National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow STUDY OF SPATIAL VARIABILITY OF GROUND WATER DEPTH AND QUALITY PARAMETERS IN HARIDWAR DISTRICT OF UTTARAKHAND Pradipika Verma Indian Institute of Remote Sensing, 4 Kalidas Road, Dehradun 248 001 Ground water is a key source of drinking water that is essential to life on Earth. Assessing the quality of groundwater is important to ensure sustainable safe use of these resources. Geostatistical methods have been used widely as a convenient tool for assessing groundwater depth and ground water quality parameters. The objective of the study is to determine the groundwater quality and to assess the risk of groundwater pollution in Haridwar district of Uttarakhand, India by using geostatistic techniques. The groundwater quality parameters were analyzed from the existing wells of the Haridwar district and the thematic maps were generated using geostatistical concepts. Ordinary kriging was used to analyze the spatial variability of groundwater depth and quality parameters such as electrical conductivity (EC), bicarbonate, calcium, chloride, magnesium, sodium, potassium and sulphate with concentrations equal or greater than their respective groundwater pollution cutoff value, whereas indicator kriging was used to analyze groundwater quality parameters equal to or greater than the pollution threshold values. It was observed that the semi-variogram parameters fitted well in the gaussian for water depth and in the spherical model for water quality parameters. (EC followed a log-normal distribution and demonstrated a moderate spatial dependence according to the nugget ratio) (Cross-validation errors are within an acceptable level). The indicator kriging method is useful to assess the risk of groundwater pollution by giving the conditional probability of concentrations of different chemical parameters exceeding their cutoff values. Thus, risk assessment of groundwater pollution is useful for proper management of groundwater resources and minimizing the pollution threat. 116
National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow ECO-FRIENDLY LIVELIHOOD GENERATION AND WASTE MANAGEMENT Ravindra Kaur School of Environmental Sciences, New Delhi. email:ravindrakaur@yahoo.co.in Livelihood is a primary tool for the holistic development of any society. The present research paper signifies the need of generation of sustained livelihood means for women of underprivileged strata dwelling in urban slums. Ecofriendly livelihood helps in developing environmental awareness, capacity building, sensitivity to social issues and healthy life-style. In the present scenario of "Global Climate Change" mankind is forced to adopt the ecofriendly approach for sustainable development. Present concern of ecofriendly livelihood for poor women is a vital element especially for mothers and would be mother work force. In this study household products such as kitchen mops, wash-basin/ tiles scrubbers, doormats, dry-fruit containers, car accessories etc were made from various raw materials such as post consumer paper waste, coconut shells, vegetative (leaf, stem), corn leaves, wheat straw, bagasse etc. In the process of manufacturing the consulate oriented value addition was carried out in a natural and ecofriendly manner to achieve aesthetic value, optimum waste utilization and to make user friendly products. The flowers, aromatic oils, chandan powder, vegetative colors and natural fragrance were used instead of synthetic and environmentally harsh components. Hence the complete process to make value added products can be categorized as Green Process which also generate money along with waste reduction and causing least burden on the climate. 117
