Grönskan i Staden : grönstrukturens utveckling, funktioner & innehåll

The report by Boverket (2004), Hållbara städer och tätorter i Sverige - ett förslag till strategi says that large and somewhat intact green areas are better than severalsmall. Linking rural natural areas with the city's green areas, improves the opportunities for recreation and biodiversity (Boverket 2004). To create this, there isneed for a green structure in the city and its surroundings. But how to create this structure and what are the problems with the green areas in the city today? Thescenario that more and more people choose to settle in urban areas is a trend which not appears to decline, and at the same time our green spaces in cities and ruralareas decreases (Boverket 2007).

Det medeltida Visby : en kritisk studie av disskusionen om stadens etablering

Visby is a city that at first glance is of medieval origins. The popular image of scientists today is that the city was formed in the Middle Ages. According to some of the researchers Visby was formed during the Viking Age, it is based on the basis that the area has been used for a long period. Urban development in the Nordic countries is complex and there are different opinions as to why the Nordic cities emerge. It is important to shed light on the underlying process on why cities are emerging to provide clarity as to why Visby city is emerging.

Riksintressen för kulturmiljövården. Kritisk genomgång av fördjupade riksintressebeskrivningar

In Sweden, the main responsibility for urban planning lies with the municipalities. The county administrative boards are responsible for clarifying the governmental interests for the municipalities. The main purpose of this essay was to study documents with descriptions of national heritage areas in order to examine whether certain problems within these documents are still present in the most recent ones. This was done by comparing old documents with new ones. The problem with these kinds of documents has been the lack of clarification of cultural values in national heritage areas.

Kartering av markföroreningar inom Skutskärs Bruk samt utvärdering av spridningsrisker enligt Naturvårdsverkets MIFO fas 2

With the prospect of future construction on the Skutskär Pulp Mill property, Stora Enso Fine Paper has initiated an investigation of soil contaminants and a risk assessment of these contaminants. A soil and groundwater investigation has therefore been conducted on an open area of about 16 000 square meters, situated between the current wood room and digester house. To be able to integrate this study into an investigation for the whole industrial property, the study has been carried out as a phase 2 study according to the Swedish Environmental Protection Agency?s Methods of Inventories of Contaminated sites (MIFO).The site investigation has involved soil and groundwater sampling, together with the analysis of heavy metals and organic contaminants. The degree of hazard posed by the contaminants, the level of contamination, the potential for migration of the contaminants, as well as the degree to which protection of human health and the environment is required in the area, have been weighed together for an overall risk assessment of the area with regard to human health and the environment.The investigated area was built up by filling in the coastal waters.

Hygienisering av torkat bioavfall

The main project Dry preservation of food waste from households includes a new technique concerning drying and storage of dried biowaste as well as a study of the sorting of household waste and further usage of the dried biowaste. A question asked in the project is, can the dried biowaste be used as a soil amendment? If organic waste is used as a soil amendment, precaution concerning hygienic safety risks has to be accounted for. The objective of this M. Sc.

Projektet är en strategi för att stegvis uppgradera och förstärka offentliga delar av Holma i Malmö, i takt med att området byggs ut med nya bostadskvarter. Arbetet tar sin grund i vikten av spontana och planerade möten mellan människor, utgående från möjligheterna i strukturen av ett bostadsområde från senare delen av miljonprogrammet. Punktvisa ingrepp innefattar ett Folkets hus, en cykelpump, ett område för urban odling samt tillförsel av lokaler för publika funktioner i marknivå..

Side effects of biological control agents in agriculture : does the bacteria Bacillus amyloliquefaciens affect the earthworm Aporrectodea longa?

Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

Utveckling av metod för erfarenhetsåterföring vid stadsbyggnadsplanering

The paper is a thesis made by three students in the engineering program at Jönköping School of engineering. The thesis was overseen by the urban planning office and features data from Jönköping County.The purpose of the thesis is to improve future central districts by improvement of work methods. The aim of this thesis is, through an evaluation of process mapping, develop a model for systematical work methods with better experience feedback in the urban planning. The following three questions have been answered:? How is the process mapping of the urban planning in Jönköping County built today and how did it affect the current district Kålgården?? How can the urban planning of Jönköping improve with a more systematical work method with better experience feedback?? How can critics elaborate the developed method to make it enough stable and in general applicable method to enforce on future districts?Literature studies and interviews were made to review the work methods of the office of urban planning as well as how their experience feedback works.

Utvärdering av urbana ekosystemtjänster: Verktyg och certifieringssystem.

Denna rapport behandlar utvärdering av urbana ekosystemtjänster på stadsdelsnivå. Eftersom ökad urbanisering leder till ökad belastning på urbana ekosystem är det viktigt att både exploatering och etablering av grönområden sker på ett hållbart sätt där ekologiska, sociala och ekonomiska faktorer inkluderas. Detta kan delvis uppnås genom att villkor i verktyg och certifieringssystem inkluderar aspekter för urbana ekosystemtjänster. Det undersökts hur certifieringssystemen BREEAM Communities och CASBEE for Urban Development samt verktyget Grönytefaktormetoden behandlar sådana urbana ekosystemtjänster. Analysen utgår från en föreslagen kategorisering av urbana ekosystemtjänster.

Staden i ord och handling :

What is a city? What do we mean when we describe something as urban? In what way should we build the city so that we can achieve a good environment for our own generation and for generations to come? These questions are constantly of interest and they are frequently discussed. It is also important to have considered these questions when working with city-planning. This essay contains a description of and reflections about the recurrent questions in today?s debate about the city and city-planning.

Reducerad jordbearbetning : en fallstudie

This is a study made because I would like to see how much money can be saved when reduced soil preparations is used. This is a case study, the farm is located in the north vest part of Skåne, Sweden. I have calculated with four different soilpreparation methods. Alternative 1: Conventional soil preparation, the way the farm is managed today. Alternative 2: Ploughing on depth of 12 centimeters, with a ridge packer followed with sowing. Alternative 3: Eco-tillage Alternative 4: Direct drilling The results of my study showes that Alternative 2 is the most profitable. Alternative 4 is very good if you see to dieselexpenses and hours of work, but the yield is far to low. If the numbers are further analized, it showes that in spring barley the differense between Alternative 2 and Alternative 4 is at a minimum. So if there is lack of time for one reason or another, this might be an alternative in spring barley. The differense in how the farm is managed today and the most profitable alternative in the study, Alternative 2 showes that it can be saved up to 60 940 SEK..

Markvattenhalt och temperatur i sandig jordbruksmark vid Ilstorp, centrala Skåne : en mätnings- och modelleringsstudie

Vinderosion på jordbruksmark har länge varit ett välkänt faktum trots att någon utförligare undersökning om dess omfattning och skadeverkan inte tidigare genomförts. Mot bakgrund av detta har därför ett nordeuropeiskt projekt, WEELS (Wind Erosion on European Light Soils), dragits i gång som syftar till kartlägga vinderosionen på sandig jordbruksmark i norra Europa och som man i slutändan hoppas ska kunna resultera i en vinderosionsmodell. Detta har genomförts med SOIL modellen, en matematiskt fysikaliskt baserad modell för simulering av vatten och värmeflöde i en skiktad jordmånsprofil..

En studie av Uppsala stads värmeö

The urban heat island is an area restricted to a city center where the temperatureis higher than its surrounding environment. The greatest temperature difference isfound at night when the weather is calm and the sky is clear of clouds. There are twomajor causes behind this phenomena and the first one is the use of energy forheating of houses. The heat leaks through the walls of the buildings and warms upthe surrounding mass of air. The second one is the use of building material whichstore the suns radiation on daytime and releases the heat during night.

Socialt kapital : en skörd från den urbana odlingen

Hur kan urban odling skapa nya sociala nätverk mellan människor och få dem att mötas i staden? Litteraturstudien har till syfte att undersöka vilka studier som gjorts kring urban odling och socialt kapital, med fokus på överbryggande socialt kapital. Begrepp som community garden, community, kolonilott samt socialt kapital förklaras inledningsvis för att skapa ett ramverk till litteraturstudien. Socialt kapital kan förklaras som nätverk och sociala kopplingar mellan människor, och överbryggande socialt kapital är då sådana nätverk mellan människor från olika grupper i samhället. En historisk återblick ges kring hur socialt kapital, med fokus på överbryggande socialt kapital, har skapats både i Sverige genom kolonirörelsen och i USA genom olika stadsodlingsprogram från slutet av 1800-talet och fram till idag. Därefter refereras ett antal studier som undersökt kopplingar mellan socialt kapital och kollektiv odling, samt ett antal studier som beskriver kollektiv och urban odling kopplat till nätverk och möten, utan att använda begreppet socialt kapital.

Demand and perception of fertilizer : among small-holder farmers in Kenya

Hunger is a problem in some parts of the world (www, FAO 1, 2012). The lack of food is often a result of insufficient knowledge in soil fertility management (Röing de Nowina, 2012). Ongoing hunger and malnourishment are quite prevalent in Sub-Saharan Africa and are often combined with poverty (www, FAO 1, 2012). Farming is the most common occupation in this area and the farms are often small-scale farms with subsistence crops and a few cattle. The farmers who operate these small-scale farms are economically a weak group.
