Abstract

One of the pillars studies in sustainable development at the global level (SDGs) is a development environment. This pillar examines food security, sustainable consumption patterns and climate change. Climate change will affect agricultural activities. Climate change often causes experienced farmers crop failure because excessive rain or long summer season. The purpose of this study was to assess the effect of climate change on agricultural production. This study uses secondary data, that is rainfall data and agricultural production data as a baseline. This study examined descriptive statistics using maps, tables and graphs. The results showed a trend towards a decrease in agricultural production in all districts/cities. Based on regression analysis of the decline inagricultural production, namely cereals (rice, corn, cassava and sweet potato) is significantly influenced by changes in rainfall in all regions of the Province North Kalimantan except Tana Tindung Distict.

Abstract

AbstractLand use change is one of phenomena which have relation to various environmental issues.Global warming, loss of biodiversity and impact to human life are main issues related toland use change. Those issues have been drive international organizations to developparticular program to study land use change. One of the well known programs is Land Use/Cover Change (LUCC).Working group of LUCC suggested three core subject of researchrelated to land use change. Those are situation assessment, modeling and projecting andconceptual scaling.This research aimed to modeling dynamic of land use change based on spatial simulation.Integration of cellular automata and geographic information system were used to performspatial simulation. Modeling of land use dynamic was focused on conversion from agricultureland to non agriculture land. Three sub districts which are situated at urban fringe ofYogyakarta had been selected as research area. Those three sub districts were Depok,Mlati and Gamping.Time series of land use maps comprising year 1982, 1992 and 2000 as well as populationdata were used to generate input of spatial simulation. Several maps which denote qualityof land were used to develop transition rule. Results of simulation were spatial predictionof land use change for year 2001 toward 2007. It was then validated using land use 2007as reference. Validation test show that predicted and actual condition have fair agreement.

Abstract

Pekalongan is one of the coastal areas of Java Island that is affected by tidal floods. Tidal floods have various impacts on the social and economic conditions of the community, thus affecting their livelihoods. The purpose of this study was to examine the impact of a tidal flood, the socioeconomic characteristics of the community and the survival approach of coastal communities in Pekalongan. This study was conducted using a purposive sampling method in two villages in Pekalongan Regency, namely Jeruksari Village and Tegaldowo Village, because these two areas are affected by tidal floods. The study was conducted by using in-depth interviews and focus group discussions (FGDs), as well as structured interviews. The structured interview sample consisted of 60 respondents who were selected at random using quota sampling. The analysis was using qualitative-descriptive and quantitative methods. The gathered data were then presented in tables, diagrams and maps. The results showed that tidal floods resulted in physical, economic, sociocultural, health, educational, and environmental damages to the communities in both villages. The majority of the community members only have an elementary school education and primarily work as labourers. There is a difference in the amount of family income between the two villages, where the average family in Jeruksari Village has a higher income (IDR 3,465,300 per month) than the average family in Tegaldowo Village with total household income of about IDR 2 million per month. The most frequently used approach for survival in both villages is what is known as the survival strategy, i.e. a strategy to meet the needs of life at a minimum level to survive.

Abstract

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.
