Climate variability and its implication for water resources and livelihoods in Uganda

Nsubuga, F.W.N. (Francis Wasswa Nkugwa) January 2013 (has links)
This thesis examines the climatic trends of rainfall and temperature in Uganda using historical data. And because climate is an important aspect in water resources management and livelihoods formation, an attempt to explain how the interaction impacts on the two is made in the context of climate variability and change. The assumption is that climate change/variability has had an effect on water resources management and the way individual, households and society at large form livelihoods in Uganda. The rationale for the investigation is the number of climate and livelihood related studies that have been undertaken for Uganda over recent years, which have not focused specifically on the water resources management and livelihood formation. The study is grounded by reviewing the theoretical perspectives of climate science which underpin the concepts of climate change, climate variability and impacts on livelihoods in the world, tropics, Africa, east Africa and Uganda in that order. A cross sectional research design based on selected case studies from sub-counties located in the main sub-basins across the country is used. Both qualitative and quantitative data analysis techniques are applied independently or in combination on climatic data from Uganda‟s Department of Meteorology, data generated from field interviews and landsat images. The data sets are analysed using MS EXCEL, SPSS, MATLAB, ANCLIM, TREND TOOL, GIS and ENVI 4.8 to establish climatic trends and deduce evidence of change and variability. The impact on livelihood formation is investigated through the assets available to the households using the DFID framework. The study therefore has investigated the characteristics of climate in Uganda especially by following up on the responses that arose from the field study. Through their own observations, respondents noticed changes in temperature and rainfall. Temperature variables like diurnal temperature range, maximum and minimum temperatures and rainfall (monthly, seasonal, annual) have been investigated, to establish whether these observations were impacting on livelihood formations and water resources which are central in the wellbeing of individual households. Results show decadal variability of rainfall with marked seasonal cycles, temporal variability of drought patterns is detected; variations in annual rainfall are low with no significant trends observed in the main drainage sub-basins. Significant trends occur in October, November, December and January. A noticeable decrease in the annual total rainfall was observed mostly in north-western and south-western sub-basins. Rainfall trend in the second normal of June-July-August (JJA) is decreasing in all the main drainage sub-basins; highest rainfall was recorded in April, while January, June and July have the lowest rainfall. Spatial analysis results show that stations close to Lake Victoria recorded high amounts of rainfall. Average annual coefficient of variability was 19% signifying low variability. Rainfall distribution is bi-modal with maximums experienced in March- April- May and September- October- November seasons of the year. PCI values show a moderate to seasonal rainfall distribution. FNW Nsubuga – University of Pretoria Page 11 Spectral analyses of the time components reveal the existence of a major period around 3, 6 and 10 years. Intra-annual temperature show reduced variability over recent decades, which is not statistically significant. Maximum temperatures are more variable compared to minimum temperatures in Uganda. An increasing trend in hot days, hot nights, warm nights and warm spells are also detected. At seven of the stations, annual temperature range and diurnal temperature range trends are negative. The finding that intra-annual and intra-monthly variance is declining suggests that fewer anomalously extreme temperature episodes occur. The gap between maximum and minimum extremes is reducing, which supports the observation that minimum temperatures are on the increase. At a micro-level analysis using Namulonge as a case study, total rainfall in March-May season decreased, while maximum temperatures increased between April and September, with statistically significant trends at 5% confidence level. The Mann-Kendall test revealed that the number of wet days reduced significantly. Temperatures are warmer and rainfall higher in the first climate normal compared to the recent 30 years. Direct rainfall, which is the most important source of water for water resources, recently, is experiencing variability, which is threatening the distribution of water resources in Uganda. The characteristics, availability, demand and importance of present day water resources in Uganda as well as the various issues, and challenges pertaining to management of water resources of the country are established. The present analysis reveals that surface-water area fluctuation is linked to rainfall variability. In particular, Lake Kyoga basin lakes experienced an increase in surface-water area in 2010 compared to 1986. This work has important implications to water resources management and people whose livelihoods depend on natural resources especially in this era of climate change. Evidence from the field survey validates what data analysis reveals from historical data. Respondents from the field study are aware of climate change, had noticed some changes in climatic variables and were adapting by changing lifestyle and diversifying to activities that are less prone to weather. Livelihoods in Uganda have evolved based on the availability of opportunity afforded by the natural resources base including water resources. / Thesis (PhD)--University of Pretoria, 2013. / gm2014 / Geography, Geoinformatics and Meteorology / unrestricted

Evaluation of productivity and quality performance in a newspaper preprint insertion process

Bonaplata, Javier 22 October 2009 (has links)
Productivity and quality of a manufacturing process are seen as important factors for short and long term success of a company. Measuring productivity and quality provides the means to assess performance trends of the process, providing a powerful management tool for decision making. Data Envelopment Analysis is a tool that can be used to measure productivity and quality performance. Productivity and quality performance were measured using Data Envelopment Analysis for a newspaper preprint insertion process. Hybrid performance models combining productivity and quality performance were also evaluated using Data Envelopment Analysis. Finally, the possible underlying relationship between productivity and quality was investigated. The major findings of this research are: * Productivity and quality performance trends obtained from the study provide realistic assessment of performance of the newspaper preprint insertion process. * The trends of the hybrid performance models were not able to accurately assess the performance of the newspaper preprint insertion process. * There does not seem to be a link between productivity and quality in the newspaper preprint insertion process for the time period studied. / Master of Science

An exploratory study of trending talent acquisition tools and techniques in the South African context

Naidu, Dashalia January 2019 (has links)
The review of talent acquisition tools and techniques used in South Africa is not widely available in literature. To implement and utilise appropriate tools and techniques to foster talent acquisition and maintain competitive advantage in this regard, organisations need to keep their finger on the pulse. Therefore, the subsequent research aimed to provide greater insight. The purpose of the dissertation was to review current literature on global trends of talent acquisition tools and techniques, thereafter provide insight on the trending tools and techniques used in the South African context. Along with the reported trends, their impacts and best practice were reviewed. Due to the dire need for South African context-based research on talent acquisition tools and techniques used, this study reports on empirical results as informed by some of South Africa’s largest insurers. The empirical results were obtained by using a qualitative research method with an interpretative approach. Qualitative surveys in the form of semi-structured interviews were used as the data collection tool to extract the relevant information from the three participating organisations. Thematic analysis was used to thoroughly analyse and structure the raw data. The main findings reflected that each organisation makes use of talent acquisition mechanisms as they see fit with a steady incline in the use of digital and online tools and techniques. The impacts and best practices and policies applied are further discussed although the consensus leans towards reasonable accommodation and emphasis on diversity and inclusion. The dissertation contributed to talent acquisition practices as the empirical findings reflected practices which are relatable and representative of similar organisations’ current way of work. More so, the literature reviewed is current and informative. / Dissertation (MCom)--University of Pretoria, 2019. / Human Resource Management / MCom / Unrestricted

In search of fear : A study examining the potential of using Google Trends data to estimate the fear of crime in Sweden during 2011-2019

Lindberg, Karl January 2020 (has links)
Fear of crime is an important topic in research as well as in public opinion. However, data on fear of crime is limited and difficult to collect, being heavily reliant on surveys with different methods of operationalization yielding different results. This paper aims to investigate if an alternative method can be used to estimate fear of crime. Using a large representative unique data on fear of crime from Google Trends, I analyze if fear of crime can be estimated in Sweden during years 2011-2019, using The Swedish Crime Survey as benchmark. The results show that the method is accurate for country-level and the most populated regions of Sweden, but less so for the lesser populated regions. This method can be used to estimate fear of crime in a time- and money-efficient way, producing daily estimates at little to no cost.

Vliv behaviorální pozornosti na cenu akcií bank

Čajka, Ondřej January 2018 (has links)
This diploma thesis is based on the theory of behavioral attention and examines the effect of the search for negative words in conjunction with the name of the bank on the price and on the yield of the shares of these banks. As a sample, 12 global, publicly traded and significant banks were selected. In this work, the behavioral attention is identified as the level of search on Google. The panel regression with random effects is used in the work, and Bayesian Model Averaging is used to identify suitable variables. The data proves the effect of negative behavioral attention, when an increased level of attention diminishes yield and share price. The results are then subjected to a robustness analysis where the impact of behavioral attention is examined before, during, and after the financial crisis. Furthermore, the effect of regulation and the level of behavioral attention itself is examined. The diploma thesis corresponds to the knowledge of behavioral economics and confirms a certain irrational behavior of investors on the market.

Populační trendy živočichů různých taxonů a regionů na základě Living Planet Database / Population trends of animals of different taxa and regions on the basis of the Living Planet Database

Váňová, Lenka January 2021 (has links)
The analysis of population trends of animals is increasingly being used not only as an indicator of population changes, but also as an indicator of biodiversity decline. Living Planet Index is one of such indicators, as it shows a proportional decline or increase of all populations by means of mean annual changes in population abundance. Since the first presentation of the index in 1998, its values have been decreasing, which was interpreted as indication of a critical state of global biodiversity. Nevertheless, there are some issues concerning the index. It is unclear to what extent is it robust, if it is not too much influenced by biased data or if it does not comprise a systematic error. This thesis focuses on four vertebrate taxa and its aim is to examine the level of data heterogeneity and their potential influence on the index. For this purpose, two parameters were defined for each population, Growth and Trend. Overall, the trends in abundances were quite balanced, some populations being decreasing, some increasing, and stable populations were also present. Despite of our expectations, the heterogeneity in the data was not large enough to have a substantial effect on the index. Analysis of trends in variously defined groups (e. g. "biomes", taxa or biogeographic realms) revealed only little...
