Academic literature on the topic 'Agricultural systems – KwaZulu-Natal – Umbumbulu'

This study investigated the impacts of cultivation on water and soil quality in the lower uMfolozi floodplain system in KwaZulu-Natal province, South Africa. We did this by assessing seasonal variations in purposefully selected water and soil properties in these two land-use systems. The observed values were statistically analysed by performing Student’s paired t-tests to determine seasonal trends in these variables. Results revealed significant seasonal differences in chloride and sodium concentrations and electrical conductivity (EC) and the sodium adsorption ratio (SAR) with cultivated sites exhibiting higher values. Most of the analyzed chemical parameters were within acceptable limits specified by the South African agricultural-water-quality (SAWQ) water quality guidelines for irrigation except for sodium adsorption ratio (SAR), chloride, sodium and EC. EC, pH and nitrate content which were higher than the specified SAWQ limits in cultivated sites. Quantities of glyphosate, ametryn and imidacloprid could not be measured because they were below detectable limits. The study concludes that most water quality parameters met SAWQ’s standards. These results argue for concerted efforts to systematically monitor water and soil quality characteristics in this environment to enhance sustainability by providing timely information for management purposes.

The use of herbicides amongst smallholder farmers is minimal because herbicides are expensive and they require specialized application equipments. Weeds are problematic in conservation agriculture where herbicides are expensive for smallholder farmers. The use of cover crops can help to suppress weed growth and development by creating an environment which is not suitable for weeds survival. Cowpea (Vigna unguiculata (L.) Walp) dolichos lablab (Lablab purpureus L.) and velvet bean (Mucuna pruriens (L.) DC) were evaluated for biomass accumulation and weed suppression under conservation agriculture system in two contrasting experimental sites: Ukulinga and Bergville in KwaZulu-Natal. Bare plot and herbicide treatments served as controls. Treatments were laid in a randomized complete block design, replicated three times. Mucuna pruriens (L.) DC had the highest biomass accumulation in both sites Bergville (0.72 t/ha) and Ukulinga (1.59 t/ha). Cowpea had the lowest biomass accumulation in Bergville (0.59 t/ha) and lablab was the lowest in Ukulinga (0.88 t/ha). Lablab was effective in suppressing weed biomass in Bergville (P < 0.05). Cowpea performed best in suppressing weed biomass in Ukulinga (P < 0.05). The results suggest that cowpea and lablab can be effective for weed suppression and therefore can be recommended for use in conservation agricultural systems.

Access to finance and market has been described as a predominant challenge confronting small and medium-sized enterprises (SMEs). Hence, this paper seeks to evaluate access to finance, market access and viability of SMEs. A quantitative research method and a purposive sampling technique were used to select the participants for this study. Respondents from retail, manufacturing, construction and agricultural SMEs operating in Durban, KwaZulu-Natal, were selected to complete the structured questionnaires. 310 questionnaires were returned out of 321 distributed. The study revealed a significant effect of access to finance (absolute value 0.425) and access to market (absolute vale 0.373) on SMEs’ viability with a 5% level of significance. Thus, it was concluded that access to finance uniquely accounted for the larger proportion of the variance in the regression model. Thus, this study suggests that owners of SMEs should pay greater attention to access to finance in running their businesses, and the Government should aid SMEs to market their products and keep their businesses viable. Public loans or the government supported loans should be made available for SMEs with soften requirements in order to stimulate economic growth.

Food security at the household level remains a major issue in South Africa and for many other developing countries, particularly those in Africa. As a means of ensuring food security in KwaZulu-Natal province, various food security intervention programmes were launched. Nonetheless, food security remains an issue among households in the province. This paper estimates the household food security status of the “One Home One Garden” (OHOG) beneficiaries against that of non-beneficiaries and assesses the determinants of household food security status in Maphumulo. A stratified random sampling technique was used to sample 495 households (including 330 OHOG beneficiaries and 165 non-beneficiaries). The status of household food security was estimated by means of a “Household Dietary Diversity Score” (HDDS). Additionally, a Household Food Consumption Score” (HFCS) tool was employed to supplement the HDDS. The results showed that food consumption patterns were characterized by medium (4.89) and average (4.22) HDDS for the OHOG beneficiaries and non-beneficiaries, respectively. Taking HDDS as a proxy for household food security, an independent samples t-test (Levene’s test—equal variances assumed) reveals a significant (p < 0.001) relationship between the sample means of the two groups. A greater proportion (65%) of the OHOG beneficiaries had an acceptable (≥35) HFCS level, whereas just over half (54%) of the non-beneficiaries fell in the borderline (21.5 to 35) HFCS level. The determinants of household food security status were elicited by means of a binary logistic regression model. The results revealed that education (p = 0.036), receiving infrastructural support (irrigation) (p = 0.001), and participation in the OHOG programme (p = 0.000) positively influenced the food security status of households, yet household income (p = 0.000) and access to credit (p = 0.002) showed a negative correlation. This paper proposes that government and developmental agencies, in their efforts to enhance food security through food security intervention programmes, should support households by investing in education and agricultural infrastructure, as well as giving priority to smallholder infrastructural irrigation support for households that largely rely on rain-fed systems.

Severe weather events associated with strong winds and flooding can cause fatalities, injuries and damage to property. Detailed and accurate weather forecasts that are issued and communicated timeously, and actioned upon, can reduce the impact of these events. The responsibility to provide such forecasts usually lies with government departments or state-owned entities; in South Africa that responsibility lies with the South African Weather Service (SAWS). SAWS is also a regional specialised meteorological centre and therefore provides weather information to meteorological services within the Southern African Development Community (SADC). We evaluated SAWS weather information using near real-time observations and models on the nowcasting to short-range forecasting timescales during two extreme events. These are the Idai tropical cyclone in March 2019 which impacted Mozambique, Zimbabwe and Malawi resulting in over 1000 deaths, and the floods over the KwaZulu-Natal (KZN) province in April 2019 that caused over 70 deaths. Our results show that weather models gave an indication of these systems in advance, with warnings issued at least 2 days in advance in the case of Idai and 1 day in advance for the KZN floods. Nowcasting systems were also in place for detailed warnings to be provided as events progressed. Shortcomings in model simulations were shown, in particular on locating the KZN flood event properly and over/underestimation of the event. The impacts experienced during the two events indicate that more needs to be done to increase weather awareness, and build disaster risk management systems, including disaster preparedness and risk reduction.

Climate change poses a serious threat to efforts by developing countries to ensure food security and poverty reduction. The National Development goals of South Africa envisage the agricultural sector as a key driver for job creation and economic growth. This article seeks to investigate the adaptive capacity of the Ncunjane farming community in Msinga, KwaZuluNatal in response to drought spells of 2010 and 2014. This article draws on data collected using both qualitative and quantitative methods in 2011 and later in 2015 with the data analysed through the Statistical Package for Social Science to determine significant correlations between variables. Analysis of the vulnerability and adaptive capacity is performed using conceptual framework. This study found that both smallholder farmers who engaged in livestock and crop production have experienced high cattle mortalities and stagnant crop productivity, which in turn put pressure on already constrained disposable household income because of increased food costs and agricultural input costs, particularly supplementary animal feed. Cattle owners were more vulnerable to drought because of poor risk management and thus became highly dependent on government to provide drought relief. Application for government drought relief was found not to be effective in cases of large herds of cattle. Variability of rainfall and prolonged heat spells has a significant impact on the sustainability of smallholder mixed-farming systems, leaving agriculture as a highly questionable form of livelihood for rural farming communities such as Msinga. The article recommends strengthened institutional mechanisms so that stakeholders should play a more meaningful role within provincial and local agriculture in leveraging government support but places emphasis on the adoption of innovative strategies that can potentially yield significantly resilient smallholder mixed-farming systems in the wake of climate variability.

Thesis (MScAgric)--Stellenbosch University, 2001.<br>ENGLISH ABSTRACT: With the advent of Globalisation, the need for improved competitiveness ill agriculture, as in all sectors, has become increasingly important in obtaining satisfactory levels of growth and development. International producers are competing for South African markets while local producers must not only defend these markets, but also seek out opportunities globally. Agricultural research has been identified as one of the more important agricultural support services contributing towards the goal of increased competitiveness. Innovation and new technology are central towards achieving satisfactory competitiveness, and in order for these to be adequately available, the agricultural research system in place must be effective and efficient in its tasks and responsibilities. The objective of this study was to determine whether or not the agricultural research systems of KwaZulu Natal and the Western Cape conform to the current challenges presented by the market, technology and economic environments. The effectiveness and efficiency of these systems regarding structural interactions, research investments and the involvement of the private sector was critically analysed with regard to the stakeholders within the system, namely: producers, co-operatives, private sector agribusiness companies and agricultural research institutes. The findings are discussed in terms of their implications for the agricultural sectors concerned and recommendations made for potential improvements and future areas of research. It was found that most of the structural interactions between the various stakeholders investigated were conducted inefficiently and have thus resulted in a lack of cooperation, poor relationship building, and sub-optimum productivity and growth. Furthermore, it was established that investment in agricultural research is too low. Although research expenditure growth rates and expenditure per fulltime researcher are high, most of the growth rates are on the decline and most of the organizations do not employ fulltime researchers, while the actual total amounts invested are low. Investment in market research for current products is satisfactory, while investment in market research prior to conducting research is poor. Finally, increased private sector involvement has not been realized. Incentives for greater private sector involvement based on profitability, have not been adequately developed. Of those companies who have recognized the need for increased commitment to research, all but one have predicted zero to low increases in research expenditure for the future, while current research expenditures are also low. There are many areas in which the agricultural research systems of the two provinces concerned must improve. A culture inductive of greater research spending and private sector participation should be fostered to overcome the causes and motives behind these problem areas. Currently, the research systems investigated seem incapable of effectively and efficiently supplying the agricultural sectors concerned with the much needed new technologies, innovations and research management necessary to adequately increase competitiveness. However, if all the shortcomings of the system are recognized and a new demand driven orientation adopted, the research systems of South Africa will in the future be more likely to promote increased productivity and growth in agriculture through greater competitiveness.<br>AFRIKAANSE OPSOMMING: Met die koms van In verenigde wêreldmark, het dit noodsaaklik geword dat die landbou - net soos ander bedryfsektore - mededingend moet wees vir bevredigende groei en ontwikkeling in dié sektor. Internasionale produsente ding mee om Suid- Afrikaanse markte, terwyl plaaslike produsente nie net hierdie markte moet verdedig nie, maar ook nuwe geleenthede in die buiteland moet soek. Landbounavorsing is as een van die belangrikste landbou-ondersteuningsdienste geïdentifiseer om mededingendheid te verhoog. Om voldoende mededingend te wees, is vernuwing en nuwe tegnologie van wesenlike belang. Vir dié doel moet die bestaande landbounavorsingstelsel doeltreffend funksioneer en sy take en verantwoordelikhede behoorlik nakom. Die doel van hierdie studie is om te bepaal of die landbounavorsingstelsels van KwaZulu/Natal en die Wes-Kaap die uitdagings van die huidige mark-, tegnologiese en ekonomiese omgewings die hoof kan bied. Die doeltreffendheid van strukturele interaksies, beleggings in navorsing en die betrokkenheid van die privaatsektor is krities ontleed aan die hand van die belangegroepe binne die stelsel, te wete produsente, kooperasies, private maatskappye en landbounavorsingsinstitute. Die implikasies van die resultate is vervolgens bespreek en aanbevelings is gedoen vir moontlike verbeterings en toekomstige navorsingsgebiede. Daar is bevind dat die meeste strukturele interaksies tussen die onderskeie belangegroepe wat bestudeer is, ondoeltreffend is. Daar is te min samewerking, weinig sprake van verhoudings bou, produktiwiteit is te laag en daar is te min groei. Daar is verder vasgestel dat daar te min in landbou-navorsing belê word. Alhoewel die groeikoerse van navorsingsuitgawes en uitgawes per voltydse navorser hoog is, is die meeste groeikoerse aan die daal, die meeste organisasies neem geen voltydse navorsers in diens nie en die totale besteding is laag. Belegging in marknavorsing vir bestaande produkte is bevredigend, maar belegging in marknavorsing voor navorsing aangepak word, is onbevredigend. Laastens is die privaatsektor nog nie voldoende betrokke nie. Daar bestaan egter nie genoeg aansporingsmaatreëls om die privaatsektor se betrokkenheid te verhoog nie. Van dié maatskappye wat wel die noodsaaklikheid van 'n groter verbintenis tot navorsing erken het, het almal behalwe een, nul tot lae verhogings in navorsingsuitgawes vir die toekoms voorsien, terwyl hulle huidige navorsingsuitgawes alreeds laag is. Daar is baie opsigte waann die landbounavorsingstelsels van die twee betrokke provinsies moet verbeter. Daar moet 'n kultuur ontstaan waar meer bestee word aan navorsing. Verder moet die privaatsektor meer betrokke raak om die omstandighede wat aanleiding gee tot die probleme, die hoof te help bied. Tans wil dit voorkom of die navorsingstelsels wat ondersoek is, nie daarin slaag om die betrokke landbousektore van die nuwe tegnologie, vernuwings en navorsingsbestuur te voorsien wat noodsaaklik is om mededingendheid te verhoog nie. Indien al die tekortkominge van die stelsel erken word en die korrekte aanpassings gemaak word, sal die navorsingstelsels van Suid Afrika in die toekoms 'n groter bydrae kan lewer om produktiwiteit te laat styg en groei in die landbou teweeg te bring.

Thesis(MPhil)--Stellenbosch University, 2014<br>ENGLISH ABSTRACT: This thesis documents a Participatory Action Research (PAR) project conducted from 2011 to 2013 in a rural communal area in southern KwaZulu-Natal, South Africa. The area is a microcosm of the global environmental and socio-economic polycrisis; with adult unemployment at 50 percent, 73 percent female-headed households, heavy dependence on government social grants and a food system reliant on purchased food. Eight, mainly female-headed households (the co-researchers), assisted by the student researcher, implemented and assessed a cropping system, designed on agroecological principles, on their abandoned garden plots. The objective was to grow culturally acceptable food crops to supplement their household diets and positively affect their food security. The student researcher provided the necessary infrastructure, including goat-proof plot fences, hand tools, a grain hammermill, seed, and fertiliser. The literature review, which also used early 1900’s photographs and contemporary isiZulu language as evidence, revealed the agroecological basis of pre-colonial agriculture. However, colonial and apartheid influences destroyed this knowledge base. The cropping system design utilized practices from this pre-colonial era combined with current agroecological techniques. The agroecological techniques employed on the plots included non-inversion tillage of planting pits using garden forks, precision placement of phosphate fertiliser and animal manures, open pollinated seeds, east-west orientated strip cropping, soil surface mulches, crop rotations including legumes and the use of chickens to control pests. Dryland crops included maize, beans, sweet potatoes, and butternuts, with small trial vegetable patches on some plots. The research identified a method to calculate the planting frequency of these vegetables to ensure a constant annual supply, however further research is needed. The dryland crops supplemented household diets between harvests. The formation of structured groups amongst the households proved vital to the success of the cropping system, providing mutual labour assistance, shared decision-making, building knowledge and moral support. The importance of dialogue and trust, reinforced by the student researcher’s ability to communicate in isiZulu with the co-researchers, formed the basis of both the PAR, and Focus Group Discussions(FGD), used to qualitative assess the cropping system. During these, the households reported a good understanding of the agroecological principles of the cropping system, a willingness to continue with it post research, and positive benefits, including better health, and money saved on food purchases, redirected to improve their asset base. The World Food Programme (2008) Food Consumption Score Analysis Method (FCS), modified to show the percentage contribution of homegrown food to the FCS, provided the quantitative assessment of the cropping system. The FCS scores rose during the research, with homegrown food contributing over a third of the FCS at times. The co-researchers suggested instituting group ‘stokvels’1to finance inputs and maintain infrastructure post research. The financial implications of these ‘stokvels’ was calculated. Due to the initial success of the PAR, the research recommends a method to extend the cropping system to more households, utilizing state finance to provide the infrastructure, and the co-researchers imparting technical knowledge through farmer-to-farmer extension.<br>AFRIKAANSE OPSOMMING: In hierdie tesis word verslag gedoen van ’n deelnemende aksienavorsingsprojek wat van 2011 tot 2013 in ’n landelike dorpsgebied in die suide van KwaZulu-Natal, Suid-Afrika, uitgevoer is. Die gebied is ’n mikrokosmos van die wêreldwye omgewings- en sosio-ekonomiese polikrisis, met volwasse werkloosheid op 50%, 73% huishoudings met vroue aan die hoof, swaar afhanklikheid van die staat se maatskaplike toelae en ’n voedselstelsel wat van gekoopte kos afhanklik is. In die studie het agt huishoudings, wat hoofsaaklik vroue aan die hoof het (die medenavorsers), met behulp van die studentenavorser, ’n verbouingstelsel, wat op agro-ekologiese beginsels gegrond is, op hul verlate tuingrond geïmplementeer en geassesseer. Die doel was om kultureel aanvaarbare gewasse te verbou om hul huishoudelike dieet aan te vul en hul voedselsekerheid positief te beïnvloed. Die studentenavorser het die nodige infrastruktuur verskaf, met inbegrip van bokbestande omheining, handgereedskap, ’n graanhamermeul, saad en kunsmis. Die literatuurstudie, waarin foto’s uit die 1900’s en moderne Zoeloe as bewyse gebruik is, toon die agro-ekologiese grondslag van prekoloniale landbou. Koloniale en apartheidsinvloede het egter hierdie kennisbasis vernietig. Die verbouingstelselontwerp was gegrond op praktyke uit hierdie prekoloniale era gekombineer met moderne agro-ekologiese tegnieke. Hierdie tegnieke het ingesluit nie-inversie-grondbewerking van plantgate met gebruik van tuinvurke, presisieplasing van fosfaatkunsmis en dieremis, oop bestuifde sade, oos–wes-georiënteerde strookverbouing, grondoppervlak-deklae, wisselbou met onder andere peulgewasse en die gebruik van hoenders om peste te beheer. Droëland-gewasse het ingesluit mielies, bone, soetpatats en botterskorsies, met klein toetsgroenteakkers op sommige stukke grond. ’n Metode is in die navorsing geïdentifiseer om te bepaal hoe gereeld hierdie groente geplant moet word om ’n konstante jaarlikse voorraad te verseker. Verdere navorsing is egter nodig. Die droëland-gewasse het huishoudelike diëte tussen oeste aangevul. Die vorming van gestruktureerde groepe onder die huishoudings het noodsaaklik geblyk te wees vir die sukses van die verbouingstelsel, waardeur wedersydse hulp met arbeid, gedeelde besluitneming, die bou van kennis en morele ondersteuning gebied is. Die belangrikheid van dialoog en vertroue, wat versterk is deur die studentenavorser se vermoë om in Zoeloe met die medenavorsers te kommunikeer, het die grondslag gevorm van die deelnemende aksienavorsingsprojek asook die fokusgroeponderhoude, wat gebruik is om die verbouingstelsel kwalitatief te assesseer. In hierdie onderhoude het die huishoudings verslag gedoen van hul grondige begrip van die agro-ekologiese beginsels van die verbouingstelsel, hul gewilligheid om ná die navorsing daarmee voort te gaan, asook die voordele wat dit bied, soos beter gesondheid en geld wat op voedselaankope gespaar is, wat heraangewend is om hul batebasis te verbeter. Die Wêreldvoedingsprogram (2008) se Food Consumption Score- (FCS-)ontledingsmetode, wat aangepas is om die persentasie bydrae van selfgekweekte voedsel tot die FCS aan te toon, is gebruik vir die kwantitatiewe assessering van die verbouingstelsel. Die FCS-tellings het tydens die navorsing toegeneem, met selfgekweekte voedsel wat by tye tot meer as ’n derde tot die FCS bygedra het. Die medenavorsers het voorstel dat ’n stokvel gestig word om insette te finansier en die infrastruktuur ná die navorsing in stand te hou. Die finansiële implikasies van hierdie stokvel is bereken. Op grond van die aanvanklike sukses van die deelnemende aksienavorsingsprojek stel die navorser ’n metode voor om die verbouingstelsel na meer huishoudings uit te brei met behulp van staatsfinansiering om die infrastruktuur te verskaf asook die oordrag van die medenavorsers se tegniese kennis na ander boere.

For many poor rural South African communities, involvement in agriculture remains one of their most secure livelihood strategies. For the majority of these people, indigenous knowledge and the use of local materials, resources and skills is often the only asset they possess. The Ezemvelo Farmers Organisation (EFO) from the community of Embo in KwaZulu-Natal is one such group of rural people befitting this description. In the absence of financial resources to purchase relatively expensive agricultural inputs, accompanied by a lack of infrastructural development in their community, EFO farmers have become organic farmers by default. EFO members produce mainly traditional organic crops. However, little has been documented about the potential value of trade in these products. The purpose of this study was to explore potential marketing opportunities for traditional organic products through the mobilisation of indigenous knowledge, skills, and natural resources to improve the livelihoods of EFO members. A research team of three postgraduate students, each involved in his/her own independent study, worked in collaboration to collect relevant research information. Five data collection tools were used to collect this information. These were a household survey, a sustainable livelihoods analysis, a forcefield analysis, a stakeholder analysis, and a workshop. Research results showed that there are five stakeholders involved in EFO activities, each with his/her own personal interests. EFO members mainly produce amadumbe, sweet potatoes, and potatoes, which they market to a packhouse, the local community, and to hawkers. Other crop varieties are produced for household consumption and small quantities are sold to the local community and hawker markets. Farmers obtained a slightly higher price for crops sold to the packhouse as compared to the other two markets. The packhouse was the farmers' largest market for the 2002 season. However, the packhouse market was unsustainable for farmers because of problems due to the delays in payments for produce, the high quantities of crops that are rejected because they did not meet the quality control standards of the packhouse, and problems due to the unreliability of transport from Embo to the packhouse. The majority of EFO members' farms were also found to be unprofitable due to the high costs of inputs and losses to production. Constraints such as a shortage of kraal manure for soil conditioning, unfenced properties, a lack of water for irrigation, and the unavailability of a tractor for ploughing were found to be contributing factors to the unprofitability of member farms. Recommendations for improving marketing and profitability were that projects involving farmers should be regularly evaluated, EFO members seek business management skills, direct contracting agreements with their suppliers, explore value added products, and for Government to play a role for rural enterprise development to take place.<br>Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 2002.

In the past, the indigenous knowledge of soils of small-scale farmers in South Africa has been largely ignored in scientific research. Hence the use of scientific approaches to land evaluation has often failed to improve land use in rural areas where understanding of the prescriptive scientific logic is lacking. Despite this, it is clear that local people and smallscale farmers have knowledge of their lands based on soil and land characteristics that remain largely unknown to the scientific community. It is therefore important for researchers to understand farmers’ knowledge of soil classification and management. To address this issue, a study was conducted in the uMbumbulu area of KwaZulu-Natal to investigate the use of indigenous knowledge as well as farmers’ perceptions and assessments of soil fertility. A preliminary questionnaire was designed to explore indigenous knowledge in a group interview that was conducted prior to the study. Another questionnaire was used to elicit indigenous knowledge from 59 randomly chosen homesteads representative of the population of Ezigeni and Ogagwini villages. Six homesteads were chosen for further detailed information on the cropping history, knowledge specific to the cultivated lands, detailed soil description and fertility. Soil samples were taken from these homesteads under different land uses (taro, fallow, veld and vegetable) at 0-30 and 30-60 cm depth for laboratory analysis. This was done to determine the effect of land use on soil physical and chemical properties and soil microbial activity. For scientific evaluation a general purpose free soil survey was conducted to produce land capability and suitability maps. Farmers identified ten soil types using soil morphological characteristics, mainly soil colour and texture. These soil properties were also used in the farmers’ land suitability assessment. In addition, slope position, natural vegetation and village location were used to indicate land suitability. The amount of topsoil was also used in land evaluation. However, slope position was considered the most important factor as it affects the pattern of soils and hence their suitability. Soils on the footslope were considered more suitable for crops than those found on the midslope and upslope. The yield difference observed between villages, which were higher in Ogagwini than Ezigeni, was also used as a criterion for evaluation. Farmers attributed these yield differences for various crops to the effect of soil type on productivity. In support, scientific evaluation found that Ezigeni village had a number of soils with a heavy textured, pedocutanic B horizon and hence a relatively shallow effective rooting depth. Moreover, the Ezigeni village land suitability was limited in places by poor drainage and stoniness. These limitations were rarely found for the Ogagwini village soils. Farmers had a total of six comprehensive and well defined soil fertility indicators, namely crop yield, crop appearance, natural vegetation, soil texture, soil colour and presence of mesofauna. Results showed that farmers’ fertility perceptions are more holistic than those of researchers. However, despite this, their assessment correlated with soil analysis. There was a close relationship between scientific and indigenous suitability evaluation for three commonly cultivated crops (taro, maize and dry beans). This was further substantiated by yield measurements which were significantly higher for Ogagwini as rated by both farmers and scientific evaluation as the more suitable. The significant agreements between the scientific and indigenous approaches imply that there are fundamental similarities between them. Recognizing this and subsequently integrating the two approaches will produce land use plans relevant and profitable for both small-scale farmers and scientists.<br>Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2010.

This study explores the perceptions of the value of community gardens by members and the relationship between this activity and homestead farming activities in Ogagwini, Umbumbulu District, KwaZulu-Natal. Establishing and supporting community gardens is consistent with the strategies adopted by South African national and provincial government to alleviate poverty, address food security and improve livelihoods for rural people. However, there is a lack of literature available on why rural people choose to involve themselves in community garden projects and whether these reasons are those intended by policy makers. There is abundant research on community gardening – most of it either urban or not specific as to setting. This literature is useful for the generic information it provides, but does not provide the scope of understanding that is unique to rural community gardening in South Africa. Thus this study contributes to understanding rural community gardens and possible adjustments needed by extension workers and development strategies to ensure effective food gardening practices in rural KwaZulu-Natal. The first extension facilitated community garden activities in Ogagwini were established in 1993 with the support of the provincial DAEA. Some community garden members are also members of the Ezemvelo Farmers Organisation (EFO), a group of farmers engaged in commercial small-scale farming. This research attempted to find out how community gardening activities were related to small-scale commercial homestead activities. Specifically, the study sought to investigate issues such as preferences among farmers between community gardens and homestead farming; the social and economic benefits derived from community gardens; and perceptions around environmental/ecological issues surrounding community gardens and homestead farming. A survey questionnaire on community garden activities and perceptions was given to EFO members and used to identify participants for this study. Committee members of the EFO (also members of community gardens) arranged for five gardens to be investigated. In-depth data was collected at the actual garden sites using semi-structured focus group discussions and participant observation. The data from the survey questionnaire was verified and clarified by semi structured probing during these discussions. A spiral approach was used to organise responses and make sense of the data within social, economic, and environmental themes. After three garden visits, no new knowledge was forthcoming and due to time constraints the study was limited to these three groups. The study found that there were no distinct linkages between homestead farms and community gardens, but that the systems operated on different principles. Community gardens were used to produce cabbages, carrots, beetroot, onions, green peppers and spinach mainly for consumption, whereas homestead farms produce field crops such as maize, amadumbes (taro), sweet potato, potatoes, pumpkins and peanuts. The study further identified social and economic benefits and environmental impacts and reinforces the importance of knowledge sharing amongst participants. The main benefits identified were income generation, sharing of knowledge and technical support The Department of Agriculture should carefully address sustainability issues when planning and implementing community gardens. This would include being able to carry on in the absence of an agricultural extension officer. Training programmes need to ensure that learning is transferable; that it is not overly commodity or technology specific and includes promotion of environmental awareness. This study has highlighted a number of potentially valuable issues for further situated research in the area of farming protocols, markets and the social value of community gardening within rural communities.

The 48 members of the Ezemvelo Farmers' Organisation (EFO) in KwaZulu-Natal (KZN), South Africa (SA), that were fully-certified as organic farmers were surveyed during October-December 2004 to assess their perceived level of satisfaction, trust, cooperation and commitment in a formal supply chain producing amadhumbes (a traditional vegetable tuber), potatoes and sweet potatoes for a major SA supermarket group. Empirical recursive models show that a high level of satisfaction in the working relationship results in these farmers trusting the pack-house agent more. High levels of trust, in turn, lead to higher levels of both commitment to, and cooperation in, the supply chain. A simultaneous-equation model showed that EFO farmers with higher levels of commitment tend to be more cooperative, and that members with higher levels of cooperation tend to be more committed toward the working relationship. These results suggest that strategies to improve the working relationship with the pack-house agent need to promote satisfaction, trust, cooperation and commitment. For example, co-investment in better crop storage facilities at farm-level would promote satisfaction and hence trust. There is also scope for more cooperation in the planning of new organic crop products to grow and market, and to remove some price uncertainty by giving EFO farmers more information about prices that they will be paid by the pack-house agent in this supply chain. In addition, satisfaction and, hence, trust, cooperation and commitment may be improved by adopting a formal contract between the EFO farmers and the pack-house agent to replace the current, incomplete verbal contract that governs trading. Some issues that may be addressed in this contract are improved communication systems via regular meetings, renegotiations of trading terms so that farmers can benefit from positive changes in organic crop prices; guidelines for paying farmers more quickly by the pack-house agent; mechanisms to trace crop quality to a specific farmer to avoid free riding; and penalties for breaching the contractual arrangements. The 48 EFO farmers were also asked to give their perceptions of the main constraints on organic crop production and marketing in the formal organic crop supply chain. They perceived that uncertain climate, unavailability of tractor or draught power when needed, delays in payments for crops sent to the pack-house, lack of affordable inputs (particularly labour and manure), a lack of cash and credit to finance inputs, lack of affordable transport to market crops, more work than the family can handle, a lack of manure to purchase; and a lack of crop storage facilities and telephones to negotiate sales as the current top 10 constraints. Principal Component Analysis summarized the underlying dimensions in the 20 constraints ranked by these farmers as indicating "lack of market information and lack of market power"; "crop production expansion constraints"; "commitment to crop area expansion"; "lack of liquidity"; "lack of proper storage facilities"; and "lack of information about alternative markets". Potential solutions to better manage these perceived constraints include: improved risk management practices (e.g., supplemental irrigation, water-harvesting and small boreholes), improving access to tractor services via improved tractor scheduling or using local contractor services, quicker pack-house delivery payments, improving quality inspection at the departure points at EFO farm-level to reduce crop rejection rates and "free riding" by producers of lower quality organic crops, more interaction with the retailer to promote sales of organic crops, providing advice on how the EFO farmers can improve their bargaining power, and providing more information (e.g. crop prices) about other organic markets and changing consumer preferences. Apparently, the costs and benefits of these potential solutions, and how they will be financed, need to be evaluated. Real accounting marketing margins since 2001 showed that the farmer's share of the consumer's rand for the 48 fully certified organic EFO farmers rose, while their net returns (selling price less accounting costs) were lower than those of the pack-house agent and hawkers selling at the Isipingo market on the South Coast of KZN. Net returns for the 48 EFO farmers also seemed to be relatively higher if they sold through the informal supply chain (hawkers) rather than the formal supply chain. The EFO farmers' net returns may be improved by lowering operating costs and by aggressive marketing to customers willing and able to pay a price premium for organic crops. These farmers may also consider performing some of t he marketing services themselves (e.g. crop cleaning, grading and packaging) if they have the skills and can access more finance. There are, however, hidden benefits from maintaining the formal supply chain relationship, as the pack-house agent helped to secure tractor services and fencing, and facilitates access to the retailer.<br>Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.

The Ezemvelo Farmers’ Organisation (EFO) is a certified organic smallholder group in KwaZulu-Natal province (South Africa) that exists as an institution to improve smallholder access to niche markets by reducing unit production and transaction costs. The study is motivated by the need to understand drivers of collective action, prevalence of internal group free-riding, and the impact of contract terms on contract performance. These three theoretical concepts are pertinent in understanding organisational and institutional issues affecting the performance of smallholder organic farming groups and in formulating policies to promote the performance of such groups. The study relies on the theoretical foundations of collective action, free-riding and contracts found within the realm of New Institutional Economics (NIE). These theories, though separate, are in fact related in certain respects. Collective action in smallholder groups, apart from being a function of a plethora of socio-economic factors, including transaction costs, could be constrained by free-riding within the group, which in turn could be influenced by flawed contractual arrangements. This study of collective action focuses on 200 farmers drawn from a sample survey of 49 non-EFO members, and a census survey of 103 partially certified and 48 fully certified EFO members. A ‘collective action’ model investigates the impact of perceived benefits and savings on production and transaction costs attributed to collective action by drawing comparisons between EFO members and non-members using a multinomial logit model. The study of free-riding uses data from 151 members of the EFO to construct an index of free-riding within the group using principal components analysis (PCA). A ‘contract model’, which also focuses on EFO members only, attempts to measure the impact of verbal contract provisions on contract performance in addition to evaluating the determinants of preferred contract terms using a combination of PCA, Ordinary Least Squares (OLS) regression, and logit models. Results indicate that continued participation in EFO is not influenced by the age or gender of the farmer, but positively influenced by growth in the net benefits of participation, and negatively by an increase in the size of the household’s cropland or on-farm earnings. With respect to production and transaction costs, the results suggest that EFO has reduced fully certified members’ concerns that crops would be damaged by livestock or constrained by inadequate technical information. However, this is not the case for other problems such as price uncertainty in conventional markets, a lack of affordable operating inputs, a lack of affordable transport, and a lack of communications infrastructure. The index of free-riding behaviour constructed using principal components analysis suggests that free-riding poses a serious threat to EFO’s collective marketing efforts. Ordinary Least Squares regression analysis of the index scores shows that members who are male, poorly educated, partially certified, aware of loopholes in the grading system, and who do not trust the buyer are more likely to free-ride. Benefits accruing to EFO members are limited and there is substantial confusion among members about the terms of EFO’s verbal contract with the pack house that purchases their organic produce. Ordinary Least Squares regression analysis of the impact that perceived contractual terms have on quantities delivered to the pack house yielded interesting findings. Perceptions that delivery calls are made by the buyer, that grading procedures are flawed and that prices are not jointly established were found to reduce quantities delivered to the pack house, after controlling for differences in farm and farmer characteristics. Logit models estimated to identify the determinants of preferred contract clauses indicate that farmers with higher levels of formal education and farm income, and lower levels of experience, favour a written contract over a verbal contract. Similarly, farmers with higher levels of formal education and lower levels of family farm labour favour a contract denominated by area rather than weight. It is concluded that EFO should recruit households that rely on farming for income and which are land constrained. EFO is more likely to survive if it continues to secure fully subsidised information, transport, fencing, and certification services for its members, and if it improves the benefits of participating by synchronising harvest and delivery dates, negotiating price discounts for organic inputs, and by maintaining an office with telephone, fax and postal services. In the longer-term, EFO should address institutionalised free-riding by issuing tradable ownership rights. In the short-term, EFO must engage with the pack house (buyer) to remove flaws in the grading process that conceal the origin of low quality produce. Transparent and mediated negotiations leading to an incentive compliant contract with the buyer may also help to build trust and reduce free-riding within EFO. It is also recommended that the terms of EFO’s contract with the pack house should be revised so that; (a) delivery calls can be made by either the pack house or by EFO during specified periods and with reasonable notice, and (b) grading procedures are fully transparent and ensure traceability so that losses caused by poor quality can be internalised to members who deliver inferior produce. In addition, it is important that prices be negotiated at the beginning of each season and that the contractual parties have recourse to pre-agreed facilitators and an arbitrator to resolve disputes on price and quality. A written contract is recommended to support these more complex terms, with the proviso that the contract is explained to current and prospective members, and that growers are fully informed of their rights and obligations.<br>Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2008.

South Africa as other African countries has not been spared from the rural poverty. The South African government is trying to address this problem through various government departments. One such ministry trying to address rural poverty is the Ministry of Agriculture, working together with the provincial Ministries of Agriculture in different provinces. The provision of appropriate agricultural extension services is regarded as a tool that may be used to address rural poverty and development in South Africa’s rural areas. Appropriate extension services will depend on the knowledge management system applied by the organisation making it innovative and responsive to the needs of the farmers. The objective of this research was therefore to identify knowledge management systems applied by extension workers to support community garden farmers in the uMgungundlovu District Municipality in KwaZulu-Natal. To address the objective, qualitative research methods, namely focus group discussion and semi-structured interviews, were used. In this research, it was evident that the extension workers were not efficiently managing knowledge within their department, among themselves as well as among the farmers. The extension workers have potential knowledge management methods in place, such as departmental meetings. However, the extension workers’ practices do not capture the true essence of knowledge management. There is no evidence that knowledge gained by extension workers during meetings and informal discussions in the organisation is translated into learning, which could lead to the development of new knowledge by the extension workers. The extension workers claimed that they are using appropriate methods to learn from the farmers and to share knowledge with them. However, the farmers do not believe that the extension workers make use of any methods to encourage knowledge sharing and learning. It is thus evident that extension workers do not integrate knowledge gained from the farmers into the improvement of their own agricultural extension practices. Agricultural extension organisations therefore need to adopt methods that encourage learning, reflection and engagement with the knowledge gained from the organisation and the farmers for real knowledge management to take place. This, in essence, will lead to the creation, sharing, utilization, absorption and transformation of knowledge.<br>Thesis (M.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2011.

Lower reaches of rivers as well as estuaries are regarded as South Africa’s most productive ecosystems due to the important functions such as providing nursery areas and feeding sites for juvenile macro-invertebrate and fish species they perform. Furthermore, ecologically healthy estuaries are not only of critical importance since they facilitate the provision and recirculation of nutrients, they also provide conduits for fish migrations into the fresh water system and act as buffers during floods. In South Africa, these functions are continuously being threatened by residential and/or industrial developments. It is thus essential to determine the ecological integrity (structure and function) of these systems. An Ecological integrity study was carried out on the selected rivers in Kwazulu Natal between 2015 and 2017. This study was assessed in terms of selected abiotic drivers on specific biological responses. The study was carried out according to the guidelines of the ecological determination methodologies and the resource directed measures for aquatic resources as set out by the Department of Water Affairs and Forestry, South Africa. Surveys were carried out during summer and winter seasons. Abiotic and biotic monitoring was carried out at four sites along each estuary. The abiotic component such as sediment composition and physio-chemical properties of the water was analyzed using standard methods. The biotic and abiotic components were analyzed using various indices, where applicable. The ecological integrity of the system can be accessed on the basis of its ability to carry out its natural functions. Results showed the various anthropogenic activities in the upper reaches of each river contributed to the high modified state of some of these rivers’ unacceptable water quality, loss and/or modification of habitat and an altered hydrological pattern due to impacts by agricultural, industrial and domestic uses. The ecosystem services of the lower areas of the rivers under investigation are used extensively through sugarcane agricultural activities and heavy industries works inclusive of sand mining and rural sewage-treatment. These activities affect the ecological integrity of the rivers and ultimately the estuaries. This study aimed at determining the current state of ecological integrity of five selected rivers in KwaZulu Natal and to establish trends between current and historical periods for the evaluation of changing trends in ecological integrity. Abiotic and biotic indicator components were used to ascertain changes in the surrounding environment as well as to determine the ecological integrity of these rivers. Monitoring of water quality, sediment grain size, moisture and organic content as well as habitat state, macro-invertebrates and fish assemblages was undertaken. The following variables water temperature, chemical oxygen demand (COD), electrical conductivity (EC), pH and total alkalinity (TAL) as well as salts, nutrients and toxics were investigated to provide indications as to the state of the water-quality of these rivers. The Target Water Quality Requirements (TWQR) as developed by the Department of Water Affairs and Forestry for domestic use (Volume 1) and Aquatic Ecosystems (Volume 7) were used to evaluate the quality of the water sampled in this study. Historical data obtained from previous studies of similar study areas have also been evaluated. Sediment analyses were performed according to the protocol set out by the United States Environmental Protection Agency. As a result of the abiotic drivers, results showed that the invertebrate reside in modified state. Physio-chemical, geomorphological and hydrological changes in this system resulted in the rivers’ suffering a loss in both biological and ecological function as well as aesthetic value. It is apparent from the above that there is not a need for rehabilitation but also a need for effective and continuous management strategies. These strategies can only be successful if the bio-monitoring of the system includes the effects at both economical and social levels. The water quality of the rivers under this investigation was found to be in a slightly modified state with the majority of water quality parameters falling within the target values. Water quality parameters of the lower Thukela River, not within the required target, was highly elevated and could possibly cause negative impacts on the river functionality. The water quality parameters of Umvoti river, Umdloti river and uMngeni river were seriously modified. The sediment clearly indicated that the organic content of the all the rivers was low and directly relating to the possibility of erosion and transportation taking place in the Rivers. The removal of riparian vegetation by agricultural activities, sand mining and water abstraction contributed to the destruction of the habitats along all these rivers. The South African Scoring System, version 5 (SASS 5), the Macro-invertebrate Response Assessment Index (MIRAI) and multivariate statistical analyses were implemented in order to determine the ecological integrity of the rivers. Results revealed that the SASS 5 integrity classes were generally one class higher than the integrity classes of MIRAI. The Fish assemblage methods used to determine fish samples included electro-narcosis and a 5m wide 12mm meshed seine net. Impacts on the ecological integrity of the Rivers under investigation have been assessed by various sources. To protect the current ecological integrity and further destruction of the rivers under investigation, direct involvement by the relevant authorities is of paramount importance.<br>Agriculture and Environmental Science<br>D.
