Abstract: Major and trace element, samarium (Sm)–neodymium (Nd) and lead (Pb) isotopic analyses of individual mesobands of five Banded Iron Formations (BIFs) and associated volcanic and sedimentary rocks from the Neoarchean Tati Greenstone Belt (TGB, Northeastern Botswana) were conducted in order to characterize the source(s) and depositional environment(s). Rare earth element (REE)–yttrium (Y) patterns of individual BIF mesobands showfeatures characteristic of other Archean BIFs with LREE depletion relative to MREE and HREE, positive La/La∗PAAS, Eu/Eu∗PAAS, Y/Ho ratios and no Ce/Ce∗PAAS anomalies. The REY patterns are comparable to modern seawater and together with low concentrations of high-field strength elements these features are indicative of an essentially detritus-free precipitation. Elevated Eu anomalies in the TGB BIFs are a general feature observed in ∼2.7 Ga BIFs worldwide and possibly result from widespread magmatic activity and associated high-temperature fluid fluxes to the oceans at around this time. Uranogenic Pb isotope data for the BIFs define correlation lines with slopes corresponding to apparent ages of ∼2.7 Ga which brackets the depositional timeframe. Pb isotope data on sulfides and Pb-stepwise leaching (PbSL) data on garnets define a correlation line with an apparent age of 1976±88 Ma. This age is similar to tectono-metamorphic events within the adjacent Limpopo belt. Elevated 207Pb/204Pb relative to 206Pb/204Pb ratios of BIFs are indicative of a high- (238U/204Pb) prehistory of their source materials which can best be modeled by a 3.0–3.2 Ga extraction of these sources from an older Archean mantle reservoir. The TGB BIFs show evidence of two periodically interacting water masses during the deposition. The first is characterized by elevated Sm/Nd ratios and a negative inferred εNd(2.7 Ga) value of −2.5 and is associated with high Fe fluxes. The second source, associated with high Si fluxes, is characterized by lower Sm/Nd ratios and a less negative inferred εNd(2.7 Ga) value of −0.4. While the association of high Fe concentrations and elevated Sm–Nd in BIF mesobands is characteristic of hydrothermal seawater input, the Sm–Nd isotopic characterization of this source, unlike other Archean BIFs, points to a significantly LREE enriched mantle source. This finding is compatible with the potential existence of a sub-continental lithospheric mantle reservoir beneath the Zimbabwe and Kaapvaal craton. The old (up to ∼3.5 Ga) Nd (TDM) model ages, particularly of iron-rich mesobands of the TGB BIFs, support such a scenario. In contrast, Si-rich solutes were likely derived from weathering of mafic continental crust. URI: http://hdl.handle.net/10311/389 Files in this item: 1

Abstract: Three species of the genus Treculia namely, Treculia acuminata Baill., Treculia africana Decne ex. Treà ´cul and Treculia obovoidea N.E.Br. grow in the humid rain forest of southwest Cameroon. They are also widely distributed in tropical Africa. T. africana is commonly known as African bread fruit. These three species are commonly used in folk medicine against skin diseases and dental allergies (Berg et al., 1985). The twigs, stem and wood of T. acuminata and the leaves of T. africana, whose chemical constituents are reported herein, were collected from Kumba, Cameroon, in August 2004, and identified by Mr Victor Nana of the National Herbarium in Yaounde, Cameroon where voucher specimens (N 2921/Srf/CAM and 29053/SRF/Cam, respectively) are deposited.

Abstract: The utilization of chicken manure as an organic fertilizer is essential in improving soil productivity and crop production. We carried out the study to assess the effects of chicken manure on soil chemical properties and the response of application rate on the yield of spinach (Spinacia oleracea) as well as the uptake of nitrogen and phosphorus nutrients. To quantify these effects, we added chicken manure to samples of Calcisols, Arenosols and Luvisols at application rates: 5, 10, 20 and 40% chicken manure. The addition of chicken manure irrespective of application rate did not change the acidity or pH of Calcisol, suggesting its hypo-buffering capacity. While the results reveal increases of EC with increasing rate, at rate above 40%, the ECs were above the critical salinity level of 4 mS/cm indicating potential threat to soil productivity. The exchangeable bases increased with application rate, suggesting the positive effects of chicken manure in enhancing soil fertility. Similarly significant increase of nitrogen and phosphorus were observed following the addition of chicken manure. Initially the spinach yield increases up to optimum rate of 0.06, 0.07 and 0.16 g/plant for Luvisol, Arenosol and Calcisol, respectively and subsequently drops after critical threshold values; 15, 5 and 1% for Calcisol, Arenosol and Luvisol, respectively. Interestingly above the rate of 40%, the yield was almost zero for all soils, suggesting the ineffectiveness of chicken manure in enhancing soil productivity.

Abstract: The 1990s began with a commitment to children through the adoption, by the United Nations General Assembly, of the Convention on the Rights of the Child. This Convention set the minimum standards of protection for children's survival, health and education; protection against exploitation at work; protection against the degradations of war; and protection against physical and sexual abuse. By 20th July, 1994, 163 countries had ratified the Convention and 11 other countries had signed but not yet ratified the convention (World Health Organization, 1994:1).

Abstract: The emergence of knowledge economies and extensive use and adoption of ICT in business entities have placed more pressure on governments to implement e-Government in their public service delivery platforms. For some of the governments, implementation of e-Government follows no explicit strategy but is done with a loosely coordinated approach. A properly designed e-Government implementation strategy with input from the local context is desired if implementation were to be deemed successful. Because of efficiencies brought about by the adoption and appropriate use of ICT in businesses and other private sector entities, e-Government is slowly becoming a sine qua non for responsive and transparent governance and is seen as one of the most important ingredients to national competitiveness. Using a desk literature review, this paper emphasises the different factors that should be considered when developing e-Government projects, especially in Africa. The paper discusses the basics of e-Government readiness in Zambia by analysing the different initiatives that are being put in place to encourage e-Government development, and analyses the balance between the back-end and front-end applications in public delivery platforms. The paper posits that a lot needs to be done if proliferation of e-Government applications was to be attained in Zambia and that future Zambia and that future e-Government strategies should be implemented within the realm of community informatics. This entails the application of ICT aimed at personal, social, economic, cultural and governance development of and within communities. It is anticipated that the adoption of a community informatics approach will enable the citizens to buy-in to the different e-Government applications and thereby guarantee continued usage. This paper presents factors which may act as reference points when e-Government strategies are being drawn for the SADC region.

Abstract: In this paper we trace how Gaborone has grown from a very small village to the capital city of Botswana in a period of less than 30 years. Attention has been given to how careful design of master plan concepts has shaped the city and responded to the needs and aspirations of the residents. Through appropriate and enabling urban- development policies, standards and codes, a very amenable environment has been created. The city can boast of adequate and modern civic and commercial centers; modern functional infrastructure including water, electricity, roads and sewage systems; access to land for virtually all people; adequate housing provided by both the public and the private sectors and for the low income, the adoption of a very successful program of squatter upgrad- ing and self-help housing. Through careful management and development control practices, city growth has been contained quite well in spite of rapid development and the future of the city looks quite bright.

Code-switching in Botswana history classrooms in the decade of education for sustainable developmentMafela, L. (Routledge http://www.informaworld.com, July NaN, 2009)[more][less]
Abstract: Education is an important vehicle for the achievement of overall sustainable development. Moreover, international organisations have encouraged governments around the world to work towards achieving education for all. The notion of inclusive education has been useful in ensuring that country-level educational policies and practices incorporate and serve the interests of learners coming from diverse socio-cultural and linguistic backgrounds. Language facilitation has been earmarked by UNESCO (2005) as a necessary component of education for sustainable development. Despite global affirmation of the importance of language, the absence of language facilitation policies hampers the achievement of education for sustainable development at classroom level. This article explores language use in Botswana's History classrooms in the context of education for sustainable development. It is based on an exploratory study that was undertaken to investigate the use of code-switching in Botswana's History classrooms. The article begins with a discussion of the concept, origins and evolution of sustainable development, and how it links with education for sustainable development. The article goes on to link education for sustainable development with issues of equity and inclusiveness, and explores the role of language in the facilitation of an enabling and interactive teaching and learning environment.

Abstract: Higher education in developing countries face a particular challenge; half of the world’s higher education students are found in developing countries, placing great strain on an already under funded system. Whilst the New Partnership for Africa’s Development (NEPAD) health strategy urges countries to embark on massive capacity building, the truth is that the higher education sector in Africa does not have the resources to do so. The NEPAD higher education document (2001) proposes the idea of multi-country partnerships to address the sector’s problem and at the same time, address the capacity building needs for improved health care delivery. This paper reports on pertinent aspects of collaboration between universities on the African continent for the purpose of capacity building in nursing and midwifery. The paper outlines the rationale and context of the Collaboration in Higher Education for Nursing and Midwifery in Africa (CHENMA) project. The discussion focuses on the conditions in Africa that hamper the development of nursing and midwifery. It describes the efforts of the Tau Lambda at-Large Chapter to improve nursing and midwifery, initially in East Africa and later in Francophone Africa through the CHENMA project. The paper articulates the values and underpinning principles, outcomes of and lessons learnt from the project. URI: http://hdl.handle.net/10311/685 Files in this item: 1

Abstract: The dairy industry arose in Bechuanaland primarily as an alternative to beef production in response to South Africa's restrictions on the import of cattle from the Protectorate African dairy producers were at a disadvantage compared to settler farmers due to the lack of government support for the infrastructure essential for highly perishable dairy produce The decline of dairy production in the later colonial period can be attributed to the revival of beef exporting, which undercut the Administration's already limited interest. These events can be situated within the broader pattern of colonial underdevelopment. URI: http://hdl.handle.net/10311/699 Files in this item: 1

Abstract: The contestation for common pool resources in Botswana pits powerful institutions such as national governments and international organisations against powerless local communities who continue to rely heavily on these resources despite all attempts to dislodge them. This paper explores how common pool resource management has shifted from locally based and peoplecentred endogenous resource management to state-defined and controlled forms. This shift has marginalised San communities, who have historically relied on their commons for survival. The paper is informed by case studies of two San villages in Ngamiland District in northwestern Botswana, Mababe and Phuduhudu, both situated adjacent to national parks. The government and donor agencies introduced community-based natural resource management with the promise of reversing the loss of the commons for such groups as the San; however, the evidence on the ground suggests the promise has not been translated into practice.

Abstract: An effective response to global environmental challenges requires analysis of communication patterns, processes and approaches. In addition, improving communication through emerging information and communication technologies (ICT) also must be explored. Understanding recipients’ perception of the innovations used in information diffusion is also necessary. This study, using a sample of 120 subjects, examined attitudes of leaders of community-based natural resources organizations toward two approaches used in public instructional communication in the Okavango Delta, Botswana. The quasi-experimental study also explored the effect of demographic variables on subjects’ attitudes. The results demonstrated more favorable attitudes toward the visualized method than the traditional verbal method, suggesting subjects’ preference and acceptance for the visualized public instructional communication approaches. Results also indicated a differential effect of age on attitude toward methods of communication. The results of the study highlight the importance for practitioners to use integrated communication approaches in the public sphere. Suggestions for future research are offered.

Abstract: The Boteti River is an ephemeral outflow of the Okavango River. It lies in the north-western part of Botswana where about 25,000 people reside across a number of widely scattered villages and informal settlements. The river, with its seasonal streams and pans, is vital to the livelihoods of these people, their livestock, and the wildlife that share this physical space. A combination of factors has led to widespread degradation of the physical resource base – both in the river bed itself and in the wider environment. As part of its outreach role, the Harry Oppeheimer Okavango Research Centre has undertaken a multi-year project along the Boteti River to assist people there with the rehabilitation of their resource base. The globally influential concept of integrated water resources management (IWRM) provides the analytical framework, in particular its emphasis on dialogue and stakeholder participation. The project has three primary aspects: facilitation of a dialogue platform; action-research; outreach and information dissemination. After two years of implementation, the project has collected a good deal of data and established a River Basin Forum with a common vision. However, the project continues to face difficulties in implementation: participation is limited; myths regarding resource degradation are difficult to dispel; meaningful communication among differently empowered actors is hard to achieve; and there are numerous human, financial and technological limitations. The primary researchers continue to alter their methods in the hope of achieving a functioning River Basin Committee (RBC), but observe that the globalized ideals of IWRM are, in this particular case at least, of limited use when attempting to alter localized management practices in basins with deeply embedded social and cultural practices.

Abstract: This paper is derived from a broader study that examined community attitudes and perceptions towards ecological issues in Maun and Gaborone to determine how these could be harnessed towards ecologically sustainable urban development. The major problem in the two study sites is that there has been rapid urban growth since the 1970s, but very little attention has been devoted to the environmental implications of that growth. The environmental issues on which community attitudes and perceptions were sought included the following: urban water and waste water; urban solid waste management; urban impacts on wildlife; and urban energy conservation and management. These issues were selected on the basis of what the authors were able to obtain socio-ecological data on, given the time and financial constraints of thestudy. The urban ecosystems management model is used as an analytical framework that could be further harnessed by policy and decision-makers to mobilize stakekeholders towards sustainable urban development. A social survey method was used to generate data among heads of households in Maun and Gaborone. It was found that most ordinary members of the community were not involved by government authorities in decision-making affecting natural resource use and environmental issues. However and in general, the communities had positive attitudes and perceptions towards environmental issues. The major draw-back is that these communities are generally not consulted by state agencies in decision-making processes affecting their environment. It is concluded that this is inimical to ecological urban development. URI: http://hdl.handle.net/10311/945 Files in this item: 1

Abstract: This paper examines the impact of Community-Based Natural Resource Management (CBNRM) in Ngamiland over the past ten years. It shows that CBNRM has made some strides in strengthening and creating new organisations/ institutions, empowering local communities, creating social networks and improving the institutional capacity of community trusts. Communities receive benefits from employment opportunities, social infrastructure, provision of transport, and assistance on meeting the costs of funerals. However, the contribution of most of the benefits to livelihood diversification is limited as they mainly accrue to the communities rather than individuals. The programme faces many challenges, such as limited institutional capacity for running organizations, insecurity of tenure, stakeholder conflicts, mismanagement of funds, and problems of how to use and equitably distribute the financial benefits to individual households.

Abstract: The term empowerment has become a buzz word used by development organisations and government sectors to make development programmes sound technically correct. These programmes are often the cause of the poor becoming disillusioned and passive, since these programmes often do not achieve what they have set out to achieve. One such group that is responsible for the empowerment of community members in poverty and other special circumstances, is the home economics extension officers (HEEOs) in Botswana. This article focuses on the HEEOs’ understanding of the term empowerment as well as the subsequent actions they are taking to bring about empowerment and the hindrances that impede their empowerment practices. Qualitative data gathering methods in the form of open-ended questionnaires and semi-structured interviews were carried out with HEEOs to understand the phenomenon of empowerment. A focus group discussion was in addition conducted with one community sewing group. It became evident that HEEOs linked the term empowerment mostly to training and education. This is contrary to literature, which describes training and education as only the beginning of the empowerment process. Empowerment will however only take place if individuals are encouraged to define their own goals and to act upon them. HEEOs included community members in planning, implementation and evaluation of development programmes, but there is no evidence of authentic involvement. Community groups were also not adequately mentored and supported by HEEOs. In addition, the system within which empowerment practices are carried out appeared to be not conducive to supporting HEEOs in their empowerment practices.

Abstract: Community archaeology has conferred an alternative dimension on conventional archaeology and heritage management, empowering previously powerless peoples, particularly the indigenous and local communities that have lost rights to their heritage through colonialism. So important has its impact been that there has been only limited reference in the literature to its problems. Examination of case studies from various parts of the world reveals that problems associated with defining what a community is and who is indigenous, coupled with the existence of multiple communities with multiple interests, have sometimes diminished the utility of the approach. In some cases, archaeologists and heritage managers have been unwilling to give up some of their powers and have continued to view local communities as only passive partners. In others, local communities have considered their views and concerns more important than those of the archaeologists. As a result, the so-called equal partnerships between archaeologists and communities have disappointingly ended up as uneasy relationships. Without effective solutions to some of these problems, community archeology may remain a goal to be pursued rather than becoming standard practice.
