Spatial Decision Support System For Solid Waste Management In Chickmaglur City

Abstract

The management of solid waste becomes more challenging in densely populated heterogeneous cultures in developing countries. The complexity of issues involved in municipal solid waste management necessitates development and application of new tools capable of processing data inputs of varying formats, numerical models and expert opinion in multi objective decision making scenario. Decision support system (DDS) is among the most promising approaches to confront such situations. After adoption of municipal solid waste (Management and Handling) Rules, 2000 in India, the necessity of development of an Environmental Decision Support System (EDDS) has further increased. The DDS models should ideally be integrated with Geographical Information System (GIS) to optimize collection, transportation, processing and disposal. For proper solid waste management it is necessary to know the quantity of solid waste generated, optimized route for collection of solid waste, selection of proper disposal site. The present study develops the model for solid waste management in chickmagalur city. It illustrates the quantity of waste generated in each ward, complete ward information is updated in Arc-GIS the database used are population, ward number, area under each ward, number of containers in each ward. New disposal site is selected with reference to CPHEEO guidelines using weighted overlay analysis database used are spatial and non spatial data which includes map layers such as soil, slope, drainage, topography, land use, contour, road network etc. Optimized path is developed using Arc GIS for selected new disposal site data base used in container location. This proposed model can offer a good decision support system which can be used by municipal authorities which gives complete information of each ward, provides highly suitable disposal site with less field work and cost, simple optimal routing model is proposed to achieve the minimum cost/distance/time efficient collection and transport path for municipal solid waste management.
