concentration of green house gases has significantly increased since the 1750's as a result of human activity. Today's values widely exceed the preindustrial values.

Klyftan mellan byggare och arkitekt : markentreprenören och landskapsarkitekten

In my work I have received a lot of concrete advice about improving the cooperation between landscape architects and contractors. Here is a list of suggestions from both cathegories: Landscape architect's advice: ? Be humble, show respect. ? A practical approach makes cooperation easier. ? Call together a startup meeting with all the consultants and builders. ? Establish a network of contacts with serious contractors whom you can recommend to customers. ? Don't hesitate to ask the contractor for advice; they often have lots of useful knowledge. ? It is important to have clearly written and thoroughly worked out documentation. ? Never let a newly graduated landscape architect visit the buiding site without the company of an experienced colleague.

Miljösystemanalys av VA-system i omvandlingsområden : fallstudie i Värmdö kommun

Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants. When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

Shelter use of horses during Swedish summer in relation to weather conditions and insect abundance

Outdoor housing of horses? best fulfils the horses? need for physical activity and it is an alternative to the more cost and energy demanding indoor housing in stables. Furthermore, if outdoor housed horses have access to shelter they can generally cope well with adverse weather conditions such as high or low ambient temperature, heavy rain or strong winds. In this study, the daytime shelter-seeking behaviour of three groups of horses housed outdoors was studied during the summer. The aim was to evaluate whether shelter use is related to weather variables (e.g., ambient temperature and wind speed) and insect harassment. The shelter-seeking behaviour was studied for three different groups of horses: Group 1) eight individually housed horses in paddocks that had access to three different shelter types (C: closed on three sides with roof, R: open on three sides with roof, W: closed on three sides without roof), Group 2) 25 group housed mares with foals on pasture with access to shelters C, and Group 3) ten mares without foals on pasture without access to shelter. Each group was studied for eight days.

Ekologiskt uppfödda kycklingar : en jämförelse mellan två olika foder

Organic rearing of broilers is not a large production in Sweden. In order to create a sustainable yet efficient production of organically produced poultry meat, at a price that the consumers are willing to pay, much more knowledge is needed. It is therefore important to do more research on organic broilers under Swedish conditions. This report is aimed to be a base for further studies. In the study 2000 broilers of the hybrid Ross 308 divided in to two equal groups. The broiler hybrids that are used in Sweden are selected for a high growth rate and are normally slaughtered at the age of 5 to 6 weeks, with a slaughter weight of 1.7-2 kg.

Vedrötor i stadsträd : biologi, detektionsmetoder och förebyggande åtgärder

Urban trees have very little in common with trees on natural sites, such as forests or pastures. Trees in urban environments are often planted in packed soil and in small volumes. This can lead to decreased availability of water and oxygen, as well as deteriorated ability for the soil to store nutritional elements. Also above ground the tree usually have limited space in cities. Regulations on free height over roads and cycle tracks demands high stems at an early stage of their development.

Implementation of renewable energy in the Republic of Moldova : society and landscape in transition

The Republic of Moldova, situated in eastern Europe and a former part of the Soviet Union, is now experiencing a phase of transition in both society and landscape. They have hardly any fossil depots and are currently dependent on Russian gas, with 97% of their energy needs imported. The new elected government wants to move towards the EU and this is generally seen as the way to grow and reduce poverty. Security in the energy sector is important and one tool is to increase the use of renewable energy sources. Through interviews, texts, and visits I have studied the implementation of renewable energies (RE) in Moldova through a society development perspective. The study has aimed to investigate the sociotechnical complexity of this subject and to discuss the potentials and way of dealing with the subject in the specific cultural context of Moldova.

Vindkraftens generationsskifte i Halland

Vindkraften expanderar allt mer i Sverige och årsproduktionen ökade till 6,1 TWh år 2011, vilket är en ökning med 74 % jämfört med 2010.De nya vindkraftverken som sätts upp idag är oftast av effektstorlekarna 2 000 ? 3 000 kW. De som restes tidigare är omkring 200 ? 600 kW. I Sverige finns det många vindkraftverk som har varit i drift under en längre tid, och det är flera som passerat sin tekniska livslängd på 20 år.

Val av fönster - En Multikriterieanalys

Fönster blir idag en allt viktigare del av en byggnads klimatskärm. Det ställs därför krav på olika funktioner vilka måste uppfyllas oberoende av fönstertyp. Då glas blir vanligare i moderna konstruktioner ställs det högre krav på värmeisolerande förmåga. Cirka 35 % av en byggnads värmeförluster sker genom fönster. Detta ställer krav på tillämpning av energieffektiva fönster vid ny- och ombyggnad. Underhåll av fönsterkonstruktionerna är en oundviklig detalj och måste ske någon gång under en byggnads livslängd.
