Urbanization has brought rapid changes and transformations in many aspects of urban processes of many developing countries, including in spatial aspect, in the form of extended spatial formation of the cities into the surroundings, in order to meet the needs of economic and productive processes as well as those of social and consumption processes. Using the case of the growth of Surakarta Metropolitan, this paper aims to deepen understanding on the spatial process of urban population growth in the peripheries of secondary metropolitan that based on medium city size in Java, which is considered as one of the most densest populated in the world. The article will show the process of metropolitanization in Surakarta Metropolitan, in which influenced of its limitness of the administrative jurisdiction of the core area, the the growth extends into the surrounding areas. The analysis employs a time serial analysis by utilizing the national censuses population data from 1990 to 2010, The result shows that the urbanization process in Surakarta leads into a extended spatial form which also characterized by a fragmented phenomena. The spatial urban formation formed by such a process consist of a combination of some extensions of the previous urban areas and the formation of new urban centers that approached and merged one to each other in the long run. This process need to be understood as urbanization process is also a major contributors that shape the resource allocation and consumption of resources in the metropolitan and the surrounding areas. For Indonesia, the understanding of these processes will be very beneficial for the formulation of regional collaboration strategies in developing sustainable urbanization in the future.

Indonesia, as an archipelagic nation, has about 150 million people (60%) living in coastal areas. Such communities are increasingly vulnerable to the effects of change, in the form of sea level rise and stronger, more intense storms. Population growth in coastal areas will also increase the disaster risk mainly because of climate change-related effects such as flooding, droughts, and tidal floods. This study examines the dynamic changes of urban population and urban villages in three decadal periods, from 1990, 2000, to 2010. To highlight different disasters that are increasingly tied to climate change, the analysis was conducted in the northern coastal area of Central Java province using village potential (PODES) data, which are routinely collected by the government. Results show that about 41% of people in Central Java province live in the northern coastal region and 50% live in urban areas. The numbers of hazard events within a distance range of 0-40 km from the shoreline are: flooding (non-tidal)-335; tidal flooding-65; and droughts-28. Based on this study, about half of flood disasters (non-tidal) occurred within 10 km of the shoreline, while tidal flooding accounted for 80%. Most of the climate-related disasters were found in rural areas at low levels of population growth, while in urban areas the disasters were found to be associated in less than 1% and in more than 3% of population growth.
