    Analysis of the applicability of eco city concepts to Sri Lankan cities
    Ranaweera, HJC; Munasinghe, J
    The concept of ""Eco-Cities" has recently attracted attention in planning and development tield. Ljntil now, it is hardly can find a standardized definition of the term ··Eco-City". Nevertheless, in genera L the concept of Eco-Cities is closely aligned with the concept of sustainable development, through the adoption of sustainability as the driving objective and the integration of ecological and resources management principles into the urban planning process. Since prehistoric times the ceo systems have been modified by man. But in recent times, man suse of land has increased in intensity. With the globe becoming more populated. less desirable lands are being settled and the modification of natural systems has become more extreme. While no reasonable individual intends to destroy his own environment or livelihood .collectively man has greatly disrupted the natural ecological systems of which he is a part. Natural disasters all over the world today arc dramatically illustrating this and reveal that our contemporary land use and development patterns are not sustainable. The ecological principles in urban planning on gmate from the fundamental objective of sustainability and the Eco-Cities are a concept to achieve this sustainability by taking the ecological principles as the central driving force for the planning of cities. This was in the discussion and practices of many developed nations and in particular the fast developing nations of China. Korea and Japan, recognizing this as a way to address the sustainability ISSUes .Sri Lanka today presents a picture of a country experiencing rapid urban growth and social change. The cities all over the country is experiencing high rate of migration, compaction and sprawling effects. The agricultural lands are moving fast in to residential land lots, vulnerable and sensitive areas are becoming severe environmental threats. urban transformation can be seen every aspects. Yet the Sri Lankan Cities are reliving on conventional land use development strategies and struggling with usual development problems of economic, social and environmental. Among those the environmental matters are less prioritized and the Sri Lankan cities are with severe environmental degradation. Moving for innovative sustainable city development strategies such as Eco City development are still under recognition either due lack of the awareness or these concepts are not much explored or localized in the planning industry in Sri Lanka. The attempt of this study is to examine the Eco city concepts practiced around the world and find the concepts that are capable to resonate with local urban challenges and useful for planners and locally applicable in physical development in Sri Lanka and to demonstrate those with an example in Sri Lanka while taking in to consideration the local conditions. negative and positive features. Subsequently the study is intended to explore the importance and possibilities of adopting eco city concepts in city development in Sri Lanka while making knowledge and awareness about the concepts

    An evaluation of the concept of decentralization in its applicability to the development of Colombo metropolitan region
    (2014-07-03) Rajakaruna, SA
    This study is concerned with planning the development of the Colombo Metropolitan Region by taking into consideration the applicability of the concept of decentralization. The study has been carried out within the Colombo Metropolitan Region defined by the UNDP assisted Master Planning Team. The discussion of this study has been divided into three parts comprising eight chapters. Part I is the introductory; it discusses the background to the Colombo Metropolitan Region and includes three chapters. The first chapter introduces the existing setting of the study region. Having an idea regarding the study region, the second chapter discusses the spatial relationships of the study region in the national context. The final chapter of this Part introduces past attempts in the planning of the region, particularly in the Abecrombie Colombo Regional Plan. Part II contains the analytical portion of this study and it comprises four chapters. The Part II examines the planning options available for the development of Colombo Metropolitan Region based on the analysis of the study. It begins in the fourth chapter, by discussing the analytical frame of the study region. The conceptual options available for the development of the Colombo Metropolitan Region is discussed in the fifth chapter. The next chapter has critically evaluated the concept of decentralization. Having had an idea of the concept of decentralization, the final chapter of this Part deals with the applicability of this concept for the planning development of the study region. Part III of the study and the chapter in it gives the main conclusions and recommendations of this study.

    Monitoring spatial and temporal urbanization pattern in the Jaffna peninsula using remote sensing techniques
    Raveendran, S; Mahanama, PKS
    This research examines the spatiotemporal pattern of urbanization in the Jaffna Peninsula using Remote Sensing and spatial analysis techniques. The spatial and temporal information on urbanization pattern in the Patna Peninsula is very essential for various planning and development related activities. There was no research undertaken on the pattern of urbanization in the Peninsula for the last few decades. This research has studied the urbanization pattern based on spatial data for the last 50 years compiled from satellite images and Aria! photograph. Medium resolution images of the study area were analyzed to map out the pattern through the techniques of Geographical Information System and Remote Sensing. Supervised classification techniques were used to analyze the images to recognize the spatial pattern of urbanization. The recognized pattern of land use changes were analyzed using the techniques of spatial metrics. A dynamic spatial pattern of urbanization has been observed in the peripheral areas towns, Jaffna, Chavakachcheri, Nelliyadi, Point Pedro and Chunakam towns and ribbon development along the main transport routes in the Peninsula. Substantial changes in the urbanized area have been prevalent around the Jaffna town which is largest town in the Peninsula. Urbanization took place at a slow growth rate in the 1960s and 1970s but has grown rapidly since the 1980s. Again in 1990s, the growth rate had declined due to the intensive war centered in the Jaffna Peninsula. There has been significant urban growth in the Peninsula during the last decade as a result of the political changes in the country. The urbanization process has developed fragmel'lted and heterogeneous land use combinations in the fringe areas of towns in the Peninsula. However, the regeneration process in the city core during the last few years has shown a decreasing trend in the peripheries. The study also shows that the urbanization trend in the Jaffna Peninsula has been causing numerous consequences economically and environmentally. Further research works deploying high resolution satellite images to survey the urbanization pattern are required in the future.
