Into the Storm: American Covert Involvement in the Angolan Civil War, 1974-1975Butler, Shannon Rae January 2008 (has links)
Angola’s civil war in the mid-1970s has an important role to play in the ongoing debate within the diplomatic history community over how best to explain American foreign policy. As such, this dissertation uses the Angolan crisis as a case study to investigate and unravel the reasons for the American covert intervention on behalf of two pro-Western liberation movements: the National Front for the Liberation of Angola (FNLA), led by Holden Roberto, and Jonas Savimbi’s National Union for the Total Independence of Angola. That Angola is a late 20th century example of foreign intervention is not disputed. However, the more significant and difficult questions surrounding this Cold War episode, which are still debated and which directly relate to the purpose of this study, are first, “Why did the United States involve itself in Angola when it had previously ignored Portugal’s African colonies, preferring to side with its NATO partner and to maintain its distance from Angola’s national liberation movements?” Was it really, as the Ford Administration asserted, a case of the United States belatedly responding to Soviet expansionism and Kremlin-supported aggression by Agostinho Neto’s leftist Popular Movement for the Liberation of Angola (MPLA). Secondly, “Exactly when did the United States intervene, and was this intervention largely responsible for the ensuing escalation of violence and external involvement in Angola affairs?” In other words, as suggested by the House Select Committee on Intelligence, was the Soviet Union’s intervention in response to the American decision to allocate $300,000 to Holden Roberto’s National Front in January 1975? If so, then contrary to the Ford Administration’s official account of the crisis, the United States - and not the Soviet Union - was the initial provocateur in the conflict that left the resource-rich West African nation in a ruinous, perpetual state of warfare into the early 21st century.

Land Cover Change in the Okavango River Basin : Historical changes during the Angolan civil war, contributing causes and effects on water qualityAndersson, Jafet January 2006 (has links)
<p>The Okavango river flows from southern Angola, through the Kavango region of Namibia and into the Okavango Delta in Botswana. The recent peace in Angola hopefully marks the end of the intense suffering that the peoples of the river basin have endured, and the beginning of sustainable decision-making in the area. Informed decision-making however requires knowledge; and there is a need for, and a lack of knowledge regarding basin-wide land cover (LC) changes, and their causes, during the Angolan civil war in the basin. Furthermore, there is a need for, and a lack of knowledge on how expanding large-scale agriculture and urban growth along the Angola-Namibia border affects the water quality of the river.</p><p>The aim of this study was therefore to develop a remote sensing method applicable to the basin (with scant ground-truth data availability) to carry out a systematic historic study of LC changes during the Angolan civil war, to apply the method to the basin, to relate these changes to major societal trends in the region, and to analyse potential impacts of expanding large-scale agriculture and urban growth on the water quality of the river along the Angola-Namibia border.</p><p>A range of remote sensing methods to study historic LC changes in the basin were tried and evaluated against reference data collected during a field visit in Namibia in October 2005. Eventually, two methods were selected and applied to pre-processed Landsat MSS and ETM+ satellite image mosaics of 1973 and 2001 respectively: 1. a combined unsupervised classification and pattern-recognition change detection method providing quantified and geographically distributed binary LC class change trajectory information and, 2. an NDVI (Normalised Difference Vegetation Index) change detection method providing quantified and geographically distributed continuous information on degrees of change in vegetation vigour. In addition, available documents and people initiated in the basin conditions were consulted in the pursuit of discerning major societal trends that the basin had undergone during the Angolan civil war. Finally, concentrations of nutrients (total phosphorous & total nitrogen), bacteria (faecal coliforms & faecal streptococci), conductivity, total dissolved solids, dissolved oxygen, pH, temperature and Secchi depth were sampled at 11 locations upstream and downstream of large-scale agricultural facilities and an urban area during the aforementioned field visit.</p><p>The nature, extent and geographical distribution of LC changes in the study area during the Angolan civil war were determined.

However while the vigour decreased in the northwest, it increased in the northeast, and on more local scales the pattern was often more complex. With respect to migration out of Angola into Namibia, the LC changes followed expectations of more intense use in Namibia close to the border (0-5 km), but not at some distance (10-20 km), particularly east of Rundu. With respect to urbanisation, expectations of increased human impact locally were observed in e.g. Rundu, Menongue and Cuito Cuanavale. Road deterioration was also observed with Angolan urbanisation but some infrastructures appeared less damaged by the war.

Memories of the Border War: An Interpretive Analysis of White South African Defence Force Veteran Perspectives, 1966-1989Graham, Danielle 16 August 2012 (has links)
Through their stories, South African Defence Force (SADF) veterans of the Border War participate in the historical revival of South Africa’s involvement in the Angolan conflict, 1966-1989. Their engagement in the Border War discourse sets these veterans apart for an analysis of their motivations to participate and how their views compare and contrast with one another. SADF veterans are reconstructing their past within their present context in the new South Africa. Their struggle to rectify public knowledge and perceptions of the past through the provision of their personal memories is a growing trend within South Africa, one that has become a conversation between the various competing narratives.
