For any urban pollution management, authorities, specialists, and the public play a major role. To promote and sustain quality of life, interaction between these, which is dynamic in nature, is very crucial. A balance between economy, society, environment and technology is required. Currently considerable amount of environment related data is available in dispersed manner such as fuel technology, emission inventory, industrial data, control measures, town planning and transport, health impact study, geographical data (land use, land cover), population, meteorology and air quality measurement data, pollution control board reports, ecology impact. With advent of computer technology, Internet, automatic monitoring network and GIS, integration of this inter-linked data is a necessity for correct and timely decisions for pollution control.
Objective of this computer based system is to provide useful science based information derived from various environmental components to improve urban air quality and to assist in operational decision-making. Main constituents of an air quality management system are updated emission inventory, air pollution monitoring data, dispersion / air quality modeling (statistical / numerical), risk assessment factor, pollution exposure data, control strategies, cost-benefit analysis, scenario prediction, dissemination and distribution of environmental related data using internet, quality control information, human interface with the integrated system to extract and analysis information for policy decisions, research and action plans. This integrated system will support cause and effect analysis and as well as cost-benefit analysis. It will give access to advanced tools of data analysis and design and evaluation for assessment and control of urban air pollution with easy interface for any user. The primary components of the system are (i) Integrated database management, (ii) Query system for decisions on strategic analysis, optimization, scenario selection, statistics, impact assessment with user-friendly graphical interface, (iii) GIS for information dissemination over the Internet useful for citizens and policy makers, and (iv) Report generation facility. Thus providing timely, accurate, understandable, usable and easily obtainable information for clean air initiatives of Indian cities.
