Abstract:
The iconic African baobab tree (Adansonia digitata) has “chiropterophilous” flowers that are adapted for pollination by fruit bats. Although bat pollination of baobabs has been documented in east and west Africa, it has not been confirmed in southern Africa where it has been suggested that hawk moths (Nephele comma) may also be involved in baobab pollination. We used a citizen science approach to monitor baobab tree and flower visitors from dusk till midnight at 23 individual baobab trees over 27 nights during the flowering seasons (November–December) of 2016 and 2017 in northern South Africa and southern Zimbabwe (about 1650 visitors). Insect visitors frequently visited baobab flowers, including hawk moths, but, with one exception in southeastern Zimbabwe, no fruit bats visited flowers. Citizen science enabled us to substantiate preliminary conclusions about the relative importance of moth versus bat pollination of baobabs in southern Africa, with important implications for resource management.

Abstract:
Changes in land use type (LUT) are a major driver of biodiversity loss and species decline. Responses to changes in LUT are species-specific, which may in turn be context-dependent. Understanding such responses is essential for the management of socio-economically important wild tree species. The baobab, Adansonia digitata L., is an important traditional agroforestry tree species in Sub-Saharan Africa. This study assesses how LUT affects the demographic and spatial structure of baobab stands. Using data from a census and mapping of baobab trees in 12 plots of 250 m × 250 m each, the study compared baobab tree density, total height and diameter, diameter size-class distribution (SCD), stand stability, and spatial relationships in a strictly protected area (national park), a buffer zone and farmlands (Matéri and Boukombé) in the Pendjari Biosphere Reserve in Benin. The results show that the highest young and adult tree densities are in farmlands (particularly in Matéri), followed by the buffer zone and the national park. No significant differences in tree diameter and total height of baobab trees were found among the different LUT. The SCD had a reverse J-shape with a better negative slope and population stability metrics in farmlands (particularly in Matéri) but a flattened slope in the buffer zone. The spatial distributions of juvenile and adult baobab trees were random, and independent of each other. The spatial distribution of juvenile and adult baobabs was also independent of the other tree species, irrespective of LUT. It was concluded that baobab conservation is better in farmlands than in the national park but that the difference between park and farmlands may be context-dependent, probably linked to local environmental conditions, the socio-ecological context and interactions with baobab trees.

Trees are known to live for many years. Gautama Buddha attained enlightenment while meditating underneath a peepal tree (Ficus religiosa). A branch of the original tree was rooted in Anuradhapura, Sri Lanka in 288 B.C. and is known as Jaya Sri Maha Bodhi. It is the oldest plant in the world. Long-living plants are found in many parts of the world. The Baobab tree is one among them. Baobab is the common name of a genus of trees (Adansonia) distributed in Madagascar, Africa, Australia and India. The Baobab is the national tree of Madagascar. The Baobab is also known as “bottle tree”, “the tree of life”, “upside-down tree”, and “monkey bread tree”.

Abstract:
SUMMARYPhotosynthesis and biomass production by millet (Pennisetum glaucum) and taro (Colocasia esculenta) grown under baobab (Adansonia digitata) and néré (Parkia biglobosa) was studied at Nobéré (Burkina Faso) with the aim of optimising parkland systems productivity. Millet yielded the highest biomass under Baobab and the lowest biomass was recorded in the zone close to the tree trunk of néré. In contrast, the biomass of taro was higher in heavy shaded zones under néré and the zone close to baobab's trunk. The two crops showed an increasing trend of photosynthesis rate (PN) from tree trunk to the open area. However, the increase in thePNof taro from tree trunk to the open field was lower compared to that of millet. By increasing its leaf area index (LAI) under shade, taro displayed higher biomass production under tree compared to the open area while an opposite trend was observed in millet. The high millet biomass production under baobab could be explained by light availability and the reduction of temperature under shade compared to the open field. The adaptation of taro to shade by increasing its LAI and thus avoiding drastic reduction inPNunder shade resulted in better biomass production under heavy shade. Therefore, it was concluded that by replacing millet with taro under dense tree crowns the productivity of agroforestry parkland systems could be increased.

Abstract:
The baobab tree (Adansonia digitata L.) is an important source of non-timber forest products in sub-Saharan Africa. Its fruits contain high amounts of vitamin C, calcium, and dietary fibre. In addition, other parts of the tree are traditionally used for human consumption, particularly during lean seasons. In line with the increasing demand for natural, healthy, and nutritious food products, the baobab has great potential to contribute to human nutrition and rural livelihoods. In Malawi, where demand for baobab has substantially increased within the last decade, baobab fruits are being processed into a variety of food and non-food products, such as fruit juice, ice-lollies, sweets, and cosmetics. Yet, information on the sociodemographic background and quality preferences of baobab consumers is scanty. The current study, therefore, aimed to (1) map the diversity of baobab products available in Malawi; (2) determine consumer segments and their preferences for the most common baobab food products; and (3) examine the contribution of major attributes of processed baobab food products on their price. We employed a mixed-methods approach including the analysis of 132 baobab products and a survey of 141 consumers in formal and informal retail outlets, adopting multistage and purposive sampling. Qualitative and quantitative data were analysed using cluster analysis, cross tabulation, and hedonic regression. Results pointed to two distinct consumer segments for baobab food products, largely following the formal–informal product divide currently existing in Malawi. Both segments clearly differed with regard to preferred product attributes. We also showed that extrinsic product attributes such as packaging quality, labelling, conformity with food standards, or health claims provided distinct differentiation potential for baobab food manufacturers. In addition to providing empirical evidence for the transition of baobab food products into higher-value market segments, our results can help food processing enterprises to improve the composition and marketing of their baobab products.

Abstract:
Baobab ( Adansonia digitata L.) is an iconic tree of African savannahs. Its multipurpose character and nutritional composition of fruits and leaves offer high economic and social potential for local communities. There is an urgent need to characterize the genetic diversity of the Kenyan baobab populations in order to facilitate further conservation and domestication programmes. This study aims at documenting the genetic diversity and structure of baobab populations in southeastern Kenya. Leaf or bark samples were collected from 189 baobab trees in seven populations distributed in two geographical groups, i.e. four inland and three coastal populations. Nine microsatellite loci were used to assess genetic diversity. Overall, genetic diversity of the species was high and similarly distributed over the populations. Bayesian clustering and principal coordinate analysis congruently divided the populations into two distinct clusters, suggesting significant differences between inland and coastal populations. The genetic differentiation between coastal and inland populations suggests a limited possibility of gene flow between these populations. Further conservation and domestications studies should take into consideration thegeographical origin of trees and more attention should be paid to morphological characterization of fruits and leaves of the coastal and inland populations to understand the causes and the impact of the differentiation.

Abstract:
The baobab tree (Adansonia digitata L.), with more than 300 uses and commercial value in EU and US, has been identified as one of the most important edible savannah trees to be conserved, domesticated and valorised in Africa. A decline in baobab populations due to overexploitation and/or changes in climate could have a significant negative effect on African livelihoods. Therefore, it is important to determine potential strategies for conservation and cultivation. The present and potential future distributions of the baobab tree were studied using Maxent niche modelling framework. And, in order to contribute to the selection of superior materials for cultivation, fruit morphology was studied in situ (in Malawi and Mali) while leaf and seedling morphology were studied in situ (in Benin and Malawi) and in a greenhouse experiment. Maxent modelling suggests that predicted changes in climate will have a negative effect on baobab tree distribution in Africa: only a percentage of the present distribution was predicted to be suitable in the future. Some countries were found not to have any suitable habitats for the baobab tree in the future. Several conservation strategies are recommended, such as in situ conservation in Protected Areas; ex situ conservation in Seed Banks and conservation through ‘sustainable utilisation’. Modelling results also showed that the baobab tree could be widely cultivated in most countries in south-eastern Africa and in the Sudano-Sahelian zone of West Africa. India, north-west Australia, Madagascar, north-east Brazil and Mexico could be other suitable places for cultivating the baobab tree outside Africa. Although results from modelling should be validated with in situ seedling experiments, there seems to be potential for the wide cultivation of this species. Significant differences in leaf, fruit and seedling morphology were observed between Benin, Mali and Malawi and also within each country. While some characteristics were correlated with environmental differences between study sites, others might be genetically determined. It seems that genetic and physiological effects play a role in baobab fruit, leaf and seedling morphology. Thus, there is room for selecting high quality baobab planting materials

Thesis (M. A. (Anthropology)) -- University of Limpopo, 2016
The baobab tree (Adansonia digitata), with more than 300 cultural and ethnobotanical uses in Africa has been identified as one of the most important savanna trees to be conserved, domesticated and valorised on the continent. A decline in baobab populations due to overexploitation could have a significant negative effect on African livelihoods. Therefore, it is important to determine potential strategies for the conservation of this tree species. The study aimed to explore the cultural significance and ethnobotanical use, as well as conservation of baobab trees by the Sagole community in the Vhembe District of the Limpopo Province, South Africa. Furthermore, the conservation efforts of this community and the provincial government were also elucidated. In the Sagole community 40 local community members, aged 20 years and older, were selected via convenience sampling. A semi-structured questionnaire was employed to collect information on the cultural significance of baobab trees to members of this community. Research questions focussed specifically on identifying folk taxonomy, the transfer of species-specific information to younger generations, and cultural taboos pertaining to the baobab. It has been discovered that young people of Sagole are not well versed in the cultural value pertaining to baobabs. Furthermore, members of the community and the village head (chief) have limited knowledge related to taboos associated with this species. Thus, when individuals transgressed a taboo related to this tree species there is no formal punishment. Sagole community members use baobab trees for various purposes such as food and medicine. The species is used medically to cure various ailments. Most inhabitants in the community harvest this tree. The most common plant parts harvested for cultural use are the fruits, bark, roots and leaves. However, community members have limited knowledge about the taboos related to harvesting of this majestic tree.

Abstract:
Tree species belonging to the genus Acacia have a significant impact ecologically and economically in southern Africa. Together with the African baobab, these trees are recognized as icons of the African landscape. They are widely distributed in this area and extensively used by local communities as sources of energy, stock feed, medical remedies and building material. There is still a substantial lack of knowledge regarding the ecological association between these plants and other living organisms such as fungi. This is, however, not new to the African continent where fungi are generally poorly studied and collected, and it is envisaged that many new fungal species will be discovered as scientists focus their efforts more on this geographical niche. An example of the lack of knowledge on the fungal biodiversity in Africa is reflected in the limited reports of members of the Botryosphaeriaceae, described to date from Acacia spp.. A review on phytopathogens in South Africa by Crous et al. (2000) indicated no records of the Botryosphaeriaceae associated with native Acacia spp. Despite the importance of many species within the Botryosphaeriaceae as pathogens, knowledge about the true diversity and taxonomy of species in this family is limited, especially where native plant communities are concerned. This dissertation attempts to contribute to knowledge on the associations between members of the Botryosphaeriaceae and indigenous Acacia trees in southern Africa, and the possible role they may play in diseases of these trees. Chapter 1 represents a literature review that focuses on fungi previously associated with Acacia spp. on the African continent. Information provided in this chapter refers to available reports on pathogens and saprophytes occurring on Acacia spp. that are both native and nonnative to Africa. Special reference is made to those occurring in southern Africa. Due to the concern of the introduction of new pathogens in areas where native and non-native plants are co-existing, emphises is also placed on the possibility of pathogen-host jumps between native and non-native Acacia spp. The potential threat they might pose to the future biosecurity of these important trees is discussed. Acacia mellifera, also known as the blackthorn, is one of the native African Acacia spp. that has been extensively studied. This tree is threatened by a serious die-back disease with symptoms similar to the die-back typically caused by members of the Botryosphaeriaceae. In an effort to understand the association of the Botryosphaeriaceae with native Acacia spp. in southern Africa, a study was undertaken to search for the presence of these fungi on especially A. mellifera in Namibia and the Pretoria area in South Africa. Other Acacia spp. were also sampled in cases where they were present in the same areas as A. mellifera. These results are presented in chapter 2. In a previous study, the fungal diversity of native trees and plant species in the Northern Cape Province of South Africa was studied. This resulted in the isolation of a number of fungi that resembled the morphological characteristics of the Botryosphaeriaceae. In chapter 3, these fungi were further identified to species level based on morphological and phylogenetic characteristics. In chapter 4 an attempt was made to compare the Botryosphaeriaceae that are associated with important native trees with those occurring on non-native trees. To accomplish this, a pilot study was done to investigate the presence of the Botryosphaeriaceae on A. mearnsii in the Gauteng Province of South Africa. Results from chapters 2 and 3 on native Acacia spp. from Namibia and South Africa served as the bases of comparison for this chapter. Results of previous studies that investigated diseases of plantation grown A. mearnsii were also included for comparison. Lastly, a summary is included to review the results of this study and also the significance and impact these results made, not only on the taxonomy of the Botryosphaeriaceae, but also understanding the fungal biodiversity of indigenous tree species in southern Africa. To date, this is the most extensive study of the Botryosphaeriaceae associated with native African Acacia spp. and it is also the first study that resulted in the describtion of so many new species in this group of fungi from a single host. Results from this study indicated that there is a significantly greater diversity in the Botryosphaeriaceae associated with native Acacia spp. in southern Africa than was previously thought. This dissertation attempts to form the basis for future studies to finally understand the interactions between the Botryosphaeriaceae and their native hosts as well as their role and threat as pathogens to indigenous and economically important plants.

Abstract:
Shea butter production in West Africa has been dominated by women and Northern Ghana specifically is a leading global producer. This thesis explores women’s perceptions of power, control and agency in the Ojoba Women’s Fair Trade Co-operative in Upper East Ghana. I add to the literature on women’s experiences with and in fair trade. I examine how the shea industry and the co-operative provide a marketplace for women and a space for women to co-operate and resist power structures. I emphasize how the Western language of empowerment builds substantially from pre-existing women’s networks and labour sharing practices in the agricultural context. The thesis evaluates the factors within Ojoba that contribute to women’s empowerment. To be ‘empowered’ in Ojoba reflects a variety of understandings, experiences and locations. Indeed “women’s empowerment” may misrepresent how the women are capable of building a physical and social space of safety, debate and growth.

Abstract:
This thesis explores the thematic desire to establish an ecological human bond with nature in four contemporary novels: The English Patient by Michael Ondaatje, The Hungry Tide by Amitav Ghosh, An Imaginary Life by David Malouf, and The Expedition to The Baobab Tree by Wilma Stockenström. These authors share a concern with the influence that language has on human perception, and one of the most significant ways they attempt to connect with the natural world is through somehow escaping, or transcending, what they perceive to be the divisive tendencies of language. They all suggest that human perception is not steered entirely by a disembodied mind, which constructs reality through linguistic and cultural lenses, but is equally influenced by physical circumstances and embodied experiences. They explore the potential of corporeal reciprocity and empathy as that which enables understanding across cultural barriers, and a sense of ecologically intertwined kinship with nature. They all struggle to reconcile their awareness of the potential danger of relating to nature exclusively through language, with a desire to speak for the natural world in literature. I have examined whether they succeed in doing so, or whether they contradict their thematic suspicion of language with their literary medium. I have prioritised a close ecocritical reading of the novels and loosely situated the authors’ approach to nature and language within the broad theoretical frameworks of radical ecology, structuralism and poststructuralism. I suggest that these novels are best analysed in the context of an ecocritical mediation between poststructuralist conceptions of nature as inaccessible cultural construct, and the naïve conception of unmediated, pre-reflective interaction with the natural world. I draw especially on the phenomenological theories of Maurice Merleau-Ponty, whose insistence that perception is always both embodied and culturally mediated truly renders culture and nature irreducible, intertwined categories. By challenging historical dualisms like mind/body and culture/nature, the selected novels suggest a more fluid and discursive understanding of the perceived conflict between language and nature, whilst problematizing the perception of language as merely a cultural artefact. Moreover, they are examples of the kind of literature that has the potential to positively influence our human conception of nature, and adapt us better to our ecological context on a planet struggling for survival.

Abstract:
The baobab tree represents a major contribution to rural communities of the south-east lowveld of Zimbabwe. The livelihood base of the study area was largely rain-fed subsistence farming whose production has declined due to frequent droughts. Harvesting of baobab tree products; leaves, fruits and bark fibre, has prospered due to poverty. These products are harvested for food, medicinal use, cash and animal harness. A mixed method approach on collection of data was employed through questionnaires, semi-structured interviews, 48-hour dietary recall and Household Food Insecurity Access Prevalence (HFIAP) template. Sixty-eight households from Wengezi and Gudyanga communities participated in this study. All the respondents from the study area indicated they were involved in using baobab products in one way or the other. According to the information collected by the HFIAP template, 76% of the households were moderate to severe food insecure. Baobab bark harvesting was common in the Gudyanga and harvesters were aware of sustainable way of harvesting it. Value-addition on baobab fruit pulp to make ice-lollies and seeds roasted to produce a coffee substitute was practised by youth projects with the help of a non-governmental organisation. Ninety-five percent of the households in the study area were in support of the idea of possible baobab tree commercial cultivation in the community. The support was in anticipation of job opportunities and reduced food insecurity.

A research report submitted to the Faculty of Science, University of the Witwatersrand, in partial fulfilment of the requirements for the Degree of Masters of Environmental Sciences by Coursework and Research Report. Johannesburg 24 March 2016
In southern Africa, the baobab (Adansonia digitata L.) is an economically important trees because it contributes significantly to the livelihoods of local people, particularly in northern Limpopo in South Africa (the southern-most edge of the baobab distribution). All parts of the baobab are useful and considered important for subsistence and commercial uses. Understanding factors that affect fruit and seed production is important to better characterize the long-term success of tree populations. Some adult baobab trees have high fruit production (50 −299 fruits per tree, per year) and are subsequently called ‘producers’ or ‘female’ trees, while there are other trees that produce fewer fruits (< 5 fruits per tree, per year) that are called ‘poor-producers’ or ‘male’ trees. For this study, baobab fruit dimensions (mass, length, volume and ratio) were, measured and compared between artificially- and naturally-pollinated producer and poor-producer trees. Fruit dimensions were also correlated to the number of seeds per fruit. Using 2D geometric morphometric analysis, baobab fruit shapes were analyzed and compared to determine if fruit shape differs between fruits formed on producer and poor-producer baobab trees. I found no significant difference in fruit shape between producer and poor-producer baobab trees. Although, artificially-pollinated trees produced bigger and more uniform shaped fruits and contained more seeds in comparison to the smaller unevenly shaped fruits produced by naturally-pollinated trees. Furthermore, I compared fruit and seed production between naturally-pollinated producer/poor-producer and between artificially-pollinated producer/poor-producer trees that occur on different land use types (i.e. nature reserves, rocky outcrops, plains, fields (land use for agricultural purposes) and villages) in Northern Venda, South Africa. There was a significant difference in fruit and seed production between naturally and artificially-pollinated producer and poor producer trees that occur on different land use types. On average, producer trees yielded more seeds than poor-producer trees. The highest fruit and seed production was recorded in fields and villages. Seed mass variation also differed significantly between producer and poor-producer trees and between the different land use types. A very weak negative relationship between baobab seed number and mass was found in both producer and poor-producer baobab trees. Baobab seed viability was estimated using a 0.1% tetrazolium solution, 100% viability was found in all tested seeds from both producer and poor-producer baobab trees. Result of this study may aid with the identification of land use types where baobabs have the lowest seed production and therefore require additional conservation effort to ensure that fruits are harvested sustainably. The estimation of seed production may improve the ability to estimate the total seed oil that is available in each land use type.
