Most research on southern Africa focuses on the total dependency of the region's states--Angola, Botswana, Lesotho, Malawi, Mozambique, Swaziland, zambia and Zimbabwe--upon the dominant power, South Africa. This thesis examines the relationship between South Africa and Zimbabwe and argues that these two states are more interdependent than dependency scholars would acknowledge. Although a study of the historical period reveals that dependency theory, as defined by Raul Prebisch, Andre Gunder Frank and A. Valenzuela, is helpful for understanding the development of relations between the two states, it is unable to account for many of the characteristics of the relationship which are found in the contemporary context, especially since 1980. An examination of various economic areas of interaction, including investment, trade and transportation, as well as the political realm, indicates that each state exhibits a degree of dependence upon the other. Thus, it is possible to characterize the relationship as one of "mutual dependence," or interdependence as defined by Robert Keohane and Joseph S. Nye. Interdependence is further examined through the concepts of sensitivity and vulnerability. Sensitivity signifies the ability of a state to respond effectively to policy changes made by another state wi thin a given area of interaction without incurring large costs, while vulnerability denotes that an actor is unable to respond, or only at great cost. By applying these concepts to the relationship between Zimbabwe and South Africa, it is determined that although South Africa tends to be sensitive while Zimbabwe is generally vulnerable, the degrees to which these two states are sensi ti ve and vulnerable varies over time and issue area. As the changes wi thin South Africa start to affect relations wi th the rest of southern Africa, it wi 11 be necessary to understand the interaction between the states from an interdependency perspective if cooperation within the region wi 11 be successful. By appl ying an interdependence framework, this study aims at contributing to the understanding of relations among the countries of southern Africa in general, and between South Africa and Zimbabwe in particular.

This study was particularly aimed at the examinations and the effect they have on schooling at the secondary school level in Zimbabwe. The views and opinions of teachers on the use of terminal examinations for certification and the influence they are seen to have on teachers' approach to the curriculum were examined. The literature has shown that there is widespread criticism of the justice and effects of terminal examinations. It is argued that they lead to an over-emphasis of that which is measured, knowledge and intellectual ability, at the expense of that kind of education progress which is almost impossible to measure in an end-of-the-course assessment. Three hundred and six secondary school teachers responded to a survey which asked for teachers' perceptions of examinations and the curriculum. The findings of this study indicated that teaching is structured towards examinations. Although teachers are trying to teach and develop reasoning skills and other activities, the pressure of examinations and the importance of doing well in them force teachers to restrict themselves to examination requirements.

Cette thèse propose une ethnographie des devenirs des fermiers blancs saisis sur le long terme de leur présence au Zimbabwe. L’analyse est centrée autour d’un moment de crise, les occupations de fermes en cours, qualifié dans ce travail d’éthique et de critique. Ces occupations s’attaquent symboliquement et réellement aux restes de la colonisation au Zimbabwe. Leur étude nous a conduits à nous interroger sur les manières suivant lesquelles la décolonisation est mise en oeuvre dans le Zimbabwe du Président Mugabe et sur les enjeux qui concernent la forme, notamment sur le plan légale, de la postcolonie. Ces occupations ont provoqué l’expulsion de plus de 90 % des fermiers blancs hors de leur lieu utopique, à savoir la ferme, et les ont poussés dans des espaces d’ambiguïté à l’intérieur desquels les occupants cherchent la confrontation. La question de la corruption (économique et morale) est au coeur de l’expérience des fermiers blancs qui ont été forcés de renoncer à leur intégrité. Certains d’entre eux ont tenté par divers moyens de la maintenir en se préservant de la corruption et en réclamant le respect de leurs « droits »; d’autres ont accepté de vivre dans la zone grise que constitue l’occupation de leur ferme. Cette thèse qui s’ancre dans l’anthropologie postcoloniale est organisée en trois parties. La question centrale de la première partie qui est d’orientation historique interroge la forme que les settlers ont donnée à ce pays et la manière mise de l’avant par les fermiers blancs pour faire de ces terres africaines « leur » lieu. Dans la deuxième partie, l’instauration après 2000 du Fast-track land reform programme et l'expérience quotidienne des occupations du point de vue des fermiers blancs sont analysées dans le détail. Dans la troisième partie, la vie des fermiers dépossédés de leur ferme est abordée à partir d’Harare, la capitale du Zimbabwe et de la Grande-Bretagne où ils ont trouvé refuge. Ceux qui vivent actuellement à Harare se sont réorganisés socialement et économiquement en redéfinissant les limites, notamment morales, de la communauté. Ceux qui, fuyant le Zimbabwe, sont « retournés » en Angleterre sont redevenus des Anglais.

Larga historia de segregación racial desde el siglo XIX en el que los colonizadores blancos llegaron a estas tierras. El racismo invadió todos los campos, en todas partes. En los años veinte y treinta los blancos pensaban que los negros eran inferiores a nivel intelectual y que sólo servían para realizar tareas manuales y repetitivas. Al mismo tiempo que el apartheid, se acentuaba entre las razas, la polarización entre grupos opuestos iba incrementándose. Por ello, no es de extrañar que la garantía de la educación en estos países ha sido siempre enormemente desigual, debido a la política basada en la segregación que es estableció durante los años previos a la independencia. Pero a pesar de la recién adquirida independencia y el advenimiento del gobierno de la mayoría queda mucho por hacer en ambos países, a nivel educativo para conseguir la igualdad de oportunidades, no solo entre los distintos grupos raciales, sino también entre los distintos niveles de estratificación social. Ambos países están realizando esfuerzos por modificar las desigualdades históricas en la financiación de la educación, apuntando a la consecución de sociedades más equitativas, pero diversos factores como los económicos, continúan determinando el ritmo al cual se desarrolla la eliminación de las desigualdades, al igual que la raza, la religión y la clase social.

This article is about the politics of conservation in postcolonial Southern Africa. It focuses on the process and consequences of redefining the Nile crocodile as an endangered species and explores the linked local and international, commercial and conservationist interests that allowed the animal to re-establish itself in state-protected waterways in colonial and postcolonial contexts. It investigates the effects of the animal's successful re-accommodation by examining conflicts between crocodiles and the fishing communities sharing space on Lake Kariba, Zimbabwe. Fishermen's hostile representations of the animal emphasize competition for fish, harassment, fear, loss of assets and loss of life. Their fear of crocodiles is heightened by the animal's entanglement in local social life, through its association with witchcraft. The article emphasizes the importance of considering both hegemonic and marginalized ideas about animals in the light of the material interactions, relations of power and historical contexts that shape them. Understanding the attitudes and circumstances of the local communities who bear the physical and economic costs of living with dangerous animals is important-it threatens the future of conservation programmes and reveals the potential for significant abuses to accompany the conservation of wildlife in postcolonial contexts. © 2004 Elsevier Ltd.

Indehiscent fruits of six tree species, common in Matabeleland were examined in in vitro and in vivo trials. The results for two of them, Acacia nilotica and Dichrostachys cinerea are presented here. Acacia nilotica-contained more total phenolics than D. cinerea, but less nitrogen (N) and fibre (ADF and NDF). After 48 h incubation, in vitro OMD of both species was increased by PEG and NaOH or wood ash treatment, except when NaOH or wood ash were used in combination with PEG with D. cinerea fruits. DM intake, DMD were lowest and N-retention negative in goats fed A. nilotica as supplement. However when fed a supplement of D. cinerea, untreated or treated with PEG or NaOH, digestibility and N-retention were highest, and similar to a commercial goat meal, with the untreated fruit. In a trial in which milking does were supplemented with D. cinerea fruits, for 65 before and 65 days after kidding, kid birthweight and weaning weight were increased by supplementation. Deaths of twin-born kids were lowest in the supplemented but unmilked group. Supplementation with D. cinerea fruit resulted in improved goat performance. The only treatment applied of practical significance, wood ash, is currently being tested in an in vivo study. More research is required on detoxification of tannins, especially with A. nilotica.
