To achieve these aims, a logical step has been carried out to complete this project. The structure of the research gives an idea of the issues covered in this project. 1.6 Methodology, in order to analyse the general waste management situation in the local authorities (Municipalities and District councils) in mauritius, a scientific approach was implemented to gather primary information which comprises of different steps. These steps are as follows: Step 1: The target group was identified.
Based on these information decisions appropriate decisions can be taken to improve the existing solid waste management system and also predictions can be made for summary future plans. Hence, in short the aims of this project are mainly as follows: to identify to what extent gis is being used in waste management in mauritius. To identify barriers to proper use of gis in waste management. To assess to what extent gis affects sustainable waste management as a decision support tool in planning waste collection, recycling, waste segregation and disposal. To carry out a case study for the Grand Port-savanne district council (gpsvdc) a local authority in mauritius in order to produce a database for decision making. The paper will also carry out a literature study of some examples of gis work for waste management. The study will include a discussion and a critical analysis of the models. The analysis of these studies will allow us to learn about the usefulness of gis as a tool is solid waste waste management and these may be developed for mauritius in the context of creating an Integrated Solid Waste management Plan. Further to literature review, a number of hypotheses have been designed and have been described briefly.
A gis map was prepared to serve as a zone management plan along with an environmental assessment that identifies cumulative pressures and impacts of some human activities on the village and the environment. A recycling program was developed based on solid waste sampling and analysis of collection systems. In a study carried out by bergeron. (2010 3d visualization and gis were used to produce a digital city model for the Star City, west Virginia to allow government officials and managers to manage assets and perform day-to-day operations, develop sustainable planning initiatives, and management of solid waste assets and facilities, planning. However, building and using a gis requires expert knowledge, and can often literature prevent such systems from being used to their full capability by local officials. In addition, local government is often comprised of mature citizens who are committed to serving their community but may be wary of new technologies that are unfamiliar to them. 1.5 aims and objectives, the aim of this paper is to analyse the extent to which gis is being used in waste management by the local authorities in mauritius, to identify barriers to proper use of gis in solid waste management and to assess. Finally a model will be proposed for the Grand Port-savanne district council (gpsvdc) a local authority in mauritius using Arcgis software that could be used as a decision support tool in planning waste collection and disposal. The model produced will be used to store information regarding the existing collection routes, land use data, population data etc and data regarding the volume of waste produced.
For example, ghose. (2006) proposed a model for the system of Municipal Solid Waste (MSW) collection that provides planning for distribution of collection bins, load balancing of vehicles and generation of optimal routing based on gis. According to reddy. (2007 traditional and static approaches are no longer adequate for analyzing network flows and conducting minimum cost routing. Attempted to develop a decision support system for generating an optimum route for solid waste disposal in Hyderabad City and hence to reduce the distance ran by the collection vehicle using gis. Gis tool provides an effective decision support through its database management capabilities, graphical user interfaces and cartographic visualization. The system developed by reddy. Used the network Analyst module available in Arcview, which is a path-finding program used to model the movement of resources between two points or more. Chatila (2008) developed a gis system for natural resources management and recycling of solid waste in the village of Marjeyoun in southern Lebanon.

However there are still some drawbacks and deficiencies in applying the method extensively. For example, it is not applied in solid waste generation studies because large fluctuations in solid waste generation by time and space and the dynamic nature of urban areas generate several difficulties in determining the current solid waste generation patterns. In the early period of gis technology, from the 1980's to the early 1990's, gis software was capable of executing only basic geographical operations. These capabilities of gis software limited the user to only basic tasks such as exclusion and allowed them to determine only alternative landfill sites in landfill siting applications. Advances in information technology and increasing access to computer systems by decision makers have improved the usefulness of computer models and computer aided technologies in dss in the last decade. One of the typical examples is the swm systems. The gis models do not only support the decision procedure but also facilitate your the communication and mutual understanding between decision maker and the people, because the implications of a swm closely affects the society.
However, the basic limitations in the use of gis in swm is the data availability. Because, especially in developing countries the available data are very scarce and access to the data is very poor and tiring. In addition, the existing data are not reliable, not collected, stored and disseminated systematically. More comprehensive researches and more efforts on data gathering to fulfill the needs of gis models are recommended. Since routing models make extensive use of spatial data, gis can provide effective handling, displaying and manipulation of such geographical and spatial information.
One is the waste management in the area where it is generated and second is the management of waste at dumping grounds." (moiz ahmed Shaikh, 2006). The development of geographic Information System (GIS) and its use throughout the world has contributed a lot in improving waste management systems. Gis helps to manipulate data in the computer to simulate alternatives and to take the most effective decisions. Gis can add value to waste management applications by providing outputs for decision support and analysis in a wide spectrum of projects such as route planning for waste collection, site selection exercises for transfer stations, landfills or waste collection points. Gis provides a flexible platform which integrates and analyses maps and waste management databases.
Gis allows us to create and store as many layers of data or maps as we want and provides various possibilities to integrate tremendous amounts of data and map overlays into a single output to aid in decision making (Chang. The changing production and consumption patterns have caused a rise in the volume of solid waste putting considerable pressure on governments in dealing with the increased waste generation. It implies that local authorities will require huge capital investments and operational strategies for collection, transportation and disposal of solid waste. Delimiting factors such as limited financial resources have made it imperative to replace existing ad hoc methods employed in solid waste management and planning (Vijay. (2005) studied the use gis in solid waste management in coastal areas as a decision support system with a case study on landfill site selection. The results of the study are that gis is becoming a powerful tool in swm.

Typically, a entry geographical Information System is used for handling maps of one kind or another. These might be represented as several different layers where each layer holds data about a particular kind of feature. Each feature is linked to a position on the graphical image on a map and a record in an attribute table. Gis allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts. A gis helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared. Gis technology can be integrated into any enterprise information system framework. 1.4 Uses of gis in Solid Waste management. Solid waste management comprises several phases, starting from the stage where the waste is generated till it reaches its final destination or at a stage where it is no more a threat to the environment. "It is observed that solid waste management can be bifurcated into mainly two phases.
(iii) quatre bornes, (iv) Vacoas/Phoenix and (v) Curepipe. There are also four District councils namely (i) Pamplemousses/rivière du rempart, (ii) moka-flacq, (iii) Grand Port-savanne and (iv) Black river. Solid waste collection and disposal is undertaken by these local authorities in areas under their jurisdiction and is disposed of at the mare Chicose landfill via a network of transfer stations situated in St Martin, roche bois, poudre d'or and la brasserie. Waste collection and disposal is also carried out by private companies on contract basis. The only landfill on the island is at Mare Chicose which is managed by a private contractor. With the increase in waste production the life span of the landfill is going on decreasing and soon there will be a need to increase the capacity of the landfill or to find another locality to set up a second landfill. The daily management of waste collection and disposal activities is carried out by officers of the health Department of the municipal councils and the district councils. 1.3 What is gis? Gis is a computer system for capturing, storing, checking, integrating, manipulating, analyzing and displaying data related to positions on the earth's surface.
The rapid industrialization and urbanization during the past decade have led to changing production and consumption patterns that continue to present new demands for natural resources and create new waste streams. It is expected that solid waste produced in mauritius is about 380,000 tons a year (or 1,200 tons per day) and is expected to reach 418,000 tonnes in 2014. The present strategy of disposing wastes at the landfill and/or dumping sites will in the long-run be no longer sustainable or appropriate with the rapid increase in waste generation, scarcity of appropriate landfill sites and the density of human settlement. The development of an integrated solid waste management strategy is among the priorities identified in the national Environmental Strategies to reduce future costs from environment degradation. Government's policy is to promote waste reduction, minimize its generation, encourage the adoption of environmentally sound methods of resource recovery and modernize the institutional and legal framework for the entire logistical chain - collection, storage, transfer and disposal - and introduce a cost recovery mechanism. "There has been awareness night regarding waste management amongst many countries. There has been development of new technologies for improving the waste management systems. Gis is one of the new technologies which have contributed a lot in very less time span to the waste management society." (moiz ahmed Shaikh, 2006). This paper analyses the benefits of using gis as a tool in solid waste management and makes an assessment of how far gis is being used by the local authorities in mauritius and identifies the barriers to the use of gis in solid waste management.

Print, reference this, published: 23rd March, 2015, solid waste management involves a number of stages starting from the choice of sites for landfill, collection, transportation and disposal of the solid waste. Both economic and environmental planners are concerned with the setting up of cost effective and environmentally friendly systems for solid waste management. Geographical Information System (GIS) is a tool that can provide spatial and non spatial information for urban planning and management. This paper focuses on the application of gis as a planning and data collection tool in Solid Waste management and analyses to what extent gis is being used in solid waste management by the local authorities in mauritius and also identifies the barriers to the. A gis model for the Grand Port-savanne district council (gpsvdc) a local authority in mauritius is produced using Arcgis software and this can be used as a decision support tool in planning waste collection and disposal. The republic of mauritius is a small island developing state (sids situated at 800 km off the east coast of Madagascar at longitude 58 East and latitude 20 south in the Indian Ocean with a total surface area of 1870. In addition to the island of mauritius, the republic includes the islands of Cargados Carajos, rodrigues and the Agalega Islands.
