National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow We conducted two studies first shifting channels of the Gomti river with the help of satellite data IRS 1-D PAN LISS III and second regarding presences of heavy metal contamination in the water of Gomti river. Thus water management has emerged as the need of the hour. Revival of water bodies and judicious use of water resources is the only way to ensure its availability in the due course of time. Therefore, under water management , we will unfold past, present situation of the dying ‘Life-Line’ of the city and solutions that will encourage groundwater recharging in the potential zones in-order to restore and rejuvenate one of the most precious gift bestowed by God on the city of Nawabs ‘Gomti river’. EVALUATION OF RISK OF LAND VULNERABILITY ASSESSMENT THROUGH EDAPHIC CHARACTERISTICS: USING GEO-SPATIAL APPROACH Azizur Rahman Siddiqui Department of Geography, University of Allahabad, Allahabad-211002, (U.P) email: aziz_rs1970@yahoo.co.in Land vulnerability involves long term changes in the floral and faunal characteristics, its soil productivity and its biological production potentials. The soil of an arid environment varies in their nature and composition. Generally, soils of these areas developed under the condition of high thermal regime and stress of moisture supply. These are prone to severe wind erosion unless properly protected by vegetation cover. The physical properties of soil depend on amount, nature, size, shape, arrangement and mineral composition of its particles, organic matter and content. The physical properties of a soil greatly influence its use and behaviour towards sustenance of plant life. Now remote sensing application and G.I.S technique has become subject of prime interest for soil scientist to detect inherent spectral behaviour of heterogeneous characteristics of soils. The main aim of this research paper to examine how edaphic characteristics derived from remote sensing are useful in characterization of vulnerability to land degradation in Churu district of Western Rajasthan. 52
National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow COMPARATIVE ASSESSMENT OF AMBIENT AIR QUALITY IN SELECTED SITES OF VARANASI Shailendra Tripathi 1 , Ankita Singh 2 , Ankita Chaurasia 2 , Mamta Yadav 2 and Shusheel Kumar Singh 2 1 Sampoornanand Sanskrit University, Varanasi 2 Microtek College of Management & Technology, Varanasi Air quality data (SPM, NOx and SO 2 ) of five sites (Godaulia, Sigra, B.H.U., Pandeypur and Cant Railway Station) of Varanasi was analyzed and compared to evaluate: (1) the exceedances of air quality against CPCB air quality limits, (2) primary air pollution sources and their contribution to the ambient load and (3) monthly patterns of air pollutants. High SPM levels, close to the thresholds for human health and clearly above the threshold for the protection of plants and ecosystems, were observed in Godaulia and Pandeypur. SPM and NOx level in Sigra was significantly higher than the limits for human health and plant’s protection. The values of all SPM, NOx and SO 2 were higher in Cant railway station than other three sites, whereas all the values of SPM, NOx and SO 2 were lower than the CPCB limit at B.H.U.. The high traffic in these areas may drive the diurnal pattern of SO 2 , NO x and SPM in the city. Our results support the hypothesis that the high concentration of SPM is due to the construction activity and the excessive movement of pedestrians in the studied areas and this has reduced in such areas. However the higher value of SO 2 and NOx emission is due to vehicular traffic congestion. Based on the comparison of all the five sites of Varanasi, we suggest the occurrence of a feedback mechanism between green belt ecosystem (B.H.U.) and the polluting anthropogenic ones (selected study sites). PARTICULATE MATTER AND ASSOCIATED METALS LEVELS IN AMBIENT AIR AROUND A COAL BASED THERMAL POWER PLANT Kunwar Anand Singh, Vidhu Gupta, Vipin Shukla, Puspanjali Dubey and SC Barman Environmental Monitoring Division, Indian Institute of Toxicology Research, M. G. Marg, Lucknow- 226001 Particulate Matter (PM), an ambient air criteria pollutant, is a complex mixture of chemical components. Nowadays, the level of PM in ambient air is a major concern 53
