National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow SOLID WASTE MANAGEMENT Reshu Yadav Department of Water Resource Development and Management; Indian Institute of Technology Roorkee, Uttarakhand 247667. Waste generation, both domestic and industrial, continues to increase worldwide in tandem with growth in consumption. In developed countries, per capita waste generation increased nearly three-fold over the last two decades reaching a level five to six times higher than that in developing countries with increase in population and living standards, waste generation in developing countries is also increasing rapidly, and may double in volume in the current decade. If current trend continues, the world may see a five-fold increase in waste generation by the year 2025. A high proportion of the waste could be recycled by the urban poor generating income for them-selves protecting the environment. There is need to develop an integrated approach where public, private and community sectors work together to develop local solutions promoting sustainable solid waste management. TEMPORAL VARIABILITY IN ANNUAL PRECIPITATION AND TEMPERATURE SERIES AT NAGALAND, INDIA Pratibha W. and Nayan S. Department of Water Resources Development and Management, IIT Roorkee, Roorkee-247667 email:pratibhawarwade@gmail.com, nayanfwt@gmail.com In the present study an attempt has been made to study the temporal variability of annual precipitation and temperature (minimum and maximum) series at Nagaland, India. Mann Kendall test was used to detect the significance of trends using the period of 1901-2002. Out of seven stations, only two stations showed the significant decreasing trend in precipitation series. Further, no significant trend was detected in precipitation over the entire Nagaland. In temperature series (minimum and maximum) the significant increasing trends was found at all the stations. The maximum temperature shows the greater increase in trend than minimum temperature. Over the entire Nagaland, significant increasing trend was detected in maximum and minimum temperature. Percentage changes over mean values were also calculated. Increases in magnitude greater than 10% were found in temperature and precipitation series at all the stations. 86

H.P. * email: vkparashar53@gmail.com Green chemistry is placed in the frontier areas of research and has been focused for considerable recent research. Green chemistry, the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances is an overarching approach that is applicable to all aspects of chemistry. From feedstock’s to solvents, synthesis and processing green chemistry actively seeks ways to produce materials in a way that is more begin to human health and the environment. The current emphasis on green chemistry reflects a shift away from the historic command and control approach to environmental problems that mandated waste treatment, control and clean up through regulation and towards preventing pollution at its source rather than accepting pollution at its source. Green chemistry seeks new technologies that are cleaner and economically competitive. All synthetic processes involve the use of different solvents which inevitably lead to environmental damage, through pollution, risks to human health and to resource depletion, we need to develop and apply more environmentally friendly approaches. Green chemistry involves design and redesign of chemical synthesis and chemical products to prevent pollution and thereby solve environmental problems. Clearly there will be a continuing need for the definition of novel reaction routes to both multifunctional scaffolds for lead generation and to unique drug like heterocyclic structures microwave irradiation has proved to be a powerful tool for both speeding up chemical optimizations and for efficient preparation of new target compounds. So, all traditional and old synthetic routes are more or less “Grey” in their working and obviously give adverse effects to the mankind and all living beings. Green chemistry provides “Green” paths for different synthetic routes using non-hazardous solvents and environmental friendly chemicals. The fundamentally attractive concept of green chemistry is solvent free reactions. Solvent free reactions can be accelerated by microwave activation and this combined clean technology approach to "greening" chemical reactions. 87
