Abstract The Ministry of Environment and forest government of India issued the Environmental Impact Assessment notification, 2006.The basic objectives of Environmental Impact Assessment is to identify, predict, mitigate the possible impact due to proposed project and the people likely to be affected. The project of Environmental Impact Assessment (EIA) leads to mitigate the negative impacts and enhance the positive impacts for the Sustainable developments. In the present study Indian Remote Sensing Satellite (IRS) data from the 2006 to 2012 were used to generate Land-use, water-bodies, transport network and waste-land maps of the Amreli and Junagarh districts. The various criteria defined by Environmental Impact Assessment were used for identifying sites for industries based on the guidelines of Environmental clearance. A Decision Support System (DSS) based on VB.NET programming were implemented for identifying sites for industries and environmental clearance in Amreli and Junagarh districts. This decision Support system uses the various criteria for locating sites for industries and Environmental Clearance in Amreli and Junagarh districts.

1. INTRODUCTION

   The Environment Clearance strategy, plan should be produced with the Proper arrangement and acquiring knowledge of our surroundings resources such as Roads, Railways, Settlements, Buildings etc without harm to our nature. It is very necessary to use suitable criteria for planning and locating suitable location of industries. In this paper all the Criteria are taken from the Gujarat Pollution Control Board (GPCB) and Central Pollution Control Board (CPCB). These Criteria are helpful for managing environment to our Surroundings. Remote Sensing and GIS data is used to generate land use. In this paper firstly the waste-land is identified and then the necessary criteria is fulfilled after interpreting map, the waste-land portion is calculated. The appropriate balance between environment and human society should be maintained, in other words, the sustainable development or programme should be holistic and avoid being

   single-sector (for example: coastal erosion, water, nature conservation, spatial planning, etc).

2. OBJECTIVES

   The objectives of this study for Environmental Clearance in Junagarh & Amreli districts are as follows:

   • Study of Waste-lands in Amreli and Junagarh Districts

   • Identification of Criteria where the industries to be established

   • Establish Industries with Sufficient Criteria.

   • Ensure preservation of the integrity of coastal ecosystems, landscapes geomorphology

   • Prevent and reduce the effect of natural hazards & in particular period which can be induced by natural or human activities.

   • Proper use of land by establishment of Settlement, Agriculture, Roads, Railways etc.

3. ENVIRONMENTAL CLEARANCE

   1. Environment Impact Assessment (EIA)

      The purpose of Environmental Impact Assessment (EIA) is to identify and evaluate the potential impacts (beneficial and adverse) of development and projects on the environmental system. It is an useful aid for decision making based on understanding of the environment implications including social, cultural and aesthetic concerns which could be integrated with the analysis of the project costs and benefits. This exercise should be undertaken early enough in the planning stage of projects for selection of environmentally compatible sites, process technologies and such other environmental safeguards.

   2. Environmental Criteria for Industries

      In order to help the concerned authorities and the entrepreneurs, it is necessary to frame certain broad guidelines for citing an industry. It is also necessary to identify the parameters that should be taken into account while setting up

      an industry. With this in view, the following environmental guidelines are recommended for citing of Industries to ensure optimum use of natural and man-made resources in sustainable manner with minimal depletion, degradation and/or destruction of environment. Those are in addition to those directives that are already in existence under the Industries (Development and Regulation) Act. In citing industries, care should be taken to minimize the adverse impact of the industries on the immediate neighbourhood as well as distant places. Some of the natural life sustaining systems and some specific land uses are sensitive to industrial impacts because of the nature and extent of fragility.

   3. Industrial Criteria to Sustain Ecological System

   It is necessary to fulfil criteria for the set up of new industries. As for example, industries should be at least 25km away from Ecological System. Coastal areas: at least 1/2 km from High Tide Line. Flood Plain of the Riverine Systems: at least 1/2 km from flood plain or modified flood plain affected by dam in the upstream flood control systems. Transport/Communication System at population): at least 1/2 km from highway and railway. Major settlements (3,00,000 distance from settlements is difficult to maintain because of urban sprawl). At the time of citing of the industry if any major settlement's notified limit is within 50 km and the industry shall be cited at least 25 km from the projected growth boundary of the settlement.

4. STUDY AREA The Amreli and Junagarh Districts are situated

   between 26.6200N Latitude, 71.2300E Longitude and, 21.5200N Latitude, 70.4700E Longitude in Gujarat. They Comprises the West portion of India which is shows in figure 1.

5. METHODOLOGY

   1. Data Used

      Following Indian Remote Sensing Sateliite Data covering Junagarh and Amreli Districts was used for Data analysis shown in table1.

      S.no.	Satellite	Sensor	Path/Ro w	Date of pass
      1.	IRS P6	LISS-III	92/57	4 Jan2012
      2.	IRS P6	LISS-III	97/57	11 Jan2012

      Table 1 : IRS Path/Row Date

   2. GIS Data

      1. Disricts Boundary, Taluka, Village Boundary.

      2. Transport Network like National Highways and Railways.

      3. Major Water Bodies Like Streams, Rivers, Ponds and Village Tanks.

      4. Forest and Settlements Locations.

   3. Satellite Data Analysis

      In this study, Indian Remote Sensing Satellite (IRS P-6) LISS- III data is used. The IRS P-6 digital data was geo-referenced and the mosaics were created in ENVI 4.0, the study area. The resolution of LISS-III is 23 meter which helps to identify the arious land use classes very clearly. Figure-2 shows the mosaic image covering two district boundry i.e. Junagarh and Amreli Districts.

   4. Geo-Spatial Data

   Various GIS layers like Transport Network, Water Bodies, Taluka Boundry and village Boundary superimposed to satellite data. This is very useful to know information about the village .At which year the taluka & Village is Established. At how much the Area of Village is covered .By Geo-Spatial Data we know about the certain nformation how many taluka

   is present and what their are names and which districts they belongs.
