Comparative assessment of the models showed that the SEMSLR and the spatial error models were the best models. The spatial effect from the various spatial regression models was statistically significant, indicating an essential spatial interaction among neighboring geographic units and the need to account for spatial dependency in obesity research. The authors also found a statistically significant positive association between the percentage of families below poverty, Black population, and SNAP recipient with obesity rate. The percentage of college-educated had a statistically significant negative association with the obesity rate. The study shows that health outcomes such as obesity are not randomly distributed but are more clustered in deprived and marginalized neighborhoods.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45153978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aims to evaluate the performance of built‑up delineation index set (BDIS) for mapping agricultural land loss in Upper Egypt. Three Landsat images were obtained for the years 1986, 2000, and 2016 and utilized as inputs to calculate the BDIS variables. Then a supervised classification technique (i.e., support vector machine) was used to classify the images. The findings showed that urban areas have witnessed a dramatic expansion at a growing rate of 44.1% during the 30 years. As a result, the loss of the agricultural land was found to be approximately 64.83 ha, which represents -4%, during the same period because of the urban expansion and the illegal construction of settlements. These findings would support the local decision makers in urban and agriculture land management authorities to develop sustainable development plans that control the spatiotemporal urban expansion and agricultural land loss.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42379373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Composite soil samples collected from the plow layer at 272 nodes on 15 x 15 m grids were analyzed for texture and bulk density. These values were used as pedotransfer functions to predict unsaturated (Ko) and saturated hydraulic (Ks) conductivities as well as the van Genuchten curve shape parameters α and n. Regression analyses quantified relationships between the measured and model predicted soil properties. While correlations between textural and model predicted soil properties including bulk density were significant (p<0.05), those between sand and clay, clay and n, clay and α were not. Sand and silt appeared to be better predictors of soil hydraulic conductivity and the van Genuchten curve shape parameters for the soil investigated.

The study used Landsat satellite imageries of 1986, 1998, 2007, and 2017 and population data to analyze land cover and use changes of the two watersheds. A decline in natural vegetation cover by 57% and 71.3% has occurred for Owabi and Barekese watersheds respectively. Cropland increased by 77.1% and 105.2% while settlement has increased by 1,018% and 4%, respectively, for Owabi and Barekese watersheds. Cropland is the main form of land-use change for Barekese watershed while settlement is the main land-use change in the Owabi watershed. Annual expansion of settlement within the Owabi site was 38.1%, and cropland was 5.2% for the Barekese site. Population trends had a significant negative relationship with forest cover and a positive relationship with settlement and cropland.

The study used both qualitative and quantitative approaches to collect data and household spatial position recorded by the global positioning system (GPS). The findings show that an average of 95.8% of fishers knew seaweed and 86.5% were willing cultivate it. A chi-square test shows no significant association between gender, age, education, distance, and the willingness of fishers to participate in the seaweed cultivation. In a regression model, only age group between the ages of 18 and 64 have a strong effect on the willingness of fishers to grow seaweed (P<0.05). However, focus group interviews with fishers indicate that women are not allowed to engage in any offshore activities at Ayitepa/Kponor, Ngyiresia, and Adjoa. This study shows that gender and age are main factors in deciding human capital for the cultivation of seaweed in Ghana.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48201841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research integrated RUSLE into GIS to estimate the annual soil erosion rates for the Northern, North-East, and Savannah Regions of Ghana. A soil erosion map was generated with an annual soil erosion rate of 4.0 t ha−1y−1 for the Northern Region, 5.0 t ha−1y−1 for the North-East Region, and 7.0 t ha−1y−1 for the Savannah Region. Relatively higher erosion rates were observed in the Tatale Sangule and Kpandai districts of the Northern Region, with rainfall erosivity being the main driving factor. There was a landuse/cover erosion reduction effect of 66% in the Northern Region, 70% in the Northeast Region, and 58% in the Savannah Region.

Using a variety of unconventional web-based data sources, the authors use correlations, mapping, and regression analyses to find that while crime generally associates negatively with property values, not all crime-types have similar effects. Lower incidence of violent crimes and sex offenders in neighborhoods can have pronounced positive impacts on property values whereas certain types of property crimes gravitate toward neighborhoods with expensive homes. Further, crime rates may be similar or even higher than those in cheaper/disadvantaged areas. These types of offenses do not necessarily follow the price-dropping effect like other crime-types do on housing values. However, property crimes such as thefts do not follow this trend. They, thus, recommend that property crime alone should not be a factor when making decisions concerning home buying and/or where to live.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":"12 1","pages":"57-75"},"PeriodicalIF":0.5,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47257613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
