  • Description: This study reports on the direct use value of secondary resources harvested by rural communities in a savanna region of South Africa. Data pertaining to the use, amount and direct use value of 11 secondary resources were presented individually, along with a final composite value. Only five resources (fuelwood, construction wood, edible fruits, edible herbs, and medicinal plants), individually accounted for more than 10% of the total value per hectare (US$ 141), and together they represented over 94% of the total value per hectare. On a per household basis, only 3 of the 11 resources contributed 10% or more to the total direct use value (US$ 386 used at home and US$ 767 traded), and together contributed greater than 71% of the total direct use value per household. Two-thirds of the value per household was traded locally with other households or regionally, rather than consumed at home. The total value per hectare compared favourably with other land uses within the region, except for capital intensive enterprises. The returns to collecting and selling secondary resources were higher than those paid for local agricultural wage labour. The extraction rates of several of the secondary resources are probably sustainable but not for the more important ones such as fuelwood, construction wood and medicinal plants.

  • Description: Despite the massive contribution women make around the world, they still fall into the category of the poorest and the most oppressed. Women have borne the brunt of the social costs of the changes in the world economy such as globalisation, increased international competition, structural adjustment and the deregulation of labour legislation. Massive technological advances have done little to benefit women around the world. In fact, in many instances it has actually increased their hardships. Multinational companies search the globe for areas that offer cheap labour and poor working conditions. Globally, women make up the bulk of the army of so-called “flexible”, cheap workers sought after by employers anxious to increase their profits. It is women who are mostly to be found in sweatshops and who are least likely to be organised. In South Africa, there is already a significant trend of homeworking in the clothing sector and casualisation in the retail and other sectors. And when they are organised into unions, women struggle to be recognised as leaders in those movements.

  • Description: This thesis examines distributed authentication in the process of controlling computing resources. We investigate user sign-on and two of the main authentication technologies that can be used to control a resource through authentication and providing additional security services. The problems with the existing sign-on scenario are that users have too much credential information to manage and are prompted for this information too often. Single Sign-On (SSO) is a viable solution to this problem if physical procedures are introduced to minimise the risks associated with its use. The Generic Security Services API (GSS-API) provides security services in a manner in- dependent of the environment in which these security services are used, encapsulating security functionality and insulating users from changes in security technology. The un- derlying security functionality is provided by GSS-API mechanisms. We developed the Secure Remote Password GSS-API Mechanism (SRPGM) to provide a mechanism that has low infrastructure requirements, is password-based and does not require the use of long-term asymmetric keys. We provide implementations of the Java GSS-API bindings and the LIPKEY and SRPGM GSS-API mechanisms. The Secure Authentication and Security Layer (SASL) provides security to connection- based Internet protocols. After finding deficiencies in existing SASL mechanisms we de- veloped the Secure Remote Password SASL mechanism (SRP-SASL) that provides strong password-based authentication and countermeasures against known attacks, while still be- ing simple and easy to implement. We provide implementations of the Java SASL binding and several SASL mechanisms, including SRP-SASL.

  • Description: The end of the Cold War and the collapse of the Soviet Union has encouraged democratisation in most parts of Africa. At the same time, Western donors' attitudes towards r~cipients of foreign aid have changed. This has resulted in a new practice, which attempts to force Third World states to move toward liberal democracy by conditioning lending on the holding of mUlti-party elections. In Africa this has resulted to the holding of multi-party elections. This study attempts to examine donor conditionalities and democratisation in Kenya by examining the results of 1992 and 1997 multi-party elections. Kenya attained independence from the British and ushered in a multi-party democracy in 1963. Since then, the country has undergone a full circle of political development, starting with a multi-party democracy at independence, through a one party dictatorship between 1982 and 1992 and back to a multi-party democracy in 1993. The need to satisfy foreign donors forced the leadership to amend Section 2(A) of Kenya' s constitution that had legalised single-party rule in 1982 thus allowing plural politics. The externally pressured transition to multi-party democracy though has resulted in increased corruption, state-sponsored ethnic violence, continued political authoritarianism and disastrous economic mismanagement of what was once considered a model for the continent. This study urges that Western donors should focus less on elections and more on the fostering of democratic institutions through breaking patterns of neo-patrimonial rule that have inforn1ed and continue to inform politics in Kenya. Political reforms have been resisted by the incumbency in the fear tha! they may curtail the power of the political leadership whose main objective has been to cling to power.

  • Identifier: vital:10806 , http://hdl.handle.net/10948/25 , Wind pumps
  • Description: The lack of services such as electricity in the rural areas of South Africa has given rise to the use of pump water and the windmills. The ones in use currently are maintenance intensive. There is a corrosive element in water and this sometimes requires plastic or other non-corrosive materials to be used for pump components and pipes. Solar panels are expensive and have low efficiencies. Alternative energy systems such as diesel engine driven- mono pumps or -turbines or windmills are costly, which means that the overall efficiency must be maximized to reduce these costs.

  • Description: The dependency of educators in Lesotho on externally developed curriculum theories and concepts is fundamental to issues of relevance of the school curricula. This study set out to develop the meaning of environmental literacy in the context of three secondary schools and to explore appropriate teaching methods for the development of this concept in the science curriculum. The participatory action research process involved a team of four science teachers, including the researcher, in partnership with an environmental centre. We progressively developed the meamng of environmental literacy by monitoring teaching innovations in the classroom, holding meetings and workshops and attending conferences where we shared classroom findings and reflected on our emerging understandings based on classroom experiences. Data collection involved: audio-recording of classroom lessons, interviews with teachers and students, audio-visual recording, classroom observations and students' questionnaires. The research process made apparent the complex nature of the process of clarifying and developing environmental literacy in this context. Classroom actiyities planned to inform the team's understanding of the meaning of environmental literacy and develop appropriate teaching methods encountered constraints associated with the education system and the legacy of colonialism. These contextual constraints crystallised the need for the education system to be transformed in order to make schools more conducive environments for the gevelopment of students' environmental literacy. While initially teachers were reluctant to engage in critical reflection, the research process did encourage the team to revise and expand their understandings of both environmental literacy in the science classroom, and the action research itself. The emerging meaning of environmental literacy in this context and how it may be developed among students does not involve a definition with prescriptive, effective teaching methods, but provides insights and understandings gained by the participants in their engagement with a reflective process of reconslructing meaning. I have come to understand environmental literacy during the study to be a process that should draw strongly on the local knowledge and understandings into the science curriculum, through participatory process-based curriculum development models.

  • Description: Estuarine biogeographical regions along the southeastern coast of South Africa were investigated in terms of fish distribution and abundance patterns, with particular emphasis on the role of water temperature in influencing these patterns. Qualitative and quantitative analyses were conducted upon the ichthyofaunal assemblages to determine whether the location of the subtropical/warm temperate boundary corresponds to that proposed by Whitfield.(n1) Analyses included the distribution ranges of species associated with estuaries according to presence/absence data, cluster analysis of gill net catches in eight estuaries along the southeastern coast and the relative proportion of tropical to temperate marine species within these eight systems. Quantitative analysis indicated that the ichthyofaunal biogeographical regions are indeed a reflection of water temperature regimes and that the subtropical/warm temperate boundary is located between the Great Kei and Mbashe estuaries. A strong negative correlation was found between the number of temperate fish species and the mean of the minimum monthly temperatures recorded in the systems studied. Qualitative analysis revealed that a barrier appears to exist in the vicinity of the Swartkops estuary, which prevents the westward migration of tropical 'vagrants'. The influence of the Agulhas Current along the east coast and its divergence from the coastline in the Algoa Bay region, as well as upwelling phenomena on the southeast and south coasts are identified as major factors that influence marine and estuarine temperature regimes and therefore the ichythyofauna of this region.
