1. Environmental Impact Assessment (EIA) is an important management tool for ensuring optimal use of natural resources for sustainable development. A beginning in this direction was made in our country with the impact assessment of river valley projects in 1978‐79 and the scope has subsequently been enhanced to cover other developmental sectors such as industries thermal power projects mining schemes etc. To facilitate collection of environmental data and preparation of management plans guidelines have been evolved and circulated to the concerned Central and State Government Departments. EIA has now been made mandatory under the Environmental (Protection Act 1986) for 29 categories of developmental activities involving investments of Rs. 50 crores and above.
2. With the greater need for accessing data for conducting an EIA or any kind of environmental assessment availability of data in a ready and interactive format is the basic requirement. IL&FS first conceived the concept of evolving a knowledge database for this purpose. The concept of “Environmental Information Centre” (EIC) was strategized and developed in 2002 by IL&FS in partnership with the Ministry of Environment & Forests.
3. In information theory systems are modeled by a transmitter channel and receiver. The transmitter produces messages that are sent through the channel. The channel modifies the message in some way. The receiver attempts to infer which message was sent. In this context entropy (more specifically Shannon entropy) is the expected value (average) of the information contained in each message. 'Messages' can be modeled by any flow of information.
