Analisis Kondisi Lingkungan pada Kejadian Leptospirosis di Kabupaten Banyumas dengan Pendekatan Spasial

Leptospirosis is still becoming a public health problem in Indonesia. Banyumas was oneof the highest cases in Central Java by 2019 so it could be potentially endemic. GIS (GeographicInformation System) is used to determine spatial patt erns related to the environment. This researchaimed to know the distribution and spatial grouping of leptospirosis in Banyumas 2019. The type ofthis research is an observational study with a cross-sectional spatial analysis design to observe thespreading and grouping patt ern. The subjects of this study were 140 leptospirosis cases in Banyumas2019. House coordinate was collected by using GPS (Global Positioning System). The data collectionis done for a month. Data Analyzes was performed through ArcGIS 10.2, and SaTScan 9.7. Thedistribution of leptospirosis in Banyumas was spread over 14 districts, 45% cases in Cilongok, 25,71%cases were >56 years old, 62,1% cases were male, 40% cases were farmers. The results of the spatialanalysis showed 77.14% cases in residential land use areas, 70% cases with moderate populationdensity (5.00-1.249 people/km²), 62.85% cases in 0-199 altitude, 63.57% cases with low rainfall 500meters, and signifi cant grouping patt ern with p-value = 0.009 primary which is located in Cilongokand Ajibarang. Leptospirosis spread over in residential land use areas, moderate population density,low altitude, low rainfall, no history of fl ooding, a radius of river 500 meters, and occurs clusteringin Cilongok and Ajibarang. The location intervention of leptospirosis prevention and control can beprioritized in these areas.

Geospatial Assessment of the Consumption and Absorption of Residential and Educational Land Uses of Zaria and Sabon Gari Area of Kaduna State, Nigeria

Human variables such as population increase and distribution, as well as economic expansion, have a strong impact on land usage. Zaria and Sabon Gari local government areas are endowed with various types of institutions that attract people from far and near to its space for studies and employments. This in turn leads to increase in population growth and the expansion of residential land use (LU). Thus, this study assessed the Land Consumption Rate (LCR) and Land Absorption Coefficient (LAC) of the residential and educational LUs using geospatial technique. The study analyzed Landsat imagery of 1987, 1999, 2006, and 2018. The study utilized a combination of quantitative (pixel-based) and qualitative (digitizing) methods of image classification for classifying the residential and educational LUs and biophysical covers. Quantitative assessment of the LU dynamics was achieved by the post-classification computation of LU dynamics, LCR, and LAC. The results revealed that residential LU occupied an area of 2594.25ha in 1987, 2815.15ha in 1999, 4042.54ha in 2006, and 8033.19ha in 2018. In the same vein, the educational LU occupied area of 2623.41ha in 1987, 2991.87ha in 1999, 3021.10ha in 2006, and 3093.75ha in 2018. The LCR values for residential LU were 0.555%, 0.468%, 0.579%, and 0.803% for the years 1987, 1999, 2006, and 2018 respectively. The LCR reduced from 1987 to 1999 and then increased from 1999 to 2018. The LAC values for the residential LU increased across the period of the study. The study concluded that the exploitation of the new lands for residential and educational LUs could be as a result of the demographic and institutional drivers of LU. The study suggested that the urban planning authority should develop planning measures that will regulate the already crowded residential LU in the study area.was transformation of rocky surface and waterbody into urban area, which was caused by population growth, human and agricultural activities in Zuru metropolis.

Domestic Cat Abundance and Activity Across a Residential Land Use Gradient

Free-ranging domestic cats are a detriment to wildlife and humans by preying on native species and transmitting disease. As a result, removing free-ranging cats from the landscape has become a conservation and public health priority. Estimating cat population size with an unbiased sampling design, however, especially in human-dominated areas, is logistically challenging and rarely done. The lack of robust cat population sampling limits our understanding of where cats pose risks, which is important for evaluating management strategies, such as trap-remove or trap-neuter-return. We hypothesized that cat abundance and activity both depend on human land use and demographics. Using a network of sites participating in a community science program, we conducted transect and camera trap surveys to test predictions of cat population abundance and activity across a gradient of residential land use intensity. Both sampling methods determined that cat abundance was greatest in areas with intermediate human population density and lower educational attainment. Transect data also provided evidence that cat abundance was greatest at intermediate levels of impervious surface cover (e.g., road and buildings), while data from camera traps also showed that cat abundance was positively associated with household income. Using counts of cats observed on cameras, we found that the timing of cat activity varied depending on the degree of urban intensity. Cats were more strictly nocturnal in medium and high intensity residential land-use areas, possibly because a greater proportion of these cats are unowned or because they avoid human activity. These results suggest that transect surveys conducted during the day may undercount cats in urban environments where unowned free-ranging cats predominate. Taken together, our results highlight the importance of incorporating human demographics, land use patterns, and urban context in estimating the abundance of free-ranging cats to better inform management decisions and improve conservation outcomes.

Scale Transition and Structure–Function Synergy Differentiation of Rural Residential Land: A Dimensionality Reduction Transmission Process from Macro to Micro Scale

In order to enhance the scientific understanding of the transition law of rural residential areas and enrich the theory and method system of land use transition research, this article takes Shandong Province as an example and constructs a comprehensive research framework of rural residential land scale, structure, and function from the perspective of the combination of the macro and micro scales based on differences between the rural residential areas in the region and the village scale forms. Using model quantitative analysis and horizontal comparative analysis methods, this paper explores the process characteristics of rural residential land use scale transition and the corresponding stage differentiation law of spatial structure and system function. Research has shown that the stage characteristics of the scale transition of rural residential land use in Shandong Province in the past 10 years are significant. The five transition stages—from the primary stage, low stage, intermediate stage, advanced stage, to the stable stage—show obvious spatial agglomeration and spatial autocorrelation, which are mainly driven by the positive and negative interactions of economic development, the policy environment, natural conditions, and population. With the gradual upgrading of the land use scale in rural residential areas, the spatial pattern of rural residential areas has been continuously optimized, the land use structure has tended to be balanced and complicated, and the living-production-ecological function as a whole has been strengthened. The essence of this type of differentiation is the differential performance of rural residential areas adapting their own conditions to the external environment. The transition of the rural residential area from the macro to the micro scale is also the process of realizing rural reconstruction and rural revitalization. In the future, under the framework of the “element–structure–function” system of rural residential areas, the rural transition and development should be continuously promoted through the support, organization, guidance, and promotion mechanisms of internal and external factors.

ASSESSING THE CURRENT IMPLEMENTATION OF TRANSIT ORIENTED DEVELOPMENT CONCEPT IN MALAYSIA: CASE STUDY OF MRT PUTRAJAYA LINE

In the past years, the concept of Transit-Oriented Development has been adopted in cities and countries including Malaysia and Singapore. The integration of land use and public transport stations through Transit Oriented Development (TOD) as part of urban and cities strategy is highly acclaimed in promoting sustainable development concept in cities development. To understand the performance of TODs implementation in Klang Valley, this study has selected eleven stations in of Mass Rapid Transit (MRT) Putrajaya Line as case studies. This paper aims to evaluate the current implementation of TODs in Malaysia, benchmarked against the TOD land use composition and percentage from Singapore’s model. The findings show that Raja Uda, Ampang Park and Persiaran KLCC stations show significant performance. However, Bandar Malaysia North station displayed poor result with the lowest percentage of residential and commercial components. All stations did not achieve the ideal TOD value for residential land use and eight out of eleven stations recorded higher than the ideal TOD value for roads. However, highest number of stations achieved the ideal TOD value for mixed-use and commercial land uses. These results would help policymakers to improve the current implementation of TODs in Malaysia.
