Applications of land information systems in land re-adjustment projects : "Lesotho experience".
(2001) Mothunts'ane, Bophelo.; Chilufya, Sexton Mwitwa.
Land information is a an important resource in planning, and in undertaking land administration functions such as allocation of interests to land, land adjudication, land valuation, physical planning, etc. Rapid urbanization, however, puts great pressure on personnel delegated to undertake these functions. The personnel can no longer cope with capturing, processing and disseminating land information for the increasing urban population. Observing the failures of land information management to cope with rapid urbanization, the researcher undertook an exploration into the capabilities of LIS to manage land informatioo for The Millennium Park Land Development Project (MPLDP) in Maseru, the Lesotho capital. The project is based on land readjustment principles and is of mulli-stakeholdership. Such big and networked projects have been shown to be associated with land information management problems. Undertaking this research was motivated by many success stories however, world wide, in which LIS was introduced as a tool to assist in land information management. The main themes in this project are firstly, the study of Land re-adjustment as a land management technique to meet land demand for urbanization and secondly land information system as a tool to manage land information for a land re-adjustment project. Study of LR will help understand what land information is required for such a land management project. Study of land information system will help exploring its capabilities that can be applied to manage land in formation for LR projects. Furthermore, as a case study to this, the MPLDP system is analysed. examining the activities and ways in which land information is managed. This analysis is aimed at identifying the constraints that result in the observed back logs in the project activities; and recommending improvements. Many problems and constraints are identified in the MPLDP. As a land surveyor, only improvements related to technical constraints are considered in this research, with cognizance of the legal and institutional issues that need to be addressed in implementation of these improvements. The main improvement discussed is the creation of automated databases and illustrations are given on how these databases could be used to manage land information effectively for the MPLDP.
Evaluation of largis application in planning, acquisition and maintenance of utility servitudes : an Eskom case study.
(2016) Monamane, Ntombizodwa A.; Chilufya, Sexton Mwitwa.; Musonda, E.; Akombelwa, Mulemwa.
GIS has been used for quite some time by utility organisations while the demands for their services by the public have also increased exponentially. This has prompted many utility organisations to constantly review their systems in operation for any potential problems associated with their use in order to propose possible and suitable improvements necessary to maximize their production. This study evaluates the performance of Land and Rights Geographic Information System (LARGIS), a GIS based information management system employed by Eskom to manage its servitudes’ land rights information. LARGIS has been analysed in terms of its application to planning, acquisition, registration and maintenance of servitudes land rights information. Information on LARGIS was collected using a questionnaire administered to Eskom personnel that work with the system while interviews were used to obtain more information not obtainable from the questionnaire. Obtained information was analysed using a relational matrix of data sets and processes in order to identify subsystems making up LARGIS. Information flows and processes in each of the subsystems were then analysed using Data Flow Diagrams (DFD) supported by associated Data Dictionary (DD) so as to identify possible shortcomings in information flows and information processing. The information collected was also used to identify institutional, legal, economic and additional technical shortcomings. The study revealed that LARGIS had made a positive impact on the way Eskom previously managed its servitudes by using a single system to plan, acquire, register and maintain land rights associated with servitudes. However, the study also identified shortcomings for which recommendation have been proposed so as to make LARGIS much more responsive to Eskom`s demands for servitudes land rights information management.
Exploring the spatial expansion of settlements in customary regions : a case study of Adams rural, KwaZulu-Natal.
(2015) Dlamini, Siboniso Msinsi.; Akombelwa, Mulemwa.; Chilufya, Sexton Mwitwa.
Adams Rural is one of KwaZulu-Natal’s customary regions which falls under the traditional boundaries of the Ingonyama Trust Board. In this rural area traditional customs are still being practiced. The major land use was previously dominated by agriculture and very few residential settlements. This study reflects on the increasing recognition of the expansion of human settlements in this customary region. The expansion of human settlements is observed to have increased over the past decade and is confirmed by annual aerial imagery of the area captured by the eThekwini Municipality. The historical images captured by the National Geo-Spatial Information (NGI) suggest that there has been a substantial land use change in the area, resulting in loss of land previously used for sugarcane plantation. Therefore the study utilised spatial analytic techniques to quantify spatial changes in Adams Rural and map the land use / land cover change between years 2001-2004, 2004-2006, 2006-2008, 2008-2010 and 2010-2012 in Adams Rural. The research employs a post-classification change detection technique performed on selected orthophoto imagery, to assess spatial change patterns, to quantify the amount and the rate of change in human settlements of Adams Rural during the period 2001 to 2012. The results show that spatial extent of human settlements has more than doubled with commensurate loss in agriculture. Demographic data for 2001 and 2011 obtained from Statistics South Africa (Statistics SA, 2001 and 2011) also confirms that the population of the area has more than doubled over the same period. The rate of increase in settlements varied between periods considered with the population increasing proportionately. A closer inspection of the area was conducted using a questionnaire administered to the community. The questionnaire shows that the major contributor to the population increase in the area is the majority of people relocating from urban areas to this customary region. The questionnaire results further show that people are attracted to the development occurring in the area, larger parcels extent and the low cost of living with no bond payments, as there are no property rates payable on customary land. An attempt was made to project the spatial growth of built-up areas over the next 10 years using the change rate obtained from change detection verifying the prediction using the results from a questionnaire survey of the residents in the study area. It is observed that change by 2022 may likely follow the trend in 2001-2012. The present study shows that spatial analysis based on land use mapping using orthophoto imagery is very effective in monitoring the spatial features in customary regions.
A framework for applying spatial decision support systems in land use planning.
(2002) Peacock, Peter Graham.; Chilufya, Sexton Mwitwa.; Fourie, Clarissa.
For local authorities to manage land policies effectively data bases of land use information that are current and mirror development on the ground are required. At present local authorities have no mechanisms in place to acquire maintain and spatially link land use information. Detailed land use information is not generally available at the local level. Generally little attention is paid to maintaining the expensive data which is assembled when planning schemes, development plans or projects are prepared. Land use planning has traditionally focussed on the control rather than the facilitation of development. Details of the actual land use on the ground are generally ignored as tariffs for tax purposes are set on the zoning of the land or a flat rate rather than the actual land use. This lack of land use information, which is exacerbated by informal settlement, causes delays in approving new land uses. There is generally no data available for informal areas and land use and tenure is subject to the informal rules that have evolved with such settlements. If these areas are to be included in the formal land management systems, ways of including and maintaining land use information about these settlements must be developed. By reviewing land information theory, the South African legal land development framework and using a small town as a case study, I have shown that provided certain conditions are met a Spatial Decision Support System (SDSS), designed to record and maintain the land use data necessary to support land use planning in both formal and informal contexts, could be a valuable land management tool. Such a system should be implemented in partnership with local communities and should; • support local level land use decision making and regulation • serve as a land management tool to integrate formal and informal communities • have mechanisms to keep land use information current • be transparent about the type of land use information • develop linkages with regional government to provide detailed land information over time.
Investigating the feasibility of establishing a South African marine cadastre.
(2015) Reddy, Kovilen.; Akombelwa, Mulemwa.; Chilufya, Sexton Mwitwa.
Human interaction with the marine environment is increasing at a rate at which marine management systems cannot keep pace. The land cadastral systems are deemed to be well-established and understood thanks to hundreds of years of development. Meanwhile, as marine technological innovations advance and population density in coastal areas grows, human interaction with the oceans is evolving, making existing systems in place for their management seem out-dated. In South Africa, the declaration of Project Phakisa to unlock the oceans economy, which has been relatively untouched, acknowledges the potential benefits that can be extracted from the sea. A land cadastral system consists of graphically depicted boundaries that have been surveyed, and a register that assigns any rights, restrictions and responsibilities to the area enclosed by such surveyed boundaries. Management of marine property rights is not dissimilar to the land cadastre insofar as there being parallel survey and registry components. Internationally, marine cadastre initiatives are being researched and implemented to update marine management systems while there is recognition for convergence of land and sea based spatial data infrastructures. This study explores the need for the development of a seamless cadastre across the land-sea interface for South Africa by assessing the perceptions of stakeholders that deal in land and/or marine environments. The study investigates access to land versus marine spatial data, legal and technical aspects, components and features of a possible marine cadastre. By adopting a case study strategy using both qualitative and quantitative inquiry approaches, the rendered results presented later in the dissertation have increased reliability resulting from the processes of data triangulation. The main findings indicate that the spatial and accompanying registration component of the land-based cadastral system is sufficient to form the cornerstone of land administration in SA. The literature review and canvassing of persons related to the geospatial fraternity indicates, via analysis of a questionnaire and interviews, shortcomings in good ocean governance. Although a marine cadastral system is feasible for SA, it is beset with spatial, technical, legislative and institutional issues that need ironing out. The unification of the land and possible marine cadastral systems would enable a single land-sea spatial data infrastructure that would mute the effects of an uncertain land-sea interface.
