An investigation of cultural influences on fertility behaviour among university students at Howard College, UKZN-Durban.Mbaya, Thokozile Jocylen. 02 December 2013 (has links)
Questions have been raised regarding factors influencing fertility in South Africa, particularly within the different population groups. Various studies have focused on fertility in South Africa and other developing countries, based on racial differences, socio-economic statuses and geographical or environmental factors. It is clear that the major omission in the existing studies is the much-needed investigation of cultural influences on fertility outcomes. Therefore, this study is an investigation of the role of culture in influencing fertility behaviour among young women at the University of Kwa-Zulu Natal, Durban. The central question of this paper is therefore: how does culture influence fertility behaviour among young university women? To respond to this question, the study used John Bongaarts' theory on proximate determinants of fertility as lenses for this investigation. A qualitative research design was used to collect data through 14 individual in-depth interviews with multiracial and multicultural women between the ages of 22 and 31. A thematic analysis revealed that culture still plays a significant role in determining fertility outcomes. Although the participants are aware of the conservative stand of their cultures and religions, the results indicate that their personal choices for fertility behaviour are influenced by education and desire for success in their careers. In addition, the findings showed that the extent to which culture influences fertility behaviour is different across the various racial groups in South Africa. / Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2012.

Perceptions of students at the University of KwaZulu-Natal, South Africa, regarding factors influencing high fertility rates among young people.Yunos, Hajira. January 2010 (has links)
Fertility among young people has increased globally and is a major concern, particularly in developing countries. Sub-Saharan Africa is a region that is greatly affected by poverty; HIV/AIDS and an increasing population. Young people are engaging in unprotected sex and this not only increases their risk of having an unplanned pregnancy, but also increases the risk of them contracting HIV and other sexually transmitted infections. In Southern Africa, pregnancy rates among young people are high even though total fertility rates have declined. Many interventions have been implemented to directly address this issue; however, it is perplexing as to why pregnancy rates among young people are so high.
Studies have indicated that there are many factors that influence unplanned pregnancy rates among young people. The aim of this dissertation is to understand the reasons for high fertility rates among young people in South Africa. This study draws on qualitative methodology using in-depth interviews with 20 female students at a tertiary institution in KwaZulu Natal, South Africa.
Students interviewed presented a number of reasons for the high levels of pregnancy among young people. The study findings highlighted that young women have knowledge of contraception and are aware of the importance of contraception in preventing an unplanned pregnancy; however, contraception is being practiced inconsistently and incorrectly. Students are more afraid of the risk of an unplanned pregnancy than HIV/AIDS. Poor interpersonal relations with health service providers were perceived as a common barrier preventing young women from accessing contraception at the local clinics. Furthermore, the interviews suggest that peers exert an enormous influence over young people. / Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2010.

Phosphorous dynamics in soils under contrasting long-term agricultural management practices in the KwaZulu-Natal midlands.Majaule, Ugele. January 2006 (has links)
Little is known regarding the effects of land use on soil organic matter and P
status of South African soils. For that reason, the effects of the main
agricultural land uses in the midlands region of KwaZulu-Natal [maize (Zea
mays), sugarcane (Saccharum spp), annual ryegrass pasture (Lolium
multiflorum), permanent kikuyu pasture (Pennisetum clandestnum), gum
(Eucalyptus grandis) and pine (Pinus patula)] on soil organic matter content,
microbial biomass C and P and inorganic and organic P pools derived from a
modified Hedley P fractionation was investigated on two sites where the longterm
history of land management was known.
In comparison with undisturbed native grassland, permanent kikuyu pasture
resulted in an increase in organic C, organic P and microbial biomass C and
P. Maize and sugarcane production resulted in a decrease in organic C,
organic P and microbial C and P. Under annual pasture, gum and pine
forests, organic matter and microbial biomass concentrations remained similar
to those under native grassland. Under native grassland, extractable organic
P accounted for 50% or more of the total P content of soils but under
agricultural management with regular applications of fertilizer P, there was an
increase in the percentage of total P present as inorganic P.
Agricultural management greatly affected the distribution of P among the
various inorganic and organic P fractions. Resin-Pi and NaHC03-Pi (the
potentially-available forms of Pi) showed similar trends with land use being
greatly elevated under kikuyu pasture at both sites and sugarcane and maize
at one site. This accumulated Pi was thought to have originated from recent
fertilizer applications and possibly recently mineralized organic P. Trends for
NaOH-Pi with land use differed greatly from those of the Resin- and NaHC03Pi
fractions. Concentrations were notably high under maize and sugarcane
production. Of the pools of soil organic P, the NaHC03-Po fraction was most
greatly affected by land use, being elevated under kikuyu and decreased
under maize and sugarcane. This supports the assertion that it is the
NaHC03-Po fraction that is the most labile soil organic P pool. It was concluded that land use greatly affects soil organic C and P status, soil
microbial biomass C and P contents, soil inorganic P concentrations and the
distribution of P among the various P fractions.
A short-term (8 weeks) laboratory incubation experiment was carried out to
compare the effects of inorganic (KH2P04) and organic (cattle manure, poultry
manure and maize crop residues) sources of P, applied at a rate equivalent to
30 kg P ha-1
, on soil inorganic and organic P fractions and the potential
availability of soil P. Additional treatments consisted of lime [Ca(OHhl at 5 ton
ha-1 and lime plus inorganic P. Applications of lime raised soil pH to a similar
extent after 1, 4 and 8 weeks incubation. After 8 weeks, a small increase in
soil pH was also noted for the cattle and poultry manure and maize residue
treatments. For the inorganic P fractions, substantial treatment effects were
observed only for the Resin-Pi fraction. The inorganic P source was more
effective than the organic ones at increasing Resin-Pi after 1 and 4 weeks
incubation and of the organic sources, cattle and poultry manure were more
effective than maize residues. Resin-Pi concentrations generally increased
between 1 and 4 weeks incubation but then declined rapidly between 4 and 8
weeks incubation. After 8 weeks incubation, treatment effects on Resin-Pi
were small. Concentrations of NaHC03-Pi, dilute HCI-Pi and concentrated
HCI-Pi all declined over the incubation period. There was no clear trend with
incubation for NaOH-Pi although for the poultry manure and maize
treatments, concentrations declined between 4 and 8 weeks incubation. In
general, concentrations of NaHC03-Po were greater for organic than
inorganic P sources after 8 weeks incubation suggesting microbial
immobilization of P in these treatments. There were increases in NaHC03-Po
and concentrated HCI-Po over the incubation period suggesting progressive
immobilization of P from the Pi fractions that declined in concentration during
the incubation. Concentrations of NaOH-Po were not greatly affected by
incubation period. The lime treatments, however, had lower NaOH-Po
concentrations than the others suggesting that liming may have stimulated
microbial mineralization of Po. Residual-P concentrations increased over the
incubation period. This was attributed to conversion of extractable Pi fractions
into recalcitrant, non-extractable Pi forms and/or immobilization of Pinto
intransigent organic forms. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

The use of scientific and indigenous knowledge in agricultural land evaluation and soil fertility studies of Ezigeni and Ogagwini villages in KwaZulu-Natal, South Africa.Buthelezi, Nkosinomusa Nomfundo. January 2010 (has links)
In the past, the indigenous knowledge of soils of small-scale farmers in South Africa has been largely ignored in scientific research. Hence the use of scientific approaches to land evaluation has often failed to improve land use in rural areas where understanding of the prescriptive scientific logic is lacking. Despite this, it is clear that local people and smallscale farmers have knowledge of their lands based on soil and land characteristics that remain largely unknown to the scientific community. It is therefore important for researchers to understand farmers’ knowledge of soil classification and management. To address this issue, a study was conducted in the uMbumbulu area of KwaZulu-Natal to investigate the use of indigenous knowledge as well as farmers’ perceptions and assessments of soil fertility. A preliminary questionnaire was designed to explore indigenous knowledge in a group interview that was conducted prior to the study. Another questionnaire was used to elicit indigenous knowledge from 59 randomly chosen homesteads representative of the population of Ezigeni and Ogagwini villages. Six homesteads were chosen for further detailed information on the cropping history, knowledge specific to the cultivated lands, detailed soil description and fertility. Soil samples were taken from these homesteads under different land uses (taro, fallow, veld and vegetable) at 0-30 and 30-60 cm depth for laboratory analysis. This was done to determine the effect of land use on soil physical and chemical properties and soil microbial activity. For scientific evaluation a general purpose free soil survey was conducted to produce land capability and suitability maps. Farmers identified ten soil types using soil morphological characteristics, mainly soil colour and texture. These soil properties were also used in the farmers’ land suitability assessment. In addition, slope position, natural vegetation and village location were used to indicate land suitability. The amount of topsoil was also used in land evaluation. However, slope position was considered the most important factor as it affects the pattern of soils and hence their suitability. Soils on the footslope were considered more suitable for crops than those found on the midslope and upslope. The yield difference observed between villages, which were higher in Ogagwini than Ezigeni, was also used as a criterion for evaluation. Farmers attributed these yield differences for various crops to the effect of soil type on productivity. In support, scientific evaluation found that Ezigeni village had a number of soils with a heavy textured, pedocutanic B horizon and hence a relatively shallow effective rooting depth. Moreover, the Ezigeni village land suitability was limited in places by poor drainage and stoniness. These limitations were rarely found for the Ogagwini village soils. Farmers had a total of six comprehensive and well defined soil fertility indicators, namely crop yield, crop appearance, natural vegetation, soil texture, soil colour and presence of mesofauna. Results showed that farmers’ fertility perceptions are more holistic than those of researchers. However, despite this, their assessment correlated with soil analysis. There was a close relationship between scientific and indigenous suitability evaluation for three commonly cultivated crops (taro, maize and dry beans). This was further substantiated by yield measurements which were significantly higher for Ogagwini as rated by both farmers and scientific evaluation as the more suitable. The significant agreements between the scientific and indigenous approaches imply that there are fundamental similarities between them. Recognizing this and subsequently integrating the two approaches will produce land use plans relevant and profitable for both small-scale farmers and scientists. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2010.

The practice, constraints and perceptions of improving soil quality through manure application : a case study of three smallholder farmer groups.Naidoo, K. D. 23 August 2010 (has links)
Land degradation and soil nutrient depletion have become serious threats to agricultural productivity in sub-Saharan Africa. Soil fertility depletion in smallholder areas has been cited as the fundamental biophysical cause of declining per-capita food production in Africa. Manure application is a well established and known practice, but not effectively used among South African smallholders. This study investigated the practice, constraints and perceptions of improving soil quality through manure application through a case study of three smallholder farmer groups. Three groups from rural areas of KwaZulu-Natal (Mkhambatini, Mooi River and Richmond) were selected to participate in the study. Participatory methodologies were used to identify and clarify the study problem. Three participatory focus group discussions, one per area, were conducted with farmers at the study sites to discuss farming methods, experience and perceptions of manure use, manure management practices and constraints farmers experience with manure use. Force Field Analysis was used for each group to explore for forces against and in support for manure use. Random soil and manure samples were collected for laboratory analysis to determine fertility levels. Some farmers indicated that soil fertility was low. However, half the sample perceived the land to be productive to some extent. The study showed that 40 per cent of farmers reported improved soil fertility following the application of manure. Due to the limited availability of livestock manure, farmers prefer to use both livestock manure and commercial fertilisers. Furthermore, the study found that except for young farmers (20 per cent of the sample), farmers had not received formal training and very limited extension advice on composting and manure use and management. The study participants were aware of the consequences of declining soil fertility and were attempting to improve soil quality. However, low livestock numbers and poor management led to inadequate amounts of manure, and, limited access to information on manure and compost use. Unless better knowledge of optimal soil nutrient management practice is acquired by the farmers, soil fertility levels will continue to decline, further reducing production potential and rural household food security. Government needs to revisit extension support to meet the needs of smallholders and offer training on sound soil management, sustainable production methods, composting and livestock management. A handbook with graphic detail should be accompanied to provide smallholders with information and advice on how to manage soil fertility. / Thesis (M.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2009.
