Detection and Delineation of Potential Areas for Tourism Activities in Coastal Zone of Ratnagiri District, Maharashtra (India)

Tourism is a device of economic development in developed, developing, and even in underdeveloped countries. The AHP based MCDA techniques used for detection and delineation of the tourism potential zones in the coastal area of Ratnagiri district in Maharashtra (India). The conventional and satellite data viz. ASTER data has been used for spatial analysis in GIS software. Seacoast, elevation, slope, river, LULC, available amenities, accessibility and connectivity, cultural and historical places, and density of settlements used as the criterions for detection of potential zones for tourism activities. The experts’ opinions, literature survey and fieldwork used as the source of information for the selection of criterions and determination of ranks. The weighted overlay technique used to find the comparative levels of tourism potentials: very high, high, moderate and less potentials for tourism. About 13% of TGA shows comparatively very high tourism potential, 25.80% shows high, 54.62 % shows moderate, and 6.57 % shows less tourism potential. The overall accuracy of the categorized map estimated about 89.60%. The thematic maps viz. amenities and settlement were processed using inverse distance weighted (IWD) interpolation technique. Therefore, some areas from the category, ‘high potential’ merged in the category, ‘moderate potential’ and reduced the producer’s accuracy of the classified map. The sandy beaches, lowland area with a gentle slope, river landscape features, road network, cultural and historical places, ideal size of settlements and number of amenities are attractions of tourists in the region. The technique used in this study can be an effective apparatus for precise analysis of site suitability for tourism activities.

Riverfront Development - A Public Realm, Its Adaptations, and Environmental Impacts

Sidemen Distrct is one of the tourist attractions in Karangasem Regency. One of the prominent tourist attractions in Sidemen District from the past until now is the natural attractions of Iseh and Tebola as well as the sidemen songket weaving craft centre. Then, in 2010 began to expand tourism with the concept of “river tourism” namely tourism by making the Tukad Unda river as the main attraction. The development of tourism in Sidemen District is increasingly felt by the emergence of various tourism supporting facilities in the river border area. Of course, with the development of the construction of these facilities, it has an impact on the environment in the river border area, especially the spatial function seen from land use. The method used in this research is mapping analysis method with overlay technique. The results of the analysis explain that changes in land use that occur are clearly visible from the year of observation, namely in 2010 before the construction of tourism facilities until 2021. Changes in land use that occur lead to incompatibility with the direction of land use that has been determined. There are several land functions that have changed, including the function of plantation land/moor, and the function of agricultural land/rice fields. Of the two land functions, the one that shows the most changes because it is used for tourism facilities is the plantation/moor function of 5.43%. This percentage of land use change area is evidence that an activity such as tourism can have an influence on land function in an area. If this is left unchecked, it can result in arbitrary land use and not in accordance with the direction of the land function designation that has been stipulated in the spatial planning rules.

Mapping of Vegetation Development Zone to Enhance the Coastal Community Resiliency

Climate change has implications for the environment and community such as the existence of climate-related disasters. The changes of weather cycle triggers flooding in coastal areas, then high water discharge eroded the soil and caused landslides. Land conversion of upstream area causes low water absorption and high run-off which also contributes to flooding and landslides in the downstream area. Efforts to normalize rivers and urban drainage have not been able to cope with floods and landslides. Therefore, it needs an effort to minimize these disasters. The vegetative approach is an alternative for mitigating floods and landslides that are considered more comprehensive which not only conserves landscapes but also contributes to increasing green open space provision. This study aims to analyse the possibility of applying a vegetative approach to improve the physical and socio-economic community’s resiliency in coastal areas from climate-related disasters. The research method used a quantitative method with data collection techniques through literature studies, field observations, and questionnaires. The data processing stages include analysis of the physical condition to determine the physical vulnerability of the area through the physical natural map overlay technique; analysis of the climate-related disasters impact on society through descriptive statistical analysis techniques; and analysis of the possibility of applying the vegetative approach by using spatial analysis techniques to determine the level of vulnerability and priority zones for vegetation development.

Building age profile and figure-ground image: defining the urban development pattern of Balikpapan City

As one of Indonesian city that emerged from the industrial sector, Balikpapan grew and was inhabited by transmigrates from various cultures. The development and growth patterns of the Balikpapan urban area was influenced by the culture of the residents, due to the absence of empire influence or colonialism. This research was conducted to identify the oldest area as a starting point of the urban development patterns of Balikpapan. The building-age profile method was used to identify the oldest building groups or blocks, which belong to the city’s heritage zone. In this analysis, a series of figure-ground images in several periods were collected to indicate the building age. Through the process of overlaying solid-void maps, the pattern of space-built interaction was generated as the patterns of urban development. Results shown that urban development, which was determined through overlay technique, was organic pattern, which was formed by several connected irregular shapes. The conservation of the urban pattern indicates the effort to achieve urban identity, as one of the sustainable urban form indicator.
