Error Involved in Estimation of Site Sensitivity Index (SSI) for Land filling of Municipal Solid Waste
Author(s)- Anurag Ohri., P.K. Singh
An environmental Index known as Site Sensitivity Index (SSI) was developed by Central Pollution Control Board (CPCB) in association with NEERI, India to quantify and compare the sensitivity of different sanitary landfill sites on the basis of accessibility, receptor, environmental, socio-economic, waste management practices, climatological and geological criteria. The SSI integrates parametric effects of all attributes about suitability of site for landfilling and generates a single number expressing the sensitivity of the site for municipal solid waste disposal. The index is based on the impact of 32 attributes and their relative significance as assessed by a group of experts. It therefore necessitates ascertaining all 32 attributes for the selected sites and then compare their respective suitability based on SSI. In case, data related with any or a few attribute(s) are not available, comparing and finalization of landfill site is not possible using this approach. This paper attempts to estimate and report the error introduced in the value of SSI due to unavailability of such required data. An attempt has been made to classify attributes into high, medium and low weight categories based upon their significance in finding the SSI. The SSIs have been calculated for two sites of Varanasi, one site of Bangalore and one arbitrarily selected most sensitive site. The analysis of this study indicates that the error may be high (>10%) if more than two data of high weight category are not available, whereas a marginal error (5-10%) is incurred if up to 10 parameters having low or middle weights are not available. A software program has been developed in Visual Basic to calculate SSI based on available data and guide the user about the importance of the missing attributes.

In the recent updates being done in our editorial board we are receiving many volunteer applications from learned persons across the globe to become our editors. As and when a decision is made we are updating our editorial board, recent addition to our elite panel of editorial board is Prof. Lim Hwee San from Malaysia had joined as Executive Editor of the journal.
Lim Hwee San, have been a lecturer in Universiti Sains Malaysia (USM) after obtaining a PhD degree from USM in 2006. He obtained my B.Sc. from USM in Geophysics in 2001. After receiving my B.Sc. (Hons), He continued my M.Sc. and PhD under the supervisions of Assoc. Prof. Dr. Mohd. Zubir Mat Jafri and Assoc. Prof. Dr. Khiruddin Abdullah. Finally, He obtained my M.Sc. degree and PhD degree from USM in environmental remote sensing in 2003 and 2006 respectively. His research interests lie generally in the field of optical remote sensing – both passive and active – and digital image processing, particularly as it applies to spectral image data. In both cases, the primary applications are water quality monitoring, air quality monitoring, land cover/change detection, land surface properties and digital images classification. Hs is also interested in modeling of the optical properties of atmospheric aerosols. His current effort focus on the application of satellite based LIDAR (e.g., CALIPSO, AIRS) data for air pollution and green house effects study. He had published more than 320 articles in these areas and also published 5 chapters of book and 4 monographs. He also published 18 articles in the national and international journals and another two is being reviewed. He is a member of International Society for Optical Engineering US. In the research area, He and his research team have been awarded a Bronze Medal at The International Invention Innovation Industrial Design & Technology Exhibition 2003 (ITEX03) for the invention of Environmental Predator. He and his research team were also awarded a Silver Medal in an Expo Science, Technology & Innovation 2004 (EXPO S&T 2003, MOSTE) for the invention of Real–Time Environmental Sensing. In Expo Science, Technology & Innovation 2004 (EXPO S&T 2004, MOSTI), I and my research team were awarded with Silver Medal for the invention of Multispectral Water Quality Sensor and Bronze Medal for the invention of Real–Time Air Pollution Measurement System. In 2006, the invention of Intelligent Air Pollution Measurements System developed by me and my research team won three awards which is The International Invention Innovation Industrial Design & Technology Exhibition 2006 (ITEX06) with Gold Medal, Special Award of Best Invention of World Intellectual Property Organisation Award (WIPO) and Special Award of Best Invention of Kandiah & Associate Award (KASS). He and his research team were also awarded a Silver Medal in Invention & Innovation Competition 2007, Malaysia Technology Expo 2007 (MTE 2007) for the invention of Multispectral Cell Freshness Detection System. In year 2007, I and my research team were also awarded a Silver Medal in International Exposition of Research and Inventions of Institutions of Higher Learning 2007 (PECIPTA 07) for the invention of FireBuster – A Novel Automatic Fire Detection System. I and my research team were also awarded a Silver Medal in Pameran Eureka 2007, 56th World Exhibition Of Innovation, Research & New Technologies Brussels, Belgium for the invention of AirWarn: Intelligent Air Pollution Measurements System. Currently, He is the Principal Inverstigator (PI) under the 2nd Research Agreement for the Advanced Land Observation Satellite (ALOS) between the Japan Aerospace Exploration Agency (JAXA), Japan and the Research Organization (Universiti Sains Malaysia – USM) since 2007. Besieds, he is also the Principal Inverstigator (PI) under the Announcement of Opportunity (AO) for the Thailand Earth Observation System (THEOS) between the Geo-Informatics and Space Technology Development Agency (Public Organization), Ministry of Science and Technology, Thailand and the Research Organization (Universiti Sains Malaysia – USM) since 2009 and the Principal Inverstigator (PI) under the Announcement of Opportunity (AO) for the OCEANSAT-2 between Indian Space Research Organization (ISRO), India and the Research Organization (Universiti Sains Malaysia – USM) since 2009. He is particularly intrigued by the use of ALOS data and remote sensing to integrate the understanding of the environmental changes in Malaysia. He is a member of The International Society for Optical Engineering (SPIE) USA and International Society for Potogrammetry and Remote Sensing (ISPRS).
On behalf of Integrated Publishing Association we extend warm welcome to Prof. Lim Hwee San, we hope with his inclusion the journal will take a giant leap towards achievement.
