Opportunities for improved environmental sustainability of a wine producer in South Africa : natural resource management and climate change adaptation and mitigation
South Africa has been among the top ten wine producing countries for at least 20 years. Even though the land under grapevines is decreasing globally it is still increasing in Africa. The awareness of environment has strengthen the last years and South African producers experience a high demand of environmentally friendly produced wine, especially from the European market. This demand was the driving force behind the development of the world unique sustainability certification, Integrated Production of Wine (IPW), which is inscribed in the South African legislation. What makes this certification unique is that consumers can trace their product all the way back to the farming practices owing to the identity number specified on the IPW Integrity & Sustainability seal on certified products.
Jordbruk och mjölkproduktion med kor i Etiopien :
Ethiopia is the country with most livestock per capita on the continent of Africa. There are 34.5 million cattle that are used for drought, meat- and milkproduction and 85% of the population rely on agriculture for their survival in some way. Milk is produced in four main systems, through pastoralism in the lowlands, in mixed crop-livestock systems in the highlands, in and near big cities with only one or two cows, and in intensive farming systems. There are 17 cattle breeds in Ethiopia and some of them are more suitable for milk production than others. Several environmental and economic problems arise from livestock holding in the country, for example overgrazing, low production due to feed shortage, low quality of the avaible feed and non-existing breeding programs.
De tre civilisationernas kontinent - En studie om Sydamerikas civilisationer i en globaliserad värld
In this thesis I analyse civilizations in South America. I construct civilizationalnarratives through the method of emplotment, to build a historic continuity, whichI subsequently connect to the theoretical framework. The theory emphasise that,when confronted with globalization and free market capitalism, civilizationsembark on different strategies to challenge the power of transnational marketforces. I find that South America is a polarised continent, and is divergingconcerning the relationship towards the USA and free trade agreements. On thesame time the issues that concern the social movements are not being reproducedin a significant matter at state level.
Porcine viruses in Uganda : a study of TTSuV and PPV4 in wild and domestic pigs
Uganda has the largest pig population in east Africa, and most of the animals are owned by smallholders. Infectious diseases among pigs have a devastating impact on the livelihood of these farmers, which are dependent on the proceeds from pig rearing. In a metagenomics study of the wild pig species bushpig (Potamochoerus larvatus), the porcine viruses Torque teno sus virus (TTSuV) 1and 2 and Porcine parvovirus 4 (PPV4) were detected. TTSuV1 and 2 are ubiquitous in the world?s swine population, and PPV4 has been found in USA and China, but neither of them has been studied in Africa previously.
Luftvägssjukdomar bland konventionella och ekologiska slaktgrisar
Luftvägssjukdomar är ett av de största hälsoproblemen bland dagens slaktgrisar. Problemet har ökat i takt med att besättningsstorlekarna och därmed smittrycket har ökat. Spolmask i närvaro av en ett annat smittämne som till exempel Mycoplasma hypneumoniae kan orsaka luftvägssjukdomar. Spolmask är en av de vanligast förekommande parasiterna hos gris och orsakar bland annat skador på grisens lungor. Det är ett problem bland såväl konventionella som ekologiska slaktgrisar.
Kan olika virussjukdomar blockera varandra? En studie baserad på övervakningsdata
Background: Infectious Diseases Institute points out that the potential of various viraldiseases possibly can block each other. It is said that the virus that causes common cold,Rhinovirus, may have saved many people from the flu. If this assumption proves true, itwould explain why some viral diseases in some countries have been slow to take off and pointto a new way to struggle influenza. Objective: The main purpose of this study, based onreported cases of RSV and influenza type A, type B and H1N1, investigate whether viraldiseases can block each other, i.e. difficult season of flu may delay and / or mitigate thespread of RSV in Sweden.
Gårdsbaserad biogas på Nya Skottorp : utvärdering och optimering av anläggningen och uppgradering av biogasen
Biogas is an expanding sector within the broad field of agriculture and animal production. Small-scale biogas offers local combined power and heating production and the substrate is transformed into high-quality biological fertilizer. This bachelor thesis focuses on a pig farm in south-western Sweden, where biogas is produced from pig manure, evaluates and suggests ways of optimizing the process and investigates whether investing in an upgrading plant would be a feasible and more cost-efficient option. The results show that the biogas plant is working well, although the production differs from the original plans. This shows in turn that planning and examining the basic conditions before making the investment is of great importance, as well as monitoring and keeping detailed statistics of the running process.
Monitoring lion movements
Prevention of lion predation towards African livestock is of great importance due to the economical losses farmers have because of this. Predation is also one of the main reasons for human-wildlife conflicts and lions often get killed because of it. Therefore, a pilot study using camera traps was conducted to monitor movements of lions and other wildlife through a wildlife corridor in Ol Pejeta Conservancy. The results were compared with a previous study that counted prints in the soil in front of the corridor. Due to theft risk the cameras had to be taken down and pictures were only collected from nine days.
Nattaktivitet hos Afrikanska elefanter (Loxodonta africana) i fångenskap med olika kombinationer av miljöberikning
African elephants (Loxodonta Africana) are kept all over the world in different kinds of enclosures. The enclosures are however often unsuitable for the elephants. Research has shown that elephants are nocturnal animals. Therefore it is important to keep elephants occupied, for instance by using enrichments, also at the night.
Five elephants were studied at Borås djurpark, four elephants in one room and one elephant, named Nyoka, in one room.
Mina elever är mina resurser : En jämförelse av hur verksamma lärare arbetar med läsundervisning i Sverige och Sydafrika
The purpose of this study is to investigate the teaching of literacy in two schools in different countries, South Africa and Sweden. The basis for the comparison was the decline of the two countries in the international PIRLS assessment. The aim of this essay was thus to identify possible similarities or differences between the two countries, possibly contributing to the decline in the literacy level of young students. The study was conducted by interviewing teachers of young children in South Africa and Sweden about their views on teaching literacy. The research shows that there are several factors contributing both positively and negatively to the literacy of young children.
Improvement of positive strand assay used in detecting positive and negative RNA of hepatitis E virus
Background: Hepatitis E (HEV) is a small, non-enveloped virus that belongs to the viral genus Hepevirus. HEV is a positive sense single-stranded RNA virus and there is insufficient information regarding its replication. This is mainly because the virus has low capacity to grow in normally used cell cultures. Many specific strand assay detection studies have been done in order to understand more about HEV replication. Unfortunately, these assays have the disadvantage of giving false positive results.Aim: The aim of this project was to improve the positive strand assay to increase specificity and eliminate false positivity which is due to high sensitivity of the polymerase chain reaction (PCR).
Epidemiology of viruses in the livestock in Tanzania : a minor field study with focus on Peste des Petits Ruminants virus
Peste des Petits Ruminants (PPR) is a disease of major socioeconomic impact. It is an acute and highly contagious viral disease of small ruminants caused by the agent Peste des Petits Ruminants Virus (PPRV), a Morbillivirus closely related to Rinderpest virus (RPV) which was declared eradicated from the world in 2011. PPR has a high morbidity and mortality rate and is characterised by high fever, nasal and ocular discharge, pneumonia, necrosis and ulceration of the mucous membranes and inflammation of the gastrointestinal tract causing severe diarrhoea. The role of wildlife in the epidemiology of the disease is still unclear. The disease is currently affecting sheep and goat in 70 countries worldwide and this year (2014) FAO has announced a program to eradicate the virus by 2030.
In Tanzania, the disease was first reported in 2008 and has since then spread to different parts of the country.
?detta Otrevliga klientel? : En studie av de flyktingar som vårdades i Växjö mellan åren 1944 -1947.
?this Unpleasent klientel?A study on refugee care in Växjö between the years 1944 and 1947.The purpose of this study was to examine the treatment of sick refugees in Växjö in the 1940s. To achieve this a combination of quantitative and qualitative methods were used. The material found in the local archive and local newspaper was then put together and analyzed from the theoretical perspective, gender, class, ethnicity and social status.The result of this study shows that there were two main treatment wards for refugees, one that was supposed to treat women and children with active tuberculosis and the other ward treated refuges with ?epidemic diseases.? Foreign citizens were also taken care of in other words that were also not meant for refugees only, like the Epidemic hospital, which treated about 80 patients of a foreign nationality between 1944 and 1946.
Regional frihandel med miljöhänsyn? En studie av regionala frihandelsavtals förhållningssätt till konflikten med miljön
The relationship between free trade and the environment is often considered conflicting and the debates surrounding it are infected. My thesis deal with this conflict and how environmental concerns are integrated in three regional free trade agreements, North American Free Trade Agreement, The common market of the southern cone (MERCOSUR) and Southern African Development Community (SADC). I point out how the organizations differ from each other in this respect and I present a possible explanation to why they differ. The explanation is founded on the theory of the environmental Kuznets curve and that environmental concerns will depend on which level of development the member states in the organizations have. To judge and rank the organizations I have composed a model based on a pre-existing description of the trade and environment conflict.
