Recently, food security becomes a priority for many governments particularly in developing countries. Food security has four dimensions i.e. availability, accessibility, stability, and utilization. This study examined food accessibility in term of geographic access i.e. the contribution of the geographic environment to food choices and consumption. The study located in Tanjung Selor Subdistrict, the capital region of Bulungan Regency as well as North Kalimantan Province. Geographic access to food was analyzed based on spatial distribution of food stores, settlement, and availability of transportation network. Spatial analysis, i.e. coverage, density, and network analysis, as well as the spatial visualization were performed using tools available in GIS software. This study revealed some circumstance related to geographical access to food in the study area. Geographical access to food for non-motorized people is limited. Non-motorized people have to walk more than 1 km to the nearest food store. Access to food for motorized people is somewhat different. Their geographical access, in general, were categorized as easy to moderate. This situation indicates that the availability of public transport or vehicle ownership is necessary to improve access to food.

The population and economic growth increase the need of space leading to an increase in built-up area. There is an increased activity in the city centre which results in the residents feeling less comfortable to live in the area. Hence, the growth of the settlement area tends to head towards the periphery. This condition is an indication of the developments of the built-up area in the periphery. Urban sprawl is a phenomenon of development of an irregular built-up area which leads to the suburbs. Urban development as a result of urban sprawl will trigger an increase in the demand for supporting facilities and infrastructure. An urban Sprawl in Semarang City has resulted in the establishment of residential areas in a conserved region, which is against zoning regulations in the Semarang City Spatial Planning Document (RTRW). Urban Sprawl Typology Research in Semarang City aims to analyse the urban sprawl typology in the city. By knowing the typology, it can minimise the impact of urban sprawl. This research was conducted using the remote sensing method and geographic information system (GIS) with the Shannon's Entropy approach. The results indicated that in 2006 and 2016, urban sprawl in Semarang City had three types of typology that can be classified as typology I (low level), typology II (medium level) and typology III (high level). The impact of urban sprawl on typology II and III can be minimised through the provision of affordable housing with adequate infrastructure, and an improvement in the permit system for housing and settlement development.

Semarang Coastal has a high level of vulnerability to inundation, river flooding and tidal flooding. To solve the problems, a region has an adaptive capacity to the phenomena encountered. The aims of study to map the level of vulnerability and adaptive capacity of the region in facing the phenomenon and provide an alternative strategy in facing the impact of inundation in coastal areas. Based on capacity index and vulnerability index in 2015, most urban villages are located in quadrant 3 (58 villages), in quadrant 1 (36 villages) and quadrant 4 (5 villages). the results showed that most of villages located at coastal areas had a high vulnerability with low adaptive capacity. Considering spatial planning (RTRW) for 2030, population density changes, Semarang City Facility health facilities Plan in 2030, and the open areas as defined in the Semarang 2011-2030 spatial plan (RTRW) a major shift towards the quadrant 2 was observed, suggesting an increased capacity to encountered inundation susceptibility.

Geographical Information System (GIS) modelling using vector data is a commonly used method of modelling offering simple data input and analysis. However, the vector-data model assumes homogeneity in mapping units based on subjectively applied classification and simplification, and this may lead to over-simplification and consequent reduction in the variety of information obtained and uncertainty in results. This research aimed at refining the suitability modelling for sea cucumber (Holothuria scabra) using fully raster-based data for the waters of Kiowa Bay, Kahyapu village in the district of Enggano, North Bengkulu, Indonesia. Using a GIS, all parameters affecting suitability for sea cucumber were rasterised to improve compatibility. The relevant data includes nine parameters of sea water namely acidity, depth, current velocity, temperature, salinity, brightness, dissolved oxygen concentration, condition of the sea floor, and coastal protection of the area. These parameters were surveyed in the field at 51 stations and each parameter was then digitized and interpolated (using Kriging method) to create a continuous raster-dataset. Correlation analysis was then conducted to check parameter correlation. Parameters with a correlation coefficient of > 0.75 were excluded from further analysis since results could be derived from the remaining parameter set. Principal component analysis (PCA) was then applied to ascertain the weight of each component. Furthermore, scree plotting was employed to choose which principal components were relevant for insertion into the formula of suitability. The final result was then compared to the map of suitability from the analysis of vector-based data as the reference data set. The research results showed that this method can be used to locate areas that are suitable for sea cucumber farming. The suitability map for sea cucumber generated from the analysis using fully raster-based data displayed less uncertainty than the suitability map generated using vector-based data.

The south coastal region of Yogyakarta Province (YSP) in Indonesia has inherited a unique farming system called sawah surjan, which is considered as a cultural heritage that demonstrates a form of local wisdom in managing land resources with poor drainage. The local residents have succeeded in realizing their desire of making the farming system ecologically stable and capable of providing a decent living. As a cultural heritage, however, sawah surjan has been under an increasing threat of conversion resulting from the infrastructure development and spreading of urban developments. This study assessed the prospect of sawah surjan in the rural household economy and its sustainability within the context of changing wider environment. To do so, a household survey was conducted covering 41 farmer households in Depok Village, Panjatan Sub-district, Kulonprogo Regency, Yogyakarta Special Province where the existence of sawah surjan is threatened by the large-scale investments. The research show that sawah surjan contributes to employment generation, diverse sources of income, food security, and income redistribution. It is generally sustainable but the excessive use of pesticides and chemical fertilizers will have adverse effects on its sustainability. The research confirms that the most significant threat is the infrastructural development, especially the prospective construction of a new international airport as increased land prices may lead to uncontrolled conversion of sawah surjan into non-agricultural uses. This is also in coincidence with the stagnant regeneration of farmers in the area that lead to a bleak future of the system.

Kulon Progo has been struggled to cope with the issues of poverty and food insecurity. The provincial and local governments pay a lot of attention to tackling these deprivation problems. The BKPP DIY developed a composite index which concluded that poverty is the primary cause of the deprivation. Therefore, this paper aims to explore the rural deprivation in Kulon Progo by assessing its aspects including poverty, food insecurity conditions, livelihoods, and local food potentials. Several methods, including typology, livelihood calculation, and resource possibility mapping are introduced for the preliminary analysis of this deprivation. The findings show that in Kulon Progo, (1) most of the deprived areas are located in the typology of upland region, (2) based on its of five assets, in general, the livelihood condition in Kulon Progo needs an improvement on financial, natural, and physical capitals, and (3) presenting the local food clusters based on its local food plantation area and production, so that these findings could give alternatives for the decision makers to develop the rural (deprived) areas.
Kulon Progo一直在努力解决贫困和粮食不安全问题。省级和地方政府非常重视解决这些贫困问题。BKPP DIY开发了一个综合指数，得出的结论是贫困是剥夺的主要原因。因此，本文旨在通过评估贫困、粮食不安全状况、生计和当地粮食潜力等方面来探讨库隆普罗戈的农村剥夺问题。介绍了几种方法，包括类型学、生计计算和资源可能性映射，对这种剥夺进行了初步分析。研究结果表明，库隆普罗戈(1)大部分贫困地区处于高地地区类型;(2)从其五项资产来看，库隆普罗戈的生计状况总体上需要从金融资本、自然资本和物质资本三个方面进行改善;(3)根据库隆普罗戈当地粮食种植面积和产量，呈现出当地的粮食集群，从而为决策者提供发展农村(贫困)地区的选择。
