Abstract

The ability to better understand tropical peat ecosystems for restoration and climate change mitigation is often hampered by the lack of availability accurate and detailed data on vegetation cover and hydrologys, which is typically only derived from detailed and high-resolution imaging or field-based measurements. The aims of this study were to explore the potential advantage of airborne discrete-return lidar for mapping of forest cover in peat swamp forests. We used 2.8 pulse.m-1 lidar and the associated 1-m DTM derived from an airborne platform. The lidar dataset fully covered a 120 thousand hectare protection forest in Central Kalimantan. We extract maximum vegetation heights in 5-m grid resolution to allow detailed mapping of the forest. We followed forest definition from FAO for forest and non-forest classification. We found that lidar was able to capture detail variation of canopy height in high-resolution, thus provide more accurate classification. A comparison with existing maps suggested that the lidar-derived vegetation map was more consistent in defining canopy structure of the vegetation, with small standard deviations of the mean height of each class.

Abstract

Traditional markets function as trading place, socio-culture interaction, and recreation facility either in regional or urban scope. Distribution and variety of spatial condition influence traditional markets’ planning both physically and non-physically. Therefore, this research aims to conduct a mapping of traditional markets’ spatial distribution and variety as potential factors to improve spatial-based management. The research location is Surakarta City by applying analysis method including : 1) Mapping by employing Geographic Information System, 2) Category Based Analysis (CBA), and 3) Interactive Analysis. The result of this research signifies that spatial variety and distribution of traditional markets in Surakarta have similar pattern between one market to other markets; overlapping service function; specific commodity types in accordance with the market’s characteristics; diverse operating hours. Spatial variety and distribution could be potential factors to improve traditional market management as shopping service. It contrasts with Central Place Theory by Christaller and NÆss & Jensen’s research finding on distance which becomes a key factor influencing accessibility to a number of activity facilities. Therefore, distance toward the service center is not the main factor in traditional market management. However, the main factor in managing and controlling traditional markets’ development includes service function, commodity specification, and operating hours flexibility.

Abstract

Ambon City is the center of national activities in Maluku province, established under Presidential Decree 77 of 2014 about spatial planning of Maluku Islands. Ambon is a strategic region in terms of development of agriculture and fisheries sector. Development of the region make this area extremely vulnerable to the issues on water security. There are seven watersheds that affect the water system in Ambon City, which are Air Manis, Hutumury, Passo, Tulehu, Wae Batu Merah, Wae Lela and Wae Sikula. Therefore, this study was conducted to determine the impact of climate and land use change on water availability in seven watersheds in Ambon City. The analysis was performed by using a Soil and Water Assessment Tool (SWAT) Model to analyze climate change on the period 1987-1996 (past), period 2004-2013 (actual) and climate projection on the period 2035s (future) and analyze land use data in 1996 and 2014. The results of the research indicate that land use in the study area had changed since 1996 to 2014. Forest area decrease around 32.45%, residential areas and agriculture land increase respectively 56.01% and 19.80%. The results of SWAT model, present the water availability on the period 1987-1996 amount to 1,127.01 million m3/year and the period 2004-2013 decreased around 4.48% or to be 1,076.55 million m3/year. The results of the prediction of water availability in the future (period 2035s) estimated water availability in the study area will decrease water availability around 4.69% which is to be 1,026.09 million m3/year. The conditions describe land use and climate change has greatly contributed to the level of water availability in seven watersheds in Ambon City. Land use planning in the Ambon City really need to be considered especially in applying spatial plan. The forest area necessary to maintain. Land had developed into built-up area, it is necessary to implement of green space and water harvesting in order to maintain water security in the future.

Abstract

Surakarta is one of the rapidly growing Indonesian cities. The pressure towards its peripheral area is resulting ‘in-situ urbanization’ phenomenon of its rural village surroundings. Gentan is one of Surakarta adjacent rural villages that has been undergoing rapid spatial transformation from rural to urban settlement in the last 20 years (1995-2016). This research aims to clarify the spatial transformation in Gentan village through examinations in its spatial elements on higher resolution level; (1) transformation of its street network connectivity, (2) land use pattern, (3) building density, and (4) public facilities and accessibility. The data used is satellite imagery and staatistic data from several government institutions. The field survey were used in this research as sources for validation. From Gentan’s spatial elements observations, this research concludes that this village is transforming into urban settlements by its spatial elements characteristics. This research also provides interesting findings by its analysis on the neighborhood level that while Gentan is transforming into urban settlement, its internal connectivity is decreasing, residential uses dominated its land use, the village is dominated by the formal settlement, and the reach distance of its public facilities fluctuated across the time. So, it need more effective development policies to deal with such transformation.

Abstract

The impact of the climate change and global warming has hit the entire world, particularly the coastal areas such as the Dumai coastal area which is mainly caused by the sea level rise. Sea level rise is one of the important global issue today. It has been caused by ice melting at the poles, climate extreme event, and land subsidence. This increases the vulnerability effect in coastal areas which threatens human life, especially those living in coastal regions. Sea level rise can be forecasted by satellite imagery like ENVISAT, Topex/ Poseidon, Jason1 and Jason2. Sea level rise was calculated using a linear regression. Monitoring of sea level rise in the sea of Dumai was conducted over a period of 21 years (1993-2014) by taking data from 6 stations. The results show that the average sea level rise reaching 5.33 mm/year happened in Dumai. The rate of SLR lies between 4.72 mm/year to 5.66 mm/year. In 2050, Dumai, Riau is predicted to have an additional sea level of 0.19 m, 0.46 m in 2100 and 0.72 m in 2150. based on the predicted results, dumai should prepare plans to mitigate the rising of sea levels.

Abstract

Marine spatial planning has become the crucial issues for an archipelagic state such as Indonesia. The global market demand on marine economic species has been initiated the exploitation of the marine species which will become the hindrance in maintaining the sustainable marine biodiversity. Besides that, the degradation of marine species will also become the problem for traditional fishermen. Therefore, a model has to be employed to spatially manage the coastal waters as the alternative for fishermen activities during the closed season, such as floating fish net culture.  The aim of this study is to develop marine spatial planning model based on ecological approach to identify the potentiality of marine waters for marine culture such as floating fish net culture. The method for the model consist of social assessment using the Delphi for developing the rule of marine planning for floating fish net culture and the spatial analysis technique for determining the model of marine spatial planning for floating fish net culture. The area of Kupang Bay waters, East Nusa Tenggara was used as the study area. The result indicates that the model can be used to sustainable marine spatial planning, especially for floating fish net culture. The model considers the aspects of potential area for marine culture, the management of zonation and transportation lanes, the conservation and protected area and the strategic area. Application in Kupang bay illustrates the aspect of technology input such as raceways since the majority of the area of Kupang Bay waters is classified as medium potential. Further research still need to optimum the application of model to others marine area.

Abstract

Image-sharpening process integrates lower spatial resolution multispectral bands with higher spatial resolution panchromatic band to produce multispectral bands with finer spatial detail called pan-sharpened image. Although the pan-sharpened image can greatly assist the process of information extraction using visual interpretation, the benefit and setback of using pan-sharpened image on the accuracy of digital classification for mapping remain unclear. This research aimed at 1) highlighting the issue of using pan-sharpened image to perform benthic habitats mapping and 2) comparing the accuracy of benthic habitats mapping using original and pan-sharpened bands. Quickbird image was used in this study and Kemujan Island was selected as the study area. Two levels of hierarchical classification scheme of benthic habitats were constructed based on the composition of benthic habitats insitu. PC Spectral sharpening method was applied on Quickbird image. Image radiometric corrections, PCA transformation, and image classifications were performed on both original and pan-sharpened image. The results show that the accuracy of benthic habitats classification of pan-sharpened image (maximum overall accuracy 64.28% and 73.30% for per-pixel and OBIA respectively) is lower than the original image (73.46%, 73.10%). The main setback of using pan-sharpened image is the inability to correct the sunglint, hence adversely affects the process of water column correction, PCA transformation and image classification. This is mainly because sunglint do not only affect object’s spectral response but also the texture of the object. Nevertheless, the pan-sharpened image can still be used to map benthic habitats using visual interpretation and digital image processing. Pan-sharpened image will deliver better classification accuracy and visual appearance especially when the sunglint is low.

Abstract

Land provision is one of the biggest challenges for development in urban area. Most of the available urban land will be the object of speculation to be resold at a higher price when the time is right. In Jabodetabek, where the pace of urban development is faster than other parts of Indonesia, the prices of land are showing an abnormal increases; they seem to rise too fast. This paper discussing the increasing land prices in Jabodetabek area and argues that the increasing land price has encourages the private developer to bank the land in the area. Based on land price survey in Jabodetabek, urban activity is moving to south Jakarta. Parallel with the hypothesis, land price increase also trigger land banking practice in Jabodetabek which in total, reached approximately 60% of total area of Jakarta.

Abstract

Peat swamp area is an essential ecosystem due to high vulnerability of functions and services. As the change of forest cover in peat swamp area has increased considerably, many studies on peat swamp have focused on forest conversion or forest degradation. Meanwhile, in the context of changes in the forestlands are the sum of several processes such as deforestation, reforestation/afforestation, regeneration of previously deforested areas, and the changing spatial location of the forest boundary. Remote sensing technology seems to be a powerful tool to provide information required following that concerns. A comparison imagery taken at the different dates over the same locations for assessing those changes tends to be limited by the vegetation phenology and land-management practices. Consequently, the simultaneous analysis seems to be a way to deal with the issues above, as a means for better understanding of the dynamics changes in peat swamp area. In this study, we examined the feasibility of using MODIS images during the last 14 years for detecting and monitoring the changes in peat swamp area. We identified several significant patterns that have been assigned as the specific peat swamp ecosystem. The results indicate that a different type of ecosystem and its response to the environmental changes can be portrayed well by the significant patterns. In understanding the complex situations of each pattern, several vegetation dynamics patterns were characterized by physical land characteristics, such as peat depth, land use, concessions and others. Characterizing the pathways of dynamics change in peat swamp area will allow further identification for the range of proximate and underlying factors of the forest cover change that can help to develop useful policy interventions in peatland management.

Abstract

Flash-flood is considered as one of the most common natural disasters in Grenada, a tropical small state island in Caribbean Island. Grenada has several areas which are susceptible to flooding. One of them is Gouyave town which is located in the north-west of Grenada. Its land-use types are highly dominated by green areas, especially in the upper-part of the region. The built-up areas can only be found in the lower-part of Gouyave watershed, near the coastal area. However, there were many land conversions from natural land-use types into built-up areas in the upper-part region. They affected the decrease of water infiltration and the increase of potential run-off, making these areas susceptible to flash-flood. In addition, it is also influenced by the phenomenon of climate change. Changes in extreme temperature increase higher potential of hurricanes or wind-storm, directly related to the potential escalation of flash-flood. To develop effective mitigation strategies, understanding the behavior of flash-flood is required. The purpose of this paper was to observe the behavior of flash-flood in Gouyave watershed in various return periods using OpenLISEM software. It was used to develop and analyse the flash-flood characteristics. The result showed that the climatic condition (rainfall intensity) and land-use are influential to the flash-flood event. Flash-flood occurs in 35 and 100 years return period. Flash-flood inundates Gouyave’s area in long duration, with below 1 m flood depth. The flood propagation time is slow. This condition is also influenced by the narrower and longer of Gouyave basin shape. To develop flash-flood reduction strategies, the overall understanding of flash-flood behavior is important. If the mitigation strategy is adapted to their behavior, the implementation will be more optimum.
