Growing sustainable food systems : a study of local food distribution initiatives in Stellenbosch

Landman, Annie Petronella 03 1900 (has links)
Thesis (MPhil)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: This thesis investigates practical approaches to growing sustainable food systems. It first establishes the condition of the global environment within which food systems function and critically assesses previous efforts to grow sustainable food systems. After applying these findings to a set of case studies on local-food distribution in Stellenbosch, I recommend ways for the local-food distribution network to encourage the growth of a sustainable Stellenbosch food system. The literature review provides an overview of the global environment in relation to food systems and lists certain contextual challenges that food systems must address to become sustainable. These challenges are social inequality, an urban future, degraded ecosystems, climate change, energy constraints, a growing global population and food insecurity. The literature review also describes how commercialisation has disembedded food systems from their contexts. This disembeddedness loosens the feedback loops food systems require to effectively respond to contextual challenges and consequently hinders their sustainability. The critical overview of previous attempts to re-embed food systems provides insight into practical ways of growing sustainable food systems. The overview demonstrates that while localisation and the building of social capital should not be seen as the ultimate goals of sustainable food systems, they can be useful mechanisms for nurturing sustainability if applied carefully. The case studies describe ten local-food distribution initiatives in Stellenbosch, and are informed by numerous in-depth semi-structured interviews. My conceptual framework contrasts each initiative’s self-reported vision, perceived reality, and realised actions; this highlights the conceptual and physical network connections between various local-food distribution initiatives, as well as the factors preventing and promoting their sustainability. The case studies show that although a local-food distribution network exists in Stellenbosch, it is fragile and lacks defined conceptual connections. This in turn constrains the formation of physical connections and thus the food system’s progress toward sustainability. The local-food distribution network in Stellenbosch can catalyse the growth of a sustainable food system because its initiatives focus on localisation but do not see it as a final objective. This shared focus indicates that localisation already constitutes a practical tool in the growth of a sustainable food system; however, the network’s lack of social capital still needs to be addressed. Inclusive projects designed to create and protect intellectual, political and economic spaces for reflection within the food system can generate the social capital necessary to grow a sustainable food system. The realisation of a sustainable Stellenbosch food system therefore depends on those with the capacity and resources to initiate the necessary changes. / AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek praktiese benaderings waarmee volhoubare kossisteme bevorder kan word. Dit stel eerstens die toestand van die globale omgewing waarin kossisteme funksioneer vas en oorweeg krities vorige pogings wat volhoubare kossisteme probeer bevorder het. Na ek hierdie bevindings toepas op ’n stel gevallestudies van inisiatiewe wat plaaslik-geproduseerde kos in Stellenbosch versprei, kom ek met voorstelle vorendag vir dié verspreidingsnetwerk om die groei van ’n volhoubare Stellenbosch-kossisteem aan te moedig. Die literatuurstudie omskryf ’n oorsig van die globale omgewing met betrekking tot kossisteme en lys sekere kontekstuele uitdagings wat kossisteme moet aanspreek om volhoubaar te wees. Die uitdagings is maatskaplike ongelykheid, ’n verstedelikte toekoms, verswakte ekosisteme, klimaatsverandering, energiebeperkings, ’n groeiende globale bevolking en voedselonsekerheid. Die literatuurstudie bepaal ook dat kommersialisering kossisteme uit hulle omgewings ontwortel. Hierdie ontwortelling verswak die terugvoerbane wat kossisteme benodig om effektief op kontekstuele uitdagings te reageer en verhoed hulle volhoubaarheid. Die kritiese oorsig van vorige pogings om kossisteme nuwe wortels te laat skiet gee insig tot praktiese maniere om volhoubare kossisteme te bevorder. Die oorsig wys daarop dat terwyl lokalisering en die bou van maatskaplike kapitaal nie as die slotsom van volhoubare kossisteme beskou moet word nie, albei nuttige tegnieke kan wees vir die aankweek van volhoubaarheid indien hulle met sorg aangewend word. Die gevallestudies beskryf tien verspreidings-inisiatiewe van plaaslik-geproduseerde kos in Stellenbosch en is ingelig deur verskeie in-diepte, semi-gestruktureerde onderhoude. My konsepsuele raamwerk kontrasteer elke gevallestudie se self-verklaarde visie, veronderstelde realiteit en gerealiseerde aksies. Dit lig die begrips- en fisiesenetwerkkonneksies tussen die inisiatiewe uit en stel ’n aantal faktore bloot wat die netwerk se volhoubare groei positief en negatief beïnvloed. Die gevallestudies wys daarop dat alhoewel ’n verspreingsnetwerk van plaaslik-geproduseerde kos in Stellenbosch bestaan, dié netwerk swak is en omskrewe begripskonneksies kort. Om die beurt verhinder dit die formasie van fisiese konneksies en weerhou die kossisteem se vordering na volhoubaarheid. Die verspreidingsnetwerk van plaaslik-geproduseerde kos in Stellenbosch kan die groei van ‘n volhoubare kossisteem kataliseer omdat die inisiatiewe waaruit dit bestaan deur ’n gemeenskaplike fokus op lokalisering verbind word, maar dit nie as hulle einddoel beskou nie. Hierdie gedeelde fokus wys daarop dat lokalisering reeds ’n bruikbare tegniek vir die groei van ‘n volhoubare kossisteem is, maar die tekort aan maatskaplike kapitaal binne die netwerk moet steeds aangespreek word. Inklusiewe projekte wat saamgestel word om intellektuele, politiese en ekonomiese ruimtes vir besinning binne die kossisteem te bevorder en te bewaar, kan die nodige maatskaplike kapitaal kweek om ’n volhoubare kossisteem te vestig. Die verwesenliking van ’n volhoubare Stellenbosch-kossisteem hang dus van diegene af wat die kapasiteit en hulpbronne het om die nodige veranderings in te lei.

Commercial agriculture in the Swartland : investigating emerging trends towards more sustainable food production

Metelerkamp, Luke 03 1900 (has links)
Thesis (MPhil)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: The aim of this thesis was to determine whether or not examples exist of commercial grain farmers in the Swartland region of South Africa moving away from high-external-input agricultural production systems towards production systems based on ecologically restorative partnerships with soils and other natural systems. The research also sought to understand why these farmers were changing their approach to farming, as well as investigating the specific technologies and practices they were implementing in order to achieve these changes. In addition, the thesis also considered the theoretical implications of these changes on food security in the Western Cape. Three research approaches were employed: qualitative case studies of seven progressive farmers in the region; a literature review; and an analysis of secondary data. Throughout these three approaches, Swilling and Annecke’s conceptualisation of a multifaceted global polycrisis was used as a conceptual reference point. This was done with the intention of providing an agricultural analysis which looks beyond the farm gate and takes cognisance of the broader socio-ecological issues which affect and are affected by agriculture. The research identified seven farmers who are shifting towards lower-external-input production methods, which focus on enhancing beneficial partnerships with natural systems. The on-site interviews and observations revealed that the degree to which these seven farmers were altering their practices varied significantly. However, four key technologies and practices were identified as being common to all seven farmers: the use of legume rotations, reduced tillage, new styles of planters and increasing farm size. With regard to food security, the research suggested that current changes in these farmers’ agricultural practices could assist in keeping food prices and food production levels more stable in future, compared to production using high-external-input practices previously employed by the farmers. The potential improvement in production stability was shown to result mainly from improvements in soil health, as these improvements give crops increased resilience to unfavourable weather conditions, greater disease-resistance and improved vitality. The potential improvement in price stability stemmed predominantly from increased input-use efficiency and the utilisation of natural fertility and pest-management practices which were less susceptible to monopolistic input sales structures, international shortages and the increasing cost of fossil fuels. Due to the small size of the case study sample and the fact that this research focussed specifically on farmers who were considered progressive, the findings presented in this thesis cannot be viewed as representative of the larger agricultural region. The intention was rather to establish the positive changes currently underway, in order to provide useful pointers for similarly beneficial changes to be implemented elsewhere. / AFRIKAANSE OPSOMMING: Die doel van hierdie tesis was om vas te stel of voorbeelde bestaan van kommersiële graanboere in die Swartlandgebied van Suid Afrika wat wegbeweeg van hoë-eksterne-inset produksie sisteme na sisteme wat gebasseer is op vennootskappe met grond en ander natuurlike sisteme. Die doel van dié vennootskappe isom ekologiese herstellingte bewerkstellig. Die navorsing het ook gepoog om te verstaan hoekom hierdie boere hulle boerderytegniekeverander; spesifieke tegnologieë en praktyke wat gebruik word om verandering mee te bringis ondersoek. Daarenbowe oorweeg hierdie tesis ook die teoretiese implikasies van die veranderings op voedselsekuriteit in die Wes-Kaap. Drie navorsings benaderings is te werk gestel: kwalitatiewe gevallestudies van sewe vooruitstrewende boere in die area; ‘n literatuurstudie; en ‘n analise van sekondêre data. Swilling en Annecke se konsepsualisering van die veelvoudig-gefasetteerde globale polikrisis is deurlopend gebruik as ‘n konsepsuele verwysingspunt. Dit is gedoen om‘n boerdery analise daar te stel wat verby die plaashek kyk na wyer maatskaplike en ekologiese kwessies wat ‘n wederkerige verhouding met boerdery het. Die navorsing het sewe boere geidentifiseer wat na laer-eksterne-inset produksie metodes beweeg. Hierdie metodes fokus daarop om voordelige verhoudings met natuurlike sisteme te versterk. Onderhoude en waarnemings op die plase het vasgestel dat die graad van praktykverandering merkwaardig tussen die sewe boere verskil. Nietemin, vier gemeenskaplike sleuteltegnologieëenpraktyke is geidentifiseer: die rotasie van peulgewasse, verminderde grondbewerking, nuwe plantermodelle en die vergroting van plaasgroottes. Met betrekking tot voedselsekuriteit vind die navorsing dat huidige veranderings in die wyse waarop geboer word, in vergelyking met die voorafgaande hoe-eksterne-inset produksie praktyke, kospryse en produksievlakke kan stabiliseer. Die navorsing wys daarop dat ‘npotensiële verbetering in produksie stabiliteit ‘n uitkoms van gesonder grond is. Gesonder grond verhoog gewasse se vermoëom effektief op ongunstige weerkondisies te reageer, bevorder hulle pes-afweringvermoë en verbeter die lewenskragtigheid van gewasse. Die potensiele verbetering in die stabiliteit van pryse is ‘n nagevolg van meer effektiewe gebruik van insette en die gebruik van natuurlike vrugbaarheid en pesbestuurpraktyke wat minder vatbaar is vir monopolistiese inset-verkoopstrukture, internasionale tekorte en die prysverhoging van fossielbrandstowwe. Na aanleiding van die klein skaal van die gevallestudies en die feit dat die navorsing spesifiek gefokus het op vooruitstrewende boere, verteenwoordig die bevindings in hierdie tesis nie die omliggende landbou area nie. Die veronderstelling was eerder om die positiewe veranderings wat tans onderweg is vas te stel om sodoende bruikbare advies aan soortgelyke voordelige veranderings wat elders geimplementeer kan word te verskaf.

An urban-agricultural hub, Umngeni, Durban.

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

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

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

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

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

Farm level cost-benefit analysis of conservation agriculture for maize smallholder farners in Okhahlamba Municipality in Kwa-Zulu Natal Province, South Africa

Tafa, Sanelise January 2017 (has links)
Land degradation is a serious problem that many poor communities face and this worsens their vulnerability and therefore, poses a threat to food security, as it reduces yield, forces farmers to use more inputs, and disproportionately affect the smallholder farmers in remote communities that also suffer diverse infrastructure disadvantages. In response to that, the international development agencies, donors, and Non-Governmental Organizations (NGOs), especially faith-based organizations have turned towards sustainable farming approaches. Much attention has been paid to a combination of sustainable farming measures which are packaged under the “Conservation Agriculture” (CA) banner. The previous work in the KZN Province and elsewhere has demonstrated that CA has the potential to improve the soil structure, thereby reversing the effect of soil degradation. Consequently, many of the farmers in the areas in which these demonstrations have been conducted appreciate the ecological and economic value of adopting CA. However, the on-farm financial benefits of adopting a CA specific tillage practice are not as well known or thought to be as pronounced. By means of integrating field survey, reviewed literature, and econometric analysis, this study assessed the farm level cost-benefit analysis of conservation agriculture for smallholder maize farmers in OLM, specifically in one demonstration village of Bergville town. The analysis is based on the case study of the NGO’s work in which they had selected a community and participating households who received assistance in a number of ways such as maize seed, soil preparation, and CA planters. To analyse the farm level cost-benefit analysis, descriptive, linear regression, gross margin (GM) and appraisal indicators such as Net Present Value (NPV), Benefit Cost Ratio (BCR) and Internal Rate of Return (IRR) were used. The descriptive analysis, used to analyse the factors affecting the extent of adoption of CA revealed that socio-economic characteristics have the influence on the level to which a farmer responds to incentives. Linear regression model used in this study showed that years in farming, involvement in joint farmer’s group, and use of cover crops have the significant effect on the extent of adoption of CA. Moreover, the calculated gross margins of the two tillage systems were different, revealing higher Gross Margins for CA plots than for conventional plots. The major cause of the difference was found to be differences in the variable costs. When using appraisal indicators (NPV, BCR, and IRR) the study projected a 10-year period at 8% and 10.5% discount rates. The study also revealed positive NPVs for both CA and conventional agriculture. The positive sign implies that there are positive pay-offs for investing in both trial and control plots. However, trial plots have larger NPVs compared to control plots, meaning that there are less additional returns for investing in control plots compared to trial plots. Results also reveal that with 10.5% discount rate, the NPVs are lower than with 8% discount rate, showing that lower discount rates are consistent with higher performance over the long term. This therefore means that at lower discount rate, it is more viable to produce maize using CA than using conventional tillage system. In the case of BRC presented in the study, it was revealed that at both low and high discount rates, the trial plots were more viable than the control plots. Finally, the IRR presented in the study reveal that the trial plots would be able to pay their way much faster than the control plots. Overall, the study found that there are incentives to adoption of CA compared to conventional farming. The message from the different results arising from the use of different discount rates is that farmers should receive assistance at low cost of capital in order for their operations to be viable and this works out well over the long term as shown by the 10-year period projections.

Socio-economic factors influencing the adoption of in-field rainwater harvesting technololgy for enhancing household food security by small holder farmers in the Nkonkobe Municipality, Eastern Cape Province

Shange, Nomfundo Sinethemba Queen January 2015 (has links)
Infield rainwater harvesting (IRWH) technology has been used in arid and semi-arid parts of the world and promising results have been achieved in terms of increasing yield. The main aim of this study was to identify socio-economic factors determining the adoption of IRWH technology for enhancing household food security by smallholder farmers. The specific objectives were to assess the level of adoption of IRWH technology using descriptive statistics (mean, frequency and percentages). To determine socio-economic factors influencing adoption of IRWH technology, the binary logistic regression mode l was used. To determine whether adopters of IRWH technology are more food secure than non-adopters, the Household Dietary Diversity Score (HDDS) was used as a measure for household food security. For the same objective, to determine socio-economic factors that influence household food security, the binary logistic regression model was also used and adoption of IRWH technology became an independent variable. The study was conducted in Khayalethu, Guquka and Krwakrwa villages in Nkonkobe Municipality in the Eastern Cape Province (EC). The unit of analysis was the individual smallholder farmers practicing agriculture. The availability (accidental) and snowball sampling techniques were used to select 34, 23, 63 respondents from Khayalethu, Guquka and Krwakrwa villages respectively. Since they are non-random, these sampling methods are problematic because of sampling errors. Overall, a sample size of 120 smallholder farmers was targeted for the interviews. Primary and secondary data collected was coded and analysed using statistical package for social sciences (SPSS) version 21. Results were presented using graphs, pie charts and tables (including cross-tables). The descriptive results showed that adoption status of IRWH technology was low in these areas, with 79% not adopting the technology. Food insecurity was high amongst the non-adopters with 86%. On the basis of descriptive analysis it can be concluded that any change in each one of the significant variables can significantly influence the probability of adopting IRWH technology and household food security. The results from the logistic regression model for the incidence of adoption revealed that 6 out of 16 variables were significant, three at 1% (access to extension services, access to information and farmers’ perception towards the IRWH technology); one at 5% (access to market) and two at 10% (access to hired labour and farm income). For the incidence of household food security, out of 17 variables, 6 were significant, three at 1% (adoption of the IRWH technology, access to extension services and farmers’ perception towards the IRWH technology); two at 5% (access to hired labour and household income) and one at 10% (household size). The empirical findings of this study indicate that there are socio-economic factors influencing adoption of IRWH technology and household food security amongst smallholder farmers. This study recommends that the government should provide extension officers and research stations with the capacity, support and physical means to expose smallholder farmers to the IRWH technology through demonstrations and trainings. The government can also introduce agricultural finance institutions in rural areas to assist the rural smallholder farmers to increase their access to credit. Further, it is recommended that smallholder farmers can expand to the communal croplands in order to gain more land size and work as a co-operative or as an association to ease labour constraints.

The perceived impact of soil erosion on food security in the upper and lower areas of Didimana in the Eastern Cape of South Africa

Ighodaro, Ikponmwosa David January 2012 (has links)
Due to the particular nature of accelerated soil erosion, its impact on food security is usually very intense. The impact starts first on the farmer, and then to his/ her environment. This is why soil erosion, when unchecked, is very devastating. Therefore this study was set to evaluate the perceived impact of soil erosion on food security in the Upper and Lower Areas of Didimana, Eastern Cape of South Africa, and the role farmers’ adoption behaviours play in the interaction. Three specific objectives were put forward by the study, vis-à-vis: (1) to establish farmers’ perceptions on the impact of soil erosion on food security of the study area; (2) to establish farmers’ innovation adoption behaviour with respect to soil erosion control in the study area; and (3) to establish farmers’ perceptions on the impact of extension activities with respect to soil erosion-control in the study area. The central argument of discussion is that soil erosion like every other agricultural problem, is the result of farmers’ non-adoption or inappropriate adoption of improved and recommended soil management technologies in the study area. The survey method of research was adopted for the study, where data were collected, using a well structured questionnaire, from a total of 60 farmers in the study area, through a simple random sampling process. Farmers’ perception suggested that the impact of soil erosion in their area is severe. This severity is demonstrated firstly in the form of climate change, as the time of rain in their area is gradually changing, and thus changing their time of cropping. Similarly the livelihoods of farmers are being negatively affected, as farmers’ crops, livestock, and even household feeding are being affected. More so, findings indicate that most farmers now plant fewer crops and there is an estimation of crop loss by most farmers of well between 21-60 percent of crops every year. Farmers’ perception further revealed that due to soil erosion, over 50 percent of farmers are unsustainable and a total of 71.7 percent of farmers’ population admitted that the amount of food available for their households is being severely affected. In virtually every sphere of human endeavours improved technologies have been developed to solve human problems, but the main reason problems like soil erosion is still very evident is the fact of farmers’ non-adoption or inappropriate adoption of specific recommended technologies. In the study area, the role of farmers’ adoption behaviour in the interaction of the impact of soil erosion on food security was very prominent. Findings indicate that despite the presence of certain recommended soil management technologies in the study area, majority of farmers do not use them neither extension advices. Moreover their satisfaction with those technologies was found to be low, which could be an explanation why they do not use them. For innovation to be adopted, rejected or utilized inappropriately, the effectiveness and performance of agricultural extension, as well as farmers’ perception play a great role. Thus in the study area, farmers’ perception on extension effectiveness indicates that extension hardly talk about soil erosion and its control during times of their visit. Similarly, farmers’ rating for extension services and advices was as well very low (23.4 percent). In fact, a comparison of farmers’ traditional methods of soil erosion control with extension recommendations (53.4 percent) indicated that farmers perceive their local methods of more importance than extension methods. In the same vein, majority of farmers in the area indicated that extension officers are inadequate in their jobs. Reasons offered range from issues of unreliability, lack of regular visits, communication problems, less attention for crop farming, and other reasons such as extension being unconcerned for subsistence farmers, as well as the fact that they focus more on cooperatives. In all, the findings of the descriptive statistics reveal that the impact of soil erosion on food security in the study area is very significant, and the results of the linear regression model of relationships in the study reveal that soil erosion relates positively with age of farmers, their product quality, and their sustainability. In a similar note, the innovation adoption behaviours of farmers was also found to be positively related to farm yield and food accessibility. Thus showing that innovation adoption behaviour of farmers in the interaction of soil erosion and food security in the study area is significant. Therefore, efforts should be geared toward improving factors that increases yield and accessibility of farmers to serve as boosters of farmers’ motivation towards the adoption of appropriate soil management technologies in their area.

An exploration into the challenges faced by rural communities in the effective use of land for subsistence agriculture for poverty alleviation: a case study of the Mpongo and Twecwana communities in the Eastern Cape

Mlonyeni, Xolani January 2011 (has links)
The escalation of poverty simultaneously with the decline of small-scale agriculture in the rural areas of the Eastern Cape in particular, raises serious concerns within the government circles in South Africa and among researchers. Of the nine provinces of South Africa, the rate of poverty in the Eastern Cape is a pathetic one and is the largest contributor to poverty statistics in the whole of South Africa. Machete (2004) stresses that high levels of poverty are visible in the rural areas and the large proportions of the people who are poor in South Africa are found in the rural areas. It is widely accepted that small-scale agriculture plays a vital role in and contributes substantially to socio-economic life of people living in the rural areas and is one of the strategies most suited to combat poverty for the majority of the people in the rural areas. This study explored the challenges that limit the effective use of land for subsistence agriculture as a strategy for poverty alleviation at Mpongo and Twecwana villages in Tsholomnqa. The study adopted a qualitative approach in order to get in-depth understanding of the challenges as experienced by the participants. The sample comprised of fifteen (15) subsistence farmers and three (3) extension officers from the department of agriculture. The data was collected from the participants through the focus group technique with an interview schedule containing open ended questions. The findings of the study indicated that the communities lack capital such as money, machinery, labour and other resources needed to pursue agricultural livelihoods. The findings also showed that agricultural infrastructure such as dams, rivers, fencing have deteriorated. Machete (2004, p.8) concurring with Pote (2008) says “inadequate physical infrastructure in the rural areas, particular in the former homeland areas remains a major obstacle to smallholder agricultural growth in South Africa”. In the two villages the situation is worsened by a total lack of irrigation scheme development. These communities rely entirely on seasonal and natural rainfall for their crops to be cultivated and grown. It was also found that the introduction of state grants contributed for the rural communities to do way with their traditional socio-economic agricultural livelihoods. The end results were for food production from gardens and communal fields come to a total collapse in many communities in the rural areas. The findings also show that youth is less interested to participate and pursue agricultural based activities in the rural areas. Williams et al (2008) claim that young people are unwilling to pursue agricultural studies as career of choice because of negative image attached to it. Many youths regard agriculture as an activity which belongs to adult and ordinary people. Drought was also cited as the worst natural disaster that has threatened the already disadvantaged small scale agriculture in these rural areas. These deficiencies have rendered subsistence agricultural centred activities to a total collapse.
