Abstract

The paper deals with an actual condition of mangrove ecosystem in Segara Anakan Central Java by analysing them from remote sensing satellite image such as SPOT XS and Landsat 1M recorded in between 1981 and 2003. Digital and manual image analysis were applied Field checks were conducted in 199 3 and in 2005.The result show that three aspects of mangrove ecosystem can be studied from the remote sensing data, i.e. mangrove zonation, land cover changes and mangrove physical ecosystem changes. In mangrove zonation, it showed that three to four zones in mangrove forest zonation can be identified by satellite digital data analysis, especially in accretion areas. Mangrove of these areas actually suffers from human pressures, mainly for fishery and agriculture activities, and environmental changes. Lagoon morphometric decreased considerably and its influenced the existence of the mangroves. Mangrove extend in Segara Anakan, the mangrove forest covers 8600ha in 1987 and 7500ha in 1998, and in 2008 it decreased considerably. The lagoon of Segara Anakan undergoes to be disappeared by sedimentation processes from its hinterland In consequence mangrove ecosystem in the region is in dangerous condition

Abstract

The 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.

Abstract

This paper assesses the present micro-environmental conditions of a dissected highland", College Tilla of Agartala city of North-East India. Geomorphologically Agartala city is located in a part of the basin of R Haora which consists of two main geomorphic units namely dissected high lands or tilla lands and adjacent flat alluvium lands. The elevated geomorphology of the tillalands play important role for the development and preservation of typical high landenvironment and rich ecological resources in some pockets of flat alluvium of R Haora basin for long time. Since the urban activities started on College Tilla only during early 2dh century the variation of flora and fauna of the tilla land is still.remarkable. During the recent period rapid extension of Agartala city causes theproblem of geomorphic degradation and affects the natural environmentalcondition of the area. Due to the construction of the buildings, roads, boundaries, water pipe lines etc the dense vegetation cover is removed rapidly and as a result of that now soil erosion and medium size land slides are becoming very commonfeatures in the city. Besides that the ecology of this area is now under serious degradation due to desperate human interventions on the tilla lands of Agartala City

Abstract

The southern slope of Merapi Volcano plays a significant role to Yogyakarta Municipality groundwater resources. Groundwater recharge, herein meant as the effective precipitation that infiltrates into unsaturated zone andpercolates to water table after exceeds the soi/field capacity, is the main subject in this article. The objective of this research is to apply WTF method to spatially define the groundwater annual recharge. Four wells are selected to represent some geomorphologic units. Then, four A WLR installed to record the yearly shallow groundwater table fluctuation. In addition, WTF method requires groundwaterfluctuation and specific yield data. The rate of groundwater recharge in every well confirms the varying value. However, it seems that geomorphologic unit may be principally control to the time series variation of shallow groundwater jluctuationthat results in groundwater recharge characteristic. The volcanic slope unit (above 600 m as!) has the lowest water table fluctuation indicates the resistant comportment to the annual rainfall. Ihis unit is characterized by the relatively high magnitude of recharge of approximately 4270 mm/year.

Abstract

Problem 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.

Abstract

Prioritizing public tramjport in large cities requires huge amount of money.In Kuala Lumpur for example, public transport services are relatively poor and inefficient due in part to the inability by the major operators to mobilize ample investment capital. Besides, the new funding systems such as the Public Transportation Trust Fund (PTTF) may not be able to solve the problem because they are still unclear and incoherent. Other key challenges are: lack of a pro-transit policy. rapid motorization. urban decentralization as well as dependence on farerevenue and banks to fund new investments. CrucianF. due to the poor design of private rail concessions, government intervention has been inevitable.

Abstract

At least.. there are /11.'0 points of concern in the urbanization studies, i.e. to see urbanization as a process of structural change of rural population (and areas) and to give attention to the interrelationships (in terms of economic, demographic,political. cultural, technological, social changes) between two different types ofgeographical areas, i.e. urban and rural. These two points of concern lay afoundation for a further development of recent~v urbanization studies, called rural urbanization. So far. it is indicated there are three main streams of perspectives in urbanization studies, i.e. modernization, dependence, and inter-dependence urbanization. Each of these perspectives gives a special color on rural urbanization process. At least there are three fimdamental questions that can be raised from theoretical discussion of urbanization, i.e. (1) are distinct regions that recentlyemerge different from what conventionally known as rural and urban areas; and ifthese are special regions. (2) what are the underlying factors and forces that encourage the emergence of these distinct regions? (3). what kind of policies needed to effectively to cope the development of these distinct regions? These three questions actually are underlying three main areas of rural urbanization researchin a certain region, i.e.: (1) answering WHAT. WHERE, and HOW of the process of rural urbanization; (2) finding the main factors affecting the process; and (3) what kind of actions can be carried out dealing with rural urbanization 'problems

Abstract

This paper examines globalization and localization processes that have occurred in tlze most developed and the least developed countries of the world respectiveZv. SpecificalZv, it jocuses on Sub-Saharan Africa (SSA) as a case study.While globalization is considered as a pride to the West and Europe, Africa is still being regarded as localized. The paper goes filrther to address the imbalance and disparity that have existed bern.'een the developed and underdeveloped countries in the areas of electronic, commerce, Information Communication Technology (ICT) among others. Also, the opportunities and challenges posed by globalization are critically focused. The paper identifies the Aji-ican problems of underdevelopment and proposes strategies by which these problems could be solved so that Africa would be able to 'catch up' in the globalization process.

Abstract

This study assessed the effectiveness of the existing land conservation techniques in the peril-urban area of Kadoka metropolis with the aim of ascertaining if the existing conservation methods have helped to alleviate land degradation, andprovide sustainable land use. Random sampling method was used to collect datafrom field observation, measurement and semi-structured interview which are analyzed using descriptive statistics. The results revealed that there exist local conservation techniques along with the modern techniques, some are physical and others are biological methods, even though techniques such as agI'o forestry, which is known to be the best method of farming is present but is yet to take root in the area. Some of these conservation methods are not standardized neither are they implemented in a scientific manner to. ensure e.Df!Ctiveness and efficiency without causing further damage to the lalld, as a result, there may be no end to land degradation in Kaduna if the current approaches to conservation are not improved on. it is suggested that improved water management, improved farming techniques, economic empml'ennent and education of the land users be employed in refilling existing techniques, through which poor management practices such as bush burning, monocropping and overgrazing lvill be avoided 'while fanners will easily embraced new practices such as agro forestry, which provides fanners with income and food all year round as well as protect the environmentfrom degradation.
