National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow increasing soil organic carbon through restoration of degraded soils and widespread adoption of soil conservation practices. The Intergovernmental Panel on Climate Change identified creation and strengthening of carbon sinks in the soil as a clear option for increasing removal of CO 2 from the atmosphere and has recognized soil organic carbon pool as one of the five major carbon pools for the Land Use, Land Use Change in Forestry sector. Land is being used for different purposes viz. for forestry, agriculture, agroforestry, pastures, horticulture, plantations, habitat etc. Land use and soil management practices can significantly influence soil organic carbon. Accurate quantification of soil carbon is necessary for detection and prediction of changes in response to changing global climate. Enhanced sequestration of atmospheric CO2 in the soil, ultimately as stable soil organic matter, provides a more lasting solution than sequestering CO2 in standing biomass. SUSTAINABLE DEVELOPMENT BY PERENNIAL WATER SUPPLY IN UTTARAKHAND Abhishek Kumar and K.S. Misra Department of Petroleum Engineering and Earth Sciences, University of Petroleum and Energy Studies, Dehradun Uttarakhand is bestowed with a high potential of water resources. It receives water from monsoon rain as well as from westerly disturbances. These westerly Disturbances are also the main source of snow fall in upper regions and rainfall at lower elevations. Geomorphology and geology of Uttarakhand favours storage of enormous amount of rain water which can be utilized for generation of electricity and for continuous and regulated flow of water through integrated natural drainage system. The present study is based on interpretation of different satellite data sets. The imagery from Indian Remote Sensing Satellite (IRS) is utilized for gathering geological and geomorphological information. Satellite RADAR data is found to be exceptionally useful for studies related to snow, ice, glaciers and permanent as well as temporary water bodies. Radar data has helped in mapping of certain geomorphological features related to surface roughness and moisture content in different units. The study also formulates technique which can be applied for, not only assessment of water resources but also proper utilization for development and revenue generation for the state. This will flooding in Ganga and Yamuna basins in adjacent states. 112
National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow RECYCLING OF AGRICULTURAL SOLID WASTES FOR THE REMOVAL OF ORGANIC AND INORGANIC POLLUTANTS FROM WASTE WATERS BY ADSORPTION PROCESS Chinnaiya Namasivayam Faculty of Science & Chairman, Department of Environmental Sciences, Bharathiar University, Coimbatore 641 046 email: cnamasivayam@yahoo.com Industrial growth and associated technical sophistication in the last three decades or so has posed major problems of solid waste disposal. It has become essential either to find suitable ways for the safe disposal of the wastes or to suggest novel uses, considering them as by-products. Otherwise these will remain an accumulated waste, contributing highly to environmental pollution. The choice between recovery of valuable materials from waste and disposal of waste depends mainly on three factors: technology, economics and attitude. In developing countries like India, industries cannot afford to use conventional wastewater treatment chemicals like alum, ferric chloride, polymer flocculants and coal based activated carbon because they are not cost-effective. Among the treatment methods adsorption seems to be an effective method. An inexpensive and more easily available adsorbent would make the removal of pollutants an economically viable alternative. Agricultural wastes like orange peel, banana pith, coir pith, peanut hull etc. are discarded in the agricultural sector. These wastes contain cellulose and lignin, which act as very good adsorbents. Namasivayam and coworkers have investigated to recycle these agricultural solid wastes as adsorbents with and without chemical modification for the treatment of industrial effluents. Physically and chemically activated carbons derived from coir pith, peanut hull and Jatropha husk; and wastes such as biogas residual slurry, banana pith and orange peel were found to be efficient for the removal of dyes, toxic metal ions and anions from industrial wastewaters. Results of batch mode adsorption studies using the above adsorbents and applications to the treatment of real industry effluents will be presented in this lecture. Kinetics and temperature effects of adsorption will be discussed. 113
