growth pattern and the industrial development of the lagos region, nigeria
No full textThis paper examines the nature, growth and spatial pattern of industries within the Lagos Region. Industrial activities in this region grew progressively over the year from mere brickwork, palm oil mills, printing press, soap factory, and metal container factory to capital intensive manufacturing. Indeed, the number of industrial establishments increased from 122 in 1962 to 637 in 1993. Lagos developed into Nigeria's leading industrial center; especially following the expansion in its service and administrative sectors. Whereas, chemicals and pharmaceutical; and basic metal, iron and steel and fabricated metal products industry groups dominate in industrial scene, wood and wood products (including furniture); and non-metallic mineral products are rare. The spatial pattern shows that industrial establishments vary amongst the industrial estates/areas, and also among the industry groups. Ikeja/Ogballsheri industrial estate/area dominates the industrial scene
Land Conservation Initiatives Around MT. Elgon National Park, Eastern Uganda
No full textThe goal of this paper is to provide an investigation of the land conservation strategies adopted by farmers to control land degradation around Mt. Elgon National Park, Uganda. Primary data were obtained through household survey conducted in Mutushet and Kortek parishes, Kapc.horwa district between June to December, 2003. The differences between adopters and non-adopters of land conservation practices in terms of contact with extension workers, tribe, size of productive family labour, membership to farmer organization, education level, and participation in communal land management activities and frequency ofnatural hazards on private agricultural landfj were examined Farmers have increasingly adopted different structural measures like terraced farming, construction of waterways, check dams, retention walls, and gull control. Similarly, they have also adopted different biological measures including alley cropping, bamboo plantation in gullies, mulching and applied organic and inorganicfertilizers to control land degradation. However, farmers have not been able to control land degradation to a great extent due to relatively weak technological backup by concerned agencies. It was concluded that severity of land degradation is higher in the parishes with traditional farming methods because farmers are not provided with the necessary technical advisory services
Analysis of Intra-Urban Traffic Problems in Nigeria: A Study of Lagos Metropolis
No full textProblem of trqffic congestion is common in most big cities of the world.Drivers of privately owned vehicles and passengers may experience substantially loss of time while in traffic jam. Also, solutions to causes of this menace are well documented in the literature. In spite of the vast studies and applied measures toreduce these jams, the problem seems to be growing stronger on daily basis. One ofthe o~jectives of this study is to examine (l the intensity of traffic congestions are similar along the routes, and on d(fJerent days of the 'week within the ci~y of Lagos.The paper also examines the traffic pattern along ten selected routes within five metropolitan areas in the state. The study shows that 57% of the commuters and motorists in the study area do spend an average of 30 to 60 minutes in congestedtraffic. Three peak periods of traffic congestion were recognized. Indiscriminateparking, road side trading, flooding, existence o.fpot-holes on these roads, vehiclesbreaking down and absence o.f traffic light at some road intersections are some ofthe identified major causes of traffic congestions. Mondays were recognized as the most congested day by 57% of motorists and commuters interviewed. The analysis o.f variance result shows insign(ficant variation in traffic congestion among the fivelocal government areas. However, the observed spatial and temporal pattern o.l vehicular traffic congestion enabled us to suggest possible measures for the reduction of traffic congestion within the metropolis
APPLICATION OF REMOTE SENSING TO ESTIMATE ABOVE GROUND BIOMASS IN TROPICAL FORESTS OF INDONESIA
No full textThis work aims to estimate Above Ground biomass (AGB) of a tropicalrainforest in East Kalimantan, Indonesia using equation derived from the standvolume prediction and to study the spatial distribution of AGB over aforest area.The potential of remote sensing and field measurement data to predict standvolume and AGB were studied Landsat ElM data were atmospherically correctedusing Dark Object Subtraction (DOS) technique, and topographic corrections wereconducted using C-correction method Stand volume was estimated using field dataand remote sensing data using Levenberg-Marquardt neural networks. Standvolume data was converted into the above ground biomass using available volume- AGB equations. Spatial distribution of the AGB and the error estimate were theninterpolated using kriging. Validated with observation data, the stand volumeestimate showed integration of field measurement and remote sensing data hasbetter prediction than the solitary uses of those data. The AGB estimate showedgood correlations with stand volume, number of stems, and basal area
HUMAN GEOGRAPIES OF DECENTRALIZED INDONESIA
No full textOne of the aims of this short paper is to sketch human geographicaldimensions of decentralized Indonesia. The paper is structured around a series ofsub-disciplinary issues that arise from processes evident over the past decade. Ineach case, I seek to develop a theme around existing work by geographerspublished in English language internationally-refereed journals. In this way, asecond aim of the paper is to provide (especially for Indonesian geographers whooften do not or cannot access these 'international' journals) a sense of the range ofwork that is considered to constitute 'human geography' in English-speakingacademic worlds. In other words, I suggest pathways for human geographicalresearch in an era of decentralization in Indonesia building upon existingscholarship published in the English language
A GIS MODELLING APPROACH FOR FLOOD HAZARD ASSESSMENT IN PART OF SURAKARTA CITY, INDONESIA
Get PDFThis research is aimed to assess the flood hazard in part of Surakarta usinghydrodynamic modelling. Flo2D software is used to simulate the flood for 10, 25and 100 year return period. The modeling results include two flood parameters, i.ewater depth and flow velocity. A comparison was made in flood hazard mappingbetween single parameter and multi parameters. The multi parameters hazardmaps improve the reliability of the hazard class delineation. The impact assessmentis done in two point of view, human safety and property damage. The furtherimpact assessment is done by calculating the number of buildings affected by flood
EFFECTIVENESS OF TRANSBOUNDARY COLLABORATIVE CONSERVATION IN VIRUNGA NATIONAL PARKS
Get PDFThe general aim was to assess the effectiveness of transboundary collaboration in thecontiguously adjoining protected areas of Virunga massive. The specific objectives were, a)to identify the role of different stakeholders in the management of transboundarycollaboration, b) to assess the level of collaboration between the three authorities andgovernments, c) to assess the participation of local communities in planning andmanagement of the natural resources, and d) to establish the effectiveness of the approach inmanaging natural resources. The study employed both the primary and the secondary datasources. The questionnaires were used to collect data from officers and the discussion withrelevant officials was conducted. A total 90 local community members were interviewed fromthe three countries. The secondary data were collected from management of MgahingaNational Park, Parc Nationaux des Volcano of Rwanda, Parc National des Virunga IGCPstaff and crossection of protected areas stakeholders and government institutions of the threecountries. The Results indicated that regarding the collaborative management between thethree authorities, it was found out that information exchange and joint patrol were the majoractivities. By 2003, in Uganda poaching had reduced to 1 case and the wire snare to 54which accounted for 2.3% and 8.8% respectively from the 23.3% and 19.6% in 1997.However the figures in Rwanda reduce slightly due to the security situation. It was alsodiscovered that the local communities of DR. Congo and Rwanda were highly involved inplanning of conservation activities that the case with Uganda
COMMUNITY BASED APPROACH TO ASSESS FLOOD RISK PERCEPTION ALONG CODE RIVER
Get PDFThis p a p e r presents a flood risk perception and coping mechanism along CodeRiver, Yogyakarta Municipality based on the community approach. A total of 90households were interviewed. Data were analysed using Statistical Package for theSocial Sciences (SPSS) Program. The result indicated that there are no differencesof flood risk perception among the zones (p >.05). Perception of flood risk is influencedby several variables: gender, length of stay, RW’s risk level, distance betweenrespondents’ house and river and impact level of flood. Whereas, all types of community’scoping mechanism (technological, social, and economical) are influenced by impact levelof flood

Get PDFThe study was to assess the effects of land use change on runoff in the Bedog sub watershed.Soil and Water Assessment Tool-Water Balance (SWAT-WB) hydrological modeling was usedto predict runoff for years of 2001, 2006, and 2010. Land use in Bedog has rapidly changedin last few decades due to agglomeration process in Yogyakarta City. Coverage of mixedgarden decreased during period of 2001-2010 despite still as predominant land use in total.On the other side, change detection analysis revealed that there was an increase ofsettlements coverage from 9.51% to 13.79% in the same period. Sensitivity analysis revealedthat soil properties were the most sensitive parameters on runoff generation. Calibration wasperformed for years of 2001, 2006, and 2010 and the result shows an acceptableperformance in runoff simulation. Changes in land use were responsible for an increase inthe annual runoff between 3.42% – 4.67%. This study showed that dynamics of runoff can bepredicted by forecasting and simulating future land use
