Published Article / The central regions of South Africa experienced an abnormally high precipitation during the first quarter of 2009, thus resulting in an unusually high probability of veld fires due to the excessive amounts of fuel / grass available. In South Africa the process of land redistribution was recently drastically accelerated. This implies that many newly settled black farmers are fanning but still need to be trained in various aspects of farm management. Unfortunately, in most cases this training did not include environmental management, which among others, implies managing and preparing for veld fires. The Department of Water Affairs and Forestry also does not have sufficient funding to cover all these aspects and a regional collaborative plan must therefore be developed. In addition to this, in an attempt to alleviate poverty, many other previously disadvantaged people in South Africa must be assisted in establishing small business enterprises. This paper will highlight a process to be followed to train and coordinate all farmers and simultaneously establish business opportunities that will remove some of the fuel (grasses and shrubs) in order to reduce the risk and intensity of winter and spring veld fires.

Increased access to energy is a key factor to reduce poverty and to gain increased development and prosperity. Access to energy is not equally distributed globally. On average a Swedish person consumes more energy than 12 individuals in Tanzania. The Msambara village arose in the 1930s. 80% of the inhabitants are children and the families are large. Life expectancy is 52 years for women and 54 for men. The entire region is very poor and the standard of living in Msambara is low, even compared to other parts of the country. In rural Msambara in Tanzania the cooking method is very primitive and is usually carried out indoors on three stones. Indoor pollution is contributing to eye infections. Incomplete combustion not only emits greenhouse gases increasing global warming, but also more directly emits particles effecting human health. Women and girls are particularly vulnerable to burning caused by air pollution, especially since they are responsible for cooking. The women pull a heavy load in the household work. They are responsible for raising and caring for children, managing farms, collecting firewood, fetching water, visiting the market and cooking for the family. The adoption of biogas technology reduces the need for traditional energy and thereby reduces environmental degradation. In addition, the residue is an improved agricultural fertiliser. Biogas technology has social considerations; burning of biomass for cooking reduces indoor air pollution and reduces workload to collect firewood, often performed by women. Moreover, biogas is desirable from an economic point of view. The method in this work can conveniently be divided into three different parts. These are the designing and construction process as well as the socio-economic study. The socio-economic component is split into two different sections, which are field study and data modelling. The study shows that the social negative impact may or may not be reduced by the introduction of the biogas facility, but the biogas facility in the way it is made will potentially contribute to sustainable economic growth for the household. It also shows that the household’s organic waste produced from human, animal, kitchen and garden waste is enough to provide the necessary gas needed for cooking and no additional firewood will be needed. Two diary cows, in addition to the household’s waste, will provide enough gas needed to introduce cooling capacity for food storage. By adding cooling capacity in the household, time will be saved from the food preparation process but the introduction of biogas itself will not reduce the individual work burden when no cooling capacity is installed. The study also shows that placing the digester in the ground makes a stable environment for the mesophilic and methanogenic microbes. The Socio-economic study indicates that by introducing an alternative method to cooking, positive health effects will arise and the household benefits economically. It is not possible from this thesis to conclude that by adding and treating human toilets as a substrate that possible health benefits will take place. / Sammanfattning Ökad tillgång till energi är en nyckelfaktor för att minska fattigdom och för att få ökad utveckling och välstånd. Tillgången till energi är inte jämnt fördelad globalt. En svensk person konsumerar i genomsnitt mer energi än 12 individer i Tanzania. Byn Msambara uppstod på 1930-talet, 80 % av invånarna utgörs av barn, familjerna är stora. Medellivslängden är 52 år för kvinnor och 54 år för män. Hela regionen präglas av fattigdom och levnadsstandarden i Msambara är låg, även jämfört med andra delar av landet. I Msambara som ligger på Tanzanias landsbygd är tillagningsmetoden mycket primitiv och utförs vanligen inomhus på tre stenar. Den rökiga inomhusmiljön leder ofta till ögoninfektioner. Den ofullständiga förbränningen frigör inte bara växthusgaser och bidrar till den globala uppvärmningen, utan mer direkt avges partiklar som påverkar människors hälsa. Kvinnor och flickor är särskilt utsatta för luftföroreningar eftersom de är ansvariga för matlagning. Kvinnorna drar ett tungt lass i hushållsarbetet. De är ansvarig för uppfostran och vårdnaden utav barnen, hushållsarbetet, sköta jordbruket, samla ved, hämta vatten, besöka marknaden och att laga familjens mat. Introduktion av biogasteknik minskar behovet av traditionell energi och miljöbelastningen. Rötresten är dessutom ett förädlat gödningsmedel. Biogas introduktionen ger positiva sociala konsekvenser då det leder till reducerade luftföroreningar inomhus och minskar behovet av att införskaffa ved, vilket nästan undantagslöst utförs av kvinnor. Dessutom är biogas positivt ur ekonomisk synvinkel. Arbetsmetoden är tydlighetens uppdelat i tre delar. Nämligen dimensionering av rötkammaren, uppförandet av densamma och en okonstlad socioekonomisk studie som i sin tur är uppdelad i en fältstudie och simulering. Studien kan inte visa på att summan av de sociala negativa effekterna minskar med införandet av biogasanläggningen men däremot att den potentiellt bidrar till stärkt ekonomi för hushållet. Den visar också att hushållens organiska avfall som produceras i form av avfall från människor, djur, kök och trädgård är fullt tillräckligt för att producera den nödvändiga gasen som behövs för matlagning. Ingen ytterligare ved kommer att behövas. Två kor förutom hushållets avfall ger den biogas som krävs för att driva ett kylskåp vilket ökar hållbarheten vid matförvaring. Genom tillförandet av kyleffekt till hushållet frigörs tid vilket innebär en tidsbesparing. Införandet av biogas i sig minskar inte den individuella arbetetsbördan. Studien visar också att placeringen av rötkammaren i marken utgör en stabil miljö för de mesofila metanogena. Den socioekonomiska studien visar att införandet av den alternativ matlagningsmetoden medför positiva hälsoeffekter och är ekonomiskt gynnsamt för hushållet. Från denna studie är det inte möjligt att dra slutsatsen att tillförandet och behandlingen av den mänskliga toaletten i rötprocessen ger hälsofördelar.

New Zealand wood availability forecasts indicate that increases in the future wood availability significantly relies on small-scale forest owners' resources. This "small-scale" resource is poorly understood and comprises a large number of owners. It is questionable how many of these forests are established with consideration of the cost and practicality of harvesting. An improved understanding of the likelihood of this resource ever being harvested is important for understanding future wood supply. The main objective of this study is to answer a fundamental question on how much small scale forest area is economic to harvest. The study aims to estimate the basic stumpage value of the forests at modelled costs and different log price levels, and to analyse the profitability of the small scale forests by looking at the historic rate of return, as well as the net present value (NPV) and internal rate of return on existing and future forest land. The emission trading scheme (ETS) was also taken into account during the analyses and the effects of the ETS on the profitability, optimum age and future wood availability were investigated. The methodology developed for this study uses a forest growth model (Radiata Pine Calculator), Geographic Information Systems, the Visser harvest cost model, and Microsoft Excel. The growth model enables the analysis to be customised to a specific region of interest, while spatial characteristics such as slope and transportation distance of individual forests were taken into account by using GIS. The cost model allows the analysis to be customised to individual forests to some extent although a number of assumptions are made generalising the forests as whole. Developing the overall framework within Excel allows easy analysis of the results and changes to the underlying assumptions. Harvesting and transportation costs are the main drivers in determining the profitability of small scale forests. A significant increase in log prices is required for the existing forests to obtain substantial profit from log production. At current log prices 90% of small-scale forests in the Wanganui District are economically available. The other 10% small blocks on steep sites, have negative stumpage revenues because of high harvesting costs. Additional cashflows from entering the ETS have the potential to generate significant revenue for post-89 forests. However the substantial increases in optimal rotation age are likely to delay the increase in harvest volumes forecast from the small-scale estate.

Some of the key elements to assess the status of any wildlife population in a given geographical area are the levels of recruitment, survival and mortality. Whilst most of the information on marine turtles has been obtained from nesting sites, turtles spend most of their lives at sea. The conservation status of marine turtles in the southeast Pacific is poorly documented. This is particularly true for countries like Peru, where nesting events are very rare, although five species of turtles from populations from all over the Pacific basin, use these waters as foraging grounds. Little information exists on the threats to turtle populations in foraging areas or the magnitude of these impacts. Small-scale fisheries are a globally important economic activity serving as a source of food and employment for ca. 1 billion people; however we show that they also have serious impacts on marine turtle populations from all over the Pacific basin in the form of incidentally captured marine turtles. The five chapters that constitute this thesis are intended to increase our understanding of small-scale fisheries impacts on this taxon during their aquatic life stages. This work focuses on describing these fisheries, their impacts on marine turtles and proposes methodologies to monitor and assess the level of bycatch from small-scale fisheries. We also discuss alternative ways to prevent fisheries interactions and promote the involvement of artisanal fishermen in the southeast Pacific in implementing conservation solutions.

The aim of this research was to discuss about event management theory and how the Liiga (the major ice hockey league in Finland) team organisations could use this theory to improve their home game events. This topic has been divided into two research questions from which the first discusses the current situation and the other gives suggestions for future improvements for the Liiga team organisations. This research is conducted as a master’s theses and it has been conducted in years 2014 to 2016. In order to understand the research topic the general theory of event management has been told from the sporting event point of view. This theory has been divided into two different sections which are the five stages of event management and the operational strategies of event management. Answers for the research questions have been search with a qualitative research and its methods of interview and questionnaire, observation and content analysis. These methods and the way these have been used in this research are introduced after the event management theory. The data collected with the selected qualitative research methods has been introduced as empirical findings. These empirical findings are introduced a research method at a time and in a same order as the data has been collected. After introducing the collected data it has been carefully analysed. The analysis have also been divided into two section from which the first answers to the first research question concerning the current situation and the other the second questions concerning the future improvement that could be done. The first part of analysis has been made in a same chronological order as the event management theory has been written in order it to be easy to compere these two to each other. In the end the conclusions of this research and its research questions are introduced. Also the knowledge which this research is offering for the tourism industry and for its readers have been discussed. This are also a lot of different ways how this research could be continued and made further and these ways have been discussed as well. Last but not least the research has been viewed critically and the quality of it has been questioned.

This commentary accompanies a portfolio of nine compositions written between October 2006 and June 2009. This commentary traces the development of a range of compositional ideas throughout the portfolio. These revolve around the creation of multilayered textures where all the material and all subtle variations thereof are audible, leading to an investigation of rhythmical block durations and the role of memory. The context in which these ideas arose is provided through discussion of specific existing work that closely relates to the portfolio, in particular by John Cage, Morton Feldman, György Ligeti and Giacinto Scelsi.

A pesquisa é focada na aplicação de métodos indiretos de exploração mineral no planejamento de lavra em mineração de pequena escala (MPE). O objetivo é demonstrar o potencial de contribuição dos métodos geofísicos no planejamento de lavra. Para isso, foi desenvolvida uma nova metodologia para seleção e aplicação de métodos geofísicos e foram realizados experimentos conduzidos em três depósitos minerais, um de ouro, um de manganês e um de calcário, em que os métodos geofísicos testados apresentaram contribuições efetivas para o planejamento de lavra na MPE. Nos três experimentos realizados, foram utilizados métodos geofísicos de eletrorresistividade e de polarização induzida, com técnicas de sondagem elétrica vertical e de caminhamento elétrico, para identificar as estruturas geológicas de interesse. Esses métodos permitem, de maneira geral, determinar a profundidade e a espessura da camada de solo e das estruturas geológicas de interesse no horizonte investigado. Os resultados da aplicação dos métodos geofísicos comprovaram que as informações geofísicas permitem acelerar o processo de tomada de decisão no planejamento de lavra, pois reduzem o tempo e os custos associados à pesquisa mineral e à modelagem geológica utilizada no planejamento de lavra da MPE. / This research focus on the application of indirect methods of mineral exploration to support decision-making during mine planning of small-scale mines. The objective is to demonstrate the potential contribution of the introduction of geophysical methods to the mine planning cycle. A new methodology is proposed for selecting and applying geophysical methods in small-scale deposits in order, to test its impact in the mine planning process. The methodology has been applied to three small-scale deposits of gold, of limestone and of manganese ore. The selected geophysical methods were electro-resistivity and induced polarization, with vertical electrical sounding and electric mapping techniques in order to identify the geological structures of interest. In general, the selected methods allowed the gathering of quick and precise information of the depth and the thickness of the geological structures within the investigated horizons. The results obtained in the experiments have proven that the incorporation of geophysical methods allow for faster decision-making in the mine planning process of small-scale mines because they reduce the time and the costs associated to the acquisition of geological information in small-scale mining.
