Gendered drought effects within family settings, Masvingo Zimbabwe " 2000 to 2016"

Takayindisa, Flora Maruva 20 September 2019 (has links)
PHDGS / Institute for Gender and Youth Studies / This study examines the views, understandings, beliefs and practices on the effects of drought and how women cope in this regard. Feminist theories such as the Standpoint theory, Intersectionality, Ecofeminism and Social Construction were used to conceptualize the gender roles and practices that continue to hinder equity between men and women. This study was qualitative in design. The population of the study comprised of men and women living in Shashe village. A total number of people interviewed was 24, 6men and 6 women from focus group and 12 participants for individual participants. A purposive sample of participants was drawn from the population of farmers. The researchers targeted farmers, who are affected by erratic rainfall. The data was analysed using thematic analysis. The themes that emananted from the study were; environmental effects, economic effects, food scarcity, health effects, distribution of gender roles and coping strategies to drought. The findings showed that there were paradigm shifts in terms of gender relations with regard to drought in many villages, townships and cities today. Furthermore, cultural patterns embedded in patriarchal relationships are accommodating forms of relationships which are not favourable to women. The study recommends that farmers should also have other sources to generate income other than farming because of the changing weather patterns and also to educate women in all dimensions of agriculture so that they are well informed. / NRF

Exploring phosphorus, mucuna (Mucuna pruriens)and nitrogen management options for sustainable maize production in a depleted kaolinitic sandy loam soil of Zimbabwe

Shoko, Munashe 12 1900 (has links)
Thesis (PhD(Agric) (Agronomy))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: Continuous cropping without replenishing the nutrient component of soils will eventually lead to the depletion of soil nutrients. Small scale farmers in Zimbabwe often do not have the financial means to buy fertilizer and this problem is exacerbated by scarcity of commodities such as fertilizers. The use of herbaceous legumes such as mucuna (Mucuna pruriens) can assist to recapitalize soil fertility depletion and improve subsequent maize productivity in sandy loam soils in the small holder farming sector of Zimbabwe. In this study the effect of phosphorus (P) application to a mucuna crop, the effect of mucuna management options and the application of nitrogen (N) to the subsequent maize crop was investigated. The experiment was carried out during the 2007 to 2009 seasons at the Grasslands Research Station in Marondera in Zimbabwe. The soils are classified as humic ferrolsols and are predominantly of the kaolinitic order with sandy loams of low fertility and are slightly acid (pH CaCl = 5.2). A randomized complete block design was used for the effect of P on mucuna productivity and the effect of P and mucuna management options on the soil properties. The treatments were two P rates (P0 and P40 = 0 kg P ha-1 and 40 kg P ha-1 respectively) applied to a preceding mucuna crop, four mucuna management options [1) fallow (F) (no mucuna planted = control), 2) mucuna ploughed-in at flowering (MF), 3) all mucuna above ground biomass removed at maturity and only roots were ploughed-in (MAR) and 4) mucuna pods removed and the residues ploughed-in (MPR)]. A split-plot design was used to study the effect of P application to mucuna, mucuna management options and N rates on the growth and yield of the subsequent maize crop. The four N treatments [N0 = 0 kg N ha-1, N40 = 40 kg N ha-1, N80 = 80 kg N ha-1 and iv N120 = 120 kg N ha-1] were applied to a subsequent maize crop. Growth and development parameters such as biomass production, leaf area index, nutrient content of the foliage and grain yield were determined in the mucuna and maize crops. Soil parameters investigated included nutrient content, pH, bulk density and porosity. Phosphorus application in these particular soil conditions positively influenced mucuna biomass production and therefore enhanced the role of mucuna as a rotational crop by increased positive effects on the subsequent maize crop. The incorporation of above-ground biomass of mucuna had positive effects on all soil properties investigated. The MF and MPR management options increased the soil organic matter (OM) and reduced bulk density which leads to an improvement in porosity (f) of the soil. Mucuna incorporated at flowering (MF) and P40 treatment combination resulted in the highest mineral N, P, potassium (K), calcium (Ca) and magnesium (Mg) levels. A significant three-way interaction (P<0.05) between mucuna management options, nitrogen rates and time was observed in terms of biomass production and all nutrients in the leaves of the subsequent maize crop. The main findings were that the MF management option had the highest biomass and foliar nutrient accumulation through-out all the treatment combinations. In general the MF management option gave the highest maize yield across all the treatment combinations. Incorporation of mucuna biomass into the soil prior to planting a maize crop therefore improve soil physical and chemical qualities resulting in improved soil conditions for a subsequent maize crop which in turn lead to higher maize yields. Including a mucuna rotational crop have a similar effect on maize yield than application of 80 kg ha-1 of fertilizer N. / AFRIKAANSE OPSOMMING: Aanhoudende verbouing van gewasse op dieselfde grond sonder om voedingstowwe aan te vul lei uiteindelik tot die agteruitgang van die grond se vrugbaarheid. Kleinboere in Zimbabwe het meestal nie die finansiële vermoëns om bemestingstowwe te koop nie en die probleem word vererger deur die onbekombaarheid van kommoditeite soos bemestingstowwe. Die gebruik van kruidagtige peulplant gewasse soos mucuna (Mucuna pruriens) kan bydra om grondverarming teen te werk en om die produksie van ‗n daaropvolgende mielie aanplanting in sandleemgronde in ‗n kleinboerstelsel in Zimbabwe te verhoog. In hierdie studie is die invloed van fosfor (P) toediening aan ‗n mucuna aanplanting, die invloed van bestuursopsies van die mucuna en die toediening van stikstof (N) aan die daaropvolgende mielie aanplanting ondersoek. Die eksperiment is tydens die 2007 tot 2009 reënseisoen by die Grasslands Research Station in Marondera in Zimbabwe uitgevoer. Die grond word geklassifiseer as humiese ferrolsols en is hoofsaaklik sanderige leemgrond van die kaolinitiese orde met lae vrugbaarheid en is effens suur (pH CaCl = 5.2). ‘n Volledig ewekansige blokontwerp is gebruik om die invloed van P op die produktiwiteit van mucuna te bepaal asook die invloed van P toediening en mucuna bestuursopsies op grondeienskappe. Die behandelings was twee P vlakke (P0 = 0 kg P ha-1 en P40 = 40 kg P ha-1) wat aan ‗n voorafgaande mucuna aanplanting toegedien is, vier mucuna bestuursopsies [1) braak (F) (geen mucuna geplant = kontrole), 2) mucuna ingeploeg met blomtyd (MF), 3) alle bogrondse mucuna biomassa verwyder by rypwording en slegs wortels ingewerk (MAR) en 4) mucuna peule verwyde en die res van die bogrondse material ingeploeg (MPR)] en vier N behandelings [N0 = 0 kg N ha-1, N40 = 40 kg N ha-1, N80 = 80 kg N ha-1 en N120 = 120 kg N ha-1] toegedien aan ‗n daaropvolgende mielie aanplanting. Groei en ontwikkeling parameters soos biomassa produksie, blaaroppervlakindeks, nutriëntinhoud van die blare en graanopbrengs is in die mucuna en mielie aanplantings ondersoek. Grondeienskappe soos nutriëntinhoud, pH, bulkdigtheid en porositeit is gemeet. Fosfaat toediening aan hierdie spesifieke grondtipe het mucuna produksie positief beïnvloed en dus die rol van mucuna as rotasiegewas verbeter deur positiewe reaksies in die daaropvolgende mielie aanplanting. Die inwerk van bogrondse mucuna biomassa het al die fisiese grondeienskappe wat ondersoek is positief beïnvloed. Die MF en MPR bestuursopsies het organiese materiaal inhoud van die grond verhoog en bulkdigtheid verlaag wat lei tot verbeterde grondporeusheid (f). Mucuna wat tydens blomvorming ingewerk is (MF) lei tot die hoogste minerale N, P, kalium (K), kalsium (Ca) en magnesium (Mg) vlakke. ‗n Betekenisvolle drie-rigting interaksie (P < 0.05) tussen mucuna bestuursopsies, N vlakke en tyd is waargeneem in terme van biomassa produksie en in terme van al die nutriëntvlakke in die mielieblare wat ondersoek is. Die hoofbevindinge was dat die MF bestuursopsie die hoogste biomassa produksie en blaarnutriënt akkumulasie oor alle behandelingskombinasies tot gevolg gehad het. In die algemeen het die MF bestuursopsie die hoogste mielie-opbrengs oor alle behandelingskombinasies tot gevolg gehad. Die inwerk van mucuna materiaal in die grond voordat mielies geplant word verbeter dus fisiese en chemiese toestande in die grond wat grondtoestande verbeter vir die daaropvolgende miegewas en uiteindelik lei tot hoër mielie-oeste. Die insluiting van mucuna as ‘n rotasiegewas het diesefde effek op mielie-opbrengs as die toediening van 80 kg ha-1 N bemesting.

The ruralization of urban spaces in the context of subsistence farming : the case study of Gwabalanda Township, Bulawayo, Zimbabwe.

Chibvongodze, Danford Tafadzwa. January 2013 (has links)
The burgeoning of subsistence agriculture in the townships of Bulawayo, the second largest city in Zimbabwe symbolizes a change in the use of urban space in many cities of the global South. The activity of subsistence agriculture, which in both colonial and post-colonial Zimbabwe has been highly regarded as a rural activity is now a common sight in most townships of Bulawayo, Zimbabwe (RAUF, 2007). Indeed the rise of subsistence agriculture in the residential areas of Bulawayo particularly in the township of Gwabalanda is leading to what I refer to as the ‘ruralization of urban space’, where through practises of subsistence agriculture, elements of rural life have slowly seeped into the everyday life of urbanites (cf. Rogerson, 1993:33; Zeleza, 1999:45). The thesis uses Lefebvre’s (1974) theory of Production of Space to investigate some of the conditions and factors that have influenced the ruralization of urban space in the township of Gwabalanda, as seen in the intensification of a rural-oriented activity of subsistence farm. Using primary data from 17 semi-structured interviews with Gwabalanda residents involved in farming, the thesis intended to interrogate the perceptions and attitudes Gwabalanda residents hold towards the changes in the use of urban space and also examine the possible benefits of urban farming. The investigation of subsistence farming in Gwabalanda led me to identify three complementing and overarching themes or factors that drive urban farming and the ruralization of urban space. The first two themes are the political and economic factors which seem to operate on a macro-level, whereas the other theme of socio-cultural factors functions at an individual or household level. Economic and political factors such unemployment, lack of income, high transport costs of moving food, political alienation and freedom were identified by Gwabalanda residents as important drivers of urban agriculture. On the other hand, socio-cultural aspects which included identity, traditional religion, socialization and changes in migration patterns appeared to be crucial motivators for cultivating urban spaces. The research study also found out that urban households that are engaged in subsistence farming are more food secure and generate extra income from selling some of the produced crops. The income generated is used to pay school fees, pay bills and buy farming inputs for the next planting season. Furthermore some households were sending excess farm produce to their rural homes.

Permaculture as an aspect of environmental learning: an investigation into secondary school communities in Zimbabwe

Nyika, Mugove Walter January 2002 (has links)
The Schools and Colleges Permaculture (SCOPE) Programme in Zimbabwe has developed a process for use by schools in planning for the sustainable management of their land. The process is called Integrated Land-Use Design (ILUD) and is based on Permaculture principles. The ILUD process has so far been implemented in 54 pilot schools where it has been used to facilitate the re-design of the school grounds through the active participation of the students, staff and parents. The aim of this research was to investigate what environmental learning takes place during the implementation of the ILUD process and related activities, with a view to informing the improvement of the process. The research was conducted within the interpretive paradigm with particular use being made of the Symbolic Interactionist theoretical framework to explore the social situations in which the ILUD process has been applied. A purposive sample of two schools and five form 4 (grade 11) pupils from each school was selected for the study. The main data collection method was the structured interview. Other data were collected from nonparticipant observations and the analysis of documents, particularly photographs. The data was analysed using the constant comparative method. The findings point towards a significant contribution from the Permaculture activities to the environmental knowledge, environmental management skills and the positive environmental attitudes of the pupils. The work done at the two schools indicates the usefulness of the ILUD process as a tool for environmental action in the schools but its application in the communities was found to be limited by constraints such as lack of resources and the limited capacity of teachers to work in the field of adult education and training. It is recommended that Permaculture should be integrated into the secondary school curriculum if the momentum of the progress made so far is to be maintained. The SCOPE Programme itself needs to be strengthened for its work with communities. There is, for example, a need for adult education and training methods if the introduction of ILUD to the communities is to be successful.

The effect of literacy on access to and utilization of agricultural information for household food security at Chirau communal lands in Zimbabwe

Gundu, Moira January 2009 (has links)
The research sought to examine the effect of literacy on access to, and utilization of agricultural information for household food security at Chirau Communal lands in Zimbabwe. The study was influenced by the diffusion of innovations approach based on interviews, observation and document study. Selected female farmers from Chirau communal lands were respondents to the self administered interviews and focus group discussions. Representatives from, Agriculture Extension and the Ministry of Agriculture were key informants. Systematic Random sampling was used to select 100 female respondents from the age of 18 to above 80 from wards 1 to 10 of Chirau Rural District in Zimbabwe. Data was analyzed into themes and coded for statistical analysis using the SPSS. The country is faced with food insecurity and the main findings of this study support the view that women play an active role in food production but their potential is limited by inadequate levels of literacy that affect the way they access and utilize resources for sustainable agriculture and household food security among other factors. This may be generalized to the situation of female farmers in Zimbabwe. Improved literacy competencies among the female farmers in Zimbabwe lends itself as one of the interventions that may assist in improving access to information and its effective utilization.. This calls decision-makers to boost literacy for women, develop available agricultural information resources and harness effort towards making them accessible. While interventions may be multi-sectored, the role of government is stressed in this report.

Agricultural mechanization for sustainable agriculture and food security in Zimbabwe: a case of Bindura District in Mashonaland Central Province

Chisango, Future, T January 2010 (has links)
A cardinal development goal of the Zimbabwean government is agricultural mechanization through the acquisition and use of tractors by arable crop farmers in communal and resettlement state land. This research project therefore aimed at investigating the impact of mechanization on agricultural productivity focusing on farmers in Bindura district of Zimbabwe who benefitted under the ongoing farm mechanization program. The existing land policy and the issue of technical efficiency in agricultural productivity are assumed to be the drivers of the program. It is likely that these key issues will constitute an important consideration in determining the sustainability of the mechanization policy. A multistage sampling technique was used to randomly select 90 farmers in the study area. The Cobb Douglas approach and Logistic regression were used to analyze data obtained from the respondents. Results revealed that tractor use was positively influenced by household size, access to extension services and crop output equivalent. Education, land area cultivated, stoniness negatively influenced the probability of adoption of mechanized farming. Furthermore, the technical efficiency estimate of adopter and nonadopters of mechanized farming showed no difference in their level of technical efficiency in agricultural productivity that was 64 percent on average. The level of observed inefficiency was increased by slope, stoniness and household size while age reduced technical inefficiency. It is recommended that government should consolidate the present gains arising from extension services. Also, environmental factors such as slope (topography) and stoniness, which constituted major disincentives in communal areas, could be overcome if government and farmers can identify and open up new areas of farmland for occupation by farmers.

An investigation into the effectiveness of corporate sustainability programmes and initiatives in the agricultural sector : the case of British American Tobacco Zimbabwe

Nyanyirai, Stanley 03 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: In recent years, a great deal of attention has been paid towards the notion of corporate sustainability, which has variously been defined as meaning the incorporation of social, environmental, economic, and cultural concerns into corporate strategy and bottom line. The preliminary investigation suggests that Multi-National Corporations (MNCs) are mainly worried about securing permission for commencing operations and not about the wellbeing of locals and their livelihoods. Further to this, one of the main reasons why efforts aimed at improving sustainability are not yielding significant and lasting results, is that solution seekers in business, science, government and the research community are still operating in the same old paradigm of using basically the same tools and adopting the same world view that threaten sustainability in the first. The key and clear research objectives of this study are:- to ascertain if there is a link between British American Tobacco Zimbabwe (BATZ) top management philosophy, corporate strategy and the company`s corporate sustainability programmes, initiatives and other efforts, and the various stakeholders, and, if so, how these are communicated to them; to establish the degree of integrating sustainable development practice and initiatives into the BATZ business model in order to have long term benefits for both the company and its various stakeholders - these are an integral part of the socio-ecological system, and will help the business understand the resilience of the system and where in the system they should operate; to establish the depth, scope and culture of sustainability in terms of the extent to which they inserted inside (embedded) the BATZ operations; and to ascertain the level of economic, social and environmental effects of BATZ`s corporate sustainability programmes and initiatives in the locality in which it operates. The research used focus group and key informant discussions, one-on-one interviews, and to a limited extent a semi-structured research questionnaire. Information was also accessed from company internal information management portals, and BATZ’s group sustainability and other reports. The conclusion was that renewable energy programmes at BATZ were driven by energy insecurity and scarcity. Currently BATZ is not recycling water used in cigarette manufacturing operations, waste recycling of cut-rag tobacco has been occurring, and BATZ will continue to provide agronomic support to small scale farmers under its Social Responsibility in Tobacco Programmes (SRTP) towards leaf sustainability. The Rocket Barn concept is one of the most innovative intermediate technological breakthroughs meant for improving wood fuel efficiency in tobacco curing. Socially BATZ has done some good works in addressing some of society’s key challenges. There have been benefits for key corporate stakeholders in having BATZ operating in Zimbabwe. The research will assist BATZ to fully understand the socio-ecological system in which it operates; a fundamental understanding to improve corporate sustainability, which will then require a shift in sustainability-oriented efforts. / AFRIKAANSE OPSOMMING: Die idee van korporatiewe volhoubaarheid het die afgelope klompie jare baie aandag geniet. Wyd gesien, kom definisies neer op die insluiting van maatskaplike, omgewings-, ekonomiese en kulturele ondernemings in basiese korporatiewe strategieë. Die voorlopige ondersoek stel voor dat MNK’s wel gemoeid is met die verkryging van toestemming om bedrywe te stig, maar nie juis die welsyn en dag-tot-dag-belange van die plaaslike gemeenskap op die hart dra nie. Volgens (Fiksel 2003) en Du Plessis (2008) is een van die hoofredes waarom pogings om volhoubaarheid te verbeter nog nie betekenisvolle en blywende resultate gelewer het nie, die feit dat die mense betrokke by sake-ondernemings, wetenskap, die regering en navorsing wat na oplossings soek, nog geen paradigmaskuif gemaak het wat hul denkpatrone betref nie. Hulle gebruik steeds dieselfde uitgediende gereedskap en huldig nog dieselfde wêreldsienings wat volhoubaarheid in die eerste plek bedreig het. (Fiksel, 2003, Du Plessis, 2008, Hayward et al 2010). Die doelwitte van die navorsing is: om uit te vind of daar ’n skakel is tussen die filosofie en korporatiewe strategie van BATZ-hoofbestuur en die maatskappy se volhoubaarheidsprogramme, inisiatiewe ens; om te bepaal in watter mate volhoubare ontwikkeling en volhoubaarheidspraktyke en inisiatiewe geïntegreer word in die BATZ-korporatiewe model, om impak vas te stel en die kultuur van volhoubaarheid binne BATZ-bedrywe te bepaal. Die navorsing het gebruik gemaak van fokusgroepe, van sleutelbesprekings deur ingeligte persone, een-tot-een-onderhoude en in enkele gevalle selfs van gestruktureerde vraelyste. Toegang tot inligting is ook verkry deur middel van ‘n maatskappy se interne inligtingsbestuursbronne, BAT-groep-volhoubaarheids- en ander verslae. Die gevolgtrekking is dat hernubare energieprogramme afgedwing is op Batz deur die onsekerheid oor en die gebrek aan energie. Tans word water wat in sigaretbedrywe gebruik word nie deur BATZ herwin nie, maar afval van “cut-rag” tabak word wel herwin, en BAT Zimbabwe sal voortgaan met agronomiese ondersteuning aan kleinskaalboere kragtens sy Maatskaplike Verantwoordelikheid t.o.v. Tabak Programme (MVTP) vir blaarvolhoubaarheid. Die “Rocket Barn-”konsep is een van die innoverendste intermediêre tegnologiese deurbrake om die effektiwiteit van houtbrandstof by die droogmaak van tabak te verbeter. Op maatskaplike vlak het BATZ Zimbabwe goeie werk gedoen deur enkele uitdagings van die gemeenskap die hoof te bied. Die feit dat BAT in Zimbabwe werksaam is, was tot voordeel van korporatiewe belangstellendes. Die navorsing sal BATZ help om die sosio-ekologiese stelsel waarvolgens dit bedryf word, ten volle te verstaan, en om korporatiewe volhoubaarheid te bevorder, wat dan ‘n kopskuif ten opsigte van volhoubaarheidsgeöriënteerde pogings sal vereis.
