Farmers’ strategies and modes of operation in smallholder irrigation schemes in South Africa : a case study of Mamuhohi Irrigation Scheme in Limpopo ProvinceMudau, Khathutshelo Seth 26 October 2010 (has links)
This study was undertaken at a smallholder irrigation scheme in the previously disadvantaged rural area of Mamuhohi in the Limpopo Province. Like other smallholder irrigation schemes in South Africa, Mamuhohi Irrigation Scheme has not performed particularly well. The expectations of interveners like politicians, development agencies and planners have not been realised in smallholder irrigation schemes. Constraints faced by smallholder farmers include a history of dependency; the high costs of mechanisation; the absence of credit, inputs, and output markets; insecure land tenure; “hedgehog behaviour” among smallholders; lack of funding; and poor management and maintenance of infrastructure. The White Paper on Agriculture (NDA, 1995) clearly set out government‘s intention to withdraw subsidies previously enjoyed by farmers and to ensure that the real costs of natural resources are reflected in the pricing of resources in order to discourage abuse. This resulted in the enacting of laws like the new National Water Act of 1998 (DWAF, 1998), aimed at sustainable water management. This included the rehabilitation of infrastructure prior to transfer, and the establishment of water users’ associations amongst farmers, which were to take over ownership and collective management of the schemes. The overall objective of the study was therefore to assess the sustainability and, more specifically, the economic viability of smallholder irrigation schemes in South Africa in the context of irrigation transfer. Hypothesis to be tested: <ul> The behaviour of smallholder farmers is diverse and is reflected in the way in which they view farming and engage in agricultural practices. </ul> The study also sought to indicate the existence of diversity in the smallholder irrigation scheme, by exposing different types of smallholder farmers within the scheme. This information should be of great importance in assisting smallholder farmers regarding issues of their own development. The findings will also help to curb the generalisation of developers’ perceptions regarding smallholder irrigation farmers. Smallholder irrigation farmers are feeling the full impact of the withdrawal of government assistance from the irrigation schemes, which have deteriorated to a state of partial collapse. A great need among farmers remains the rehabilitation of irrigation infrastructure, which would enable them to farm their land. As indicated earlier, the study found that diverse types of smallholder farmers exist within the irrigation scheme. This indicates that appropriate information in this regard is important for government in the formulation of policies aimed at the development of such farmers. Through this study, four types of smallholder farmers were identified within the same irrigation scheme. The methodology applied in achieving the aforementioned outputs pursued a specific sequence, starting with the formulation of questions. The particular study area was chosen due to the likelihood of the presence of different types of farmers that could be identified through the study. A list of the names of smallholders and other key information was provided by the local agricultural office. This assisted with the identification of people to be interviewed. The preliminary interviews were conducted with a sample size of 25 farmers and were aimed at gaining a better understanding of the people within the study area. The questionnaire used during these interviews contained open-ended questions that allowed respondents to express their views and make suggestions. This led to the development of a questionnaire consisting of closed-ended questions, aimed at eliciting responses that were relevant to the purpose of the survey. The questions were also as simple as possible to ensure that they would be clearly understood by both the interviewer and the respondents. About four weeks were spent in trying to understand the real setup of the study area and the lifestyle of the local community. The second step in the methodological sequence was the collection of data from 60 farmers. These interviews were conducted with the assistance of two extension officers. It was not possible to interview all the farmers at once, and it took about two weeks to interview all 60 farmers. Fortunately, the farmers were extremely co-operative throughout the entire interview process. The third step in the methodological sequence was the processing of the data collected during the interviews. The typology here was developed by means of qualitative analysis and had to be refined over a period of time to ensure a valid typology of farmers. This necessitated the use of other data analysis tools, which ultimately contributed towards the classification of farmers according to different types. Four types of farmers were eventually identified, namely: Highly intensive maize growers; Vegetable growers; Diversified maize growers; and Intensive diversified growers. Lastly, the conclusion that can be drawn from the research is that any attempt to develop smallholder irrigation farmers requires an understanding of their diversity – hence this study’s intention to identify, in a scientific manner, the existence of such diversity. Understanding diversity amongst farmers also requires an understanding of the different strategies that farmers employ to ensure their livelihood. This means that both the socio-economic and institutional setting of such farmers must be understood. / Dissertation (MInstAgrar)--University of Pretoria, 2010. / Agricultural Economics, Extension and Rural Development / unrestricted

An impact assessment of the revitalisation of smallholder irrigation schemes program:A case of Tswelopele Irrigation Scheme in Sekhukhune District of Limpopo ProvinceMaepa, Maatla Aaron January 2011 (has links)
Thesis (M.Dev.) --University of Limpopo, 2011 / Agricultural development programs under the former apartheid homeland system which was dissolved in 1994 could not successfully achieve their objectives. The current democratic government reviewed the policies and programs put in place during apartheid era which eventually led to the implementation of the Revitalisation of Smallholder irrigation Schemes (RESIS) in line with the Reconstruction and Development Program (RDP) and Growth, Employment and Redistribution (GEAR) programs. It was anticipated that RESIS would among others improve agricultural productivity, play a role in local economic development, improve food security, provide improved benefits and the livelihoods of the rural communities where the schemes are situated.
The aim of the study is to assess whether the RESIS program has had an impact so as to make recommendations for future similar programs. The objective of the study is to assess the impact of RESIS program on the livelihoods of the participants and to shed light on whether such programs can be used for poverty reduction, which is a key objective in the programs of LDA. Tšwelopele irrigation scheme in Greater Tubatse Municipality within Sekhukhune District Municipality was selected as the area at which the study was conducted.
A random sample of 50 beneficiaries was selected from a total of 75 RESIS beneficiaries and divided into two strata, namely, full-time farmers (both male and female) and part-time farmers (male and female) farmers. Interviews were conducted through completion of questionnaires responded to by the selected participants and key informants in the scheme. Qualitative and quantitative methods were used to obtain the responses from the scheme participants and the data processed using SPSS.
Based on the analysis of respondents‟ perceptions of the farmers, the study concludes that RESIS is perceived to have had a positive impact on the livelihoods of the beneficiaries. Gross margin analysis supports the farmers‟ perceptions.

The livelihood impacts of commercialization in emerging small-scale irrigation schemes in the Olifants catchment area of South Africa.Tapela, Barbara Nompumelelo January 2012 (has links)
Philosophiae Doctor - PhD / This thesis examines livelihoods in the wake of agricultural commercialization under the Revitalization of Smallholder Irrigation Schemes (RESIS) Programme and similar revitalization initiatives within the Olifants River Basin in Limpopo Province. The focus is on contractual joint ventures and strategic partnerships implemented within selected smallholder irrigation schemes. The thesis is based primarily on in-depth empirical studies conducted between October 2003 and March 2009 in three sites located in two Integrated Sustainable Rural Development Programme (ISRDP) poverty nodes namely, Greater Sekhukhune and Vhembe Districts. To a lesser extent, the thesis draws on findings from rapid appraisals of five additional study sites in Greater Sekhukhune District. Research findings showed that the performance of joint ventures and strategic partnerships had so far largely fallen short of expectations. With the exception of a minority of smallholders involved in RESIS-Recharge strategic partnerships, the promise of higher incomes and improved livelihoods had often remained elusive, while debts and potential losses of often meagre household assets loomed large, threatening to erode existing livelihoods and undermine government interventions. This was mainly because ‘viability’ in both the RESIS and RESIS-Recharge phases was narrowly seen in economic and technical terms, such that reduction of transaction costs often entailed the divesting of responsibilities to address issues of rural poverty and inequality. Subsistence production had largely given way to commercially-orientated farming, and weak monitoring of contract formulation and implementation meant that voices of marginalized poor and vulnerable people, particularly women and the elderly, were not being heard. Research findings further revealed that while RESIS-Recharge strategic partnerships increased incomes for a minority of smallholders, such arrangements did not meaningfully improve the productive, managerial and marketing skills of smallholders to ensure their effective participation in agriculture. Rather, strategic partnerships were creating a small class of black ‘arm-chair’ farmers, who played little or no active role and obtained few or no skills in commercial farming but perpetually depended upon and drew incomes from agribusiness initiatives run by externally-based agents. Adjunct to questions of sustainability for these farmers’ ability to participate in commercial farming, the thesis raises the question: What is the rationale for joint ventures and strategic partnerships in the context of South Africa’s Agricultural Sector Strategy objectives for support to black farmers? Contracts lacked mechanisms for equitable distribution of costs and benefits between contracted private partners and targeted smallholders, on the one hand, and the rest of members of local communities, on the other hand. Contracts also lacked provisions for postproject recapitalization of infrastructure and rehabilitation of degraded land. This raised questions about the longer term sustainability of productivity, natural resource base and livelihood security in smallholder irrigation schemes. The conclusion of this thesis is that the challenge of reducing rural poverty and inequality in smallholder irrigation schemes might not be resolved through existing institutional approaches to agricultural commercialization.

The impact of smallholder irrigation schemes on job creation :The case of Mabunda, Seloane and Mariveni Irrigation Schemes, Mopani District, Limpopo ProvinceSambo, Famanda Thomas January 2014 (has links)
Thesis (M.Sc. (Agriculture)) -- University of Limpopo, 2014 / The study was designed to establish the impact of irrigation schemes on job creation and also from the jobs created to differentiate permanent from temporary jobs. The focus of the study was on three smallholder irrigation schemes (Mabunda, Mariveni and Seloane, the irrigation schemes are located in Greater Giyani, Greater Tzaneen and Ba- Phalaborwa municipalities respectively). For the purpose of the study, Mabunda will be addressed as scheme 1, Mariveni as Scheme 2 and Seloane will be addressed as Scheme 3.The main crops cultivated in the three irrigation schemes are citrus, coupled with vegetables to generate funds when citrus is out of season.
The study employed a case study approach and used both qualitative and quantitative methods to collect data. The study was implemented in two phases: the first phase focused on irrigation scheme participants, while the second phase focused on the community structures (livestock committee, youth, water committee and tribal council) that have been affected by the establishment of the irrigation schemes. Data was collected from the irrigation schemes beneficiaries and community structures by means of a structured questionnaire. No random selection method was used in the selection of irrigation scheme beneficiaries. This was influenced by the small number of beneficiaries in the three schemes (56).It was only the community structures that were randomly selected. One hundred and five (105) people were interviewed representing different structures in all three villages. Out of this figure thirty five(35) people were interviewed per village. Data collected was organized into themes for analysis. Data was analyzed manually, where the coded questionnaires were recorded into a spread sheet. The process of analysis was carried out by using qualitative description and descriptive statistics. Data was manually analysed and the output was discussed using tabulation and cross-tabulation of variables with percentages in descriptive statistics. From the spread sheet data was summarized manually. For the period 2006 to 2009, the irrigation schemes anticipated to create 42 permanent job opportunities with the exception of 2006 where the projected jobs were 32. For the same period, the following temporary job opportunities were anticipated: 121 in 2006,236 in 2008, 240 in 2010, 234 in 2012,233 in 2014 and 232 in 2016. The irrigation schemes also anticipated to inject the monetary value into the community in the form of basic salaries. In 2006, R839,996.76 was injected into the community in the form of salaries, 2008 – R1,509,060.33, 2010 – R1,775,531.58,from 2012 – 2018. R2,045,130.36, R2,381,396.14 and R2,772,145.45 injected into the community respectively, while the divisional management team were expected to receive, R27,525, R36,800, R35,920, R43,857 and R54,118 in the form of performance bonuses, in 2008, 2010, 2012, 2014 and 2016 respectively.
The actual permanent jobs created for the period 2005 to 2009 in Scheme 1, an average of 64.6 (the anticipated was 42), while the actual temporary jobs created averaged 395. Scheme 2, managed to create an average of 86 permanent jobs and 197 temporary jobs, while the anticipated was 42 and 240 respectively. In Scheme 3, averages of 74 permanent jobs were created while 55.4 temporary jobs were created. The irrigation schemes created more jobs than anticipated. This was influenced by the high rate of unemployment in the villages located next to the irrigation schemes and the irrigation schemes as the only job providers closer to the villages.
Temporary workers are paid performance based salaries. For the period 2005 to 2009, they were paid as follows: in 2005, they were paid R0.35 per bag of oranges harvested. The actual salary earned per month was informed by the number of bags harvested for that particular month. The following years the salary
was increased by five cent per bag. Permanent workers were paid an average salary of R2400.00 per month.
The study recommended that the roads leading to the three irrigation schemes should be maintained to minimize fruit damage during transportation to the market. The schemes should also be financially assisted to acquire own farm equipment (tractors, trailers and trucks) and be trained on the maintenance of these equipment to reduce acquiring services from the private service providers. The three irrigation schemes use private transport to carry their produce to the market and they are charged for this service, hence, the acquisition of own transport is necessary.

Investigation of the economics of water as used by smallholder irrigation farmers in South AfricaYokwe, Stanley Conficious Bartholomew 06 February 2006 (has links)
This study investigates the economics of water as used by smallholder irrigation farmers in South Africa. The productivity and value of water were estimated with data from two smallholder irrigation schemes: Zanyokwe and Thabina. Production parameters such as fertilisers, seeds, pesticides, equipment, transport, labour, and water were treated as inputs. Various methodologies used to estimate water value, including cost-based approaches, were thoroughly reviewed. The aim was to select the ones with more justification for use in smallholder irrigation sector and also to compare a number of approaches. On a case study basis, three methods were applied: residual valuation method, willingness to pay and cost-based approaches (i.e. accounting costs of O&M). Water productivity and values were then evaluated as per crop, farmer, and scheme. Also, cross-section regression analysis was used to investigate the effect of some key socio-economic factors of production on gross margin and willingness to pay. The results indicated that on average, the value of water varies according to methods, crops, farmers and schemes. In the Zanyokwe scheme, water value estimated by the residual method in cabbage is higher (R1.64 per m3) than the one in dry maize (R0.35 per m3), if intensive and high yield irrigated crops are grown per year. Also, in Thabina, water value for cabbage (R1.14 per m3) outperforms water value for dry maize (R0.02 per m3. This means that there is greater potential in vegetable crops than food grain crops, although the two schemes have different irrigation systems, and such analysis is based on one-year data, which may lack accuracy. Low water valuation is ascribed to low yield and extensive cropping systems, because gross margin per hectare is very low. This signifies the need for expansion in high value crops rather than low value crops. At farm and scheme level, the results were derived by using the Smile database and simulated platform. The Smile platform is a data capturing and a calculation tool. It calculates a number of indicators, economic figures, at scheme and individual farm level, allowing for evaluation of the current situation. The results suggested that at present, the Zanyokwe scheme requires about 1 739 255 m3 of irrigation water per year. The total operational costs (accounting costs of O&M) are about R146 097.42. In other words, supplying 1 m3at farm level will cost R0.084. This implies that if irrigation charges are levied so as to cover O&M costs of the Zanyokwe scheme, the current costs (R0.084) will form only 23% of the average gross margin of R0.37 per m3 used at scheme level. Furthermore, in the Zanyokwe irrigation scheme, the results revealed that the most active and efficient farmers (specialized farmers) can make an average gross margin of R4 105 per ha per year, also achieving the highest water productivity R0.69 in gross margin per m3 consumed. However, in the Thabina scheme, the results indicated that, to supply 1 m3will cost R0.062. Thus, the current water supply costs cover about 56 % of what is earned (i.e. R0.11 per m3 used) at scheme level. Again, the most active farmers (commercially oriented pensioners) are more efficient, with average gross margin of R3 092 per ha per year, also achieving the highest water productivity (R0.53 in gross margin per m3 used). These results suggested that certain smallholder farming systems seem capable of paying for irrigation charges of their respective schemes if they are obliged to do so. As far as willingness to pay (WTP) and cost-based approaches (CBA) are concerned, the results clearly show that the active farmers in the Zanyokwe scheme have lower WTP per m3 (R0.03) than the GM of output (R0.69) per m3 of water used. Also, the accounting cost (R0.084 per m3 of water used) is lower than the GM gained. However, in the Thabina scheme, the situation is quite different. The active farmers are willing to pay R0.19 per m3 of water used. This implies that, if farmers are to pay for the charges in order to cover O&M costs, the farmers in Thabina are ready to pay as much as three times the proposed costs of O&M (R0.062 per m3 of water used), although both the WTP and the accounting cost are lower than GM gained. In these results, it is significant that both the accounting cost and the willingness to pay are lower than the GM per m3 of water used at least in the Zanyokwe scheme. Even though the data were drawn from a sample for one year only, this finding on the perception of farmers has implications for extension and training to improve future productive use. Regarding the findings from cross-section regression analysis, the results for GM (as dependent variable) in general indicated that in the Zanyokwe scheme, only credit affects output positively and significantly. Production costs have significant effect on output, but with a negative correlation. It is striking that all the other factors of production including hired labour show negative and insignificant effects on output. In the Thabina scheme, the most important factors of production in the model are land size (hectare) and production costs (Rand per ha). These two variables influence output positively and significantly. As far as WTP (as dependent variable) is concerned, the results indicated that in the Zanyokwe scheme, it is striking that in all the investigated factors, only credit affects WTP positively and significantly. All other factors are insignificant. Also, gross margin of output per m3, unexpectedly, has displayed a negative and insignificant effect on output. In the Thabina scheme, the results show that the land size per hectare, and gross margin of output per m3 affect WTP positively and significantly. Such results are consistent with the assumptions made in the conceptual framework that a farmer with high gross margin gained at farm level is more likely to pay for water costs than those with poor gross margin. On the basis of these findings, the following recommendations were formulated. Specific policies should include promotion of high value crops and improved varieties of seed for food grain crops (e.g. maize) and vegetables (e.g. cabbage). While improved agronomic practices remain important, there is also potential to increase productivity and profitability of the crops by improving water management practices at the canal-system level, such as better timing of water delivery and increased overall canal-water supplies at the farm level. Finally, from a cost recovery point of view, government should develop a program of cost sharing for capital costs of irrigation development. With regard to inter-sectoral competition, these results highlight that, if inter-sectoral competition is left to uncontrolled market forces may result in smallholder farmers' selling their water rights to sectors which value water at higher levels. To avoid a “liberal trap” such as in the example of Chile (where smallholder farmers "en masse" sold their water rights, resulting ultimately in deeper rural poverty), some form of control/management of water rights transaction involving smallholder farmers is necessary. Finally, the findings of this study can be used in various ways. Since, these values determine the farmer’s ability to pay for water now or in the future, the incentive to use water judiciously will be governed by these values. Secondly, the results can be used to evaluate whether the costs estimated and gross margin per m3 gained at farm level, are in line with the farmers’ willingness to pay. Further work is recommended to clarify these conclusions and provide more policy clarification on the better use of water by smallholder irrigation farmers in South Africa. / Dissertation (MInst.Agrar)--University of Pretoria, 2007. / Agricultural Economics, Extension and Rural Development / unrestricted

East African Hydropatriarchies : An analysis of changing waterscapes in smallholder irrigation farmingCaretta, Martina Angela January 2015 (has links)
This thesis examines the local waterscapes of two smallholder irrigation farming systems in the dry lands of East African in a context of socio-ecological changes. It focuses on three aspects: institutional arrangements, gender relations and landscape investments. This thesis is based on a reflexive analysis of cross-cultural, cross-language research, particularly focusing on the role of field assistants and interpreters, and on member checking as a method to ensure validity. Flexible irrigation infrastructure in Sibou, Kenya, and Engaruka, Tanzania, allow farmers to shift the course of water and to extend or reduce the area cultivated depending on seasonal rainfall patterns. Water conflicts are avoided through a decentralized common property management system. Water rights are continuously renegotiated depending on water supply. Water is seen as a common good the management of which is guided by mutual understanding to prevent conflicts through participation and shared information about water rights. However, participation in water management is a privilege that is endowed mostly to men. Strict patriarchal norms regulate control over water and practically exclude women from irrigation management. The control over water usage for productive means is a manifestation of masculinity. The same gender bias has emerged in recent decades as men have increased their engagement in agriculture by cultivating crops for sale. Women, because of their subordinated position, cannot take advantage of the recent livelihood diversification. Rather, the cultivation of horticultural products for sale has increased the workload for women who already farm most food crops for family consumption. In addition, they now have to weed and harvest the commercial crops that their husbands sell for profit. This agricultural gender divide is mirrored in men´s and women´s response to increased climate variability. Women intercrop as a risk adverting strategy, while men sow more rounds of crops for sale when the rain allows for it. Additionally, while discursively underestimated by men, women´s assistance is materially fundamental to maintaining of the irrigation infrastructure and to ensuring the soil fertility that makes the cultivation of crops for sale possible. In sum, this thesis highlights the adaptation potentials of contemporary smallholder irrigation systems through local common property regimes that, while not inclusive towards women, avoid conflicts generated by shifting water supply and increased climate variability. To be able to assess the success and viability of irrigation systems, research must be carried out at a local level. By studying how local water management works, how conflicts are adverted through common property regimes and how these systems adapt to socio-ecological changes, this thesis provides insights that are important both for the planning of current irrigation schemes and the rehabilitation or the extension of older systems. By investigating the factors behind the consistent marginalization of women from water management and their subordinated role in agricultural production, this study also cautions against the reproduction of these discriminatory norms in the planning of irrigation projects. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 4: Manuscript.</p><p> </p>

The impact of smallholder irrigation schemes on poverty reduction among rural households of Vhembe and Sekhukhune Districts in Limpopo Province, South AfricaBaloi, Vutomi Arone January 2022 (has links)
Thesis (Ph.D. Agriculture. (Agricultural Economics)) -- University of Limpopo, 2022 / Many researchers in different parts of the world have advocated the use of irrigation water to reduce levels of poverty, especially among rural households. This is made possible through the development of irrigation schemes in these areas and giving the necessary support to these farmers. If this is done sufficiently, irrigation schemes` participants are sure to realise improved livelihoods and poverty reduction.
However, different communities are faced with different challenges and are subjected to rules and norms applied in their respective communities. On one hand, farmers are individuals who also have personal beliefs and characteristics that may be critical in determining the success of their irrigation schemes. On the other hand, certain characteristics (e.g., unequal distribution of water and land) can be inherited as challenges by farmers in such communities, making it difficult to overcome and thus posing threats to the success of irrigation schemes.
A purposive-multistage technique together with a simple random sampling were used to sample 300 smallholder farmers from the Vhembe and Sekhukhune districts of Limpopo Province. An analysis of data was done using a combination of analytic techniques such as the Binomial Logit, Principal Component Analysis, Multiple Regression Analysis, Poverty Indices and the Women Empowerment Agriculture Index. The latter was employed to examine whether or not there are efforts by the irrigation schemes to empower women. The main aim was to analyse the contribution and impact that irrigations schemes have on poverty reduction among smallholder farmers. There was also a need to consider the role that positive psychological capital may play in uplifting the hope, confidence, resilience and optimism by farmers in their irrigation schemes.
The results revealed that women’s participation was high (58%) in the irrigation schemes as compared to men. However, this did not mean that women were empowered automatically. After administering the Women Empowerment Agriculture Index, it was found that women are actually disempowered in three (out of five) indicators that were used as a measure of empowerment. Meanwhile, most farmers who used irrigation, saw their livelihoods improve and their poverty status improve too. Irrigation was able to increase their yields, incomes, employment, and other household assets. It was again proven that positive psychological capital played a significant role in reducing poverty. However, factors such as lack of capital assets, social grants, illiteracy, old age, lack of vocational training and risk aversion in some instances contributed to poverty.
In order to enhance the livelihoods of smallholder farmers, the government and other relevant bodies should see to it that agricultural extension services are improved and include vocational training for these farmers together with the provision of market information and business training. This may help farmers realise the importance of farming as a business and not relying on government for everything they need. A larger share of income for most farmers came from social grants and remittances. This is likely to have a negative impact on the success of irrigation schemes. Therefore, farmers need to be trained for self-reliance. The need to promote women’s participation in decision-making for water management and also suggests ways in which women’s access to water can be improved through equitable development cannot be overemphasised. There is also a need to conduct a study on the measurement and role of psychological capital in rural livelihoods using other methods such as revealed preference approach, experimental economics and behavioural economics.

Comparative engineering costing and implications of commercial and smallholder irrigator design for projectsHards, Adrian F. 03 1900 (has links)
Thesis (MScEng (Civil Engineering))--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: In the study, six irrigation schemes based in the Eastern Cape have been
considered and evaluated, according to two levels of supply (LOS) of irrigation
water. The two levels of supply are that of a commercial irrigator and that of a
smallholder irrigator. The irrigation infrastructure for each of the six schemes
was designed, and the associated costs determined, for each level of supply.
The primary objective of the study is to determine the impact of infrastructure
costs and irrigation areas on the target user, either the commercial or the
smallholder irrigator. This is related directly to the assumption that lower water
volumes are used by the smallholder irrigator.
The study addresses the impact of different designs on the amount of water
used, land utilised and resultant costs of the infrastructure.
The initial capital costs and the on-going operational and maintenance costs
(O&M) for each level of supply for each of the schemes have been calculated.
The evaluation of the two LOS has shown that the capital cost for the
commercial LOS is approximately 18 % higher than for the smallholder LOS
and the O&M costs 6 % to 36 % higher.
The schemes that were investigated can be grouped into five general scheme
types. The first type is gravity schemes, which need rehabilitation, while the bulk
supply is in place with no augmentation or rehabilitation required. The second is
pumped scheme which is in need of rehabilitation, while the bulk supply is in
place with no augmentation or rehabilitation required. The third type includes
run-of-river schemes where water is abstracted and pumped directly to the
lands. The fourth type includes run-of-river schemes where water is abstracted
and pumped to storage. The fifth type is the gravity scheme where the bulk
supply needs to be installed as part of the scheme. These types are then
grouped and can be used to give guidance on the anticipated costs dependant
on the scheme type and the required level of service. A further objective of the research is to determine the impact on the smallholder
irrigators who find themselves on a commercial LOS system. This can be either
on a scheme that has already been designed, or on a new system.
The evaluation of the commercial under-utilised LOS and the smallholder LOS
has shown that the commercial capital cost is 18 % higher and the O&M costs
5 % to 29 % higher.
The study further aligns the estimated costs with the farmer typology providing a
broader understanding of the design to be adopted for different levels of supply.
This provides the linkage between farmer types, the design to be implemented
and the anticipated costs thereof. / AFRIKAANSE OPSOMMING: As deel van hierdie narvorsing word ses verskillende besproeiingsskemas in die
Oos-Kaap ten opsigte van twee voorsieningsvlakke ondersoek. Die twee
voorsieningsvlakke ter sprake is vir ‘n kommersiële en kleinboerdery opset. Die
besproeiingsinfrastruktuur is vir elk van die ses besproeiingsskemas ontwerp en
‘n kosteberaming vir elk van voorsieningsvlakke gedoen.
Die hoofdoelwit van hierdie verslag is om te bepaal wat die impak van kostes en
besproeiingsareas op beide kommersiële- en kleinboerderye is. Dit is direk
gebaseer op die aanname dat kleinboerderye minder water gebruik.
Die verslag ondersoek die impak van verskillende ontwerpe op waterverbruik,
besproeiingsoppervlak benodig en die gevolglike infrastruktuurkostes.
Die aanvanklike kapitaalkostes asook bedryfs- en onderhoudsuitgawes (B&O)
vir elk van die voorsieningsvlakke, is vir elk van die besproeiingskemas
bereken. Die resultaat van die ondersoek van die twee voorsieningsvlakke het
aangetoon dat die kapitaalkoste van kommersiële besproeiingskemas 18 %
hoër as die van kleinboerderye is, en bedryfs- en onderhoudsuitgawes 6 tot 36
% hoër.
Die skemas wat ondersoek is, kan in vyf algemene skema tipes verdeel word.
Die eerste is die gravitasieskemas wat rehabilitasie benodig terwyl die
hooftoevoer in plek is met geen uitbreidings- of rehabilitasiebehoeftes. Die
tweede is pompskemas wat rehabilitasie benodig terwyl die hooftoevoer in plek
is met geen uitbreidings- of rehabilitasiebehoeftes. Die derde is rivierskemas
waar besproeiingswater direk uit die rivier na die landerye gepomp word. Die
vierde is rivierskemas waar besproeiingswater direk uit die rivier na a reservoir
gepomp word. Die vyfde skema tipe is die gravitasieskemas waar die
hooftoevoer ook gebou moet word as deel van die skema. Die skema tipes kan
gebruik word om leiding te verskaf ten opsigte van verwagte skema kostes
afhangende van die skema tipe en vereiste voorsieningsvlak. ‘n Verdere doelwit van die studie is om die impak op kleinboere te bepaal wat
op ‘n kommeriële voorsieningsvlak boer. So ‘n stelsel kan ‘n gevestigde of nuwe
stelsel wees.
Die resultaat van die ondersoek van die onderbenutte kommersiële
voorsieningsvlak en die kleinboerdery voorsieningsvlak het gewys dat die
kapitaalkoste van kommersiële besproeiingskemas 18 % hoër as die van
kleinboerderye is, en bedryfs- en onderhoudsuitgawes 5 tot 29 % hoër.
