The pattern of the land, natural resources and environment used will influence the sustainability of a city. Nowadays, many cities in Indonesia have been developed without consideration of ecological aspects. The development of built areas that tends to be sprawling and convert natural environments such as forests and other green areas, wetlands, and lakes that have ecological functions has been causing the increasing environmental problems such as floods, groundwater shortage, and micro climate change in many cities. Spatial planning that considers thesustainability of ecological functions is a strategic tool to manage the city’s land allocation so as to achieve sustainable cities. However, most spatial planning products of cities have been made without the support of ecological data and analysis in the planning process. The paper discusses the importance of maintaining the ecological spaces as a part of an urban ecosystem and decribes the concept of sustainable spatial planning, including data and analysis should be prepared in order to integrate ecological consideration in the sustainable spatial planning process.

The concept of carrying capacity of water resource is applied as amanagement tool for the operationalization of sustainable regional planning.Carrying capacity of a region, comprising its supportive and assimilativecapacities, is defined as the ability to produce desired outputs from a resourcebase to achieve a higher and more equitable quality of life, while maintainingdesired environmental quality. The proposed conceptual model for thecarrying capacity-based planning process considers problems, constrainingand supporting factors, and interrelated systems within a dynamic ecosystemto arrive at the water resource-based sustainable regional planning.

Urban green space plays several roles in balancing the urban ecosystem and maintaining the environment sustainability. Firstly, the urban green space plays a valuable role in prevention of flooding. Trees restrain the movement of sediment and run off. Secondly, the urban green space plays an important role in water conservation, since the tree’s roots absorb some excess water from the soil, making the soil drier, and are able to store morerainwaters. Therefore, the analysis of natural capability of a region in water conservation and flood prevention should become the basis to produce sustainable spatial planning. A study of the importance of green space in maintaining environmental balance in Batam, Malang and Muaro Jambi were conducted by P4W-IPB and P3TL-BPPT by applying the Kato model withsome slightly modifications, to map and evaluate the natural capability of those areas on water conservation and flood prevention. The model is based on validated land evaluation models and ecological value, and mapping the differences between the land covered by green space and that by abandoned areas. Evaluation of the ecological functions of urbangreen space, in combination with other parameters, has been done under GIS and Remote Sensing. The spatial analysis of the ecological function within three areas showed different figures, in which the that 38.12 % of Muaro Jambi, 35.22 % of Malang and 13.36 % of Batam, were functioning properly for water conservation, while 57.71 % of Muaro Jambi, 37.01 % of Malang and 23.75 % of Batam were functioning properly for flooding prevention.

Urban and regional development needs space and land which then replaces the existence of natural space. The loss of natural space does not give negative impacts as long as it does not exceed ecological carrying capacity.Unfortunately, urban and regional development in Indonesia is dominated by economy motivation than ecology consideration. As a result, several natural disasters occurred such as flood, ground water depletion, land slides etc. Our research objective is to analyze land cover change from natural space to human activity space and several factors which cause it at 4 different regions: Malang Municipal, Batam Municipal, Pemalang Regency and Muaro Jambi Regency. Research result could be used as basic information for local government to arrange planning, use and control spatial change in each area. This research was conducted by using two different time data images with interval 10 years to get land cover change on each region and social economy data from National Statistic Bureau. The model was formulated by using forward stepwise multiple regressions and the result showed that each region has different factors which increase land cover change of natural space such as: (1) Malang Municipal was dominantly influenced by urban sprawl phenomenon, (2) Batam Municipal wasdominantly influenced by government policy to develop industry, (3) Pemalang Regency was dominantly influenced by appearance of several new growth poles, and (4) Muaro Jambi Regency was dominantly influenced by land necessity for agriculture activities.

Regional Spatial Planning (RTRW) of a city or a region becomesimportant due to limitation of land, while land necessity is increasing. Inorder to achive the sustainable city / region, the attention to naturalcapabilities on water conservation and flood protection should be adaptedon RTRW. The RTRW should prevent the exsisting capabilities andincrease when the capabilitis are less. Using simulation of model as tool of analysis in the spatial planningprocess, we can see the city/ region capabilities on water conservation andflood protection, and then make decision on spatial use of the city / region.The simulation in this study was applied in the City of Batam, which wasfocused in Batam Island by using data on the year of 2000. The results ofthe simulation shows that regions which are categorized as having high andvery high capabilities on water conservation occupied only 13,36%, whilethose that have high and very high capabilities on flood protection is about23,75% of the island area. By applying of reboisation scenarios, theregions that have high and very high capabilities on water conservation canbe increased to become 56,97% and those that have high and very highcapabilities on flood protection increase to 53.58% of the island area.

Modern life and modern technology require vast use of energy. The use ofenergy in the cities has been dramatically escalated within the last decades. Since most of energy consumed by people live in urban areas is from the non-renewable resources like fossil fuels, we will certainly face problems of energy crisis and global warming to sustain our cities livable in the future. Due to the moderate prevailing climate conditions, which are close to the comfort temperature, less energy will be required to modify indoor temperature suitable for human indoor activities. Since the dependency to the energy is small, people in the humid tropic may have better chances to sustain their cities livable in the future. However, most of Indonesian cities are designed in such away with little consideration to some important design factors as climate, environment, energy, green transportation and an adequate infra structure, like urban drainage. In return, many cities are nothealthy and convinience to be lived for and are not in line with the sustainable design approach. This article provides some discussion on how tropical cities in Indonesia must be planned and designed toward sustainable built environment. Energy as the main role in sustaining our built environment is taken as a priority here to be considered in designing our humid tropical cities of Indonesia. This is in order to achieve sustainable living environment for our future generation and us.
