A bibliometric review of vegetation response to climate change
(Springer, 2021-10-25) Afuye, Gbenga Abayomi ; Kalumba, Ahmed Mukalazi ; Busayo, Emmanuel Tolulope ; Orimoloye, Israel Ropo
Global assessment of vegetation response to climate change (VRCC) studies was conducted to reveal the research evolution, current research hotspots and better understanding of dominant themes in VRCC areas of research from 1992 to 2019 through the use of bibliometrics. A total of 186 articles with the search term “Vegetation response to Climate change” were retrieved using the Web of Science (WOS) database. The annual growth rate of 10.3% connotes that research on VRCC has been increasing over time during the survey period. Average citations per article experienced many fluctuations over the years rather than maintaining the same growth rate, which connotes that this field of research reached was unstable in terms of average total citation per document. Results show that China ranked first followed by the USA and the UK, and this shows the dominance of these countries on VRCC studies over the years in review. Results from corresponding authors’ nationalities show that multiplecountry publications are relatively low compared to articles from single-country publications which showed a dominant trend. Hence, we can infer that most studies on VRCC were sustained by single-country publications. Results from this study revealed top-cited articles, the top global distribution of documents, academic collaboration, most relevant keywords and Word TreeMap of high-frequency keywords. The findings of this study show that “temperature” is in a central position in all keywords with the largest significant appearance in the field. In conclusion, the findings from this study may be applicable for planning and managing vegetation and forest ecosystem research and provide hints for future development.
Agrarian question in South Africa: an evaluation study of the land redistribution for agricultural development (LRAD) programme in selected areas of the Buffalo City
(University of Fort Hare, 2010) Gebeza,Mahlubandile
This study is based on the view that the 'agrarian question of the dispossessed' is not yet resolved in South Africa. Since the early '90s, the South African government embarked on a land reform programme that was meant to contribute towards the creation of a better life for the historically dispossessed individuals. Land was given to land reform beneficiaries as grants. However, according to suggestions made by non-governmental organizations, community-based groups and the media, the land reform programme has generally not had any impact and that farms/projects assisted have either collapsed or are not functioning to the levels expected. This is the main reason why the study is conducted: to examine factors that explain why the agrarian question is not yet resolved in South Africa. The purpose is to bring -about -corrective measures which would result in stopping the wastage of funds that could be better utilized elsewhere.
Agricultural Expenditure ror Economic Growth and Poverty Reduction in Zimbabwe
(University of Fort Hare, 2012-04) Mapfumo, Alexander
A vibrant and an efficient agricultural sector would enable a country to feed its growing population, generate employment, earn foreign exchange and provide· raw materials for industries. The agricultural sector has a multiplier effect on any nation's socio-economic and industrial fabric because of the multifunctional nature of agriculture. The main objective of this study was to investigate how government expenditure on agriculture has affected economic growth in Zimbabwe from 1980-2009. The Log linear growth regression model was employed where gross domestic gross was the dependant variable, and the explanatory variables are the factors which affect it which include government agricultural expenditure. The expenditures of government on agriculture were divided into three functions namely extension, credit assistance and R & D.
An Analysis of the Characteristics and Constraints of Small Holder Commercial Farmers in the Transkei Region, The Eastern Cape , South Africa
(University of Fort Hare, 2000-01) Nompozolo, Sivelile
The majority of the poor in South Africa are involved in subsistence Agriculture. An increase in productivity of the production of staple crops would be one direct way of increasing income of those households as well as increasing the per capita availability of staples. The increased availability of staples could also release resources that could be used· to purchase foodstuffs for a better balanced diet and therefore contribute to the improvement of the nutritional status of the household. The general problem of agricultural development may well be the most critical development issue in Transkei (Transkei Land Reform Research Group; 1995).
Analysis of decision making in smallholder irrigation practice: a case study of Shiloh and Zanyokwe irrigation schemes in central Eastern Cape, South Africa
(University of Fort Hare, 2014) Agholor, Azikiwe Isaac
The study was conducted in Zanyokwe and Shiloh smallholder irrigation schemes located in Eastern Cape Province at Amathole and Chris Hani districts respectively. The choice of Zanyokwe and Shiloh smallholder irrigation scheme for this study is mainly supported by the fact that it had a substantial level of crop farming activity taking place especially at Zanyokwe while the Shiloh smallholder irrigation specialises dairy farming. The study examined decision making in smallholder irrigation practice with particular reference to Shiloh and Zanyokwe irrigation schemes. The general objective of the thesis was to analyse and model the determinants of SIS farmer’s decision making. The specific objectives of the study are as follows: to investigate the determinants of decision making among smallholder irrigation farmers; to examine the relationship between household and farm characteristics and institutional factors that explain decision making in smallholder irrigation scheme; assess the contribution of smallholder irrigation farming to household food security; and determine the production and marketing constraints of smallholder farmers‟ in both schemes. The theoretical and conceptual framework of the study gave a detailed discussion on the determinants of decision making of households. The theories used to understand household behaviour under different assumptions were variously discussed. Comprehensive illustrations of analytical framework of the study were also conceptualised. This study used a survey design, quantitative and qualitative research methodologies involving the use of questionnaires and focus group discussions. The data was coded and analysed using the Statistical Package for Social Science (SPSS). However, frequencies, percentages, bar and pie chart was also computed to describe the data. In consideration of the conceptual framework of the study, the agricultural household model was adopted to analyse smallholder farmer’s household decision making Twenty one explanatory variables identified in the conceptual framework of the study were discussed and some of these identified variables were incorporated into the model. The logistic regression model was used as a method of analysis because it can estimate the probability of a certain event occurring and it accommodates a lot of variables which can be ranked in order to illustrate which variables are significant. In the binary logistic model used, seven variables (farm experience, size of farmland, land rights/PTO, water sufficiency, farm asset, market information and production variation) out of the twelve predictor variables were found to have significant effect on influencing household decision making in Shiloh smallholder irrigation scheme, while five variables (gender, age, education, road distance and extension access) were not significant. Of the seven significant variables, four had positive signs (land rights/PTO, water sufficiency and market information); which means that an increase in either of these variables may be associated with an increase in household decision making in Shiloh. The other three predictor variables (farm experience, farm asset and product variation) had negative signs; this means an increase in either of these variables may be associated with a decrease in decision making. In Zanyokwe, six variables (farm experience, land rights/PTO, water sufficiency, farm asset, market information and production variation) out of the twelve predictor variables were found to have significant impact on influencing household decision making, while six variables (gender, age, education, size of farm land, road distance and extension access) were not significant. Of the six significant variables, two had positive signs (water sufficiency and farm asset); which means that an increase in either of these variables may be associated with an increase in household decision making in Zanyokwe. The other four predictor variables (farm experience, land rights/PTO, market information and product variation) had negative signs; this means an increase in either of these variables may be associated with a decrease in decision making. The study concludes that smallholder agriculture is essential for employment generation and food security of households. It is apparent that household food security will not be achieved without giving attention to the role played by smallholders‟ farmers in South Africa. It is pertinent to promulgate an efficient policy programme to address the diversity of smallholders‟ situations and identify the main constraints on investment. Therefore, all spheres of government, the private sector and NGOs should consider investment in smallholder agriculture through coordinated strategies and political support. This study also recommends that government should develop a strategic Smallholder Investment Plan which would improve investments in smallholder agriculture.
Analysis of entrepreneurial behaviour of smallholder irrigation farmers: empirical evidence from Qamata irrigation scheme
(University of Fort Hare, 2014) Chitsa, Gilbert
Albeit much effort having been put to review the performance trend of smallholder irrigation farmers in South Africa. However, there seems to be a paucity of information regarding the level of entrepreneurship on these farmers. Most research works on smallholder irrigation farmers have mainly focused on livelihoods trajectory providing a review on how the welfare of the rural poor has been transformed after the introduction of irrigation schemes. With most research evidence indicating a high degree of underperformance on most smallholder irrigation schemes, this research attempted to investigate the level of entrepreneurship among the small holder irrigation farmers. In order to achieve the main research objective, a sample of 110 farmers drawn from Qamata irrigation scheme was interviewed and each farmer’s performance on the nine components of entrepreneurship was assessed. The aspects assessed to determine the farmer’s entrepreneurial behaviour were: planning ability, risk taking, achievement motivation, leadership ability, Cosmo politeness, decision making, and innovativeness and farming knowledge. Basing on previous studies which indicated entrepreneurial behaviour to be influenced by several factors the study also analysed the determinants of entrepreneurship among the irrigation farmers and a binary logistic regression model was used to establish the connection between various independent variables and the farmers’ entrepreneurial performance given as a total score of the nine components. Though the findings of the study revealed a prevalently low level of entrepreneurship among the smallholder irrigation farmers on Qamata irrigation scheme, a high proportion of the respondent farmers (65.5% and 60.5%) showed to have a high degree of achievement motivation and decision making ability, respectively. The observed trend thus reflected that smallholder farmers have a potential to become entrepreneurs and are willing to succeed. The binary model results revealed that the prevailing land tenure system will be a strong determinant of the farmer’s level of entrepreneurship. Equally, levels of training in farming, motive for farming and information seeking tendency also proved to have a significant influence on the degree of farmer entrepreneurship. Based on the results of this study recommendations have thus been drawn on the need for policies and practices aimed at promoting entrepreneurship and not dependency among farmers. Key focus areas identified include: the need to revise the current land tenure system on irrigation schemes, intensify on entrepreneurship training for both farmers and extension officers and regular on-farm training on new technologies.
Analysis of marketing channels used by smallholder crop farmers in Vryheid (Abaqulusi) Municipality, Kwazulu-Natal
(University of Fort Hare, 2014) Ntshangase, Muziwandile Gift
A total of 120 structured questionnaires were administered to analyse marketing channels used by smallholder crop farmers, at Abaqulusi Municipality, Vryheid and KwaZulu Natal Province, South Africa. Research methodology consisted of research design, sample frame, sampling procedure, data collection and data analysis which were used in the study. Descriptive statistics analysis was used, where frequencies and percentages of the variables were indicated. Variables which were measured included demographic socio-economic profile of survey household heads where age, marital status, educational level, occupation other than farming, land ownership, household size and gender of the household heads.The results show that the statistically significant variables (gender, household size) at 5% level positively affect smallholder crop farmers’ access to market information, expertise on grades and standards, availability of contractual agreements, existence of extensive social capital, availability of good market infrastructure, group participation and reliance on tradition. These findings suggest that an adjustment in each one of the significant variables can significantly influence the probability of participation in either formal or informal marketing, and hence their marketing channels. In the light of the foregoing research findings, several policy options were suggested. These include encouraging collective action, promotion of contract farming, ensuring the availability of market information to all farmers, encouraging value addition and investment in rural infrastructure.
The analysis of the economic impact of climate change on maize production under different farming systems : the case of smallholder farmers in Jozini Municipality, KwaZulu Natal Province, South Africa
(University of Fort Hare, 2014) Nxumalo, Bongiwe G.
Maize is the most grown crop by the farmers in Jozini. Therefore, the main objective of the study was to assess the economic impact of climate change on maize production under different farming systems in Jozini Municipality in KwaZulu Natal (KZN). The study was looking at the smallholder farmers producing maize under dryland and irrigation system. A total of 100 farmers were selected for the study (40 from dry-land and 60 from irrigating farmers). Cluster and random sampling procedures were used to select the sample. Questionnaires were used for the collection of primary data, from the respondents (maize farmers). Data was analysed using descriptive statistics (frequency, percentages), gross margin, regression analysis and the Ricardian model. Data for computing gross margins and net revenue was taken from the on-farm trials. Gross margin was used on regression analysis and the net revenue was used on the Ricardian model. The results of the regression analysis indicated that land size, farmer’s experience to farming, level of education, use of fertiliser, use of irrigation and the yield obtained were significant and have a positive relationship with farmers gross margin. The results of the Ricardian model indicated that climate change affects both farming systems, but farmers that are producing under dryland are the most affected farmers because they rely more on climate variables especially rainfall for their production. So a change in climate variables affects maize farmers’ productivity and thus affecting farmers’ gross margin and net revenue. The study recommends that the farmers must use irrigation in order to support maize production even in the absence of rainfall. Farmers must also adapt to the short growing season so that they will be able to produce even in the presence of climate change.
Antibacterial Activity of Metallic Nanoparticles against MultidrugResistant Pathogens Isolated from Environmental Samples: Nanoparticles/Antibiotic Combination Therapy and Cytotoxicity Study
(American Chemical Society, 2022-09-26) Adeniji, Oluwaseun Ola ; Ojemaye, Mike Onyewelehi ; Okoh, Anthony Ifeanyi
Multidrug-resistant organisms have increased the prevalence of infectious diseases and have become the leading source of death globally. The adverse effects associated with conventional antibiotics cannot be underestimated, and as a result, the quest for antibacterial agents has received great attention over the years. Therefore, the current research was designed to synthesize and examine the antibacterial properties of two metallic nanoparticles, silver nanoparticles (AgNPs) and zinc oxide nanoparticles (ZnONPs), as well as their antibiotic combination therapy against multidrug-resistant bacteria. AgNPs and ZnONPs were synthesized by the coprecipitation method and characterized. Thereafter, their antibacterial activity against multidrug-resistant bacteria was investigated using the microdilution technique. Subsequently, the interactions between the synthesized nanoparticles and antibiotics were evaluated by checkerboard assay. Time-kill assays were carried out to assess bacteriostatic or bactericidal effects, and the cytotoxicity study was carried out by MTT assay. The SEM analysis of AgNPs and ZnONPs were spherical with an average size of 21.03 and 43.37 nm, respectively. FTIR analysis showed the characteristics of the metal−oxygen vibrational band for both materials around 450 cm−1 , which indicated the successful synthesis of these antibacterial agents. The EDX characterization revealed Zn and O with 77.89% and 18.24% abundance in ZnONPs and Ag with 95.65% abundance in AgNPs. UV−vis absorption spectra of AgNPs was obtained around 400 nm. ZnONPs showed a moderate antibacterial effect against Enterococcus species with a MIC range of 2.5−5 mg/mL, while AgNPs demonstrated a strong antibacterial effect against the tested bacterial strains with a MIC range of 0.078−0.039 mg/mL. The ZnONPs were found to be cytotoxic against Vero cell lines at the tested concentrations, whereas AgNPs had no cytotoxic effect at lower concentrations. Their combination activities showed synergetic and additive effects. These findings revealed that these synthesized materials could serve as alternate antibacterial agents against multidrug-resistant Acinetobacter baumanni and Enterococcus species.
Assessing the impact of primary agricultural co-operative membership on smallholder farm performance (crops) in Mnquma Local Municipality of the Eastern Cape Province
(University of Fort Hare, 2014) Mzuyanda, Christian
When the issue of economic growth and development of a developing country is raised, one has to take into account the performance of the smallholder farmers, especially where the agricultural sector is an important employer of labour and source of livelihoods. Reducing the challenges they are facing and utilizing their potentials can help to accelerate the transformation of the agricultural sector and economic development of the country as a whole. Agricultural cooperatives are ideal means for self-reliance, higher productivity and promotion of agricultural development. Therefore, the major concern of this study is assessing the impact of cooperative membership on farm performance in Mnquma Local Municipality. In order to address these issues a structured questionnaire was used to interview 100 farmers. Farmers were divided into two groups, one group consisting of fifty members of agricultural cooperatives and the other fifty non-members of cooperatives; all these farmers were randomly selected from Ngqamakhwe, Butterworth and Centane in Mnquma. The study investigated and profiled the socio-economic situation of the farmers. It also undertook a comparison of the members and non-members of the co-operatives in terms of their production and marketing activities. To analyze the data, descriptive and inferential statistics were used to explain some measures of central tendency and dispersion as well as test the hypothesis that there is a difference in performance between members and non-members of cooperatives. In addition, a simple linear regression model was used to assess the impact of cooperative membership on farm performance. To avoid selection bias that arises from the use of the simple linear regression model, the propensity score matching was also used to test the effect of different treatments on the sample. The expected results were that members of cooperatives perform better in terms of farm revenues, incomes and value of inputs used than non-members. In addition, the expectation was that members of cooperatives have larger plots of land, high crop yields hence generating high revenues per unit sold. The results from the field survey indicated that cooperative membership is positively related to performance (including revenue, farm income and value of inputs used), although some development programmes are needed to enhance performance of these farmers. Members of cooperatives produce and sell large quantities of output compared to non-members. This could be attributed to the fact that cooperative members receive farm inputs and extension support. Because of the frequent visits by extension officers, members of cooperatives have high access to market information. The results further confirm the hypothesis that membership in a cooperative has a positive impact on farm performance. The results from the first regression model indicated that membership in a cooperative has a positive and significant influence (p=0.004) on farm income, and (p=0.124) on revenue. The second regression model indicated that membership of cooperatives has a positive and significant influence of (p=0.007) on farm income, (p=0.138) on revenue. With regards to value of inputs, membership was found not significant at 1%, 5% and 10% levels. The age of household head, number of years spent in school, land size, access to information, type of market and ward in which these farmers are situated significantly influence farm performance at 1%, 5%, and 10% levels. Propensity score matching also confirms this hypothesis that membership was significant in respect to farm income (p=0.006) although not necessarily so in respect to revenue (p=0.088). While the study confirms the positive contribution of cooperatives, it is clear that more needs to be done to achieve greater inclusivity and make livelihoods improvements more sustainable. This calls for interventions from government and NGOs to motivate individual farmers to join cooperatives and operate within the framework of organized groups. The support could be provided in terms of credit to farmers, extension services and infrastructure development to serve smallholder farmers. In terms of further research, the study suggests that research on cooperative membership impact on farm performance in all forms of cooperative would yield immense insights for policy. Also, the present study was limited to only one municipality and it is necessary to conduct similar studies in other parts of
Assessing the socio-economic factors influencing wool production in Kolomana villages of Eastern Cape, South Africa
(University of Fort Hare, 2013-01) Mahashi, Mthetho
Despite considerable investment by government and non-governmental organizations (NGO) to support wool production among farmers in parts of the Eastern Cape Province, the sub-sector continues to feature low production and productivity while the small scale farmers continue to wallow in poverty. There is therefore genuine interest to gain deeper understanding about the reasons for this situation and identify elements for a strategy to remedy the situation. Sheep were found to be the most important livestock species and mainly used for wool production to raise incomes.
Assessing the Venturing of Rural and Peri-Urban Youth into Micro- and Small-Sized Agricultural Enterprises in the Eastern Cape Province, South Africa
(MDPI, 2023-10-31) Thibane, Zintle; Mdoda, Lelethu; Gidi, Lungile; Mayekiso, Anele
This study aimed to empirically assess the venturing by rural and peri-urban youth into micro- and small-sized agricultural enterprises in the Eastern Cape Province, South Africa. The aim of the study was achieved by focusing on the following specific objectives: analyzing youth involvement in agricultural enterprises; estimating the factors that influence youth participation in micro- and small-sized agricultural enterprises; and identifying constraints and opportunities for youth involvement in micro- and small-sized agricultural enterprises in the Eastern Cape Province. The study used multi-stage and snowballing sampling to select the respondents, and cross-sectional primary data were collected from 120 youths who ventured into micro- and small-sized agricultural enterprises. Only 70 youths from the sample participated in agricultural enterprises. The study was geared toward proposing a funding framework aligned with the characteristics of small- and micro-sized enterprises (SMEs) which can be used by both development finance institutions (DFIs) and commercial banks to assess applications for funding SMEs.
Assessment of socio-economic characteristics that determine farmers’ access to agricultural extension services in Eastern Cape, South Africa
(South African Journal of Agricultural Extension, 2021-04-26) Loki, O; Aliber, M ; Sikwela, M. M
The study reported on in this paper investigated smallholder farmers’ access to extension services. The study sought to distinguish the varying degrees of access to services of smallholder farmers engaged in different production systems, that is, home gardening, field cropping, and livestock production. The study was conducted in Raymond Mhlaba Local Municipalityin the Eastern Cape, specifically in two communities, namely Ngcabasa and Phathikhala villages. Research activities included a survey of 100 farmers as well asfocus group discussions. Employing logistic regression analysis, the study aimedto understand what influences whether or not a smallholder farmer accesses extension. The study also used various types of comparative statistics (T-test) to assess the implications of access to extension support, for instance for production and farm income. The main findings of the study were that 68% of the farming households interviewed in Ngcabasa and 71% of those in Phathikhala had access to extension services. Farmers who had access to extension had more farm income in both enterprises compared to those who had no access to extension services. From the regression analysis, farmers who were more likely to receive extension support appeared to be those who wereolder, those with less education, and those farming with livestock
Assessment of the performance of smallholder irrigated sugarcane farming in Maphumulo Municipality of KwaZulu-Natal Province
(University of Fort Hare, 2014) Mdletshe, Sifiso Themba Clement
Kwa-Zulu Natal (KZN) is mainly composed of small-scale farmers with low production capacity and knowledge (ISRADS, 2004). The general problem is the performance of smallholder irrigation schemes, issues that cause low productivity; whereas the cost of purchasing machinery is too high. In the rural areas the majority of the people are unemployed due to different reasons such as lack of employment opportunities available to them, lack of skill, and low level of education and mostly they are inexperienced. This study identifies theperformance of irrigation projects amongst smallholder sugarcane farmers in KwaZulu Natal in order to uplift the livelihood of smallholder sugarcane production as well as its sustainability.This was done on the basis of demographics, historical background and agricultural potential. This dissertation will discusses all approaches used to conduct the study. The dissertation also describes the analytical framework used in this study, namely: The research design, sampling, sample size, data, data collection procedures, model description and the specific analyses carried out to address the study objectives. The results of net values of irrigated and non-irrigated lands, the irrigating households indicated13% of sugar cane production per hector more than non-irrigators. It is clearly indicated that water/ irrigation can contribute on maximizing sugarcane yield and promotes sustainability. Improving the technology from small scale growers’ point of view, extension officers from different areas that produce sugarcane should be scheduled to attend Refresher Courses at SASRI to train them on different aspect of irrigation management and sugarcane production. When there is newly established technology, such as invention of a new variety of sugarcane that is resistant to drought and diseases. It would be more essential for agricultural development to encourage government investment on more irrigation schemes facilities.
Barriers and incentives to potential adoption of biofuel crops by smallholder farmers in selected areas in the Chris Hani and O.R Tambo District Municipalities, South Africa.
(University of Fort Hare, 2014) Cheteni, Priviledge; Mushunje,V.
Since the launch of the Biofuels Industrial Strategy in 2007 by the South African government, only a few smallholder farmers have adopted biofuels for production. The government hopes to stimulate economic development and alleviate poverty by targeting areas that were previously neglected for agriculture by the apartheid government. However, there still appears to be a lack of a clear and comprehensive policy framework for the development of a South African biofuel industry, because the proposed initiatives have not been implemented to date. There are also concerns among stakeholders that government policy is taking too long to formulate, compounding existing uncertainty in the industry. This study therefore aims to identify barriers and incentives that influence the potential adoption of biofuel crops in selected areas in the Eastern Cape Province, South Africa. The study utilised a semi-structured questionnaire to record responses from 129 smallholder farmers that were identified through a snowballing sampling technique. Descriptive statistical analysis and a Heckman two-step model were applied to analyse the data. Analysis was done using SPSS 21 and EViews 8. Results obtained showed that the variables: arable land, incentives offered, challenges faced, labour source and farm experience were statistical significant at 5 or 10 percent p value to awareness of farmers to biofuel crops. Adoption of biofuel crops was statistically related to gender, qualification, membership to association and household size. The study recommends that the Biofuels Industrial Strategy Policy be revisited in order to have a mechanism of including smallholder farmers that it aims to empower with employment and improvement in their livelihoods. The government can help smallholder farmers by addressing the challenges they face in improving their output. Furthermore, it recommends that a national study on barriers and incentives that influence the adoption of biofuel crops be carried out in order to identify other factors that may hinder the Biofuels Strategy Policy aims in empowering the disadvantaged farmers.
Classification and Diagenetic Characteristics of the Cretaceous Sandstones in the Southern Bredasdorp Basin, Offshore South Africa
(Wiley, 2021-10-30) BAIYEGUNHI, Temitope Love ; LIU, Kuiwu ; GWAVAVA, Oswald ; BAIYEGUNHI, Christopher
A systematic petrographic and geochemical studies of 92 representative sandstone samples from exploration wells E-AH1, E-AJ1, E-BA1, E-BB1 and E-D3 in the southern part of the Bredasdorp Basin was undertaken to classify the sandstones as well as unravel the main diagenetic processes and their time relations. Petrographic study shows that the sandstones are largely subarkosic arenite and arkosic litharenite, which have underwent series of diagenetic processes as a result burial, rifting and subsequent uplift. The main diagenetic processes that have affected the reservoir properties of the sandstones are cementation by authigenic clay, carbonate and silica, growth of authigenic glauconite, dissolution of minerals and load compaction. The major diagenetic processes reducing the porosity are calcite cementation in the subarkosic arenite, and compaction and quartz cementation in arkosic litharenite. On the other hand, the formation of secondary porosity due to the partial to complete dissolution of early calcite cement, feldspars and minor grain fracturing has improved the reservoir property of the sandstone to some extent. The clay minerals in the sandstones commonly acts as pore choking cement, which reduces porosity. In general, there is no particular diagenetic process that exclusively controls the type or form of porosity evolution in the sandstones.
Consumer perceptions and values on beef quality: Implications on beef markets.
(University of Fort Hare, 2014) Mabhera, Sunungukai
Beef constitutes an important part of many consumers’ diets. Beef is the most consumed red meat in South Africa. Consumer perceptions can affect the whole supply or value chain of beef. Recently there has been increased interest in food safety; greater concern for environmental and animal welfare issues, increased importance of eating quality and healthy food as well as the greater role of food services. The demand for beef is no longer limited to economic factors alone but to non-economic factors as well. Consumers of beef in Alice have become more concerned about meat-borne risks and personal health. This research prioritized the exploration of the beef consumers’ (i) self-perception (ii) price perception (iii) benefit perception [in the form of – (a) value perception and (b) quality perception]. The study was conducted in the Eastern Cape Province specifically in Alice town and the surrounding rural areas (Ntselamanzi, Gaga, Hillcrest, Gqumashe, and Dyamala) of the Nkonkobe Municipality. Anyone who admitted to eating beef and at the point of data collection bought beef for their own consumption or family consumption was deemed as a unit of analysis. Non – probabilistic sampling techniques which included accidental and random sampling were used to collect data from 100 interviewees. A semi structured questionnaire was used to analyse the perceptions and attitudes of beef consumers. The respondents were asked to indicate their agreement or disagreement with 47 statements or items presented on either five alternatives in a Likert scale scored from 1 (strongly disagree) to 5 (strongly agree) or a six Likert scale ranging from 1 (very low) through 5 (very high) to 6 (I do not know).The data was analysed using SPSS. It was discovered that beef consumers did not consider either intrinsic or extrinsic cues in isolation when purchasing beef but rather all characteristics contribute to the final perception. The Alice consumer market is heterogeneous and consists of different races with different cultures and market segments with varying needs and preferences. The results showed that five factors were extracted from forty seven items Factor 1: Information reliance and quality indication; Factor 2: convenience; Factor 3: Traceability and animal Welfare; Factor 4: Health and safety Conscious and Factor 5: Price and Branding. Furthermore, four main consumer segments emerged as - Segment 1: Informed buyers; Segment 2: Elite buyers; Segment 3: Health & safety conscious buyers and Segment 4: Apathetic buyers. The cluster analysis shows that quality is a subjective concept that is informed by a consumer’s personal taste and preferences. Taste and preferences inform the consumer’s effective demand which in retrospect is informed by the consumer’s socioeconomic status.
The design, implementation and effects of the Nguni project in the Eastern Cape Province of South Africa
(University of Fort Hare, 2009) Somoro, Lovett Mophethe
The main objective of the study was to examine the design, implementation and effects of the Nguni project in the Eastern Cape Province of South Africa. This was seen as an important exercise considering that most agricultural development initiatives in rural communities fail or their success rate has been low. Agricultural development initiatives should provide economic and social benefits, failing which; most well-intentioned initiatives result in adverse effects to the society. Therefore, an examination of the design, implementation and effects of the Nguni project would go a long way in helping to highlight and rectify pit-falls in similar future intended projects. A sample survey was conducted in Amatole, OR Tambo, Chris Hani, and Alfred Nzo District Municipalities, using structured questionnaires, supplemented by observation. The questionnaire covered demographic, management and personal aspects in order to elicit respondents‟ values, aspirations, experiences and perceived constraints. The data were analysed using descriptive and quantitative statistics. The findings indicate that the project was well designed and implemented, though its performance suffered from some problems that can be corrected through proper involvement of all the institutions involved.
Determinants of exchange rate volatility in South Africa
(University of Fort Hare, 2015) Dewing, Desiree
The rand is observed to have experienced volatility in recent times, which was particularly pronounced during times of crises such as the East Asian Crisis of 1998 and the global financial crisis of 2008. The purpose of this study is to identify key macroeconomic variables that determine exchange rate volatility in South Africa, and to also determine the contribution of each of these variables to volatility. The study makes use of quarterly data from 1994 to 2014. Volatility is measured by means of a generalized autoregressive conditional heteroscedasticity approach. Estimation techniques employed include the Johansen Co-integration and vector error correction model. Impulse response and variance decomposition analysis revealed that interest rate differentials account for most of the variation in exchange rate volatility (36 percent), followed by inflation rate differentials (31 percent), economic growth (3.5 percent), trade openness (0.45 percent), money supply (0.25 percent) and government spending (0.03 percent). Interest rate differentials and inflation rate differentials thus account for 67 percent of the 71 percent variation in exchange rate volatility in South Africa, with trade openness, money supply and government spending all being of low levels of significance. The large impact that monetary variables have on exchange rate volatility implies that policymakers should maintain sound monetary policies, ensuring that large unwarranted increases in interest rates do not occur in the bid to control inflation.
Determinants of rural households’ diversification of livelihood strategies: a case of Intsika Yethu farmers of the Eastern Cape Province, South Africa
(2014) Munhenga, Daniel
Despite the continuing perceived economic centrality of agriculture in Intsika Yethu local municipality, rural households engage and pursue diverse non-farm livelihood activities to cope with diverse challenges and risks such as drought. This study assessed the importance of existing livelihood strategies adopted by the different rural households in Intsika Yethu; the link between households’ ownership and access to different ‘assets’; factors determining households’ ability to adopt certain livelihood strategies in the area. A survey of 120 households in six administrative areas and informal discussions with key informants were used to collect demographic data, data on socio-economic activities and factors determining the choice of livelihood strategies of the households in Intsika Yethu. The research findings indicated that only about 10% of the interviewed households relied solely on on-farm livelihood strategy only. Credit, remittances, market distance, affiliating to cooperatives, education and household size have a potential of influencing households to shift from on-farm livelihood strategy to other livelihood strategies. The government may need to promote programs and awareness on how households can diversify their livelihood strategies as a way of coping with economic constraints in the area.
