Full textThis study investigated the land-use potential of the Liesbeeck-Black River confluence area . It is intended to serve as a guide to land-use planners and other interested parties concerning the opportunities and constraints proffered by the environment on the confluence area. The collecting of baseline data was undertaken by nine Masters Students in the Department of Environmental and Geographical Science at the University of Cape Town. Each student then analysed the data individually. The study was undertaken in part fulfilment of the academic requirements of the Masters Degree. The Liesbeeck-Black River confluence area (hereafter called the study area) is located approximately 5.5 km east of the CBD of Cape Town. It covers approximately 232 ha and is bounded by the N2 Freeway to the South, Alexandra Road to the East, Liesbeeck Parkway to the West and the Culemborg-Black River Railway Yard to the North. The aim of the study was twofold, firstly to determine a procedure whereby the optimal land- use alternative for an area could be determined, taking into account the effects of significant environmental elements, and secondly to analyse and determine the optimal land-use alternative for the study area specifically. The procedure developed during the research is an adaptation of the Leopold Matrix method of analysis. The environmental elements characteristic of the study area are listed on the horizontal axis, and the land-use options to be analysed on the vertical axis. The magnitude and significance of the effect of an environmental element on a particular type of land-use can then be rated and this rating entered in the corresponding matrix cell. By adding the ratings of all environmental elements on each land-use option, the overall rating of the different land-use options can be obtained. The option with the highest overall (positive) rating is then considered to be the optimal type of land-use. This method was then applied to assess the land-use potential of the study area. The land-use options considered to be appropriate for the study area were determined by considering only those types of land-uses for which a regional need had previously been established.

Full textENGLISH ABSTRACT: In many developing countries, rapid urbanisation continues to substantially transform land from agricultural and rural land uses, as well as natural landscapes into urban areas. This leads to significant changes to the socio-economic fabric and nature of the natural environment. Data to monitor such transformation is often out of date, unreliable, in unstandardised format, cumbersome and expensive to collect or simply unavailable in urban centres of many developing countries. These characteristics inhibit local authorities‘ and other stakeholders‘ capacity to monitor and leverage resources toward sustainable urban development. Sustainable urban land use planning is a major objective of urban planning, but it is difficult to put into practice. This study investigates the efficacy of earth observation (EO) for collecting information required for sustainable urban land use planning and proposes the use of decision consequence analysis (DCA) as a simple and structured way to put sustainable urban development into practice. The study focuses on three central determinants of sustainable urban land use, namely (1) land use change and land use mix, (2) urban sprawl and (3) the urban built-up area. Consequently, urban sustainability indicators of these three components were identified. EO data for Stellenbosch, a town in the Western Cape province of South Africa, was gathered and used to perform spatio-temporal analyses of the indicators in a geographic information system (GIS). This enabled the establishing of the positive or negative trajectory made toward achieving sustainable urban land use planning. The study demonstrates how the use of EO data, DCA, urban sustainability indicators and GIS can enhance local authorities‘ capacities for monitoring urban sustainability. EO data and urban sustainability indicators were used to develop an urban sustainability toolbox which facilitates evidence-based decision making. The results also show that urban sustainability indicators derived from EO are valuable in providing synoptic, up-to-date, standardised and normalised information on urban areas. Such information would be expensive and cumbersome to collect without the use of EO and GIS. As a result, earth observation will continue to play a key role in monitoring urban sustainability, particularly in developing countries.
AFRIKAANSE OPSOMMING: Die volgehoue en versnelde verstedeliking wat in baie ontwikkelende lande voorkom is voortdurend besig om landbougrond, plattelandse gebiede en natuurlike landskappe na stedelike areas om te skakel. Dit bring ʼn noemenswaardige verandering in die sosiaal-ekonomiese struktuur en aard van die natuurlike omgewing te wee. Data om hierdie veranderinge te monitor, is dikwels verouderd, onbetroubaar, nie in ʼn standaard formaat nie, omslagtig, te duur om te in te samel of net eenvoudig nie beskikbaar vir baie stedelike sentra van ontwikkelende lande nie. Hierdie faktore beperk plaaslike owerhede en ander belanghebbendes se moniteringskapasiteit en verhinder die beskikbaarstelling van hulpbronne vir volhoubare stedelike ontwikkeling. Beplanning vir volhoubare stedelike grondgebruik is ʼn belanrike doelwit, maar is moeilik om in die praktyk toe te pas. Hierdie studie ondersoek die doeltreffendheid van aardwaarneming (AW) vir die insamel van inligting wat vir volhoubare grondgebruik beplanning nodig is. Die studie stel die gebruik van analise van besluitnemingsgevolge (ABG) as ʼn eenvoudige en gestruktureerde manier voor om volhoubare stedelike ontwikkeling in die praktyk toe te pas. Die ondersoek fokus op drie hoof bepalende faktore van volhoubare stedelike grondgebruik, naamlik (1) verandering en vermenging van grondgebruik, (2) stedelike kruip, en (3) die beboude stedelike gebied. Gevolglik is aanwysers van die stedelike volhoubaarheid van hierdie drie komponente geïdentifiseer. AW-data vir Stellenbosch, 'n dorp in die Wes-Kaap provinsie van Suid-Afrika, is ingesamel om met behulp van ʼn geografiese inligtingstelsel (GIS) die aanwysers tyd-ruimtelik te analiseer. Dit het dit moontlik gemaak om die positiewe of negatiewe trajekte vir die bereiking van volhoubare stedelike grondgebruiksbeplanning vas te stel. Die studie demonstreer hoe AW-data, ABG, aanwysers van stedelike volhoubaarheid en GIS plaaslike owerhede se kapasiteit vir die monitering van volhoubaarheid in stede kan bevorder. AW-data en stedelike volhoubaarheidsaanwysers is gebruik om 'n stedelike volhoubaarheidsgereedskapkis te ontwikkel wat bewysgebaseerde besluitneming fasiliteer. Die resultate wys ook dat volhoubare stedelike aanwysers afgelei uit AW, nuttig is om sinoptiese, gestandardiseerde en genormaliseerde inligting oor stedelike gebiede te voorsien. Hierdie tipe inligting is duur en omslagtig om in te samel sonder die gebruik van AW en GIS. Gevolglik sal AW voortaan steeds 'n sleutelrol speel in die monitering van stedelike volhoubaarheid, veral in ontwikellende lande.

Full textA positive correlation was found between independent estimates of the density of males and counts of red-wings obtained from the North American breeding bird survey (BBS). Density of males was a useful indicator of the number of red-wings in an area, whereas the BBS was a useful indicator of change in regional population level.
Historical increases in populations of red-wings in these regions were correlated with increases in waste grain (corn) following harvest. Greater rates of population increase in Quebec (compared with Ontario) corresponded to higher rates of increase in waste corn abundance and landscape heterogeneity. In Quebec, cultivation (mainly corn) was the most important habitat influencing density of males. Wetland and hay field abundance were also important. Heterogeneous landscapes incorporating crops, wetlands and hay fields attracted the most male red-wings regardless of population level, and breeding males preferred wetlands and hay fields for territory establishment. Fields were used in proportion to abundance, whereas forest, crops and areas of human occupation were avoided. At high population density, proportionately more males settled in areas of human occupation and in fields; these habitats were less suitable than wetlands or hay fields. Packing of males into a preferred hay field habitat occurred.
Overwinter mortality did not favor small body size in male red-wings but evidence of stabilizing selection on female body size was found. Sexual dimorphism was slightly more pronounced in spring than in fall. Historical changes in the body size of red-wings were not clearly related to increasing abundance of food (corn). If population size tracks increases in food abundance, then inter-male competition for breeding space may intensity; thus, large size may be limited by energy contraints imposed on males by sexual selection pressure regardless of food availability.

Full textThis dissertation aims to evaluate the environmental factors within the Liesbeeck and Black River Confluence Area (CA) and on that basis present conclusions which will inform a land-use decision for the area. It has been undertaken in partial fulfilment of the academic requirements of the M. Phil (Environmental Science) course offered by the Department of Environmental and Geographical Science of the University of Cape Town (UCT). It also serves as a working document informing the Cape Town City Council's (CCC) land-use planning for the CA, and for that reason aims for a balance between academic rigour and the concise, pragmatic style of a report. It should also be noted that this study is almost wholly contingent on a baseline document prepared between January and March 1994 by the 1993/94 M. Phil class. That document identified the totality of environmental factors which might influence land-use planning in the CA and is the point of departure of this dissertation.

Full textThe health impacts of urban air pollution are a growing concern in our rapidly urbanizing world. Urban air pollutants show high intra-urban spatial variability linked to urban land use and land cover (LULC). This correlation of air pollutants with LULC is widely recognized; LULC data is an integral input into a wide range of models, especially land use regression models developed by epidemiologists to study the impact of air pollution on human health. Given the demonstrated links between LULC and urban air pollution, and between urban air pollution and health, an interesting question arises: what is the potential of LULC modifications to mitigate the health impacts of urban air pollution?
In this dissertation we assess the potential of LULC modifications to mitigate the health impacts of NO2, a respiratory irritant and strong marker for combustion-related air pollution, in the Portland-Vancouver metropolitan area in northwestern USA. We begin by measuring summer and winter NO2 in the area using a spatially dense network of passive NO 2 samplers. We next develop an annual average model for NO2 based on the observational data, using random forest—for the first time in the realm of urban air pollution—to disentangle the effects of highly correlated LULC variables on ambient NO2 concentrations. We apply this random forest (LURF) model to a 200m spatial grid covering the study area, and use this 200m LURF model to quantify the effect of different urban land use categories on ambient concentrations of NO2. Using the changes in ambient NO2 concentrations resulting from land use modifications as input to BenMAP (a health benefits assessment tool form the US EPA), we assess the NO2-related health impact associated with each land use category and its modifications. We demonstrate how the LURF model can be used to assess the respiratory health benefits of competing land use modifications, including city-wide and local-scale mitigation strategies based on modifying tree canopy and vehicle miles traveled (VMT).
Planting trees is a common land cover modification strategy undertaken by cities to reduce air pollution. Statistical models such as LUR and LURF demonstrate a correlation between tree cover and reduced air pollution, but they cannot demonstrate causation. Hence, we run the atmospheric chemistry and transport model CMAQ to examine to what extent the dry deposition mechanism can explain the reduction of NO2 which statistical models associate with tree canopy.
Results from our research indicate that even though the Portland-Vancouver area is in compliance with the US EPA NO2 standards, ambient concentrations of NO2 still create an annual health burden of at least $40 million USD. Our model suggests that NO2 associated with high intensity development and VMT may be creating an annual health burden of $7 million and $3.3 million USD respectively. Existing tree canopy, on the other hand, is associated with an annual health benefit of $1.4 million USD. LULC modifications can mitigate some fraction of this health burden. A 2% increase in tree canopy across the study area may reduce incidence rates of asthma exacerbation by as much as 7%. We also find that increasing tree canopy is a more effective strategy than reducing VMT in terms of mitigating the health burden of NO 2.
CMAQ indicates that the amount of NO2 removed by dry deposition is an order of magnitude smaller than that predicted by our statistical model. About one-third of the difference can be explained by the lower NO2 values predicted by CMAQ, and one-third may be attributable to parameterization of stomatal uptake.

Full textENGLISH ABSTRACT: In this study, a cost benefit analysis was done to determine the best possible methods for postmining reclamation. A comparison was made between a conventional method with additional organic material added to the soil and a Backgrounding method where cattle are reared on the land. The best method, according to the financial model that was built, was the method of Backgrounding cattle on the rehabilitated land. The main reason for this outcome may be due to the fact that the meat that is produced is a high value product. It might not be practically applicable to mines at this stage, but the calculation provides an insight into the possibilities that reclaimed mine land holds for the agricultural industry.

Full textENGLISH ABSTRACT: The River Health Programme (RHP) is an assessment tool for monitoring the ecological state of rivers to ensure that they remain fit for use by present and future generations. This study, forming part of a RHP assessment conducted on the south-western Cape Hout Bay, Lourens and Palmiet Rivers, has the aim to (1) zone the rivers for representative site selection, (2) assess their habitat integrity (HI), (3) determine the influence of land use on riverine HI and (4) assess the river water quality at the time of the RHP assessments. (1) The desktop geomorphological zonation method used in RHP assessments has not been sufficiently previously tested on short rivers draining the Western Cape Mountains. The Lowland River Zone of the rivers studied, as well as the Hout Bay River’s Upper Foothill Zone, were found to have steeper gradients than expected, probably due to these rivers being shorter and consequently steeper than any on which the method was previously tested. The notion of one gradient river classification system being applicable throughout South Africa, with its diverse geology and climate, is unlikely. Rather a classification system modified for various physiographic features regions or by a factor based on river length is more realistic. (2) Although there is a general longitudinal decrease in HI downstream along the Hout Bay and Lourens Rivers, coinciding with increased anthropogenic activities, HI improves in the Palmiet River’s lower reaches through the Kogelberg Nature Reserve. Surrounding land use thus seems to be a major determinant of HI. Although the Index of Habitat Integrity (IHI) used appears to achieve its aim, it was found to be subjective. Categorisation of the IHI scoring is suggested. (3) The amount of natural versus disturbed land use occurring upstream of a site at a regional and local scale, is a good predictor of riverine HI. Regional alien forestry and local urbanisation have significantly strong negative effects on instream (r2 = -0.80, r2 = 0.80, p<0.05) and riparian (r2 = -0.81, r2 = -0.83, p<0.05) HI. Different land use types therefore appear to affect riverine HI at differing scales and thus managers must not only think on a local but also a catchment scale. (4) In the Hout Bay River, a filtering system (e.g. wetland) appears to improve the water quality between the middle and lower reaches. Along the Lourens River, high total dissolved salts, conductivity and inorganic nitrogen concentrations in the middle reaches are cause for concern. Along the Palmiet River there appeared to be insufficient oxygen to support most aquatic life forms at Grabouw. Impoundments in the middle reaches act as sinks for nutrients and salts, but the Huis and Krom tributaries downstream then appear to degrade the water quality of the Palmiet River’s lower reaches within the Kogelberg Nature Reserve. Together with the results of simultaneous biotic assessments, these results should be used to develop management actions to improve the ecological health of these rivers. The results have been used in a State-of-Rivers Report for the south-western Cape.
AFRIKAANSE OPSOMMING: Die Riviergesondheidsprogram (RGP) is 'n asseseringsinstrument wat die ekologiese stand van riviere monitor om te verseker dat hulle steeds bruikbaar bly vir huidige en toekomstige geslagte. Hierdie studie maak deel uit van 'n RGP-assessering van die Lourens-, Houtbaai- en Palmietrivier in die Suidwes-Kaap en het ten doel om (1) die riviere te soneer vir verteenwoordigende terreinseleksie, (2) die habitat-integriteit (HI) te assesseer, (3) die invloed van grondgebruik op rivier-HI te bepaal en (4) die kwaliteit van rivierwater tydens die RGP-assesserings te bepaal. (1) Die geomorfologiese-soneringsmetode wat in RGP-assesserings gebruik word, is nog nie voorheen genoegsaam vir die kort riviere wat die Wes-Kaapse berge dreineer, getoets nie. Daar is bevind dat die studiegebied riviere in die laagland-sones skerper gradiënte het as verwag, gehad het. Dit kan moontlik toegeskryf word aan die riviere wat korter en dus steiler is as enige van dié wat voorheen met die metode getoets is. Die moontlikheid dat een gradiëntklassifikasiestelsel vir riviere regdeur Suid-Afrika met sy diverse geologie en klimaat toegepas kan word, is onwaarskynlik. 'n Klassifikasiestelsel aangepas vir verskillende fisiografiese streke of met 'n faktor gebaseer op rivierlengte, is meer realisties. (2) Alhoewel HI stroomaf langs die Lourens- en Houtbaairivier in die algemeen longitudinaal saam met die toename in antropogeniese aktiwiteite afneem, verbeter die Palmietrivier se HI waar dit laer af deur die Kogelbergnatuurreservaat vloei. Die gebruike van aanliggende grond blyk dus 'n belangrike bepaler van HI te wees. Die Indeks van Habitatintegriteit (IHI) bereik klaarblyklik die vereiste doel, maar is te subjektief. Kategorisering van die IHI-waardes word voorgestel. (3) 'n Goeie voorspeller van rivier-HI is die hoeveelheid natuurlike teenoor versteurde grondgebruik stroomop van 'n terrein op 'n streeks- en lokale skaal. Die sterk negatiewe effek van uitheemse plantegroei in die omgewing en lokale verstedeliking op stroom- (r² = -0.80, r² = 0.80, p<0.05 ) en oewer-HI (r² = -0.81, r² = -0.83, p<0.05) is beduidend. Verskille in tipe grondgebruik beïnvloed rivier-HI op verskillende vlakke; bestuurders moet dus plaaslik en aan die opvanggebied dink. (4) In die Houtbaairivier lyk dit asof 'n filtreringstelsel (bv. vleigrond) die waterkwaliteit tussen die middel- en lae gedeeltes verbeter. In die loop van die Lourensrivier is hoë totale opgeloste soute, geleidingsvermoë en anorganiese stikstofkonsentrasies in die middelgedeelte 'n rede tot kommer. In die Palmietrivier by Grabouw was die suurstof te min om die meeste akwatiese lewensvorme te onderhou. Opgedamde water in die middel gedeeltes dien as 'n sink vir voedingstowwe en soute, maar dit lyk asof die Huis- en Kromrivier die waterkwaliteit van die Palmietrivier stroomaf in die Kogelbergnatuurreservaat degradeer. Saam met die resultate van gelyktydige biotiese assesserings, kan hierdie resultate gebruik word vir die ontwikkeling van bestuursaksies om die ekologiese toestand van hierdie riviere te verbeter. Die resultate is gebruik in 'n toestand-van-riviere-verslag vir die Suidwes-Kaap.

Full textENGLISH ABSTRACT: The multifaceted land degradation problem and its associated manifold impacts have attracted research from different disciplines, resulting in varying definitions of the concept. However, most researchers agree that human intervention that deteriorates the state of the environment is the central element. Among the anthropogenic activities that exacerbate land degradation, land cover has been singled out as the salient element. Rapid and unplanned land cover changes are primary manifestations of this problem. UMhlathuze Municipality, the study area which has superior biodiversity richness, is one of fastest growing municipalities in South Africa and is the locale of significant land modifications in recent decades because of a variety of industrial and residential developments. Using Landsat TM imagery acquired for 1984, 1996 and 2004, this study mapped and quantified land cover change and manifestations of land degradation in the uMhlathuze Municipality in conjunction with settlement intensification computed from orthophotographs acquired for 1984 and 2004. Census population statistics were analysed as a reflection of population dynamics and further to gauge related causes of land cover change. Geographical information technology (GIT) was applied as an analytical tool. The results revealed the anthropogenic influences that led to changes in land cover over the 20- year period between 1984 and 2004. The dominant natural cover classes in 1984 declined continuously and human-dominated land categories had increased sharply by 2004. Much of grasslands, forest and wetlands were converted to monotypical agroforestry (sugar cane and forestry plantations), built-up settlement and mining. These changes engendered complete loss of biodiversity (floral and migration of fauna). Bare ground, signifying land degradation, was noticeable although it exhibited a fluctuating trend which could be attributable to differences between the various imagery used. Along with population growth, the area of settlements increased over the study period and spatially sprawled from urban areas. Settlements showed a fairly stable spatial configuration over the 20-year period, but became magnified in medium- and high-density areas. Grassland and wetlands occurring around Richards Bay, as well as indigenous forest near Port Durnford, were identified as critically threatened ecosystems. The proposed industrial development zone and port expansion were recognized as having adverse ecological implications for wetlands. The study concluded that significant land cover changes occurred in the form of natural land cover giving way to monotypical agroforestry, built-up settlements and mining - all to the detriment of pristine natural habitat.
AFRIKAANSE OPSOMMING: Die veelvlakkige probleem van omgewingsdegradasie en die gepaardgaande veelsoortige impakte lok navorsing uit verskillende dissiplines, wat lei tot verskillende definisies van die konsep. Tog is die meeste navorsers dit eens dat menslike invloede die sentrale element is wat die toestand van die omgewing verswak. Van die vele menslike aktiwiteite is grondgebruikverandering uitgesonder as die belangrikste beïnvloeder van agteruitgang van die omgewing. Veral vinnige en onbeplande grondgebruikveranderinge verteenwoordig die primêre manifestasies van hierdie probleem. UMhlathuze Munisipaliteit, die studiegebied met 'n hoë biodiversiteitsrykdom, is een van die vinnigste groeiende munisipaliteite in Suid-Afrika, waar 'n verskeidenheid nywerheids- en residensiële ontwikkelings beduidende grondgebruikverandering oor die afgelope dekades dryf. Met behulp van Landsat TM beelde van 1984, 1996 en 2004, is hierdie studiegebied gekarteer en oppervlaktes gekwantifiseer om grondgebruikverandering en verwante manifestasies van die agteruitgang van landbedekking in die uMhlathuze Munisipaliteit te konstateer. Tesame hiermee is die verdigting van nedersettings ook met behulp van ortofoto’s van 1984 en 2004 aangeteken. Bevolkingsensusstatistieke is ontleed as weerspieëling van die gepaardgaande bevolkingsdinamika en om moontlike oorsake van verandering in grondbedekking te bepaal. Vir hierdie doel is geografiese inligtingstegnologie (GIT ) as analitiese instrument toegepas. Die resultate toon antropogeniese invloede lei tot veranderinge in grondbedekking oor die tydperk van 20 jaar tussen 1984 en 2004. Die dominante natuurlike dekkingsklasse in 1984 het voortdurend verminder en menslik-gedomineerde kategorieë het teen 2004 skerp gestyg. Baie van die grasvelde, woude en vleilande is daadwerklik omskep tot monotipiese agro-bosbou (suikerrieten bosbouplantasies), beboude nedersetting en mynbou. Hierdie veranderinge behels 'n volledige verlies van biodiversiteit (plantegroei en migrasie van fauna). Kaalgrond, wat dui op die agteruitgang van grondbedekking, was ook opvallend, hoewel dit 'n wisselende tendens toon wat ook kan wees as gevolg van die verskille tussen die beeldmateriaal wat gebruik is. Saam met die groei van die bevolking is bevind dat nedersettings oor die studieperiode toegeneem het en in tipiese spreipatrone weg van die stedelike gebiede uitbrei. Nedersettings het 'n redelik stabiele ruimtelike liggingsopset oor die tydperk van 20 jaar getoon, maar het in medium- en hoë- digtheid gebiedeverdeel. Die voorkoms van grasveld en vleiland rondom Richardsbaai, asook inheemse woud naby Port Durnford, is geïdentifiseer as krities-bedreigde ekosisteme. Die voorgestelde nywerheidsontwikkelingsone en hawe-uitbreiding is geïdentifiseer as ontwikkelings met nadelige ekologiese implikasies vir vleilande. Daar is dus tot die gevolgtrekking gekom dat beduidende voortgaande grondbedekkingveranderinge in die gebied voorkom, waarin natuurlike landdekking transformeer tot monotipiese agrobosbou, beboude nedersettings en mynbou - alles tot nadeel van die ongerepte natuurlike habitat.

Full textThe purpose of this research was to quantify the impact of the land reform programme on land use and land cover changes (LULCC) in Chipinge district situated in Manicaland Province of Zimbabwe. The Fast Track Land Reform Programme (FTLRP) of 2000 was selected as the major cause of LULCC in the district. This research addresses the problem of knowing and understanding if there was LULCC in the district before and after the enactment of the FTLRP in the year 2000. The research objectives of this study were as follows: to investigate the impact of the FTLRP of 2000 on land use and land cover in Chipinge district; to test the use of Landsat earth observation data in quantifying the changes on land use and cover from 1992 to 2014 in Chipinge district and to predict LULCCs in the year 2028 in Chipinge district. The methodology for detecting the impact of LULCC was based on the comparison of Landsat MSS, TM, ETM+ and OLI/ TIRS scene p168r74 images covering Chipinge district taken on diverse dates in five different years. In order to prepare the Landsat images for change detection analysis, a number of image processing operations were applied which include radiometric calibration and atmospheric correction. The images were classified using the Support Vector Machine (SVM) and evaluation was done through accuracy assessment using the confusion matrix. The prediction of LULCC in the year 2028 was modeled by the Markov Chain Analysis (MCA) and the Cellular Automata Markov Chain Analysis (CA MCA) so as to show land distribution in the future. The results show that agricultural farmland, estates and area covered by water bodies declined whilst there was an increase in built-up areas, forest land and bare land since the enactment of the FTLRP. The prediction results show that in the year 2028, there will be a decrease in the amount of land covered by water bodies, forest and agricultural farmland. There will be an increase in the amount of built-up in the year 2028 as a result of population growth. It is the recommended in this study that better remedies be put in place to increase forest cover and also the use of high resolution images in further studies. There should be exploration of the relationships between LULCC, socio-economic and demographic variables would develop more understanding of LULCC. The study also recommends the preparation of a proper land use plan to deal with a reduction in the growth of settlement which is vital in the planning and management of social and economic development programs.
