Community-based governance of artisanal fisheries, Ngazidja Island, Comoros

Hauzer, Melissa 30 September 2011 (has links)
Tropical small-scale fisheries represent the main livelihood and protein source for a substantial portion of the global population. Growing pressures on marine resources, however, have left many fishing communities faced with declining catches and increased environmental degradation. Effective management strategies and governance institutions are thus critically important. Conventional top-down, exogenous approaches to fisheries management have been ineffective in more traditional and small-scale fisheries. Yet, there remains little understanding of the effectiveness of alternative approaches and few studies offer feasible solutions for managers in lesser developed nations. This case-study of artisanal fisheries in the Comoros examines how effective local fishing associations are at managing common fisheries resources, and provides some understanding of the underlying characteristics of effectiveness. To do so, qualitative methods were used to collect data on fishing practices, local knowledge and beliefs, governance structures, and livelihoods in male and female fisheries in five villages on Ngazidja island. The results of this study are organized into three papers. The first paper focuses on current fisheries trends on Ngazidja and the implications of the gradual shift from traditional to modern fishing practices. This paper contributes to the overall goal of this study as the modernization of the fishing sector may affect both the ecological sustainability of the fishery and the ability of local fishing associations to effectively govern fisheries. Results show that although the fishery sector is not undergoing a rapid modernization, loss in traditional practices, beliefs, and values are occurring and may be linked to corresponding declines in marine resources. Improved monitoring systems will help inform local governing institutions about the need to develop enhanced management practices. The second paper examines the effectiveness of community-based governance of artisanal fisheries and addresses the overarching goal of the study by improving understanding of the key elements of success of the community fishing associations. These fishing associations collectively design, monitor, and enforce local regulations. Decisions are based on local knowledge and experience, and management strategies are based on low-cost, practical solutions. Compliance with local regulations is high, primarily due to participatory decision-making, community-monitoring, and strong feelings of solidarity among fishers. The last paper looks at fisherwomen on Ngazidja and focuses specifically on documenting their fishing practices, livelihood contributions, and potential participation in fisheries management. This paper is critical to enhancing understanding of the impacts and potential of the fishery on Ngazidja as the sector has so far failed to take into account all marine harvesting activities, particularly those undertaken by women. Moreover, authorities have recently attempted to ban women from fishing as their practices are considered destructive to near-shore reefs and juvenile fish populations. Results from the study indicate that women’s fishing methods can be destructive and may have contributed to localized declines in intertidal marine resources and habitats. Yet, fisherwomen also provide substantial contributions to household livelihoods. Thus, banning the fishery altogether is not an acceptable solution. Instead, authorities should work to empower fisherwomen with the tools necessary to manage their fishery sustainably, which will eventually lead to improved conservation measures. Overall, this case-study provides a unique example of how collective governance of common-pool resources can be achieved within communities, and how feelings of empowerment and shared responsibility among users can lead to effective management practices. There are a number of clear lessons learned from the successes of this fishery that can be applied to other similar small-scale fisheries. Future research priorities should concentrate on assessing the ecological sustainability of current fishing and management practices, and paying particular attention to the recognition and inclusion of fisherwomen. Marine conservation and sustainable fisheries systems are only facilitated when all users are recognized and engaged in management and policy decisions. / Graduate

Determinants of Maternal Perceptions of Child Health in the Informal Urban Settlement of Kibera in Nairobi, Kenya: a Quantitative Study

Drengson, Jane 06 September 2013 (has links)
As populations in informal urban settlements continue to grow, an increasing number of people are exposed to unsafe living conditions. Children are particularly vulnerable to the environmental risks associated with this settlement type. While much is known about child morbidity and mortality in informal urban settlements, little is known about maternal perceptions of child health. This thesis explores the determinants of maternal perceptions of child health in the informal urban settlement of Kibera in Nairobi, Kenya. Data utilized in this thesis come from A Kenya Free of AIDS (KeFA), a research-based, National Institute of Health-funded project. Through Respondent Driven Sampling (RDS), 320 women in Kibera were recruited for interviews. Of these, 277 reported having children in their care and were accordingly selected for analysis. Questions selected for analysis were divided into four categories: child health, maternal background, social and economic support, child characteristics and maternal health. Data were analysed using Student’s t-tests, chi-squares, and multiple regression methodology. Two different response variables were used in the regressions: general child illness rating and infrequency of child illness. Analysis indicated that women in the sample were significantly more likely to report poor child health if they: had more children in their care, had younger children in their care, were involved in an intimate relationship, and had experienced a recent barrier to medical treatment for a child. Exploring maternal perceptions of child health is critical because these perceptions are the precursor to healthcare-seeking behaviour. / Graduate / 0573 / 0766 / jdrengson@gmail.com

Power and Process: The Politics of Electricity Sector Reform in Uganda

Gore, Christopher D. 28 July 2008 (has links)
In 2007, Uganda had one of the lowest levels of access to electricity in the world. Given the influence of multilateral and bilateral agencies in Uganda; the strong international reputation and domestic influence of its President; the country’s historic achievements in public sector and economic reform; and the intimate connection between economic performance, social well-being and access to electricity, the problems with Uganda’s electricity sector have proven deeply frustrating and, indeed, puzzling. Following increased scholarly attention to the relationship between political change, policymaking, and public sector reform in sub-Saharan Africa and the developing world generally, this thesis examines the multilevel politics of Uganda’s electricity sector reform process. This study contends that explanations for Uganda’s electricity sector reform problems generally, and hydroelectric dam construction efforts specifically, must move beyond technical and financial factors. Problems in this sector have also been the result of a model of reform (promoted by the World Bank) that failed adequately to account for the character of political change. Indeed, the model of reform that was promoted and implemented was risky and it was deeply antagonistic to domestic and international civil society organizations. In addition, it was presented as a linear, technical, apolitical exercise. Finally the model was inconsistent with key principles the Bank itself, and public policy literature generally, suggest are needed for success. Based on this analysis, the thesis contends that policymaking and reform must be understood as deeply political processes, which not only define access to services, but also participation in, and exclusion from, national debates. Future approaches to reform and policymaking must anticipate the complex, multilevel, non-linear character of ‘second-generation’ policy issues like electricity, and the political and institutional capacity needed to increase the potential for success. At the heart of this approach is a need to carefully consider how the character of state-society relations in the country – “governance” – will influence reform processes and outcomes.

The pragmatic markers anyway, okay and shame : a comparative study of two African varieties of English

Fairhurst, Melanie 12 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: The goal of this study was to determine and compare the functions of the pragmatic markers (PMs) okay, anyway and shame as they occur in two spoken components of the International Corpus of English (ICE), namely ICE-SA (South African English) and ICE-EA (East African English). Using the commercially available Concordance program WordSmith Tools 4.0, all instances of okay, anyway and shame were identified in each corpus and all non-PM instances were then excluded. The remaining instances of okay, anyway and shame were subsequently hand coded to determine the primary functions that these elements exhibit. The classification of the various functions was done according to Fraser’s (1996, 1999, 2006) framework for identification of PMs. Despite the different size and state of completion of the two corpora, it was found that the functions of the two PMs okay and anyway were similar in South African English and East African English. The findings of the corpus investigation included identifying the functions of okay as both a conversational management marker and a basic marker, as well as its role in turn taking. Anyway was found to function as an interjection, a mitigation marker, a conversational management marker and a discourse marker. Shame was found to be a uniquely South African English PM, and to function both as an interjection and as a solidarity marker. / AFRIKAANSE OPSOMMING: Die doel van hierdie studie was om vas te stel watter funksies verrig word deur die pragmatiese merkers (PM's) okay, anyway en shame, soos wat hulle gebruik word in twee gesproke komponente van die Internasionale Korpus van Engels (IKE), naamlik IKE-SA (Suid-Afrikaanse Engels) en IKE-OA (Oos-Afrika Engels). Met behulp van die kommersieel-beskikbare Concordance-program Wordsmith Tools 4.0, is alle gevalle van okay, anyway en shame binne die onderskeie korpusse geïdentifiseer, waarna alle nie-PM gevalle uitgesluit is. Die oorblywende gevalle van okay, anyway en shame is daarna met die hand gekodeer ten einde die primêre funksies van hierdie elemente vas te stel. Die funksies is geklassifiseer volgens Fraser (1996, 1999, 2006) se raamwerk vir die identifikasie van PM's. Ten spyte van verskille in die grootte en vlak van voltooidheid van die twee korpora, is vasgestel dat die PM's okay en anyway soortgelyke funksies verrig in beide Suid-Afrikaanse Engels en Oos-Afrika Engels. Uit die korpus-analise het dit verder geblyk dat okay nie net 'n rol speel in beurtneming nie, maar ook funksioneer as 'n gespreksbestuur-merker en basiese merker. Anyway blyk op sy beurt te funksioneeer as 'n tussenwerpsel, versagting-merker, gespreksbestuurmerker en diskoersmerker. Laastens is gevind dat shame as PM uniek is aan Suid- Afrikaanse Engels en dat dit funksioneer as beide 'n tussenwerpsel en solidariteitsmerker.

Access to essential medicines in East Africa: A review of East Africa community and its member states approach to WTO-TRIPS public health flexibilities

Majok, Daniel Bol January 2018 (has links)
When the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) was annexed to the Agreement Establishing the World Trade Organisation (WTO) in 1994, it set minimum standards for intellectual property (IP) protection, including protection of patent rights, that must be observed and enforced by all WTO Member States. On the one hand, stringent Intellectual Property protection as seen innovation in the field of science where medical innovation hasled to the creation of live saving vaccines which have reduced prevalence of diseases, ranging from polio to the human Papillomavirus, and invention of antiretroviral medicines which have greatly improved the lives of people living with the Huma Immunodeficiency Virus (HIV). On the other hand, the fulfilment of the obligations under TRIPS has generated a lot of controversy especially as they have been seen as the cause of reduced access to essential medicines in developing countries. / Magister Legum - LLM (Mercantile and Labour Law)

Religion, Colonialism, Diaspora: The Role of the Hindu Swaminarayan Sect in Indian Migration to Africa and the World

January 2016 (has links)
abstract: A new sect of Swaminarayan Hinduism emerged in the late eightieth century. This sect rapidly grew into a global organization due their highly structuralized nature. Fascinatingly, the new sect was able to create the feeling of home away from home in multiple countries. Through the establishments of mandirs, Hindu place of worship, practitioners were able to solidify the feeling of home away from home. Through books, magazine articles and letters the evidence of the new sect creating this feeling is overwhelming. Diaspora theory is woven within the thesis due to the global nature of the sect. This thesis uses a broad definition of diaspora to encompass the change in literature due to the ability of one to maintain close ties to their old homeland. The Swaminarayan sect treaded through diaspora by assimilating to their new homeland all the while keeping a close tie with their old homeland. / Dissertation/Thesis / Masters Thesis Religious Studies 2016

Ecological Sanitation in Uganda: Promotion through Demonstration Facilities and Potential for <i>Ascaris</i> Reduction by Free Ammonia Inactivation Using Stored Urine

Trimmer, John Thomas 01 January 2015 (has links)
As Uganda works to transform itself into an industrialized, middle-income country in the coming decades, the country is faced with a number of problematic trends that could hinder this transition. High population growth and urbanization are quickly forcing small towns to deal with issues of limited space and the aesthetic conditions within sanitation systems, while declining soil fertility in surrounding rural areas calls into question the future nutritional security of the growing population. Ecological Sanitation (Eco-San) systems, which are designed to recover nutrients from human excreta, may help to address these trends. Improved sanitation coverage in Uganda is currently estimated to be 34%, with most people using either improved or unimproved pit latrines. Eco-San systems, especially Urine-Diverting Dry Toilets (UDDTs, also referred to as composting toilets), have been promoted in the country, but uptake has been slow. Additionally, while UDDTs generally treat human feces to a greater degree than pit latrines and composting toilets (another type of Eco-San system), concerns have been raised as to the inactivation of environmentally persistent pathogens, such as Ascaris lumbricoides eggs. This research focused on two potential solutions to the issues of effective promotion and Ascaris inactivation, evaluating them in the context of Kalisizo, a small town in southern Uganda. Demonstration facilities have been reported to effectively convince local stakeholders of the benefits and advantages of UDDTs, thereby increasing long-term uptake of the technology in the surrounding community. However, an unresolved question concerns whether these facilities should be installed in household or institutional settings. The initial effects of demonstration facilities constructed at local primary schools in Kalisizo were evaluated by assessing local knowledge and attitudes regarding UDDTs, both before installation and after several months of operation, through focus group discussions and key informant interviews. In general, this promotion strategy proved to be successful. After installation, students exhibited a marked increase in knowledge regarding these facilities and their benefits, and opinions were strongly positive. These changes were seen in users of the facilities as well as non-users, and students expressed clear acceptance of using the products of the toilets to fertilize crops. The introduction of an improved sanitation system at the schools also appears to have sparked other improvements related to sanitation and hygiene. In the future, it is likely that students will be compelling representatives for UDDTs within their households and communities. Regarding the treatment of persistent pathogens, previous work has demonstrated that the elevation of free ammonia levels to levels that can inactivate Ascaris eggs can be achieved through the urea addition. In this research, use of stored urine as an ammonia source for treatment of fecal products from UDDTs in Uganda was investigated. Mixtures of stored urine, fecal products from UDDTs, and wood ash were prepared, and treatment conditions (pH, temperature, ammonia concentration) were compared to the results of previous Ascaris inactivation studies to determine whether this strategy would be a feasible and effective treatment alternative. Results indicated that a volumetric mixture containing two parts stored urine and one part fecal products could provide 4-log1¬0 inactivation of Ascaris eggs after five months of indoor storage or after three months of outdoor storage. This strategy could improve the safety of recovered products while maintaining their agricultural value. Social acceptance of the treatment system appears to be possible with proper education efforts, and a cost comparison showed that this system may be more economically favorable than typical double-vault UDDTs.

Zeolite Facies and Environmental Change in the Plio-Pleistocene Baringo Basin, Kenya Rift

Minkara, Karim 18 December 2017 (has links)
Sediments exposed in the Tugen Hills in the Central Rift of Kenya include an important hominin-bearing succession of volcaniclastic and fluvio-lacustrine deposits. The Hominin Sites and Paleolakes Drilling Project (HSPDP) retrieved a ~230 m core through a portion of the Chemeron Formation, containing a highly resolved succession of strata spanning events leading to the Plio-Pleistocene boundary (3.4-2.6 Ma). Trends in the character and abundance of zeolites indicate changes in paleoenvironmental conditions with varying stability identified through distinct facies assemblages. These seem to reflect high amplitude changes accompanying peak earth-orbital eccentricity at ~2.7 Ma, and relative stability at low eccentricity at ~2.9-2.7 Ma. This study suggests a decrease in K/Ca and an increase in Na/Ca with major fluctuations. Zeolites act as terrestrial climate proxies in the absence of biogenic material, aside from intervals of diatom-rich strata, and are suggesting episodes of strongest environmental fluctuations ~2.7-2.6 Ma and environmental stability ~2.9-2.7 Ma.
