Characterisation of a scum in sport drink and determination of the effects of preservation factors on its development.

Mapompo, Odwa Mcebisi. January 2013 (has links)
The development of a scum in a commercial sports drink is of concern because the product would be of poor quality, which may result in financial losses due to consumer rejection of the product and hence a decrease in the firm’s market share. The scum could be harmful to health and as such the firm could be litigated. Several factors, including microbial proliferation, may be the cause of the development of a scum in sports drink, but the actual cause seems not to have been established. The aim of this study was to characterise the scum in sports drink and determine the effects of preservation factors (pasteurisation, chemical preservatives and refrigeration) on its development. Samples of the sports drink were taken at different stages of processing to determine the effect of preservatives, pasteurisation and storage temperature on scum development. Some samples were kept at room temperature (approx. 25°C) and others were kept in the refrigerator (approx. 4ºC) during the study. A total of 150 samples were analysed over a period of four months. The structural characteristics of the scum that developed in the sports drink were determined by scanning electron microscopy (SEM) and elemental analysis. The sports drink samples were analysed for their microbial load and microbial types. Consumer acceptability of pasteurised and non-pasteurised drink was compared by conducting sensory evaluation using a consumer panel of 60 panellists. Customer complaints recorded by the sports drink manufacture that were due to scum development in the drink were also reviewed to establish the impact of scum development on consumer acceptability of the drink. The results of the study indicated that scum development was due to microbial contamination of the drink. The causative organism of the scum was identified as Acinetobacter baumanii. Acinetobacter baumanii is a gram negative non-spore forming coccobacilli and does not ferment sucrose. Acinetobacter baumanii forms the scum in sports drink as a means of protection from environmental stresses. The scum was found to be a compound of C, Si and O. The non-pasteurised samples were slightly more acceptable to consumers compared to the pasteurised samples. The consumer acceptability of pasteurised drink samples was negatively affected by the loss of aroma and flavour during pasteurisation. The preservation factors (chemical preservatives, pasteurisation and refrigeration) had no effect on scum development. To prevent post pasteurisation contamination, it is recommended that the pasteurisation process be done at the filling stage instead of at the holding stage. The frequency of changing rubbers and gaskets on the filling line should be at least every two months. The drink is pasteurised at 90ºC for 20 seconds, this needs to be reduced to a level where it will not have an influence on the loss of taste and aroma of the pasteurised drink, but without reducing the effectiveness of pasteurisation. / Thesis (M.Sc.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

The contribution of dairy credit guarantee scheme to household food security among the beneficiaries in Swaziland.

Nhleko, Nicholus Paul. January 2011 (has links)
More than 60% of the dairy products consumed in Swaziland are imported from South Africa. The Swaziland Dairy Board had established the dairy credit guarantee scheme with Swaziland Finance Development Cooperation to improve local dairy production and boost the livelihoods of smallholder dairy farmers. Unfortunately, the scheme was terminated without its effectiveness being evaluated. Therefore, the study set out to investigate the contribution of the dairy credit guarantee scheme to household food security. A total of 30 beneficiary households participated in the study. The data were collected through a structured questionnaire and analysed using the Statistical Package for Social Sciences (SPSS version 18.0). The households were compared in terms of the mean number of cows, milk production and volume of sales using the Duncan Multiple Range Test (DMRT). The dairy scheme was open to all qualifying smallholder dairy farmers, but most (86.7%) beneficiaries were male. The beneficiary households owned, on average, between one and eight cows between 2006 and 2009, and produced 188079 litres of milk on average per year. The highest income generated from milk sales was R74137.00 per year between 2006 and 2009. The lowest income from milk sales was R1020.00, from a household with the lowest number of dairy cows on average per year between 2006 and 2009. Beneficiaries reported that the increase in income enabled them to accumulate agricultural assets, increased food purchases and the diversification of livelihoods. Over 56.7% of the households were able to diversify their livelihoods by engaging in other income-generating projects such as poultry and pig production, horticulture, selling groceries and block (brick) making. With improved income especially milking households were able to increase food supply and this is indicated by their higher average Food Consumption Scores (75.58) than non-milking households (59.65). However, all the average Food Consumption Scores were above 42 which is a threshold level for acceptable nutrient intake, dietary diversity and this implies that the dairy production scheme led to improved dietary intake. In conclusion, the dairy credit scheme has the potential to improve local milk production and household food security. It is, therefore, recommended that the dairy scheme be revived, with better accessibility. The establishment of dairy development policy should be considered, in order to create a favourable environment for dairying and the promotion of cooperation among dairy development partners. This cooperation would help to avoid duplication of efforts among development partners and create a platform for interaction, sharing of information and exchange of ideas. / Thesis (M.Sc.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2011.

Investigation of selected hygiene parameters of uMbumbulu small-scale farmers' organic produce (leafy salad vegetables) and subsequent identification of factors affecting farmer practices and food security.

Mdluli, Fezile. January 2013 (has links)
The study aimed to investigate the hygiene quality of fresh agricultural produce, irrigation water and compost from four cooperatives (Jabulani, Nungwane, Senzakahle and Siyazenzela) supplying the uMbumbulu Agri-Hub Non-Governmental Organisation. In addition, the influence that socio-economic characteristics such as age, gender, level of education and training had on the uMbumbulu farmers’ hygienic practices was investigated. Questionnaires, key informant interviews and laboratory analysis were used to collect data. The most probable number (MPN) method, a microbiological technique, was used to quantify selected hygiene indicators (i.e. total and faecal coliforms including Escherichia coli) from compost, irrigation water and leafy vegetables (spinach and lettuce) during the months of October, November and December 2011. Microbiological analysis on lettuce and spinach produced by the four Agri-Hub cooperatives confirmed that these vegetables were safe to eat and unlikely to cause sickness. The irrigation water sources, vegetables and compost faecal coliform levels met national standards with faecal coliforms of <1 000 MPN/100ml for irrigation and<200 MPN/g for the leafy salad vegetables. Compost faecal coliform levels were <1000/g and E. coli levels of <30 MPN/g, these levels decreased over the 3 months. Descriptive statistics such as the Chi-Square test using IBM SPSS and a logistic regression was performed using the STATA 11 software. The sample consisted of 60% female and 40% males, most of which (73%) were above the age of 40. A total of 60% of respondents received income from farming activities, receiving revenues of between R150- R250 a week. The logistic regression indicated that farmers already receiving some income from farming activities and those that had received training on hygienic farming practices were likely to wash hands and equipment prior to entering the field compared to those who had not. These variables influenced the hygienic practices with a probability of 26% and 32% respectively at 5% significance level. The logistic regression also showed that respondents with primary or no formal education were less likely to wash hands and equipment prior to entering the field compared to those who had a secondary level education. This unlikelihood had a probability of 35% for primary education and 43% for farmers with no formal education at significance levels of 5% and 10% respectively. This study indicates how training, education and farming experience are important and effective tools in implementing good hygienic practices in small-scale farming. The study’s main recommendations are that policies encourage farmer awareness on their responsibility of producing vegetables that are of good hygienic quality, especially if such produce is to reach the market. Furthermore policies should advocate for small-scale farmer training. This training should not be limited to subsistence farming but should also aim at preparing farmers towards accessing produce markets. Farmer training in hygienic practices should aid farmers to meet the stringent market standards allowing for better access, the regular income from such activities support farming as a livelihood and bearer of food security. It must also be noted that farmers require support in attaining the various resources needed in order to successfully and continually supply markets. / Thesis (M.Sc.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

Do African country investment plans mitigate high food prices through improved household risk management? : a five-country comparative analysis.

Ngidi, Mjabuliseni Simon C. 10 April 2014 (has links)
Staple food prices rose sharply in 2007/2008, dropped slightly after July 2008, and rose again in 2010/2011. Since 2008, food prices have remained high, indicating a structural upward adjustment in food prices amidst excessive price volatility. The 2008 food price increases led to considerable media coverage and alarm among governments who implemented a variety of responses to protect their populations from food insecurity. At the start of the high food price crisis in May 2008, the African Union and New Partnership for Africa’s Development (AU/NEPAD) invited 16 African countries to a workshop in South Africa. The aim of the workshop was to assist selected African countries identify and formulate appropriate plans to mitigate food insecurity and manage rising food prices. This study set out to investigate whether the strategies implemented by national governments at the start of the crisis mitigated high food prices through improved risk management strategies in five African countries (Ethiopia, Kenya, Malawi, Rwanda and Uganda) and evaluated these strategies to see if they were included in the national agriculture and food security investment plans. To achieve this, the study set out to explore four sub-problems, namely: What was the impact of high food prices on populations in the five selected countries (Ethiopia, Kenya, Malawi, Rwanda and Uganda)? How did the five countries respond to the 2008 food price crisis with regard to providing for immediate needs and protecting vulnerable groups from food insecurity? How many early actions were included in country compacts and agriculture and food investment programmes? Do country investment plans include household risk management programmes that will protect vulnerable groups against high food prices in future? The involvement of the researcher in the AU/NEPAD workshop and his subsequent engagement with national government representatives provided a unique opportunity to analyse the iterative process of Country Investment Plan (CIP) development. This innovative and largely qualitative study integrated comparative, content and thematic analysis approaches, using the four elements of the Comprehensive Africa Agricultural Development Programme’s (CAADP) Framework for African Food Security (FAFS) to analyse the national plans. The study drew on available data from a wide variety of national, regional and international documents. Additional data were collected through a survey questionnaire completed by CAADP country focal persons. Data sourced from documents included Food Price Indices, country policy responses to high food prices, poverty and malnutrition indicators and the types of risk management strategies designed under CAADP. The study found that food prices increased across all five countries between 2007 and 2008, although the effects of the increases varied, being influenced by, among other factors, the proportion of national stocks purchased on the international market (i.e. net importers of staple crops), the availability of substitute staples on the domestic market and the magnitude of the difference between international and domestic market prices. The 2008 food price increases forced populations to spend a higher proportion of their income on food and eroded their purchasing power, impacting on the food security of these populations. Poor people adopted eroding consumption strategies that increased food insecurity. The impact of the high food prices on populations was determined by whether they were net food buyers or producers, the mix of staple commodities in their food basket and the proportion of income spent on food. As poor net food importing countries, imported staple foods became too costly, except in Uganda - a net exporter of food staples consumed in the surrounding countries. High food prices also provoked social unrest in Ethiopia and exacerbated political and economic instability in Kenya. Countries’ early responses to the food price crisis were varied and included responses that can be classified into three main categories, namely: Trade-oriented responses protected domestic stocks, reduced tariffs, restricted exports to reduce prices for consumers or increased domestic supply Consumer-oriented responses provided direct support to consumers and vulnerable groups in the form of, among others, food subsidies, social safety nets, tax reductions and price controls Producer-oriented responses provided incentives for farmers to increase production - using measures such as input subsidies and producer price support. Most responses were aimed at managing prices, suggesting that governments tried to protect citizens from price increases and buffer consumption reduction. Safety net programmes mitigated risks through the provision of food for immediate consumption. As a result, malnutrition levels unexpectedly decreased or remained static in these five countries, despite expectations and media claims that the number of hungry people would increase significantly. The early actions from the food price workshop plans were generally systematically translated into long-term programmes in the Compacts and Country Investment Plans. In Ethiopia, seven of eight early action plans were translated into the CIP, Kenya included three of eight, Malawi’s CIP included four of ten, and Rwanda included six of its ten early actions in their CIP programme, while Uganda included only six of thirteen early actions in their CIP. The study found that CIPs included risk management strategies, but these focused predominantly on improving early warning systems and crisis prevention. The risk management options largely included options for improving crisis prevention, followed by improving emergency responses and strengthening risk management policies and institutions. Only Kenya’s CIP included more risk management options for improving emergency responses – four of six risk management programmes. Despite expectations that programmes developed under CAADP FAFS would include all FAFS elements, CIPs lacked programmes to improve dietary quality. Only Rwanda’s CIP included nutrition programmes - three of six programmes in their CIP. The study concluded that while the proposed risk management strategies could mitigate risks associated with high food prices and offer some buffer for populations from food insecurity, the programmes are not comprehensive. The plans were generally weak regarding improving dietary quality through diversification of food consumption and production. Although the CIPs included risk management strategies, these strategies would not address risks in a comprehensive manner. More effective and coherent actions are still required to help the most food insecure populations cope with increasing high food prices and future price shocks; help developing country farmers respond to the opportunities offered by the rising demand for their products; and bring more stability in prices. The early food price response workshop seems to have influenced the development of programmes in the CAADP compact and CIPs, despite the fact that the workshop did not intend to assist countries with the development of comprehensive national investment plans. The large funding gaps in the CIPs constrain implementation of essential mitigation and development strategies and could leave countries vulnerable to the negative impacts of higher prices for consumers and threaten future household food security. The study recommends that countries invest in agriculture-led growth to boost domestic production and strengthen institutional capacities regarding national food stock reserves to reduce their dependency on imports and ensure food insecurity. National monitoring and evaluation systems need to be strengthened to evaluate and monitor the implementation of CIPs and to warn about future high food prices. Empirical estimation of the impact of price increases on households across all CAADP countries is needed to understand and monitor the impact of price changes and interventions. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2012.

Can livelihood approaches adequately evaluate the determinants of food insecurity to inform interventions in Kenya?

Mutunga, Nancy Muthoni. January 2012 (has links)
Food insecurity has remained pervasive for most Kenyan livelihoods despite the implementation of substantive interventions by the government and its development partners, since it gained independence in 1963. The inability to isolate distinct determinants of food insecurity for each livelihood group has led to interventions and solutions that have entrenched food insecurity rather than mitigate it. The key impediment to a livelihood-level analysis of food insecurity is the use of data and information collected at district-level administrative units, coupled with the absence of a robust analytical methodology. This study set out to identify determinants of food insecurity for three distinct livelihood groups in Kenya, namely the pastoral, agro-pastoral and marginal agricultural groups. The study also sought to empirically evaluate incremental impacts of identified determinants of food insecurity for each group. The outcomes were intended to inform the selection of particular indicators in order to target, monitor and identify important inter-relationships between variables for each livelihood group. Few studies have applied heterogeneous ordered logit regressions to livelihood-level data to evaluate food security determinants among livelihood groups and a comprehensive livelihood analysis of the determinants of food insecurity has not yet been undertaken in Kenya. Yet, Kenyan livelihoods are highly diverse, and livelihood characteristics transcend administrative boundaries. This study used a heterogeneous ordered logit to model determinants of food security in Kenya. The variables were: conflict, HIV/AIDS, rainfall, flooding, proximity to markets, migration patterns, food consumption sources, income contribution sources and own farm production. Results of significance tests and residual variability from the ordered logistic regression led to the identification of important determinants of food insecurity in each of the three livelihoods. The degree to which each of the variables was influential in accentuating food insecurity in each livelihood, was also evaluated. Determinants of food insecurity and their inter-relationships informed the selection of indicators for monitoring. Proximity to markets seemed to have a marked impact on food security in the pastoral, agropastoral and marginal agricultural livelihood groups. Conflict was influential in determining food insecurity, particularly for the pastoral and agro-pastoral livelihood groups. HIV/AIDS prevalence in the community was critical in determining food security status for the marginal agricultural and agro-pastoral livelihood groups. Rainfall was an important determinant of food insecurity in all the groups. Flooding had no significant impact on food insecurity. The results showed that an increase in the number of food sources improved food security in the pastoral, agro-pastoral and marginal agricultural livelihood groups. A diversity of income sources improved food security in the pastoral and agro-pastoral livelihood groups. The pastoral migration pattern seemed to have a substantial impact on food security especially in the pastoral and agro-pastoral livelihood groups. Own farm production was also influential in determining food security in both groups. The study outcome provides a basis for identification of important monitoring indicators including agro-climatic, trade and market processes, migration dynamics, income and food sources and the stability, settlement patterns, key livelihood and coping strategies in the three livelihood groups. The strong inter-relationships between variables suggest that multiple variables need to be monitored concurrently to address livelihood food insecurity in Kenya. The findings suggest that livelihood approaches are central to identifying determinants of food insecurity in Kenya. The outcomes of the study provide a basis for informing interventions intended to reverse food insecurity in Kenya for each distinct livelihood group. Further research could include an analysis of the impacts of seasonality, an in-depth analysis of the markets and their marked influence in affecting food security, and applications of similar methodologies to evaluate of the food insecurity of livelihood groups that were not covered in this study. Outcomes of this work are expected to provide a basis for formulating livelihood-specific interventions in Kenya. The results will provide a platform for further interrogation of important determinants of livelihood food insecurity by governments, researchers, and development partners. Aspects of the methodologies applied in this study can be replicated in adjacent countries with food security and livelihood characteristics similar to Kenya, such as Ethiopia and Somalia. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2012.

The impact of food aid on maize production in Swaziland.

Mabuza, Majola Lawrence. 17 August 2010 (has links)
The objective of the study was to provide empirical evidence on whether food aid leads to depressed domestic maize prices and reduced maize production in subsequent years in Swaziland. Similar impact studies have been carried out in a number of sub-Saharan African countries but no evidence is available for Swaziland. The lack of empirical evidence has often resulted in premature negative conclusions on the impact of food aid on Swaziland’s maize industry. The study used secondary national data from 1985 to 2006 to analyse the impact of food aid on maize producer prices and quantity of maize produced. Variables used in the analysis included quantity of cereal food aid; quantity of commercial maize imports; quantity of locally produced maize; official maize producer price; open market maize producer price; fertilizer price; fuel price; rainfall; and total area planted to maize. The impact of food aid was measured using the reduced form market equilibrium model that consisted of maize quantity and maize producer price functions estimated simultaneously using the above variables through the two-stage least square method (2SLS) method. Analytical results revealed that food aid to Swaziland does not lower prices of domestic maize and has no significant negative effect on the quantity of maize produced in subsequent seasons. This means that food aid received by Swaziland over the study years has been appropriately targeted and distributed to the food insecure households. If this were not so, the demand for food from commercial outlets would have been reduced, leading to an adverse impact on maize producer prices, and subsequent local maize production. Notwithstanding the above results, Swaziland should still commit resources towards reducing the national food gap. This calls for increased investment in rural irrigation development, improved farmer institutional support services, and the implementation of pro-poor development programs aimed at improving individual household income to reduce the need for food aid, improve food self-sufficiency and vulnerability to food security. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2007.

The impact of policy on perceived livelihood vulnerability : the case of Cato Manor.

Caister, Karen. January 2005 (has links)
This dissertation describes the outcome of a sustainable livelihoods approach to assess the livelihood vulnerability of community structures in Cato Manor (an urban renewal project of Durban City, KwaZulu-Natal). The sustainable livelihoods approach used looked at the specifics of the nature of assets wealth, and how the poor made a living. The vulnerability of poor households and communities depends on the way the poor have combined available assets and capabilities within a particular context to achieve short and long term priorities. Amongst other contextual issues of developing countries, structural adjustment has affected urban survival strategies. This study explored whether the impact of post-apartheid policy had reduced livelihood vulnerability for members of ten community structures in Cato Manor (CM). The investigation was broken down into two sub-problems. Sub-problem one was to establish what impact post-apartheid policy outcomes had on livelihood strategies in Cato Manor. Sub-problem two set out to ascertain whether the livelihood strategies described by participants in Cato Manor reflect reduced livelihood vulnerability. A unique feature of this study was an agreement between community based facilitators from Cato Manor (Cato Manor Development Association (CMDA) team) and the researcher for the development of two research agendas. The CMDA team, comprised of five community facilitators from the Seliyabuya Housing Co-operative and a Cato Manor Development Association consultant, conducted sustainable livelihoods analyses as the first stage of strategic planning for community structures. A secondary case study analysis of livelihood vulnerabilities was carried out by the researcher using the secondary data from these sustainable livelihoods analyses. Ten of the thirty five community structures (29%) identified by the CMDA team as possible participants elected to participate in the sustainable livelihoods analyses. Members of these structures formed ten groups based on the focus of their structure goals. Each focus group conducted a sustainable livelihoods analysis that reflected the assets, strategies for livelihoods and constraints that affected structures' priorities. Each participant was also asked to complete a household survey questionnaire providing demographic data for the case study. The findings of this study showed a tension between government's structural adjustment goals and the realities of actual delivery. The development goals provided for an urban space with the physical structures for livelihood security and sustainability. The study identified that development has provided a significant accumulation of physical assets through infrastructure delivery. However, perceptions of the participants indicated that development has not provided sufficient economic opportunities; adequate housing; or educational, social and recreational facilities for desired livelihood outcomes. In addition, participants believed manufacturing and business growth dependent on the successful marketing of products was in direct conflict with the actual physical restrictions of the topography, housing density goals and conceptualisation of the economic opportunities existing in Cato Manor. Participants relied on survivalist strategies of micro-enterprises (such as informal trading), and reliance on collective community support as available rational options for survival. Livelihood vulnerabilities indicated by the study were: overcrowding of homes, both in formal and informal areas; national economic trends resulting in job shedding by the formal sectors; and the slow beginnings of local economic development. In addition, there would be the threat to this community of the unknown impact of or capacity for the eThekweni Municipality's continuing the development required in Cato Manor after closure of the Cato Manor Development Association; and the impact of HIV/AIDS on the human, economic and social capital. This study showed increasing vulnerability for households and community structures represented by the sample in terms of physical capital, financial capital, and human capital. This vulnerability was particularly characterised at community level by the perception of increased dependency on cash amidst a corresponding reduction in available cash. It has been recommended that a creative institutional response, using clearly defined roles and responsibilities, collaborate with the community to define and make use of entry points for the transfer of skills and Local Economic Development support for the creation of employment opportunities. In addition, it was recommended that local government make full use of their knowledge of the livelihoods activities, and human capital in Cato Manor to facilitate the speedy delivery of appropriate infrastructure and economic support in a manner that supports the sustainability of municipal management as well as increases the livelihood options of the poor. To complement this study, further research requires an ongoing evaluation of the impact of local government and the community's responses; and an exploration of how democratic citizenship can be developed through the facilitation of grass-roots collective organisational strategies. / Thesis (M.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.

Food quality and safety of solar dried fruits and vegetables in the Butha-Buthe district, Lesotho.

Miricho, Esther W. January 2005 (has links)
This study investigated the quality and safety of solar dried fruits and vegetables produced by households in three locations in the Butha-Buthe district of Lesotho from November 2002 to March 2003. The aim of the study was to enhance year round availability of fruits and vegetables and reduce post-harvest losses, contributing to increased food availability and accessibility in the district. The study analysed the quality and safety of dried fruits and vegetables by assessing the processing techniques applied by the respondents during the production of dried fruits and vegetables, analysing the quality of dried fruits and vegetable samples produced by the study respondents using Appropriate Technology Section (ATS) solar driers, and by identifying the constraints that hamper the improvement of quality and safety of solar dried fruits and vegetables in the study area. Data was collected through focus group discussions, interviews, and laboratory food quality analysis of dried fruit and vegetable samples provided by the respondents. The dried fruits and vegetables produced by the respondents were of low quality due to poor processing techniques and unhygienic practices that increased chances of contamination and deterioration during processing and storage. Lack of processing skills and information, particularly on quality and safety standards, and weak extension support contributed to poor product. For the respondents to improve the quality and safety of dried fruits and vegetables, they need training and support with respect to quality and safety that includes training on the importance of food safety, best processing and storage practices and marketing of dried produce. / Thesis (M.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.

Do household coping strategies mitigate perceived household food insecurity among sample households in Dasse administrative area, Gash-Barka zone, Eritrea?

Beraki, Yergalem. January 2009 (has links)
This mini-dissertation sets out to examine the perceptions of farmers in the Dasse Administrative Area of Gash-Barka zone of the impact of agro-ecological, socioeconomic and infrastructural constraints on food insecurity, and the coping strategies employed by 101 sampled farm households in order to understand how these strategies increase vulnerability or mitigate the effect of food shortages. Agricultural productivity was low and average cereal production provided only 39 per cent of annual household requirements. Self-sufficiency in grain obtained from own production sustained households for only four months a year. In line with this, the study examined the impact of agro-ecological, socio-economic, and infrastructural constraints to the problem of food insecurity as perceived by the farmers. Farmers perceived drought, erratic rainfall, and weed infestations as major agro-ecological constraints that hindered self-sufficiency in food production. Shortage of draught animals and labour and lack of cash and off-farm income, were most conceived socio-economic constraints that affected production. Lack of farm credit, health problem (malaria), and inadequate farmers advisory service were most perceived infrastructural constraints that affected production and household food security. This shows that food security interventions need to be built around mitigating these perceived causes. The study also investigated coping strategies and their impact on increasing vulnerability or mitigating the effect of food shortages. The coping strategies applied by the studied households were largely consumption-based and non-erosive, indicating that households were relatively resilient to food security shocks. However, these strategies could be detrimental to the nutritional well being of household members, as they determined dietary intake. These coping strategies were particularly detrimental to household food security, as proper nutrition is critical for active and productive life. Thus, health and nutrition related interventions are highly required to address these problems. Food security interventions need to support livelihoods in ways that protect and buffer the natural resilience of households, providing direct assistance when erosive coping strategies are employed to ensure that households remain resilient to the fragile and variable situations in which they exist. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2009.

A case study of the impact of irrigation on household food security in two villages in Chingale, Malawi

January 2008 (has links)
This case study investigated the impact of irrigation on household food security at Ibu and Kalizinje villages in Chingale, Malawi. The aim of the study was to investigate whether irrigation improved household food security. The study was qualitative in nature. Fifty-eight farmers and three World Vision field staff participated in the study. Group discussions with participatory techniques and in-depth interviews were used to collect data. Data were analysed qualitatively using matrix/logical analysis. Irrigation improved irrigating farmers’ household food security through an increase in production and income levels. Irrigating farmers were better off in terms of crop production and income levels than non-irrigating farmers. Irrigating farmers planted irrigated maize two to three times a year, while non-irrigating farmers planted rain-fed maize only once a year. In terms of income levels, irrigating farmers produced more food than households required, and sold surpluses. Most irrigating farmers began cash cropping after the introduction of irrigation and also earned higher incomes, as irrigation enabled production of crops during lean periods and enabled them to sell surpluses at higher prices. Irrigation did not improve crop diversification. Non-irrigating farmers diversified crops more than irrigating farmers by planting groundnuts and sweet potatoes. Income from irrigating farmers did not increase dietary diversity and the acquisition of assets for irrigating farmers. Few farmers consumed a variety of foods and few acquired assets with the income derived from irrigation. Nevertheless, irrigation has the potential to smooth production cycles and provide food and income during seasons when food and income would be low. In addition, the study revealed the following as problems faced by farmers: constraining size of small diesel pumps, pump breakdown at Kalizinje, floods, pests and diseases, storage problems, lack of market places and poor roads, small land sizes, and expensive farm inputs. / Thesis (M.Sc..)-University of KwaZulu-Natal, Pietermaritzburg, 2008.
