Natural disaster as wild-land fires, floods, earthquakes and volcanic eruption usually result in significant environmental degradation, economic and human losses. To minimize the consequence of these catastrophic events, fire managers and national authorities need accurate information regarding the geographic extents, the affected area, both during the outbreak and shortly after then suppression of the events. The historic fire record data is also of great importance for the planning and decision-making process. They pose a threat not only to the forest wealth but also to the entire regime to fauna and flora seriously disturbing the bio-diversity and the ecology and environment of a region. During summer, when there is no rain for months, the forests become littered with dry senescent leaves and twinges, which could burst into flames ignited by the slightest, speak.

Active fire points of MODIS, VIIRS, INSAT 3D and INSAT 3DR were used in this study. In this study we characterize each fire points with admin boundary, LU/LC, Elevation, Aspect, Slope, Vegetation type, Forest density, Heterogeneity, Biomass, Phenology and weather data. So, we came to know that which type of biological, physical and ecological parameter are more prone to fire. This study makes us one inch closer to fire safety and management system, which is useful for maintaining our ecosystem.

The project investigates the concentration of the pollutants Sulphur dioxide, Nitrogen oxides, respirable Suspended Particulate Matter and Suspended Particulate Matter generated from various sources like Automobiles, Industries over the ambient air quality of the sector-30, Gandhinagar, As such Gandhinagar is a big city and it is not possible to measure the concentration of these major pollutants as suggested by the Gujarat Pollution Control Board in an industrial area are Sulphur Oxide, Nitrogen Oxide, Particulate Matter (PM10) and Suspended

Particulate Matter. The rate of emission and concentration of these gases in ambient air is studied by the following laboratory method- (a) Modified west and Geake method for determination of Sulphur Oxide in ambient air (b) Modified Jacob and Hochheiser method for determination of Nitrogen oxide (c) High Volume Method for determination of Suspended Particulate Matter in ambient air (d) Gravimetric method for the Measurement PM10.The Results will show the

concentration of emission of the above cited gaseous and suspended solid pollutants and will be compared with the permissible concentration as per the standard given by CPCB for Residential area and major precaution can be taken to reduce the concentration level of these pollutants. 28.

Remote sensing and Geographical information system (GIS) have been used to study the change in land use and land cover of Taranga hill forest with respect to understand the wildlife habitats.

ERDAS IMAGINE software and Maximum Likelihood Algorithm (MLA) supported by the field observations. The results obtained shows significant change in land use in the major classes like dense forest, open forest and barren land. Water body, dense forest and open forest was decreased; whereas agriculture, settlement and barren land increased in the last ten years. The wildlife habitat and threats on it was assessed using proximity analysis and Normalized differencing vegetation index (NDVI) classification, which reveals that the remaining forest areas of Taranga may have a serious threat from urbanization, agricultural expansion and transport. The study also recommends for a long term exploration of habitat use by wildlife, threat analysis and biotic pressure on the forest on a seasonal basis so that long term management and conservation strategies can be formulated for this small but very important wildlife habitat. 29.

This study was conducted to evaluate the river water quality of Tapi. Samples collected from five different. The sample were analyzed for physical and chemical parameters such as pH, temperature, EC, TDS, TSS, Total Acidity, Total Alkalinity, Sulphate, Chloride, Total Hardness, Calcium, Magnesium, COD, BOD, by using standard water testing methodology. The determinate water quality parameter was compared with standard value provided by the Bureau of Indian Standard (BIS) in order to evaluate the river quality.

The study reveals that many water quality parameters beyond the permissible limit of the BIS at all sites. These all sites ate industrial areas which almost all the parameters beyond to permissible values suggested by BIS. Temperature, pH, EC, BOD and COD are within the permissible value in each of the five sites while sulphate, chloride, acidity, alkalinity, magnesium, calcium hardness was exceeding the permissible value in all the sites.

Overall the study shows that the river side which is the most exploited by human activity as poor water quality and the aquatic life in such locations is under the threat. Proper waste disposal regulation pilgrim activity close to river awareness of local villages can be very important to sustain the quality of river and conservation of the fresh water biota of the river Tapi.

30. Study on deteriorating effects of microorganisms on ancient monuments by microbes

The microbial deterioration of stone monument is major issue in worldwide for their future existence. Deteriorating effects of microorganisms on ancient monuments of Patan, Gujrat studied by taking various samples from deteriorated parts of the monuments with non-destructive sampling methods such as sterile adhesive tape and cotton swab. In isolation 25 isolates were isolated on selective media in which after screening 7 positive isolates (5 bacterial+ 2 fungus) obtained. Microorganisms deteriorate the monuments by various effects such as corrosion, discoloration, biofilm production etc. On the basis of effects urea agar medium was chosen for screening method. Positive isolates were identified on the basis of colony morphology, Gram’s Staining, Mounting of molds and biochemical tests. For the bioassay select the higher pink color forming bacterial isolates. Bioassay of urease enzyme activity performed for 4 isolates (2 bacterial+ 2 fungus) and estimate presence of ammonia. In bioassay which has higher ammonia production bacterial strain is Moraxellabovis which is lower ammonia production strain comparatively to fungus and higher ammonia production compared to Proteus. Aspergillus has high ability to utilize urea and also urease enzyme activity. Fungi showed higher capability of utilization of urea and production of ammonia compared to bacteria. Fungus showing higher ability to deteriorate ancient monuments compared to bacteria.

An increased use of metals and chemical nutrients in the industrial process has resulted in the generation of large quantities of aqueous effluents, there by creating serious environmental disposal problems (Antunes et al., 2003, Appel and Ma, 2002). Heavy metals, mostly from domestic, agricultural and industrial activities which are not biodegradable (Vijayaraghavan et al., 2004) are therefore of great concern and existing technologies for heavy metals’ removal from waters and wastewaters are often ineffective (especially at environmental levels), expensive and unavailable in developing countries. There is need to find alternative inexpensive and effective methods for nutrients and heavy metals abatement from wastewaters becomes inevitable. Bio sorption is an emerging field in this regard and has great potentials, involve in use of living or non-living biological materials for pollutant removal from aqueous solutions and industrial effluents. Biochar is pyrogenic black carbon-rich biomass in an environment. Moreover, Biochar used as a low-cost bio adsorbent to heavy metal and nutrients removal from wastewaters is promising and an emerging wastewater treatment technology. Adsorption on the other hand, mostly important processes used to remove heavy metals from aqueous solutions and wastewater mainly due to its large surface area, distributed pore size, distributed particle size and highly surface reactivity. Therefore in the present investigation an attempt has been made on “removal of nutrient and heavy metals from industrial effluents using orange (Citrus sinensis) peeling waste as Biochar: an alternative for environmental pollution mitigation”. In current study utilization of Orange (Citrus sinensis) peeling waste as Biocharis prepared and acts as a adsorbent, characterized for size by SEM, functional group variation by FT-IR, elemental composition by EDAX, optimization at different contact time, PH, agitation and amount of adsorbent and eventually removed nutrients likePO4-, SO4-,NO3-, Chloride and heavy metals-

Iron and Chromium from the industrial wastewaters- Textile, Dye industrial effluents, pharmaceutical wastewater ranging from 30 to 95 percent removal.
