Simulation of rattan harvests in Indonesia : different harvesting pressures and the resulting patterns

The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.

Hållbar stadsutveckling? : Problem och målkonflikter i planeringen av Hagastaden och Norra Djurgårdsstaden i Stockholm

The major environmental problems that we have today are frequently mentioned in the media today. One example is the ongoing debate regarding global warming and its causes and consequences. There are also several other problems in our society such as segregation and social tensions. Most agree that we must do something to solve these problems and that we must try to achieve a sustainable development for the entire planet. But how should it actually be done and what trade-offs, compromises, sacrifices and changes must be made?The purpose of this paper is to examine how these issues are being dealt with in Swedish city planning.

MIGRATIONSSTYRNING I EUROPA: MAKT, KV?VNING OCH KONTROLL En kritisk maktanalys av migrationsstyrning i Europa genom utrikes f?dda kvinnors arbetsmarknadsintegration i Sverige

In today?s Europe, migration has become a security issue rather than a humanitarian issue. Previous research highlights how migrants have become prisoners of bureaucracy in Europe by their mobility being hindered. The present study critically analyses the migration governance in Europe by highlighting labour market integration in Sweden. The study highlights migrants with a specific focus on foreign-born women. The research questions chosen to examine this phenomenon is: How does migration governance in Europe affect member states' policies for labour market integration, with a particular focus on Sweden? How do foreign-born women in Sweden experience labour market integration processes within the framework of the governance mechanisms that exist in Europe? Foucault?s theory of power and the theoretical concept of choking composes a theoretical framework which is used to analyse focus group data and text analysis data.

ANALYS AV FLYTTSTRÖMMAR -En studie om migration och platsattraktivitet

Migration är resultatet av en växande globaliserad ekonomi och ett utökataktivitetsmönster vilket ställer högre krav på individens rörlighet. Migration bidrarbåde med för- och nackdelar för samhällsutvecklingen i ett land, en region och på enplats. Ur ett kulturgeografiskt perspektiv studeras migration utifrån vilkaomständigheter och förutsättningar som ligger till grund för uppkomsten avflyttströmmar, så kallade push- och pullfaktorer. Push- och pullfaktorer kan kopplastill vad det är som gör en omlokalisering eller en plats attraktiv, vilket stärkerplatsattraktiviteten genom områdesfaktorer. Dessa områdesfaktorer påverkaruppfattningen om platsens kapacitet och de resurser som finns tillgängliga för attfrämja en fortsatt befolkningstillväxt samt hur platsen påverkas avbefolkningsförändringar som uppstår i och med migrationsprocesser.

Avledning av öringsmolt (Salmo trutta) från turbinintag

Vattenkraftstationer, med dammar och turbiner, utgör hinder för nedströmsvandrande smolt. Syftet med denna studie var att undersöka turbindödligheten för öringsmolt (Salmo trutta) vid två kraftstationer, de befintliga ytlänsarnas avledningseffekt och om effekten kunde förstärkas genom mörkläggning i form av övertäckning av kraftkanalen med en presenning vid turbinintaget. Utöver detta var avsikten även att undersöka om det fanns något samband mellan smoltgrad och smoltens förmåga att förflytta sig mot havet. I Emån i Småland fångades 46 öringsmolt som radiomärktes och sattes ut vid två kraftstationer och pejlades dagligen i sex veckor. Det var en större dödlighet vid den övre stationen än vid den nedre.

Den Bortglömda Kanalen

The matter of CSR and sustainable products has gained an increased amount of interest in recent years as "green products" are becoming a trend with more "eco"-alternatives in the assortment of many retailers. However, among the increasing number of socially oriented customers, it seems that although they claim an increased demand for these kind of products, its easier to "talk the talk" that to actually "walk the walk". This is due to a discrepancy between attitude and behavior, called the attitude-behavior gap. The purpose of this paper is to examine how to overcome this gap by using three different studies to get a nuanced and reality-based view of the problem. The focus within these different studies is on the potential effects inside the store and how information provided has an effect on perceived credibility and purchase intention.

"AVRÄTTAS ej BENÅDAS" : en kvalitativ studie av migrationsmyndigheternas bedömning av synnerligen ömmande omständigheter i ärendena för sex funktionshindrade migranter

This study is aimed to increase the knowledge about the Swedish immigration authorities? assessment of the asylum applications based on particularly distressing circumstances, submitted by disabled undocumented migrants. Making an attempt to explain the reasons of asylum-seekers? health deterioration during the asylum process, this study determines the factors in migration authorities proceedings affecting such deterioration. Documents in five personal files concerning six disabled asylum-seekers, whose applications were declined, were studied by applying two observational methods: content analysis of the documents in the personal files and non-participant observations made during receptions of undocumented migrants at the Swedish Asylum Committee.

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.

Den ekonomiska tillväxten : en redogörelse för pessimistiska och optimistiska synsätt

The economic growth we have experienced the last century is based on limited natural resources. Whether these resources will last for a further economic growth is widely debated. Pessimism and optimism have each been influential philosophies in debate whose opinions can be conceded as two opposing opinions. In this paper we have analyze these opinions from an economics perspective. To study this further, the construction and meaning of the pessimistic and optimistic arguments have been applied implicitly on the Leontief production function and the Solow growth model.

Hållbart jordbruk inom vattenskyddsområde : En studie om Sverige, Danmark, Frankrike och Tyskland

To guarantee protection of our drinking water, water catchment protections are established. These are divided into three different zones and in the first zone it is most likely that an activity, such as agriculture, will contaminate the water resource. Hence the activities are strongly regulated or banned. The EU communion is working towards a sustained water quality through several directives; Nitrate Directive, Waterframwork directives and Sustainable use of pesticide directive. The main purpose is to regulate the diffuse pollution from agriculture.This thesis is about how Denmark, Germany and France are working towards a sustainable agriculture within water protection areas.

Hållbar vattenkraft i Nissan : En förstudie och konsekvensutredning över förutsättningarna för ökade vandringsmöjligheter med nya fiskvägar.

The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.
