Abstract:

A systematic drilling and optical dating programme on Middle Kalahari beach ridge (relict shoreline) sediments has enabled the identification of multiple episodes of lake high stands of an extensive palaeolake system at the terminus of the Okavango Delta, northern Botswana. This paper presents 23 ages from the Mababe Depression and establishes four shoreline construction phases in the late Quaternary coeval with other sub-basin lake high stands (Lake Ngami). These synchronous lake phases result from a coalescence of the sub-basins into a unified palaeolake, Lake Thamalakane, covering an area of ∼ 32,000 km2. Six additional ages are also presented from the Chobe enclave to the north of the basin where shoreline ridges were emplaced at the same time as Lake Thamalakane phases. This suggests that increased flow in the Chobe and Zambezi system significantly contributed to the Middle Kalahari lake phases in both the post-glacial and Holocene periods. The integration of these new data and their compatibility with other regional and tropical palaeo-archives is discussed in the light of understanding Quaternary climate drivers within the Kalahari.

Abstract:

AbstractDiatoms and sediments were examined in a 530 cm core from Ishiba Ngandu, Zambia, a lake formed by gentle downwarping. Diatom zone D (>20 cal ka BP) was mostly sand with abundantAulacoseiraandEunotia, suggesting a shallow lake perhaps kept fresh by spring inputs and lake discharge, except during deposition of the lowermost 66 cm. Gyttja deposition between about 22 and 20 cal ka BP suggested a deeper lake and a wetter climate, perhaps because the Congo Air Boundary (CAB) was farther southeast relative to modern times. The next zone, zone C (about 20–19 cal ka BP), was sand with abundantAchnanthidiumandEunotiabut very few planktonic diatoms, apparently representing very shallow water and an arid period without the CAB. The gyttja and diatoms in zone B (19–4 ka) suggested an increase in moisture when the CAB returned. Zone A (4–0 cal ka BP) was dominated by the planktonicAulacoseira(>89%), suggesting an increase in wind-driven mixing. Uniquely, Ishiba Ngandu likely has been relatively moist since the last glacial maximum, matching pre-Holocene wetness in Botswana but not its Holocene aridity; evidently the climate here had switched to that of East Africa.

Abstract:

Women have always played a large part in the visual arts throughout Africa. In Botswana at the present time this is illustrated most immediately by the woven baskets, seen everywhere, in galleries, shops and at roadside stalls, that have come to represent the country and its arts and crafts; and with the odd exception they are all made by women in the most rural areas. However, women in Botswana currently practice other arts, including house decoration and pottery, although, for a variety of reasons, these are less immediately obvious. In contrast to these practices, representing traditions inherited from the past, there are others of relatively recent inception. Since the 1980s Botswana has seen the emergence of a small number of women ‘Fine’ artists, some of whom are Botswana nationals while others are expatriates settled in the country. In contrast to arts made for immediate local use, or sold in roadside stalls, the work of these artists is exhibited in the few art galleries that now exist. During the same period, art education has also been gradually introduced into the school and university system in Botswana. Art galleries both private and public are another recent development, beginning with the National Museums and Monuments Art Gallery, which opened in 1978, and which began to facilitate local exhibitions of Botswana art, while also encouraging exhibitions of this material in other countries. In addition to local tradition and an emerging Fine Art practice, art education, museums and galleries, a series of workshops has also been developed. Some of these were set up by expatriates on a more-or-less permanent basis with the aim of training women in various art forms, while others are temporary and artist-led, giving selected groups of artists the chance to meet, work and exchange ideas. I begin this thesis, therefore, with a survey of all the arts inherited from the past, and currently practised by women in Botswana, and then, in a series of chapters I look at each of the developments, including art education, museums and galleries, and workshops; and their histories, their aims, and their achievements with particular regard to the overall development of the arts in Botswana. This thesis thereby provides a comprehensive study of all the arts practised by women in Botswana through the last thirty years.

Abstract:

A travers l'analyse de matériel macrobotanique (charbon et graines / fruits) issus de trois sites majeurs du Later Stone Age (LSA) d'Afrique australe, cette étude s'intéresse à reconstituer les conditions environnementales durant l'Holocène dans la région, en particulier au cours des deux à trois derniers millénaires. L'étude de ce matériel, accompagné de la constitution d'une collection moderne de références de la végétation du bassin Kgalagadi, vise à mieux cerner l'impact quel'environnement a pu avoir sur les sociétés humaines (subsistance, peuplements, etc.) à une période-clé du (LSA), qui marque l'émergence des pratiques pastorales dans la région. L'étude des environnements est ici primordiale pour interpréter les conditions qui ont pu favoriser l'arrivée de ces premiers éleveurs et leurs lieux d'installation. En complément, une approche ethnographique a été menée, en travaillant avec les communautés locales dans la région de l'Erongo en Namibie, qui peuvent aider à comprendre et reconstituer les pratiques passées d'utilisation de la végétation
Through macrobotanical (wood charcoal and seeds / fruit) analysis from three major Later Stone Age (LSA) sites located in the Kgalagadi Basin in southern Africa, this study is interested in reconstructing the environmental conditions during the Holocene in the region, in particular in the last two to three millennia. Initially this work couples archaeological macrobotanical analysis with the construction of modern reference material in an effort to trace the environmental / vegetal evolution as well as to comprehend socio-ecological and socio-environmental dynamics in Southern Africa during the late Holocene. The scope of this study covers the period spanning the last 3000-2000 years, with the main objective of understanding what relationships humans had with their environment at a time linked with the arrival or the appearance of the first herding practices in that part of Africa. These herding practices are believed to be accompanied by significant human movement from eastern or central Africa southwards. Favourable environmental conditions may have influenced their routes as well as settlement choices, and these are aspects that this archaeobotanical study aims to address. This study also employed an ethnographic approach, working with local communities in the Erongo region of Namibia, so as to make inferences to past vegetation utilisation practices while at the same time discerning and reconstituting past human activities

Abstract:

This chapter is a case study analysis of the management of the Adult Basic Education Program in Botswana. The chapter focuses on management issues in the ABEP program using two districts as a case study. The case study examined management issues faced by those implementing the program. The findings reveal that while the program has undergone several comprehensive structural changes, the reality on the ground has remained the same and worsened in some areas. The program faces a problem of lack of resources such as office accommodation, office furniture, and transport to effectively run the activities of the program. The lack of transport leads to poor supervision, late payment of facilitators and at times to cancellation of planned program activities. Responses were consistent in the two districts to suggest there are some wide ranging issues that probably affect all parts of the program.

Abstract:

Despite its role and relevance in environmental management at all scales the use of fire has been contentious. The absence of information on fire parameters compounds the situation. This study derives fire parameter information for Botswana by analyzing MODIS fire data for (2001-2012), using conditional statements, and cluster mapping in ArcGIS. The study also related the fire information to other variables to examine how they interact with fire. The results of the study indicates that over the 12 year period the burned area has exhibited an upward trend. It has also shown that most of the fire in the country occur over the late dry season when the fires are potentially destructive. A south-north transect of fire frequency is observed, accompanied by an inverse relationship between frequency and intensity. Of all the factors, rainfall (0.638) and biomass(NDVI) (0.355) were the most significant contributors to the fire activity. The study demonstrated the utility of the MODIS fire data in characterizing the fire regime of the country and thus contribute to the policy process.

Abstract:

This study aims to examine the impact of ethics in the knowledge management in organizational development in Botswana. Importance of ethics in knowledge management is growing at a faster pace of late; still some employees tend to be unethical. As organization consists of different people with different ethical cultures, it is essential that organizations should make their employees follow ethical principles while creating, sharing and using both explicit and tacit knowledge to have optimum organizational development. Respecting ethics by human resources helps to improve implementation of knowledge management. The chapter main focus is on Management of ethics in an organization which influences knowledge management processes and subsequently influence organizations development. To locate ethics impact on knowledge management for organizational development, the scholars employed a survey strategy where respondents indicated that there is a significant impact of ethics in knowledge management for organizational development.
