Abstract: Earth observation satellites provide the vantage point and coverage necessary for studying our planet as an integrated physical and biological system. Land use planning involves the inventory of the land resources and taking stock of the present scenario. Land use planning does not only involve suggesting alternate land use but also should consider factors, which affect the other types of land use. The present study can help in the reconnaissance survey of the area as well as integrating the information to look at different scenarios in the landscape and plan for sustainable use of the land. The approach has given good insight into the areas potential for alternate land use. The action plan prepared using this approach shall help the adminstrators in taking decisions regarding resource use and mobilization of support for a change. The action plan not only serves as a guide but also as a blue print for natural resource management for sustainable development. Compilation and collation of information of the area under study is the preliminary task in planning. The availability of remotely sensed data at high spatial and temporal resolution has facilitated the planners to access natural resource information at a rate faster than never before. Land use map is the first map, which any planner would need to look at the extent of use to which the land is put. For purposes of planning at the district level the 1:50,000 maps generated using the IRS-P6 data were found to be suitable. Soil map and hydrogeomorphology map were the preliminary dataset generated from the satellite data. Information derived by integrating and analysing the above factors was produced as derivative maps which are the action plan maps.

Abstract: The present study is aimed at screening for the concentration of nutrients and chlorophyll - a in mangrove environment of Red Sea coast of Yemen. N-NO2 concentration ranged from 0.50?g/L at Kamaran Island to 2.20 ?g/L at Al-Zubayr with mean of 1.483 ?g/L. N-No3 concentration ranged from 0.70 ?g/L at Kamran Island to 3.10 ?g/L at Dhubab with of 1.917 ?g/L, N-NH4 concentration ranged from 0.30 ?g/L at Al - Zubayr to 1.00 ?g/L at Dhubab with mean of 0.608 ?g/L. P-PO4 concentration ranged from 2.50 ?g/L at Al - Zubayr to 6.10 ?g/L at Al - Hodiedah with mean of 4.333 ?g/L. Si-SiO2 concentration ranged from 15.30 ?g/L at Al-Zubayr to 23.40 ?g/L at Al - Hodiedah with mean of 18.833 ?g/L. Chlorophyll-a concentration ranged from 0.200 ?g/L at Al-Zubayr to 0.320 ?g/L at Al-Hodiedah with mean of 0.263 ?g/L. The maximum concentration of nutrients, found at the levels of minimum oxygen and relatively high ammonia concentration, is usually attributed to recycling of nutrients by phytoplanktonic and bacterial activities. The high concentration of phosphate may be attributed to the freshwater inflows as a result of heavy rains in the highlands. The high concentration of silicate may be attributed to severe sandstorms affecting the coastal areas. The concentration of chlorophyll-a may be attributed to the water mass that contains nutrients as well as phytoplankton.

Keywords: Phytoremediation, methyl parathion, p-nitrophenol, hydroquinone
Abstract: Phytoremediation is a green technology, where plants are used to remove contaminants (organic or inorganic) from soil. This is the first report of using an indigenous plant for the purpose of phytoremediation. Maize, a crop plant has been used for this purpose where uptake of methyl parathion by the plant has been shown to occur 80%. Average uptake of p-nitrophenol is 64%. Streptomycin behaves like organic matter and affects the enzyme p-nitrophenol 4-hydroxylase both in the root and shoot. The enzyme has been demonstrated to occur in a plant for the first time. Influence of soil organisms is both positive and negative in the uptake of organophosphate. The results obtained were confirmed by HPLC. Methyl parathion hydrolyses to p-nitrophenol, which is further metabolized to hydroquinone with nitrite release. Maize showed an uptake of 31.29% of methyl parathion in unsterilized soil. In the presence of streptomycin and in unsterilized soil uptake of hyroquinone is 99.78% and 98.36% respectively, while in sterilized soil there was no degradation.

Abstract: Noise as one of the important hazardous factors in workplace, which can lead to health injury, decrease in safety and efficiency and financial loss for companies and factories. To control noise in a specific industry, awareness of its sound characteristics such as enivonmental sound level, worker ' s exposures level and noise frequency distribution is substantial at different stations. The aim of this research is to describe the sound characteristics of equipments, and to investigate the sound exposure level of workers in Tobacco industry. Within this context, environmental noise and frequency analysis in five main parts of the plant were measured. Based on ISO: 9612 standards, the A-weighted sound pressure level was measured in 565stations using CEL-257 sound level meter. According to ACGIH guideline noise, areas were divided into three groups including safe area, caution area and danger area. Noise analysis in one octave band and computation of the workers ' exposure level of 8 hours were performed in 21 points of danger areas (> 85dBA). The maximum and minimum sound pressure levels were in cigarette workplace 2(b) with 95.5 dB(A) and in cigaretter workplace 4 with 68.2 dB(A) respectively. Correlation test between environmental souind levels and 8 hours noise exposure indicates their high relation (sign: 0.000. Pearson co:0.944). Frequently analysis results have shown that most sound levels were at frequency 500 to 2 KHz and in most measurement points, sound level was high at frequency 4 KHz in which makes the PTS risk subsequently.

Keywords: Planktonic foraminifera, shell weights, upwelling, Western Arabian sea
Abstract: Planktonic foraminifera shell weights have been recognized as possible proxy for surface water carbonate ion concentration [CO3-] and atmospheric CO2. However, to utilize this proxy, it is important to understand whether shell weights truly reflect surface water [CO3-]. We uitlize shell weights of Globigerina bulloides and Globigerinoides ruber in the size range of 300 to 355 ?m from a sediment core recovered from above the lysocline in the upwelling region of western Arabian Sea. Shell weights of G. ruber and G. bulloides show significant correlation with their shell size from recent to 16 kyr, which suggests that shell calcification was controlled by optimum growth conditions. On the other hand, during 16 to 22 kyr, there is no correlation between shell weights and shell size. However, shell weights of G. bulloides exhibit significant negative correlation with annual sea surface temperature which suggests that G. bulloides calcification might have been controlled by surface water [CO3-]. Therefore it is suggested here that shell weights of G. ruber and G. bulloides cannot be utilized to reconstruct surface water [CO3-] in this region.

Abstract: Greenhouse pot culture studies were conducted to evaluate the bioremediation potential of spinach for removal of cadmium. The results indicated that spinach was able to take up cadmium in substantial quantity in the shoot. There were no visual cadmium toxicity effects on spinach and no significant reduction in the dry matter yield up to 20 ?g g-1 cadmium. Signifiant growth retardation of fenugreek crop grown after spinach was observed at all the levels of cadmium, with no cadmium uptake in the shoot. This study revealed that spinach is a cadmium-tolerant crop and can be used for phytoremediation purpose.

Abstract: Conservation of biodiversity in managed landscapes is of critical importance due to the rapid degradation and loss of primary habitat in the tropics. Soppinabetta forests are farmer-managed, fragmented evergreen forests of the Western Ghats biodiversity hotspot in India. We hypothesized that these forests have immense importance in conservation of epiphytic orchid flora, although management intensity may differentially affect the diversity. Orchid diversity of the Soppinabetta forests of two degrees of management (sustained Soppinabetta, N = 11; degraded Soppinabetta, N = 4) has been compared with protected reserve forest fragments (N = 6). A total of 3537 orchid individuals of 41 species were recorded from 1.05 ha area; 39 species were found in the Soppinabetta forests. Orchid species richness was highest in sustained Soppinabetta forests (26.2) compared to degraded Soppinabetta (23) and reserve forest fragments (20.5). Non-metric multidimensional sealing ordination revealed that the orchid community of the degraded Soppinabetta was distinct. It was found that even when the total alpha diversity was preserved, a shift in the orchid species can take place with anthropogenic disturbance. About 21% of the overall surveyed trees were phorophytes. Mean phorophytes ranged between 15% and 46.5% among three forest types. Compositional variation of phorophyte trees had little effect on orchid diversity of the fragments. The present study shows that the deficiency of properly protected reserve forests can be compensated by the farmer-managed local Soppinabetta forests for epiphytic orchid conservation in the region. Comparison with other studies revealed that the Soppinabetta forests harbour high local orchid diversity in the entire Western Ghats.

Abstract: A pilot study was conducted to assess the economic impact of weather forecast-based advisories issued to 15 of the 127 Agrometerological Advisory Service (AAS) units of the Ministry of Earth Sciences, Government of India. Six seasons comprising three Kharif (summer) and three Rabi (winter) during 2003-2007 were chosen. The major crops chosen for the study included food grains, oilseeds, cash crops, fruit and vegetable crops. The sample set consisted of 80 farmers, comprising 40 responding and 40 non-responding farmers. The main aim was to study the percentage increase/decrease in the yeild and net return due to AAS. Results obtained suggests that the AAS farmers accrued a net benefit of 10-15% in the overall yield and a reduction by 2-5% in the cost of cultivation over the non-AAS farmers.
