Food insecurity in Southern Africa :causes and emerging response options from evidence at regional, provincial and local scales

Misselhorn, Alison Anne 19 February 2007 (has links)
Student Number : 0206926T - PhD thesis - School of Geography, Archaeology and Environmental Studies - Faculty of Science / The overarching objective of this thesis is to determine causes of food insecurity in southern Africa, and how it can best be addressed. This objective is addressed through a number of research questions and methods at three geographic scales: the regional, through a technique of meta-analysis which is used to synthesise 49 local-level household economy case studies; the provincial, through a Delphi panel of practitioner experience; and the local, using multiple research techniques, including participatory methods. An extremely diverse range of factors contributing to food-insecurity are found at all three scales, indicating that community- and household-specific dynamics give rise to forms of food insecurity. Two common processes, however, are argued to be common across all the casestudy communities in the regional-scale research. These are the closely related processes of cycles of intensifying vulnerability associated with livelihood ‘trade-offs’, and of communitylevel social capital changing into forms that undermine resilience to food insecurity - such as the decline in two-parent families. A further probing of social capital at the local level suggests that while social capital takes multiple forms, and further remains in many respects a problematic concept, it nevertheless provides a valuable lens through which powerful social dynamics might be examined in developing responses to food insecurity. Policy makers and change agents should carefully consider their role in building community social-capital that might enhance the ability of vulnerable communities to overcome livelihood constraints and adapt to the tremendous challenges posed by changing economic environments in southern Africa. Drawing on the research at all scales, a framework is provided that calls for a reconceptualisation of food-security interventions to focus on intervention processes, applicable at all scales and in all contexts across the region. The development of social capital, participation, co-ordination and learning interactions are explored as central elements in these processes. The framework asks for closer attention to both the appropriate mechanisms (such as policy) necessary to effect change, and the human dimensions that give these mechanisms agency. The findings of the thesis represent an additional shift in understanding food security to acknowledge that the value of a political economic interpretation of food security is limited independent of an understanding of the cross-scale social networks and relational interactions that ultimately configure and reconfigure it.

The role of land consolidation programme in household food security in Rwanda : a case study of household farmers of Gisenyi Village of Bugesera District.

Ntirenganya, Jules 28 August 2012 (has links)
The aim of this study is to investigate the outcomes of the Land Consolidation Programme (LCP) in household food productivity. The implementation of the 2004 Rwandan National Land Policy (which incorporates LCP) has been one of the Rwandan government strategic attempts to improve the livelihood of the Rwandans. In this study we look at some of the social-economic factorsbenefited by household farmers through the LCP since its implementation in 2007. In Sub-Saharan Africa many people depend on land for their livelihood and consequently, one of the obvious negative impacts has been the fragmentation of land. Historically the customary land management, in which inheritance is the major mode of land acquisition, has been the main way of allocating land in African societies. This communal tenure is viewed as unstable and leads to detrimental implications, in the form of mismanagement and overexploitation of the available land. The demographic pressure has also aggravated the issue of land scarcity and land fragmentation. The latter has consequences on agricultural productivity since it makes harder the efficient use of land. In this study the researcher explores the outcomes of the LCP in Rwanda as a type of land reform that aims at preventing fragmentation of land and enhancing the livelihood of household farmers. For achieving this objective, the study used a case study of household farmers from Gisenyi village of Bugesera district (in Rwanda) who are involved in the LCP since its implementation. Empirical data was obtained through in-depth interviews with 20 household farmers and 8 key informants. The emphasis in the study was put on investigating the state of household food productivity in Gisenyi. The study was guided by the property right theory and its basic conceptual assumption of enhancing the income through credit access. The findings of the study demonstrate that household farmers in Gisenyi village have benefited from the LCP. Household farmers confirmed that agricultural productivity has increased due to the new farming techniques brought by the programme. The study concludes that once the programme is properly and fully implemented, the LCP will highly enhance food self-sufficiency situation in Rwanda, improving also the livelihood of rural areas through other benefits such as infrastructure development.

African seed systems : the crises of food security and the rights of the farmer in Africa's globalising food regime

Taylor, Anthea Wedgwood January 2017 (has links)
A research report submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Arts (International Relations), 2017 / Through a close reading of the changes that have occurred within African agriculture using Food Regime Theory, this study will attempt to further understand the impact that has been felt by small-scale farmers who are a dominant feature of African agriculture. This paper will seek to understand the influence that the increased corporatization of agriculture through globalization has had on the small-scale farmer in Africa. As agriculture has become more and more corporatized and commodi:ied, it becomes important to consider the changes that have occurred for those actors within the industry and how these changes will impact them. This paper is attempting to do that through a close reading of the changes that have taken place within an integral part of the agricultural process: the seed. / GR2018

Implications of Socio-Ecological Changes for Inuvialuit Fishing Livelihoods and the Country Food System: The Role of Local and Traditional Knowledge

Heredia Vazquez, Iria 06 May 2019 (has links)
The Mackenzie River Delta is an ecologically rich freshwater environment in Canada’s Northwest Territories. It is vulnerable to multiple stressors such as climate change, resource development activities (oil and natural gas) and upstream-downstream linkages related to extraction activities in the southern part of the Mackenzie River watershed. Resultant socio-ecological impacts affect fishing livelihoods, which represent a significant component of the country food system and ways of life for Inuvialuit (Inuit of the Western Arctic), whose Settlement Area overlaps with the Delta. This thesis analyzes the implications of socio-ecological changes in the Mackenzie River Delta for Inuvialuit fishing livelihoods and the country food system, drawing from Local and Traditional Knowledge. In collaboration with the Fisheries Joint Management Committee in the Inuvialuit Settlement Region, the westernmost Inuit region in Canada, I undertook a participatory-qualitative research, while also drawing on relevant literature and complementary data. Using 28 semi-structured interviews about changes in the Mackenzie River Delta and the importance of fishing livelihoods, results indicated that fishing livelihoods are essential contributors to the Inuvialuit food system, as well as cultural practices surrounding fishing as an activity. Moreover, some results imply the importance of previously ignored species for food security, such as burbot and inconnu, which receive limited attention in other studies. Key findings also indicate that multiple environmental changes are occurring in the Delta, including lower water levels, increasing land erosion, decreasing fish populations, and changes in Delta-reliant wildlife populations (e.g. more beavers), warmer water temperatures, poorer fish quality (e.g. softer flesh, parasites), thinner ice, climate variability, and an escalating cost of living. These changes affect primarily fishing access and raise important concerns about the safety of fish consumption for human health. Ultimately, limited access and declining fish quality have a negative impact on food security, given the key role of fish in the country food system and the importance of socio-cultural dimensions such as fishing knowledge and skills, and sharing practices.

Towards food security with nutritional health : multi-scale approaches

Coghlan, Christopher January 2016 (has links)
This thesis addresses multi-scale approaches for improving food security with nutritional health. It argues that four key themes: scale, nutrition, trade, and governance are not given adequate attention in food security and nutrition studies. A multi-scale framework links the overriding thematic structure, bridges gaps, and enriches analysis. It facilitates a blended approach of analysis for food security and nutrition studies, public policy, and critical geography. Nutrition is at the centre of the inquiry and addresses the triple burden of malnutrition: hunger, micronutrient malnutrition, and obesity. Nutrition is hampered by an incomplete understanding of dietary diversity. Trade and governance are complimentary and cover dynamic commodity exchanges which might develop along with improved programme delivery. At the structural core of the work are four research papers which interact with established and emergent food security indicators and data for: the international system, nations, Indian states, and districts within Karnataka. Each paper uses specific methodological tools which are most compatible with the unique characteristics of the relevant scale. The first paper applies benchmarking and compares international FAO food security indictors with the EIU and other best practice sources to argue for improved data. In order to inform malnutrition beyond hunger, the second paper inputs FAOSTAT national food balance sheet data into a dietary food supply model of key nutritional food groups for medium activity individuals. The third paper employs Indiastat data to construct a food potential model representative of major components of the Indian food system, and compares it with production information for pulse varieties for inclusion in the NFSA. The fourth paper creates a nutritional HDI, compares it against the production of cereals and pulses, and considers weather conditions. Results illustrate that the FAO does not give proper attention to including governance indicators or capturing dietary diversity beyond hunger. Food balance sheet data shows that the majority of the world lacks the proper supply of key food groups to sustain a medium activity lifestyle, with fruit & vegetable deficits equally present in developed and developing nations. In India, states with the lowest food potential are located in the north and east of the country while some neighbouring states contain pulse production advantages. Further opportunities exist to use digital technologies to improve the administration of the programme. Similarly, northern districts of Karnataka require more direct NFSA intervention while the southern and coastal districts have the potential for increased production and trade of pulses. Implications for this study are centred on the development of future food security and nutritional health studies, policy, and administration. When possible, food security and nutrition studies can broaden their conclusions by expanding their base of indicators and data to take into account multi-disciplinary information. Possibilities for richer studies are evident through the development of more robust governance and dietary diversity indicators. These could focus on measurable programme results and take into account the impact of food groups and nutritional supply on various types of malnutrition. Multi-scale analysis might inspire cross-boundary policy formulation and assist in the development and trade of food system resources. The administration of food security programmes might improve with further study and the use of technology as a tool for delivery. This thesis clarifies how multi-scale approaches to food security and nutrition can be advanced through conceptual, methodological, and empirical work combining critical engagement, data analysis, and public policy.

An evaluation of the determinants of resilience to drought in Malawi

Chiroro, Canford January 2013 (has links)
Building resilient communities has emerged as a dominant agenda in the policy arena and in academia in the wake of recent disasters. However, there is a lack of clarity on the specific interventions required to build resilience. Current challenges associated with resilience include ambiguity, unclear measures, and problematized applicability. This thesis evaluates the determinants of resilience to drought in community food systems as a basis for contributing towards a more advanced understanding of resilience. A schematic model linking the key concepts associated with resilience was developed on the basis of literature review. This model was subsequently applied to a sample of 195 farm households, 16 community meetings and about 45 interviews with key informants across eight villages in Nsanje and Mzimba districts in Malawi interviewed between October 2010 and February 2011. Analysis at household level focused on exploring the causes of vulnerability, the role of livelihood assets and institutions in shaping coping and adaptation, and the implication of these to the meaning of resilience. The thesis concluded that vulnerability to food insecurity was produced by an interaction of slow and fast moving factors and processes, some of which were highly persistent. Access to livelihood assets and institutions increased short term coping and adaptive capacity but did not effectively predict resilience given unknowns regarding asset availability and liquidity over the long term. Different socio-economic groups associated different meanings with the concept of resilience, and in some cases, one group achieved ‘resilience’ at the expense of the larger community. In integrating vulnerability into resilience thinking, the analysis suggested that resilience could be analysed as existing in desirable and undesirable forms. Undesirable resiliencies reinforced the vulnerable state. By addressing the factors that sustain vulnerability, response capacity could be enhanced. This being the case, advanced by this thesis is a shift from focusing on resilience as a utopian goal, in favour of practices that enhance response capacity and letting communities learn for themselves and transform their value sets to ones that are more likely to ensure coping with adverse conditions. The study concludes that the concept of resilience in its current form is of more value as an organising framework within the re-engineering of food, agricultural, development and disaster management policy can be undertaken.

A critical appraissal of the home-based food security projects with reference to layers at Makhuduthamaga Sekhukhune District in Limpopo Province

Monyela, Mante Thabitha Daisy January 2007 (has links)
Thesis (M.Sc) (Agriculture) --University of Limpopo, 2007. / It is beyond doubt that a large proportion of the population in the rural areas are experiencing great difficulty in securing adequate food in both amount and quality. Poverty alleviation programs are embarked in various countries with Makhuduthamaga being no exception. The study was designed to evaluate the home-based egg production projects. The study was conducted at Makhuduthamaga sub- District of Sekhukhune District of Limpopo province. Two instruments were used for data collection namely Delphi technique and two structured questionnaires. The Delphi technique was used for both the beneficiaries and the extension officers to identify, list and rank in order of importance the constraints which impacted negatively on egg production as well as the actions taken to address those constraints. Two separate questionnaires were also used to collect data from both the beneficiaries and the extension officers. Out of twenty villages a list of 231 beneficiaries of starter up packs was identified. Krecjcie and Morgan (1970) sample estimation required 144 randomly selected beneficiaries of starter up packs to participate in the study which reflected 0.6 margin of error. The two questionnaires with open ended and closed ended questions were piloted at Fetakgomo District in four villages with thirty one beneficiaries and ten extension officers. Reliability was found to be 0.81 skills, 0.80 for support from extension officers and 0.61 for government expectations. The Statistical Package for the Social Sciences was used for the entering data collected. Descriptive statistics were used to analyse data. The findings revealed that the majority of the beneficiaries fall within the prescribed selection criteria. Almost all except one village were given the starter up packs namely 18 layers, four bags of laying mash, cage, nipples, feeding trays and a cage as outlined in the policy. Training was considered by both the beneficiaries and the extension officers as inadequate for effective and efficient running of the home based egg production projects. The results revealed that the majority of beneficiaries did not meet government expectations. An acknowledgement was made that during the implementation of projects mistakes were committed by both beneficiaries and extension officers. Analysis of variance was also used to determine the relationship between the level of education and the extent to which government expectations were met. There was no significant relationship between skills such as technical, management, financial, administration and the extent to which government expectations were met. However there was a significant relation between marketing skills and levels of education. The majority of beneficiaries had a low level of education. Pearson correlation coefficient was used to determine whether there is a relationship between skills and support from the extension officers and the extent to which government expectation were met. Skills such as technical and marketing as well as the support from the extension officers attributed much to variations with regard to the extent to which government expectation were met. Constraints were also encountered which impacted negatively on egg production. Extension officers identified the following constraints such as survey not done prior to distribution, insufficient human resources, training, insufficient monitoring, inadequate transport, inability of beneficiaries to purchase feed, inadequate starter packs and failure to establish cooperatives. Beneficiaries identified constraints such as feed, training, diseases and unavailability of veterinarian, mortality of layers on arrival, theft and predation, inadequate starter packs, layers not of the same age and cages that are too small. Out the constraints mentioned only three namely insufficient transport, inadequate starter up packs `and one aspect on feed i.e. soft shelled eggs were addressed. Although the majority of beneficiaries considered home based egg production projects inadequate in providing access to adequate food, slightly over half of them favoured them as future household projects. / Kellog Foundation

Evaluation of Challenge Programme Water for Food techniques / technologies on smallholder dryland farming in Greater Giyani Municipality in Limpopo Province

Manganyi, Ntsamatiko Josephina January 2011 (has links)
Thesis (M.Dev.) --University of Limpopo, 2011 / Food security in most drought-stricken areas of Limpopo Province is a challenge to the Department of Agriculture and to all the people living in the province, especially to the resource poor smallholder farmers. Finding remedial solutions to agricultural production in stress prone conditions is therefore a high priority. The introduction of Challenge Programme Water for Food (CPWF) technologies/techniques to smallholder dry land farming in Greater Giyani Municipality was seen as one of the solutions. However, there are constraints raised by CPWF technology adopters such as shortage of labour, lack of ploughing equipment, lack of credit, shortage of land and marketing. CPWF technologies are suitable for smallholder dry land farming, especially rainwater harvesting technologies. Smallholder farmers need to be remobilised and trained on the potential benefits of CPWF technologies to enhance their adoption and spread to other areas.

Urban agriculture a livelihood strategy for food security in the Cape Flats: A case study of community-based and home food gardens in Khayelitsha, Cape Town

Mfaku, Abongile January 2019 (has links)
Magister Artium (Development Studies) - MA(DVS) / Growing urban food insecurity has prompted many researchers, NGOs, international agencies and governments to advocate for urban agriculture as a livelihood strategy to improve the household food security of the urban poor. Urban agriculture is an instrument for ensuring greater food security and a livelihood strategy for urban households. In South Africa increased attention on urban agriculture is triggered by current trends of urbanization, economic instability, high unemployment rates among the urban poor, and high food prices. Unemployment and urban food insecurity are high in low-income areas. In the Cape Flats, households with no or little disposable income, are food insecure and vulnerable to food insecurity. Income and wage employment are the main determinants of food security in urban areas. However, urban agriculture projects by two NGOs assist communities to be resourceful. Abalimi Bezekhaya, an NGO assists individuals and communities to start and maintain their own community gardens while Soil for Life promotes home food gardens. Abalimi Bezekhaya and Soil for Life seek to address the urban challenge by promoting self-sustained agriculture for food security and livelihoods. There has, however, been little empirical evidence suggesting that urban agriculture projects improve the food security and livelihoods of participants. This study assessed the potential of urban agriculture to address food security, examined the ways in which agriculture is used as a livelihood strategy for household food security, determined other livelihood strategies and coping mechanisms assumed by gardeners to become food secure, and demonstrates the contribution of NGOs in promoting agriculture in poor urban areas. Furthermore, this study addressed the following research questions: do community and household gardens provide a way of improving food and nutrition security and in what way are these impacts observable within participating households. The research followed a mixed-method methodology. The literature is mapped out using international and local papers and empirical evidence collected on the subject. This study used the sustainable livelihoods approach as the theoretical lens through which to analyse the ways in which urban agriculture can be used as a viable livelihood strategy by urban gardeners. It also classified the constraints and opportunities, assets accessible, policies and institutions that exist, livelihood strategies and outcomes of the urban gardeners. The findings of the study reveal that community and home gardens contribute moderately to livelihoods and food security in Khayelitsha. The results also reveal that 85% of the gardeners were either moderately or severely food insecure. Furthermore, 76.67% of gardeners purchased their food from supermarkets and local shops. Urban agriculture therefore plays a supplementary role in addressing household food security in Khayelitsha. The potential of community and home gardens to contribute to urban household food security and livelihoods is limited access to land and government assistance. There is a need for the City of Cape Town and the Department of Agriculture to assist and strengthen the practice of community and home gardens in Khayelitsha.

Surviving in a Socio-Economic Crisis: Strategies of Low Income Urban Households in Dzivaresekwa: Zimbabwe.

Magunda, Douglas. January 2008 (has links)
<p>For close to a decade, Zimbabwe has experienced a protracted socio-economic crisis. Although it is affecting both rural and urban areas, major forms of formal safety nets by the Government and Non-Governmental Organisations have been confined to rural areas. On the other hand the virtual collapse of the formal food marketing system in urban areas and the high formal unemployment rates have contributed to increased vulnerability of low income urban households to food insecurity. Using qualitative research methods, the study set out to understand livelihoods of low income urban households in Dzivaresekwa. In particular strategies low income households employ to cope with the negative macro-economic environment prevailing in Zimbabwe.</p>
