Analysis of the impact of training and capacity building by CASP on raising the income levels of emerging farmers in Limpopo Province

Xaba, Sharon Thembi 12 1900 (has links)
Thesis (MDF)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The South African government continues to provide post-settlement support to emerging farmers, with the objective of improving productivity through targeted funding or conditional grants. The Comprehensive Agricultural Support Programme (CASP), which came into effect in 2004, provides funding targeted at supporting emerging farmers. CASP has six pillars, of which this study focused on one, which is capacity building and training. The study investigated the assessment of the impact of training on the projects’ beneficiaries who had benefited from the CASP pillar of training and capacity building in the Limpopo Province. The methodology applied was the difference-in-difference technique. Projects that benefited from funding were regarded as the treatment group and those that did not benefit from the programme were regarded as the control group. The justification for the research was that while the government had financed CASP through fiscal allocation since 2004, because CASP is a conditional grant, there was a need to review the programme, focusing on establishing whether the budget allocation had achieved its intended objectives during this time. The objectives of the study were to measure whether there had been an improvement in the beneficiaries’ income levels. It focused on the status of the projects prior to the beneficiaries receiving training and benefiting from capacity building, and what the status was after receiving training through the programme, with the key determinant being an increase in income levels. Not all funded projects had benefited from the particular pillar investigated here. The selection of the beneficiaries to be trained was based on a skills audit which treated the groups as homogeneous, which was found to be inappropriate because of the differences in the prior skills, education levels and the specific interests of individuals. The findings were that there was variation in the increase of income levels. There was a positive relationship between training and reported increase in income levels in some projects, and a negative relationship between training and income levels for other projects. It was interesting that income levels increased for projects that had benefited from the CASP pillar of training and capacity building when the projects were analysed as a group, but when projects were analysed individually, it was revealed that there was a marginal decrease in income levels. There should be a shift in policy. The focus on training and capacity building should be a priority and should occur prior to the projects receiving infrastructure support. The 10% of the total CASP budget allocated for training and capacity building needs to be reviewed, taking into account that low skills levels continue to be the main reason why projects are not sustainable. There is also a need to review the impact of training. The type of training offered should not be generic for all projects, it should be differentiated to suit the both the people and the commodities concerned and should be more biased towards entrepreneurship, as this would enable emerging farmers to grow their business units and realise increased income levels.

Nitrogen management strategies on perennial ryegrass-white clover pastures in the Western Cape Province

Labuschagne, Johan 03 1900 (has links)
Thesis (PhD(Agric) (Agronomy))--University of Stellenbosch, 2005. / The response of perennial ryegrass and white clover, grown under controlled conditions, to fertiliser N rates applied under variable soil temperature (6, 12 and 18 °C), soil water potential (-10, -20, -25 and -35 kPa) and seasonal growing (June/July and October/November) conditions as well as field conditions, were evaluated. Primary- (PDM), residual- (RDM) and total dry matter (TDM) production (g pot-1) were recorded over the first- and second regrowth cycles as well as the accumulative DM production over the two regrowth cycles, respectively. Leaf N content (%) was recorded at the end of first and second regrowth cycles. Tiller/stolon numbers and root dry mass (g pot-1) were recorded at the end of the second regrowth cycle. Soil ammonium-N and nitrate-N (mg kg-1) content was monitored after fertiliser N application. Decreasing soil temperatures resulted in decreased TDM production in both crops. Only perennial ryegrass was influenced by fertiliser N rate, with a general increase in dry matter production as fertiliser N rate was increased. Ryegrass TDM production did not differ between the 100 and 150 kg N ha-1 rates but were both higher (P=0.05) if compared to the 0 and 50 kg N ha-1 treatments. Soil nitrate levels 31 days after application of 150 kg N ha–1 were still sufficient to stimulate ryegrass RDM production. The 173.8% increase in ryegrass TDM production measured at 6 °C where 150 kg N ha-1 was applied compared to the 0 kg N ha-1 treatment illustrated the ability of ryegrass to respond to fertiliser N at low soil temperatures. Soil water potential of -20 kPa resulted in higher ryegrass PDM and TDM production compared to the -25 and -35 kPa levels. White clover PDM and TDM production were however not influenced by soil water potential or fertiliser N rate. Ryegrass TDM production increased (P=0.05) as fertiliser N rates were increased. The most favourable soil water level for both ryegrass and clover root development was found to be -35 kPa. Perennial ryegrass and white clover PDM, RDM and TDM production were higher during the October/November season compared to the June/July season. Increased fertiliser N rates resulted in increased (P=0.05) ryegrass PDM and TDM production. White clover dry matter production was not influenced by fertiliser N rates. In the field study the effect of 0, 50, 100 and 150 kg N ha-1 applied as a single application either in autumn, early winter, late winter, early spring or late spring on pasture dry matter production, clover content and selected quality parameters of a perennial ryegrass-white clover pasture were investigated. Soil nitrogen dynamics in the 0-100, 200-300 and 400-500 mm soil layers were studied for 49 days following fertiliser N application. The effect of 50 kg N ha-1 on soil N dynamics was generally the same as found at the 0 kg N ha-1 applications and may therefore be regarded as a low risk treatment. The application of 150 kg N ha-1 especially in autumn and early winter showed a tendency to exceed the absorption capacity of the pasture and thereby expose fertiliser N to possible leaching and contamination of natural resources. Increased fertiliser N rate resulted in a general increase in pasture dry matter production with the highest yields recorded where N was applied in early and late spring and the lowest in early winter. The application of 150 kg N ha-1 in early and late spring resulted in the highest TDM production, however, the 50 kg N ha-1 resulted in a more efficient conversion of N applied to additional DM produced. In contrast to DM production, the clover percentage generally decreased as fertiliser N rate was increased. The effect of season of application was inconsistent. Annual trends show that the clover percentage eventually recovered to the same levels as the 0 kg N ha-1 treatments. Due to the above minimum levels recorded for most mineral and quality parameters tested it is envisaged that treatment combinations as used in this study will not be at any disadvantage to pasture and animal productivity. The study has shown that the use of fertiliser N to boost perennial ryegrass-white clover productivity and thereby minimising the negative effect of the winter gap on fodder flow management during the cool season in the Western Cape Province, may be an important management tool. Except for late spring applications, all seasons of application reduced the negative impact of the winter gap on fodder availability. It is concluded that regression lines as summarised in Tables 7.2 and 8.2 show great potential to be instrumental in developing regression models, accurately predicting the effect of fertiliser N rate on pasture performance. Other factors to be considered includes the productivity of the pasture, initial clover content, expected clover content at the end of the first regrowth cycle after fertiliser N application and the quantity of additional fodder required. Additional requirements will be to maintain and 150 kg N ha-1) in winter, as the N uptake capacity of the pasture could be exceeded and thereby increasing the risk of N leaching, resulting in environmental pollution. The N response efficiency of the pasture is also the lowest at the 150 kg N ha-1 rates, thereby reducing the profitability of these treatments.

Exploring the link between urban agriculture, food security and the role of community development: a case study of Soweto, South Africa

Molelu, Obakeng Tendani 07 May 2015 (has links)
A dissertation submitted to the Faculty of Science, School of Computational and Applied Mathematics, University of the Witwatersrand, Johannesburg, in fulfilment of requirements for the degree of Master of Science. 10 November 2014. / This MSc thesis is aimed at assessing the food security of people actively participating in urban agriculture. In addition, it aims to assess the role of community projects that are involved in urban agricultural activities in Soweto. The fieldwork took place in five suburbs of Soweto; Meadowlands, Chiawelo, Mzimhlophe, Motswaledi and Nancefield Hostel. The findings suggest that there is a link between urban agriculture and food security in Soweto. Field based research revealed that the participants who engage in urban agricultural activities are doing so to supplement their households’ daily dietary needs. The community projects that mainly engage in food gardening are doing so for the same reasons as the individuals. However there is a greater potential for the community projects to grow into more sustainable micro-economical entities that can supply the community and local retailers with locally grown cheap vegetables. Hampering this potential is the need for continuous skills development and training in agriculture and financial management. In addition, there is a problem pertaining to access to resources and funding than could assist both the community projects and individuals to grow good quality food. There is however a need for more data to assess the spatial distribution of the urban cultivators, livestock keepers and community projects. Nonetheless, it is important to note that urban agriculture is quite significant in the lives of those involved as it has helped reduce food insecurity in their households and encourages social

An urban-agricultural hub, Umngeni, Durban.

Maphumulo, Mfundo Archibald. January 2008 (has links)
Thesis (MTech. degree in Architecture: Professional)--Tshwane University of Technology, 2008. / The aim of this dissertation is to design an urban-agricultural building to facilitate small scale intensive farming on the edge of the city of Durban. The buildings assume the typology of a vertical farm which has been named the 'ZED' farm, 'ZED' being dichotomous. Firstly the term has been borrowed from Bill Dunster Architects who coined the acronym 'ZED' (Zero Energy Development), which is one of the project's inherent objectives. The second meaning of 'ZED' is a translation of the building's main programmatic function of production in the vertical Z-axis. The site is located on the interface of the metropolitan edge, in an area bustling with activity ranging from industry, trade, recreation, public transportation, and a residential component. This area is flanked by the Umgeni Road corridor and the Suncoast Casino lifestyle entertainment centre along the beachfront.

Best institutional practices for farmworker and community equity-sharing schemes in South Africa.

Knight, Sharon L. January 2003 (has links)
Farmworker equity-share schemes were initiated by the private sector in the Western Cape region of South Africa in the early 1990's as a method of redistributing farm assets to land reform beneficiaries while maintaining the viability of commercial farming operations. This study set out to identify the institutional characteristics of successful farmworker equity-share schemes in South Africa, and to discern a set of best institutional practices that will likely promote the success of future equity-share schemes. A detailed study of nine commercial farming ventures involving partnerships with farmworkers was undertaken in the Western Cape during November 2001 to explore relationships between their institutional arrangements, worker empowerment, management quality and performance. Farmworker equity-share schemes (FWES) have received both positive and negative publicity. This thesis adds to the debate surrounding these land reform projects by comparing the results of case studies conducted by the Surplus People's Project in 1998 with more recent (2001) case studies. The latter suggest that many of the concerns raised by the Surplus People's Project, such as beneficiaries' participation and expectations, power relations between management and worker-shareholders, skills transfer and labour relations, have been addressed. The dissertation also highlights those issues that remain areas of concern, for example, beneficiaries' tenure security, literacy levels amongst worker shareholders, skill and wage differences between men and women, and exit procedures. A cluster analysis of variables measuring four constructs of a successful farmworker equity-share scheme, viz. sound institutional arrangements, effective worker empowerment, competent management and good performance, revealed positive relationships between these constructs. Best institutional practices identified by the analysis suggest that farmworker equity-share schemes should be operated as (or like) a company with voting and benefit rights proportional to individual shareholdings, but with restrictions on certain share transactions to prevent free-riding by non-workers and the loss of creditworthiness through sudden outflows of equity and managerial expertise. However, this positive relationship between best institutional practices and enterprise performance is dependent on effective worker empowerment (e.g. skills transfer and gender representation), good governance (e.g. external auditing) and competent management (e.g. schemes to reward worker performance and to resolve disputes). From a policy perspective it is recommended that public land reform grants should be awarded only to beneficiaries of FWES that have been co-financed by a bank or reputable investor as this ensures a thorough financial assessment of the project, and only to projects that can demonstrate a history of good labour relations. It is also recommended that the Department of Land Affairs should consider extending its grants to regular but seasonal farmworkers who wish to participate in an established project. While farmworker equity-share schemes may not provide all of the answers to land reform they have an important role to play in redistributing wealth and de-racialising commercial agriculture in South Africa. / Thesis (M.Agric.Mgt.)-University of Natal, Pietermaritzburg, 2003.

Weidingsbestuur in 'n semi-ariede omgewing met GIS : Paulshoek gevallestudie

Combrink, A. P. (Adrian Peter) January 2004 (has links)
Thesis (MSc)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: Grazing management in the semi-arid communal areas of Namaqualand is investigated in this study. Paulshoek, situated in the Leliefontein Communal Reserve area, is delineated as the study area and consists of 20 OOOha.Cattle farming is practised by most households primarily on a subsistence basis. It is also used as a source of income when financial problems arise. The management of grazing-land in terms of formal rules and regulations is non-existent with only mutual relationships between farmers. The aim of this study is to develop a spatial framework for the management of a sustainable grazing regime with the aid of Geographic Information Systems (GIS) technology. This aim is reached through three overlapping goals which are researched individually. The goals are to create a spatial image of the physical resource base as well as resource usage and from this the development of a computerised (Excel spreadsheet) spatial management framework for sustainable grazing management. Through the use of existing data available from the National Botanical Institute (NB!) as well as other sources and with the aid of GIS technology, coupled with Indigenous Knowledge, these goals were reached. The stockpost as individual entity is studied to give a broader understanding of how the herdsmen see their immediate environment. The grazing management system, as presented in this thesis, consists of a simple Excel Spreadsheet, with inputs from GIS technology and Indigenous Knowledge. The area is overgrazed, as is seen in the widespread occurrence of kraalbos cross the Paulshoek landscape. The recommendations are that this management system should be implemented, which could minimize the futher overgrazing of the area. The management system relies heavily on the cooperation of the community and the integration of existing management systems and policies. It will give a more detailed account of who may own how many stock and where they may graze in the communal rangelands which will also help in the establishment of new permanent waterpoints in the area. / AFRIKAANSE OPSOMMING: Weidingsbestuur in die semi-ariede gemeenskaplike gebiede van Namakwaland is in hierdie studie ondersoek. Paulshoek, geleë in die Leliefontein Gemeenskapsreservaat gebied, word as studiegebied afgebaken en beslaan ongeveer 20 OOOha.Veeboerdery word deur meeste van die huishoudings primêr as bestaansboerdery beoefen. Dit word ook gebruik as 'n bron van inkomste wanneer finansiële probleme ondervind word. Die bestuur van weivelde in terme van formele reëls en regulasies is glad nie ter sprake nie, slegs onderlinge verhoudinge tussen veeboere bestaan. Die doel van hierdie studie is om 'n ruimtelike raamwerk te ontwikkel vir die bestuur van 'n volhoubare weidingsregime deur die aanwending van Geografiese Inligting Stelsels (GIS). Hierdie doel word behaal deur drie oorkoepelende doelwitte wat elk afsondelik behandel word. Die doelwitte is om 'n ruimtelike beeld van die fisiese hulpbronbasis asook die benuttingsregime van die hulpbron te skep, en hieruit 'n rekenaar-gesteunde (Excel sigblad) ruimtelike bestuursraamwerk vir volhoubare weidingsbestuur te ontwerp. Deur gebruik te maak van bestaande inligting afkomstig vanaf Nasional Botaniese Instituut (NBI) asook ander bronne en met die koppeling van GIStegnologie en Inheemse Kennis (IK) is die doelwitte bereik. Die veepos word as entiteit behandel om 'n beter verstandhouding op te bou van hoe die veewagter sy onmiddelike omgewing bestuur. Die weidingsbestuurstelsel, soos voorgestel in hierdie tesis, bestaan uit 'n eenvoudige Excel sigblad, gekoppel aan GIS-tegnologie en Inheemse Kennis. Die gebied is oorbeweid, soos gesien kan word aan die verspreiding van kraalbos regoor die landskap van Paulshoek. Die aanbevelings is dat die bestuurstelsel geïmplementeer moet word om te verhoed dat die gebied verder onderhewig sal wees aan intensiewe beweiding. Die bestuurstelsel berus op die samewerking van die gemeenskap en die integrasie van bestaande bestuurstelsels. Dit sal tot gevolg hê 'n meer volledige opname van wie hoeveel vee mag besit en wie waar mag vestig in die weiveld gebied, wat gevolglik ook die skepping van nuwe permanente waterbronne sal vergemaklik.

Landbou en sy biofisiese omgewing : 'n GIS gebaseerde analise van die volhoubaarheid van landboupraktyke in die Piketbergse landdrosdistrik

Opperman, Daleen 03 1900 (has links)
Thesis (MA)--Stellenbosch University, 2001. / ENGLISH ABSTRACT: Agriculture occupies 86 percent of land that is being utilised for the needs of a growing population in the Western Cape. This implies that there has to be certain impacts on the environment regarding the practices associated with different agricultural activities. Negative impacts pertain to soil degradation, water quality problems, loss of biodiversity and vegetation deterioration. It must also be taken into consideration that each land use within agriculture has a different interaction with the environment. The nature of land use and environment will therefore determine the most important issues influencing the extent of impact on the environment. Certain problem areas in the Western Cape have been identified as the result of conflict between agriculture and the environment. However, if agriculture is practiced and managed in a sustainable manner, it can be productive, while at the same time assuring a healthy environment. To achieve such a situation a protocol has to exist whereby sensitive areas, with regard to potential impact on the environment by agriculture, can be identified. Considering this, the most important concept of the study was to develop methodology appropriate for evaluating and identifying farming areas where current practices threaten the sustainable use of natural resources. The result is a model that aims to identify the different land uses and then evaluate each agricultural activity through a holistic approach with regard to impact on the environment. The Piketberg magisterial district was chosen as study region to put the methodology into practice. Datasets regarding soil types, climate, water quality, vegetation and agricultural practices, specific to the study area, were gathered. By using Geographical Information Systems, the datasets could be manipulated to derive the necessary information needed for running the model. This produced maps showing areas of low to high impact on the environment and indicating the specific landuse responsible for each impact. / AFRIKAANSE OPSOMMING: Landbou beslaan 86 persent van die grond in die Wes-Kaap wat aangewend word om te voorsien in die behoeftes van 'n groeiende bevolking. Praktyke verbonde aan die onderskeie landbouaktiwiteite het egter sekere impakte op die omgewing. Negatiewe impak hou verband met gronddegradasie, waterkwaliteitprobleme, verlies aan biodiversiteit en plantegroei agteruitgang. Elke landbougrondgebruik het ook 'n spesifieke interaksie met die omgewing. Die belangrikste bydraende faktore tot impak op die omgewing sal dus deur die aard van die grondgebruik en omgewingsensitiwiteit bepaal word. Sekere probleemareas is reeds in die Wes-Kaap geïdentifiseer weens negatiewe interaksie tussen landbou en die omgewing. Indien landbou egter volhoubaar beoefen en bestuur word, kan dit produktief wees en terselfdertyd 'n gesonde omgewing verseker. Die behoefte het ontstaan om 'n protokol binne landbou te vestig, waardeur daar gefokus word op die uitwysing van risikoareas met betrekking tot degradasie van omgewingskwaliteit as gevolg van landbouaktiwiteite. Alles inaggenome, was die belangrikste doel van die studie om 'n metodiek te ontwikkel vir die evaluering en identifisering van boerderygebiede waarin die volhoubare benutting van die natuurlike hulpbronne bedreig word deur huidige produksiepraktyke. Die resultaat was 'n model wat landboupraktyke deur 'n holistiese benadering ten opsigte van die impak op die omgewing evalueer. Vir toepassing van die metodologie is die Piketbergse landdrosdistrik as studiearea geïdentifiseer. Verskeie datastelle, onder andere klimaat, grondtipes, waterkwaliteit, plantegroei en landboupraktyke, spesifiek aan hierdie area is verkry. Deur Geografiese Inligtingstelsels is die datastelle gemanipuleer en die toepaslike inligting afgelei vir gebruik in die model. Die eindresultaat was verskeie kaarte waarop die potensiële impak van landbou op die omgewing van hoog na laag geklassifiseer is. Spesifieke landboupraktyke verantwoordelik vir die impak, hetsy hoog of laag word ook aangedui.

The agricultural development of the 1820 settlement down to 1846

Webb, Arthur (Arthur C M) January 1975 (has links)
Preface: The arrival of the 1820 Settlers in South Africa and their impact on the political and social life of the Cape Colony has been well covered by historical research. This work is an attempt to illuminate yet another area in which their impact was felt. The failure of the settlement scheme under which these people were introduced into the colony has tended to detract from the importance which agriculture played in the early years of their residence in South Africa. The failure of the first crops may well have ended the attempts by many to establish themselves on the land but for others it was the beginning of a process of adaptation to the agricultural conditions of a new country. In this they were remarkably successful and within a decade the English farming community of the eastern frontier was prospering. The theme of this work traces the progress of these farmers through the initial period of crop failures, which condemned the settlement in the eyes of many, and through the ensuing years and later misfortune, the Sixth Frontier war of 1834-35. Both these setbacks were very significant in moulding the development of agriculture as practised by these farmers. In the past, historians have tended to over-estimate the reverse suffered by these farmers during this frontier war. The seemingly paradoxical questions raised by the rapid recovery of this community after the war have been left largely unanswered. Some attempt is made in the pages which follow to shed new light on this issue. In the first three chapters of this work the letters written by Thomas Philipps to his family in Britain form the chief source of information. Much of this correspondence has already found wider publication in a volume edited by Arthur Keppel-Jones, but there are significant omissions, particularly with regard to Philipps' commentary on agricultural matters. Unfortunately, this series of letters ends in 1830, and the chief sources for the latter period of this work are the various entries made) on agricultural matters, in the Graham's Town Journal, together with the farm diary of James Collett, another frontier farmer. From these, and various other works, it has been possible to trace the major developments of this farming community.
