Abstract: Assessment of, and mapping the extent of forest fragmentation is one of the key requirement for undertaking any eco-restoration work. Using a moving window approach on high-resolution geospatial data on vegetation, a fragmentation index was computed across the entire Indian Landscape. On the basis of the index, the forests areas were categorized as high, moderate, low or intact. It was observed that almost half of the forested land is intact in spite of tremendous population pressures, indicating effective protection. Most of the biodiversity-rich forests, such as evergreen, subtropical broadleaf and temperate broadleaf forests, are relatively intact or have a low degree of fragmentation. But highly fragmented regions across the Indian landscape harbour a number of endemic species, some of them of medicinal importance, that need conservation. This study presents an approach to mapping fragmentation caused by socio-economic drivers, namely shifting cultivation, forest villages, infrastructural development, mining and enroachment. This approach provides critical inputs to prioritization and conservation of forests and the associated biodiversity.

Abstract: Much has been written recently about heedless development policies and the environmental disasters they have resulted in. However, although it is easy in hindsight to recognize that certain environmental decisions were improperly made, in reality environmental decision making is a challenging task. National or region-specific environmental decisions typically affect multiple stakeholders with diverse priorities or objectives. Hence reaching an accord that balances the integrity of the ecosystem with the needs of stakeholders require multidisciplinary knowledge bases that integrate information from the natural, social and medical sciences.

Abstract: With population explosion and increase in pollution have become the necessities of the present day for Optimum use of resources in earth and reduction in waste. The debris from the demolition of building by natural or manmade becomes tedious to disposal the same. The earthquake result in create large amount of building debris. The waste could be reduced by reuse of repaired or old buildings. Rehabilitation and reuse of damaged building result in earthquake could be reducing the pollution due to debris. The GFRP wrapping is one of the rehabilitation methods used widely in field. As the structures become taller, apart from dead load and live loads the structures have to withstand lateral forces. The lateral loads due to wind and earthquake, are a matter of great concern. These require special considerations in the design of all structures. For the selected reinforced concrete structures with the known structural geometry, reinforcement and sizes of structural members, the strength of critical section in beams and columns can be assessed experimentally. In the present study reduced scale model of RCC frame were cast as per IS 456-2000 reinforcement detailing. Once the strength of the critical section is evaluated, the diagnostics of the structures is carried out. The frame was tested under cyclic loading applied by means of actuator and behavior of frame was noted up to failure. Load-Displacement Transducers to register the horizontal displacement, upon the loading the RCC frame under controlled conditions, which include controlled stress and controlled strain conditions. Low frequrncy accelerometrics used to measure the absolute accelerations at critical points. Controlling unit was used to monitor the displacement and vibration parameters. The vibration parameters were plotted against time for each specimen. Based on experimental investigation important conclusion were obtained.

Abstract: Discharge of textile and industrial waste water to surface or ground water is very dangerous. Therefore treatment of any kind of waste water to discharge effluent with good quality is mandatory. Preventing solids deposition is a constant challenge in wastewater treatment. Minimizing particle settlement and subsequent sediment buildup requires strong bulk flow. The Jet Mixing concept was developed in response to problems documented in efficiency of mixing in circular or rectangular tanks Jet mixers in wastewater treatment applications primarily in unit processess where liquid blending, solids suspension, flow generation or chemical reactions are key process parameters. Jet mixers are ideal for these types of applications. The main objective of the present study is to determine the critical velocity of solid suspension by varying the nozzle diameter, nozzle clearance, solid (sand) size and composition. Experimental results show that the fractional hold up increases with increase in jet velocity. The optimum nozzle diameter is found to be nozzle having 10mm diameter, located at 30 cm above the base of the mixing tank. The optimum nozzle design is not universal, and varies with the geometry of system. Correlation for fractional hold up has been developed. Application of jet mixer design for waste water treatment is highlighted.

Abstract: The mudflat snails Telescopium telescopium were collected from 18 geographical sampling sites in the interdial area of Peninsular Malaysia. In this paper, the concentrations of Fe were determined in the seven different soft tissues of the mudflat snails namely foot, cephalic tentacles (CT), mantle, muscle, gill, digestive caecum (DC) and remaining soft tissues(REST). It is found that different concentrations of Fe were found in the different tissues. Based on the hierarchichal cluster analysis of all different soft tissues of T.telescopium, it was found that CT, foot, muscle and mantle are clustered as a single entity while the other major cluster included two subclusters with DC as a single entity while REST and gill as the other one. This clustering pattern is related to Fe concentrations accumulated in each soft tissues of T.telescopium. Present Fe data are important for future reference.

Abstract: The ISO 14001 environmental management standard has been criticized as a public relations fig leaf for polluters. Despite benefits claimed by organisations on ISO 14001 such as improved environmental performance. Corporations that adopt ISO 14001 dont really care about the environment but use it to improve the public image/reputation of the firm without significantly reducing its environmental impacts, the argument goes. This study was to investigate and establish the environmental performance of selected ISO 14001 certified gold mining companies in Ghana as well as to assess the impact of ISO 14001 certification and implementation on environmental performance. The study was based on qualitative and quantitative laboratory analysis of a critical environmental performance indicator in the gold mining industry - surface water and effluent quality. Annual and montly environmental reports of the companies were used in assessing pre and post certification environmental performance. These performance indicators were compared with EPA Ghana Environmental Quality Guidelines to determine the level of compliance with local regulatory standards - a critical and fundamental requirement of the EMS. The results of the study indicate that the implementation of ISO 14001 EMS by two gold mining companies enhanced their environmental performance with regard tp surface and effluent water quality; and it also raised employee awareness of environmental performance with regard to surface and effluent water quality; and it also raised employee awareness of environmental issues. The findings also showed improved complaince with local regulatory water quality guidelines.

Abstract: The concentrations of Cu, Fe and Pb were determined in Nerita lineata snails and sediments collected from Selangor, Negeri Sembilan and Johore between May 2010 and April 2011. This study showed variations of heavy metal accumulations in shells, opercula and soft tissues. The mean concentrations (g/g dry weight) of Cu, Fe and Pb were 5.00, 29.97 and 50.07 for shells; 5.28, 19.50 and 49.34 for opercula; 14.94, 539.25 and 18.83 for soft tissues, respectively. The mean total (?g/g dry weight) concentrations of Cu, Fe and Pb in the surface sediments were 19.72, 25956.14 and 46.99, respectively. Generally the results of this study were comparable with previous reports on the same species. The Pb levels of the snail samples were found to correlate well with the Pb levels in the sediments which confirmed the snail as a good biomonitor for Pb.
