- Description: This study is premised on the assumption that empowering the small-scale farmers in securing property rights and enforcement of these rights are the prime movers of agricultural development. Logically, it follows that by empowering small-scale farmers and giving them access to resources such as credits, subsidies and extension services the state can play a mediating role in transforming the agricultural land scape in Lesotho. Unless farmers are empowered the water resources in Lesotho will continue to serve the interest of the rent-seeking elite. Given the nature of the issues under investigation, the mixed research methodology (the use of both qualitative and quantitative methods) was used as a method of inquiry in order to get a deeper understanding of the phenomenon of water resources management and its subsequent impact on small scale farming in the rural areas of Lesotho. Both methods played a complimentary role by capitalising on both their strengths and weaknesses so as to provide various dynamics and linkages between the two variables of water resources management and small scale farming. The material condition of small scale farmers is intrinsically associated with the active state mediation in agriculture. Yet, the adopted Integrated Water Resources Management (IWRM) approach is still to materialise. This thesis, thus, argues that there is a need for a more holistic integrated water resources management framework that is livelihoods based and re-emphasises the need for conserving the ecosystem. Therefore, implementing a more holistic integrated water resources management approach is critical and vital in improving agricultural production and subsequently the livelihoods of small scale farmers and households. Although this thesis used Lesotho as the case study, it is hoped that the findings may provide tentative answers for other Sub-Saharan countries on how to properly and efficiently manage water resources so as to boost agricultural production amongst small scale farmers in order to improve human conditions and promote sustainable development in the rural areas.

Woody plant encroachment in arid and mesic South African savanna-grasslands: same picture, different story?

- Description: Woody plant encroachment in South Africa’s savanna-grasslands has been considered a rangeland management problem since the early 1900s. This phenomenon, which has been observed globally, is particularly important in Africa given the extent of tropical grassy biomes on the continent and their importance for rural livelihoods. In this study, local and regional scale approaches were used to investigate woody cover change in South Africa across the important savanna-grassland rainfall threshold of 650 mm mean annual precipitation (MAP). The aim was to test this threshold using remote sensing and demographic surveys in order to better understand the patterns, mechanisms and drivers of encroachment. Rates of encroachment and population demographics of Vachelia karroo were compared at arid and mesic savanna sites in the Eastern Cape, using time-series analysis of historical aerial photographs in conjunction with field surveys. Changes in the extent of woodland vs. grassland were then quantified at a national scale (1990-2013) by combining optical and synthetic aperture radar remote sensing data. This produced the first map of woodland- grassland shifts for South Africa and provided the basis for a spatially explicit investigation of the key drivers of change. The local studies revealed higher rates of encroachment at mesic sites than at arid sites, with a correlation between drought and rate of encroachment at the arid site. Vachelia karroo seedlings and stunted saplings were more prevalent at mesic sites than at arid sites and the growth form of adult trees differed significantly between sites. The national remote sensing investigation showed that woodland replaced grassland in over 5% of South Africa’s savanna- grasslands between 1990 and 2014, at rates consistent with other global and regional studies. Spatially explicit models showed a pattern of incremental expansion of woodland along a ‘tree front’ and complex relationships between woodland increase and fire, rainfall, terrain ruggedness and temperature. Overall, the local and regional scale findings of this work highlight the importance of the savanna rainfall threshold (~650 mm MAP) and the presence / absence of fire in understanding savanna dynamics and woody cover change in the context of global drivers such as elevated atmospheric CO2.

“We are white”: oral tradition, documented history and molecular biology of Xhosa clans descended from non-African forebears and their expression of this ancestry through the idiom of ancestor religion

- Description: Xhosa clan membership is symbolised by a clan-name (isiduko) and passed along the male line from father to son. This social indicator has a biological counterpart in Y chromosome DNA that passes through successive generations in the patriline. Both relate specifically to a distant patrilineal forebear or apical ancestor. The present study has involved the collection and documentation of oral-historical information relating to the descent of certain Cape Nguni clans from non-African forebears and (where possible) a review of documented accounts of such origins. The research has also included collection of buccal cells from male research participants and analysis of their Y chromosome DNA. This method indicates whether a man’s patrilineal forebear lived in Africa. Otherwise, it indicates the broad geographical region from which he originated, hence providing an additional, independent source of information relating to ancestry that can confirm or challenge claims made based on oral history. Ethnographic research into the performance of distinctive ancestor rituals by clan members explores the continuing relevance of foreign ancestry in the contemporary context of rural communities in the Eastern Cape, South Africa. The study heeds calls for the decolonisation of scholarship in various ways: methodologically, through transdisciplinary research; ontologically, by questioning the utility of the nature: culture and related dichotomies; and epistemologically, because instead of relying entirely on the western academic tradition, it takes account of other modes of knowledge production. In rejection of the notion that only one side of history is true, it records multiple voices – those of the powerful but also the ordinary. The study deals with race and racial identification, but confirms the superficiality of these constructed differences by offering evidence of their submergence in the unifying power of kinship and descent.
