Semarang is the capital city of Central Java Province, as a metropolitan city, Semarang has the capablity to support the rapid development of the city , one of the evident is the highly of activity on physical infrastucture, one of them is the construction of residential areas along the high rate of population growth. Settlement area development activities emerge the negatively impact to reduce the existence of open space area. This study uses a quantitative method through positivistic approach. Research data presented by the form of figures and the analysis using the statistics. This study was first carried out in 2006 and 2011 to analyze the spatial through digitized the image map of Semarang, and the results of the digitization of spatial land area of open space and a residential area, which is used to formulate some stage subsequent analysis: 1) Identification and analysis of the influence of the development of residential areas against the open space in the city, 2) Analysis of the acceleration of the projected change of land per year in Semarang in 2006-2020, 3) Analysis of the application of open space 30% (sample in District Tembalang). The result of this analysis showed the relationship between the relevant mutual influence. The rate of population growth and development of residential areas with a relationship of mutual influence supply and demand. Then, as the development of residential areas causes the reduction of open space. In additon, the background of this problem is how to formulate the recommendations to control the land use plan , in order to create an ideal city land use in the future.

The transit system serving Greater Vancouver has high ridership and a high rate of growth. Using as a base the well-designed, well-patronized trolleybus grid in the City of Vancouver, an inter-connected suburban bus network has been created, with radial, cross-radial, and local routes meeting on a timed connection basis at suburban shopping centres and other foci. Planners' thoughts for the future include greater emphasis on the micro and macro aspects of land use and relations to transit; the use of capital intensive modes for heavy trunk routes; and the use of various forms of para-transit for low-density and certain feeder applications.

Abstrak. Pesatnya pertumbuhan penduduk dan tingginya perkembangan pembangunan, menyebabkan banyaknya kawasan yang beralih fungsi menjadi kawasan yang bukan peruntukan yang sesuai yang telah ditetapkan oleh pemerintah termasuk ruang terbuka hijau (RTH) yang berfungsi untuk menunjang kualitas hidup masyarakat di dalam suatu kota baik dari segi lingkungan maupun kesehatan. Pesatnya perkembangan suatu kota tentu banyak menarik minat masyarakat untuk pindah menuju kota tersebut, semakin meningkatnya jumlah penduduk tentu juga meningkatkan kebutuhan akan oksigen. Untuk itu Kota Bireuen dituntut mampu menyediakan RTH untuk mengimbangi kebutuhan oksigen masyarakat kota itu sendiri. Penelitian ini bertujuan untuk menghitung ketersediaan RTH yang direncanakan di dalam RDTR Kota Bireuen. Metode yang digunakan dalam penelitian ini ada lah metode deskriptif dengan teknik survai. Sedangkan analisis kecukupan RTH menggunakan rumus berdasarkan luas daerah dibagi dengan RTH yang tersedia. Hasil perhitungan analisis RTH di dapat bahwasannya RTH Kota Bireuen sebesar 46,96%.Kata Kunci: Bireuen, RTH, RDTR Abstrack. The rapid growth of population and the high development of the developmental, causing the number of areas that switch functions to areas that are not appropriate designation established by the government including green open space (GOS) that serves to support the quality of life of people in a city both in terms of environment and health . The rapid development of a city would attract many people to move to the city, the increasing number of people of course also increases the need for oxygen.

Urban sprawl is a global phenomenon in the contemporary era. It is mostly taking place in the less developed countries due to natural increase and consistent movement of people into the mega cities and large urban centers. The phenomenon has globally gained attention from diverse researchers in the field of urban geography, environmental studies, city and region planning in view of its significant influence on the urban environment. However, the effect of sprawl on urban livability and economy in Nigerian cities is scarcely investigated especially in Northern Nigeria. This research explores the social and economic effects of urban sprawl in Kaduna metropolis. Remote Sensing and Geographic Information System (GIS) Technologies were applied for the analysis. The study found that Kaduna metropolis has experienced a progressive increase in the built-up area; in 2006 it had an aerial coverage of 13,980 hectares, a rise of 107.91% from 2001 aerial coverage of 6724 hectares. In 2012, the city had an aerial coverage of 15,808 hectares, an increase of 13.08% from 2006. Conversely, there has been a remarkable decrease in percentage of vegetation (1,458 hectares) and agricultural (11,739 hectares) land areas. In turn, such changes has adversely affected urban facilities or utilities such as pipe-borne water, electricity, health facilities, schools, security, transportation, wastewater infrastructures and fire safety services, which has become overstressed. Economic crisis has manifested in the rise of unemployment and escalating number of urban poor. Residential land use has encroached into open spaces while commercial activities overrun residential areas. Increase in distance and journey time make travel cost unbearable to the common man. These and social fragmentation retard livability in the city. Thus calls for a balance sustainable development in Kaduna metropolis and effective management of urban growth by the Kaduna Capital Development Board Authority. In due course, smart growth policy, growth management, urban containment, effective land use planning and public facility adequacy have been recommended to foster viable urban growth in Kaduna city and elsewhere.

ABSTRACTThe development of big cities in Indonesia especially Jakarta City which is developing very rapidly is marked by the rapid development of physical development, thus affecting the increasing population and land use resulting in a decrease in the amount of vegetation cover. The main problem of the existence of Open Green Space (RTH) in Jakarta is the increasingly reduced / limited land and inconsistencies in implementing spatial planning. The reduced green space is caused by changes in land use that is relatively significant so that green space in Jakarta has not met the target of 30% of the total area, especially in the District of Kramatjati. The purpose of this study is to calculate the need for green space within a district. The method used is the initial data processing (radiometric correction, pancarrage, mosaic, cropping) and calculation of vegetation density values based on Normalized Defference Vegetation Index (NDVI). Based on the results of NDVI calculations using Pleiades Image Data in 2015, that in Kramat Jati Subdistrict there were 225.17 ha as vegetation areas, while 918.93 ha were non-vegetation areas. The results of the calculation are then divided into density levels, ie, a rare density of 48,595 ha, medium density of 34,446 ha, and high density of 160,609 ha. The conclusion obtained is that green open space in Kramat Jati Sub-district is planned to cover 12.38% of the entire Kramat Jati area. However, based on NDVI results, green open space in Kramatjati has reached 19.68% of the entire district area. And  terms of quantity, then the amount of green space has been fulfilled. Key Word : open green space (RTH), Normalized Defference Vegetation Index (NDVI), Pleiades Image ABSTRAKPerkembangan kota-kota besar di Indonesia khususnya Kota Jakarta yang berkembang dengan sangat pesat ditandai perkembangan pembangunan fisik yang cepat, Sehingga mempengaruhi semakin meningkatnya jumlah penduduk dan pemanfaatan lahan yang mengakibatkan berkurangnya jumlah tutupan vegetasi. Permasalahan utama keberadaan Ruang Terbuka Hijau (RTH) di Kota Jakarta adalah semakin berkurangnya/keterbatasan lahan dan ketidak konsisten dalam menerapkan tata ruang. Berkurangnya RTH disebabkan oleh perubahan penggunaan lahan yang relatif signifikan sehingga RTH Jakarta belum memenuhi target 30% dari total luas wilayahnya terutama di Kecamatan Kramatjati. Tujuan dari penelitian ini adalah untuk menghitung kebutuhan RTH dalam satu lingkup kecamatan. Metode yang digunakan adalah pengolahan data awal (koreksi radiometrik, pansharpen, mozaik, cropping) dan perhitungan nilai kerapatan vegetasi berdasarkan Normalized Defference Vegetation Indeks (NDVI). Berdasarkan hasil perhitungan NDVI dengan menggunakan data Citra Pleiades Tahun 2015, bahwa di Kecamatan Kramat Jati terdapat 225,17 ha merupakan daerah vegetasi, sedangkan 918,93 ha adalah daerah non vegetasi. Hasil perhitungan tersebut kemudian di bagi dalam tingkat kerapatan yaitu kerapatan jarang sebesar 48.595 ha, kerapatan menengah sebesar 34.446 ha, dan kerapatan tinggi sebesar 160.609 ha. Kesimpulan yang diperoleh adalah RTH di Kecamatan Kramat Jati direncanakan seluas 12,38 % dari seluruh wilayah Kramat Jati. Namun, berdasarkan hasil NDVI, RTH di Kramatjati sudah mencapai 19,68% dari seluruh luas kecamatan dan dari segi kuantitas, maka jumlah RTH telah terpenuhi.    Kata Kunci: Ruang Terbuka Hijau (RTH), Normalized Defference Vegetation Indeks (NDVI), Citra Pleiades

Given that urbanization is considered as one of the most signicant anthropogenic alteration of the overall environment, the present study attempts to understand spatial-temporal characteristics of urban population growth and its implications on land-use as well as understanding their relationship with environmental degradation with special focus on the Kolkata, the capital city of West Bengal. Urbanization is one of the major driving forces behind the development of today's land-use and land cover system. A large number of contemporary urbanization has been characterized as urban sprawl namely in an extensive form of land-use for urban uses that have environmentally detrimental effects. There are indications of Urban sprawl and city expansion in our Study Area of Kolkata indicating expansion of settlements and built-up area and thus causing environmental degradation in the city area. The process of urbanization always had signicant implications that can affect cumulative changes in demographic characteristics and/or transformation of the physical environment; unplanned, unsystematic and rapid urbanization can cause intense impacts on various environmental aspects, specically on land and air and water. A thorough understanding of the dynamic relationship between urbanization and its generated land-cover changes thus becomes completely essential for managing environmental changes and enabling sustainability of the environment and its resources.

Serang city is the capital city of Banten province surrounded by cities and counties nearby. At this time serang city has become center of activities and migration of the counties nearits that cause the past population growth. This of course will affect to the building both physical and non physical ones. At the same time environment problem increases too, such as the height of temperature , the increase of air pollution, trafkic jam, the decrease of water quality. One of the ways of handling the problems is bye keeping and developing green open space, that will become city forest. This research is to find out the potency of the impact of city forest management to envirounment in Serang city, like air quality. CO2 decrease, noise, moisture, and potency of carbon as well as potency of water absorbance. Research methodoly used is using primary data of environmental quality test in fivelocation in Serang city which is placed near the city forest area to colculate the potency of carbon absorbance using formula of biomassa tree calcution which is calculated based on the ability of plantation water absorbance. The research show that the value of physical environment in city forest area is better than the condition of physical environment which is forer from the city forest.

Urban shrinkage has become a common pathway (not only) in post-socialist cities, which represents new challenges for traditionally growth-oriented spatial planning. Though in the post-socialist area, the situation is even worse due to prevailing weak planning culture and resulting uncoordinated development. The case of the city of Ostrava illustrates how the problem of (in)efficient infrastructure operation, and maintenance, in already fragmented urban structure is exacerbated by the growing size of urban area (through low-intensity land-use) in combination with declining size of population (due to high rate of outmigration). Shrinkage, however, is, on the intra-urban level, spatially differentiated. Population, paradoxically, most intensively declines in the least financially demanding land-uses and grows in the most expensive land-uses for public administration. As population and urban structure development prove to have strong inertia, this land-use development constitutes a great challenge for a city’s future sustainability. The main objective of the paper is to explore the nexus between change in population density patterns in relation to urban shrinkage, and sustainability of public finance.

<p>City is a space that serves as a center place of activities, over time the city was experiencing growth and development, both physical and non-physical conditions. So these conditions affect the change in the pattern of land use, activity system as well as the pattern of people and goods mobility that are happening in the urban system. The phenomenon of the emergence of new urban areas (cities and towns) in IKK Gemolong causes changes in land use patterns along the road corridor is experiencing rapid development, it is evidenced by the increased activity and physical growth of the city. The conditions were observed with the growth of new activities such as residential, commercial district and other commercial areas. So that it will affect land use patterns, activities systems and people and goods mobility patterns that occur, which in turn will affect the characteristics of the spatial structure of the development of IKK Gemolong formed as a town in Sragen. The focus of discussion such as land use, population activity systems, as well as the people and goods mobility which the influencing factors of the formation of the spatial structure of a city. The study is considered important because as the basis for consideration in the development of towns in the future. This is because the policy of urban development continues in administrative and sectoral nature, so the presence of the regional autonomy policy of development with regional and integrated system and assessed more quickly to implement. This study used quantitative an quantitative study method. The analysis results indicated the characteristics of land use in Gemolong dominated by settlements, while the commercial district developed along the main streets of this town because Gemolong have function as service centers for its surrounding areas. The residents of Gemolong mostly have work in the non-agricultural sectors, such as trade and services, while the population as a farmer is relatively small, so that these conditions indicated that Gemolong says as urban area. The people mobility in Gemolong originated from both internal and external area of the town in destination location of commercial areas to have studying, working, shopping and other purposes. The residents of Gemolong do not have to big cities to access the daily life necessities for since it is already available in Gemolong. Based on the phenomenon of Gemolong have a compact city type of development, while the structure of urban spaces that were formed have view more functioning of each of the regions even though the condition is still occurring mixture of functions. Then, the structure of urban spaces is the type of sector, although not as ideal as yet which happened in developed countries.</p>
