Abstract: Environmental Impact Assessment (EIA) is a process in which environmental factors are integrated into project planning and decision -making so as to achieve ecologically sustainable development. Best-practice EIA identifies environmental risks, lessens conflict by promoting community participation, minimizes adverse enviornmental effects, inform decision makers, and help lay the base for environmentally sound projects. EIA has been identified as an important instrument for facilitating sustainability. However, to do so requires the integration of sustainability into EIA Theory and practice. The sustainability concept is a valid and important Environmental management perspective. Conceptually, EIA and sustainability can be integrated, but frameworks should be refined, adapted to context, and linked to related initiatives. Sustainability should be explicitly incorporated into EIA legislation, guidelines, and institutional arrangements.

Abstract: Fifteen provenances of neem (Azadirachta indica A. Juss) were selected from 12 agroclimatic zones of central India (Madhya Pradesh, Chhattisgarh and Orissa) for the study. Due to various uses of azadirachtin and high variation in oil content, neem trees were selected for assessing higher fruit yield and having having high oil and azadirachtin content in their seeds. The fruit production per tree was assessed by quantifying number of fruits per foot length of branch (NFPF). Significant (P<0.05 - P,0.01) variations were observed on oil, azadirachtin and fatty acids content in the neem seeds collected from different provenances. Oil content ranged from 31.80% (Gwalior) to 47.01% (Katni) and azadirachtin content varied from 848 ppm (Sambalpur) to 5263 ppm (Shahdol). The best zone with respect to high azadirachtin content was found to be the provenances from Shahdol and Sehore, followed by Khandwe , Bargi and Chhindwara. The relative values of different provenances on combined basis depicted superiority of Shahdol provenance over others.

Abstract: Arsenic contamination in groundwater has been envisaged as a global environmental problem. The presence of arsenic in groundwater is controlled by some complex geochemical phenomena. Health hazard due to arsenic contamination has raised the serious concern for public. Here investigation was conducted in thirteen villages of Ghatugachi grampanchayat uner the block Chakdaha of district Nadia, West Bengal, India during 2005-2006. The aim of this study is to provide an overview of the problems regarding the widespread occurrences of arsenic in groundwater in this region. The study revealed that arsenic concentrations in the groundwater ranging from <3.0 to 231.0 ? g/l and in drinking wate it varies considerably among the different locations in this grampanchayat area. Concentration of arsenic in water in the Belgaria ranged from 82.0 to 231.0 ? g/l, while the concentrations in Bajpara and the nearby village Gobindapur are below 100.0 ? g/l. The magnitude is considered highest in six villages and the severity is in order of Belgaria > Ghatugachi > Digra > Nizra > Kashimpur > Muktipara. The results showed that the arsenic concentration in the groundwater in Belgaria was 231.0 ? g/l with mean and median value of 217.28 and 219.0 ? g/l respectively. Contamination of the groundwater has become a great challenge for providing safe drinking water to the majority of the population in this area. The people of this region are continuously being exposed to arsenic toxicity causing serious health hazards which is very alarming and requires proper management.

Abstract: Flood is often said to be a phenomenon that leaves harmful effects by submerging lands and coastal areas. Flood control is in fact said to all preparations and methods that lead to the reduction of the harmful effects of a flood. The point we want to reach in this paper, is to find out the rate of the submergence of the flood plains in the edges of the rivers with different return period discharges in Golestan province of Iran.
Since the data periods in stations are different and because of the fact that some stations wre established in the area from 1337 to the recent years, after surveying and doing the competence data test based on Matusen Fon relation, the data period was selected from 1350 up to now. Among the mentioned stations, some were newly-built and some had a lot of lost data, so, their data was not enough in the best fit test and therefore was removed.
After completing and prolonging this data by means of SMADA software, HEC-SSP software was used in order to estimate the maximum instantaneous discharge of these stations with different return periods. Then, the file of geometrical characteristics of the sections of the flood channels of the basin under study was provided in HEC-GeoRAS and then was exported from GIS to HEC-RAS. Then the flood Encroachment for the rivers of the area was done by the flood hydrographs with different return periods which was obtained by HEC-SSP software, and the area under threat was specified.

Abstract: Pinus wallichiana cones collected from two elevations viz., (1500-1700m) and (1700-1900m) and stored for two weeks produced seeds with maximum germinability. At 1500-1700m elevation the seeds showed maximum germination (79%) and germination value (9.97) in case of fresh seeds and 85% and 11.80 in case of stored seeds. However, at 1700-1900 m elevation maximum germination of 81% and germination value of 11.89 in fresh seeds and 85% and 11.62 in case of stored seeds was observed. Hence collection of Pinus wallichiana cones in western Himalayas can ben started during 1st week of October and cones can be stored at room temperature before their dehiscence and seed collection.
