In the recent past, the dependency of Indian agriculture on ground water resources has increased upto an enormous extent due to several factors including increased demand of food, erratic behavior of monsoon, developmental pressure of various allied sectors etc. Currently, the available 70% of water resources in India being used to fulfill the water demand for agriculture and the 80% of domestic water supplies come from groundwater which led to rapidly declining groundwater tables in most of the states in India and has found no longer sustainable. Present study has primarily highlights the need of the Indian conditions for treatment and reuse of wastewater which happens to be the main cause for pollution of water resources in India. In this study efforts were made for assessment the potential of model sewage fed aquaculture system of capacity 8 MLD in Karnal, India for wastewater treatment, reuse and resource recovery during the treatment process. The in-depth evaluation study were conducted for integrated assessment of STP in association with health, environment, society, and institutions aspects as well as quality of treated effluent subjected for reuse in irrigation. The Economic analysis of the model sewage-fed aquaculture system shows that there was an annual profit of INR 8-10 lakhs through selling of fish in local market as well as ample amount of revenue generated through selling of treated effluent to the farmers. Also, the irrigation with treated wastewater able to save the fertilizer upto 50kg of Urea and 50kg of diammonium phosphate during cultivation of one acre of crop annually. The system was found good for removal of physic-chemical pollutants and also found very effective in removal of bacteriological pollutants. The reported removals for total coliform, fecal coliform and fecal streptococci were found 99.988, 99.965 and 99.9567, respectively.

India is the world's leading ship recycling country which works on the principle of
Dismantling and recycling of end-of-life vessels in the so-called environmentally friendly manner... more Dismantling and recycling of end-of-life vessels in the so-called environmentally friendly manner has been a major challenge faced by ship owners, ship dismantling yard owners as well as government agencies worldwide today. On one-hand, this paper intends to provide the knowledge-base needed by individual yard owners for planning their short term and long term activities. On the other hand it is hoped that this paper will serve as an essential part of the management information system which will help in governance of cluster of ship dismantling yards. The emission factors estimated in this study using field sample survey of 241 ships dismantled during 2011e2013 in the cluster at Alang Port could be put to use while predicting the quantities of wastes generated from dismantling of six types of ships (bulk carrier, general cargo, container, refrigerator and passenger) which further can be used in preparing environmental management plan to handle the same. The % ships and % cumulative LDT of ships in a given category could also be predicted for the cluster using the validated results reported in this study. Finally, on the basis of primary data collected from over 100 yards in Alang Port and with the help of face-to-face interactions with several field personnel; a "typical ship dismantling and recycling procedure" was articulated.
