    Identifying Municipal Solid Waste Dumping Site Location Using AHP and GIS Techniques: A Case Study of Coimbatore District, India
    (Springer, 2022) Aishwarya, V.; Salma, S.; Dodamani, B.M.
    Increased municipal solid waste generation in urban areas is a result of fast population growth and urbanization. Dumping or landfilling in unsuitable areas becomes the biggest concern for solid waste management authorities. The present dump yard at Vellalore, Coimbatore district, affect nearby settlements with a foul stench and flying ashes due to strong winds. The study’s main goal was to provide alternative landfilling sites in the Coimbatore district using GIS and analytic hierarchy process (AHP) techniques. Nine criteria were considered. These were population density, slope, geology, geomorphology, land use/land cover, and proximity to road, river, railway, and airport. Weighted overlay, a spatial analyst tool that reclassifies raster maps and a final suitability map, is generated. According to the findings, the possible landfill zones were found in the northeastern region of Coimbatore. Hence, the environmentally suitable sites can be selected by using remote sensing and GIS techniques. © 2022, Indian Society of Remote Sensing.

    Preparedness for a forgotten disaster: A case study Coimbatore, India
    (Elsevier Ltd, 2024) Lalith Prakash, E.; Anand, K.B.; Kolathayar, S.
    Earthquake preparedness is known to effectively reduce the distressful effects of earthquakes, as demonstrated in experiences worldwide. This research aims to use a region-specific, valid, and reliable survey-based tool to assess individual and community earthquake preparedness levels in a densely populated city region with a forgotten earthquake history. The study focuses on evaluating the earthquake preparedness levels of a population in the Indian peninsular shield region that has not experienced an earthquake or received any preparatory program in their life time; but the region has an earthquake history. Coimbatore city was chosen for the same reason, and two survey-based tools were developed - the Individual Earthquake Readiness Index (IERI) and the Community Earthquake Readiness Index (CERI) - using a comprehensive literature analysis, questionnaire creation via focused group discussion followed by expert panel validation, and pilot studies. This study ensured the validity and reliability of the tools through content validity, construct validity, internal consistency test, Spearman's test-retest reliability test, Exploratory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA). The final IERI is a 27-item tool, and the final CERI is a 20-item tool. This study broadens the scope of risk assessment, facilitating a methodical estimation of Earthquake Readiness Index as one of the pivotal social vulnerability determinant. The study revealed a strong sense of community spirit in Coimbatore, but residents showed a lack of individual preparedness and were hesitant to take leadership roles. The findings emphasize the need for targeted interventions to bridge the gaps in earthquake preparedness, fostering a culture of proactive engagement and individual responsibility. © 2023
