DR Congo has experienced more than two decades of conflict and profound political upheaval, sparking humanitarian crises which have seen large-scale relief efforts to alleviate them. Aid workers and UN staff working there have been caught up in the violence, sometimes with deadly results and major disruption to aid operations. Nonetheless there has been a tendency to assume that most security incidents involving aid workers are a result either of pure criminality, or because the victims happened to be in the wrong place at the wrong time. Is that really the case however, or are humanitarian workers perceived as political actors, and thus vulnerable to politically motivated violence? This dissertation conducts an empirical data study of attacks against humanitarian actors, UN workers and peacekeepers between 2006-2018, mapping them against political developments. Following previous work by Hoelscher, Mikllian & Nygard, this research tests what impact the nature of the conflict or the change of peacekeeping mandate has on both aid-worker and UN personnel security, as well as exploring the different risks faced by national and international staff working for international NGOs. It also, using an interpretivist lens first proposed by Labonte & Edgerton, explores the role of the Congolese state in aid-worker security, testing whether relations between the host government and aid providers can impact individual aid-worker security on the ground. The results indicate that both conflict intensity and elections cycles could impact on rates of attacks against aid-workers, as well as clearly demonstrating that national staff are far more exposed to risk of attack, and that fatalities of UN staff since the peacekeeping mission (MONUSCO) in DRC received its more aggressive mandate in 2013 have risen sharply. The research also raises questions about the potential threat posed by the Congolese state to aid-worker security, given the nature of statehood in DRC, its motives and perceptions of aid operations, and the state’s role as both the main belligerent and security provider in zones where humanitarian workers chiefly operate.

Four species were selected within the littoral of Tshegera Island, and include H. astatodon, H. olivaceus, H. crebridens and H. paucidens. These species, identified on basis of the SMRS, express their individuality most strongly with respect to dentition, breeding colours, normal habitat and preferred breeding territory. All four species are maternal mouthbrooders. This reproductive strategy is characterized by complete division of labour and polygamy. Breeding males compete for optimal territories and ready to spawn females. They are characterized by fast growth, large size and overall low condition factor. Females invest in few but large yolked ova and go through a fasting period while incubating the eggs. Females are generally characterized by slower growth, smaller size and higher condition factor when compared to males. In females the energy turnover during gonadal development and subsequent mouthbrooding is high, but the energy expenditure low. Mean fecundity varies between 25 and 36 eggs per brood and mean egg size between 2.6 and 2.7 rnrn. The right ovary, although small, is functional. Breeding of variable intensity goes on throughout the year. The main dry season corresponds to synchronized breeding. During the other months of the year species breed asynchronously. Both types of breeding are related to food availability for adults and offspring. The major breeding peak which starts in July coincides to improved body condition in both sexes. In similarity with the East African flocks, the Lake Kivu haplochromines display subdivision within the major trophic groups and invasion of the major lacustrine habitats. They are nevertheless morphologically and ecologically generalized. They tend to be plesiomorphic with low diversification within each trophic group, have a lake wide distribution (eurytopic) and incline to be altricial within their specialized reproductive guild. The evolutionary status of the Lake Kivu haplochromines may be explained by survival of members of an ancestral fauna in an isolated bay during the Recent volcanic events which destroyed life in the Main Basin. The Lake Kivu flock, therefore, is a relict and is believed not to have evolved within the confines of the present-day lake.

This dissertation is a contextual reading of 1 Samuel 25:14-35 that highlights the Abigail approach to peacemaking. The synchronic analysis of this text done in the light of the context of North Kivu conflict resolution focuses on the literary analysis of the text. The interaction between the two contexts of peacemaking, in the Abigail narrative and the North Kivu context, allows me to recommend "participative negotiations" as a suitable diplomatic means to solve North Kivu conflicts for a lasting peace. In fact, participative negotiations inspired by the Abigail strategy contrast with the diplomacy of avoidance and competitive negotiations, by which North Kivu cannot reach lasting peace. However, the strategists of peacemaking, involving North Kivu rank-and-file in the peacemaking process, must first build mutual confidence between the parties in conflict during discussions, then analyse their respective interests, and bring them to suggest suitable strategies using objective criteria which can lead the parties to true consensus. / Old Testament & Ancient Near Eastern Studies / M.

The city of Bukavu, located at the eastern border of the Democratic Republic of Congo in the province of South Kivu, is a large and densely populated urban agglomeration that has experienced rapid growth during recent years. At the same time, Bukavu has been repeatedly struck by environmental hazards, especially by devastating landslides. The steepness of slopes in the city’s hilly and mountainous terrain is one of the most important factors contributing to landslide susceptibility, but the anthropogenic impact resulting from uncoordinated urban sprawl and land cover change additionally plays a crucial role in exacerbating the vulnerability of neighbourhoods. This thesis utilizes GIS software to provide cartographic material for landslide risk assessment in Bukavu and the city’s surroundings. It examines risk exposure related to slope inclination of densely built-up areas, the spatial development of the city and urban growth tendencies, and complements these aspects with information about land cover and the terrain.

M. Tech. (Department of Information and Communication Technology, Faculty of Applied and Computer Sciences), Vaal University of Technology. / In most African countries, agriculture remains a key factor in economic development with over half the population living in rural areas and directly or indirectly deriving their livelihoods from agriculture. Agriculture still faces several challenges that prevent it from being able to make its maximum contribution to economic expansion, despite it being the backbone for economic growth. As a major cause for change in all spheres of human lives, information and communications technology (ICT) has played a positive role in different segments of society, such as agriculture, education and community development. However, it could play a greater role in agriculture by assisting farmers who face challenges on a daily basis. Farmers may lack an operative way to gather farm produce data, to obtain information from other interested parties (e.g. agriculture advisers) and to record farm input expenses and expenditure on farm chemicals. These and other challenges experienced by farmers may be solved by gaining ICT access through using available technologies. Farmers need to benefit from earlier unexploited opportunities regarding the provision of cost-effective communication and learn about advanced practices previously unknown to them. In this research study, the researcher studied factors that influence farmers in the adoption of a mobile crowdsourcing portal for agriculture purposes. A model was used to measure the perception of farmers about the technology after having used it for a season. The model consisted of the following variables: quality factors; perceived ease of use; experience; perceived usefulness; attitude toward using; and behavioural intention to use. A test for reliability and validity proved that the model was acceptable. The results of the data analysis indicated that there was a strong relationship between the multiple independent factors and the dependent variable in the model. The researcher concluded that mobile crowdsourcing applications are perceived as enhancing agricultural development in remote areas with regard to data accessibility, the development of crop production, support in the decision-making process and their importance in sustaining agricultural activities.

With a volcanic origin, Lake Kivu is deep and meromictic, and shows a very particular limnology and some astonishing features. The data available on its limnology and phytoplanktic communities are limited, dispersed or outdated. This is the first deep, long term study (2002-2004) on limnology and phytoplankton ecology of Lake Kivu, combining different techniques: HPLC analysis of marker pigments, flow cytometry, light, epifluorescence and electron microscopy. Lake Kivu combines a relatively shallow euphotic layer (~18m) usually smaller than its mixed layer (20 – 60 m), and with a weak thermal gradient in the mixolimnion. With an annual average chlorophyll a in the mixed layer of 2.2 mg m-3 and low nutrient levels in the euphotic zone, the lake is clearly oligotrophic. Concerning its phytoplanktonic composition, the most common species were the pennate diatoms Nitzschia bacata Hust. and Fragilaria danica (Kütz.) Lange Bert., and the cyanobacteria Planktolyngbya limnetica (Lemm.) Komárková-Legnerová and Cronberg and Synechococcus sp. Diatoms were the dominant group in the lake, particularly during the dry season episodes of deep mixing. During the rainy season, the stratified water column, with high light and lower nutrient availability, favoured dominance of cyanobacteria. Phycoerythrin-rich phototrophic picoplankton and heterotrophic bacteria cell numbers were constantly high, with relatively subtle spatial, seasonal and vertical variations. In open lake waters, where allochthonous carbon inputs are most probably inconsequential, HNA heterotrophic bacteria abundance is strongly correlated with chlorophyll a. Recent investigations revealed an increasing methane production in the deep waters during the past three decades, leading to an accumulation of gas and the subsequent lowering of the energy required to trigger a devastating release of gasses. The role of primary producers and the probable changes on the export ratio of the organic matter into deep waters after the introduction of the planktivorous sardine from Lake Tanganyika Limnothrissa miodon, is discussed. The actual primary production, 0.71 g C m-2 d-1 (~ 260 g C m-2 y-1), doesn’t seem substantially different from some punctual measurements made in the past, which discards the hypothesis of anthropogenic eutrophication. We believe that the export ratio of organic matter into the deep waters was largely affected by biological changes that could explain part of the methane increase in the past 30 years in Lake Kivu.
