National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow and westerly phase of Quasi Biennial Oscillation (QBO) at 50- hpa level. The 30-year sliding correlation coefficient also has been made to know the PNA parameter is efficient predictor of Indian summer monsoon rainfall in present condition. In both cases DJFMAM, FMA, MAM and April shows the significant association with Indian summer monsoon rainfall and association of these parameter is also changed according with QBO phase. RAINWATER HARVESTING MODELING FOR SUSTAINABLE DEVELOPMENT OF GROUND WATER RESOURCE IN LUCKNOW DISTRICT, UTTAR PRADESH Madhu Rai 1 , Anju Verma 2 , Archana Gupta 3 , Kamlesh Kumar 4 , Biswajeet Thakur 4 , Akanksha Shukla 3 and Droupti Yadav 1 1 Department of Geology, Lucknow University, Lucknow 2 Department of Environmental sciences, IBSBT, CSJM University, Kanpur 3 Department of Geography, Lucknow University, Lucknow 4 Birbal Sahni Institute of Palaeobotany, 53, University Road, Lucknow Water, the most essential component in the living environment, though widely distributed but only limited volume can be used for drinking and domestic purposes. Global factor on water corresponds to the fact that very limited water can be utilized for household activities and within that also much of the stored water is in the form of groundwater. In a densely populated and agriculture based country like India, ground water resource has significant role. The agricultural sector totally depends upon the monsoon and if the rainfall is not adequate then ground water is used exhaustibly to meet the demands. In many places of the world including India, this indispensable resource is under stress due to continuous failure of monsoon, increasing urbanization, acquisition of natural water bodies, excessive extraction and the excess use of ground water and ultimately leading the country to a stage of ‘hydrological poverty’ resulting in environmental degradation. In the present study an attempt has been made to use rainwater harvesting (RWH) model in the Lucknow region so that the excess rain water that is wasted in the form of runoff can be stored and managed sustainably for local use as well as ground water recharge. This RWH model is based on remote sensing (RS) and geographical information system (GIS) techniques by utilization of land use sector. Lucknow, the capital of the most populated state (Uttar Pradesh) of the country, has shown a quantum jump in population growth and expansion in its urban sector. The continuous increase of the population in the last 3 decades has put tremendous pressure on the existing civic services including supply of water. The present demand for water in Lucknow is around 791.51 MLD whereas the supply from all the available sources is 108
National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow about 515.87 MLD. The financial, administrative and technical deficiencies of the supply system have led to the deterioration of the water supply in the city. The demand of water has considerably increased due to the improvement in standard of living vis-àvis growth. The increasing pressure on the ground water resources, has led to an alarming situation. Though, the rate of declining of ground water is different in different localities, however, the average is 0.82 m per year for the entire city. In the present RWH model, the RS and GIS methodology has been successfully incorporated to visualize the suitability of different classes for best use of rain water. In total, nine zones have been indentified for land utilization purpose. These are based on the suitability index according to their use in agriculture, water body and settlement mask with least proportion designated as poor or very poor class. The zones 1 to 7 represent excellent to satisfactory in RWH model this indicate that these sectors have to be primarily used for the rain water harvesting practices. This includes the agricultural land with settlement masks and natural water bodies. The 8 and 9 th class designated as poor and very poor zones are salt affected or wasteland. The present RWH model can be used for utilization of rainwater for recharging ground water. In addition it is sustainability that counts in the end and the present model has been stipulated for the betterment of land use of the given area in future. ALTERNATIVE TO MINING AND METALLURGY C.D. Dwivedi DRDO MUD GOI, DMSRDE, Kanpur email: dwivedi.chandradhar@rediffmail.com The day is not for of when we will have to look for an alternative to our mother earth for our survival. The pace with which we are draining our resources the day is not for of when certain of our most valuable natural resources such as ores, minerals will disappear. So sooner the better we realize and start conserving, preserving and ensure optimal utilization so as to avoid the wastage. At the same time we should start looking for possible synthetic route for our valuable ores in the laboratory which will be helpful in controlling environmental degradation due to mining and excavation. We have ventured to synthesize in the laboratory minerals of the alunite series in the laboratory. Alunite has potential value as a source of both aluminium and potassium compounds. Alunite and related jarosites are of the mineralogical interest on account of many types of isomorphous replacements shown by them. A clearer understanding of the structure of these minerals may pave the way in aiding mineralogist and geologist in study of the genetic significance of the aluminium hydroxide minerals and possible of related clay minerals. Lattice parameters and densities of the synthesized minerals as well as 109
