AbstractGoogle Earth imagery is used here in conjunction with a Geographic Information System to identify transverse drainages and recreate palaeodrainage in an internally draining region in Iran. At least 35 water gaps and 34 wind gaps are shown to exist in the region, as well as evidence for an integrated palaeodrainage that originated north of the internally draining region and emptied into the Mand watershed to the west. The topographic characteristics of the transverse drainages suggest a strong control by local topography, and support formation of the internally draining region by basin filling and overflow. Both climatic and tectonic factors may have controlled the loss of external connectivity.

Seepage velocity is a very important criterion in infrastructure construction. The planning of numerous large infrastructure projects requires the mapping of seepage velocity at a large scale. To date, however, no reliable approach exists to determine seepage velocity at such a scale. This paper presents a tool within ArcMap/Geographic Information System (GIS) software that can be used to map the seepage velocity at a large scale. The resultant maps include both direction and magnitude mapping of the seepage velocity. To verify the GIS tool, this study considered two types of aquifer conditions in two regions in Iraq: silty clayey (Babylon province) and sandy (Dibdibba in Karbala province). The results indicate that, for Babylon province, the groundwater flows from the northwest to southeast with a seepage velocity no more than 0.19 m/d; for the Dibdibba region, the groundwater flows from the west to the east with a seepage velocity not exceeding 0.27 m/d. The effectiveness of the presented tool in depicting the seepage velocity was thus demonstrated. The accuracy of the resultant maps depends on the resolution of the four essential maps (groundwater elevation head, effective porosity, saturated thickness, and transmissivity) and locations of wells that are used to collect the data.

Nutmeg plant (Myristica sp.) produces seeds and mace as the main commodities of world spice trade. Nutmeg plant habitats in West Java are distributed mainly in Bogor, Sukabumi and Cianjur Regencies. This study aimed to determine the suitability of nutmeg habitats in three nutmeg production centers in West Java based on soil type and slope using the Geographic Information System (GIS) approach and Aster DEM (Digital Elevation Model) analysis. The study was conducted from August to December 2018, by collecting data of: a) The coordinates of the area planted with nutmeg using GPS (Global Positioning System), b) Field documentation in the form of descriptions around the data collection point, c) Soil analysis data, d) Land area data, e) Map of the earth scale of 1:50,000 scale from the Geospatial Information Agency, and f) Landsystem map of West Java scale of 1:250,000. Data were analyzed using Arc GIS 9.3. The results of land suitability analysis based on rainfall data for Bogor region was classified in the category of marginally suitable (S3), while the regions of Sukabumi and Cianjur were sufficiently suitable (S2). Temperature of Bogor region was categorized as the most suitable (S1), while Sukabumi and Cianjur regions were sufficiently suitable (S2) for nutmeg development. The distribution of nutmeg was in Latosol and Regosol soils, with soil pH of rather acidic (pH 4.78-5.98), clay texture, low to high C-organic content (1.5-4.5%) and moderate to high N-Total (0.2-0.5%). Cation exchange capacity ranged from 25-30 cmol(+)/kg with a base saturation level of around 55-60%. Based on slope, the distribution of nutmeg in the West Java region was in the range of slope with a flat (<8%) to sloping (8-15%) category, with altitudes between 400-900 m above sea level classified as suitable to very suitable for nutmeg development. The overall agroecological suitability of nutmeg plants in three nutmeg production centers in the West Java region was classified as suitable to be managed and developed

Japan has traditionally been seen as an “isolated” country, often excluded from analyses of Asian trade and even ignored in its maritime influence on domestic trade. Examining both documentary and archaeological evidence in the late medieval periods (fourteenth to sixteenth centuries) reveals a thriving trade network of both domestic goods and items from the mainland. Analyzing this data through a Geographic Information System (GIS) provides important information about the transshipment hubs, the multidirectional flow of trade items between communities in the Inland Sea, and even the labor patterns of the captains that plied those waters. Those trade patterns were also influenced and used by domestic “pirates,” sometimes referred to as “sea lords,” who controlled certain areas in the Inland Sea. They were able to procure items for their own use, possibly outside of legitimate trade channels. The thriving domestic maritime trade revealed through this analysis paints a fuller picture of the networks within the Inland Sea before Japan’s contact with the West.

This study aimed to develop a Geographic Information System (GIS), for storage of information and geographic location of apiaries in eight counties in western Paraná; study the local flora; the land used; and the honey productivity in the harvest of 2010 in two of these areas: Marechal Cândido Rondon and Santa Helena. In order to do so we used the software SPRING, delimiting a radius of action of bees of three kilometers around the apiaries. We interviewed and registered 126 beekeepers with 383 apiaries. By using the images we selected areas with greater and lower overlap of hives in Marechal Cândido Rondon (144 and 44 hives, respectively) and Santa Helena (165 and 40 hives, respectively), in a three kilometers radius, selecting 15 colonies in each area, for the study of the parameters cited. In the multivariate analysis of the grouping, five groups were formed, by their similarity of management, indicating the higher average production in the hives of the most populated area of Santa Helena and lower average production in the most populated of Marechal Cândido Rondon. The grouping of hives, the differences in the production of honey and floristic survey indicated that these differences could be associated with management, floristic and climatic differences recorded in the period of production, in the areas studied.

Lulc Change

The need for built-up area increases along with a rise in population growth in many regions. This phenomenon leads to a tremendous change in agricultural land and decrease in the environmental carrying capacity. Therefore, this study aims to determine Land Use and Land Cover (LULC) dynamics and the drivers used for its modeling in 2030. This is a quantitative study, which uses the dynamic models of Geographic Information System (GIS) and Markov-CA. Data were obtained from the CNES-Airbus satellite imageries in 2009, 2014, and 2019 by using Google Earth at East Cirebon. The drivers include road density, distance to CBD, total population, distance to settlements, land slope and distance to rivers. The interaction between drivers and LULC change was analyzed using binary logistic regression. The results showed that the rise of built-up area reached 36.4 percent and causes the loss of 0.78 km2 of agricultural land from 2009 to 2019. The LULC simulation in 2030 shows an increase in the built-up area by 82.85 percent with probabilities above 0.6. Meanwhile the significant drivers for changes include road density and distance to settlements. In conclusion, efforts to reduce LULC change in agricultural land into built-up area is by re-strengthening spatial planning-based environmental awareness for the community.
